We all know that LED grow lights supplement light for vegetables and fruits in greenhouses. LED grow lights are made according to the principle of the sun, which can effectively help grows grow and produce results. But it also affects the human body. I wonder how much you know?
In fact, there are three main threats to our human body from LED grow lights:
1. Ultraviolet radiation, short ultraviolet radiation may cause skin erythema, long time can cause skin cancer, and eyes can also cause conjunctivitis, keratitis, cataracts, etc. The sun at noon on a sunny day contains more ultraviolet rays, so the sun at noon should not be exposed for too much time. Lamps and lanterns containing ultraviolet light should not be exposed for a long time. Most of the LED grow lights do not contain ultraviolet rays, and a few still have them, which are much lower than the ultraviolet rays under the noon sun.
2. Light intensity, we all know that too strong light will harm our eyes, I believe this is people’s life experience. You can't look directly at the noon sun. The mild ones can cause dizziness, and the severe ones can cause eye burns. The high-intensity laser ultraviolet is stronger than the noon sunlight, and it is impossible to look directly at it. Looking directly at the laser can cause macular burns, and even more disease can lead to loss of vision. This kind of physical damage often cannot be repaired.
3. The blue light of LED grow lights is the same as other electronic products, which is harmful to human eyes. This aspect needs to be paid attention to, so you need to wear anti-blue goggles to protect your eyes.
The harm of blue light:
1. Blue light will aggravate the disease in the macular area of the retina;
2. Blue light can cause damage to the fundus after cataract surgery;
3. Blue light can cause blurred vision and cause visual fatigue;
4. Blue light can cause glare;
5. Blue light can inhibit the secretion of melatonin and disturb sleep.
Although LED grow lights have an impact on the human body, of course they can be avoided as long as they pay attention to protection. After all, LED grows can bring a better growth environment for grows and bring good benefits to growers.
In addition to paying attention to the impact of LED grow lights on the human body, we should also pay attention to the following aspects:
cooling problem
If you are using it in large space areas such as greenhouses and industrial parks, the heat dissipation of LED grow lights is naturally not a problem. However, the home space is limited. If you do not pay attention to the air circulation, the temperature of the space will continue to rise. The heat dissipation of the LED grow light will be a problem, which will affect the performance and service life. Therefore, you can choose air conditioning, fan heat dissipation or keep the air circulating, etc. Method.
Fill light distance
LED grow lights will generate a certain amount of heat. If they get too close, they will burn the grows and cause some damage to the grows. If the distance between the LED grow light and the grow is too far, it will greatly reduce the light utilization rate, thereby weakening the light supplement effect. If the heat of LED grow lights is less than other grow lights, but there will be a certain amount of heat. If the distance is too far, it will also affect the effect of fill light.
Fill light time
If the weather is fine, the grows can fill up the light for 2-3 hours in the morning and evening when the light is weak. If it is cloudy, rainy or hazy, grows can fill up the light all day. There is a time limit for grows to supplement light. grows have 14 hours of supplementary light a day, which is a very suitable time. They also need to rest at night and have time to breathe.
Lighting problem
The home space is limited, the installation is too inconvenient or the installation location is unreasonable. Will affect the growth of grows, because the installation angle is not correct or unreasonable, so that the light distribution of LED grow lights is uneven, then the grow will grow poorly if the light received is different. To solve this situation, it is best to choose a foldable or sliding LED grow light, which can well adapt to the size of the space and is easy to install.
Don't be greedy for cheap
LED grow lights are not cheap. Conventional LED bulbs used for home lighting are not as cheap as incandescent or fluorescent lamps, so you can expect them to cost a lot for LED grow lights that can provide life to grows. Although you may find cheaper variants of LED grow lights, consider whether it is really worth it. Cheap does not always save money because of poor quality, it may even cost you more on repairs or replacements. Always choose the most valuable product.
Dimmable
Since many different brands make various variants, it is difficult to choose LED grow lights. Each product will have various functions that may be beneficial or detrimental to different users. The best you may find is the one that provides dimmable light. Dimmable LED grow lights are very effective because you can adjust them as needed. You can set a schedule of when to turn on and off the lights, so you don't have to do it manually. Some even allow you to adjust the intensity and spectrum of the light to suit the grows you are growing.
LED grow light is a revolutionary solution for grow growth. Relying on sunlight to grow grows is not always sufficient, especially for places that experience long sunless winters. You can even grow grows at home. If you plan to buy LED grow lights, be sure to consider the above tips, and Yaorong will find the best tips for your grows.
