Cool morning light promotes cortisol, the activating hor-\nmone. In the evening, when the blue component is missing, the sleep hormone melatonin is \nformed. High melatonin levels at night lead to more restful sleep, and we enjoy a positive start \nto the day through an increased release of the happiness hormone serotonin. The RECOVER \nluminaire taps this knowledge and supports the natural regeneration of patients, as the high \nindirect illuminance provides clear impulses to the inner clock..\nFour lights in one\nRECOVER combines four luminaires. Indirect, homogeneous ceiling lighting provides daytime \nbrightness for the patient, while the examination light is used for doctor’s visits. \nA reading light ensures refl ection-free illumination of the reading area. The nurse night light \nmounted on the side of the luminaire was integrated to avoid dazzling the patient at night.\nSchedule light moods\nThe aim was to make RECOVER particularly user-friendly. Lighting moods and intensity levels \ncan be programmed with simple software. You can even string together several diff erent pro-\ngrammes to form an annual schedule. The intensity and colour temperature changes automat-\nically with the season. The factory settings already store diff erent daily sequences, which you \ncan quickly adapt to your time requirements.\nThe next generation of contemporary healthcare lighting, RECOVER has been developed to \nsimulate a natural light pattern. This is achieved by the dynamically changing colour tempera-\nture. It varies from activating morning light to a sleep-promoting evening glow. The luminaire \nsupports the natural regeneration of the patient by supporting the human biorhythm. The 4-in-1 \nsystem includes ambient light, a reading light, a nurse’s night light, and an examination light \nwith a high CRI value which displays amorphous three-dimensional surfaces such as the skin \ncorrectly. RECOVER is designed to be particularly user-friendly. Lighting programmes can be \nquickly and fl exibly adapted.\n10\nxal.com\u002Frecover\n",9,{"image":50,"text":51,"number":52},"\u002Fmedia\u002Fimages\u002Faf\u002Ff73dffac5e85841f3d9e1879a1f521-285e0c8355.10.png"," Everything\non track\nMOVE IT 25\nrecessed \u002F surface \u002F suspended\nPlasterboard ceiling \u002F concrete ceiling\n3000 K, 4000 K\nIdeal application\nCommon rooms\nColours\nblack, white\u002Fblack, gold\u002Fblack,\nand special colours\n Always and \nanywhere\nSPADO square \u002F round\nrecessed\nPlasterboard ceiling \u002F grid ceiling\n3000 K, 4000 K,\nUGR ≤ 19, IP 44\nIdeal application\nCorridors & staircases\nColours\nwhite, black\nFRAME 40 \u002F 60 system\nrecessed\nPlasterboard ceiling \u002F concrete ceiling\n3000 K, 4000 K, TW (Tunable White)\nUGR ≤ 19, CRI 98\nIdeal application\nPatient room, examination room, \n24-hour nurses’ station, corridor\nColours\nwhite, grey\n Be free \nto sharpen \nyour profi le\nCombine with \nyour design\nSASSO 40 \u002F 60 \u002F 100\nrecessed \u002F semi-recessed \u002F surface\nPlasterboard ceiling \u002F grid ceiling \u002F \nconcrete ceiling\n2700 K, 3000 K, 4000 K, CWD (Col-\nour Warm Dimming), UGR ≤ 16, IP 44\nIdeal application\nPatient room, examination room, com-\nmon rooms, 24-hour nurses’ station\nColours\nMounting frame: white, silver, black\nHousing: white, black, and gold\nRefl ector: white, silver, black, gold, \nand chrome\nxal.com\u002Fproducts\n11\n",10,{"image":54,"text":55,"number":56},"\u002Fmedia\u002Fimages\u002Faf\u002Ff73dffac5e85841f3d9e1879a1f521-285e0c8355.11.png","Advanced sensor \ntechnology \nModern lighting management systems \nharness energy-effi  cient use of daylight. \nSensors on the ceiling determine where and \nhow much light is needed and control indivi-\ndual luminaires according to current lighting \nrequirements.

