Abstract

The invention discloses electronic equipment based on direct current supply communication and a control method of the electronic equipment. The electronic equipment comprises a power supply and a controlled device, wherein the power supply comprises a power supply conversion module, an on-off switch and a modulation module; the controlled device comprises a demodulation control module, a driving module and a load; the power supply conversion module and the modulation module are connected with the on-off switch; the demodulation control module and the load are connected with the driving module; the on-off switch is also connected with the driving module through a power line; the demodulation control module is connected with the power line; and the modulation module controls the on-off time of the on-off switch according to external remote control commands, so that the remote control commands are modulated into corresponding control signals according to the on-off time, the control signals are sent through the power line and then demodulated by the demodulation control module according to the on-off time, and adjustment of the working state of the load by the driving module is controlled. The electronic equipment is simple in structure, and the working state of the load can be adjusted accurately.

Description

technical field [0001] The invention relates to the control field of electronic equipment powered by a DC power supply, in particular to an electronic equipment based on DC power supply communication and a control method thereof. Background technique [0002] With the development of lighting technology, LED (Light Emitting Diode, light-emitting diode) lighting products have gradually replaced traditional halogen lamps and energy-saving lamp lighting products because they can be easily adjusted for brightness or color temperature. [0003] At present, MR16 spotlights are the main representative of LED lighting products, and the composition of such lighting products is generally composed of power transformers and spotlights. The power transformer converts 220V city power into 12V high-frequency AC power, and the converted 12V high-frequency AC power drives MR16 spotlights to emit light. For the MR16 spotlights that require dimming, in the prior art, the traditional thyristor ...
