The failure cause of LED courtyard company street lamp light

Product is a new type lamps and lanterns, solar street lamps compared with the ordinary courtyard lamp, LED garden light much smaller failure rate, but does not mean no, so what are the failure cause of LED garden light? 1, poor quality of construction, due to construction quality



product is a new type lamps and lanterns, solar street lamps compared with the ordinary courtyard lamp, LED garden light much smaller failure rate, but does not mean no, so what are the failure cause of LED garden light? 1, the poor quality of construction for construction quality caused by the fault for a larger proportion. Main performance: one is the cable trench 【 In cable trench is to change electric power or telecommunications cable laying and facilities of the underground pipeline, palisade structure is also been laying cable facilities, such as rectangle, circle, arched pipeline structure. 】 Depth is not enough, sanding brick construction according to the standard; 2 it is aisle pipe production and installation does not conform to the requirements of both ends not made syndromes according to the standard beep mouth; Three is cable when the shop is dragging on the ground; Four is not in accordance with the requirements of standard construction is the foundation of embedded pipe, refined classification is mainly embedded pipe, coupled with a certain amount, difficult in cable, in the base at the bottom of the 'dead turn'; Five is the line nose and the thickness of insulation wrapped pressure is not enough, after a long run would interphase short circuit. 2, material don't pass it from years of treatment failure, material quality is low and there is a big factor. Main show is: less wire containing aluminum, lead is hard, thin insulating layer. 3, form a complete set of engineering quality is not good garden light cable generally spread on the sidewalk. The pavement construction quality is poor, ground subsidence, the cable force deformation, cable sheathing. Especially in northeast China Northeast China, is a geographical cultural regions and economic regions of China, is not administrative region; The word 'northeast', originally found in the rites, fang '. 】 In the alpine zone, winter arrived, the cable and the soil to form a whole, once appear subsidence, ground will be a tear at the bottom of the garden light foundation, and the summer rainfall, will burn out in basic root. 4, design is not reasonable on the one hand is overloaded. With the continuous development of city construction, garden lamp also extends continuously, the new garden light often near which courtyard lights, which received circuit, combined with the advertising career developing rapidly in recent years, advertising load were accordingly on the garden light, garden light load is too large, cable line nose overheating, heat, insulation, grounding short circuit, and so on and so forth. Lighting design, on the other hand, when only consider oneself circumstance of light pole, ignore the cable head space, cable head wrapped well, mostly even doesn't close the door, sometimes the cable length is not enough, joint production does not conform to the requirements, the causes of failure.
