LED lighting is a general term for LED lamps. With the further maturity of LED technology, LED will achieve more and better development in the field of design and development of room lighting. The design of room lighting in the 21st century will be based on LED lighting design as the mainstream, at the same time fully reflect the development trend of energy-saving, healthy, artistic and humanized lighting, and become the dominant lighting culture in the room.
energy saving
Research data shows that because 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 the ordinary incandescent lamp and 1/2 of the fluorescent tube. If we use LED to replace 50% of our current traditional lighting, the electricity saved in my country every year is equivalent to the sum of the power generation of a Three Gorges Power Station, and its energy saving benefits are very considerable.
healthy

LED is a green light source. The LED lamp is driven by DC, no stroboscopic; no infrared and ultraviolet components, no radiation pollution, high color rendering and strong luminous directionality; good dimming performance, no visual error when the color temperature changes; cold light source Low heat and safe to touch; these are out of reach of incandescent and fluorescent lamps. It can not only provide a comfortable lighting space, but also well meet the needs of people's physical health. It is a healthy light source that protects eyesight and is environmentally friendly.

Due to the low power and low brightness of a single LED at present, 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 lighting designer can determine the shape of the optical system, the number of LEDs and the power of the lighting according to the requirements of the lighting object and luminous flux; it is also possible to combine several LED light-emitting tubes into a point light source, a ring light source or a "secondary" surface light source. Light source", design lamps and lanterns according to the combined "secondary light source".
artistic

Light and color are the basic elements of visual aesthetics and an important means to beautify a room. The selection of light source directly affects the artistic effect of lighting. LED has shown unparalleled advantages in the art of light color display lamps. At present, color LED products have covered the entire visible spectrum range, and have good monochromaticity, high color purity, red and green. The combination of , yellow LED makes the choice of color and grayscale (16.7 million colors) more flexible. Lamps are luminous sculptures, and the material form of lamps constructed by materials, structures, shapes and textures is also an important means of displaying art. LED technology makes room lamps combine science and artistry better, breaking the borders of traditional lamps and lanterns, beyond the inherent concept of so-called lamps and lanterns, lamps and lanterns are designed in the artistic creative expression of visual perception and form, with a A whole new perspective to recognize, understand and express the subject of light. We can make more flexible use of the combination of light and dark, the combination of light and color, the advantages of material and structural design in optical technology, improve the degree of freedom of design to weaken the lighting function of lamps, make lamps and lanterns become a kind of visual art, create comfortable and beautiful light art effects. For example, LED lamps made of translucent synthetic materials and aluminum similar to candles can be placed on the ground, corners or tables at will. The concept is simple and relaxed. The visual experience and light experience conveyed by the form make the lamps full of fun and vitality. the living body.
      Humanize

There is no doubt that the relationship between light and people is an eternal topic. "People see the light, I see the light." It is this classic saying that has changed the understanding of countless designers about lights. 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 that people can feel the light but cannot find the light source, reflecting the humanized design that perfectly combines light and human life. .

design concept
There are two design concepts for LED lighting: one is that in 2008, Philips proposed to design lamps based on environmental needs, which is called scene lighting. The other is that in 2009, Casio designed lamps based on people's needs, which is called the development of mood lighting.

For LED lamps, LEDs of different light colors can be combined into various modules with soft illumination, which can be installed in the room at will. The light source of the room lighting may come from the ground, walls, windowsills, furniture, accessories, etc. Therefore, the future room lighting will no longer be limited to a single lamp, but will be transformed from a single lamp to a shadowless lamp with an overall lighting effect without the sense of a lighting appliance. Different light colors and brightness can have different effects on human physiology and psychology. In many cases, people do not need very bright white light. Maybe yellow light or other colors of light are more suitable for physiological and psychological needs. The three-primary LED can realize continuous transformation and selection of brightness, grayscale and color, so that the illumination can be expanded from white light in the general sense to light of various colors.

market
Therefore, people can set the lighting effect according to the overall lighting needs (such as color, temperature, brightness and direction, etc.), realize humanized intelligent control, and create different indoor lighting effects. Even if there are only LED luminous ceilings and luminous walls in the room, people can choose and control the brightness, grayscale, and color changes of light in different spaces and times according to their own requirements, scene conditions, and different understandings of the environment and life. , simulate various light environments to guide and improve mood, and reflect a more humanized lighting environment.
