Direct hits 3.15: LED lights in the move, are cheap to blame

At the 315 party last night, CCTV No. 1 consumer warning LED learning light, Guangdong Quality Inspection Institute personnel demonstrated LED learning lights, after instrumental testing found that high-frequency flashing learning lights are very harmful to the eyes, but the naked eye is difficult to detect. According to this researcher, the main reason for the strobe of the LED learning lamp is the internal chip. The LED learning lamp with the chip on the market has a price difference of 3 to 4 times compared with the no chip. The data shows that the illuminator of the LED lamp is a chip, which is also its core component, and the chip technology directly affects the cost of the LED lighting application. Different chips have different price differences. Among them, Japanese and American chips are more expensive, and LED chips from Taiwanese and Chinese manufacturers are lower than Japan and the United States. In 2011, the chip quickly switched from oversupply to oversupply. For example, the low-power 7.5mil 7.5mil Blu-ray chip and the high-power 45mil45mil Blu-ray chip dropped 55.9% and 55.0% respectively in 2011. The big home electric business circle search Tmall LED learning light found that the price of the product varies from 10 yuan to thousands of dollars. If a table lamp has similar appearance, different brands have different prices, and even different prices of the same brand appear. The big home electric business circle takes the Opus brand as an example. The price difference of a simple portable mobile table lamp can range from 99 to 239. For the official logo of the official flagship store, the price difference between these lamps is only different in style. There is no difference in eye quality rules. When asked if there is any anti-strobe chip, the customer service said that the Opto lamps are all LED chips, and the products are from Ruifeng and Jufei.
