We have repeatedly mentioned health lighting, “lighting should be people-oriented” has become the consensus of the industry. Manufacturers are no longer just purely concerned about light efficiency or service life, but more consideration for the human feeling of light, the impact of light on people, hoping to create artificial light closer to natural light.

Natural light is “sunlight”, 5000 years ago people mainly rely on natural light sunrise and sunset, the 19th century, along with the development of the electric power industry, the first artificial light appeared, then artificial light experienced incandescent, fluorescent lamps, to the current LED. people have been chasing the closest to the sun artificial light, with the maturity and development of LED technology, the manufacture of full-spectrum LED similar to the sun spectrum has become a hot spot in the industry in recent years. With the maturity and development of LED technology, the manufacture of full-spectrum leds similar to the solar spectrum has become an industry hot spot in recent years.

With the development of LED industry lighting, people’s requirements for the quality, comfort and other lighting overall performance of the lamps and lanterns across the board. These requirements are in fact mainly reflected in the spectrum, not just pure white light, or higher color rendering, but with a variety of light colors closer to the sunlight artificial light source. “In the future, to provide humans with higher light color quality, more comfortable and healthy light environment lighting technology is the mainstream trend of development.”

With the increasing penetration of LED lighting market, the growth of general lighting has slowed down, based on the spectrum of health lighting upgrade functional lighting has become an important direction of LED lighting upgrade.

Especially full-spectrum LED, has become the lighting industry’s current more advanced technology development trend, can better improve indoor health with light, to reduce the occurrence of myopia has a positive effect.

What is full spectrum LED?

1.Full spectrum VS full spectrum LED

Full-spectrum refers to the spectral wavelengths cover all the visible region (380nm-780nm), no obvious peaks and valleys in the spectral map, and the spectral ratio is uniform without serious disorders, while strong color rendering.

Full-spectrum LED refers to the light emitted by the lamp, its spectrum is close to the solar spectrum, especially in the visible part of the ratio of various wavelength components and the sun’s similar, the light’s color rendering index is close to the sun’s color rendering index.

Sunlight spectrum

The sunlight we see every day means the visible light part. Artificial light is also the visible part of the proportion of various wavelength components made similar to the sunlight, so that you can get a good lighting effect.

And most of our common LED spectrum is not the full spectrum, or imitation full spectrum, spectral content is the lack of certain wavelength parts, which brings the effect will be missing and affect the quality of light parameters: such as the apparent finger is not high, R9 value quite low, blue light quite more and so on.

General LED spectrum

2.Key parameters

Visible light 380nm-780nm full coverage, good spectral continuity.

Good color rendering (Ra≧95, R1~R15≧90)

3.Color rendering evaluation

Conventional white light evaluation index：Ra (100 highest), R9

Full-spectrum white light evaluation index：Ra≧95，R1~R15≧90；Rg≧90，Rf≧90

Full Spectrum Classification

The full-spectrum series is mainly divided into three categories: high-display series, double blue series and solar spectrum series.

what are the benefits of full-spectrum leds?

1.Create a natural and realistic lighting environment

We all know that an object will show its color when it is illuminated by light, but when an object is illuminated by a light source with a discontinuous and incomplete spectrum, the color will be distorted to varying degrees. We want to pursue certain special effects can not be achieved. The full-spectrum LED can create a natural and realistic lighting environment, so that the object presents a more realistic effect.

2.Regulation of human physiological rhythms

Before the emergence of artificial light sources, sunlight was the only source of light, and our ancestors lived off the sun at sunrise and sunset. Sunlight not only provides lighting and energy source for the earth, but also regulates the physiological rhythm of human beings and has an impact on human growth, psychology, and human body.

Especially modern urbanites, most of whom work in offices, rarely exposed to sunlight and cannot get the health benefits from the sun. And the meaning of the full spectrum is to reproduce the sunlight, to bring back the human physiology, psychology and human health by nature’s light

3.Eliminate the danger of blue light

Most of the traditional LED light source is the use of blue light chip excitation yellow phosphor ( produced by packaging companies ), packaging mixed to get white light. If the blue light component of this is too high, in the case of prolonged use, blue light can penetrate the lens of the human eye to reach the retina, accelerating the oxidation of the macula cells, this is often said to be the blue light hazard.

Blue light hazards have the greatest impact on primary and secondary school students , as we know, in earlier years the National LED Industry Alliance had promoted LED lamps into schools, hospitals and someother places to use, the actual effect was called off, because at that time the blue light hazards can not be eliminated effectively.Nowdays the state requires that, the school lighting should be RG0 (no hazard level), all the lamps and lanterns that do not reach this level are judged to be substandard products, which can’t be accepted.

4.Reflecting a healthy lighting environment

The light in our daily life is adjusted with the change of the sun.
If the full-spectrum lighting system can be combined with simulated sunlight at different times of the day and night to provide more like real natural light, is it better for human health?

The combination of full-spectrum lighting and control system can really bring the sunshine indoors, so that our office workers, mall employees, customers, etc. can feel the comfort brought by natural healthy lighting without leaving home.
