Who is the "potential killer" of ceiling lighting?
What exactly is the overflow of blue light from the ceiling?
Do LED ceiling lamp manufacturers consider it a "potential killer" to hurt people? The author conducted an investigation on this. The blue light overflow of the ceiling lamp may cause damage to the retina?
Recently, test results show that some ceiling lamps do have certain risks when they are used in abnormal conditions. Is the ceiling lamp known as the fourth-generation light source really unsafe?
The supervision of ceiling lamps urgently needs to implement compulsory national standards
Many experts suggested that the current "Photobiological Safety of Lamps and Lamp Systems" standard should be adjusted from a recommended standard to a mandatory standard, and risk monitoring should be carried out nationwide. In addition, the applicable color temperature of ceiling lamp lighting products in different places should also be specified.
Zhang Haicong, honorary chairman of the Shanghai Institute of Illumination, pointed out that the color temperature of indoor ceiling lighting products should not exceed 4000K, and ceiling lighting products with a color temperature of 6000K and above should be avoided. At present, the Shanghai Product Quality and Safety Assessment Research Center has also launched related risk monitoring projects.
How can ceiling lights be safer?
Are the ceiling lamp products on the market safe? What is Blu-ray overflow? How should special groups of people use it healthily? The reporters started to investigate.
The Shanghai Municipal Bureau of Quality and Technical Supervision has recently organized a special inspection agency to conduct risk monitoring on some commercially available ceiling lamp lighting products. It was found that among the 27 samples of ceiling lamp samples, 1 sample reached a moderate risk under abnormal conditions, that is, close to eyes. Danger to the retina when looking directly at the light source from a distance.
According to reports, the 27 types of ceiling lamp samples sampled include table lamps, spotlights, ceiling downlights, flat-panel lights and ceiling grid lights. In normal use, 14 belong to category 0 without danger and 13 belong to category 1 with low risk, all of which belong to the safe range. But if it is used in an abnormal state, that is, if the front light-transmitting diffuser is removed, one of them has reached the second category of medium danger. The current national standard limit is based on the experimental data of adults and 8-hour exposure. The cumulative long-term effects of light on the human body and certain special populations, such as infants and young children, may look directly at the light source for a long time, which may cause damage. Damage to the retina.
Does the blue light of the ceiling light become the "eye-smashing killer"?
The ceiling lamp, known as the fourth-generation light source, has achieved explosive growth in recent years, driven by industrial capital and government subsidies. However, the safety of the ceiling lamp has caused some people in the medical profession to be uneasy. Some experts worry that "the blue light of the ceiling lamp will cause damage to the retina."
Yu Anqi, deputy director of the Shanghai Lighting Product Quality Supervision and Inspection Station and chairman of the Shanghai Institute of Illumination, introduced that blue light is a light that has always existed in nature and an important part of sunlight. It must also exist in various white light sources. There is "blue light" everywhere in the environment, so it is unreasonable to equate "blue light" with "retinal damage".
