Be careful It is the highest risk rating in the luminaire!

Recently, AQSIQ issued the national key industrial products quality supervision directory (2016 Edition), where the lighting products are as follows:

The catalogue mainly carries on the risk evaluation to the key industrial products through three aspects:

(1) the impact on the management of the performance of their duties according to law;

(2) social indicators affecting public safety;

(3) consumer indicators affecting the health and safety of people.

According to the above risk evaluation index, the paper carries on the comprehensive risk analysis to each kind of product:

Level I risk products are closely related to the consumer, the domestic market circulation, product quality and safety issues more cases, involving specific consumer groups of products;

The second level of risk products refers to the domestic market circulation, product quality and safety issues in the case of medium, low rate of supervision and inspection of products;

Class III risk product refers to the domestic market circulation is small, or is limited to a specific environment, product quality and safety problems of the case of lower product.

Eye protection lamp is the only I level risk rating in the luminaire

Eye protection lamp - as its name implies is to be able to play the role of protecting the eyes, to eliminate all aspects of the problem can damage the eyes.

Buy eye of consumers is more of the children's parents, users are children, visible eye has special use of the crowd, but we loved the next generation, because the children's eyes is still in the developmental period, bad light will cause no reversible damage to the eyes. Therefore, the supervision of the quality of eye care can not be ignored.

In an electronic business platform to enter the eye protection lamp, the search results are as many as 100 pages, most of the LED table lamp, product prices ranging from $twenty thousand to more than sixty yuan. Can be seen on the market eye protection lamp category of this category of products, the price range is also very large, will inevitably lead to quality.

The most important thing is that the state of this category of eye care products are not mandatory norms and provisions, in simple terms is exactly what kind of lamp, it can be regarded as eye protection lamp, which does not understand the standard. Unable to follow, leading to difficulties in supervision.

In view of the quality and safety risks that may exist in the eye protection lamp, the product quality supervision department of the General Administration of quality supervision organized the "eye protection" quality and safety risk monitoring. The monitoring were collected from the market packaging or instructions marked with "eye" or "no stroboscopic lamp", the results showed that 32 batches, 30 batches of samples do not meet the monitoring requirements, accounting for 93.8% of the total number of batches.

The monitoring, there are 8 batches of eye protection lamp flicker detection value exceeds the limit value of the low risk requirements; 28 batches of illumination is too low or illuminance uniformity exceeds the limit. The monitoring also collected 28 batches of ordinary table lamp for comparison monitoring, the results show that the 22 batches of samples do not meet the requirements of the monitoring, accounting for the total number of batches of 78.6%.

Monitoring shows that the so-called eye protection desk lamp is not necessarily more than ordinary lamp eye protection.

Key parameters of eye protection lamp

The color of

Earth people know that LED has blue light damage, the higher the temperature, the more blue light. National standard "architectural lighting design standards" clearly states: when using LED light source, long-term work or stay in the room and place, color temperature should not be higher than 4000K. Foreign studies have shown that the color temperature is greater than 4000K can have the security of biological.

However, the norms of the relevant norms of the lamp, the color temperature of the basic requirements, and manufacturers do not necessarily understand the lamp "building lighting design standards", thus ignoring the provisions of this specification. Led to the current market, most of the eye lamp temperature above 5000K.

The color

Color rendering index refers to the ability of the source to restore the color of the object, the color rendering index from 0-100, the higher the value, the better the color rendering ability. GB "reading and writing desk lamp performance requirements," clearly states: the color of the light source shall not be less than 82. Jiangsu quality supervision departments of the sampling results showed that 50 batches of products, the light source color pass rate of only 35%.

The illuminance uniformity

GB "reading and writing table lamp performance requirements," the control of the value of two parts.

The first part is to read and write the main lighting area, with the table lamp as the center radius of the 1/3 sector 300mm minimum illumination value should be greater than 250lx, illumination uniformity can not exceed 3;

The second part is the reading and writing auxiliary lighting area, with the table lamp as the center radius of 1/3 500mm fan sector in front of the area under the minimum illumination value should be greater than 150lx, while the illumination uniformity can not exceed 3. Otherwise there will be obvious differences in the reading and writing operation area.

In the Jiangsu Quality Supervision Department of the previous checks, the project has a pass rate of only 25%.

GB "reading and writing table lamp performance requirements," although it is specifically for the specification of the table lamp, but the scope of the application of tungsten lamp, tubular fluorescent lamp (for many years have not seen products). GB LED table lamp with no special specification. Lamp manufacturers in the design of LED table lamp, can only refer to this specification.

We try to analysis from the Oakland University in New Zealand, medicine, optometry doctor - Ms. Hu Guomin pointed out that a large number of global demonstration of what kind of light will cause adverse effects on the eye; but what kind of light is good for the eyes, what kind of light to eye, worldwide are temporarily without demonstration results. this
