Different lights have different effects on the human body. For example, when you are at work, bright lights can make you more energetic; and when you want to watch a movie at home on a leisurely weekend night, of course, dim lights can make you more involved in the plot; High-end hotels and restaurants, different spaces at different times, have different lighting atmospheres, which will make guests feel more comfortable and comfortable. Today, with the emergence of individual needs and technological innovations, lamps with dimming functions have become quite common, so as to create different lighting effects for users. And the "hero" behind this is, of course, the LED dimming power supply.

The dimming power supply changes the illuminance and color temperature of the light source by adding a dimming control module inside the power supply and controlling the power supply through an external signal source. The key difference between it and the ordinary power supply is that it is controllable. The ordinary power supply only has the function of on and off, while the dimming power supply can add a variety of working states according to its dimming method, and can be adjusted according to the comfort of the human eye, the environment or the scene. Brightness, color, etc. of lights.

At present, the common dimming methods of LED dimming power supply on the market include 0-10V dimming, thyristor dimming, DALI dimming, DMX dimming, etc. 0-10V and thyristor dimming are especially widely used, and the development is relatively mature. 0-10V dimming has a wide range of applications, low cost and strong compatibility; thyristor dimming can transform lighting without dimming function into lighting with dimming function without changing the traditional wiring.

Common applications of dimming power supply

1. Indoors, general exhibition halls, hotels, clubs and other scene lighting places, as well as home lighting, are used to illuminate different scene atmospheres. For example, adjust different color temperatures according to different seasons, such as adjusting the warm color temperature in winter, giving people a warm and soft feeling, and adjusting the cold color temperature in summer, giving people a refreshing feeling.

2. Outdoor, street lamps, landscape lighting, etc. Street light dimming power supply is mainly to achieve energy-saving effect, realize on-demand lighting under the condition of meeting functional requirements, and realize energy saving to the greatest extent. At the same time, the illumination of the light source is adjusted according to different time periods to meet the requirements of different time periods and reduce light pollution.

3. Landscape lighting, dimming power supply has both energy saving and situational needs. For example, the landscape lighting needs of holidays and weekdays are definitely different. At this time, the dimming power supply needs to be adjusted and controlled.
