How do we choose the model parameters of the LED pattern light

Lighting technology LED pattern light parameters. The bedroom needs a light. In fact, it needs the light from the lamp. The reason why we must first understand the "light" of the LED pattern light. The better light source in nature is the sun. Human ancestors have known for hundreds of millions of years, and it should often be thought that the closer the car lights are to the sun, the better. There are three parameters to judge whether the light is suitable: illuminance, color saturation, and LED color temperature.

Illuminance refers to the luminous flux of visible light received per unit area. The unit is Lux. It is used to describe the brightness of the light, that is, the owner’s most concern about the LED pattern light "Is the lamp bright enough", the specific value can be measured with an illuminance meter. To be honest, a large thermal efficiency means a large saturation, but the luminous rate of different types of LED lights can vary greatly, for example, 8W LED lights and 40W incandescent lights are actually the same bright. Commonly used illuminances in family life are: entrance, storage room 50-150 Lux, living room 100-300 Lux, bedroom 50-200 Lux, working area 250-300 Lux, dining room, kitchen, bathroom 100-200 Lux.

Color rendering index

Refers to the reduction degree of light to the object color LED pattern light, the sunlight is 100, the external lighting should be above 63, and the indoor should be within 80. The light with high color rendering index is very true to the performance of contrasting colors; the light with low lumen value will cause color distortion and severely increase visual fatigue.

The illuminance, color temperature and lumen of the two LED pattern lights affect each other. Under the appropriate illuminance, determine the appropriate color temperature and luminous flux of the light to get a good sensory experience.

There are bedroom lights. When the lighting factor is 150 Lux, use warm white light with a contrast of 3000K. If the LED pattern light uses yellow or white light, the color will be too dark or distorted.
