The human pursuit never stops, and the demand for health is reflected in all aspects. Just as eating isn’t just about hunger, and our need for light not only about lighting but also require healthy lighting environment, and this is also a new trend of the future.

 

The biggest problem in ordinary LED lighting is that the light is dominant in the blue wavelength (wave length: 380-450um). That is it contains a high amount of blue light. Which is harmful for humen health.

 

Key value concept of Healthy light is “Natural light, true color”. We are in the process of questioning ourselves what is good light and how to define good light.We started to focus on Healthy Light in 2020, and now we have found a right direction: comparing industrial light with humanistic light; natural light is better than artificial light.

 

For thousands of years, our ancestors lived a life of work from dawn to dusk. It is only in the last 200 years thatindustrial artificial light has entered our life.

The sun has profound effects on the human body. Our visual senses, circadian rhythms, and mental mood are better when exposed to light that is more likely to the sun, that’s why when it comes to healthy lighting, full spectrum is a very significant point.

For healthy lighting: First of all, there are three obvious differences between full-spectrum LEDs and ordinary LEDs in the spectrum.

The first is that the blue light of ordinary LED is too high, far above the solar spectrum. We know that short-wavelength blue light (wave length: 380-450um) can reach the macular area under human eyes and definitely causing damage. Long-term exposure to ordinary LED lighting with high blue light can affect the human eye and even lead to pathological changes. In addition, our body’s secretion of melatonin has a profound impact on our sleep. The more melatonin we produce, the sleepier we feel. If too much exposure to blue light before bed, it will inhibit the secretion of melatonin, cause insomnia, affecting sleep quality of human being.

Secondly, there is a “trough” in the spectrum of ordinary LED near 480 nm between blue and green light, with poor spectral continuity.

This results in the deficiency of ordinary LED in the rendering of this part of color. Under such light environment for a long time, our visual perception will generate inertia, which will affect our judgment of color.

The full-spectrum LEDs cuts down the blue light in the spectrum and makes up for the missing light component in the 480 nm band as much as possible. The spectrum is smoother and more continuous, closer to the solar spectrum, healthier and more consistent with people’s cognitive habits of color.

It should be added that the full spectrum of LED should be the full spectrum of visible light, excluding the part of infrared and ultraviolet. Therefore, full spectrum technology does not mean to completely restore the sun’s rays. As part of the infrared and ultraviolet rays are harmful to human body.

Third, full spectrum LED is high CRI LED with, high saturation and high color fidelity, which can present real colors. For example, the full spectral COB LEDs is always more  than Ra>98, Rf>95 and Rg 102, which is very close to natural sunlight and approximates the real color of the irradiated objects.

We use this technology in our ceiling lights and downlights, we are trying our best to supply the world with Healthy Lighting.
