China LED driver power supply rainproof power supply manufacturer major challenges they may face is to find a low cost AC / DC drives, to meet to achieve more stringent power factor and efficiency of the performance of low-cost power system. Future, using high-quality, high-reliability power in space-constrained and there is difficulty cooling systems (such as LED lamps) will no longer be free. However, many end-users in a paragraph before the lamp life of 10,000 hours, in order to prove its high quality is quite difficult. Fan power supply fan bearings on the market, its bearing a total of three categories: oil-bearing, single ball (ie oil and ball), double ball bearing. Ball advantage lies in its long life, low heat while their own power suppliers Shaanxi LDE rain, low noise power wholesale Shaanxi LDE rain, relatively stable. The oil-bearing after prolonged use, including volatile oil, bearing wear, the latter noise will be great, life is short. Resolution is oil bearing or ball bearing, the easiest way is to manually toggle the fan power LDE rain, with the same strength, rotating ball to be easier, rotation time is long, and in came to a stop slightly in the opposite direction will turn about; and oil-bearing is obviously not the same.
