[Text|High-tech LED reporter Gan Qin] Generally, the indicator and color temperature of the luminaire are mainly expressed by the characteristics of the spectrum, that is, the spectrum is controlled by changing the combination and performance of the phosphor. To improve the spectral characteristics, we need to improve the quality of the phosphor.
"Different phosphor combinations can obtain spectra of different properties. To improve the color rendering of products, it is necessary to make a reasonable mix of green powder and red powder." Liu Ronghui, director of the Rare Earth Luminescent Materials Division, said, "take LED backlights." Say, now everyone watching TV, if you adjust the spectrum, you can make the color of the picture very beautiful."
Liu Ronghui introduced that the spectrum requirements of different application fields are different. "For example, outdoor lighting, because the human eye does not stare at the lamps, so it does not need to be particularly high. It is enough to do more than 70. You don't need red powder and green powder, you only need yellow powder."
September 26th, 14:00-17:30, September 27th, 9:30-17:30, "The 12th High-tech LED Industry Summit Forum and LED Supply Chain Brand Summit" will be held at Guangzhou Pazhou Canton Fair Held (2014 High-tech LED Exhibition held concurrently). At that time, Liu Ronghui will bring a lecture on "phosphor-based white light LED spectrum control and application program" to explore how to provide downstream customers with higher quality phosphor solutions.
In addition, in the LED phosphor industry, low-end products flood the market, and the price war is big, and the market share of low-end products in the domestic market is huge.
In response to this phenomenon, Liu Ronghui said that the current small enterprises take some bad quality products to fight the price war, which has a great interference to the market. Because of the small enterprises grabbing the market, the price reduction of yellow powder and green powder last year was very strong, and there is basically no room for this year to fall. The red powder may still have room to fall, but it will also stabilize next year.
"In the next few years, phosphors will be divided. In the end, several companies with strong R&D strength, R&D basis and relatively large scale will be formed. The remaining small enterprises will face the pressure of survival." Liu Ronghui said, "The survival of the fittest is a market law. Only when the company is at a reasonable level of competition can the industry develop healthily."
