What is the heat dissipation method of LED plant light?
Like all electrical products, LED plant lights will generate heat during use, which will increase the ambient temperature and their own temperature. If the problem of heat dissipation is ignored, it will not only affect the life of the LED plant lights, but may also burn out the lamps. It also affects the normal growth of irradiated plants.
The characteristics of LED plant lights: rich in wavelength types, just in line with the spectral range of plant photosynthesis and light morphology; the half-width of the spectral wave width is narrow, and pure monochromatic light and compound spectra can be combined as needed. LED plant light manufacturers do not use fertilizers at all for organic planting, but organic fertilizers can be used: farmhouse fertilizers, mineral fertilizers, biological bacteria fertilizers, etc. after high-temperature fermentation and harmless treatment. Due to the limitation of this kind of fertilization, the growth cycle of plants is bound to be affected, and the current large demand in the market appears to be in short supply. Therefore, shortening the production cycle is one of the methods.
The LED plant lamp has strong roots, encourages growth, adjusts the flowering period and flower color, promotes fruit ripening and coloring, and enhances the taste and quality of the fruit! 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. Plant light fan heat dissipation: The principle of using a fan to export the heat generated by 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 heat generation. The temperature of the air around the original is not too high. Simply put, the hot air generated by the LED plant growth lamp and transferred to the air is drawn out by a fan, and then normal temperature air is added back to achieve the effect of heat dissipation.
2. Natural heat dissipation: Natural heat dissipation means that you don’t need external measures, and work directly in the LED plant light. The main principle is to make the contact area of the whole lamp and the air of the LED plant growth light larger, and use components with better thermal conductivity. It is good to transfer the heat generated by the lamp 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 film cavity 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. Some LED products have been applied. Temperature can change the physical shape and chemical structure of an object. Some will change for the better, such as cooking and cooking, and some will deteriorate, such as burns and burns.
