Four directions of LED lighting design and development
As a new type of lighting technology, LED's application prospects have attracted worldwide attention, especially high-brightness LEDs are hailed as the most valuable light source in the 21st century, which will surely cause a new revolution in the field of lighting.
Since the emergence of white light LEDs, both light-emitting principles and functions have advantages that other traditional light sources cannot match. Therefore, LED lighting has become a trend in the field of room lighting in the 21st century. LEDs will replace traditional incandescent lamps and fluorescent lamps. Lighting fixtures have faced severe challenges.
The content and form of lamp design is mainly light. The new LED light source promotes the innovation of lighting lamp design and development, which has changed our lighting concept to a large extent, so that we can be liberated from the limitations of traditional point and line light sources. Lamp design The language and concept of the lamp can be freely used and re-established. The lamps and lanterns have greater flexibility in the creative expression of visual perception and form. The room lighting lamps will be more energy-saving, healthy, artistic and humane.
1. 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 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. Health
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.
At present, a single LED has low power and low brightness, so 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’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. .
LED lamps are small in size and light in weight. You can choose different light colors to combine LEDs into various modules with soft illuminance, which can be installed arbitrarily in the room. The light source of the room lighting may come from the ground, wall, window sill, furniture, ornaments, etc.
Therefore, in the future, room lighting will no longer be limited to a single lamp, but will transform from a single lamp lighting into a shadowless lamp with an overall lighting effect without the sense of lighting equipment. Different light colors and brightness 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, so that the lighting expands from white light in the general sense to light of multiple colors.
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 light-emitting ceilings and light-emitting walls in the room, people can choose 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. , Simulating various light environments to guide and improve emotions, reflecting a more humane lighting environment.
