R&D TEAM: MORE CUTTING-EDGE BY THE DAY
INTELLIGENT PROTECTION SYSTEM
The IPS protects lighting fixtures from water infiltrations, which can occur if there
are faulty junctions between the cables in outdoor or underwater applications.
This innovation, patented by L&L, also guarantees electrical protection
against polarity reversal, hot plugging, ESD and power surges,
which can occur if there are faults in the electrical circuit.
PROTECTIVE IMPEDANCE DEVICE
The PID protects lighting fixtures from electrical phenomena
external to the system, such as static electricity accumulation
or electromagnetic interference coming from the mains power.
Generally, these are events with a low energy content.
ELECTRICAL PROTECTION SYSTEM
This symbol identifies a lighting fixture with EPS, which protects
fixtures for indoor applications against electrical problems.
This innovation, patented by L&L, guarantees electrical protection
against polarity reversal, hot plugging and voltage spikes of up
to 48Vdc, which can occur if there are faults in the electrical circuit.
SURGE PROTECTION DEVICE
The SPD protects lighting fixtures from electrical
phenomena external to the system, such as power surges.
In particular, this device is specifically for protection
against serious events with a high energy content.
TEMPERATURE CONTROL BUILT IN
This is an NTC thermistor mounted on the LED board to protect the lighting
fixture against overheating. Should the product function at an operating
temperature greater than the maximum temperature at which it can operate
correctly, the protection is activated and gradually reduces the power.
The protection rating IP69K indicates an electrical device’s resistance to cleaning
with high-pressure, high-temperature spray-downs. When the fixtures are installed
in urban or industrial applications where heavy cleaning is carried out using
high-pressure washers, functioning, resistance, service life and appearance
are guaranteed even under these conditions. (compliant with ISO 20653)
