1. Are full-spectrum ceiling lights an IQ tax? What is the difference between full spectrum ceiling lights and ordinary ceiling lights? First of all, we must understand that buying a lamp is not about buying efficacy. If you want to use full-spectrum ceiling lamps to restore vision or treat eye diseases such as cataracts, these ideas are a bit outrageous. So what exactly does full spectrum do? In fact, the damaging effect of the light source depends on four parameters: spectrum, light intensity, daily illumination time and cumulative exposure time. The exposure time depends more on personal habits and activity needs, but the spectrum and brightness are closely related to the type of light source.
2, The ratio of red, green and blue is close to that of the full spectrum of sunlight. The most important thing we need to analyze is its visible light region, and the most important colors in the visible light region are red, green and blue. Red light: Research on the pathogenesis of myopia has found that the use of red light irradiation can improve the blood circulation of the fundus and inhibit the abnormal growth of the eye axis, so that the eyes will not feel tired after long-term use. Green light: Appropriate green light value can relax the eye muscles. The principle is the same as when we look at distant green plants to relax our eyes after looking at mobile phones or computers for a while. Blue light: The wavelength band of blue light is between 400-500nm. 460-500nm is beneficial blue light, which can promote sleep and adjust rhythm. However, remember that the peak value of blue light should not be too high, otherwise it will damage retinal cells and cause eye diseases.
The short-wave green light and long-wave red light parts of ordinary ceiling light sources are obviously missing, and the peak value of blue light is ridiculously high. The wavelength composition and proportion of the full-spectrum light source are very similar to that of sunlight, almost all the light in each band is completed, and the lines are also very smooth, reducing the problem of visual fatigue. BENWEI's full-spectrum ambient black ceiling lamp does this very well. The blue light peak is very gentle and basically matches the value of the solar spectrum. It reaches the RG0 immunity level for blue light damage and reduces the risk of myopia in the family. It also adds red and green light areas that are beneficial to the human body, effectively relieving visual fatigue and greatly improving the comfort of the light environment.
3. Ra CRI is closer to 100. As we all know, an object will show its color when illuminated by light. However, if it is illuminated by light with discontinuous and incomplete spectrum, the original color of the object will be distorted to varying degrees. Everyone has tried to buy clothes in a physical store. Many times, the colors of the clothes you try on in the store are different from those outside. In fact, this is due to the different color rendering values of the lights. The same applies to home scenes. Under the illumination of high color rendering index lamps, the true colors can be restored to a greater extent. Under sunlight, the color displayed by an object is 100%. The closer the color rendering index of the light is to 100, the higher the degree of restoration of the true color of the object and the better presentation of various colors.
At present, the CRI of most LED lamps is ≥80. Generally, a ceiling lamp with a CRI of 90 is already superior, and the price is quite expensive, but the full spectrum can basically be controlled above 92.
Especially for families with children, the eyes are in a developmental stage, which is a critical period for distinguishing colors. If you buy a ceiling lamp with a low color rendering index, it will gradually weaken the child's ability to distinguish colors. In severe cases, it will lead to color weakness and color blindness, which is not conducive to the healthy growth of the child. Therefore, when choosing lamps, especially lamps for children, it is recommended to give priority to full-spectrum ceiling lamps with high color rendering index. Children can also experience real colors while reading books, reading picture books, and raising plants indoors.
4. There is no video flicker, the light is softer, and the stroboscopic visualization is even. Every time the stroboscopic flicker occurs, our eyelid muscles will beat. The muscles are in a state of tension for a long time, and the eyes are easily fatigued. Over time, it will lead to vision loss. Dizziness and nausea may also occur.
5. More refined brightness and color temperature adjustment. What kind of light is the most eye-friendly? Undoubtedly the closest light to the solar spectrum. So what kind of brightness and color temperature is the most comfortable? It's very simple, look at the changes in light in nature throughout the day. When the sun first comes out, it appears orange-red, and the color temperature is the lowest at this time, between 2200-2700K. At noon, it appears yellow-white or pure white, with the highest color temperature, about 5700K, and then slowly decreases. Therefore, the larger the color temperature adjustment range of the ceiling lamp, the more it can adapt to the lighting requirements of different scenes, and the more comfortable it will be. However, the temperature adjustment range of ordinary ceiling lamps is generally between 3000-5000K, which makes it difficult to achieve the bright and serious lighting effect at noon. Full-spectrum ceiling lamps have a wider temperature adjustment range, and can generally be adjusted freely from 2700K to 5700K. Some full-spectrum ceiling lamps also have different built-in modes according to different scenarios, such as office study, family meetings, parent-child activities, etc., which can be easily set up with one click, which is very convenient.
All in all, when buying a lamp, it depends on whether it is useful or not. High-quality lamps are more comfortable to use and can better reduce the burden on the eyes. Generally speaking, as long as the lighting mode is chosen correctly, the lamp you buy depends entirely on your budget. Although full-spectrum ceiling lamps are more expensive, the lighting mode is almost impossible to make mistakes, and novices will not be fooled. It saves time and saves time. Save effort.
