Luminescence principle: LED lamps are small in size and light in weight, and can be combined with different LED colors to form various modules with soft illumination. They can be installed in the bedroom at will. The light source of indoor lighting fixtures may come from the ground, walls, windowsills, furniture, decorations, etc. Therefore, in the future, indoor lighting will no longer be limited to individual lamps, but will be transformed from single lamp lighting to shadowless lamps with no overall lighting effect without the sense of lighting fixtures. Different colors and brightness of light can have different effects on human physiology and psychology. In many cases, people do not need very bright white light, and yellow or other colors of light may be more suitable for physiological and psychological needs. Three primary color LEDs can achieve continuous transformation and selection of brightness, grayscale, and color, expanding lighting from white light in the general sense to light of multiple colors.
