LED red - and white emission color buffer lamps are used to indicate railway equipment with caution lights.
The work-piece is used for ordinary electric bulb buffer lamps changing.
Buffer lamps are powered by the following types of direct-current power supply:
modification № 1 supply voltage - 50±5 V, ripple rate data- up to 100%.
modification № 2 supply voltage - 110±5 V, ripple rate data- up to 100%.
modification № 3 supply voltage - 24±2 V, ripple rate data- up to 100%.
modification № 4 supply voltage - 75±5 V, ripple rate data- up to 100%.
Axial lighting force by nominal supply voltage and temperatures from -60°C to +60°C:
red buffer lamp – min 160 cd
white buffer lamp – min 530 cd
Advantages of buffer lamps over electric bulb lamps:
2 times longer service life
25 times higher performance reliability
catastrophic failures are excluded; a few tens of self-supporting light-emitting-diode arrays are used in buffer lamps instead of one bulb
light lens high impact property
The device is meant to be used for operation under the conditions of temperate- and frigid climate (UHL) category 1 as per GOST Standard operating temperature from -60°C to +60°C, maximum air humidity by 25°C - 100%.
LED buffer lamps security level is IP54 as per GOST Standard.
