With the rapid development of the LED industry, LED constant current drive power supply and LED street lamp power supply and other related products are also favored by people, especially the LED street lamp power supply has a high power factor of up to 0.99, high reliability and long life. , in line with IP67 waterproof level; with over-voltage, over-current, over-temperature and short-circuit protection, optional constant current and constant voltage, with lightning protection design and other advantages, it has become a new favorite in the LED lighting industry. However, in the practical application of LED street lamp power supply, it is very necessary to know how to prolong the service life of LED street lamp power supply, so how to improve the service life of LED street lamp power supply?
1. Replace the electrolytic capacitor with IC: the lifespan is 10 times that of the original LED driver, and the lifespan can reach more than 40,000 hours, which can completely match the lifespan of the LED lamp
, and this solution is simple in design and small in size, only the area of the original LED driver. Forty percent, this solution is mainly used in household low-power lighting, and the applicable range is 3W ~ 20W.
2. Electronic components: The life of the LED street light power supply depends largely on the electronic components. If the component selection is good, it can basically be considered as the life of the lamp. Another key issue is the use environment of the power supply, such as: high Low temperature, large dust, and large fog all determine the length of the life of the LED street light power supply.
3. It is necessary to use a good capacitor or IC, and secondly, to solve the problem of heat dissipation: the temperature of the working environment is the key to the life of LED street lamp power supply, and the strict control of the working environment temperature of the power supply is inseparable from the successful use of insulation and thermal conductive materials. , Improving the thermal conductivity of thermal conductivity and insulating materials can double the life of the LED street lamp power supply.
