Over the past 10 years, LED have undergone great changes in color type, brightness and power . LED plays an unparalleled role in traditional sources of indoor and outdoor lighting with its amazing and gratifying application in the city. The life is up to 100,000 hours, which means working eight hours a day, you can have 35 years of maintenance-free. Low voltage operation, almost 100% light output, low to zero output, the dimmer can be combined thousands of light color, and the light emitting area can be very small, can be made into 1 mm2. After the second optical design, the light achieved the desired light intensity distribution. The rapid development of LED lighting technology will bring a new design and application possibilities, many of the traditional light source are impossible to achieve.
The characteristics of LED
Today it seems that the world's eyes are focused on this new LED light source, known as the 21st century green lighting products, and even the majority of people predicted that the future will replace the traditional light sources. Because it has a long life, short start-up time , solid structure, energy saving, luminous body near point sources, thin lamps, lighting large choice of materials, no need to add a reflector, low pressure, no ultraviolet radiation, the use of more safety features in the public environment. Coupled with the LED light source can have mercury-free, but also has important implications for environmental protection and energy conservation.
Applications in lighting engineering direction
1. The building exterior lighting
Buildings projected is simply using the control beam angle round and square head shape Floodlights, it is entirely consistent with the traditional floodlights concept. However, due to the LED light source is small and thin, linear projection lamps research will undoubtedly become a highlight LED projection lamp, because many of the buildings is no place to put overhangs traditional floodlight. Now linear projection lamp is easy to install, can be installed horizontally and vertically, better integration with the building surface, bringing new lighting for lighting designers, expanding the creative space, and will have lighting modern architecture and historic buildings a huge impact.
2. Landscape Lighting
The traditional LED light fixtures are mostly glass envelope, but LED is unlike, it can work which combined with urban street furniture. Also it can be illuminated in the city such as paths, stairs, decks, waterfront, garden. For flowers or low shrubs, you can use the LED as a light source for illumination. Concealed LED Spotlights are particularly favored. Fixed end can be designed for plug-in, based on the height of plant growth, and to facilitate adjustment.
LED lighting is a most promising 21st century high-tech field. As a new and efficient solid light source, has the significant advantage with long life, energy saving, environmental protection, etc., which will be the another leap forward in the history of lighting. Epitaxial semiconductor lighting products production, chip manufacturing, device packaging, and several other aspects of integrated application has initially formed a relatively complete industrial chain, but the function of LED lighting, there are many constraints to achieve white light illumination. Therefore, in the present case, the LED lighting product development and design placed the following wish:
1. Meet the individual needs of people
Modular LED for lighting design brings convenience by designer fully rational layout, the LED is in good working condition. LED products meet the individual lighting which is dwarfed by traditional light sources, LED products in the form of diversification will reach unprecedented levels. Therefore, the biggest challenge for the development of LED products personalized with designers all LED lighting supplier must be faced.
2. Low-power LED lighting design
The low-power LED products is very usefully in landscape lighting. The angle of light is small, directional, and can be used for local accent lighting. It is enough to give designers a range of options should also be aesthetically pleasing appearance requirements. It's safe to say that, LED lighting will lead the fashion and trendy in the future.
3. Environmental protection and energy conservation
The concept of green lighting is the world follow the eco-design targets. If you can use LED and solar together, it will expand the scope and application of LED options.
4. High-power, high-efficiency, high color rendering white LED lighting product development
LED lighting in the area of use is still limited by technical standards and prices, the current difficulties in the field of LED lighting applications, LED white light efficiency is not high, the power is not big, expensive. But the prospects for the development of promising white LED, high luminous efficiency, high power single output.