Radiating from the bed, the combined indirect\u002Fdirect modules enable a pleasant spatial \neff ect as well as targeted use as a reading and examination light. The indirect light component \nprovides a pleasant illumination of the ceiling. The light insets can be controlled separately, so that \nthe room light as well as the reading and examination light can be combined individually. The \nluminaire can also be used as a night light using the dimming function. This range of functions \ncomplies with medical specifi cations so that the lighting from VITA MED also meets the \nrequirements of a treatment room. The cylindrical illuminance of 450 lx, required to match the \ncircadian clock, is exceeded for both 50-year-old patients and nursing staff  alike. The working \nenvironment for doctors and nurses is improved, while patients receive an optimum light intensity \nfor healthy vital functions and a positive melanopic response. The individual light functions can be \noperated via conventional light switches and the patient's control device. DALI control is also \navailable as an option, allowing predefi ned lighting programs to be called up. The discreet supply \nduct of the lighting system integrates both single or three phase power as well as medical gas \nfi ttings and can be tastefully adapted to the desired design concept with a fascia panel.

This clearly shifts the focus to design \nmeasures that support patient recovery. Colour-changing \nlight's use is undisputed from a medical perspective. In \naddition to health-promoting aspects in intensive care, \nlighting enables the creation of an atmosphere that helps \npatients recover and provides staff with an activating \nworking environment. The combination of natural and arti-\nficial lighting plays a central role here because light is the \nstrongest pacesetter for the inner clock. No medication \nhas a comparably powerful effect. For patients waking up \nfrom a deep sleep, high illuminance significantly supports \nrecovery. According to the hospital supplier HT Health Tec \nGmbH from Heideck in Germany, over 2000 lux should \nhorizontally illuminate the bed's surface for several hours. \nA dynamic light curve is ideal for this.\nThanks to increasing digitalisation and lower costs, a large \nrange of intelligent lighting systems with dynamic light \nsequences are already available. However, the acceptance \nof such complex lighting systems stands and falls with its \noperation. Appropriate, user-friendly solutions are there-\nfore needed. How are multi-dimensional lighting systems \nunderstood, and – without training – operated? It has \nbeen shown that care staff often reject complex control \nsystems because nothing is as intuitive and fail-safe as an \nanalogue light switch.\nRegarding epidemics and pandemics, changes are already \nemerging in floor plan configurations of access areas to \ntake account of epidemiological requirements. Sustaina-\nbility, the ecological, and economic framework conditions \nare core concerns. Energy and resource-saving products \ncontinue to pose an acute challenge. This also applies to \nlighting.

In bright, open rooms with natural light \ncolours, the body can recover and regenerate better. Indirect light is particularly pleasant, as \nit makes the room appear larger. Since people in patient rooms spend a lot of time in bed, the \nlighting needs to be adapted to this position. The positioning and optical coverage of luminaires \nprevents bedridden patients being dazzled by room light. \nSmall reading lights are mandatory for each hospital bed, which must reach at least 300 lux at \nthe reading position. The light emission direction prevents patients in neighbouring beds from \nbeing disturbed. Orientation light and night lighting are particularly important since patients are \nin an unfamiliar environment. They help patients navigate while also providing caregivers with \nsufficient light for routine checks. For nursing procedures, illuminance should be at least 300 \nlux at the examination level.\nTo best support recovery, lighting should be synchronised with the patient's internal clock. This \nrequires sufficient illuminance to reach the patient's eye. Different light colours and illuminance \nlevels create a special, biologically effective light pattern, based on the dynamics of daylight \noutdoors. As a result, the patients’ physiological performance curve follows its natural rhythm, \ndespite staying in the room all day. This improves awareness activity, enhances memory, and \nstabilises the day\u002Fnight rhythm.

