Embodiment Construction
[0041] The present invention will be described in further detail below with reference to the accompanying drawings and examples, but the embodiments of the present invention are not limited thereto.
[0042] Realize the system structural block diagram of the present invention as figure 1 As shown, it consists of a rectifier control unit and an LED light brightness adjustment unit. The rectification control unit receives single-phase 220V AC power from phase line input terminal L and neutral line input terminal N, and outputs controllable rectification voltage from the first controllable rectification output terminal AC1 and the second controllable rectification output terminal AC2. The brightness adjustment unit of the LED lamp receives a controllable rectification voltage from the first controllable rectification input terminal AC1 and the second controllable rectification input terminal AC2 to control the brightness of the LED lamp.
[0043] The structure of the rectifier c...
