How To Apply LED Lighting Healthfully

LED lighting source has many advantages over traditional light source. It is the development direction of lighting source. We have entered the era of LED lighting. However, if we do not pay attention to the influence of blue light on human eyes in LED lighting, the harm of blue light will exceed that of metal halide lamp and fluorescent lamp, and high color temperature LED light source will lead to it. "Blu-ray hazard" is more serious, "Blu-ray hazard" is generated in the lighting environment without awareness, only in the scientific use of methods to ensure security; the most important thing is that light producers need to have these basic knowledge.

"Blu-ray hazard" is a public health problem, product information should include these content, LED lighting source blue radiation detection is the only way to judge the safety of products; it needs to be noted that LED lighting source does not necessarily mean that there is a "blue light hazard", blue radiation and radiation time is to distinguish "blue light hazard" The premise.

The higher the power of LED lighting products, the higher the hazard of blue light. Usually, more than 20W LED light sources in use pay attention to the installation height, the higher the installation height, the less the hazard of blue light.

The blue radiation of LED illumination light source decreases with the decrease of color temperature. The low power LED light source with color temperature between 3500 K and 2800 K basically conforms to the national standard. The white light with color temperature above 6500 K has the influence of blue radiation.

With the increase of color rendering, the blue radiation decreases. The increase of color rendering means that phosphors need to absorb more blue radiation energy and excite a broader spectrum. Therefore, the LED lighting source with high color rendering index is relatively safe.

1. For commercial lighting, it is recommended to use LED white light with color temperature below 6000K, the maximum should not exceed 6500K.

2. For office lighting, it is recommended to use color temperature between 5000K and 3200K.

3. For home lighting, try to use a single lamp power lower than 8W LED lamp, color temperature below 3500 K;

4. For lighting LED, try to use high color rendering products.

5. For reading table lamp, it is better to use LED light source with high color rendering and color temperature below 3200 K and power below 6W.
