SEHOLD HOME LED-AV LED-220VAC

The working principle of AC LED light source The working principle of AC LED light source will be a bunch of LED micro-die staggered arrangement of the matrix process were divided into five strings, AC LED string composed of grains similar to a bridge rectifier, rectifier bridge connected the two ends of the respective AC power, and the other join both ends of a string of LED die, the positive half-cycle alternating current along the blue path flows, 3 strings LED crystal light, the negative half-cycle path along the green movement, another string of three light-emitting LED die, four bridge arm of the LED crystal grain turns luminous, relatively the same time, the bridge arm of the LED die light in the middle string of LED die has been a result of shared use of light. Will be in the 60Hz AC frequency of 60 times per second rotation lit. DC bridge rectifier is a pulsating direct access to, LED's light is flashing, LED light, there are power outages continued afterglow characteristics, afterglow can maintain tens of microseconds, because the human eye on the flow-spot memory is inert, and The results of the human eye on the LED light source light-emitting + afterglow mode of operation is continuous in the light reading. LED there is half the time at work, half time break, so heat can be reduced 40-20%. Therefore, the life of AC LED longer than the DC LED.
