Talk about LED lights

At the beginning of the 21st century, fluorescent lamps and halogen light sources dominated. Due to the global energy shortage and environmental pollution, everyone turned their attention to energy-saving and environmentally friendly semiconductor lighting, and LED came into being. Because of its low power requirements, good driving characteristics, fast response, and long service life, it has gradually replaced the traditional light source market. With the development of science and technology and the progress of the times, it is an inevitable trend for new technologies and new products to replace old products.

In the past few years of rapid development of LED, the lighting industry has also flourished. The global penetration rate of LED lighting has reached 31% in 2016 and 37% in 2017, and will continue to grow in the future... However, it is Because of the expansion of the market, too many unscrupulous merchants put product quality behind them and blindly pursue output value and profit, resulting in a large number of unscrupulous LED products flooding the market. Inferior raw materials and crude packaging technology lead to more unqualified LEDs flowing into the market. The unit price of LED products with the same appearance may vary by several times or even dozens of times. Therefore, as an expert, I hope that everyone will not be greedy for cheap and buy products with great safety hazards to go home. The damage to the eyes of this kind of inferior LED is accumulated over time, and it is irreparable when it is discovered. To buy LED products, you must buy products of big brands, and find out the chip, the brand of the driver and the parameters of the product.


The advantages of LED are high luminous efficiency, energy saving and long service life. The disadvantages are obvious light decay, high temperature, high blue light hazard of white LED, and mercury pollution in the production process and after disposal. The biggest problem now is that ordinary people cannot test the LED products they buy by themselves. Therefore, most consumers, especially ordinary people, buy back LED lamps, 80% of which are substandard products. In such a situation, eye health has become the biggest hidden danger. Most consumers don't know the seriousness of it, but they only pay attention to the luminous efficiency and energy-saving characteristics of LED.
