On the quality and stability of LED outdoor lighting trends are key to success

Due to energy saving and carbon reduction consciousness rise, the world set off a wave of LED, both in the technology and application of backlight or illumination, is the focus of attention, and the related lighting application part, belonging to the national infrastructure construction and the use of LED lamp cloth speed condition is of concern, compared with the traditional street lamp, LED has energy saving and environmental protection, high efficiency and high stability and other advantages, but under the cost and weather condition, the quality requirement is very important.

LED street lamp set to promote the popularity of LED pioneer

With the progress of the LED industry, the difference between the cost and the traditional lighting will become smaller and smaller, so how to maintain a stable lighting quality in a harsh environment has become the key factor. From the current application around the point of view, LED lights in the overall popularity is still a way to go before, in addition to enact laws and regulations and related policies, related process, power management and cooling technology is the industry is rapid, but had to admit, LED industry is indeed the most dazzling star.

The LED lamp radiator, mainly to the cooling system more competitive

How to integrate the heat dissipation module and LED, will be the focus of future outdoor lighting projects

Looking at the global LED lighting policies and related laws, almost all the planned schedule is about to start in 2012 to stop using incandescent light bulb with LED lighting, LED lights with the policy factors will therefore bear the brunt, will begin to fully replace the traditional lamp. In addition, the mainland government before the Ten City million plan to expand to the current fifty city two million, and some European and American awards and subsidies, such as subsidies, can be seen in the determination of governments.

LED lamp winning key quality uneven in quality

The quality problem of LED lamps as the focus, in Taiwan in the past 3 years to build more than 20 thousand LED road lamps, according to the Survey Research Institute, there are about 1 million 700 thousand street lamp demand, although once triggered the industry price competition, but because the current around LED street performance quality is not a great difference, so many of the problems found in after the actual installation of LED street, the average failure rate as high as 8.2%, for infrastructure construction, this quality is not stable enough, the problems include power management and control, heat treatment, waterproof design etc..

The design of heat dissipation module is the key factor of LED quality

Chuan Xiang micro motor marketing center marketing department project manager Wang Baitao said, because the LED street lamp or outdoor lighting applications are high brightness and high power LED applications, if the design of the heat dissipation module does not take into account the characteristics of the environment will be because the heat caused by poor decay, and affect the overall use of life, even the climate factors (lightning, typhoon, frost, snow and so on) must be considered in the overall design details, so the "," domestic trouble and foreign invasion "radiating module design" will be the main key technologies.

LED lamp cooling method is generally divided into active cooling and passive cooling (whether to need to drive additional energy to dissipate the heat as the main difference), and in the use of outdoor lighting and large LED on the active cooling air cooling radiator (fan) is competitive, with diversion effect itself, and the use of air in between heat exchange, take the accumulation of heat, to achieve "forced convection cooling mode".

The current cooling requirements of the fan is still the mainstream

Commitment to the above, the current LED street lamp cooling, mainly in the price and performance of the fan is more competitive. The current use of the fan as a heat sink module will often have several considerations: size, air flow direction and the overall design, noise and fan failure rate, etc.. Wang mentioned, outdoor LED lighting or to consider changes in the environment and design a heat dissipation module suitable is the appropriate solution, the temperature difference between day and night some high places, or snow, dust and various environmental factors cannot be controlled, must be deemed to affect LED for efficiency, and to overcome.

Wang pointed out that the transfer of micro motor in a few years ago has successfully entered the LED street lamp market, and the application of a number of international road signs in the case, so the fans in the LED application technology has been very mature. Apart from the sophistication and fan drive motor in the performance itself bearing material on the promotion, is the future direction of Chunxiang towards high life, low noise and high reliability in advance, outdoor and high power LED lighting applications, or to rely on the overall design of the heat dissipation module, collocation LED through the ordeal in the external environment, this is one of the largest key breakthrough, believe that the popularity of LED generation is coming.

Future market prospect of LED street lamp

According to industry estimates, replace traditional mercury lamps in Taiwan in LED street, will save 9 million 800 thousand of electricity per year results, although the Energy Bureau in 2011 the Ministry of economic is the efficient implementation of street subsidy programmes, but it is pointed out that the government is not specific for LED street to grant program, so the LED industry mostly exported to Europe and the United States and the mainland market. And compared to 350 thousand in 2010 2011, LED street lamp, market size will reach 500 thousand units, although it is currently in the state but after the contention of a hundred schools of thought, and the elimination of competition in recent years, various manufacturers location will gradually become clear, and the market will rapidly expand.
