Several big trap you know several solar street light?

Solar street lights and LED street lights are urban development as an important lighting facilities, but now the solar street light lamp market price is differ, LED street lamp, solar street lamps factory product quality is uneven, a lot of reason is that in the Chinese market, LED street lamp factory

solar street light and LED street lights are urban development as an important lighting facilities, but now the solar street light lamp market price is differ, LED street lamp, solar street lamps factory product quality is uneven, a lot of reason is that in the Chinese market, LED street lamp, solar street light manufactory of patent consciousness is not strong, lack of innovative, industry price war factory unceasingly in the aspects such as material, process cost reduction, lead to the quality of LED solar street lamps have brought great bad influence, often see it dark street lamp use after a period of time, or a variety of problems. The street lights maintenance tougher for the outdoor high device, for street lamp management, unstable product quality makes the maintenance cost higher. Today high lamp factory is dedicated to all the purchasing solar LED street lamp pay attention to the analysis of five pitfalls. First, counterfeit chips, low-end chips LED lamps and lanterns is the most core chip, directly determine the performance of lamps and lanterns! However, some adverse manufacturers use customer unprofessional, from the cost of the above consideration, using low price chip, make customer buy the low quality of the product with high price caused a direct economic loss, and cause serious quality hidden trouble to LED lamps and lanterns. Shandong green valley of new energy technology used for the Taiwan import wafer chip, the United States imported pury chip. Second, configuration, qi, to exaggerate the configuration parameters of solar street lamps with price lower profits, also in the fierce competition also led to many solar street lamps factory started to cut corners empty mark product parameters, the condition of light wattage, wattage of solar panel, battery capacity, and even a solar light pole material, there is a problem. , of course, this also is the need customers repeatedly than price, low price, is also related to the practice of a few manufacturer. Third, thermal design, configuration, unreasonable cooling design, LED chip p-n junction temperature rise every 10 degrees, the service life of semiconductor devices will be faster. Due to the requirement for high brightness LED solar street light, the use of environment is harsh, if the cooling solution is not good, can quickly lead to LED aging, reduced stability. Other unreasonable configuration is often lead to specific usage can not meet the expectations of results. Fourth, as gold and copper wire controller problem many LED manufacturers trying to develop such as copper alloy, gold silvering alloy wire, silver alloy wire to replace expensive gold thread. Although these alternative is better than that of gold thread on certain features, but poor in chemical stability but many, such as silver and gold silvering alloy wire is vulnerable to sulfur corrosion/chloride/bromide, easy oxidation of sulfide copper wire. For similar to suction breathable sponge encapsulation of silica gel, these alternatives to make wire bonding are more susceptible to chemical corrosion, the reliability of the light source is reduced, use time grew, LED lamp bead are more likely to break the dead light. In respect of solar street light controller, the controller if there is failure, the process of testing and inspection, there will be a 'whole lights', 'is not allowed to turn off the lights when' and 'damage', 'individual die LED lamp bead light', 'the whole lights flashing virtual' phenomenon.
