Since 1879, Edison invented incandescent lamps. For more than 120 years, the principle of electric light source technology has experienced three main stages: the principle of thermal radiation, the principle of gas discharge and the principle of solid electroluminescence, and the products of the previous two types of illumination principles are dominant, including incandescent Electric light source products such as lamps, low-pressure discharge lamps, tungsten halogen lamps, high-pressure sodium lamps, metal halide lamps, and trichromatic fluorescent lamps.
HID lamps have not appeared in the global market for a long time. Since the earliest application of the new Mercedes-Benz E-Class sedan in 1995, more than 5 million vehicles worldwide have installed HID lamps, which are listed as high in Europe, Japan, Korea and other places. Standard and equipped for performance and safety. At present, the global market for HID lamps is monopolized by companies such as Philips, Osram, and GE Lighting. In China, a small number of companies have begun to focus on the field of HID lamps, such as Shanghai Yaming and Foshan Snowlight.
HID lamp has the characteristics of energy saving, high luminous efficiency, long life, good color rendering performance, etc. It can give the driver a wider field of view, double the illumination, plus better light intensity distribution on the road surface, and the life expectancy of the car. It also eliminates the trouble of replacement and lowers the cost of use, and the light color is close to daylight. All of these have a significant improvement in safety improvement and comfortable driving, and Xenon metal halide lamps are 10 times longer than tungsten halogen lamps, and vehicle power is reduced by more than half, and it is beneficial to reduce the incidence of night traffic accidents. It is a traditional halogen lamp. The best alternative. According to a sample survey conducted by Shell, the current market share of Xenon metal halide lamps in the Chinese market is less than 2%, which is estimated to be less than 5% worldwide. China's automobile industry is in a stage of rapid development, which brings great opportunities for the development of automotive xenon metal halide lamps.
HID market has broad prospects
According to the 2004 automobile production statistics published by the Korea Automobile Industry Association, the global automobile production in 2004 was 64.16 million, of which the first in the United States, the output was 19.965 million; the second in Japan, the output was 10.51 million; the third in Germany was 55.565 million. Vehicle (Source: China Auto News on February 21, 2005), and in 2005 the global car ownership has reached 800 million.
In 2005, China's auto sales of 5,758,200 domestically produced vehicles and imported automobiles were 160,000. The annual capacity of China's auto market reached nearly 5.92 million, ranking second in the world, second only to the United States. According to the prediction of China Association of Automobile Manufacturers, China's automobile production and sales will increase by about 12% in 2006 to around 6.4 million units. In 2005, the number of car ownership in China was about 35 million, and the number of cars in 2010 will reach 60 million. The proportion of Xenon metal halide lamps installed in Chinese cars is lower than the world average, and the market space is huge.
At present, the global market capacity of HID lamps is about 7.5 million, of which PHILIPS has a capacity of 3 million, and the remaining market share is shared by Japanese and Korean companies. In contrast, the penetration rate in the domestic market is even lower, and China is also the fastest growing market for global automobile production and sales. According to the configuration of two headlights in one car, the demand growth rate in the Chinese car lamp market will be Will be much higher than the growth rate of automobile production and sales. This will provide a very broad market development space for domestic marketers of HID.
From the 1995 new Mercedes-Benz E-Class sedan, the first application of Xenon metal halide lamps for vehicles, more than 5 million vehicles have been installed in the world, and Xenon metal halide lamps have been installed in Europe, Japan, Korea and other places. Automotive lighting products will become the necessary assembly for cars after the ABS brake system and airbags.
In fact, metal halide lamps are not limited to automobiles, and have a wide range of applications in commercial display lighting, industrial special lighting, and medical lighting. The color commercial display metal halide lamp, short focal length concentrated metal halide lamp and medical endoscope (fiber source) metal halide lamp developed by the company have good market prospects.
