LED lighting design development trend
The transformation of LED lighting will expand people's lighting concept. LED will reflect the development trend of energy saving, health, art and humanity in the design of 21st century living room lighting.
The lighting of the living room is inseparable from the lighting, and the lighting is a concentrated reflection of the lighting. It is not only a tool for completing the function of the living room building, creating visual conditions, but also a part of the decoration of the living room, and a unity of lighting technology and architectural art. Modern lighting not only plays a role in lighting in the living room, but also is a major part of creating a living environment. The use of luminaire styling and the coordination of light color can make the living room environment have a certain atmosphere and artistic conception, embody a certain style and personality, increase the beauty of architectural art, and make the indoor space more in line with people's psychological and physiological needs and aesthetic taste. As a new type of lighting technology, LED has attracted worldwide attention. Especially high-brightness LEDs have been hailed as the most valuable light source in the 21st century, which will definitely lead to a new revolution in the field of lighting. Since the appearance of white LEDs, both the principle of illumination and the functions have advantages that other traditional light sources cannot match. Therefore, LED lighting has become a trend in the field of residential lighting in the 21st century. LEDs are combined with traditional incandescent lamps and fluorescent lamps. Lighting has opened up a new world. The content and form of luminaire design is mainly light. The new Led Light source has promoted the innovation of lighting design and development, which has changed our lighting concept to a large extent, so that we can liberate from the limitations of traditional point and line source, luminaire design. The language and concept can be freely played and re-established. The lamps have more flexibility in the visual expression of perception and form, and the room lighting fixtures will be more energy-saving, healthy, artistic and humanized.
First, energy saving
Research data shows that because LED is a cold light source, semiconductor lighting itself has no pollution to the environment, compared with incandescent lamps and fluorescent lamps, the power saving efficiency can reach more than 70%. At the same brightness, the power consumption is only 1/10 of that of an ordinary incandescent lamp and 1/2 of a fluorescent tube. If we replace 50% of our current traditional lighting with LEDs, the amount of electricity saved in China is equivalent to the sum of the power generation of a Three Gorges Power Station, and its energy-saving benefits are considerable.
Second, health
The LED is a green light source. LED lamp DC drive, no stroboscopic; no infrared and ultraviolet components, no radiation pollution, high color rendering and strong directionality; good dimming performance, no visual error when color temperature changes; cold light source Low heat and safe touch; these are not possible with incandescent and fluorescent lamps. It not only provides comfortable lighting space, but also satisfies people's physiological health needs. It is a healthy light source that protects vision and is environmentally friendly.
Since the current single LED has low power and low brightness, the individual use sometimes fails to meet the illumination brightness requirement, and the assembly of multiple LEDs into a practical LED lighting fixture has broad application prospects. The luminaire designer can determine the shape of the optical system of the luminaire, the number of LEDs and the power according to the requirements of the illumination object and the luminous flux. It is also possible to design several LED illuminating tubes into a "secondary" of point light source, ring light source or surface light source. The light source" is designed according to the combined "secondary light source".
Third, artistic
Light color is the basic element that constitutes visual aesthetics, and is an important means of beautifying the living room. The choice of light source directly affects the artistic effect of lighting. LED has shown unparalleled advantages in the artistic display of light color display lamps; currently color LED products have covered the entire visible spectrum range, and have good monochromaticity, high color purity, red and green. The combination of yellow LEDs gives greater flexibility in the choice of color and grayscale (16.7 million colors). The luminaire is a luminous sculpture. The material form of the luminaire constructed from materials, structures, shapes and textures is also an important means of displaying art. LED technology makes the living room lamps more scientifically and artistically combined, breaking the side frame of traditional lamps, surpassing the inherent concept of so-called lamp form, the design of lamps in the visual and visual artistic expression, with a A new perspective to understand, understand and express the theme of light. We can more flexibly use the combination of light and dark in optical technology, the combination of light and color, the advantages of material and structural design, and improve the freedom of design to weaken the lighting function of lamps, making lamps become a visual art, creating comfort and grace. The light art effect. For example, translucent synthetic materials and candle-like LED lamps made of aluminum can be placed on the ground, on the corners or on the table. The concept is simple and relaxed. The visual experience and the experience of light make the lamps full of fun and vitality. The body of life.
Fourth, humanization
Undoubtedly, the relationship between light and people is an eternal topic. "People see the lights, I saw the light." It is this classic discourse that has changed the understanding of the lamps by countless designers. The highest level of lighting is the "shadowless lamp" 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 can not find the light source, reflecting the humanized design that perfectly combines light and human life. .
LED lamps are small and light, and can be combined with LEDs of different light colors to form various modules with soft illumination. They can be installed in the living room. The light source of the room lighting fixtures may be from the ground, wall, window sill, furniture, accessories and so on. As a result, future room lighting will no longer be limited to a single luminaire, but will be converted from a single luminaire to a shadowless lamp with no overall illumination of the luminaire. Different light colors and brightness have different effects on human physiological and psychological energy. 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 color LEDs enable continuous transformation and selection of brightness, grayscale, and color, so that illumination expands from white light in a 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), realize the intelligent control of humanity, and create different indoor lighting effects. Even if there are only LED-illuminated ceilings and illuminated walls in the living room, people can choose and control the brightness, grayscale, and color changes of light in different spaces and times according to their requirements, scenes, and different understandings of the environment and life. It simulates various light environments to guide and improve emotions, reflecting a more humanized lighting environment.
Conclusion
With the further maturity of LED technology, LED will achieve more and better development in the field of room lighting design and development. The lighting design of the 21st century room will be based on the design of LED lamps, and at the same time fully reflect the development trend of energy-saving, healthy, artistic and humanized lighting, and become the leading of the room lighting culture. In the new century, LED lighting fixtures will surely illuminate everyone's living room, change everyone's life, and become a great revolution in lighting development and design.
