LED DRIVE CIRCUIT |
摘要 |
An LED drive circuit includes a rectification circuit configured to rectify an alternating-current voltage that is input via a dimmer circuit, a delay circuit having a switch, and a light emitting unit including an LED array including LEDs connected in series, wherein the delay circuit turns on the switch when a predetermined time elapses after the alternating-current current is input, and the rectification circuit and the LED array are directly connected when the switch is on. |
