China's LED industry is faltering start: the price is still too high popularity time

LED (light emitting diode) light source has been used in lighting, household appliances, automobile and solar energy industry for many years. It is predicted that in 2010 the overall size of the LED industry chain will reach about 80 billion yuan.

However, does it really have the strength to compete with existing products?

Such LED "LED" technology is essentially a kind of semiconductor lighting technology, light emitting material as the semiconductor chip, directly into electrical energy into light energy.

In the field of color TV applications, from last year, Hisense, TCL, SKYWORTH, Samsung, SHARP have produced a variety of LED tv. This kind of TV display is still liquid crystal, qualitative change is the backlight from the CCFL cold cathode fluorescent tube for LED".

The reporter saw in the Suning Appliance, a foreign TV brands showcase, LCD TV with LED backlight source from the color, brightness and clarity is persuasive: 6 color TV sets flash while playing the theme for the green leaf blade LED TV picture, "" fresh green.

Part of the LED TV is also very thin. Some of the thickness of the product is half of the ordinary liquid crystal, there are test reports that Konka, Hisense and SKYWORTH thickness can even thin to 1.9 cm ~2.2 cm.

Another feature of LED is energy saving. Write a leaflet CBN reporters get on the power consumption of a foreign brand color TV 46 inches and 40 inches LED 169 watts and 139 watts; but the other LCD TV power consumption up to 269 watts and 193 watts, the energy consumption of 50% and 40% higher than the former.

Sanan optoelectronics Secretary Yi Shengze told the CBN LED lamp is very power. In general, the LED lamp power consumption is 1/10 incandescent lamp, fluorescent lamp more than 1/2.

In Shanghai City Lighting City, a LED lamp dealers out containing 12 small particles from the cup on the counter, "its power consumption is 2 watts, similar energy-saving lamps currently selling up to 5 to 8 watts. "Another operating lamp with seller surnamed Yu said the boss, red and blue LED light of 1 meters with a power consumption of 3 watts, the power consumption of ordinary lights up to 20 watts. "Moreover, the use of ordinary light band is very short, two or three months without electricity. LED lamp belt can have 1 years of service life. I said the boss.

Yi Shengze also told reporters that the actual maximum LED lamp life of up to 60 thousand ~7 million hours, is about 10 times of the fluorescent lamp, LED lamp and low voltage, high safety, light weight, short response time, rich color adjustable, does not contain harmful elements. Therefore, a lot of electronic information, automobile traffic signals will be used LED. "

Exorbitant price

However, the price of LED products is really high.

Take LCD LED TV, Suning Appliance in a 55 inch TCL brand LED TV price of up to $24 thousand, while the size of ordinary LCD down to $12 thousand. 40 inch SHARP LED and non LED color TV price is $11 thousand and 400, $7199.

The price of LED is "qugaohegua lamps". Lamps in the city with LED wholesale price of 6 yuan / meter, some shops can also open 8~10 yuan / M price; the same length of ordinary light with only $2.5 per meter. 12 grain LED spot price is 15 yuan / month, other halogen lamp only 5 yuan.

At present, although there are 3000 companies in the domestic LED industry, but most of the competition in the middle and lower, less R & D investment. Although the LED chip technology, higher capital requirements (i.e. upstream industry) there are dozens of participating units, but the effect of their collaboration, rather than technology output, caused each company to the upstream links on the scale, it is difficult to reduce the cost, the price of natural product LED is high.

Moreover, most of our TV manufacturers is also in the last year before starting the LED backlight production line debugging, mold development, color and other functions must have a process, to television and lighting products cost is greatly reduced, may have to wait a few years.

White LED bottleneck

In addition, the city's sales staff does not recommend that consumers buy LED lamps. What is this?

The original dealer said: do not look at the color of a lot of LED lights, blue and yellow green, but not practical. Compared to white energy-saving lamps, most of the LED lamp brightness is not enough. You put it at home, can only be used for decoration, you can not read and write. "

CBN, the reporter found that the city lamps only individual business counter to find the chandelier can change color and contain white LED light, but a 80 cm length and width of the chandelier frequently to thousands of dollars; and operators of lights and lamp cup is very few sales of white type LED.

Analysis of an unnamed source said, do white LED chip hand few enterprises, only domestic Sanan optoelectronics individual companies in Japan, there are also local white LED, but the price of imported products is very high; this kind of product development, marketing force is not big enough, it is not like that of energy-saving lamp there are a large number of financial subsidies to support the government, to encourage residents to purchase. At present, the white LED can only be used in high-power lighting such as street lights, landscape lighting and emergency lighting.

The state has also noted the prospects and difficulties of the industry. In September 22nd, the development and Reform Commission issued a "semiconductor lighting industry development advice," in 2015 to achieve the localization rate of 70% of the semiconductor chip, to give more policy support in technology, market.
