Problems solved by technology
There are many conversion circuits currently used, and the current provided to the control system is very small, which is sufficient for general control systems. However, after the system uses remote control dimming and adds wireless transmission chips, the power consumption of wireless transceiver chips is relatively large. Large, especially in order to ensure that the wireless signal has sufficient coverage, the operating current of the entire control system is required to be around 100 mA

An LED light source wireless dimming system comprises a mobile terminal with a WiFi module, a wireless router, a controller, a light modulator and an LED light source. The mobile terminal sends dimming control instructions to the controller through the WiFi module and the wireless router. The controller receives the dimming control instructions from the mobile terminal, and sends relative data to the light modulator in an infrared mode after analysis and conversion processing is carried out on the dimming control instructions. The light modulator receives infrared dimming control signals sent by the controller and carries out light modulating on the LED light source, and the light modulator feeds the light modulating state information back to the mobile terminal to form closed-loop control. The invention further provides an operation method of the LED light source wireless dimming system. According to the LED light source wireless dimming system and the operation method thereof, the WiFi technology is adopted, any intelligent equipment with a WiFi function can be used for controlling the LED light source wireless dimming system, multi point control can be carried out on the system, the controller can further be connected into a local area network to achieve remote control, and the possibility that the system can be connected in to the Internet is provided.
Description
technical field [0001] The invention relates to a wireless dimming system of an LED light source and an operating method thereof, in particular to a wireless dimming system of an LED light source controlled by WIFI and an operating method thereof. Background technique [0002] Two-wire dimmers have been widely used in places such as homes and corridors where the brightness of the light source needs to be adjusted. It can work normally only by simply connecting it in series between the light source appliance and the power supply. The dimmer functions as a passive Electrical switches. The power supply required by the electrical components in the dimmer is also taken from the circuit, and the required operating current also flows through the lighting source. [0003] In recent years, LED light sources have been increasingly widely used in low-power lighting, and in many occasions it is necessary to adjust the luminous intensity of the light source. Dimming technology has also...
