What are the characteristics of eye protection table lamp
1. Soft light
The first characteristic of eye protection desk lamp is that the light is bright but soft. We all know that reading for a long time under too strong light can easily cause eye fatigue. As evidenced by the color temperature data of the lights, the color temperature of our common fluorescent lamps is about 5600K, which is similar to the midday sun. For reading and writing, such light is white and bright. The color temperature of light suitable for reading and writing is preferably in the range of 4000-5000K, generally in this range, the color temperature of reading light is higher, and the color temperature of writing is lower.
2. Low blue light
The so-called blue light is a kind of high-energy visible light, which can penetrate the cornea and lens to reach the macular area and accelerate the oxidation of the cells in the macular area, thereby causing damage to the retina, causing myopia, cataracts, computer syndrome, etc. Eye diseases. One of the important features of the eye protection table lamp is to filter harmful blue light, thereby reducing its damage to human eyes.
3. Large lighting range, height is higher than human eyes
The first is that the illumination range should be large. This is because if the desk lamp line is too concentrated, in a dark environment, the amount of light entering the human eye is high, the eye is easily damaged, and the light is scattered, the illumination range is also larger, and the human eye will According to the average brightness of surrounding light absorption, at this time, the absorbed light should be smaller; and the height of the light of the table lamp is higher than that of the eye. This is because, once the light source of the table lamp is lower than the human eye, the human eye will first accept darkness, Then I will be irradiated by the lamp, and my eyes will be damaged in the dark and bright.
4. No flash
No stroboscopic, which is also a basic requirement for eye protection lamps. Table lamp stroboscopic is very easy to cause vision fatigue, dizziness, eye discomfort and may even cause headaches, myopia and other consequences.
5. Anti-glare
The so-called glare is generally the phenomenon that only the lamp tube of the lamp is exposed directly or a layer of transparent plate is added, which causes the user to look up or sting his head and be injured by strong light. In fact, there is no glare-free table lamp, because no matter how soft and weak the light is, if you look directly, it will be dizzy. The so-called anti-glare of the eye protection lamp is just to protect the glare, such as adding a layer hidden.
6. Complete certificates
The formal eye protection desk lamp must have the national safety mandatory certification mark "CCC", that is, the "3C" certification. In addition, the regular eye protection lamp also includes product certification, safety certification and other certificates.
How to choose eye protection lamp
The most important thing for eye protection lamps is the characteristics of eye protection. When purchasing, other aspects should not be ignored, such as whether the material of the lamp is healthy and environmentally friendly, whether the structure of the lamp is stable, appearance and after-sales service. Let's take a closer look now.
1. The table lamp structure is safe and reasonable
Although the table lamp is small, it belongs to home appliances after all. We must first pay attention to its safety performance for all appliances. We must pay attention to whether the power cord and internal electronic wire have sufficient wire cross-sectional area and insulation thickness. Whether there is a protection device, the lamp switch is in line with national requirements, and so on. To check these, you can pull the power cord firmly to see if it is firmly connected to the desk lamp; adjust the desk lamp switch to see if the switch locks the adjustment position. Through these methods, you can roughly see the quality of the table lamp.
2. Material requirements for safety and environmental protection
Most of the current table lamp materials are made of plastic. High-quality eye protection lamps generally use non-toxic engineering plastics, but there are also some unscrupulous businesses that use potentially toxic recycled plastics for profit. To distinguish materials that are toxic, in addition to looking at the various certificates of the table lamp, the color of the table lamp is also observed. Generally, the table lamp made of non-toxic engineering plastic is lighter in color, while the recycled plastic is darker in color and has a poor appearance.
Third, pay attention to after-sales service
Don't think that the price of the lamp is not expensive, it doesn't matter after sale. Buying goods now, in addition to the product itself, service is also a very important link. When buying a desk lamp, be sure to ask for the warranty address and phone number, and understand the usual maintenance methods for the eye protection desk lamp.
