In the past, only stage lighting and some light shows would use lighting control, but now with the popularization of intelligent lighting, smart lighting control has become an important part of lighting design. Lighting control is usually composed of sensors, scene control, switch control modules, etc., to achieve linkage of lights with changes in the scene. Through lighting control, different lighting, color temperature, brightness, light spots, etc. can form an aesthetic and artistic lighting atmosphere.
The energy-saving effect achieved by different smart lighting control systems will be quite different. Use appropriate costs to achieve the optimal configuration. The optimized lighting control system can reduce circuit failures, prolong the life of the light source. And simplify design, wiring, and maintenance operations.
Method of LED brightness control:
The brightness of the LED changes with the magnitude of the current, which is proportional to the relationship. The brightness of the LED can be adjusted by controlling the output current of the LED power supply within the allowable range of the LED. The PMW dimming method is usually used now, and the brightness is adjusted by changing the pulse width. How to adjust the color temperature of LED lamps:
- Synthesize the color temperature of white light through red, green and blue light
- Adjust the color temperature through the control of the chip and current. This adjustment method can often achieve stepless dimming and color temperature adjustment.
- Adjust the color temperature through the combination of white light and yellow light
- Adjust the color temperature by mixing the cold and warm color temperature. This method is often used for three-stage dimming and toning. It should be noted that the intermediate color temperature is the maximum power of the lamp at this time, which means that if the anti-blue light level is measured, the anti-blue light level of the intermediate color temperature needs to be measured, not the anti-blue light level when the color temperature is measured.
A smart lighting control system usually includes a controller, power supply, light source, sensor, gateway, etc.
Now LED smart lighting control system has entered ordinary households. And refrigerators, TVs, air conditioners, water dispensers, etc. have become part of the smart home system. Smart home lighting systems usually include lighting controllers, gateways, integrated controls such as apps, switch panels, sensors, etc. Many manufacturers are now vigorously developing smart lighting.
The most basic function of smart lighting is dimming and color adjustment. In other words, the color temperature and brightness can be adjusted steplessly to adapt to different application scenarios. For example, the light automatically turns on when I open the door, and automatically turns off when I leave. The more practical intelligent functions applied to lighting also include the timing switch function and the delayed turn-off function. Another application scenario is that when the lamp is turned on at night, the light suddenly turns on and it will make people feel dazzling. If the light changes from dim to gradually brighter, the human eyes will be more comfortable. There is also an algorithm for intelligent lighting, called the daylight algorithm. This algorithm has been applied to processes such as ceiling lamps or desk lamps. The effect achieved is to simulate the change of natural light, usually with a light sensor, making people’s work and rest more regular.
