However, what is LED, and how big is its industry prospects? LED is the abbreviation of English light emitting diode. LED does not rely on filament heating to emit light. The energy conversion efficiency is very high. In theory, it can achieve 10% energy consumption of incandescent lamp. Compared with fluorescent lamp, LED can reach 50%. Energy-saving effect, LED is solid package, firm structure, life expectancy of 100,000 hours, 10 times that of fluorescent lamps and 100 times that of incandescent lamps. In terms of environmental protection, LEDs are used instead of fluorescent lamps to avoid secondary pollution of mercury rupture in fluorescent tubes. The China Green Lighting Project Promotion Project Office has conducted a special investigation. China's lighting power consumption is more than 300 billion degrees per year. Replace all incandescent lamps with LEDs or partially replace fluorescent lamps, saving 1/3 of the lighting, which means saving 100 billion kWh. It is equivalent to a total investment of more than 200 billion in the Three Gorges Project's annual power generation. Therefore, LED greatly reduces China's energy consumption, and its significance is very significant. In addition, LED is the most advanced radio and television technology, and can be applied to mobile phones, LCD backlights, buttons, signal devices, large display screens, etc. At the same time, LED light sources are free of ultraviolet light, infrared light and other radiation, and can avoid fluorescent tube rupture. Secondary pollution of mercury spills. An American expert has pointed out that LED semiconductors have completed a revolution in electronics, and the second revolution will be carried out in the field of lighting. As a result, a LED lighting boom swept the world, setting off the "second revolution" in the lighting industry. More experts believe that high-brightness LEDs will be one of the greatest inventions after humans invented incandescent bulbs.
Because of its importance, all countries in the world attach great importance to the R&D and production of LEDs. The “Next Generation Lighting Plan†(NGLI), which was formulated in the United States in 2000, was included in the Energy Act. It is planned to replace 55% with LEDs by 2010. Incandescent lamps and fluorescent lamps form a semiconductor lighting industry market with an annual output value of more than 50 billion US dollars; the EU's "Rainbow Project" was launched in July 2000 to promote LED applications through the EU's special subsidy. In recent years, China's LED product technology innovation and application development capabilities have gradually improved, device reliability research position has become more and more prominent, test technology and standards have become hot spots, all of which mark that China's LED industry has entered a new development. stage. In addition, China has included LED lighting in the national “10th Five-Year Planâ€. At the end of 2003, the state urgently launched the "Semiconductor Lighting Industrialization Technology Development Major Project", and established a semiconductor lighting engineering coordination leading group composed of eight ministries and commissions, and determined that Shenzhen, Dalian, Nanchang and Xiamen five cities are industrial demonstration bases. At present, domestic power supply is tight. Recently, the country has raised electricity prices. High electricity prices directly increase the cost of living for Chinese people. Under this background, the popularity of energy-saving lighting is directly promoted. Some experts predict that by 2010 China's entire LED industry's output value will exceed 100 billion yuan. The LED lighting industry has achieved unprecedented opportunities for development.
(And News Finance original)
Under the expectation of huge industry prospects, stocks with LED concept will have a huge potential, Tongfang shares (600100, stocks) (600100) is such a LED big black horse: Qingxin Optoelectronics Co., Ltd. is the company's LED industry operating entity, own Excellent management team, technical team, MOCVD equipment and accessories with independent property rights, skilled production process, 14mi1 blue LED chip luminous intensity 140-200mcd, luminous efficiency over 731m/W, 40mi1 high-power blue LED chip luminous intensity 3000mcd, The luminous efficiency is 65LM/W, which has reached the advanced level of international industrialization. The company's LED industry chain has been basically mature. At present, there are 8 customers in China, accounting for about 30% of product sales. The current output is in urgent need of improvement. It is expected that domestic demand will reach 60% in the next three years. There are two companies in overseas Korea, one in Malaysia, which currently accounts for 70% of product sales. The domestic LCD TV, computer companies and large screen (height, large size) scale production will be combined with the company's LED business to bring huge development space. The company's LED industry Beijing Airport Base has started construction. It is expected that 15-30 MOCVD equipment production workshops and clean workshops will enter the commissioning phase in August and will enter the production phase in October. Tongfang shares (600100) is undoubtedly a very competitive enterprise in the LED industry. The stock is full of stamina and it is recommended to intervene on dips.
Light bar is another name for Led Strip Light, is named for its shape. Just as Chinese pictograph, whichever shape together with associated material derived. Common title Great Wall lights, LED light bar, LED soft light, light bar, FPC strip lights, etc.
LED Strip Light with conventional and LED light bar is divided into two kinds of flexible LED lights,like ip65 led strip,ip20 led strip,led strip blister, but also generally contain wire connecting with old-fashioned LED lights, such as flat three-wire 4.3W / m, flat four-wire 6.48W / m, flat five lines 8.64W / m light zone.
1, a flexible LED strip light is made using FPC assembled circuit boards, assembled with SMD LED, the thickness of the product is only the thickness of a coin, does not occupy space; common specifications are 30cm long 18 LED, 24 pcs LED and 50cm long 15 LED, 24 Ke LED, 30 pcs LED, etc.
2, LED strip light is made with hard-board PCB circuit board assembly, LED SMD LED helpful for assembly, but also useful for assembly-line LED, depending on the needs of different elements and different. Advantages light bar is relatively easily fixed, processing and installation are more convenient; shortcomings can not be bent, not suitable for irregular place. SMD LED light bar with has 18 LED, 24 LED, 30 pcs LED, 36 LED, 40 pcs LED, etc. Good variety of specifications; with LED line are 18, 24, 36, 48 different specifications.
