LED optical wireless network as long as the lights

[oodzdr49]

led drive power of life and the life on the very match, it is difficult to play a long working life of led lighting advantage.flashing boardshis is why the industry has been active in the recent development of non-electrolytic capacitor of the main drive power led lighting. so why must use electrolytic capacitors? this is because the led is the dc current-driven devices, when ac power is turned on, the general is the use of components and smoothed rectified dc stabilized power supply circuit, the smoothing circuit is necessary because of the electrolytic capacitors ambient temperature and self-heating rise
output capacitor uses two about 5μf the mlcc. ac100v and 200vinput voltage to support two. it is understood that, under normal circumstances,multi-color sign board the capacity mlcc can not fully absorb the pulsating current, but by improving the control of d-side will not feel the lighting flicker. non-insulated main circuit buck, do not set pfc (power factor improvement) circuit.