It is a place of encounter and \nexchange. Residents use this space to socialise, play card or board games, or watch movies \ntogether. Various factors need to be considered to ensure that lighting meets all these requi-\nrements and maintains a pleasant lighting atmosphere. The EN 12464-1 standard specifi es 300 \nlux for lighting in recreation rooms during the day. However, this is not suffi  cient, especially \nfor older people and more demanding visual tasks. At least 1000 lux illuminance should be \nprovided by additional luminaires. This can be achieved, for example, with separately switchable \nfl oor luminaires or reading luminaires. An important point in lighting design are the age-specifi c \ncorrection factors according to DIN\u002FTS 5031-100. Because vision deteriorates with age and the \neye's ability to adapt declines, the elderly need signifi cantly higher illuminance.\nIn addition, there is the infl uence of light on our circadian rhythm. The light colours in the inter-\nior are in direct contact with our hormonal system and control the day\u002Fnight rhythm. Elderly, \nless mobile care home residents often spend all day indoors. The biological standard specifi ca-\ntions for lighting are set out in DIN\u002FTS 67600. During the day, a melanopic and day-equivalent \nilluminance of ≥ 250 MEDI lux is recommended. This corresponds to about 370 lux at head \nlevel for a 32-year-old. As there is no synchronisation of the inner clock with standard lighting, \nthe consequences can be listlessness, poor sleep, or depressive moods. To counteract this, \nbiologically eff ective luminaires are used whose light colour changes dynamically with the time \nof day and reproduces the natural changes in daylight inside the room. XAL's full-spectrum \nLEDs enable these dynamics with an increased light-blue light component. In addition to excel-\nlent colour rendering, this also ensures high visual comfort and reduces eye fatigue. To create a \npleasant sense of space, high illuminance should be provided by large ceiling and wall surfaces \nwith indirect lighting.

An eye-friendly UGR value of ≤ 16 or ≤ 13 can be achieved with a high indi-\nrect light component. Higher illuminance is generally recommended above the desk.

Cylindrical illuminance should be at least 150 lux at eye level. \nThe modifi ed value of 300 lux is better suited. This can be achieved with suspended luminaires \nabove the counter or indirect light from the wall or ceiling.

This so-called inner clock is largely set by the two \nhormones melatonin and cortisol. Cortisol, also called the \nstress hormone, is released in high concentrations in the \nmorning and is the basis for alertness, focus, and physical \nand mental performance. In contrast, the sleep hormone \nmelatonin is responsible for regeneration by supporting \ndeep and relaxing sleep. \nBoth hormones are produced in the central brain and their \nrelease is directly regulated by the blue light components \nthat strike the retina. This means the amount of light blue \nlight we are exposed to has a direct infl uence on our \nhormonal system. The blue light components hitting the \neye's retina suppress the production of the sleep hormone \nmelatonin. As a direct result, melatonin levels increases \nsignifi cantly at night. If the melatonin increase is strong in \nthe evening, this results in signifi cantly raised cortisol in \nthe morning. We are effi  cient during the day and at night \nwe sleep soundly.\nIf artifi cial lighting is geared to these processes, it is \nperceived as more pleasant and also promotes physical \nhealth. Long-term studies in care homes, for example, \nshow that residents behave much more actively, openly, \nand independently when they are in rooms with a circadi-\nan-controlled lighting system. High illuminance levels with \nincreased blue wavelengths during the day and warm, \nlong-wave light colours in the evening hours reproduce the \nnatural daylight curve inside the room.\nHuman Centric Lighting (HCL)\nAn HCL concept puts the focus on people. Research has \nshown us for many decades what our needs are regarding \nlight. Yet in many places lighting is still seen as an expe-\ndient rather than a factor in our cognitive and physical \nhealth.\nHuman Centric Lighting is a lighting concept that off ers \nthe variability that the human organism demands. The \namount of light provided varies according to the time of \nday and season – it adapts to the natural daylight curve in \nthe respective area. Both the amount of light and the light \ncolour play a role.\nArtifi cial light in coordination with daylight\nThe best light source is always natural light. Therefore, \nthis should be used as far as possible and integrated into \nthe lighting concept, especially for buildings in the health \nsector. Large window areas and atriums allow natural day-\nlight to enter the building. Using smart sensor technology, \nmodern lighting control systems can already measure how \nmuch light is entering the room and adjust the supple-\nmentary lighting accordingly. This dynamic regulation \nmaximises natural brightness, paired with cleverly desig-\nned artifi cial light scenes.

