What are the effects of different light sources on health?

time: 2018-06-10
The impact of lighting on health is not only the spectral components of the light source, but also the electromagnetic radiation of the driving part, the noise, the glare of the light source or thelamp, the strobe of the light source, the safety of the lamp, and so on. Wavelengths, does not mean that there must be a negative impact on health, in fact, these light sources have been with people’s work and life for many years. The basic components of all the light source is red, green and blue light, the blue ray’s effect on human eye have been there all the time and with be with human’s life. We just need to learn how otavoice the blue ray and scientific use, Blu-ray hazard can be controlled within the safety value. Based on the full spectrum of the professional-grade artificial light source, we will provide you with a scientific knowledge from a professional perspective. We hope to help you understand thehealth effects of the lighting of the artificial light source. 1.Incandescent bulb Full spectrum as shown below, incandescent is widely used in a variety of lighting applications. incandescent light spectrum The effects on health: 1. UV UV-A content is very small, you dont have to consider the impact of UV on health; 2. UV UV-B: no. 3. the blue light is small, the irritation to eye is small,the blue light of incandescent light source is the most secure among all indoor lightings. 4. near infrared content is high, long-term lighting will lead to skin dry, easy to cause wrinkles, light source surface temperature is high and easy to burn. In summary, high-intensity infra-red long-term direct exposure to the eyes can also cause cataracts. As incandescent light luminous efficiency is very low, it is out of date. From the point of view on health, incandescent effect is very small. 2. LED lights Full spectrum diagram are shown below, LED lights are widely used in a variety of lighting environments and increase more and more. led spectrum 1. UV UV-A content is very small 2. UV UV-B: no 3. blue light content is high, may have retinal damage, color temperature below 3500K blue radiation is relatively safe 4. almost no infrared content, do not need to consider its impact LED white light is produced by the blue chip inside led and yellow phosphor covered on the chip. LED lighting source has many advantages over the traditional light source, which is the direction of development. we have begun to enter the LED lighting era, but if you do not attach importance to blue-ray to human eye, “Blu-ray hazards” will be higher than metal halide lamp and fluorescent light, high CCT LED light source will lead to “Blu-ray hazards” more serious, you can not feel the”Blu-ray hazards” in lighting environment, only in the scientific use of lighting can protect your health against blue rey. the most important is that The light source producers need to have these basic knowledge.
