Description

LED high-efficiency plant growth lamp

Technical Field

The utility model provides a vegetation lamp, in particular to adopt red and blue double-colored LED and white light LED and have the reflector panel and can adjust the high-effect vegetation lamp of LED that light gathered together the region.

Background

A Light-emitting diode (LED) is a semiconductor device, which is often used as an indicator Light or a display panel at first time, but with the appearance of a white LED, the LED is also used as a lighting device, which has the advantages that the conventional incandescent Light source cannot compare with the LED, such as high efficiency, energy saving, long service life, and difficulty in damage, etc., and the LED can emit a single color and discontinuous Light when a forward voltage is applied, which is one of the electroluminescent effects.

It is known that the semiconductor material used in LED basically determines the wavelength emitted by the LED, AlGaAs (aluminum gallium arsenide) is suitable for manufacturing high brightness red and infrared LEDs, AlGaInP (aluminum indium gallium phosphide) is suitable for high brightness red, orange, yellow and yellow-green LEDs, GaInN (indium gallium nitride) is suitable for high brightness deep green, blue, violet and ultraviolet LEDs, white LEDs are formed by blue LEDs and yellow fluorescent materials, and multicolor LEDs are constructed by encapsulating the above two or more materials in one LED and controlling the input voltage, so that a single LED can be used to emit R, G, B (red, green, blue) or other three colors of light.

However, the plant lamp is a lamp for providing sufficient illumination to plants to increase the growth rate of the plants, and conventionally, an incandescent lamp is used as a light source for illumination. Furthermore, the color temperature and lumens of plant lamps are seen from the human eye, but plant photosynthesis is affected by the spectrum; wherein, when the spectrum range is 280-315 nm, the influence on the plant morphology and the physiological process is extremely small; when the spectrum range is 315-400 nm, the chlorophyll absorption is less, the photoperiod effect is influenced, and the stem elongation is prevented; when the spectral range is 400-520 nm, blue light is presented, the absorption ratio of chlorophyll to carotenoid is the largest, and the influence on photosynthesis is the largest; when the spectrum range is 520-610 nm, green light is presented, and the absorption rate of the pigment is not high; when the spectrum range is 610-720 nm, the red light is presented, the chlorophyll absorption rate is low, and the photosynthesis and the photoperiod effect are obviously influenced; when the spectrum range is 720-1000 nm, the absorption rate is low, the cells are stimulated to be prolonged, and the flowering and seed germination are influenced; the spectral range is larger than 1000nm and is converted into heat energy.

Therefore, the influence of the light with different wavelengths on the photosynthesis of the plant is different, the wavelength of the light required by the photosynthesis of the plant is 400-720 nm, wherein the blue light with the wavelength of 400-520 nm and the red light with the wavelength of 610-720 nm have the largest contribution to the photosynthesis, and the ratio of the green light with the wavelength of 520-610 nm to the absorption of plant pigments is very low. The white light LED lamp uses a blue core to excite yellow fluorescent powder, thereby generating a visual white light effect. In energy distribution, two peaks exist in a 445nm blue light region and a 550nm yellow-green light region, and 610-720 nm red light required by plants is very lacking, so that the plants are unfavorable to grow under the irradiation of a white light LED.

According to the principle, the plant lamp is made into a red-blue combination mode, a full-blue mode and a full-red mode at present so as to provide light rays with two wavelengths of red and blue and cover a wavelength range required by photosynthesis, wherein the effect of the plant lamp combined by red and blue is better; however, the conventional plant lamp with red and blue combination mainly includes a plurality of red LEDs and blue LEDs arranged in a single lamp tube to emit mixed red and blue light, but the emitted light is divergent and cannot be concentrated in a plant growth area, and the mixed red LEDs and blue LEDs are not uniform, so that the plant growth speed is slowed, light spots are easily formed, ultraviolet light and infrared light which are useless for plant growth are radiated, a large amount of electric energy is wasted, and the durable service life is short.
