LED is a green light source. LED lights are driven by DC, no stroboscopic; no infrared and ultraviolet components, no radiation pollution, high color rendering and strong light-emitting direction; good dimming performance, no visual error when the color temperature changes; cold light source Low heat and safe to touch; these are not reachable by incandescent and fluorescent lamps. It can not only provide a comfortable light space, but also meet people’s physiological health needs. It is a healthy light source that protects eyesight and is environmentally friendly.
Since a single LED has low power and low brightness, it is not suitable to be used alone. However, assembling multiple LEDs together to design a practical LED lighting fixture has broad application prospects. The luminaire designer can determine the shape of the luminaire optical system, the number of LEDs and the size of the power according to the needs of the lighting object and luminous flux; also can combine several LED light-emitting tubes to design a point light source, a ring light source or a surface light source. “Light source”, design lamps according to the combined “secondary light source”.
