SPT04-10-002 UHL3.1
FOR LIGHTING OF INTERIORS AND DRIVER'S CABS IN MOTOR AND ELECTRIC VEHICLES
Description
SPT04-10-002 UHL3.1 ceiling light fixture has been designed for lighting interiors and driver's cabs of vehicles (buses, trolleybuses, trams). It is designed to operate from a DC power network.
The light fixture consists of an aluminium base on which there are installed LED direct switch modules, a diffuser made of opaque extruded polycarbonate providing screw-free fastening on the base, plastic end plugs.
The lamp has two lighting modes: continuous lighting and standby (emergency) lighting.
- - The continuous lighting is provided by the white LED module. The illumination level meets the requirements of SMT ET007-04 Standard of the Ministry of Transport of the Russian Federation.
- - Standbt (emergency) lighting is provided by a separate LED module. Thus, the illumination of a passage and platforms is kept at the level of least 0.5 lux, which meets the requirements of the Standard of the Ministry of Transport.
The power supply circuits of the continuous and standby lighting are not electrically connected.
The use of LEDs provides for reduced electricity consumption and maintenance costs of the light fixture. The LED light fixture instantly enters the operating mode, its light characteristics almost do not depend on the ambient temperature.
