Solar street light specification _ _ Ou solar street construction in Nanchang, Jiangxi Solar street light provided by the EU can Optoelectronics Technology Limited. Nanchang Ou Optoelectronics Technology Co. (www.okled.cn) is specialized in the "solar lights, wind and solar lights, solar garden lights, solar lawn" of the enterprise, the company of "honesty, hard service" concept, for you provide the highest quality products and services. Welcome to inquire! Contact: Liu. Optoelectronics Technology Co., Ltd. Nanchang Ou main products are: solar lights, solar garden lights, solar lawn lights, solar wind hybrid street light series; a variety of LED light sources, solar PV modules, batteries, controller; various lampposts, patio poles, waterproof box and supporting the use of flip-flops, light control when the control switch and other electrical products. Solar lighting products are green, safe, energy-saving features solar street lamp Why use a constant-current source, the characteristics of LED lighting material determines its large environmental influences, such as elevated temperature solar home light how much the LED current will increase to increase solar lights, voltage, LED current will increase. Long-term than the rated current, will greatly shorten the life of the LED lamp beads. And that is when LED constant current and voltage changes in environmental factors such as temperature, to ensure that their current value unchanged. 2, solar street lighting power supply current precision: some precision constant current power supply on the market is poor, as the popularity of the recommended programs constant program error of ± 8% solar street much money, constant error is too large. ± 3% generally require it. 3% of the design. To fine-tune the production of power in order to achieve ± 3% error. 3, the power supply voltage of the solar street light: LED general recommended voltage is 3.0-3.5V, has been tested, mostly in 3.2V, 3.2V is calculated according to the formula so reasonable. N-series lamp beads total voltage = 3.2 * N. 4, solar lights power supply current is how much is the most appropriate: for example, the rated current of 350 mA LED, some plants used to make the outset, designed 350 mA, in fact, the current very serious fever, the more second comparison test, designed to 320 mA is ideal. 5, series-parallel solar street with wide voltage power supply board to be more wide-do: make LED solar street light power supply input voltage range of relatively wide range AC85-265V, the LED lamp series and parallel plates is very important. Optoelectronics Technology Co., Ltd. Nanchang Ou main products are: solar lights, solar garden lights, solar lawn lights, solar wind hybrid street light series; a variety of LED light sources, solar PV modules, batteries, controller; various lampposts, patio poles, waterproof box and supporting the use of flip-flops, light control when the control switch and other electrical products. Solar lighting products are green, safe, energy-saving features. Solar garden bug fixes for most people to use solar garden lights, solar garden lights are ideal for people living electrical products, solar garden lights, solar street lights without using wires specifications, no trenching works, very convenient. But with the passage of time and life, the solar garden lights and ordinary street will be a problem, in the end is what causes the failure of solar garden lights it? Solar courtyard failure mainly to solve the problem of solar garden light construction and materials. Solar garden lights in the building, many manufacturers, because the market needs of solar garden lights, so a reduction of product procurement, LED street light faults, mainly in the high hardness, thin insulating layer. Solar garden lights in the building, mainly due to substandard quality, due to the relatively large proportion of failures, mainly reflected in an unstable foundation installation, do not follow the standard installation construction requirements, resulting in failure of solar garden lights.
