What is an intelligent eye-protecting desk lamp? How to choose?

What is an intelligent eye-protecting desk lamp? The "led eye-protecting lamp" mentioned by the shopkeeper should be called a "data storage and retrieval lamp". Its specific job is to provide lighting fixtures for practical operations such as reading articles, writing, and art painting within a certain range. The key light sources include: general incandescent lamps, fluorescent tubes, halogen tungsten lamps and leds. At present, only the lighting standard for "reading and writing ability lamps" is required in our country. The evaluation norms include the level of light intensity, uniformity of light intensity, glare control, flickering and electromagnetic wave radiation to the body, etc. A desk lamp that meets those standards can provide a pleasant natural environment for the eyes and has a certain protective effect on the eyes.

So, are all the table lamps in the sales market that claim to be eye-protecting table lamps actually designed to protect eyesight? Not necessarily. As we all mentioned earlier, the state has only set standards for "reading and writing ability lamps", but has not set actual standards for protecting eyesight. Therefore, it is impossible to ensure whether the so-called "eye-protecting desk lamps" currently on the market truly protect eyesight. According to the weekly quality analysis report, among the over 170 sampled table lamps, only less than 2% fully comply with the regulations!! So how to choose a desk lamp that causes less damage to eyesight?

1. Select the mark - CCC and CQC certifications are indispensable.

Select products that have been verified by the National Compulsory Product Quality Certification Management System (3C certification) and the China Product Quality Inspection Center (CQC). Products with CCC certification certificates have basic safety precautions. Only after this verification can the products be put on the market for sale.

2. Check the main parameters - the led color temperature, color rendering index, and light intensity are all qualified.

The true color restoration level. The higher the coloring value, the better the restoration value of the true color. According to the standard, the color rendering index should be greater than or equal to 82, and the higher the color rendering index, the better. For those with very high requirements for color rendering index, such as art painting, it is advisable to choose a desk lamp with a color rendering index of ≥ 90.

3. Anti-blue light - Select products with no risk level.

High-definition blue light has a high content and can cause damage to the cornea. Only when the high-definition blue light is ensured to be at the "harmless level" or "low damage level" are LED products suitable for general lighting fixtures. Therefore, choose a desk lamp marked "Harmless type, RG0 type".

4. No flicker - it's better if it can't be erased.

Human eyes are quite sensitive to high-frequency flashes above 50Hz. The "flicker-free" on a desk lamp means that the flicker frequency is higher than the reaction rate of the meridians in the human eyes, thereby reducing damage to the eyes. When choosing, pick an eye-protecting desk lamp of the "not easily noticed" level.
