Led outdoor lighting has four dimming methods：
Linear dimming: The dimming feet of the constant current chip are used to adjust the current of led outdoor lighting to achieve the purpose of dimming. This technology works well, but the wiring is complicated and is not conducive to led outdoor lighting.
PWM dimmin: This method is similar to linear dimming. Like linear dimming, it is used by most led outdoor lightings.
Remote control dimming: There are remote control and wireless remote control, which can change the color temperature of led outdoor lighting, but it is more complicated to operate. This dimming method can be used for various led outdoor lightings, and also for some indoor lamps.
Segmented dimming: This type of dimming uses internal switches to achieve dimming. The advantage of this method is that no additional led outdoor lighting components are required. According to the original installation method, each led outdoor lighting can be dimmed Light. In addition, because the dimming mode is controlled by the power chip, high efficiency and high power factors can be achieved under full voltage conditions. The disadvantage is that it can only be adjusted according to the preset brightness, and stepless dimming cannot be achieved. In addition, there are few types of such ICs, and the current adjustment is not satisfactory.
As the technology matures, such dimming Technology will become the mainstream of led outdoor lighting technology in the future.
