[High-tech LED reporter / Zhu Chunwei] The annual "Double 11 Shopping Carnival" not only makes the major e-commerce platforms more popular, LED lighting also avoids the smashing of traditional lighting sales channels. However, as the emerging power of the LED lighting industry in the e-commerce field, the price confusion and quality are uneven, and the shortcomings with obvious e-commerce characteristics are also exposed.
In the seventh round of CLEAR inspection plan, the organizer Gaogong LED purchased 30 different manufacturers of LED spotlights from Tmall, Taobao, etc., and many important parameters were unsatisfactory. In particular, the display requirements for red in the color rendering index, of which 16.7% of the samples have negative R9 values, and the lowest is JFHD-3W-3016, which is -33. The purchase price of these samples is relatively low, mostly around a dozen yuan.
What is R9, and what effect does this low parameter have on LED lighting? Is the technology not meeting the requirements or is it because of other reasons that R9 can't do it? With these questions, the reporter consulted some well-known testing institutions and visited LED manufacturing companies.
The so-called R9 is the display requirement for red in the color rendering index of the lamp. The larger the value, the higher the redness of red. Li Shiji, Marketing Manager of Guangzhou Saixi Photoelectric Standard Testing Institute, explained to reporters that the higher the R9 is, the better the effect is brighter in fruits and flowers. In particular, the R9 value of the LED spotlight, which is the main force of Shangchao Lighting, cannot be negative.
How to increase the R9 value of the luminaire plays a important role in the nitride red powder.
"Improving the R9 has no obstacles in technology. There are two main methods at present: white light beads plus red powder or red light beads. The common practice is to add red powder, but the price of red powder is relatively much higher." Chairman of the company, Zhu Fan, said that in the environment of the increasingly low price of packaged devices, companies want to reduce the cost pressure as much as possible, and reducing the use of red powder has become the unspoken rule of the industry.
