Follow the LED lighting companies need to be cautious investment

"To LED for the traffic signal lamp, light source lamp decoration has been widely used in China, more and more small and medium-sized enterprises have tasted the sweetness of energy, have joined the industry, to the development of increasingly fierce competition today, so we choose another way -- the production of high-power semiconductor lighting products. "The general manager of Shenzhen efei Lighting Co. Ltd. Huang Jiutai said recently.

High power LED lighting products in the urban landscape market. At present, many large semiconductor lighting manufacturers have the same idea with Huang Jiutai.

According to the reporter, Tianyi Science and Technology (600370), Jiangxi LIAN (600363), fangea (000055), Fujian (600203), Hangzhou Furi Silan Limited by Share Ltd (600460), shares the same side (600100) of six domestic listed companies are facing increased production costs, lower profits and other new problems, have to seek a new way, the new profit point in large power semiconductor lighting industry.

Enterprises have launched large projects

High power lighting equipment is now mainly used for road lighting, its price is 3 times higher than ordinary lighting, but can save energy by 60%. Government procurement accounts for a considerable part of the lighting energy saving enterprises as we can enjoy the country's energy conservation policy, so we must seize this excellent market opportunities. Fujian Furi Electronics Limited by Share Ltd a marketing staff told reporters.

One person Jiangxi LIAN also said that the LED company as the leading industry, the production scale is small, low-end products than the major, the current inventory amount is still too large, is also faced with rising raw material prices, labor costs, industry competition and other difficulties. Based on this, the company will be the power type high brightness LED package and LCD backlight, special lighting, landscape lighting application products as a breakthrough, the formation of power devices, chip, semiconductor lighting and lighting products industry. It is understood that the company invested 199 million yuan last year to carry out a high brightness, high brightness and chip LED technology transformation, has been completed.

Reporters from the recently released annual report shares the same side of the learned, the company completed 5 LED production line construction last year, and has formed an annual output of high power blue LED chip production capacity of 400 million, two and 15 LED production line construction is underway. Investors need to think calmly

At present, the development and production of LED as the light source of road lighting production enterprises more and more, preliminary statistics have hundreds of enterprises.

"This is not a wise choice for businesses. "Deputy Secretary General China Lighting Appliance Association Dou Linping said," there may be some business decision-makers think, put into production as soon as possible 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. Scientific, reasonable and timely development and production of light emitting characteristics and LED matching lamps, to avoid blind investment. Investors also think calmly, in order to correctly grasp the direction of development. "

In this regard, there are technical personnel, said 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 lamps light source enterprises, and have a good understanding and Study on Luminescence 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 radiation surface. But the lighting effect is not ideal.

The source further explained that, compared with the ordinary high-pressure sodium lamp or metal halide lamp, LED light source light angle is smaller, so the greater the brightness of the effective illumination, a stronger sense of direction, so there are advantages in local lighting. Because of this, LED can achieve the goal of energy saving to a certain extent.

However, when the LED light source is applied to the surface of the road, the problem becomes apparent. Because there are provisions of the distance between each pole lamp, because each light emitting angle is small, the light is concentrated between the two parts of the lamp brightness significantly darker than the light, which is very unfavorable for road lighting, easily lead to accidents.

Experts remind that the current level of technology, many companies can not make the production cost significantly decreased, plans to launch LED high frequency lighting products companies need to choose a good time and investment. Now there is a tendency to overheat investment LED products, enterprises should start from the improvement of technical level, to avoid blind investment behavior.
