Embodiment 1

[0031] This embodiment discloses as figure 1 A seven-color channel control method for an LED light is shown, including the following steps:

[0032] S1 powers on the LED light main control module and initializes it;

[0033] S2 configures the order and number of RGB channels of the lamp beads according to the LED lamp layout requirements;

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

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

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

[0037] S6 combines the conversion signal to control the control information of the controller, and reorganizes and sorts the data;

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

[0039] In S2,...

Embodiment 2

[0045] This embodiment discloses a seven-color channel control system for an LED lamp, including a main control module, the main control module includes a main control chip, a reset circuit, a clock circuit and a download circuit, the main control chip includes a central processing unit, a programmable Flash, programmable EEPROM, data memory SRAM, timer / counter, general purpose I / O port, programmable serial USART, SPI serial port, two-wire serial interface TWI, and data, address and control buses.

Abstract

The present invention relates to the technical field of LED lamp control, in particular to a seven-color channel control system and method for LED lamps. The present invention initializes the main control module of the LED lamp after it is powered on and works; configures the RGB channel sequence of the lamp beads according to the layout requirements of the LED lamp and quantity; simulate the layout of LED lamps through the RGB channel sequence and quantity, and set the lamp type; the main control module sets the address of each light point of the LED lamp through the write address command; conversion; combined with the control information of the signal control controller, the data is reorganized and sorted; the main control module packs the data of a single controller and sends it to the corresponding controller; the invention enables the actual project to select the chip through flexible settings More widely, it can support the mixed use of chips. It can solve some of the current control needs and has strong scalability.

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 an LED lamp. Background technique [0002] The seven color channels of the LED light include: ordinary RGBW color control + D (brightness) + strobe (S) + color temperature (C). According to the actual channel type of the luminaire, the luminaire 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), sorts the data and sends the data after combining with DSC. [0004] At present, LED lights have evolved into a variety of color modes and control modes through the previous RGB mode, but the previous software did not support this requirement synchronously. SUMMARY OF THE INVENTION [0005] In view of the deficiencies of the prior art, the present invention di...
