[0002] RGB LED screens and RGB lamps have different characteristics and require different effects, so they generally use different control signals and control protocols. In the prior art, when there are RGB LED screens and RGB lamps in the same space, they can only be controlled separately, which makes it difficult to achieve unified and coordinated changes, and the overall application effect of the space looks messy; in addition, the separate control method increases the cost of system learning for engineers and increases the difficulty of debugging.

DETAILED DESCRIPTION

[0015] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0016] The present invention is a system for realizing synchronous control of RGB lamps and RGB LED screens, comprising a computer 1 installed with control software, an LED master control 2, an LED control card 3, a signal conversion control module 4, an RGB LED screen 5, a PWM signal amplifier 6 and an RGB lamp 7.

[0017] The computer 1 is connected to the signal input end of the LED main control 2, and the signal output end of the LED main control 2 is connected to the LED control card 3. The control signal output by the LED control card 3 is divided into two parts and respectively connected to the input end DIN of the signal conversion control module 4 and the RGB LED screen 5. The signal conversion control module 4 converts the control signal into a PWM signal and outputs it to the PWM signal amplifier 6 accordingly. The output end of the PWM signal amplifier 6 is connected to the color corresponding to the RGB lamp 7.

[0018] refer to Figure 1 and Figure 2 Shown is a specific embodiment of the present invention.

[0019] When there are multiple signal conversion control modules 4 , the output terminal DOUT of the previous signal conversion control module 4 is connected to the input terminal DIN of the next signal conversion control module 4 ′.

[0020] The above-mentioned signal conversion control module 4 is mainly a device that can convert conventional screen control signals into signals that can be directly used by LED lamps, including a power module 41, a signal input module 42, a data forwarding module 43, a signal output module 44, a data translation module 45 and a PWM output module 46.

[0021] The power supply module 41 is used for internal power supply of the signal conversion control module 4; the signal input module 42 is used for receiving the control signal output by the LED control card 3 for controlling the RGB LED screen 5; the data forwarding module 43 is used for forwarding the control signal received by the signal input module 42 except the signal used by itself to the signal output module 44; the signal output module 44 sends the control signal to the next signal conversion control module 4 (since the RGB lamp 7 is a single lamp itself, it requires fewer signals, and more RGB lamps 7 are required to achieve the entire control effect, so the signal needs to be forwarded, which is convenient for on-site operation); the data translation module 45 translates the control signal for controlling the RGB LED screen 5 into a PWM signal for use by the RGB lamp 7; the PWM output module 46 outputs the PWM signal to the PWM signal amplifier 6.

[0022] The data translation module 45 converts the received RGB color display value signal (0-255, 0-255, 0-255) for controlling the RGB LED screen 5 into a proportional value through re-encoding and then converts it into a duty cycle form of an analog quantity to form a PWM signal.

[0023] The control signal output by the signal conversion control module 4 is used to expand the LED power through the PWM signal amplifier 6. The PWM signal amplifier 6 is suitable for power amplification of PWM-controlled LED controllers and dimmers. There are constant voltage type and constant current type, which can be mixed and connected to facilitate unified control of LED lamps with different voltages, high power and low power. The RGB lamp 7 corresponding to the constant voltage PWM signal amplifier 6 must be a constant voltage type, and the RGB lamp 7 corresponding to the constant current PWM signal amplifier 6 must be a constant current type.

[0024] Through the above scheme, the two signals of the LED control card 3 of the present invention are the same. The LED main control 2, the LED control card 3, the RGB LED screen 5, and the RGB lamp 7 are powered on. When the control software of the computer 1 is turned on, the RGB LED screen 5 and the RGB lamp 7 can be debugged at the same time to achieve synchronous control of the two. This can allow the products used in the entire use space to produce a unified change effect, look more coordinated, make people feel more comfortable, and create more scene effects. In addition, the present invention can reduce the cost of system learning for engineers and reduce the difficulty of debugging.

[0025] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
