At the same brightness, the power consumption is only110 of ordinary incandescent lamps and12 of fluorescent lamps.
If LED is used to replace 50% of our traditional lighting, the electricity saved in China is equivalent to the sum of the annual power generation of a Three Gorges power station, and its energy-saving benefits are considerable.
Second, health: LED is a green light source.
LED lamp is driven by DC, without stroboscopic; Does not contain infrared and ultraviolet components, has no radiation pollution, high color rendering and strong luminous direction; Good dimming performance, no visual error when the color temperature changes; The cold light source has low calorific value and can be safely touched; These are beyond the reach of incandescent lamps and fluorescent lamps.
It can not only provide comfortable lighting space, but also meet people's physiological health needs. It is a healthy light source for protecting eyesight and protecting the environment.
Starting from 20 14, a single LED is not suitable for single use because of its low power and low brightness. However, designing multiple LEDs into practical LED lighting lamps has broad application prospects.
Designers of lamps can decide the shape of optical system, the number and power of light-emitting diodes according to the requirements of lighting objects and luminous flux. It is also possible to combine several LED tubes into a "secondary light source" of point light source, ring light source or surface light source, and design lamps according to the "secondary light source" of the group.
Third, artistry: light and color are the basic elements of visual aesthetics and an important means to beautify the room.
The choice of light source directly affects the artistic effect of lighting, and LED shows incomparable advantages in the artistry of light and color display lamps. Color LED products have covered the whole visible spectrum range, with good monochromaticity and high color purity. The combination of red, green and Huang San LEDs makes the choice of color and gray scale (16.7 million colors) more flexible.
Lamps and lanterns are luminous sculptures, and the material form of lamps and lanterns composed of materials, structures, shapes and textures is also an important means to express art.
LED technology makes indoor lamps better combine science and artistry, breaks the traditional framework of lamps and goes beyond the inherent concept of so-called lamp form. Lighting design recognizes, understands and expresses the theme of light from a brand-new angle in visual perception and artistic expression of form.
We can use the advantages of light and shade, light and color combination, material and structure design in optical technology more flexibly, improve the design freedom to weaken the lighting function of lamps, make lamps a visual art, and create comfortable and beautiful lighting artistic effects.
For example, translucent materials like candles and LED lights made of aluminum can be placed on the ground, corner or table at will. The concept is simple and relaxed, and the visual feeling and light experience conveyed by the form make lamps a life full of interest and vitality.
4. Humanization: Undoubtedly, the relationship between light and people is an eternal topic. "People see light, I see light." It is this classic sentence that has changed the understanding of light by countless designers.
The highest state of lamps and lanterns is "shadowless lamp", which is also the highest embodiment of humanized lighting. There are no traces of common lamps in the room, so people can feel the light but can't find the light source, which embodies the humanized design of the perfect combination of light and human life.
