According to a recent report by the British "Daily Mail", a recent study by Spain shows that LED energy-saving lamps may cause damage to people's vision. Research experts believe that lamps such as desk lamps should not use LED bulbs as close as possible. When the news came out, there were different opinions. Some netizens immediately said that they will no longer use LED desk lamps, but many people have expressed objection, saying that this statement has the suspicion of "indiscriminately killing LED sticks." The report can only target "three inferior LEDs." LED lights that are generally optimistic in the industry, is there a hidden danger of damage to the retina? Come listen to the analysis of ophthalmologists and lighting source experts.
View: Long-term use may damage the retina LED <br> <br> According to the British "Daily Mail" reported that Spain Complutense University of Madrid (Complutense University in Madrid), Dr. Celia Ka Sangsi · · Ramones ( Celia Sánchez-Ramos's research shows that because the light emitted by LED lamps is a short-wave high-energy light source, it is blue and violet in the visible light spectrum. Exposure to such light for a long time may cause damage to people's retina.
Dr. Kasans Ramons also pointed out that the light radiation emitted by energy-saving lamps can cause serious damage to human retinal pigment epithelial cells. To this end, he suggested that LED lamps should be used as close as possible to lamps such as desk lamps. Try not to look directly at the light source with your eyes, and pay attention to the time of use. Close your eyes every 20-30 minutes and rest for a while.
Ophthalmologist: Blu-ray and more brightness, may hurt the eyes <br> <br> Zhongshan Ophthalmic Center senior optometrists, optometry experts said Lu Jinhua, different wavelengths of light, penetration is not the same. The light that is harmful to the eyes is mainly high-energy short-wave light, such as blue light and purple light. The most comfortable one is the green light of the medium wave. The blue light has strong penetrating power, and the energy in the spectrum is relatively high. It can penetrate the cornea and the lens and reach the retina. Once the retina is damaged, it will cause irreversible damage. Therefore, the biggest damage to the human eye is the long-wave, relatively high-energy blue-violet light.
The LED lamp emits light, has a single color, high energy, high color temperature, and contains blue light. "For a cell, if it accepts a high-energy photon, it may cause some hardness to its nucleic acids and proteins, causing the entire cell to be fatally threatened."
"I think that the research of the expert in Spain mentioned that the damage of LED to the eyes is mainly directed to the blue component in it. After a long time, it may cause irreparable damage to the retina. This is reasonable. â€
Lu Jinhua believes that LED lighting may be harmful in two aspects. The first is that the blue light content is more, which damages the retina; the second is that the brightness is too large, which will stimulate the eye to constantly adjust and cause eye fatigue.
In addition, LEDs may also form glare. Glare means that the local brightness is too high and is not proportional to the surrounding environment, causing the retina to produce bright and dark areas, resulting in dramatic changes in the pupil. Glare can cause eye irritation and other problems. If the glare phenomenon and the stimulating stimulus are relatively large, it will have a negative impact on the human eyesight. If it is in the blue light hazard and glare phenomenon for a long time, it will add importance to fatigue and damage the optic nerve, especially the visual acuity of young people whose vision has not stabilized for a while.
Lu Jinhua also stressed that on the other hand, LED lamps are the most promising source of energy conservation and environmental protection. "We cannot deny it because of the current state of the art and some inferior products. We must also acknowledge There are some relatively good quality LEDs, and there will be continuous process improvements in the future, such as making the color temperature more gentle, reducing the blue light content, and the brightness design is more reasonable."
Lighting source experts <br> <br> a clarification: Blu-ray Blu-ray does not mean harm Design Director <br> <br> Guangzhou Cypress Lighting Engineering Co., Ltd., senior lighting designer Xu Qinghui told reporters, "blue light hazard" is just a noun It is not "Blu-ray = Hazard". Just like "traffic accidents", there is a possibility of accidents when there is traffic. Reasonable use, quantitative evaluation, qualified LED can be used with confidence.

This series is an effect maker on the stage, including laser lights with multi-segment shape changes, electrodeless lights with sudden changes in color angles, matrix lights that can display fixed patterns or letters, etc., both in color and light shape. outstanding effect. The laser light has been edited to show a 3D stereoscopic effect. With the delay effect in the venue, the laser light with strong penetrating power can show a more beautiful effect. If you want the stage to be more cool, the effect light series is also an essential option.
