At present, the dimming and color matching technology of LED lighting fixtures is mostly composed of multiple light-emitting diodes with different color temperatures or different colors. The dimming and color matching method of light-emitting diodes is designed according to the color temperature requirements of the light-emitting diode lighting fixtures when they are fully lit and the brightness and color temperature change curves of ordinary incandescent lamps, and the corresponding driving circuits are designed according to the dimming methods and methods to realize LED lighting The dimming and color matching of lamps give full play to the incomparable advantages of the new LED light source in terms of light efficiency, service life and environmental protection.

For comfortable lighting in specific places, LED lighting fixtures can simulate incandescent or halogen dimming and toning in various ways. The commonly used methods are as follows:

1. The RYGCB five-color light source is used for light mixing. It can be used for light color control, white light color temperature control and high color rendering index through a dedicated LED lighting fixture dimming color mixing circuit and control device. As long as the corresponding scene is set, the dimming effect of simulating incandescent or halogen lamps can be realized. At present, due to cost factors and the complexity of control circuits, led light sources are only used in some high-end lighting occasions.

2. RGBW four-color LED light source is used for light mixing, and can be used for color control and color temperature control of light through a dedicated LED lighting fixture dimming and color mixing circuit and control device. As long as the corresponding scene is set, the dimming effect of simulating incandescent or halogen lamps can be achieved. At present, due to cost factors and the complexity of control circuits, LED light sources are only used in some high-end lighting applications.

3. The led lighting uses multi-channel LED light sources with different color temperatures to mix the light. Through a dedicated LED lighting fixture dimming and color matching circuit, the LED light source can simulate the dimming and color matching mechanism of incandescent or halogen lamps after dimming. It is usually obtained by mixing a low color temperature LED light source (such as 2000K) and a high color temperature LED light source (such as 4000K), which is the most commonly used dimming and color matching method at present.
