Can Halogen Lights Be Replaced with LED?
1 Answers
Automotive halogen lights can be replaced with LED lights, but it should be noted that the focal points of the reflector bowl and lens in the original halogen bulb differ from those of LED lights. The light beam formed by LED lights may not be as uniform, and depending on the quality of the product, LED lights with poor heat dissipation and constant current effects may have relatively inferior illumination performance. Moreover, inadequate heat dissipation of the lights can significantly impact the vehicle itself. Here is some relevant information about halogen lights: 1. Principle: The main difference between halogen bulbs and other incandescent lamps lies in the fact that halogen bulbs are filled with halogen gases (usually iodine or bromine) inside their glass envelopes. The working principle is as follows: when the filament heats up, tungsten atoms evaporate and move toward the glass tube wall. As they approach the wall, the tungsten vapor cools to approximately 800°C and combines with halogen atoms to form tungsten halides (tungsten iodide or tungsten bromide). 2. Advantages and Disadvantages: Halogen lights are an improvement over incandescent lamps, retaining their advantages: simplicity, low cost, easy brightness adjustment and control, and excellent color rendering (Ra=100). At the same time, halogen lights overcome many shortcomings of incandescent lamps, such as short lifespan and low luminous efficiency.
