We know that we cannot be exposed to the sun for a long time, for three main reasons.
First, the long-wave ultraviolet (UVA area) in ultraviolet rays can not only penetrate windows, umbrellas, but also the dermis layer, making the skin tanned, resulting in collagen and lipid damage, causing skin aging or skin cancer. Medium wave ultraviolet (UVB area), which can reach the dermis layer, causing bare skin tanning, causing peeling and erythema.
Second, the noon sun can not be seen directly, otherwise the light is too strong and light will make people dizzy, heavy will cause eye fatigue, and over time cause vision decline.
Third, in the sunlight accompanied by a lot of heat, the heat is too high, easy to dehydrate, especially in the hot summer.
So, since the principle of plant growth light filling light is made according to the photosynthesis of plants to sunlight, is it harmful to the human body in the process of filling light for plants?
Whether plant grow lights are harmful to people, the key is to see what kind of lamps you buy. That is to say, if you buy a plant grow light spectrum ratio is unreasonable, such as containing UVA, UVB ultraviolet rays, providing solar radiation heat of 1000nm ~ 3000nm infrared light, strong light dazzling and other products, then in the process of use must be harmful to the human body.
Therefore, in the purchase process, we must choose plant grow lights produced by regular professional manufacturers, such as LED lamp manufacturers with a history of 18 years – Shenzhen LEDZEAL.
LED grow lights produced by LEDZEAL do not contain UVA and UVB ultraviolet rays that are harmful to the human body to avoid skin damage; Cold light source, does not contain infrared rays ≥ 1000nm, avoiding a large amount of heat accumulation; The light intensity takes into account the comfort of the human eye and the experience is good.
In addition, based on the specific needs of different plants for light quality (spectrum), light intensity and photoperiod, Shenzhen LEDZEAL’s LED grow lights provide reasonable and accurate spectral ratio to meet the light needs of different growth stages such as plant growth, flowering and fruiting; Ceramic heat dissipation technology, fast heat dissipation, good insulation and long life; Professional secondary light distribution, uniform light, plants do not grow.
