Three Major Ways of Heat Dissipation for LED Grow Light
Like all electrical products, LED plant lights generate heat during using, which will cause an increase in ambient temperature and temperature. If the problem of heat dissipation is neglected, it will not only affect the service life of LED plant lights, but also burn out the lamps. It also affects the normal growth of irradiated plants.
Therefore, in the manufacturing process of LED plant lights, heat dissipation is a very important link. At present, the main heat dissipation measures adopted by LED plant growth lamps are as follows:
(1) Plant lamp fan cooling:
The principle of using a fan to transfer the heat generated by the LED plant lamp into the air is very simple. The same as the heat dissipation principle of the computer and TV used in daily use, the fan is used to convect the air to ensure that the air temperature around the heating element is not too high, simply by using a fan to generate the LED plant growth lamp and transfer it to the hot air in the air, and then replenish it with normal temperature air to achieve the effect of heat dissipation.
(2) Natural heat dissipation:
Natural heat dissipation means no need for external measures, and it is directly working inside the LED plant lamp. The main principle is to make the LED plant growth lamp have a larger contact area with the air and use the better thermal conductivity components to better produce the lamps. The heat is transferred to the air, and then through natural convection, that is, the hot air rises, and the cold air fills the position, thereby achieving the purpose of cooling the LED plant lamp.
At present, this method come true by the main use of heat sink fins, lamp housings, system circuit boards, etc. And its effect is also good, Natural heat dissipation is now widely used in a variety of electrical equipment.
(3) Electromagnetic heat dissipation:
Electromagnetic heat dissipation is called electromagnetic jet heat dissipation. Instead of using a fan to convect the air, electromagnetic vibration is used to drive the cavity in the film to vibrate, so that the air continuously circulates to achieve the effect of heat dissipation. The technical difficulty is complicated. At present, some LED products are available. application.
The temperature can change the physical shape and chemical structure of the object, and it has become better, such as cooking and so it has deteriorated, such as burns and burns. When using LED plant lights, we don't want it to generate so much heat. In addition to improving the electro-optical conversion efficiency, we can only increase the heat dissipation measures.
It is not difficult to find out that the above concentrated heat dissipation measures are not conflicting. They can be combined and used, and it is also necessary to pay attention not to superimpose measures to the LED plant growth lamp. When it meet the heat dissipation requirements of the LED plant growth lamp, it would be just right.
