Abstract

The present invention provides an LED lighting system and a lighting control method thereof. The system includes one or more LED lamps; wherein, each LED lamp includes: a plurality of color temperature light sources with different color temperatures; a lamp control and power supply unit connected to the various A color temperature light source, including: a first interface for receiving an externally input PWM signal of the LED lamp, and a second interface for connecting to a power supply located outside the LED lamp, wherein the lamp control and power supply The unit matches the signal parameters of the received PWM signal with the preset signal parameters, and uses the color temperature light source associated with the matched preset signal parameters to realize color temperature adjustment, and obtains the color temperature light source associated with the matched preset signal parameters. The power drive mode is used to realize the brightness adjustment of the color temperature light source used.

Description

technical field [0001] This patent application relates to the technical field of LED lighting, in particular to an LED lighting system and a lighting control method thereof. Background technique [0002] LED (Light Emitting Diode) has become the most competitive new light source due to its high efficiency, pure light color, low energy consumption, long life, and no pollution. With the continuous improvement of LED luminous flux and luminous efficiency, the application of LED in the field of lighting is becoming more and more extensive. [0003] In the prior art, there are many ways to control the LED color temperature. For example, according to the internal feedback of the lamp or the external signal, the power supply of the lamp can be controlled to generate a corresponding control signal, and the ratio of light sources of different colors or color temperatures can be controlled to control the output of the light. color temperature. In the types of lamps with color temper...
