Keheng shares: Gaoxian LED phosphors unveiled at 2014 Gaogong LED Lighting Exhibition
[Text|High-tech LED reporter Xu Chaopeng] High-profile LED industry event--2014 Gaogong LED Lighting Exhibition will be held in Guangzhou Pazhou Canton Fair Complex on September 26-28. Jiangmen Keheng Industrial Co., Ltd. (hereinafter referred to as “Keheng Sharesâ€) will exhibit its self-developed high-color LED phosphors at the exhibition. This series of phosphors can be used in white LED packaging, and can be widely used in white light sources, display backlights, lighting and signal lights.
At present, the pursuit of high color rendering index and high luminous efficiency for LED lighting products in the industry has never stopped. But in theory, high color rendering index and high light efficiency are a pair of contradictions, they show an inverse relationship, and how to find the balance between them is precisely the key to the current breakthrough in indoor lighting technology.
"As we all know, if the color rendering index of white LEDs is to be improved, in addition to using high-index chips, it is necessary to work on phosphors." Chen Tao, general manager of Keheng's LED business unit, said in an interview.
It is reported that the current white LED mainly adopts the production process of YAG yellow phosphor coated by blue chip developed by Nichia Chemical Co., Ltd., and in a certain sense also follows the principle of fluorescent light. "But this kind of production process is lacking in the color rendering index due to the lack of red and green light components. In order to make up for this defect, upgrading the phosphor technology has become the main direction of the current industry." Chen Tao told reporters .
The two high-color LED phosphors newly developed by Keheng Co., including a yellow-green powder of model LAG-533 and a red powder of model R-625BH, all have high light conversion rate. Stable chemical performance, safety and environmental protection. To a certain extent, they can all make up for the shortcomings of the current traditional phosphors in terms of color rendering index.
According to the reporter, this LAG-533 yellow-green powder of Keheng is based on the traditional YAG yellow powder series, and developed a high color rendering index product for the current market demand, which can not only make up for the silicate green powder. The instability is also able to provide higher indexing. So far, the yellow green powder has started mass sales.
"In the field of LED lighting, Keheng shares are optimistic about the future development of LED phosphors in the field of indoor lighting." Chen Tao also said that in the future LED lighting products will pay more attention to the quality of LED phosphors, Keheng shares will continue to focus on Improve the quality of products, and return more LED industry customers with more high-quality products.
