How LED products enter the indoor lighting market
A large number of domestic LED manufacturers have been involved in the market development of LED indoor lighting products. According to the survey, the domestic indoor LED lighting fixtures are complete. There are already commercial LED bulbs, fluorescent lamps, downlights, spotlights and other lamps available. Compared with the LED products reported by foreign manufacturers, the current LED lighting products have certain advantages in cost performance.
Although there are already LED lights to replace the traditional lighting applications. The huge market for indoor lighting has been paid attention to by LED companies. Many companies have full confidence in the LED indoor lighting application market. There are many indoor lighting places, and different market segments often have different requirements for lamps. The reporter interviewed some industry experts and enterprises, and I look forward to more opinions...
Japanese LED manufacturers loomed in front
Recently, Japanese media reported that in June 2009, Sharp introduced LED bulbs with a price of around 4,000 yen. In December of the same year, Japan's OrionELectric introduced a 6.6W, total luminous flux of 420lm, equivalent to 60W incandescent lamps. The product, priced at 2,480 yen (including tax); this price is already close to the price of energy-saving lamps in Japan, showing that Japanese LED manufacturers have accelerated the pace of cutting costs and improving performance. The target value of cost reduction for Japanese manufacturers fell 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 points system. It is estimated that the budget of 268.3 billion yen will be used to support the LED lighting industry, promote the popularization of LED bulbs, and promote the replacement of incandescent lamps and energy-saving lamps with LED lamps. Manufacturers have successively released new LED bulbs. Through statistics, it is found that the brightness of each product will be improved and the number of varieties will increase.
How LED products enter the indoor lighting market
Professor Fang Zhilie from Fudan University believes that it is necessary to develop application products 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, good color rendering, but low efficiency; low pressure sodium lamps, high efficiency, poor color rendering, LED lighting products can In view of the shortcomings of the traditional lighting fixtures, many new LEDs that are superior to traditional lighting products can be developed by using LED single items and multiple advantages.
Professor Fang believes that as an illumination source, the basis for determining the market start-up can refer to the important parameter of lighting cost. People generally only pay attention to the initial cost of the light source, while ignoring the efficiency, life, maintenance and replacement costs of the light source, the LED light source is superior to the traditional light source. However, in the short term, high-end products are mainly based on foreign markets.
The chairman of Nanjing Handerson Technology Co., Ltd. Zhou Ming believes that with the rapid improvement of LED efficiency and the rapid decline of cost in recent years, its advantages in the total cost of indoor lighting are also beginning to emerge, but in the indoor general lighting LED The light source is not enough to shake the main position of traditional fluorescent lamps such as compact fluorescent lamps, straight tube fluorescent lamps, metal halide lamps, etc., 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 / lumens, is about 3 to 5 times the cost of traditional light source lamps, the price is still a threshold. There is also a need to address the issue of color rendering.
In the direction of LED lighting product development, Chairman Zhou Ming believes that it is better to replace the inefficient light source such as incandescent lamp and halogen lamp and its lighting products. It is not advisable to take a large-scale replacement of high-efficiency light sources such as straight tube fluorescent lamps, high-pressure sodium lamps and metal halide lamps. Its lighting products. Nowadays, customers on the market have high recognition of LED downlights, LED spotlights and LED bulbs. They are mainly used in commercial lighting. With the current cost performance and initial purchase cost of LED lamps, it is necessary to enter the home application in large scale. 5 years.
Tang Shiquan, chairman of Taiwan Tangshi Lighting, said that the luminous efficiency of LED is steadily increasing. At present, the luminous efficiency of 120lm/W makes LED light source can replace traditional energy-saving lamps. In the next few years, the LED indoor lighting market will surely expand with the further improvement of the luminous efficiency of LED light sources. When its luminous efficiency exceeds 150lm/W, LED lighting products can fully meet the requirements of most indoor lighting environments.
Dr. Liang Bingwen, Chairman of Suzhou Najing Technology Co., Ltd. believes that the biggest weakness of LED as a lighting product compared with traditional light sources is that the luminous flux and cost are almost linear. This makes the LED light source costly in the high luminous flux range, and the cost performance is very low. Therefore, in the early stage of market promotion, the application market of low luminous flux should be considered first, such as the application demand of 200-800 lumens. The range of this luminous flux corresponds to an electrical power of about 3-15 W at the current level of LED light efficiency, and the lamp has a high cost performance.
Wu Wenfeng, president of Yayi Lighting, also said that LED has a larger space for indoor lighting development and is more suitable for the characteristics of the product itself. It is expected that with the price reduction, technology advancement and product maturity, LED is expected to be in 3 years or so. Large-scale entry into the field of indoor general lighting.
Gong Weibin, general manager of Shenzhen Ruifeng Photoelectric Co., Ltd. said that with the steady increase in the market share of LED lighting, the scale will reach 5% of the indoor lighting market within three years.
N-net 24 Ports Poe Switch series includes the fast Ethernet series and gigabit series, also the managed and unmanaged series. It supports 24 ports PoE ports with up to 30W PoE output per port and total power budget 440W(Built-in power supply). PoE is especially suitable for devices that are far from power outlets or when users want to minimize the clutter of extra cables as power is supplied via the Ethernet cables themselves.
This series enables users to easily connect and supply power to PoE-capable devices such as wireless Access Points (APs), IP cameras, and IP phones. It can also connect other Ethernet devices like computers, printers, and Network Attached Storage (NAS) to fit into any type of network application.
4 Combo uplink ports means businesses can increase their network bandwidth via wired speed while offering redundancy so voice and surveillance data are transferred reliably. The combo design can increase bandwidth by offering two Gigabit copper or fiber connections, giving administrators more options for expansion.
