Description

Technical Field

[0001] The utility model relates to the technical field of dimmers, in particular to an LED dimmer. Background Art

[0002] Many LED lights are currently used in everyday lighting to achieve energy savings. However, the light intensity of LED lights needs to be adjusted according to user habits, which requires an LED dimmer. An LED dimmer is an electrical device that changes the luminous flux of a light source in a lighting fixture, adjusting the illumination level. The purpose of a dimmer is to adjust the brightness of the light. By reducing or increasing the RMS voltage, the average power of the light produces different light output intensities. This allows users to adjust the brightness of the light as needed to suit different environments and scenarios. Most push-button LEDs on the market adjust brightness with a simple press, but only offer two brightness settings, making it impossible to achieve precise control of light brightness. Touch-controlled LED dimmers, on the other hand, allow for quick brightness adjustments using a touch panel, but their internal structure is complex, resulting in high production and maintenance costs. In actual use, it is easy to accidentally touch the touch panel, leading to misoperation. Therefore, a LED dimmer is needed to address these issues. Utility Model Content
