Background technique

In today's society that pays more and more attention to energy saving and emission reduction, LED lamps are being used more and more in lighting because of their advantages of high efficiency, low consumption, energy saving, environmental protection, and long life. However, the photoelectric conversion efficiency of ordinary high-power LED lamps is about 20%-30%, and about 70% of the electric energy is converted into heat energy. The mechanism of LED light emission is to generate light by the transition of electrons between energy bands, and its spectrum does not include the infrared part, so its heat cannot be dissipated by radiation. If there is no good heat dissipation system, working for a long time will cause the junction temperature of the LED chip to be too high, which will speed up the light decay and shorten the service life. LED plant growth lamp is an artificial light source that uses LED (light-emitting diode) as the illuminant to meet the lighting conditions required for plant photosynthesis. The light environment is one of the important physical environmental factors that are indispensable to the growth and development of plants. Through the adjustment of light quality, controlling the formation of plants is an important technology in the field of facility cultivation; plant growth lights are more environmentally friendly and energy-saving. LED plant lights give plants Provide photosynthesis, promote plant growth, shorten the time for plants to flower and bear fruit, and increase production. In modernization, it is an indispensable product of crops.

However, for some plants that require high light intensity, the power of the lamp is also relatively large, and the problem of heat dissipation is prominent, and the air-cooled heat dissipation makes the heat gather above or around the plants, which is not conducive to the ambient temperature of plant growth in greenhouses or facility agricultural buildings. adjustment. There is a need to develop more efficient cooling technologies while reducing lamp costs.