This is achieved via \nboth the luminous intensity and the light colours. Out-\ndoors, the light intensity is several thousand lux – indoors, \n1000 – 2000 lux already affects our hormone system. \nLarge areas with high luminance are important here, so \nthat the sensitive receptors are reached over a large area \nof the retina.\nTo imitate daylight in terms of colour, the entire light spec-\ntrum must be covered, and the dynamics and variability of \nnatural light must be reproduced. The light colour is spe-\ncified as colour temperature in Kelvin (K). Ranges below \n3300 K are considered warm white, whereas light colours \nabove 5300 K are called cool white or daylight white. The \ncooler the shade of white, the higher the proportion of \nblue, short-wave components which have an activating ef-\nfect on the organism. In modern luminaires with full-spec-\ntrum LEDs, specific attention has been paid to achieving \na frequency content of the wavelengths that is close to \nnatural. Thus, artificial light achieves a biological effect \nsimilar to daylight.\nIncreased need for light in old age\nWith increasing age, fewer and fewer light stimuli reach \nthe retina. From birth, lens opacity and pupil constriction \nincrease, specifically allowing fewer blue wavelengths \nto reach the retina. However, this blue light is needed to \nregulate the day-night rhythm of the body and to trigger \nthe evening release of melatonin. \nIn nursing homes and care centres a decrease in activity \ndue to lack of light can be observed. If the body is not \nsufficiently activated during the day, sleep deteriorates – \nlistlessness and even depressive moods are the result. A \nresearch project at the Albert Schweitzer Clinic in Graz \nhas demonstrated a biological effect. The combined \namount of artificial and daylight was measured over 12 \nhours. On average ~ 530 lx \u002F h was measured. This provides \na daily dose of 6360 lx \u002F h. Depending on the location with \nrespect to the window and the patient's age, a daily dose \nof 5000  – 10000 lx \u002F h will achieve a biological effect. A \ndaily synchronisation of the inner clock is essential for an \nactive life in old age.\nFactors for near-natural lighting design\nLighting design oriented towards people is inspired by \nlighting conditions in the open air and their positive effects \non health – it is modelled on nature.

This \nis due both to the buildings' technical equipment and to \nincreasingly complex medical devices. Treatment and \nmonitoring equipment generate a constant background \nnoise level with a sound pressure level of around 70 dB – \nroughly the background noise of a canteen with 50 people. \nStudies have shown that the average noise exposure in \nlarge hospitals is equivalent to that on a major road.\nBetter sleep and quicker recovery time\nWe have known for a long time that noise is partly respon-\nsible for mental and physical stress. Environmental noise \nlevels have a demonstrable eff ect on our nervous system, \nour concentration, and our well-being. From 58 dB already \nthe heart rate increases, and it can lead to disturbed \nsleep. However, rest and sleep are the most important \nfactors in recovery and rehabilitation. Just as a long-term \nincrease in noise levels makes us tense, silence has a \nrelaxing and health-promoting eff ect. \nBalanced room acoustics are just as benefi cial to recovery \nas stabilising the patients' circadian rhythm. Biodynamic \nlighting concepts support natural hormone levels during \nthe course of the day and thus regulate the alertness and \ntiredness curves. The higher the activation during the day, \nthe more relaxed and regenerative the sleep. In addition, \nreduced noise levels in the hospital are benefi cial for the \nregeneration of patients and reduces their length of stay \nin hospital.\nModern acoustic products\nDesigning rooms such that people feel comfortable in \nthem is a central requirement of modern architecture, \nlighting, and acoustic planning. This is particularly true in \nthe health sector. For many people, visits to the doc-\ntor and hospital stays are associated with anxiety and \nnervousness. Here, anticipatory spatial planning can help \nlower stress levels, reduce tension, and allow people to \nfeel safe in the treatment environment. This begins at \nthe reception or in the waiting area and continues in the \nexamination room as well as at the 24-hour nurses’ station \nor in the patient's room. \nBright, calm, and friendly rooms counteract the clinical \nsterility of a hospital environment. In addition to pleasant, \nhomogeneous lighting, the room’s acoustics also play their \npart. The more balanced the background noise, the better \nthe organism can rest. Modern, design-oriented acoustic \nelements optimise the acoustic conditions in the room and \nact as decorative design elements that guide the patient's \ngaze.