Led Grow Light Heat Dissipation System and Drive Power Supply

Led Grow Light originated from incandescent lamps and later introduced different types of light sources such as low-pressure gas discharge lamps (such as fluorescent lamps) and high-pressure gas discharge lamps (such as sodium lamps, metal halide lamps) with higher luminous efficiency. Since these light sources are mainly developed and produced for white light illumination based on human vision, they do not have special advantages for Led Grow Light, mainly because the spectral range of the light source does not match the needs of plants, and the light. The strength is not suitable, the service life is limited and the energy consumption is high. At present, the mainstream view in the industry believes that the most suitable light source for plant growth lighting is LED. The use of LEDs can obtain light quality consistent with the needs of plants, suitable light intensity, and convenient adjustment ability. It is a very good plant. It has good promotion and application prospects. So what is the Led Grow Light heat dissipation system and drive power supply? Let's take a look at it next.

LED heat conduction and cooling system

The cooling system of the Led Grow Light consists of a heat-conducting plate, a radiator, and a temperature-controlled fan. The heat conduction plate is mainly set for how to dissipate the high heat of the LED light source when it is working. The function of the radiator is to dissipate the high heat emitted by the LED light source by exchanging heat with the air in a large area. Commonly used materials are mainly aluminum. Aluminum has a wide range of uses, good heat dissipation, and the material is easy and the processing is convenient, so it is mostly used for medium and high power; plastic is cheap and easy to process, but the heat dissipation is slightly poor, and it is only suitable for small power. The Led Grow Light temperature control fan is mainly used on the radiator of high-power Led Grow Lights to strengthen the heat dissipation capacity. When the temperature rises too high, the built-in temperature detection is used to start the fan for forced cooling. To facilitate cooperation with the LED light source, a long-life low-voltage DC brushless fan is generally used.

LED constant current driver

The constant current drive power supply of Led Grow Light mainly converts the low-voltage direct current into a constant current, and the voltage meets the voltage requirements of the matched LED light source. The specific composition mainly includes resistance constant current diode ballast and switching constant current source. The low-power Led Grow Light has a relatively simple drive due to its low value, low power, and simple structure, mainly in the form of resistance ballast drive and linear constant current drive. Medium and high power Led Grow Light mainly adopts a constant current switching power supply, which has the advantages of good constant current effect, long life, and safe use. In addition, the mechanical and protective structure is composed of the radiator (also serving as part of the shell), connector (lamp head or terminal), uniform light cover (also serving as part of the shell and protection) and other structures, and it is also required to have functions such as moisture-proof and waterproof. The specific design is covered in the above parts and is not listed separately here.
