What is the function of halogen lamps?

[GiannaAnn]

Halogen lamps can replace the function of incandescent lamps, and they have a longer service life, easier brightness adjustment and control, and better color rendering of light. Because halogen bulbs have high luminous efficacy and great illumination brightness, they are suitable for occasions that require concentrated lighting. Working principle: The principle is to inject halogen gases such as iodine or bromine into the bulb. At high temperatures, the sublimated tungsten filament chemically reacts with the halogen, and the cooled tungsten will re-solidify on the tungsten filament, forming a balanced cycle and avoiding premature breakage of the tungsten filament. Therefore, halogen bulbs last longer than incandescent lamps. Impact: Many cars use traditional halogen bulbs, and more than 60% of traffic accidents occur at night or in poor weather conditions. The lighting effect of halogen bulbs is greatly reduced at night or in poor weather conditions. At this time, the driver's vision is severely affected, making them prone to fatigue, distraction, etc., and the probability of traffic accidents increases significantly.
