R&D TEAM: MORE CUTTING-EDGE BY THE DAY
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.
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.
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)
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.
