Abstract

The invention relates to the technical field of deep dimming circuits, in particular to a discrete component self-vibration type silicon controlled rectifier deep dimming circuit, a power supply input end is connected with the circuit through a silicon controlled rectifier dimmer to control an LED load light source, and the discrete component self-vibration type silicon controlled rectifier deep dimming circuit comprises an EMC circuit, a rectification filter circuit, a discrete component self-vibration circuit, a ripple smoothing circuit and a deep dimming circuit; the primary coil and the secondary coil of the transformer are respectively connected with the discrete component self-vibration circuit and the ripple smoothing circuit. The silicon controlled rectifier dimming circuit solves the problems that an existing silicon controlled rectifier dimming circuit cannot achieve good dimming depth, cannot support most silicon controlled rectifier dimmers in the market, is large in power frequency ripple, shakes and flickers in the dimming process and is high in cost.

Description

technical field [0001] The invention relates to the technical field of deep dimming circuits, in particular to a self-shocking thyristor deep dimming circuit of discrete components. Background technique [0002] Dimming circuit is to adjust the brightness of LED or light bulb. The implementation methods usually include: analog dimming, timer dimming, PWM pulse width dimming and thyristor dimming, etc. [0003] In the existing thyristor dimming circuit, it usually cannot achieve a good dimming depth, cannot support most of the thyristor dimmers on the market, the power frequency ripple is large, and the dimming process jitters, flickers and The problem of high cost. [0004] Therefore, a self-shocking thyristor deep dimming circuit with discrete parts came into being. Contents of the invention [0005] The content of the present invention is to provide a self-vibrating thyristor deep dimming circuit, which mainly solves the problem that the existing thyristor dimming circ...
