Embodiment 1

[0031] This embodiment discloses as figure 1 The seven-color channel control method of an LED lamp includes the following steps:

[0032] S1 powers on and initializes the main control module of the LED lamp;

[0033] S2 configures the RGB channel sequence and quantity of the LED lamp according to the LED lamp layout requirements;

[0034] S3 simulates the layout of LED lights through the order and quantity of RGB channels, and sets the type of lights;

[0035] The S4 main control module sets the address of each light point of the LED light through the write address command;

[0036] After the S5 main control module captures the data, it converts RGB according to the type of lamp;

[0037] S6 combines the control information of the signal control controller to reorganize and sort the data;

[0038] The S7 main control module packs the data of a single controller and sends it to the corresponding controller.

[0039] In S2, the main control module controls the channel throu...

Abstract

The invention relates to the technical field of LED lamp control, in particular to a seven-color channel control system and method for an LED lamp. The method comprises the steps of: performing initializing after a LED lamp main control module is powered on to work; configuring the RGB channel sequence and number of the lamp beads according to the layout requirement of the LED lamp; simulating thelayout of the LED lamps according to the sequence and number of the RGB channels, and setting the types of the lamps; enabling the main control module to set the address of each lamp point of the LEDlamp through the address writing command; after the main control module captures the data, converting the RGB according to the type of the lamp; combining the control information of the signal control controller to recombine and sort the data; and enabling the main control module to pack the single controller data and send the packed controller data to the corresponding controller. According tothe invention, through flexible arrangement, the selection of chips by actual projects is wider, and the mixed use of the chips can be supported. Part of control requirements at present can be met, and high expandability is achieved.

Description

technical field [0001] The invention relates to the technical field of LED lamp control, in particular to a seven-color channel control system and method for LED lamps. Background technique [0002] The seven-color channels of LED lights include: common RGBW color control + D (brightness) + strobe (S) + color temperature (C). According to the actual channel type of the lamp, the lamp type can be freely combined and changed in the software, such as RS, BGRC, etc. [0003] The software converts RGB to RGBW according to the channel type and the set mode (four-color mode, five-color mode, normal mode), and combines DSC to sort the data and send the data. [0004] At present, LED lights have evolved into multiple color modes and control modes through the previous RGB mode, but the previous software did not support this requirement simultaneously. Contents of the invention [0005] Aiming at the deficiencies in the prior art, the present invention discloses a seven-color chann...
