Abstract

The invention belongs to the technical field of electronic circuits, and relates to an intelligent lamp and a color switching detection circuit and method thereof, and the intelligent lamp comprises a rectification filter circuit, a main power circuit, a power supply circuit, a wall switch detection circuit and a control circuit. The method comprises the following steps: after rectification processing and filtering processing are carried out on alternating current electric signals output by the power supply circuit, outputting direct current electric signals; detecting the state of the wall switch according to the level of the direct-current electric signal received in a preset time period, performing voltage conversion on the direct-current electric signal, obtaining the state of the wall switch, outputting a feedback signal, and finally performing power control on the direct-current electric signal according to the feedback signal; controlling a light emitting module to emit light or extinguish, and switching the color temperature of the light emitting module. Therefore, whether the wall switch is really turned on and turned off or not is correctly judged by adopting the detection mode, so that false detection is avoided, false triggering generated by detection waveform change is eliminated, and the effect of switching the color temperature of the light-emitting module is achieved.

Description

technical field [0001] The application belongs to the technical field of electronic circuits, and in particular relates to an intelligent lamp, a color-cutting detection circuit, and a color-cutting detection method thereof. Background technique [0002] At present, if the products (including lamps) for switching and cutting colors on the market are connected with a silicon controlled rectifier dimmer, the detection waveform of the switching machine will change, resulting in false triggering of color cutting. [0003] Therefore, the existing intelligent lamps have the problem of false triggering of color cut due to changes in detection waveforms of switching on and off due to dimmers. Contents of the invention [0004] In view of this, the embodiment of the present application provides an intelligent lamp, its color-cutting detection circuit, and a color-cutting detection method, aiming to solve the problem that the detection waveform of the switching machine is changed du...
