Plant light source

The present invention relates to a plant light source, and more particularly to a plant light source using a light-emitting diode (LED).

The growth and development of plants depends on photosynthesis, while photosynthesis requires irradiation of light. The photosynthesis of plants in nature is dependent on sunlight. However, with the development of plant cultivation techniques, artificial greenhouses such as plant greenhouses and plant factories often require artificial light sources for auxiliary irradiation or rely entirely on artificial light sources for irradiation.

Studies have pointed out that the absorption spectrum of plant photosynthesis is selective. Traditional plant illumination lamps are usually fluorescent or sodium lamps. The disadvantages are high energy consumption and short life, and the emission spectrum is only partially consistent with the plant photosynthesis spectrum. Low light utilization.

The use of LED lamps as plant lights not only has the advantages of low energy consumption and long life, but also can be selected for wavelengths suitable for photosynthesis of plants.

At present, the common plant LED lamp is an integrated LED plant lamp, such as LED light bar or LED light box. However, the integrated LED plant lamp has determined the intensity and illumination range of the light source when the production is completed. Therefore, if the intensity and the illumination range of the light source are to be adjusted according to the plant species or the stage of plant growth, the entire set of LED plant lamps must be Replacement, so it is not easy to adjust the strength and distribution of the light source according to the actual plant irradiation needs.

The lamp cap is disposed on the other side of the lamp housing. The LED driver is electrically connected to the COB type LED light source and the lamp holder.

According to an embodiment of the present invention, in the above plant light source, the lamp housing comprises a lamp housing body and a plurality of heat dissipation fins. The heat dissipation fins are disposed on the lamp housing body.

According to an embodiment of the present invention, in the above plant light source, the lamp housing further includes a carrier plate disposed on one side of the lamp housing body, and the COB type LED light source is disposed on the carrier board.

According to an embodiment of the present invention, in the above plant light source, the COB type LED light source further includes at least one blue LED die.

According to an embodiment of the present invention, in the above plant light source, the ratio of the number of red LED dies to blue LED dies is, for example, 1:1 to 10:1.

According to an embodiment of the present invention, in the above plant light source, the LED driver is, for example, an AC-DC LED driver.

According to an embodiment of the present invention, in the above plant light source, the LED driver is disposed, for example, in the lamp housing.
