Detailed explanation of the three main heat dissipation methods for LED lights
(1) Plant light fan heat dissipation: The principle of using the fan to output the heat generated by the LED lamp to the air is very simple. Just like the heat dissipation principle of computers and televisions used every day, air convection is generated through a fan to ensure that the air temperature around the heating element is not too high. Simply put, the hot air generated by the LED lamp is sent into the air with a fan, supplemented by room temperature air to achieve the heat dissipation effect.
(2) Natural heat dissipation: Natural heat dissipation refers to working directly inside the LED lamp without external measures. The main principle is to make the whole lamp of the LED lamp have a large contact area with the air, and the components with better thermal conductivity are used. In order to better transfer the heat generated by the lamp to the air, and then through natural convection, that is, hot air rises, cold air is compensated, so as to achieve the purpose of heat dissipation of LED lamps.
(3) Electromagnetic heat dissipation: Electromagnetic heat dissipation is called electromagnetic jet heat dissipation. Instead of using a fan for gas convection, electromagnetic vibration is used to drive the vibration of the membrane cavity to circulate air and achieve the effect of heat dissipation. The technical difficulty is complicated. Some LED products are used. Temperature can change the physical form and chemical structure of an object, some are better, such as steaming and cooking, and some are not, such as scalding and burning. When using LED lights, we don't want it to generate too much heat. In addition to improving the electro-optical conversion efficiency, only heat dissipation measures can be increased.
