Comprehensive analysis of LED lights and xenon lights to see the future development of lights
LED lights are no stranger to everyone, it is not only energy-saving, long life, but also environmentally friendly, more beautiful colors, is a commonly used lamps for home decoration. In automotive lighting, LEDs have also been used for some time, but until now, there have been few models with full LED lights. So we will be very confused, what is the effect of the full LED headlights? Will it be the future of car headlight development in the future?
Introduction to the history of car lights
From the day the car was born, lighting is an important issue in the safety of car driving. The earliest lights were incandescent lamps, and later halogen lamps appeared, then to xenon lamps. The latest technological achievement is the LED light.
The earliest incandescent lights were subject to the life of the tungsten wire and needed to be replaced frequently. Later, in order to improve the service life of incandescent lamps, people added halogen substances such as iodine or bromine to the bulbs, which became a commonly known halogen lamp.
What is color temperature?
Later, it was discovered that the inert gas æ°™ can emit a dazzling arc light under the excitation of high voltage electricity, and can increase the color temperature value of the light, and let the lamp emit white light similar to the sun. After the Philips company's 5 research, car Xenon headlights came out. At present, xenon lamps have gradually replaced halogen lamps with their low power consumption and long life.
The scientific name of LEDs is light-emitting diodes, which are not really new objects. LEDs are used as indicators in many areas. In the field of automotive lighting, due to the fast response of LEDs, it was first applied to brake lights. In order to let the driver of the car behind the tail know the driving condition of the vehicle ahead, and reduce the occurrence of the rear-end collision. With the development of technology, high-brightness LED lights have been invented. This also provides a technical guarantee for the LED light to become a car headlight.
Analysis of luminescence principle
The xenon lamp consists of a starter, an electronic ballast and a helium gas sealed in a glass tube. Exciting xenon illumination requires the starter to boost the 12V low voltage on the car to a high pressure of 23000V, and then the actuator instantly loads the 23000V ultra high pressure onto the helium. In this process, once the power is leaked, it is easy to generate high-voltage fire and cause a fire.
The principle of LED illumination is quite different from that of xenon lamps. An LED is a solid semiconductor component. When these semiconductor materials are energized, only a portion of the electrical energy is circulated through the semiconductor material, and excess energy is released in the form of light, thereby directly converting electrical energy into light energy. There is no direct relationship between the brightness of the LED and the magnitude of the voltage. The 12V low voltage battery can drive the LED light. When the voltage applied to the LED is constant, the greater the current through the LED, the brighter the LED.
Lighting effect analysis
Currently, the brightness of a single LED source is still not as good as that of a xenon lamp. In most car lights, the LED is just the supporting role of the xenon lamp. Even high-brightness LEDs require multiple sets to release the brightness of a xenon lamp. The cost and heat generation of this group of high-brightness LEDs is much higher than that of xenon lamps.
However, the manufacturer said that through some special electrical conversion devices, LEDs can emit light of different color temperatures. Daytime running lights made up of LEDs. The color temperature can be converted under certain conditions to act as a fog light.
LED car light future prospects
At present, LEDs and the like have been widely used as automobile auxiliary lamps. LEDs have replaced other forms of light sources in many places such as turn signals and fog lights. However, because the cost and heat dissipation of high-brightness LEDs have always been a problem for developers, the main source of illumination for LEDs is still immature. If you can break through this bottleneck, the future of automotive lighting will be the world of LED.
