Komatsu's LED headlights provide rapid and strong lighting with low energy consumption.The colour temperature of the new lights is 5700 Kelvin, which is more powerful than xenon. And with an energy consumption of only 43 watts, they emit a flux of 3000 lumen. LED technology is considered very reliable, resulting in LED headlights having a long service life. LED lighting uses diodes that are tolerant of vibrations and are enclosed in a sturdy casing. The headlight glass is made from a polymer material with greater durability than standard glass while also exhibiting good heat dispersion properties.
The lights feature integrated thermal controls to protect against overheating, as well as voltage surge and reverse polarity protection. LED lighting contains no mercury, a substance found in xenon lighting technology. LED lighting is optional on all new Komatsu forwarders from March and on the 901TX.1, 911.5 and 931.1 harvesters from September.