Due to the high gross profit margin of Xenon metal halide lamps for vehicles, many enterprises have invested in production in China. The main equipment gloves are basically imported from Germany. Except for Japanese and Korean companies, the output of other enterprises is not large, and both After entering the automobile, the market is often loaded with the increase of investment, and the competition for the automotive Xenon metal halide lamp market will become fierce.
The market entry threshold is relatively high
Xenon metal halide lamps for vehicles are high-tech products in high-intensity discharge lamps, which require extremely pure raw materials and superb process technology. At present, only a few companies such as Philips, Osram, GE Lighting and the company have mature technology and related patent protection for automotive helium metal halide discharge lamps. At present, there is no complete set of complete production equipment for vehicle helium metal halide discharge lamps. The main equipment for the production of the company is imported from abroad and independently developed related equipment. In the second half of 2004, the company's first set of Xenon metal halide lamps and electronic ballasts were introduced. The main technical indicators of the products reached the international level. Advanced level, and production costs are far lower than similar foreign products.
The market for vehicle Xenon metal halide lamps is divided into two parts: the whole vehicle and the auto parts. From the competition of this product, the main competition comes from Philips and Osram. Philips' Xenon metal halide lamps are concentrated in the vehicle supporting market. The auto parts market is relatively rare and expensive. The production and market of Xenon metal halide lamps for early vehicles are almost exclusively monopolized by Philips, and they are protected by multiple patents. product. Osram's automotive Xenon metal halide lamps are of high quality. Currently, they are only found in the domestic vehicle supporting market. The products of the company are growing rapidly in the auto parts market and have obtained two certifications (ISO/TS16949 and E- into the vehicle market). MARK certification), after continuous improvement of production and continuous improvement of quality, has already entered the conditions of the vehicle market. The company's automotive Xenon metal halide lamp has a complete system of intellectual property protection. The lamp's external structure is different from Philips' patent and its performance parameters are excellent.

HID is the abbreviation of High Intensity Discharge. It is understood from the literal meaning that it is a high-pressure gas discharge lamp. The real HID gas discharge lamp, like the fluorescent lamp group, must have a transformer. Its light-emitting principle is to use positive and negative electricity to stimulate xenon and rare. The metal chemical reaction glows, so you will find a small glass ball in the tube of the HID bulb. This is filled with helium and a little rare metal. Just use current to stimulate them to react chemically. Will emit light up to 6000K color temperature, how to use current to stimulate them for chemical reaction? First, boost the 12V voltage on the car to 23000V. When it is just turned on, it will strongly stimulate the helium to quickly reach high brightness, and then turn the voltage into 8000V, and stabilize the continuous supply of Xenon bulbs! The light of 6000K color temperature is the luminosity of the traditional halogen lamp, and it is also the color temperature closest to the noon daylight, and the luminosity that is most comfortable for the eyes. In addition, because the activity of helium molecules will become more active as the use time is longer, the gas discharge bulb will be brighter and brighter!
Specifically, the advantages of xenon lamp safety over halogen lamps are reflected in the following five aspects:
One is brightness. The brightness of HID is unmatched by tungsten lamps, which can provide color temperature close to noon daylight. Second, the long life is long. Since the filament is not used, the filament of the original bulb is not used. Only this point increases the life of the HID by nearly 10 times and can be used for about 2,000 to 3,000 hours. The third is energy saving, because the current is used to stimulate the inert gas for chemical reaction, but only when the power is turned on, it can save half of the energy compared with the halogen lamp. The fourth is safety. This is also the biggest advantage of HID. It is reflected by the used owner. HID makes the line of sight clearer and the safety of night driving is guaranteed. It is mainly because the inert gas reacts and the intensity is up to 6000K. The color temperature is bright, the color temperature is close to the white sun, so the safety is unquestionable. The fifth is emergency. Because of the different illuminating principles, the chemical reaction of the inert gas will not be extinguished immediately due to the problem of the battery's power supply, thus giving the driver a little emergency time.
