informaciones en detalle
Power LED Bulbs 1. dedicated low-power LED constant current driver for 5MM straw hat lamp Yihuo low-power SMD LED, the maximum current of 80MA, string and can be used. 2. MOS integrated with professional management of the switching power supply chip production, the efficiency of more than 0.9, good stability, lines mature, mass production of LED bulbs used in the ranks, customers can rest assured that use 3. The drive circuit for the buck, the input voltage For the 160-260V, 220V is the dedicated drive, wide input range, output smoothing DC current, pulse small, little damage to the LED. 4. Driving LED approach: that is to string together, and, generally speaking, this section drives, the maximum output voltage is 150V, the minimum limit on the maximum output current of 80MA, the minimum limitation, so the number of stars should be driven To determine their own drive to be used, usually following a string of 50 driver, 50-100 for the two strings and three strings, 100-150 for the three-string, or four strings, in short, to meet the total current maximum 80MA, the total voltage More than 150V, the total power is not like no more than 8W request for it. 5. Power factor: this drive is an ordinary capacitor filter circuit, there is no power factor correction, power factor generally between 0.5-0.7.
