From shopping malls to rolling ladder lights to scattered LED wall lights, as well as high-end goods, such as jewelry, watches and other counter lights, even in the mall lighting, various LED lights have quietly changed. Not only did this change occur in large public buildings such as shopping malls, hotels, and office buildings.

Rapid development of commercial lighting

LED is a new light source with strong vitality, which is closely related to our life.

China's commercial LED lighting market is moving from concept to real application.

It can be said that LED light sources can be seen everywhere. Whether it is mobile phone, TV, computer or night lighting, street lights, tunnel lights can see the LED light source graphics. The architectural lighting and night lighting design of the Shanghai World Expo Stadium uses LED as the light source and LED light source as the material. LED lighting is progressing more rapidly in indoor lighting.

The conversion efficiency of inc incandescent lamp conversion efficiency is only 5%. At present, the conversion efficiency of LED lamps is generally 25% to 40%, which is much higher than the conversion efficiency of incandescent lamps. LEDs have been widely used in many places, not traditional light sources. As people's awareness of energy conservation and environmental protection has increased, the government has begun to limit the use of incandescent lamps, with high energy consumption and high pollution. The phasing out of incandescent lamps has become a consensus. The elimination of incandescent lamps is taking place around the world, and China is also doing it on a large scale. China's phasing out of incandescent lamps and accelerating the promotion of energy-saving lamps is a concrete manifestation. China's phasing out of incandescent lamps and accelerating the promotion of energy-saving lamps is a three-year project. National Development and Reform Commission (NDRC) and UNDP (UNDP) is jointly implemented by the National Development and Reform Commission (NDRC) and the United Nations Development Programme (UNDP) to reduce the carbon emissions from the use of incandescent lamps. The lamps are about 4.4 million tons per year.

Tang Guoqing, general manager of CRIE China Market, believes that the transition from traditional lighting to LED lighting has spread around the world. In March of this year, a famous Japanese company stopped producing ordinary incandescent bulbs and expanded its LED lighting business. Tang Guoqing believes that LED can drive the reform of lighting and benefit from the following aspects: First, excellent environmental protection, second, high light efficiency, third is good color, more comfortable and safe night life, and fourth is CO. Lor shows that high color saturation is an indispensable part of urban beautification; the fifth is flexibility. More user-friendly design and enjoyment of the beauty of lighting has become a new focus.

Pay attention to and face up to standard issues

Starting from the most urgent and influential industrial development standards, we will develop as soon as possible

Emphasize product consistency, reliability and color rendering.

Indoor lighting is the most suitable market space for LED development in the future. However, the LED lighting market is not very mature at this stage, the standards of various manufacturers are not the same, the domestic LED lighting standards have not yet been introduced, especially the application of LED lights in indoor lighting. The requirements for the LED light source are: high light efficiency, low heat resistance, high color rendering, long life, low cost, integrated design, and the like. The interior lighting of LED companies poses a huge challenge.

Liang Bingwen said that the standardization of products is very important, and the industry without standards is an immature industry. It should be said that our standard setting lags behind the development of products and markets, which is very regrettable. In this regard, we should learn from the advanced experience of the United States and other countries, starting with the most urgent and significant impact on industrial development, and quickly formulating some standards or norms that contribute to industrial development, so that industry can enter. Companies can learn from and refer to, rather than spending a lot of time on standards that are not urgently needed in the industry, not more. I have done very well from the beginning, very good. "I personally think that substrates and extension standards are not very urgent at the moment, they may be outdated, they are developed. It should be clear that what is the most urgent standard for industrial development, for example, in the United States, the ENERGY STAR standard for LED lighting The development of the industry is important, so they quickly organized an LED lighting standard. In this way, there are no major obstacles in product promotion, and issues related to the market, such as government subsidies and support. We should study and learn from this good. Experience." Liang Bingwen suggested.

In addition, product consistency, reliability and color rendering should be emphasized. Liang Bingwen said that if LED lighting is entering the field of indoor lighting, indicators such as consistency and reliability of products and color display need to be improved. If the light bulb is different, it becomes a "lantern". The color rendering index should be greater than 85, otherwise it is difficult to call it a high-quality light source and cannot match its price.

Transforming the appropriate LED lighting system is imminent

Correctly check the cost of LEDs and establish a lighting system suitable for LED lighting.

At present, the cost performance of LED has obvious advantages over some traditional light sources.

When it comes to the promotion barriers of LED lighting products, high costs seem to be the most widely used word. Some experts believe that it is imperative to correctly detect the cost of LEDs and establish a lighting system suitable for LED lighting. The construction industry needs to redesign and design the lighting power system. In LED lighting products, the housing, power supply system (power conversion), cooling system, etc. account for about 50% of the cost. The cost of this part should not be the cost of semiconductor lighting itself. In the future, with the advancement of chip technology, the proportion of peripheral power systems will become larger and larger. It is predicted that it will account for more than 70%. If this problem can not be solved at all, it will seriously hinder the pace of semiconductor lighting products entering thousands of households.

However, the biggest problem encountered in the current commercialization of LED lighting is cost, especially the initial purchase cost. This is also the issue of the listing of other new technology products. At present, the price of LED light source is almost 3~10 times that of traditional light source, and some even higher. Users are very difficult to accept. Although LED has the characteristics of energy saving, environmental protection and long life, from the perspective of overall cost, the price of LED has obvious advantages compared with traditional light source, but the purchasing power of ordinary people and the recognition of L. ED sources are limited and consumers are very sensitive to the initial purchase price. This has brought great difficulties to the promotion of LED lighting. Liang Bingwen believes that to solve this problem, we must first reduce costs through technological innovation, modularization, standardization and batch upgrades. Second, the government should give some support and subsidies to LED lighting products to enter the mass market as soon as possible. In addition, it is very important to win the favor and favor of customers with new shape design and other added value.
