How to tell if the LED desk lamp has no stroboscopic?
Regarding the flicker-free LED desk lamp, I think it is still necessary for me to explain, how do we identify whether the LED desk lamp has no flicker?
The method is very simple! When we buy an LED desk lamp, we use the mobile phone camera to be close to the light source of the LED desk lamp. If the screen of the mobile phone displays a rolling stripe image, it means that the light source is stroboscopic, and the stroboscopic light source will cause frequent eye muscles. After a certain period of time, the eyes will have a feeling of sore eyes, which is visual fatigue. Each of us has basically experienced the feeling of sore eyes when reading a book. After the eyes are sore, we want to sleep.
Generally, to determine whether the LED eye protection table lamp has radiation, it can be distinguished according to the following four characteristics:
Feature 1: Eye protection performance
1. The lighting frequency is high enough, generally requiring more than 40,000 lighting times per second to ensure the continuous and stable light without stroboscopic;
2. The color rendering of the lamp is good, the light color is close to natural, and the eye protection lamp of poor quality has a low lighting frequency and poor quality of the lamp, which is difficult to protect the eyes.
Feature 2: Safety performance
It is mainly required that the power cord and the internal electronic wire have sufficient conductor cross-sectional area and insulating layer thickness. The minimum distance between the positive and negative poles of the circuit board is greater than 2.5MM, there is an overcurrent protection device, and the lamp switch meets the national requirements. Poor quality eye protection lamps do not meet the above requirements, which may lead to fire and child injury accidents.
Feature 3: Non-toxic performance
The high-quality LED eye-protection desk lamp is made of high-quality non-toxic engineering plastics, which can be formulated into a lighter natural color. Most of the inferior eye-protection lamps are produced from recycled plastics, which may be toxic and affect the health of children. Recycled materials are generally darker in color and have poorer appearance. Use oil spray and other covering methods to match the appearance color.
Feature 4: After-sale service
Brand products produced by a large company with strong standards such as Shenzhen BENWEI Lighting have more guaranteed after-sales service and customer interests can be guaranteed.
