LED plant lamp with heat dissipation and waste heat recovery functions

Abstract

The invention discloses an LED plant lamp with the heat dissipation and waste heat recovery functions. The LED plant lamp comprises a waste heat recovery device, a support, a control box, a control circuit, a constant-current power source, flat plate heat dissipaters, a high-efficiency reflective cover, heat sensors, copper screws, a light outgoing lens, a large-power LED light source, an aluminum-based printed circuit board and heat conducting glue. The waste heat recovery device is installed at the top of the support, the control box is arranged on the right side of the support, and the support is fixedly connected with the constant-current power source. The constant-current power source is installed on the high-efficiency reflective cover. The LED plant lamp with the heat dissipation and waste heat recovery functions has the beneficial effects of being small in size, low in weight, solid, long in service, special in wavelength, low in drive voltage, high in light efficiency, small in energy consumption, safe, reliable, durable, not prone to color attenuation and the like; the waste heat recovery device is arranged, redundant heat energy can be recovered and converted into electric energy, and resources are saved; and the flat plate heat dissipaters are installed on the high-efficiency reflective cover, so that the heat dissipation rate of the LED plant lamp is increased.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED plant lamp with functions of heat dissipation and waste heat recovery. Background technique [0002] Sunlight is one of the necessary logistics conditions for plant growth and development. However, sunlight cannot illuminate plants 24 hours a day, resulting in a decrease in plant growth efficiency. LED light sources have the advantage of rich wavelength types. The light energy radiated by LED lamps matches the spectral range required for plant photosynthesis. Therefore, various LED lamps can be combined to obtain pure monochromatic light or composite light. LED plant lights focus on specific wavelengths of light to irradiate plants in a balanced manner. It can not only adjust the flowering and fruiting of plants, but also control the plant height and nutritional content of plants. Therefore, it is widely used in plant cultivation, facility gardening, and industrial seedli...

Problems solved by technology

[0003] Different plants have different needs for light. The LED plant lights in the prior art have poor heat dissipation performance and do not have the function of recovering waste heat. Because traditional light sources are generally full-band, if fluorescent lamps are used as light sources, they need to be filtered to obtain Specific wavelengths of light are required, which will reduce light utilization and may be converted into heat for filtered light sources, thus failing to meet the needs of plant growth
