A considerable number of domestic LED companies have intervened in the market development of LED indoor lighting products. According to the survey, there are a full range of domestic indoor LED lighting fixtures. Commercial LED bulbs, fluorescent lamps, downlights, spotlights and other lamps have been released. Compared with the LED products reported by foreign manufacturers, the current cost performance of LED lighting products has certain advantages.

Although there have been LED lamps to replace traditional lighting fixture application cases. The huge market of indoor lighting has been concerned by LED companies. Many companies are full of confidence in the LED indoor lighting application market. There are many indoor lighting places, and the requirements of lamps in different market segments are often different. The reporter interviewed some industry experts and enterprises and looked forward to more views from everyone.

How LED products enter the indoor lighting market

Professor Fang Zhilie of Fudan University believes that the application of products should be developed from the advantages of LED. LED energy saving, environmental protection, long life, easy dimming and other characteristics are unmatched by traditional light sources, such as incandescent lamps, tungsten halogen lamps have good color rendering, but low efficiency; low-pressure sodium lamps have high efficiency but poor color rendering, LED lighting products can Aiming at the shortcomings of traditional lighting fixtures' light sources, many advantages of traditional LED lighting products can be developed by using LED single item and multiple advantages.

Professor Fang believes that as a lighting source, the basis for judging the start of the market can refer to the important parameter of lighting cost. People generally only pay attention to the initial cost of the light source, and ignore the efficiency, life, maintenance and replacement costs of the light source. The LED light source is superior to the traditional light source. But in the short term, high-end products are still dominated by foreign markets.

Nanjing Henderson Technology Co., Ltd. Chairman Zhou Ming believes that in recent years, with the rapid improvement of LED efficiency and the rapid decline in cost, its advantage in the total cost of ownership of indoor lighting has also begun to emerge, but in terms of indoor general lighting LED The light source is not enough to shake the dominant position of traditional light sources such as compact fluorescent lamps, straight fluorescent lamps, metal halide lamps, etc. This is mainly because the unit lumen cost of the first purchase of LED lamps is still relatively high, and the cost of LED lamps for indoor lighting is still as high as 0.10 ~0.15 yuan/lumen, which is about 3--5 times the cost of traditional light sources, and the price is still a threshold. There is also a need to solve color rendering issues.

In the direction of LED lamp product development, Chairman Zhou Ming believes that it is advisable to replace low-efficiency light sources such as incandescent lamps and halogen lamps and their lamp products, and it is not appropriate to take the risk of replacing large-scale straight-tube fluorescent lamps, high-pressure sodium lamps, and metal halide lamps. Its lighting products. At present, customers on the market have high recognition of LED downlights, LED spotlights, and LED bulbs, and they are mainly used in the field of commercial lighting. With the current price-performance ratio and initial purchase cost of LED lamps, it is still 3~ 5 years.

Japanese LED manufacturers are vaguely ahead

Recently, Japanese media reported that in June 2009, Sharp launched LED bulbs with a price of about 4,000 yen. In December of the same year, Japan’s Orion ELectric launched an 6.6W, total luminous flux of 420lm, which is equivalent to a 60W incandescent lamp. The product is priced at 2480 yen (including tax); this price is close to the price of energy-saving lamps in Japan, which shows that Japanese LED manufacturers have accelerated the pace of cost reduction and performance improvement. The target value of cost reduction for Japanese manufacturers is reduced to 0.5 yen/lm by 2011. The current cost is 1 to 1.5 yen/lm.

Japan has introduced economic policies to promote the popularization of LED bulbs through the reform of the environmental protection point system. It is expected to use a budget of 26.831 billion yen to support the LED lighting industry, promote the popularization of LED bulbs, and promote the replacement of incandescent and energy-saving lamps with LED lamps. The manufacturers have successively released new products of LED bulbs. Through statistics, it is found that the brightness of each product released will be improved, and the number of varieties is also increasing.
