Abstract

The invention discloses an LED system based on the application of a wireless radio frequency module, which includes a sender, at least one receiver, an RF communication module, an LED dimming drive, and a random channel selected by RF frequency hopping. A wireless connection is established between the party and the at least one receiver by selecting a random channel through RF frequency hopping, and the command data sent by the sender is wirelessly transmitted to the micro-control unit of the receiver through the RF communication module, and the micro-control unit Set the two-way PWM duty cycle, transmit the information to the LED dimming driver, and the LED dimming driver is connected to the LED lamp and dimmed. The invention also provides a dimming method for the LED system based on the application of the wireless radio frequency module . The invention improves the utilization efficiency of the radio frequency module for its own communication, improves the communication efficiency and accuracy, and can achieve the effect of energy saving.

Description

technical field [0001] The invention relates to the technical field of semiconductor lighting, in particular to an LED system and a dimming method based on the application of a radio frequency module. Background technique [0002] At present, with the wide application of LED lighting, LED lamps with intelligent control functions have gradually been recognized by the market. In particular, the maturity of 2.4G wireless communication technology enables it to be used in large quantities in LED dimming control; it gets rid of the troubles of wiring of traditional wire control and the limitation of the directionality of infrared control. However, when all lamps transmit data under the same wireless channel, it will inevitably cause data congestion. In the application of lamps, the processing capacity of the processor used is very limited, so an efficient and simple wireless channel selection and switching method The proposal has important practical value.
