With the continuous development of LED lighting technology, and promote LED lighting used in more industries and situations, including indoor commercial lighting has become the future development goals of many companies in the industry, because indo or lighting is recognized as an important future direction of development. According to degree of attention to the point of view of market conditions and the state of the LED industry, LED industry standards is imperative, indoor LED lighting standard is to achieve replacement purposes, to meet the lighting requirements by reference to the size of the structure of the traditional lamp form, the form of light, light and other requirements for the preparation of LED lighting standards, making the LED interior lighting to the inevitable need to move closer to the form of the traditional lamp. Therefore, the next two years of indoor LED lighting development will be affected by the impact of traditional lighting.
In fact, the shape of traditional lamps and lighting is caused due to technical limitations of conventional light sources, LED light source than conventional lighting, there are many features and advantages of LED lighting performance and progress, such as the continuous improvement of luminous efficiency, chip withstand temperatures continue to increase. LED light source in lighting, more space for development, in many ways to subvert the raison d\\ etre of the traditional lighting of LED lighting should have its own way of lighting can be integrated into the more creative to meet the lighting needs and aesthetic needs of the modern man. If we blindly move closer to the traditional lamp, it is likely not play the advantages of LED, but the advantages of LED buried.
Continuous social and economic development, people who have a higher standard of living and lifestyle, lamps not only to meet the basic needs of the lighting is so simple, it is hoped that lighting can bring more life to enjoy a more personalized, humane and intelligent. High quality lighting is increasingly subject to the attention of the industry, the increasingly stringent requirements of the degree of control, uniformity, glare, color rendering index, color temperature and other technology index. The use of different places, different functions, different size spaces, different decorative appearance requirements, determine a wide variety of indoor lighting, different types of light distribution, a higher demand on the future of LED indoor lighting.
LED lamps as a replacement product, of course, we need to meet the size requirements of traditional lamps or light products, performance parameters and light distribution requirements. For example, the bulb light over 270 ° angle of light to better meet the requirements, or installed in the space of lamps or lighting will result in half bright and half dark drawbacks. The use of downlights, in order to achieve the irradiated surface of the illumination uniformity of the distribution curve is similar to the bat wing.
Direct light diffusion plate, almost similar to the Lambertian light distribution, the irradiated surface bright as the center, surrounded by dark, difficult to meet the entire space of the irradiated surface of the illumination uniformity, resulting in poor lighting.
LED downlight to meet the traditional lamp lighting effects can be achieved, should be used in the form of the reflector cup to meet the light distribution requirements, of course, using the point light source mixing and then through the reflector cup is a way, but the COB package reflector, so efficient, avoiding the light loss caused by point source mixing.
For example, replacement grille of almost all panel lights, point source into surface light source, the idea is right, but this form of the panel lights are also some problems. ; The light is low, the light guide plate of the guide light reflective film and screen printing outlets, light uniformity, the light diffusion plate light, this form of light extraction efficiency can reach 70% good. Second, the panel lights similar to a Lambertian light distribution, for the illumination 300LUX or 500LUX need to meet the lighting requirements in the actual lighting effects, glare control curve did not meet the lighting requirements. Combined with the hard cost of the light guide plate is difficult to reduce lead to the high price of lighting will not be able to adapt to marketing.
Spotlights products, the COB + reflector cup is the leading direction, point source + lens will gradually be abandoned.
LED interior lighting technology development needs to consider many factors, interior lighting design requires a different color temperature, different sense of light, different color lamps to enrich the broad horizon, space interface properties require different lighting design. In short, the development of LED indoor lighting long way to go, Wu Jiang from top to bottom.
