Analysis on design and development trend of LED lamps in 2011

As a new type of lighting technology, LED's application prospect has attracted worldwide attention. Especially high-brightness led is praised as a valuable light source in, which will surely lead to a new revolution in the lighting field. Since the emergence of white led, it has the advantages that other traditional light sources cannot match in terms of both luminous principle and function. Therefore, led lighting has become a trend in the field of room lighting in the 21st century, led will replace traditional incandescent lamps and fluorescent lamps, and traditional lighting lamps in living rooms have already faced severe challenges. The content and form of lamp design are mainly light. The new led light source promotes the innovation of lighting design and development, which has greatly changed our lighting concept, so that we can be liberated from the limitations of traditional point and line light sources, and the language and concept of lamp design can be freely developed and re-established, lamps and lanterns have more flexible space in visual perception and creative expression of form, and bedroom lighting lamps and lanterns will develop towards more energy-saving, healthy, artistic and humanized development. 1. Energy-saving research data show 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 energy-saving efficiency can reach more than 90. At the same brightness, the power consumption is only 1/10 of that of ordinary incandescent lamps and 1/2 of that of fluorescent lamps. If led is used to replace 50 of our current traditional lighting, the electricity saved in our 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. Second, the healthy 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 luminous directivity; Good dimming performance, no visual error when color temperature changes; The Cold Light source has low calorific value and can be safely touched; These are not available for incandescent and fluorescent lamps. It can not only provide comfortable lighting space, but also well 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 small power and low brightness, so it is not suitable to be used alone. However, it has broad application prospects to assemble multiple LEDs together to design practical led lighting lamps. The lamp designer can decide the shape of the lamp optical system, the number of LEDs and the size of power according to the requirements of lighting objects and luminous flux; Several led light-emitting tubes can also be combined and designed as 'secondary light source' of point light source, ring light source or surface light source, and lamps and lanterns can be designed according to the combined 'secondary light source. Third, artistic light color is the basic element of visual aesthetics and an important means to beautify the living room. The selection of light source directly affects the artistic effect of light, and led shows its advantages in the artistic display of light color; At present, color led products have covered the entire visible spectral range, and have good monochromaticity and high color purity. The combination of red, green and yellow led makes the color and gray scale (16. 7 million colors)The choice of has greater flexibility. Lamps and lanterns are luminous sculptures, and the material form of lamps and lanterns constructed by materials, structures, shapes and textures is also an important means to display art. Led technology makes room lamps combine science and art better organically, breaks the edge frame of traditional lamps and goes beyond the inherent concept of so-called lamp form, the design of lamps and lanterns recognizes, understands and expresses the theme of light from a new perspective on the artistic creativity of visual perception and form. We can more flexibly utilize the advantages of light and dark collocation, the combination of light and color, material and structural design in optical technology to improve the freedom of design to weaken the lighting function of lamps and lanterns, let lamps become a kind of visual art and create comfortable and beautiful lighting artistic effects. For example, translucent synthetic materials and aluminum LED lights similar to candles can be placed on the ground, corners or tables at will, with simple and easy conception, and the visual experience and light experience conveyed by the form, let the lamps become a life full of fun and vitality. Fourth, humanization, there is no doubt that the relationship between light and human is an eternal topic, 'People see the light, I see the light ', it is this classic discourse that has changed the understanding of countless designers. The high level of lamps is the high embodiment of 'shadowless lamp' and humanized lighting. There is no trace of any common lamps in the room, so that people can feel the light but cannot find the light source, it embodies the humanized design that combines light with human life. LED lamps are small in volume and light in weight, and can be combined with LEDs of different light colors into various modules with soft illuminance, which can be installed in the living room at will, the light source of room lighting may come from the ground, wall surface, window sill, furniture, ornaments, etc. Therefore, in the future, room lighting will no longer be limited to a single lamp, but will be transformed from a single lamp lighting to a shadowless lamp with no overall lighting effect. Different light colors and brightness can have different effects on human physiology and psychology. People do not need very bright white light in many cases. Perhaps yellow light or other colors of light are more suitable for physiological and psychological needs. TriColor led can realize continuous transformation and selection of brightness, gray scale and color, making illumination expand from white light in general sense to light of various colors. Therefore, people can according to the overall lighting needs (Such as color, temperature, brightness and direction, etc) To set the lighting effect, realize humanized intelligent control, and create different indoor lighting effects. Even if there are only led luminous ceilings and luminous walls in the living room, people can also understand the environment and life according to their own requirements, scenes and different understandings, select and control the changes of brightness, gray scale and color of light in different space and time, simulate various light environments to guide and improve emotions, and reflect a more humanized lighting environment.
