The eye protection table lamp market is mixed, and many inferior products are flooded with it, which causes great interference to consumers' choices. So what are the characteristics of an inferior table lamp, and how should consumers distinguish and choose the right eye-protecting table lamp?
1. Typical characteristics of inferior table lamps
1. Vague publicity
The normal publicity of the eye-care table lamp will indicate the parameters of the relevant technical indicators on the publicity details page, such as illumination, illumination uniformity, and color temperature, and then focus on the highlights of their own products. Inferior table lamps will take the form of blurring and exaggerating publicity. For example, some have been emphasizing the high brightness of their own products, but they don't say what the measured illuminance is, whether it is in line with the national AA illumination. This kind of propaganda method of exaggerating how good their products are and deliberately blurring the key index parameters on the other hand is a typical feature of inferior table lamp products. Therefore, consumers should be more careful when encountering such products, and do not fall into the propaganda routines of unscrupulous merchants.
2. The price is extremely low and feature-rich
Although the technical threshold of the eye-protecting table lamp is not high, it still requires a certain cost in order to meet the various technical indicators stipulated in the national standards. In particular, if you want to add some unique functions, such as automatic induction light on/off, intelligent APP control, automatic dimming, timing reminders, etc., it will raise the cost of products. Therefore, consumers must be vigilant when dealing with products that claim to have rich functions but are very inexpensive, because there is a high probability that such products are inferior.
2. How to choose a good eye-protection table lamp?
1. Look at the technical parameters
The specific parameters of a qualified eye-protection desk lamp should meet the national standards for illumination, illumination uniformity, color temperature, blue light hazard level, strobe, color rendering and other indicators. Specifically, it meets the standard of "Performance Requirements for Desk Lamps for Reading and Writing Operations". The national standards have made requirements for the specific parameters of the above technical indicators. For example, the blue light hazard is required to reach zero blue light hazard, i.e., RG0; 4000K color temperature should be used for reading and writing at night; The general color rendering index Ra>80, the special color rendering index R9>0 and so on. Of course, in specific practice, the above index parameters are still low, such as color rendering, in practice, consumers can choose eye protection table lamps according to Ra>90, R9>90.
All in all, as ordinary consumers, we should check the parameters of the product when buying an eye-friendly table lamp, if a product is not marked with key parameters, then we should be careful not to buy inferior products.
2. Look at the way of excitation
Traditional LED lighting fixtures use blue light excitation technology. This technology inevitably produces harmful short-wave blue light, which is also the origin of the blue light hazards of LED lighting fixtures. Although manufacturers will filter out harmful blue light through technical means, so that the blue light hazard reaches the level of RGO. However, with the increase of the service life of the product and the gradual aging of the parts, the blue light protection ability of the product will inevitably decrease.
In this regard, some table lamp products now adopt purple light excitation technology, which completely avoids the appearance of high-energy harmful blue light, and the blue light protection effect is better and more thorough. Therefore, if a product adopts violet excitation technology, it means that the technical level of this product is relatively high and the safety is better.
3. Take care of the eye effect
In order to achieve the real eye protection function, the current mainstream practice is to add red light and eye benefit technology. This technology can emit beneficial long-wave red light, speed up blood flow to eye muscles, promote metabolic repair of retinal cells in the fundus, relieve eye fatigue, and play a real role in eye protection. Of course, there are not many products that use this technology at present, so consumers may wish to take a look at the few recommended by the author if they want to buy this kind of product.
Dr. Edward: Angel Light 2
Angel Light 2 adopts the self-developed NIR red light eye protection technology, which applies low-power NIR red light in a specific band to increase the mitochondrial metabolism of retinal cells, actively repair fundus cells, delay eye fatigue in adolescents, and improve visual acuity. At the same time, this table lamp also adds a scene light switching function, leisure, learning, and creation of the three major scenes can be switched freely, so that consumers can enjoy the most suitable light in each scene.
Comic Book Rain K1
The technical parameters of Manshuyu K1 are better than the national standard, such as Ra=98, R9=92, and the minimum horizontal illumination = 634lx, which is greater than the national standard of 500lx; Illumination uniformity = 1.9, much less than 3; The constant color temperature of 4000K fully meets the lighting requirements of reading and writing activities at night. What's more noteworthy is that the K1 not only uses violet excitation technology to better eliminate the harm of blue light, but also uses red light technology to provide users with real eye protection.
Panasonic Zhizhun 3G
As an international brand, the quality of Zhizhun 3G is also guaranteed, and its technical index parameters are in line with national standards, and AAAAA standards are adopted, and all kinds of technical parameters are very good.