\nOptimised communication in the hospital\nIn addition, balanced acoustic planning improves the qua-\nlity of communication. In a medical environment, it is es-\nsential that the doctor, carer, and receptionist are clearly \nmutually intelligible and that the fl ow of information is not \nimpaired by reverberation, disturbing sound propagation, \nor background noise. Speech intelligibility in particular \nplays a major role. It must be suffi  cient to enable informa-\ntion to be passed on clearly and quickly. However, privacy \nmust be maintained during confi dential medical consul-\ntations. For example, at the 24-hour nurses’ station it is \nimportant to be able to communicate the most important \nthings quickly while exchanging sensitive data without this \nbeing overheard by other patients. Good room acoustics \ntherefore have a positive eff ect on the well-being and \nrecovery of patients and also optimise the processes in \nhealthcare facilities themselves.\n64\nHealthcare facilities\n",64,{"image":270,"text":271,"number":272},"\u002Fmedia\u002Fimages\u002Faf\u002Ff73dffac5e85841f3d9e1879a1f521-285e0c8355.65.png","Stress reduction for staff\nHealthcare workers operate under stressful conditions. \nThey carry out critical activities and must make serious \ndecisions – often under high pressure. Precision in every \naction is a prerequisite, as is efficiency in treatment, to pro-\nvide adequate care to all patients as quickly as possible.\nHigh noise levels act as an additional stress factor. It \naffects both the well-being of the staff and the quality of \ntheir work. Studies have shown that the psychological \neffects of noise in clinical settings have a negative impact \non concentration and performance, as well as accelerating \nfatigue. Poor comprehension, irritability, and a feeling of \nbeing overwhelmed thus put a strain on medical support \nas well as on the relationship with the patient. Room \nacoustics tailored to requirements counteract this by crea-\nting a harmonious working environment even where high \nnoise levels are unavoidable. This increases the quality of \nwork and the satisfaction of the staff.\n \nAge-appropriate acoustic conditions\nElderly people are overrepresented in hospitals and care \nhomes due to their physical constitution. Since visual and \nauditory performance declines with age, lighting and room \nacoustics need to be adapted accordingly. Appropriate \nacoustic measures enable elderly patients to perceive \ntheir surroundings better and to organise their day more \nactively. Improved acoustics also promote communication \nand participation in social life in the care home.\nSound-absorbing surfaces are ideal because they reduce \nthe reverberation time and thus optimise speech intelligi-\nbility. This has a considerable influence on the relationship \nbetween doctor and patient, for which mutual intelligibility \nis critical.\nBespoke acoustic planning for healthcare facilities\nIn the health sector, acoustic planning is indispensable. In \nplaces where people get back on their feet after illness \nor accidents or reorient themselves, environments are \nneeded that facilitate this.\nThe requirements for comprehensive room-acoustic plan-\nning in the healthcare sector are many and varied. Nume-\nrous standards must be considered, as well as the individual \nneeds of patients. To meet this complexity, we work with a \nnetwork of different partners. This allows us to perfectly co-\nordinate lighting and acoustics.

For employees in healthcare facilities, \nlighting must meet the requirements of the visual task \n– from examinations to care and service to laboratory \nactivities. To ensure that patients feel comfortable in their \nrooms, the lighting should both comply with standards and \nalso be individually adaptable. The lighting should also be \neasy and intuitive to control. \nThis is where simple, self-explanatory operating devices \nhelp. Special functions may not be immediately apparent \nto the user, but they are all the more helpful for building \nservices. These include integrated power measurement, \nsystem diagnostics, operating hours counters, and status \nreports.\nLight output as required\nLarge hospitals and care homes are busy around the \nclock. In addition to medical equipment, lighting is a major \ncost factor. Sensor-controlled luminaires increase comfort \nand safety, and also reduce energy costs in the long term \nby regulating light output as required.\nSensors measure movement and ambient brightness \nand switch on the lighting only where needed. Modern \nlighting management can control each individual luminaire \nseparately and thus dim or switch off  the light in unused \nrooms or in areas illuminated by daylight. In the case of \nluminaires close to windows, this saves up to 50% energy. \nOrientation lighting in corridors or staircases can also be \nplanned according to time of day and dimmed during quiet \nperiods. \nSmart sensors contribute signifi cantly to patient recovery \nby measuring important indoor climate values. Air humidity, \nair quality, sound levels, and room temperature are all fac-\ntors that infl uence the well-being of the people in the room \n– which is particularly crucial when patients are in their \nrooms for days or weeks at a time. If the room climate is \noptimised based on these parameters, this can noticeably \nshorten the recovery time and the stay in hospital.