Does The Full Spectrum Grow Lights Cause Harm To Humans?

The color temperature of sunlight changes with the seasons and the time of morning and evening. Therefore, the spectrum of the full spectrum lamp should change the color temperature with time and simulate the natural light environment to better conform to the natural growth law of the organism.

The full spectrum of LED light sources has been developed internationally for many years. However, the current technology is limited to the development of continuous spectrum in the visible light region to improve the color rendering index, but it is difficult to achieve continuous spectrum in the ultraviolet and infrared portions. The spectrum of each UV and IR LED lamp bead is narrow, limited to a specific band, combined into a continuous spectrum, which is very difficult and costly.
Is The Blue Light In LED Growth Lights Harmful To Humans?
The Led Plant Light source is mainly composed of a red-blue light source, which uses the most sensitive light band of the plant, and the blue wavelength uses 450-460 nm and 460-470 nm.
Blue light is a relatively high-energy light with a wavelength between 400nm and 480nm. It is widely present in computer monitors, fluorescent lamps, mobile phones, digital products, displays, LEDs, etc. The blue light in this wavelength causes the macular area in the eye. The increased amount of toxins is a serious threat to our fundus health.
Specific hazards of blue light:
1. The blue light will aggravate the disease of the macular area of the retina. With the increase of age, the lipofuscin (cell debris) left by the phagocytosis of retinal pigment epithelial cells will gradually accumulate in the retinal pigment epithelial cell layer, which will cause the retina to illuminate the chronic light. More sensitive. The toxicity of the retina increases with the shortening of the wavelength after prolonged exposure, thereby aggravating the disease in the macula.
2.Blue light can cause fundus damage after cataract surgery with age, the body's own lens will gradually yellow.
3.Blue light can have blurred vision, leading to visual fatigue, causing VDT syndrome. When the blue light is incident on the fundus, the focus does not fall on the retina but falls between the retina and the lens, which increases the distance of the chromatic aberration of the light in the eye. The distance between the focal points in the eye is the main cause of blurring of the vision, so the injection of blue light will aggravate the chromatic aberration and visual ambiguity. When the eye muscles are too tight, the blood supply to the eyes is excessively tight, and the blood supply to the eyes is strengthened. Thereby aggravating fatigue.
4.Blue light can emit higher energy between 400nm and 500nm. Light with higher energy has a higher probability of scattering when it encounters fine particles in the air, and blue light becomes the main cause of glare.
5.Blue light can inhibit melatonin secretion, disturb sleep, improve the incidence of its own major diseases. Blue light is enough to stimulate the brain, making the brain excited, affecting the law of the biological clock, it takes too long to fall asleep, wake up many times during sleep Come to wait for insomnia symptoms. People with insufficient sleep or low quality sleep have significantly reduced immune function, responsiveness, memory, and coordination, and have an increased risk of diabetes, heart disease, cancer, obesity, indigestion, constipation, depression and other diseases.
Therefore, it is recommended that when using LED plant lights, do not look directly at the eyes, it is best to wear anti-radiation glasses.

Is UV in LED Growing Lamps Harmful To Humans?
Improper use of ultraviolet light can cause damage to the cornea leading to electro-optic ophthalmia:
When UV disinfection is carried out in public places, the energy carried is relatively large. Such short-wave ultraviolet lamps and consumers can choose a safe disinfection and sterilization method in various ways. In the absence of protective measures, use UV light carefully, and if the eyes and skin of the person are exposed to ultraviolet light for more than 3 minutes, it may cause skin cancer.
In plant lights, in order to make the spectrum more full, plants can grow better. Most designers will add UV beads, which has little effect on the human body, so you can use them with confidence.

Is The Infrared Light In The Full Spectrum LED Growth Lights Harmful To The Human Body?
Customers who have an understanding of LED lights can find that there is actually no harm. In the market, there are LED RGB bulbs controlled by infrared rays. In our life, the remote control controls the TV by emitting infrared rays. The LED sensor lamps that are very popular by the public are also using the heat of the human body when the human body is approaching. Infrared detection works, so don't worry about the small amount of infrared light on the plant.
