What are three-color temperature automotive LED headlights?
Three-color temperature car headlight bulb refers to an LED car headlight bulb that can emit three-color light, white light, yellow light, and yellow-white light by switching.
The causes of three-color temperature headlights
Why does a car light emit light with three color temperatures? What are the benefits of three-color temperature car headlights? Let’s start from the beginning:
Many years ago, cars were equipped with halogen lamps as standard, with a color temperature of about 2800K and yellow light. Later, Audi equipped LED headlights as standard, with a color temperature of 6000K and white light.
Most people still like the snow-white LED headlights very much. However, in rainy and foggy weather, the penetrability of white light is indeed poor. Under such circumstances, three-color temperature lights were born.
Characteristics of three-color temperature car lights
The above mentioned the most commonly used color temperatures of car lights: 2800K yellow light (2500K golden light), 4300K yellow-white light, and 6000K white light. Three-color temperature LED car lights integrate these three color temperatures into one light.
Why integrate three color temperatures into one lamp? Because white light and yellow-white light illuminate the road more clearly on a sunny night, yellow light is more practical in rainy and foggy days.
One light with three colors takes into account both sunny and rainy days, allowing riders to switch lights on various occasions. This is one of the reasons why three-color temperature LED headlight are so popular among riders.
Everyone should know that white light is seven-color light, such as sunlight at noon, which has the best color rendering and is less likely to cause visual fatigue.
The yellow light has better penetrating power and is more practical in rainy and foggy days. Especially in cities with frequent thunderstorms and fog.
Yellow-white light has the characteristics of the above two color temperature LED headlights.
Usage scenarios
Dual-color temperature LED headlights have two usage scenarios: one is used as a LED fog lights, and the other is used as a headlight.
1. The first type is used as a fog light:
There are several common types of three-color LED fog lights. This LED fog light usually turns on white light or yellow-white light and is used as an auxiliary light for low beam; in rainy and foggy days, it turns on yellow light and is used as a fog light. It can be realized by turning it on and off. Color temperature switching is very convenient.
2. The second type is used as headlight:
Three-color temperature LEDs are used as headlights, usually installed in low beam. They turn on white light on sunny nights to illuminate the road more clearly. They turn on yellow light on rainy and foggy days, which makes them more penetrating and more eye-catching.
In fact, it is good to use yellow light on a sunny night, especially golden light, which is very eye-catching. When driving on the road, others can notice you from a distance. Don’t forget, in addition to lighting, car lights also have a function – the “reminder” function.
3. Add a usage suggestion: switch the lights to relieve visual fatigue after driving for a long time.
No matter what color of light, looking at it for a long time will inevitably cause visual fatigue. For example, if you drive on the highway and turn on the white light for two hours, you can switch back to the yellow light to adjust your eyes and nervous system and relieve visual fatigue to the maximum extent.
Disadvantages of three-color temperature headlights
1. The cost of three-color temperature headlights is higher than that of ordinary color temperature headlights.
The cost of tree-color temperature lamp beads is high.Because three-color temperature headlights synthesize two or three color temperatures on one lamp bead, the production process is higher than that of single-color temperature lamp beads.
The circuit cost of dual-color temperature headlights is high.
The color temperature circuit is also more complex than the single color temperature circuit, which is one of the reasons for the high cost.
2. The lighting effect of three-color temperature headlights is not the best
The three-color temperature lamp bead divides the original single-color temperature lamp bead into two. One side is a 3000K color temperature lamp bead, and the other side is a 6000K color temperature lamp bead. Therefore, the lighting effect is definitely not as good as the light emitted by monochromatic temperature lamp beads.
Installation suggestions
1. If the original car has fog lights (the original car fog lights can only emit yellow light), it is recommended to replace the original car fog lights with three-color temperature LED fog lights. The three-color LED fog lamp usually turns on white light or yellow-white light, and is used as an auxiliary light for low beam, illuminating the road more clearly, without blind spots; in rainy and foggy days, it turns on yellow light, and is used as a fog light, killing two birds with one stone.
2. If the original car does not have fog lights, you can replace the low beam of the headlights with three-color temperature LED headlights, usually with white or yellow and white lights, and with yellow lights in rainy and foggy days. Of course, when using white light, you can also switch to yellow light to achieve the effect of reminding the vehicle in front.
How to switch multi-color headlight lighting
Switching multi-color headlight lighting is very simple, you just need to turn off the headlights, then turn them on immediately, and the color temperature is switched. Drivers must operate under the condition of ensuring safety.
Conclusion
The three-color temperature LED lights can be dimmed at any time, and the color temperature can be switched by turning on and off, which sounds very cool. But the real purpose of the three-color temperature LED is not for coolness, but for driving safety.
On a sunny night, when the low beam is turned on, the fog lights are added as auxiliary lighting, so that the road is clearer, the vision is wider, and driving safety is ensured.
At present, dual-color temperature led headlights, four-color temperature LED headlights, five-color temperature LED headlights and colored light LED headlights have appeared on the market. Everyone can choose according to their free needs.
Therefore, it is a very humanized, practical, and very important design to design the car lights with two color temperatures for the car owner to switch freely.
