Problems solved by technology

At the same time, the existing switches used to control LED lamps are all manual switches that require manual operation, which brings great inconvenience to users.
The existing remote control switches used in lamps (including LED lamps) generally adopt point-to-point control and cannot control multiple lamps, and cannot change light and adjust colors, so they cannot meet the actual needs of real life.

Embodiment Construction

[0026] The aforementioned and other technical contents and features of the present invention are described in detail below with reference to the accompanying drawings.

[0027] refer to image 3 , for the present invention implements the main engine (remote controller) circuit schematic diagram, in image 3 The wireless radio frequency module IC1 adopts the nRF401 wireless transceiver chip launched by Norway Nordic Company. The chip uses the 433MHz ISM frequency band and is a real single-chip UHF wireless transceiver integrated chip. It includes high-frequency transmission, high-frequency reception, PLL synthesis, FSK modulation, FSK demodulation, multi-channel switching, etc. in a 20-pin chip. , is currently the most integrated wireless data transmission product. The radio frequency module uses an on-board differential loop antenna, and the load impedance of the antenna port is 380Ω.

[0028] exist image 3 The middle IC2 is the single chip microcomputer W77E58, its speed...

Abstract

The invention discloses a one-to-many master-slave mode LED illumination remote-control device which not only achieves a function of remote control of an LED lamp, but also employs a one-to-many master-slave mode for data communication between a master and an extension, wherein the master (a remote controller) is in charge of transmitting the address, a control command and scheduling of the extension (the LED lamp) and the extension is in charge of executing a command and returning data according to the requirement of the master. Because the same physical channel is used for transmitting and receiving, only one extension is allowed to be in the state of transmission at any moment. Only an extension which is called by the master can occupy a bus and response to the master. As a result, only one remote-control switch is required for controlling a plurality of LED lamps at the same time, separately turning on or turning off one of the LED lamps, and dimming one of the LED lamps separately. A wireless remote-control receiving device of the LED lamp and a power driver of the LED lamp are built in the LED lamp and enable a system to be installed more conveniently and have a more simple structure.

Description

technical field [0001] The present invention relates to a wireless remote-controlled LED lamp group and its control method, in particular to an LED lamp group and its control method controlled by a one-to-many master-slave mode wireless transmission signal mode. It relates to LED lighting technology, in particular to a remote-controllable LED lighting system. Background technique [0002] Due to the characteristics of high luminous efficiency and low power consumption, LED lights have become a key technology in the field of lighting. Compared with traditional lamps, LED lamps have the characteristics of color and brightness that are easier to meet individual dimming needs. However, when LED lights are used for home lighting, they can only control the power on and off under normal circumstances, and the features such as dimming and color adjustment have not been brought into play. When it is applied to the occasions where the lighting space is relatively large, due to the l...
