In recent years, China’s rapidly growing semiconductor lighting market, in particular, in April 2009 issued by the Ministry of Science and “agreed on launching the” City of ten thousand ten “pilot semiconductor lighting application engineering Reply” file, it is the LED Display in the application of road lighting to a new climax. However, the industry in high-speed development, some problems inevitably occur. Shanghai street before construction management center Wang Xiaoming, Director pointed out that there are too many companies keen on LED lighting technology will be applied to road lighting, whether traditional or non-traditional street lights business enterprises, resulting in the development and production of LED Lighting in the a series of large and small problems and defects. If these problems can not be a good solution, in practical applications, LED lights will encounter more resistance and questioned the objective, including the operation and maintenance of street lights from the management unit. In summary, LED lights enterprises in production and promotion of research and development applications, should focus on four main issues: first, the shape lamp structure. The shape of the traditional street lamps, such as sodium light fixtures, lighting and appliances are generally divided into two parts, specific to each product may vary, but generally speaking, basically similar. However, the special LED light source, the distribution of light in different ways, LED Tube are the shape can be described as great variety, many of them lights can not meet the operation requirements of shape, and even some companies is the standard used in outdoor lights indoors. In addition, LED lamps and also problems connected poles, almost all of the LED lights are fixed to the screw orientation, there is little hoop bolt. Links may be simple to install, so manufacturers of spending a little effort. But for running units, safety is the foundation, lighting lamps connected directly related to safe operation, so the degree of attention to it even more. Followed by the light weight of the problem. Light weight is important, but no such general awareness of LED manufacturers, or did not do too much to consider in this regard. Thermal Considerations for LED lamps, lamp shell relative to traditional lighting, the weight may be more important. However, the weight of heavy operation and maintenance would be some impact. The third part is the lighting problem can be replaced. LED downlight components generally have the power (drive) and the lamp housing several parts. Perishable main components are: power (drive) and the chip. In general, LED lamps can not replace the chip, power supply (drive) can be replaced, however, some products power (drive) is not enough to facilitate the replacement, or replacement in the field to spend too much time. In addition, the current LED lamp life of 30,000 hours is generally the longest 5 million hours. If the LED chips can not be replaced, when it can only replace the entire lamp, resulting in greater waste. The fourth is the power (drive) the life issues. Power (drive) is the LED lamps are key components. Because many manufacturers of power LED lamps (drive) is not their own production, and sometimes the quality of LED lighting good about themselves, they often inadvertently stumble in the power supply (drive) out of the question above. In fact, both the LED itself, the quality or life, or power (drive) the life of LED lights are the embodiment of quality and life itself, LED lighting quality assurance should also include these two aspects, namely, LED lamp life of 3 million hours Ye Hao, 50,000 hours Ye Hao, should include the power (drive) the quality and life. Can is currently on the market, the general LED lighting LED chip manufacturers are the only guarantee of quality, power supply (drive) life is a different matter. What manufacturers generally guarantee for 2 years in the majority, three years less, 5 years is too little. Thus, the current development of LED spotlight there is a new bottleneck – the power (drive), which restricts the quality assurance of the development of LED lights. This should arouse the concern of manufacturers.
