Matsushita Electric Works successfully develops LED headlamps and compartment LED lighting for fireproof railway vehicles

Matsushita Electric Works announced that it has developed a "car LED lighting" that meets the fire protection requirements of subway vehicles. With a power consumption of 26W per unit, the power consumption is expected to be reduced by about 40% or more compared to the conventional 40W fluorescent lamp appliance (about 47W).

The life of the LED lighting in the compartment is about 40,000 hours, which is about 3 times that of the above-mentioned conventional fluorescent lamp. Using a non-flammable glass cover, the LED with a color temperature of 5000K improves the brightness in the cabin. The luminous flux is about 2000lm and the energy consumption efficiency is 77lm/W. The size is 1280mm x 80mm x 82mm and weighs 4.5kg.

In addition, Matsushita Electric also announced that the company has developed "LED headlamps for railway vehicles" trial products using its own developed optical design technology, thermal design technology, and quality evaluation technology. Headlights for vehicles currently use halogen-enclosed luminaires (a kind of incandescent lamp), and the newly-developed LED headlamps have a lifetime of 20 times that of 40,000 hours (light flux maintenance rate drops to 70%. Time). In addition, the power consumption is about 1/5 of the halogen-enclosed lamp (32W for the main lamp and 16W for the auxiliary lamp). The use of LEDs in the headlamps is expected to reduce the power consumption by about 80%.
