LED lighting capture the market of the three stages of strategic development

Light green, small size, high reliability and other features increasingly prominent. The higher the tariffs, the use of longer places of business applications, LED lights quickly became the new darling of the market. As the use of LED lighting, LED market in several stages.
LED lamps to replace accepted
This phase refers to the LED lamps in the early stages of development, mainly reflecting its high light efficiency (energy consumption), and long life. Because the price was high, so at this stage mainly for business according to the market. Customers have a process to accept, is to use the habits and appearance of the transition and acceptance. Consistent with the traditional light sources in use case, LED lighting reflects the saving, longevity and other characteristics of the market makes it relatively easy to accept the high price. Especially in commercial applications. The quality of various manufacturers to fight the price advantage.
LED lamps utility model
In the last phase, based on the market for LED lighting products have a certain amount of recognition and acceptance. Green LED lamps, small size, high reliability and other features increasingly prominent. Thus developed a series of completely different from the traditional light source applications of the product will be popular. Lighting industry will be a more open space for development. Light is no longer only have a lighting effect, making it more appropriate for people of varied work life bit by bit. The company is designed to fight the application advantage.
LED lighting intelligent control
From home to office, from the road to the tunnel, from cars to walking, from the auxiliary lighting to the main lighting, with intelligent control of LED lighting systems will bring a higher level of human services. LED lighting products industry will also be made to design products to provide total solution process. With things such as the development of new technologies, LED as the semiconductor industry, high-speed trains will also catch this tour, to play its high controllability characteristics.
Initially dominated by monochromatic LED, although the power is small, the price is high, but its high reliability, controlled, small volume, so the market is the rise of the first electronic device indicator. Market for LED lighting products have a certain recognition and acceptance. With the gradual development of LED lighting, auxiliary lighting in the lighting project and other public places, LED light gradually replace some of the traditional products.

LED light failure definition and influencing factors

White LED current is a major problem facing the problem of life, due to the price of white LED is still very high, in order to gain a foothold in the lighting market, allowing users to both power and money, we must rely on long-life and savings in electricity to make light of high prices. Now, the white LED life situation makes it difficult to do this.
Normal use of terms from the LED, the most important factor affecting the life of LED is hot. Heat source, a material's resistance in the normal power generated by Joule heat, PN junction heat generated, as well as the parasitic resistance caused by process Joule heat generated, and the resulting light is attracted heat. The accumulation of heat makes the temperature, temperature makes the chip performance degradation, degradation of aging and degeneration.
1 What is the LED light failure
LED light decay products is light in the transmission of the signal weakened, and at this stage the global LED manufacturers who decline to make light of the LED lights are different, there are also high-power LED light failure, and this is directly related to temperature, the main by the chip, phosphor and packaging technologies decision. Currently, the white LED on the market may decline to its light commercial lighting into one of the most important issue.
2, the impact of two factors LED light failure
1) LED LED chip quality problems using good body, brightness decay quickly. Production process defects, LED chips heat can not export a good foot from the PIN, the chip temperature is too high to make the LED chip attenuation increased.
2) The conditions of use
LED constant current driver, there are some LED drivers of the LED using voltage attenuation over. Drive current is greater than the rated drive conditions. In fact, lead to bad light LED products for many reasons, the most important thing is the hot issue, although many manufacturers in the sub-products do not particularly pay attention to heat issues, but these secondary long-term use LED products, the lumen of a focus than the heat LED products to be high. The thermal resistance of LED chip itself, the impact of silver plastic, the cooling effect of the substrate and colloidal and gold also have a relationship with the bad light.

LED industry prospects bright

Quanzhou's LED industry is still in its infancy, the government should strengthen guidance and training technical personnel to drive the formation of brand and chain, LED industry a bright future. "Yesterday, professor at Peking University, Chinese Academy of Sciences Gan Zi-Zhao interview with this reporter said.
Gan Zi-Zhao Academy has more than 70 years old, still eyed, hale and hearty. In the interview with this reporter, he is always smiling, amiable. Mention the study of LED technology and solar PV industry, Gan Zi-Zhao talking about. He believes that rapid development of LED lights in recent years, in 2015 -2020 period, the domestic is likely to achieve most of the LED lighting in general lighting applications. LED lighting, saving 50% over incandescent lighting, extensive use in general lighting, the electricity the entire society will be able to save more than 5%.
In recent years, due to the rapid development of optoelectronics industry in Quanzhou, driving the LED industry chain downstream of the rapid follow-up and rapid spread. Gan Zi-Zhao booming economic development of Quanzhou vitality appreciation for me. He said, Quanzhou, LED industry has just started, the government should actively guide the orderly and disorderly competition into the market, cultivating brands and the Group; should make great efforts to improve the technical level, training technical personnel, and technological innovation to give incentives and subsidies; should pay attention to solid-state lighting development opportunities, such as solid-state lighting can be applied to the cultural and creative industries, pharmaceutical industries, mechanical and electrical industries.

Three reasons for expensive LED lighting

The prospects for the current, LED lights for the average consumer price is still too expensive, difficult to consumption since. According to industry analysts, LED lighting is expensive, mainly in the following areas.
First, LED products, thermal difficult. So this feature, so manufacturers in the production of LED products, they tend to spend a certain amount of cost in the production of parts on the radiator. Therefore, to reduce the price of LED products that can reduce cooling costs in this regard from the start.
Second, because power is the weakest link in LED products, LED products, which accounted for 20% of all costs, so if the power LED application manufacturers to improve the quality of management devices, power management, cost control about 5% -10%, so to a large extent, reduce the cost of LED products cost.
Finally, the domestic LED industry is not their core technology. Many high-end LED technology in the hands of European and American countries, researchers, therefore, the domestic LED products are just products occupy a minimum share of profits. Because with the continuous development of LED chips and development of its extensive use of the overall cost of LED products will fall, but the present, the number of LED chips using imported technology, resulting in cost is very costly.

LED lighting-to-date security standards

Currently on the market a wide range of energy-saving lamps, and more technologically advanced and more environmentally friendly to calculate the energy-saving LED lights. Data display, LED energy-saving 80% energy saving than incandescent lamps, fluorescent energy-saving lamps over 50%. LED lamps are energy saving, environmental protection advantages in lighting industry has become a major trend. The obvious advantage of energy-saving LED lamps can be reflected from the following aspects:
1 low-power, low power consumption: In general, LED display operating voltage is 2 to 3.6V, operating current is 0.02 to 0.03A. That is to say: it does not exceed power consumption of 0.1W;
2 Small: LED energy-saving lamps is basically a small chip is encapsulated in epoxy;
3 long life: the right current and voltage, up to 100,000 hours of their life, almost no maintenance. In addition, LED energy saving lamps are completely epoxy resin, it is more than light bulbs and fluorescent tubes are strong, light body and no loose parts, easy to damage;
4 high-brightness, low-calorie: ordinary incandescent and halogen lighting, although cheap, but the light efficiency is low, due to the thermal effect of light and vain power; LED lamps as lighting lamps, not only high luminous efficiency, and cold produce almost no heat source power;
5 Green: RGB LED light are made by the non-toxic materials, unlike fluorescent lamps containing mercury can cause pollution, but also can be recycled;
6.LED also has energy-saving lamps flicker, applicability, high stability, short response time, etc.;
As LED technology and products used by traditional lamps with different properties have been, so the current safety standards of general lighting is obviously not applicable. In this note about the current safety testing LED lighting requirements (to UL standards, for example).
