Abstract: This article briefly describes the reasons for the glare of led explosion-proof lamps. By changing the color temperature, it adjusts people's feelings about lighting and rationally selects lamps.
Keywords: led explosion-proof lamp; color temperature
1 Overview
The LED explosion-proof lamp gives everyone the impression that it is bright, bright, and even dazzling. What is the reason for this? How to improve it? The traditional method is to eliminate the occurrence of glare through different light distribution, and there are also ways for manufacturers to reduce the luminous flux. In fact, there is a very important factor here, that is, the choice of color temperature.
2 Technical indicators
Color temperature is an important parameter in the optical aspect of lamps. The more blue the light color, the higher the color temperature; the lower the color temperature, the lower the color temperature. The color temperature of the lamps is different, the light color is also different; the color temperature is stable below 3300K, the warm feeling; the color temperature is 3000--5000K for the intermediate color temperature, and there is a refreshing feeling; the color temperature is colder than 5000K. The higher the color temperature, the brighter, more glaring, and colder the feeling.
LED explosion-proof lamps generally used in workplaces should not use lamps with too high color temperature. The color temperature should be selected at an intermediate color temperature of 4000--5000K. This color temperature is close to the afternoon sunlight, which will not cause discomfort to the on-site personnel and can adjust the field work. The emotions of the staff are more conducive to the work on the spot.
