As a new type of lighting technology, LED has caused a new revolution in the field of lighting. The new LED light source promotes the innovation of lighting design and development, which has changed our lighting concept to a large extent, freeing us from the limitations of traditional point and line light sources, and the language and concept of lighting design can be freely displayed and re-established , The lamps and lanterns have greater flexibility in the creative expression of visual perception and form, and the lamps and lanterns will be more energy-saving, healthy, artistic and humane.

1. Energy saving of lamps

Since LED is a cold light source, semiconductor lighting itself does not pollute the environment. Compared with incandescent 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 lamps

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 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 lighting space, but also meet people's physiological health needs. It is a healthy light source that protects eyesight and is environmentally friendly.

Multiple LEDs assembled together to design a practical LED lighting fixture have 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".

Three, the art of lamps and lanterns

Light color is the basic element of visual aesthetics. The selection of the light source directly affects the artistic effect of the light. LED shows unparalleled advantages in the artisticization of light and color display lamps; currently, color LED products have covered the entire visible spectrum with good monochromaticity and high color purity. 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 lamps to better organically combine science and artistry, breaking the borders of traditional lamps, and surpassing the inherent concept of so-called lamp shape. The design of lamps and lanterns is based on the artistic creative expression of visual perception and shape. To recognize, understand and express the subject of light from a different perspective. Improve the design freedom to weaken the lighting function of the lamp, make the lamp a visual art, and create a comfortable and beautiful lighting art effect.

Fourth, humanized lamps

LED lamps are small in size and light in weight, and LEDs of different light colors can be combined into various modules with soft illuminance. Therefore, in the future, lighting will be transformed from a single lamp to a shadowless lamp with an overall lighting effect without a sense of lighting. Different light colors and brightness can have different effects on people's physiology and psychology. In many cases, people do not need very bright white light. Perhaps yellow light or other colors of light are more suitable for physical and psychological needs. Three primary color LEDs can achieve continuous conversion and selection of brightness, grayscale, and color, making the lighting expand from white light in the general sense to light of multiple colors.

Therefore, people can set the lighting effects according to the overall lighting needs (such as color, temperature, brightness, and direction, etc.), realize humanized intelligent control, and create different lighting effects. You can also select and control the brightness, grayscale, and color changes in different spaces and times according to their requirements, scene conditions, and different understandings of the environment and life, and simulate various light environments to guide and improve emotions. Reflect a more humane lighting environment.

Conclusion:

With the further maturity of LED technology, LED will achieve more and better development in the field of lighting design and development in the future. LED lighting design is currently the mainstream, and it fully reflects the development trend of energy-saving, healthy, artistic and humane lighting, and has become the dominant lighting culture.
