Embodiment Construction

[0053] Explanation: In this patent application document, if there are expressions similar to "first resistance" and "second resistance", it does not necessarily mean that "first resistance" must appear before "second resistance" in this article. Just to show that these are two different gauge resistors. Sometimes, in order to match the description of the circuit diagram, "the second resistor" may appear before the "first resistor" in the claims or specification.

[0054] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0055] refer to figure 1 , the present invention discloses a control device with multiple LED power ...

Abstract

The invention discloses a control device for parallel connection of multiple LED power supplies for light control and dimming, including: a master-slave power supply determination module, a master power supply module and a slave power supply module; the master-slave power supply determination module is used for detecting results according to environmental conditions Set the main power module and the slave power module; the main power module converts the collected environmental state detection information into a synchronous signal, sends it to the synchronous signal receiving circuit through the synchronous signal sending circuit, reads the synchronous signal from the power module, and according to the synchronous The signal reading result determines whether the output is turned on and the dimming is enabled or the output is turned off and the dimming function is turned off. The invention also discloses a control method corresponding to the device. The device and method enhance the control precision, improve the overall control performance and reduce the cost.

Description

technical field [0001] The invention relates to the lighting field of LED lighting devices, in particular to a control device and a control method for parallel connection of multiple LED power supplies with light control and light adjustment functions. Background technique [0002] Patent 2017206477155 discloses an intelligent lighting control system, which directly converts light information into corresponding light digital values, and transmits the light intensity value to the main control module through I2C communication, and the main control module determines the PWM that should be output according to the illuminance value. (Pulse Width Modulation, Pulse Width Modulation) signal, and the LED drive output rated current under the control of the PWM signal, so that the LED lighting device has a corresponding brightness. This process is in an infinite loop. According to the light value obtained in real time, the brightness of the LED lighting fixture is adjusted in real time...
