The spectrum of sun spectrum light (tube) is closed with sunlight’s, very soft and non-glare lighting. The eyes won’t fatigue in the sun spectrum light reading or working for a long time. After trial in school for one year, it can reduce the rate of students’ vision decline of 17%.
Sun spectrum light (tube) is also energy-saving more than 10% than ordinary energy-saving lamps, 5W sun spectrum light can compare light intensity with ordinary 9W energy-saving lamps, luminous effect of T8-36W sun spectrum light tube is greater than 90Lm / W general, up to a small number reach 102Lm / W.

Principal function and social benefit of sun spectrum light (tube)

Sun spectrum light (tube) is a new product designed for humans living colorful in sun spectrum lighting after sunset and reduce the harm for human cause by light pollution. The principal functions and social benefit are as follows in comparison with white-lighting:
(1) Relieve fatigue of eye and prevent myopia. Provide a favorable visual environment for the healthy study and growth of youths.
Modern medical research has founded that human eye is most sensitive to light wave between 530-590nm, in which the eye accepts most easily and has least fatigue, which is the inherent physiological property of human eye after several-million years’ of evolution in the sun. The spectrum characteristics of sun spectrum lamp (tube) are luminous flux of light wave between 530-590nm is close to 50% of that of the total lamp, the color is yellowish-green, the spectrum is close to that of sun's rays, and the light ray is very comfortable, which overlaps with the sensitive light wave of human eye's visual neuron mentioned above. Human eye accepts it easily with least fatigue. The one-year experiment on high school students shows that compared with white light lighting, the change of visual environment will reduce the fall of eyesight by 17%. In the investigation of ‘Bright Daily’, over 80% of high school students in China are myopic. Learning in solar spectrum light for one year may reduce the fall of eyesight by 17%. These products, which benefits our offspring and has huge market, should be promoted and developed.
In addition, personnel who work in the government, institution, marketplace, hotel, and factory, etc in the light for long time, should not be polluted by the light and should have a favorable visual environment which can reduce visual fatigue. Sun spectrum light meet the demands, help them work and live healthily, and contribute greatly to creating healthy environment and harmonious society.
(2) Expel mosquitoes
As we all know that the mosquitoes hide in the day and come out at night. It means that there is harmful component for mosquitoes in sun’s rays. The spectrum in sun spectrum light is close to that in sun’s rays, so it also has functions to expel mosquitoes. The light that cannot expel mosquitoes is not solar spectrum light.
Checked by Chinese Center for Disease Control and Prevention in Beijing, the most authorized department in out country, solar spectrum light has mosquitoes expelling rate of 86%. Due to its spectrum characteristics, sun spectrum light can expel mosquitoes.
Mosquito has different reactions to different light waves: to light wave between 530-590nm, which is most acceptable and easy to see clear by human eye with least visual fatigue, mosquito has its inherent back light biological characteristics. That is, the mosquito is afraid of this light and escapes backward as meeting the light; however, in the light below 500nm, mosquito likes this environment and has its inherent phototaxis. In this light wave, the mosquito sees objects clearly and likes this light wave. The sun spectrum light transfers the light waves that mosquito is afraid of into the lamp. Therefore, under sun spectrum light, mosquitoes feel bad. It will not fly to the sun spectrum light or fly into the room with sun spectrum light on, and will escape as meeting this light or fly slowly in the air. mosquito which flies slowly in the air will not bite human.
Seeing from the above, we will not worry that the sun spectrum light will be harmful to human body while it expels mosquitoes. Because mosquito is afraid of light wave between 530-590nm, which is good for human eye with least fatigue. Therefore, people work and mosquitoes hide in the dark in the day.
Mosquito plays largest role in transmitting ague, dengue fever and other infectious diseases. In order to decrease disease and have a good rest, people often use various anti-mosquito incenses, electric anti-mosquito incenses and mosquitocides, which are chemical and hurt human beings and pollute environment while they kill and expel mosquitoes. While people sleep in the room with anti-mosquito incenses, they will feel dry in throat and dizzy in the next morning. However, sun spectrum light makes good use of light wave, which are good for human eye but harmful to mosquito, expels mosquitoes and is good for human body.
Instead of chemical anti-mosquito incenses, sun spectrum light protects environment and is good for human body, as well as lights and saves energy. It has great social benefit and environmental protection effect used in rural districts, towns, schools, hospitals, food processing factories, garment making factories, stock farms, and aquatic plants, etc.
(3) Save energy
Sun spectrum light can save over 10% energy more than common energy saving lights. That is because the sun spectrum light selects high-purity tricolor fluorescence powder and special powder components, with high luminous efficiency.
Concretely, one 9W sun spectrum light is brighter than a 60W incandescent lamp. And it consumes 1KWH in 130 hours. Consumer can compare brightness by 5W sun spectrum light with 9W white-lighting energy saving lights sell in market.
The luminous efficiency standard for T8-36W tube of a certain lighting company famous in world is 72Lm/W, our standard is 85Lm/W. The luminous efficiencies of T8-36W sun spectrum light tubes’ are all above 90Lm/W by tested on the spot, few can reach 102Lm/W.
