Embodiment Construction

[0011] The specific implementation manner of the present invention will be described below with reference to the accompanying drawings. Such as figure 1 As shown: same as the existing LED desk lamp, it is provided with a printed circuit board 1 and a plurality of LED lamp beads 2 installed on the printed circuit board with the light directed downwards, and a heat sink can be arranged on the back of the printed circuit board 1 or heat dissipation columns, etc., the difference from the prior art is that the multiple LED lamp beads 2 contain blue lamp beads with a wavelength of 400-520nm and red lamp beads with a wavelength of 610-720nm, and the red lamp beads and the blue lamp beads The quantity ratio is 9:1, and the red light beads and blue light beads are evenly staggered. The bottom of the LED lamp bead (2) can be connected to the transparent plate 8 through the connecting column 7, and the nano-scale metal oxide (titanium dioxide, etc.) film3. A support column 4 is connec...

Abstract

The invention discloses an LED lamp for promoting plant growth, which is provided with a printed circuit board (1) and a plurality of LED lamp beads (2) installed on the printed circuit board with the light directed downward, the plurality of LED lamp beads (2) Contain blue light beads with a wavelength of 400-520nm and red light beads with a wavelength of 610-720nm, and the ratio of the number of red light beads to blue light beads is 9:1. The light emitted is soft, closer to natural light and good for vision; the blue light with a wavelength of 400~520nm has the largest absorption ratio of chlorophyll and carotenoids, which can effectively increase the photosynthesis of plants; The low absorption rate can effectively regulate the time of seed germination and flowering; blue light and red light wavelengths act on plants in proportion, which can significantly promote the growth of plants.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp for promoting plant growth which can illuminate, facilitate plant growth, and can also sterilize and purify air. Background technique [0002] At present, LED lamps have been widely used in indoor ceiling lamps, wall lamps, table lamps, outdoor street lamps, garden lamps and other lamps due to their advantages of high efficiency, energy saving and environmental protection. and lampshades. However, the existing LED lamps only seek the most efficient illuminance, and their functions are relatively single. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical problems existing in the prior art, and to provide an LED lamp for promoting plant growth that can illuminate, facilitate plant growth, and can also sterilize and purify air. [0004] The technical solution of the present invention is: an LED lamp for promoting plant grow...
