Cool thinking behind LED investment fever

In recent years, the development and application of LED (light-emitting diode) lighting products have attracted wide attention in the field of lighting at home and abroad. Industry experts generally believe that the application of LED in the field of lighting has a very broad prospects, huge space for development. With the rise of global economic integration, international LED lighting industry is to China industry echelon transfer, which makes the LED lighting industry Chinese has achieved leapfrog development potential.

LED lighting great prospects, quickly led to the domestic LED lighting investment boom, many companies have launched LED lighting production line, put a lot of money, and actively seize market share. However, in the face of the LED stock investment boom, industry experts believe that although as a new energy-saving lighting products, the development of space LED is very large, but for the development route and direction of investment and how to implement the fast group breakthrough problems such as the LED lighting industry, enterprises and investors need to calm thinking, to correctly grasp the direction of development.

LED remains as a road lighting defect

China Lighting Association Deputy Secretary General Dou Linping believes that the current market there is a tendency to overheat investment in LED products, some companies on the production and investment of LED products more blind. For example, at present, the company launched a resurgence in the production of LED road lighting boom. He believes that with LED as traffic lights, landscape lighting, decorative lighting lamp light source has been widely used in China, its technology is more mature, but as road lighting, LED there are still some technical problems to solve urgently.

Dou Linping said that the road lighting is a very high lighting requirements of the product, the quality of the road lighting effect, the level of lighting technical indicators, will directly affect the driver's line of sight and driving safety. Most of the current development and production of LED road lamp light source of the enterprise, and not very well understood and luminescent properties of LED, which is simply the original road lamp shell with LED light source, or simply LED tile on the lamp and folded into an angle to increase the irradiation surface the lighting effect is not ideal.

Compared with the ordinary high-pressure sodium lamp or metal halide lamp, LED light emitting angle is small, so the effective irradiation face greater brightness, strong sense of direction, so there are advantages in local lighting, it is precisely because of this, LED can achieve energy saving in some degree. However, LED is applied to the road lighting, the salience of the issue: there are provisions of the distance between each street lamp poles, and because each light emitting angle is small, light, LED lamp brightness between the two part of the obvious dark to light, the road lighting is very unfavorable and it is easy to cause the safety accident. In addition, LED other than ordinary light color temperature high, reached about 6000K, higher the temperature will in visual effect make people feel the "cold", can let a person produce visual error, the driver is not conducive to accurate judgment of things, there are security risks. If the color temperature is reduced, the brightness of the light source is changed. In short, Dou Linping believes that as the LED road light, the intensity and uniformity of illuminance, luminance, luminance uniformity, glare, color, light and are not well resolved, and it is because of these problems, the country now rarely has area should use LED as road lighting, even some city tries to use in some way as LED road lighting and did not get good results, only the last change.

At the same time, the development and production of LED as the light source of road lighting manufacturers are more and more, preliminary statistics have hundreds of enterprises, its propaganda and promotion momentum is fierce, but also have invested a huge amount of money. Dou Linping admitted that this is not a wise choice for the enterprise. Some companies may be the decision makers believe that early production can seize part of the market share. But the production enterprises still have to pay more attention to the development of LED light source technology, investment research strength, according to the technical level of the light source, scientific and reasonable, timely development and production of lamps matching with LED luminescence characteristics, should not blind investment.

Long period of investment long upstream technology monopoly

The industry believes that, LED lighting industry is a capital intensive industries, investment intensity, high technical difficulty. At present, some of the funds outside the industry optimistic about the market, one after another into the LED lighting industry, contribute to the formation of the scale of the industry, but these companies should be prepared to invest in LED is difficult to quickly see market benefits. First, from the perspective of the industrial chain, from the chip to the package to the two application, the focus of each link and control points are completely different, the front is very long. Secondly, the expected return of high investment funds often choose to do this part of the upper reaches of the chip, high investment, high risk, the risk of technology and talent is particularly large, so do the chip is difficult to see the benefit in the short term, even to do the loss of psychological preparation. Investment in packaging and downstream products to do a little risk, but few investors are willing to do low profit products. In fact, in the LED industry, if there is no accumulation of experience and internal integration, it can only do small profit products. In the lighting market, the main problem is that the cost of technology research, market potential ability, although large, but the technology is mature, speed is not too fast, which also leads to a mature market speed is not too fast, although the rapid expansion of applications, but the real scale of the market is more difficult, so even if there is money injection is also difficult to see immediate results. from
