Embodiment Construction

[0043] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] The invention provides a method for sending and receiving LED dimming codes.

[0045] refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of the method for sending and receiving LED dimming codes according to the present invention. A method for transmitting and receiving LED dimming codes provided in this embodiment, the method for transmitting and receiving includes the following steps:

[0046] Step S10, when receiving the user instruction, the sending end continuously transmits the original code corresponding to the user instruction at least twice.

[0047] In this embodiment, the user instruction includes: dimming requests such as LED brightness adjustment, LED color adjustment, and LED saturation adjustment. When the sending end receives the above user instruction, it obtains the ...

Abstract

The invention discloses an LED dimming code transmitting and receiving method. The transmitting and receiving method comprises the following steps: when a user instruction is received by a transmitting end, the transmitting end is used to continuously transmit original codes corresponding to the user instruction at least twice; a receiving end is powered up periodically to acquire a code sequence, wherein the code number of the code sequence is greater than or equal to the code number of the original codes; according to the mapping relationship between the preset code sequence and the original code, a processing end is used to restore the acquired code sequence to obtain the corresponding original codes, and perform dimming response according to the restored and obtained original codes; and the time for the transmitting end to continuously transmit the original codes is greater than the power-up period of the receiving end. The invention further discloses an LED dimming code transmitting and receiving system. According to the invention, the disadvantage of large power consumption caused by the reason that the signal receiving end is always in the power-up working state in the prior art can be overcome so as to achieve the purpose of energy saving.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to a method and system for sending and receiving LED dimming codes. Background technique [0002] LED (Light Emitting Diode, light emitting diode) can emit light of various colors. With the development of technology, the brightness, chroma, and color saturation of LEDs can be adjusted in real time according to people's needs. Dimmable LED light source has become a trend. LED dimming signals are usually transmitted wirelessly, and infrared signal transmission is the most widely used. At present, the infrared encoding formats commonly used in the market include NEC's 6122 format, Philips RC5 format, Sony SIRC format, Nokia NRC17 format, Sharp format, etc. These encoding formats all have a common feature: encoded burst transmission, that is, the dimming signal is only transmitted one launch. Based on the sudden emission of the dimming signal, the infrared receiver needs to be in the power-on wo...
