Car headlights from the original halogen lamp, to the later xenon lamp, and now many vehicles equipped with LED lights, so which of these three lights is good, what are the advantages and disadvantages? Today, I will discuss with you!

Let’s take a look at the summary version, let’s compare it from the color temperature, manufacturing cost, brightness, and service life. (Color temperature refers to the cost of color contained in the light, simply understood that the higher the color temperature, the whiter the light color, and vice versa, the lower the light color, the more yellow the color.) )

From the difference in color temperature, it can be seen that xenon lamps and LED headlights are more suitable as primary lighting, while halogen lamps are more suitable as fog lamp auxiliary lighting.

The color temperature of the halogen lamp is about 3500K, the light is warm yellow light, and the old light bulbs at home, filled with iodine or bromine and other halogen elements of the gas, after the electricity is turned on, the tungsten filament inside glows, its principle is that electricity is converted into heat energy for luminescence, but the conversion process will waste 90%, only 10% into light energy. And it is easy to high temperature and short life. The advantage is that the price is cheap and easy to maintain, and it is basically used in steering brakes.

Xenon lamp is filled with inert gas with xenon gas, the color temperature is cold white light between 5500~6000K, the color is similar to daylight under strong sunlight, the brightness is almost 3 times that of halogen lamp, the lighting effect is stronger, strong penetration, suitable for rainy days, foggy days. However, the light dissipates heat, and it is necessary to cooperate with the lens to concentrate the light, otherwise it is very dazzling when the high beam is illuminated. Working principle, high-voltage xenon generates an arc and then emits light, but because of the need to convert the low-voltage of the vehicle into high voltage, the brightness of the xenon lamp will be relatively slow, and it will take a while to become fully bright.

The color temperature of LED lights is also between 5500-6000K, which is cool white light. It is a power generation diode to generate a light source, which can directly convert electrical energy into light energy, without waste, the same electric energy is more than 3 times that of halogen lamps, and will not overheat, it can be said that it is bright and power saving. Secondly, the manufacturing process is high enough LED headlamps do not need lenses to do similar point light sources, without lenses, you can reduce the attenuation of brightness, and the brightness can be higher than that of xenon lamps. LEDs and the like are also common in the home, and more and more luxury cars are beginning to use LED lights as headlights.

In general, halogen, xenon, LED three PK, LED is better, if economic conditions permit, and vehicle configuration is also allowed, you may wish to configure a pair of LED headlights for your car to feel it!
