Description

  The present invention relates to the technical field of illumination lamps, and more particularly to a plant growing lamp.

  Light is an essential energy source for the photosynthesis of green plants, and plants can grow normally only under the conditions of light irradiation. Plant photosynthesis means that plants absorb sunshine using chlorophyll, This means that organic substances are synthesized using carbon dioxide and water, then converted into chemical energy and stored, and at the same time oxygen gas is released, and the carbohydrates produced by photosynthesis are further converted into starch, fat, etc. and used for life activities. In short, light is essential for plants. In order to promote the growth of plants, lamps are installed in the greenhouse or indoors, the utilization rate of light irradiation of the tubes used is low, and the growth needs of the plants cannot be satisfied, so the growth situation of the plants is deteriorated. When irradiating a plant, irradiation with light having a spectrum necessary for the plant not only promotes growth but also improves the quality of the plant.

  Photosynthetic pigments, moisture, biochemical composition, structure, etc. contained in plants affect the spectral response unique to plants. Chlorophyll a, chlorophyll b and carotenoids in the chloroplast can absorb the visible part of sunlight, chlorophyll a and chlorophyll b absorb the red light region and blue light region, and carotenoid mainly absorbs the blue light region. Healthy plants have low reflectivity in the red and blue light regions. Plant photosynthesis begins when chlorophyll in the chloroplast absorbs red light and blue light as red light, orange light, yellow light, green light, blue light, and purple light as visible light. Not available for plant photosynthesis, effective light is concentrated in the visible light region, among which red light and blue light are the most effective, chlorophyll has a large absorption value in these two types, red light Contributes to the synthesis of carbohydrates by plants and promotes the growth of long-day plants, and blue light promotes the growth of short-day plants and the synthesis of proteins and organic acids.

  In the prior art, the general light bulb and sodium lamp used have high electric cost, the color temperature is different from natural light, and the mercury lamp generates red light because the generated wavelength is between 313 and 430 nm. Since the generated wavelength of the sodium lamp is 565 nm, blue light is not generated, and when a conventional light bulb or sodium lamp is used to irradiate a plant, a large amount of red light or blue light is added to the conventional irradiation light. Plant growth efficiency is low.

  In recent years, LED plant growing lamps have been widely applied to each stage of plant growth as a kind of light source for promoting plant growth, and the manufacturing process of conventional LED plant growing lamps has been greatly improved. However, by being limited by the ratio of the LED illuminant having a wavelength different from the wavelength of the LED illuminant, the acceleration rate for plant growth is low, the effect is low, and the temperature is too high during the operation process. Inability to effectively release the temperature of the lamp causes the light attenuation of the lamp to be serious and adversely affects the service life of the entire lamp.

  The main technical problem to be solved by the present invention is to provide a plant growing lamp that significantly increases the growth rate of plants by irradiating light, and another object of the present invention is to provide a conventional lamp.

Light, red light, green light, blue light; controlled to emit light like red light, orange light, yellow light, green light, light blue light, blue light, violet light, after one scanning cycle is finished, All are turned off, and the above pulse scanning is repeated again.

  Furthermore, the heat radiating portion includes a cylindrical portion having a hollow structure and a plurality of heat radiating fins distributed on the outer periphery of the cylindrical portion, and the heat radiating fin is in a branched shape.

  Furthermore, a plurality of heat dissipation holes are provided in the lamp body, and the heat dissipation holes are long through holes.

  Further, the plant growing lamp further includes a front cover, a transparent member is provided at the front end of the lamp body by the front cover, and a seal ring is provided on a contact surface between the transparent member and the front cover.

  Compared with the prior art, the present invention has the following beneficial effects.

The LED illuminator 2 includes a substrate 4 and a plurality of LED lamp beads provided on the substrate 4, and the LED illuminator 2 is controlled by a spectrum controller to generate various regular pulse periodic spectrum light signals. Is connected to the heat dissipating part 3 through the substrate 4. The LED illuminator 2 is controlled by a spectrum controller using red light (0.4 seconds) → red light, green light, blue light (0.4 seconds) → red light, orange light, yellow light, green light, light blue light, blue light. Light, purple light (0.4 seconds) → blue light (0.4 seconds) → red light (0.4 seconds) → red light, green light, blue light (0.4 seconds) → red light, orange light, It is controlled to emit light such as yellow light, green light, light blue light, blue light, and purple light (0.4 seconds), and it is generated in such a way that different light beams intersect and combine in this order. After one scanning cycle is completed, all light is extinguished (0.8 seconds), a cycle time of light reaction and dark reaction is formed, and after the pulse cycle of 3.6 seconds has elapsed, the above pulse scanning is performed.
