Rising proportion of LED lighting applications opens a new era of green building

LED building lighting is a nightscape lighting method that integrates LED light sources or lamps with building facades, indoor space, landscape elements and components. Compared with the general lighting market, architectural lighting is a more professional application field, which requires LED lighting to be coordinated with architectural landscape, various lighting design schemes suitable for building structure and style should be provided according to local conditions. According to the survey data of LEDinside, the scale of LED building lighting market in 2012 was about 31. 9. 1 billion US dollars, accounting for about of the overall LED lighting market. Moreover, due to the various light colors, easy design, environmental protection and energy saving of LED, this makes the architectural lighting market have a higher acceptance of LED, a lower sensitivity to product prices, and a faster market popularity. At the same time, there are still many obstacles in the development of the general LED lighting market, which also makes the LED building lighting market another important growth highlight expected by the industry. The types of LED lamps involved in building lighting are usually various, including LED light bands and LED digital tubes commonly used in contour lighting; LED floodlights, floodlights, embedded lights and wall washing lights commonly used in wall lighting; LED tile lamp combined with ancient architectural modeling; Water lamps for square pools and fountains; Underground lamp, lawn lamp; As well as a variety of indoor lighting and so on. On the premise that governments of various countries vigorously advocate green buildings, the energy-saving advantages brought by LED lighting have been paid more and more attention, and the application proportion is increasing significantly, but on the other hand, an urgent problem faced by LED architectural lighting is: how to get rid of the simple design processing such as using light to hook edges and jump, but to integrate LED lighting with artistic creativity. This not only requires lighting designers to further master the technical characteristics of LED; At the same time, manufacturers in different industries in the LED industry chain should make concerted efforts to provide higher quality products and technologies to support according to specific market demands. Speaking of the demand characteristics of the building lighting market, NXP Semiconductors (Shanghai) Zhang Weichao, marketing manager of lighting products in greater China region of the limited company, concluded that the specific demand for LED lighting products in the architectural lighting market includes reducing color temperature deviation, improving the matching of light output and other light sources, energy conservation and environmental protection, saving customer use and maintenance costs; In addition, in terms of performance indexes, there are also requirements for input and output voltage and current parameters of products, various safety and efficacy requirements, etc; It also requires that the heat dissipation performance, reliability and system life of the product should be improved, and the time to market of the product should be shortened.
