Are plant lights harmful to humans? Which plant lights are harmful, tell you today

In the past two years, as more and more farmers have used plant lights, many people have seen on the Internet that the light emitted by plant lights is different from ordinary lights. Will those who work in the field cause some harm to the human body?

First of all, we need to understand what are harmful to humans. To sum up, there are three main threats to humans from light: one is the harm of light quality; the second is the harm of light intensity; and the third is the harm of high heat from the heat source.

1 Light quality threat

Regarding the threat of light quality, in layman's terms it refers to the threat of ultraviolet light. Ultraviolet rays may cause skin erythema for a short period of time, skin cancer may be caused for a long period of time, and direct eyesight may also cause conjunctivitis, keratitis, cataracts, etc. The sun at noon on a sunny day contains more ultraviolet rays. Therefore, the sun at noon should not be exposed to too much. Lamps and lanterns containing ultraviolet light should not be exposed for a long time. Plant lights, most of them do not have ultraviolet rays, a few or some, but the amount is not large, far lower than the ultraviolet rays in the noon sun, so don’t worry about this.

2 Threat of light intensity

This is easy to understand. You can't look directly at the sun at noon, and you will feel dizzy after a while, and there will be a risk of burning your eyes after a long time. Therefore, we generally don’t look directly at the sun. The intensity of the fill light is far less than the intensity of the sun, so it has little effect on people. We should not always look at the fill light with our eyes. It will have no effect on people. The light intensity of the laser fill light is stronger than that of the general light, so we try to avoid looking at it with our eyes

3 Harm of light and heat

Regarding the prestige of thermal light sources, it mainly refers to that some light sources emit light by converting heat energy into light energy. The light is accompanied by a large amount of heat, and the heat is too high and it is easy to burn the human body. Such light sources include incandescent lamps, tungsten halogen lamps, etc., and high-pressure sodium lamps are collectively referred to as thermal light sources.

The high-pressure sodium lamp is a typical heat source, which converts electrical energy into heat energy, and then converts heat energy into light energy to emit light. Plant lights made of heat light sources generally have relatively large heat. If the lamp is hung too close, it will burn the branches and seedlings and consume relatively high power. At present, the relatively large power consumption on the market has begun to be eliminated step by step. The laser plant light we mentioned earlier is a cold light source, which is more energy-saving. Of course, LED lights are also energy-saving. This type of light will have its own in the market in the future. Have a place

All in all, as long as the plant lamp is used scientifically, it will not harm the human body. Try not to look at any light with your eyes as it will not cause harm to your eyes.
