Embodiment Construction

[0057] In various embodiments of the present invention, the control method for any LED lamp in the multi-LED lamp is the same, so the following mainly takes the control method of one LED lamp as an example to illustrate the multi-LED lamp control method and system of the present invention . The multi-LED lights refer to those LED lights that are installed close to each other and may affect each other when the ambient light intensity is detected. Among them, the control of LED lights is mainly to control the light-emitting conditions of the light-emitting parts of LED lights (such as: LED light boards, LED lamp beads), these light-emitting conditions include: controlling whether the light-emitting parts are on or not, controlling the degree of brightness of the light-emitting parts, etc. .

[0058] Please refer to figure 1 , is a schematic flowchart of the first embodiment of the method for controlling multiple LED lamps provided by the present invention. figure 1 The method...

Abstract

The invention provides a control method and system of multiple LED (Light Emitting Diode) lamps. The method comprises the following steps of: before outputting pulse-driven current to the LED lamps, detecting whether zero-crossing voltage occurs on the mains supply; when the zero-crossing voltage is detected, outputting the pulse-driven current to the LED lamps, or waiting till the zero-crossing voltage is detected; and in the time interval of two adjacent pulses of the pulse-driven current, detecting the intensity of ambient light, and according to the detected intensity of the ambient light, controlling the light emitting condition of the LED lamps. The system comprises a control subsystem, wherein the control subsystem comprises a power module, a processor, a zero-crossing detection module and an ambient-light detection module. The invention has the advantages that when the intensity of the ambient light is detected, not only is the influence by the self light emitted from the LED lamps not caused, but also the influence by the light emitted from the adjacent LED lamps is not caused.

Description

technical field [0001] The invention relates to the field of intelligent lighting, in particular to a multi-LED lamp control method and system. Background technique [0002] In intelligent lighting, the control of LED (Light Emitting Diode, light-emitting diode) lights is sometimes based on ambient light, that is, when the ambient light is detected to indicate daytime, the LED light is turned off, and when the ambient light is detected to indicate When it is night, turn on the LED light. In the prior art, in the process of detecting the intensity of ambient light, there are two main difficulties: one is how to avoid the influence of the LED lamp itself on the light emission, and the other is how to avoid the influence of the light emission of the adjacent LED lamps. Contents of the invention [0003] In view of this, the present invention provides a multi-LED lamp control method and system. When the method and system detect the intensity of ambient light, they can not on...
