LED plant lights, like all electrical products, will generate heat during use, which will cause an increase in the ambient temperature and its own temperature. If the heat dissipation problem is ignored, it will not only affect the life of the LED plant lights, but may also burn out the lamps, and at the same time It also affects the normal growth of irradiated plants.
Therefore, heat dissipation is a very important link in the manufacturing process of LED plant lights. At present, the main heat dissipation measures adopted by LED plant growth lights are as follows:
(1) Heat dissipation of plant lamp fan:
The principle of using a fan to export the heat generated by the LED plant light to the air is very simple. It is the same as the principle of daily use of computers and TVs. The fan is used to generate convection in the air to ensure that the temperature of the air around the heating element is not Too high, in simple terms, is to use a fan to extract the hot air generated by the LED plant growth lamp and transmitted to the air, and then supplement it with room temperature air to achieve the effect of heat dissipation.
(2) Natural heat dissipation:
Natural heat dissipation is to work directly in the LED plant light without external measures. The main principle is to make the contact area between the entire lamp and the air of the LED plant growth lamp larger, and to use components with better thermal conductivity 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 up, so as to achieve the purpose of heat dissipation of the LED plant light.
At present, heat dissipation fins, lamp housings, system circuit boards, etc. are mainly used. This is also a relatively low cost and effective heat dissipation method, which is widely used in various electrical equipment.
(3) Electromagnetic heat dissipation:
The full name of electromagnetic heat dissipation is electromagnetic jet heat dissipation. Instead of using a fan to generate convection, the hollow cavity of the film is vibrated by electromagnetic vibration, so that the air continues to circulate to achieve the effect of heat dissipation. The technical difficulty is relatively complicated. At present, there are some LED products. application.
Temperature can change the physical shape and chemical structure of an object. Some things get better, such as cooking and cooking, and some become bad, 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 efficiency of electro-optical conversion, we can only increase heat dissipation measures.
It is not difficult to find that the above centralized heat dissipation measures are not conflicting and can be used in combination. It should also be noted that there is no need to superimpose too much, and that the heat dissipation requirements of the LED plant growth lamp can be met, and it can be accepted by the public.
