Solar LED street lamp, the design is difficult to limit the main road

LED lamps in the construction cost than traditional street lamps in expensive, energy-saving advantages, in 2008 national demonstration project has been published, in order to improve energy efficiency, combined with the solar LED street lamp design has become a new design and application. However, the industry pointed out that in the design of the cost and wind resistance and other factors, the number of supply of LED street lamp combined with solar design is limited, the park will be the main landscape lighting or auxiliary lighting.

Because the solar energy and the LED lamp source all adopt the direct current, compared with the existing household electric light source with alternating current, the combination of the solar energy and the LED lamp source can not be affected by the current conversion. It is understood that Taiwan is expected to be launched in 2008 with the LED solar street bidding plan, early demonstration Street project is scheduled for completion in July, the LED street lamp with solar power settings in the future will be the more than and 20 Taiwan office.

LED industry pointed out that the current application of solar LED street lamp is still a lot of design restrictions. Because of the high cost of solar panels, to the LED lamp, if the solar panel area will lead to the drag problem, so LED and 1 more than 4 Watt Solar hundreds of the most appropriate, is a 25 Watt LED lamp collocation 100 Watt Solar panels, will play a good effect to charge. Due to the number of LED street lamp is not high, compared to the current major roads need to use 100 watts ~150 watt LED street lamp, solar LED street lamp is still dominated by auxiliary or secondary roads.

At the same time, the industry also said that the combination of solar LED street lamp is suitable for high sunshine areas. In the Taiwan area, in the case of adequate sunlight, solar panels can maintain continuous use of 3~5 hours in 12 hours.

At present, the development of solar photovoltaic technology in Taiwan has accumulated a wealth of technology, the future of LED street lamp and further combined with solar photovoltaic, will help the development of Taiwan LED industry.
