HID is the abbreviation of High Intensity Discharge, which is a high-intensity discharge lamp. The street lamp we see very bright yellow light is a kind of HID lamp (sodium lamp). Fluorescent lamps used at home are low-pressure (or low-intensity) gas discharge lamps.
Common HID lamps are HID nano lamps, HID mercury lamps and HID metal halide lamps (referred to as metal halide lamps). Metal halide lamp is the most promising high-tech product in the electric light source industry. It is the highest technical level of the electric light source industry and a very important lamp in high-intensity gas discharge lamps (HID). Due to its high luminous efficiency, good light color and energy saving, metal halide lamps are the first choice for green lighting projects. At present, metal halide lamps are mainly used in the field of floodlighting in stadiums, machine-taste stations, ports and urban lighting projects. With the development of metal halide lamps market and technological advancement, metal halide lamps will be widely used in urban roads and businesses. It is widely used in supermarkets and industrial and mining lighting, and has a very large market development space.
Metal halide lamp market analysis
In 2002, China's ordinary incandescent lamp output was 3.72 billion, with 750 million auto lamps, 870 million tungsten halogen lamps, 1.43 billion fluorescent lamps and 67 million HID lamps. In recent years, the structure of electric light source products has gradually become more reasonable, and the energy-efficient electric light source products have grown by a large margin, while the ordinary incandescent lamp products have basically maintained the original level. The fluorescent lamps and HID lamps have a large increase. The reason for the rapid growth of HID lamps is that the demand for domestic lighting market is growing, and the second is the increase in export volume. Among the HID lamps, high-pressure mercury lamps and high-pressure sodium lamps grew steadily, and the fastest growth was metal halide lamps, an increase of 40%.
According to the analysis of the research, the most influential metal halide lamp manufacturers in China include Shanghai Philips Yaming Lighting Company, Hangzhou Lighting Electric Company, Jiangsu Changzhou Pros Lighting Co., Ltd., Foshan Electric Lighting Co., Ltd. and other enterprises. These enterprises have introduced the advanced production technology software and complete sets of production equipment of American Innovation Light Source International Co., Ltd. The quality of metal halide light source products has reached the quality level of international similar products.
HID ballast
HID lamps are gas discharge lamps, so to light the lamp and work properly, a ballast must be used to work. This ballast is called a HID ballast. HID ballasts are available in both inductive and electronic versions. HID electronic ballast is a kind of electronic ballast, its circuit is more complicated, and the requirements are also very high. It belongs to the kind of electronic ballast with the highest technical content.
The electronic HID ballast is still limited to the small power field, generally 20-150W for a segment, 150-400W for the second segment, and 400W or more is basically the world of magnetic ballasts. Even in this small segment, the survival of electronic HID ballasts is not optimistic. There are three main reasons: 1. The technology is not mature, and it is listed without sufficient verification. 2, not based on the premise of reliability, low-cost competition, that the price is low, there is a common market 3, the lack of technical support of large-scale lighting manufacturers. Domestic electronic ballast enterprises are generally weak, and the smallest is only a few people. Electronic ballasts are not products that small businesses can “playâ€. They don’t depend on large-scale lighting companies, and it’s difficult to survive. The same is true for electronic HID ballasts for PHILIPS and OSRAM.
Metal halide lamp electronic ballast
Accordingly, there are two types of HID metal halide lamp ballasts: inductive and electronic. After nearly 20 years of efforts by experts in the lighting industry and the integration and specialization of some components, the technology of electronic ballasts for metal halide lamps has made great progress. However, the emergence of electronics does not mean that the inductor will disappear immediately. Because of the technology, quality, cost and service, in the field of HID metal halide lamps, the inductor still occupies the majority of the market share, despite the HID metal halide lamp market in recent years. Rapid development, electronic demand is also increasing, but in the field of metal halide lamp electronic ballast, there is still a long way to go. It can be said that this is an almost blank field, and the business opportunities are unlimited.
In the field of high-intensity discharge lamps, low-power metal halide lamp ballasts do not have an advantage in terms of overall operating costs. However, in some special lighting occasions with moving objects, such as table tennis halls, tennis halls, badminton halls, and photography and video recording occasions, electronic ballasts can be better because they have continuous dimming and can be strobed without stroboscopic. The ground replaces the halogen-filled tungsten filament lamp, so it has obvious advantages and is widely used.
But we also have to see another point. Metal halide lamp electronic ballasts have "potential advantages" in terms of small size, light weight, constant output, no stroboscopic, no noise, long life, energy saving, environmental protection and safety. Moreover, market changes are sometimes unimaginable, especially under the current global environmental protection and energy conservation trends, which may lead to geometric progression. This means that new technologies will surface at any time. Especially in the past two years, many enterprises have increased their investment in this area, and will also directly accelerate the rapid development of metal halide lamp electronic ballast technology. At present, the electronic core technology of metal halide lamps is still monopolized by PHILIPS, OSRAM and GE. With the further development of the market, it is believed that this "monopoly" will soon be broken.
Market prospects of electronic metal halide lamps
According to industry experts, metal halide lamps will be developed in the direction of low-power and ceramic metal halide lamps, with higher levels of production technology and automation equipment. It has been produced abroad, and the domestic research and development stage is still in progress. Domestic enterprises are expected to use this process technology to produce such metal halide lamps within 3 to 5 years. Nowadays, low-power metal halide lamps for indoor commercial lighting have exceeded at least 20% of the entire metal halide lamp market, and they are still growing. It is believed that within a few years, the proportion of indoor metal halide lamps will be comparable to that of outdoor fans.
The rise of an emerging industry is bound to be the result of the decline of the alternative industry. GE was originally the leader of the incandescent lamp industry and has now been replaced by the energy-saving lamp industry. From the beginning of the development of the first electronic ballast by PHILIPS, it is to replace the inductor, which is its mission, but also the requirements of energy saving and environmental protection. Therefore, it is not necessary to question the existence and development potential of electronic metal halide lamps with the domestic status quo.
According to statistics, the reconstruction of old cities and rural urbanization in the country, the construction of railways (metro, light rail transit) in major cities across the country, and the construction of highways across the country will take 30 to 50 years to complete. In particular, the holding of the Beijing Olympic Games will promote the development of stadium facilities in large and medium-sized cities across the country. The national airport transformation and port construction that are developing in parallel with the economy are all developing. All of these, under the global development trend of increasing environmental protection and energy conservation, will promote the accelerated development of the electronic metal halide lighting market.
Therefore, electronic metal halide lamps have a large space for development in China, and enterprises should seize this rare development opportunity.
