Light health will redefine LED full spectrum

With the development of society, the importance of light sources has become more and more prominent. More and more classroom lighting fixtures and study lamps use LED light sources that are gradually becoming full-spectrum light sources. So, what is an LED full spectrum light source? Where is the future development space for full spectrum?

 

With the development of society, the importance of light sources has become more and more prominent. More and more classroom lighting fixtures and study lamps use LED light sources that are gradually becoming full-spectrum light sources. So, what is an LED full spectrum light source? Where is the future development space for full spectrum?

 

Full spectrum, as the name suggests, has all the spectral components. The reference object of LED full spectrum light source is the sunlight spectrum. As we all know, sunlight is the healthiest light. Human beings have evolved under sunlight for millions of years and have already adapted to the sunlight environment. The meaning of full spectrum is to reproduce sunlight and bring back to us the benefits of natural light on human physiology, psychology, and human body.

The sunlight spectrum includes the visible light spectrum part and the invisible light spectrum part. The invisible light spectrum is mainly ultraviolet and infrared rays. Currently, the full spectrum described in the field of LED lighting mainly refers to the full spectrum of visible light, which means that the proportion of various wavelength components in the visible light part is similar to that of sunlight, and the color rendering index of light is close to that of sunlight.

 

In fact, the earliest electric light source used by humans, that is, the incandescent light source, has a continuous spectrum that covers the visible light spectrum. It has a high color rendering index and can be said to be the earliest full-spectrum light source. However, due to the low efficiency and short life of incandescent lights, they were later replaced by better LED light sources.

 

Early LED light sources also had problems with low luminous efficiency and insufficient spectral components, but with the development of technology, these problems have been solved. Nowadays, from a technical point of view, LED light sources can achieve full spectrum very well, and the color rendering index is also very high. However, due to price and application, full-spectrum LED light sources have not yet been widely used. Nowadays, driven by the comprehensive prevention and control of myopia in children and adolescents across the country, it is believed that full-spectrum LED light sources will receive more attention, and the pace of their promotion and application will be accelerated accordingly.

 

However, just the "full spectrum" of visible light cannot completely solve the problem of myopia in children and adolescents. According to a joint study by the Sun Yat-sen University Eye Center, Foshan Second People's Hospital and Guangdong Cosio Lighting Co., Ltd., the infrared spectrum component of invisible light has a very important impact on myopia in children and adolescents. Project research shows that the fullness of the red light spectrum directly affects the human body's myopia, immunity, and skin health. The importance of the red light spectrum can be seen from this.

For example, the infrared spectrum is an important part of the invisible light spectrum. The infrared spectrum is divided into three regions: the near-infrared region has a wavelength of 0.8-1.5μm, the mid-infrared region has a wavelength of 1.5-4μm, and the far-infrared region has a wavelength of 4-1000μm.Among them, the wavelength band of 4-14μm can be effectively absorbed by living organisms and is called "life ray". Infrared rays play a very important role in human health. It can improve human immunity, promote tissue regeneration of biological cells, and can treat a variety of diseases.

 

In addition to infrared spectrum, ultraviolet spectrum also plays a very important role in human health, such as synthesizing vitamin D and promoting strong bones. Therefore, the future development direction of LED full spectrum must be to further align with sunlight and include invisible light spectrum components. At that time, LED full spectrum is no longer a category of lighting, but a category of light health, which can be widely used in light health care and light medical treatment.

 

Light health will redefine LED full spectrum, because the reference of the full spectrum itself is the sunlight spectrum, and the core theory of light health is "sunlight is the healthiest light". Its three core technologies are light code and light formula. and light control. In the light health system, whether it is visible light or invisible light, each spectral component has its own unique role. The important work of light health is to configure and control these different spectral components for human health.

 

Although LED full spectrum is an emerging market, it has full potential for future development, and light health is a trillion-dollar industry. We believe that only "LED full spectrum" that fully and flexibly configures the visible light spectrum, infrared spectrum and ultraviolet spectrum can be truly full spectrum, and it is exactly the light health we strongly advocate!
