PICTOGRAPHY
Class II luminaire: luminaire whose protection against electric shock
is not only relevant to the main insulation, but also includes additional
safety measures, such as dual insulation or reinforced insulation.
These measures do not include ground devices as protection and do
not depend on the installation conditions.
Class III luminaire: luminaire whose safety against electric
shock is based on safe extra low voltage power supply.
Compliance with legislation is guaranteed only if the luminaire is
powered by a SELV safety transformer/driver in compliance with
legislation in force. The luminaire must not be connected to ground
conductors.
XX
Degree of protection against access of foreign bodies, dust and water.
To prevent the risk of fire, maintain the minimum distance indicated
from the bulb with lighting objects. This distance should be measured
along the optical axis of the luminaire to the closest lighting object.
CRI
Color Rendering Index: the degree of colour distortion under a
given light source in comparison with a reference light source.
The optimum colour rendition index is Ra=100.
lm
The luminous flux, measured in lumen, indicates the quantity
of light perceived by the human eye emitted by a light source.
In Davide Groppi lights with an integrated module, the deliverd
lumen flux is obtained from the photometric measurement.
In lights with a lightbulb included, the luminous flux is indicated
provided by the manufacturer of the lightbulb.
Luminaire designed to be powered by ENDLESS conductive tape.
Luminaire integrated with Casambi, the Bluetooth Low Energy (BLE)
technology for lighting control.
Luminaire with Extradark comfort system. The Extradark system
associates an optical TIR PMMA lens to an element that geometrically
shields the light beam viewing angle to obtain highly uniform lighting
and full beam control. The polished black light shield is used to control
the mirror reflection of the light, perfectly controlling the unified glare
rating (UGR* <19).
*Unified Glare Rating.
All Davide Groppi products are equipped with electronic light sources (LED).
The selection of diodes is carried out with the utmost care to guarantee
the highest levels of performance and luminous uniformity.
