Traffic lights P1.1-AT and P1.2-AT are intended for regulation of the pedestrian traffic at pedestrian crossings. The LED modules (MS) of red and green colors are used in traffic lights P1.2-AT as a light source.
Symbol images of pedestrian traffic lights correspond to the Appendix B of DSTU 4092-2002. MS are built in the traffic light housing. The housing is made of black or gray impact-protected polycarbonate (the type of the housing is defined at the order).
The nomenclature of MS includes modules for the main pedestrian traffic lights of standard sizes 200 and 300 mm. MS favorably differ from modules with incandescent electric lamps in basic impossibility of a false color illumination of the disconnected sections at their lighting from the outside, in bigger brightness, by 10 times lower power consumption and essential higher reliability.
Light-emitting diodes in the LED module are included in such a way that breakdown to 20% of light-emitting diodes doesn't cause the decrease in light intensity of the module, due to compensation of a light flux by other light-emitting diodes.
MAIN TECHNICAL CHARACTERISTICS:
- Diameter of a lens working face, mm 200/300
- Nominal power supply voltage, V 220 +/-40
- Power consumption of one section of the traffic light, W, no more than 10
- Axial luminous intensity of signals, Cd, not less than 200
- Range of ambient temperatures, °С from - 40 to +60
