What color is the car halogen lamp

The color of automobile halogen lamps is yellowish. The principle of the halogen lamp is to inject halogen gas such as iodine or bromine into the bulb. Under high temperature, the sublimated tungsten wire reacts chemically with the halogen to emit yellow light. The filament of the halogen lamp is a tungsten filament, and the cooled tungsten will re-solidify on the tungsten filament to form a balanced cycle to avoid premature breakage of the tungsten filament. Therefore, the life of halogen lamps is longer than that of ordinary incandescent lamps.

The color of car halogen lamps is related to color temperature. The color temperature of car lamps is the color of light emitted by the bulb. The lower the color temperature, the warmer the color tone. Red-turn yellow-whitish-bluish). Generally, the color temperature of automobile halogen lamps is between 2000K-40 00K (K stands for color temperature, which is a physical quantity of the color of the light source), and the color is yellowish. If the color temperature is too high (>5000K), it will show blue light, such as a xenon lamp, but the light of this color temperature has poor penetration in haze weather and is more dazzling.

Automotive halogen lamps are generally used in ordinary cars with low brightness, but they inherit the advantages of traditional incandescent lamps. They have low cost, easy control and adjustment of brightness, good color rendering, and milder light. Compared with LEDs and xenon lamps, they have penetrability. Stronger, this is because the penetration power is related to the color temperature (K value) of the light. Generally speaking, the lower the color temperature, the better the penetrating power, on the contrary, the higher the color temperature, the worse the penetrating power.
