[Text / high-tech LED reporter Zhu Chunwei] "To reduce the light hazard of LED, the first is to improve the color rendering index, especially to improve R9 (red restore authenticity) can make the entire spectrum significantly changed. But R9 is difficult to upgrade, but it is difficult, Need to pay more attention in the packaging process." Dr. Wu, who is responsible for the technical aspects of Fujian Desheng Optoelectronics, told the reporter that because there is no relevant mandatory standard, the gap in the R9 value gap under the current technical conditions is very common.
It is understood that LED lighting products, especially indoor lighting, generally require R9>0, while some better products R9 values ​​are generally between 20-60. R9 can reach 60, the display index is above 90, so the requirements for all aspects of the lamp are also strict.
However, the actual situation is not optimistic. The data of 40 3W LED bulb manufacturers from the market's fifth round CLEAR inspection project showed that there are only 17 products with R9>0, the ratio is only 42.5%; The highest R9 is the 3W bulb of 3 billion light, which is 38.4, which is 86.9. The lowest is Orkney, the R9 is negative 69.2, and the index is only 60.

The lamps of some brand enterprises can basically achieve the standard on the R9. For example, the R9 values ​​of the products of Op, Philips and Yiguang are all above 0, while some lamps with low price competition generally have the R9 value below 0. , represented by the rectangular, snow Wright and so on.
"Of course, some companies are not willing to add cost, in order to ensure the light effect and sacrifice the index, which leads to the general low R9 value." Yin Hui, director of the market for Ningbo Shengpu Optoelectronics, said, "To ensure the lamp beads When R9 is above 0, it is necessary to be stricter on the phosphor ratio, especially the red powder, and the corresponding lamp bead cost price will be higher."
The High-Tech LED Industry Research Institute (GLII) reminds consumers to pay more attention when purchasing lamps. Some lamps that are too small can be lit, but long-term use may cause harm to the human body. Can't just be cheap, or choose more guaranteed brand products.
