Why the led driver is the key to the led lamp, such as the led mining lamp

Led mining lamp, project-light lamp, street lamp, Led lighting lamps and lanterns is in addition to the before mentioned Led chips, there is a key part is the Led driver, can say in the Led lighting lamps and lanterns, if the Led chip is a foundation, so the Led driver is the key to the whole lamp, because in the

in addition to the light emitting diode chip, the Led mining lamps, projector lamp, street lamp and other Led lighting lamps and lanterns is also a key component, the light emitting diode driver. Can say, in the led lighting lamps and lanterns, if the led chip is a foundation, so the led driver is the key of the lamps and lanterns. Because in the whole system, led drive power is more complex, more need to solve the problem. This is also lead to industrial and mining lamps, street lamp, projection lamp and other led lighting lamps and lanterns of the failure of the most key factors. According to incomplete statistics, the lamps and lanterns of failure more than 80% is due to the failure of the led driver. Therefore, reasonable choose led driver is the key to the correct selection of led lights. This is also affect the led industry and miner's lamp, street lamps and other lighting equipment cost is an important factor of the main causes of led drive failure are: 1. Electronic components, anti-aging and capacitance integrated circuit components, circuit boards, etc. Have life, the aging. Different quality price difference. 2 cooling structure of light emitting diode drive electrical components are very sensitive to temperature, especially the electrolytic capacitor. Formulas for calculating the service life of electrolytic capacitor used is 'for every 10 degrees below, will double service life'. Bad heat dissipation can greatly shorten the service life and lead to premature failure, resulting in light emitting diode drive failure. Especially for the built-in power supply ( In the power of the lamps and lanterns) , calorific value of power supply can increase the thermal conductivity and thermal stress of the lamps and lanterns, and the temperature of the led lamps and lanterns will rise, causing the lamps and lanterns of efficiency and significantly reduce the service life. 3 the product design. Design the product, should consider the good heat dissipation, and electronic components matching and consistency of driveway lights. There is no need to pull the car is very small, there is no need to use lots of materials on the tractor and abandoned the BMW engine. Consideration should be given the choice of power device, heat balance, surge protection and lightning protection. 4 process design and product quality control. Good product design also need excellent production techniques to achieve good effect, also need to ensure strict quality control system. In this respect, should pay special attention to the problem of solder joints, especially in manual welding more solar street light products. The main functions of the solder joint is the realization of electronic components and mechanical and electrical connection between the base board ( Is the goal of the led power supply printed circuit board) 。 Solder joint quality serious influence on the reliability of the light emitting diode drive and longevity. On the one hand, the solder joint failure from the production and assembly for welding, such as solder bridge, virtual welding, the phenomenon of empty hole, Manhattan. On the other hand, in use process, when the environment temperature changes, due to the different thermal expansion coefficient between components and printed circuit board, in the solder joints can produce thermal stress. Periodical change of stress can lead to solder joint fatigue damage, eventually leading to failure led driver. In order to guarantee product quality, yue photoelectric technology co. , LTD. Shandong heart preference Wei Ming, alum, philips and other quality stability of the domestic leading professional manufacturers of brand-name drive power supply. To ensure product quality and using effect.