\nIndoor climate analysis with IoT sensors\nIf the values are to be more than just a snapshot, an \nextension with the DALI-controlled XAL's sensors is \nrecommended. These off er a comprehensive indoor \nclimate analysis. In this process, the measured values are \nrecorded and evaluated over a certain period, whereby \ntrends emerge. Analyses of the presence sensors record, \nfor example, the bed occupancy rate or the activity of pa-\ntients, which in turn can be considered in cleaning or room \nallocation. Based on indoor climate assessments, sensible, \ncost- and time-saving plans can be drawn up for ventila-\ntion or the operation of air-conditioning systems.\nHCL: Faster recovery through \ncircadian daylight patterns\nPatients recover more quickly the more comfortable they \nfeel in a healthcare facility. Suitable lighting systems \ncreate a feeling of calm and security and support the \nregeneration of body and mind by adjusting the lighting \nto the needs of the human organism. Since patients and \nresidents often spend long periods in closed rooms, it is \nessential to create lighting conditions that are as close as \npossible to natural daylight. \nHuman Centric Lighting (HCL) is used for this purpose. \nDynamic colour gradients imitate the natural daylight \ncurve from cold white, activating light in the morning to \nrelaxing, warm white light colours in the afternoon and \nevening hours. Slow dimming and gentle changes between \nlight scenes make the lighting pleasant and lively. Bright-\nness and lighting mood vary both from morning to night \nand with the seasons. A modern lighting system's pre-pro-\ngrammed or manually controllable algorithms can equip \nthe lighting with diff erent curves and thus optimally adjust \nthe light to its natural equivalent at any given moment.\n66\nHealthcare facilities\n",66,{"image":278,"text":279,"number":280},"\u002Fmedia\u002Fimages\u002Faf\u002Ff73dffac5e85841f3d9e1879a1f521-285e0c8355.67.png","Area-adapted, fl exible lighting control\nEach area in a hospital has diff erent lighting require-\nments. Multiple lighting standards apply, each of whose \nlimit values must be met. For example, diff erent lighting \nconditions are required at a 24-hour nurses’ station, where \nstaff  carry out computer work, than in a waiting room or \nin a dental treatment chair. The lighting system must be \nfl exible across administrative desk activities to diagnostic \ndiscussions to lighting in a care centre's common room. \nTo ensure that this complexity is straightforward for the \nbuilding services, the control systems can be maintained \ncentrally. Wireless solutions enable remote control and \nthus rapid response to changes in demand in individual \nwings of the healthcare facility.\nStraightforward operation and central management\nEven though light plays an important role in the health and \ncare sector, it should not cost employees more attention \nthan necessary. It is therefore necessary to implement \ncomplex technology in simple systems. The lighting con-\ntrol system must be easy to operate. The more intuitive \na system, the shorter the required training time and the \nfaster it can be commissioned. If support is needed, re-\nmote maintenance and confi guration save time-consuming \ntravel. Cloud support provides a quick overview of multiple \nsystems. In large hospitals, a doctor's offi  ce, or a care \ncentre, lighting is best combined in a system that can be \neasily and centrally managed.\nData mining in the health sector\nParticularly revealing data is used in the health care sec-\ntor. This is precisely where lighting systems equipped with \nsmart sensor technology can provide valuable insights. \nFor example, movement or air conditions in patient rooms, \nwhich in turn can be used to derive cleaning schedules or \nclimate control. The lighting system provides more than \n\"just\" the right lighting here. Collected values and data \nanalyses contribute to smart, energy-effi  cient building \nuse and provide insights into the patients’ regeneration \nprocess.\nRequirements\n• Energy Monitoring Converter\n• Current transformers on measuring circuits\n•  Calculating the current consumption from the dimming \nlevel\nMeasured  \n• Power consumption\n• Network quality\n• Patient attendance history \n•  Patient activity (for patients who must be deliberately \nactivated or who must remain still)\nxal.com\u002Fsensor-health\n67\n",67,{"image":282,"text":283,"number":284},"\u002Fmedia\u002Fimages\u002Faf\u002Ff73dffac5e85841f3d9e1879a1f521-285e0c8355.68.png","    2\n   1\n   5\n   6\n   1\n    3\n  4\n   6\n   5\nPatient room \nplanning example\nThe lighting in a patient's room must meet many require-\nments.
