1. Energy saving
　　Research data show that because LED is a cold light source, semiconductor lighting itself does not pollute the environment. Compared with incandescent led lighting [1] lamps and fluorescent lamps, the power saving efficiency can reach more than 90%. Under the same brightness, the power consumption is only 1/10 of that of ordinary incandescent lamps and 1/2 of that of fluorescent tubes. If LEDs are used to replace 50% of our current traditional lighting, the electricity saved in my country each year is equivalent to the total power generation of a Three Gorges Power Station, and its energy-saving benefits are very considerable.

2. Healthy
　　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 The heat is low and it is safe to touch; these are beyond the reach of 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.
　　Because the current single LED has low power and low brightness, it is not suitable to be used alone, and the assembly of multiple LEDs together to design a practical LED lighting fixture has broad application prospects. The luminaire designer can determine the shape of the luminaire’s optical system, the number of LEDs and the size of the power according to the needs of the lighting object and luminous flux; it is also possible to combine several LED luminous tubes into a point light source, ring light source or surface light source. "Light source", design lamps according to the combined "secondary light source".

3. Artistic
　　 Light color is the basic element of visual aesthetics and an important means to beautify the room. The selection of the light source directly affects the artistic effect of the light. LED shows unparalleled advantages in the artisticization of light color display lamps; current color LED products have covered the entire visible spectrum, and have good monochromaticity, high color purity, red and green The combination of yellow and yellow LEDs makes the choice of color and gray scale (16.7 million colors) more flexible. Lamps are luminous sculptures. The material form of lamps constructed from materials, structure, form and texture is also an important means of displaying art. LED technology enables room lamps to better organically combine science and artistry, breaking the borders of traditional lamps, and surpassing the inherent concept of so-called lamp shape. Lamp design is based on the artistic creativity of visual perception and shape. To know, understand and express the theme of light from a new perspective. We can more flexibly use the combination of light and dark, the combination of light and color, the advantages of material and structural design in optical technology, and improve the design freedom to weaken the lighting function of the lamp, making the lamp a visual art, creating comfortable and beautiful Light art effect. For example, a candle-like LED lamp made of translucent synthetic materials and aluminum can be placed on the ground, corner or table at will. The concept is simple and relaxed, and the visual experience and light experience conveyed by the shape make the lamp full of fun and vitality. Life form.

Four, humanization
　　 Undoubtedly, the relationship between light and people is an eternal topic. "When people see the lamp, I see the light". It is this classic sentence that has changed the understanding of countless designers about the lamp. The highest state of lamps is the "shadowless lamp", which is also the highest embodiment of humanized lighting. There is no trace of common lamps in the room, so that people can feel the light but cannot find the light source, which reflects the humanized design that perfectly combines light and human life. .
