The invention discloses a radio frequency module application-based LED system, which comprises a transmitting party, at least one receiving party, an RF communication module, an LED dimming drive and an RF hopping selection random channel, wherein the receiving party comprises a micro control unit; the transmitting party and the at least one receiving party build wireless connection through the RF hopping selection random channel; command data transmitted by the transmitting party are wirelessly transmitted to the micro control unit of the receiving party through the RF communication module; the micro control unit sets two paths of PWM duty ratios according to the received command, and transmits information to the LED dimming drive; and the LED dimming drive is connected with an LED lamp and dims the LED lamp. The invention further discloses a dimming method for the radio frequency module application-based LED system. The utilization efficiency of communication by a radio frequency module is improved; the communication efficiency and accuracy are improved; and the energy-saving effect can be achieved.
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.
