Why Does the LED Grow Lights Need to Dissipate Heat?

Therefore, in the process of manufacturing LED grow lamps, heat dissipation is an important part. 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 Light 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 fan, the LED plant growth lamp is generated and transmitted to the hot air in the air, and then replenished 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 a better thermal conductivity component to better produce the lamp. 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, heat sink fins, lamp housings, system circuit boards, etc. are mainly used, which is also a relatively low cost and good heat dissipation method, and is widely used in various electrical equipment.

(3) Electromagnetic Heat Dissipation:
Electromagnetic heat dissipation is called electromagnetic jet heat dissipation. Instead of using a fan to convect the gas, 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 Benefits of Reliable Thermal Performance Can Be:

(1) Relatively extending the service life of LED plant lights, the service life of LED plant lights is about 50,000 hours. If the heat dissipation is not good, the internal structure will age faster, and the service life of the lamps will definitely shrink sharply.

(2) Luminous efficiency, any artificial light source has light decay, a very important factor affecting the speed of light decay is temperature, high temperature will accelerate the aging of the material, also use an LED plant lamp, also use 50,000 hours, one In a high temperature environment, where the temperature is a safe light, the crops that are irradiated are undoubtedly the latter with a higher total yield and quality than the former.

(3) The effective heat dissipation configuration of the LED plant lamp can also help to control the ambient temperature. If the heat is not taken for the plant lamp, the local temperature around the lamp is slightly higher for a long time, and the state of plant growth will certainly be different from other places. This is not conducive to the overall temperature control of the greenhouse or plant factory.

As you learned in books, temperature can change the physical shape and chemical structure of an object. But everything has two sides. The use of temperature can be a little helper in our lives, such as cooking and cooking, and sometimes it will bring us losses such as burns and burns. At present, plant lights have become a small helper for plant growth, so when purchasing LED high-power plant lights, the reliability of heat dissipation is an important technical indicator, and the yield and quality of later planted crops will also be directly obvious. Influence, so in addition to considering the price, the heat dissipation of plant lights is also worthy of attention.
