Description

Semiconductor irradiation light source device for regulating plant growth

1. Technical field

The utility model belongs to lighting devices, in particular to a semiconductor lighting source device for regulating plant growth.

2. Background technology

With the improvement of people's quality of life, the market demand for off-season vegetables and flowers is becoming more and more vigorous. According to expert predictions, in the next 10 years, a considerable part of vegetables and flowers will come from artificial greenhouses, thus putting forward higher requirements for efficient agricultural greenhouse planting and corresponding indoor lighting. The existing indoor lighting for greenhouse planting mainly uses fluorescent lamps, sodium lamps or tungsten lamps as light sources for plant growth. These traditional light sources have problems such as high energy consumption, short life, poor safety, and single color of the light source, which cannot meet The light regulation requirements of plants in different seasons and different growth stages.

3. Contents of the invention

In view of the defects in the above-mentioned prior art, it is planned to use high-power LEDs (light-emitting diodes, the same below.) for indoor illumination of greenhouse planting, and design and manufacture a semiconductor irradiation light source device for regulating plant growth, so that the indoor lighting of greenhouse planting Illumination can achieve the purpose of surface light source irradiation, long life, low energy consumption, changeable light source color and good safety, so as to meet the needs of light adjustment that is more conducive to plant growth.

The technical scheme adopted in the utility model is as follows.

A semiconductor irradiation light source device for regulating plant growth, including a lampshade and a power cord, characterized in that:

1) It also has lifter connectors, circuit boards, pins, heat sinks and packaged high-power LED lights;

2) The connector of the lifter is fixedly connected to the outer surface of the lampshade, the circuit board is arranged in the cavity of the lampshade, the heat sink is arranged under the circuit board and connected to the lampshade, and the packaged high-power LED lamp is fixed on the heat sink and connected to the circuit through the pins boards in series.

Said packaged high-power LED lamps are preferably alternated with red, white, blue and purple LED lamps, and at least 3 rows of lamp groups are arranged and fixed on the cooling plate.

The basic working principle of the semiconductor irradiation light source device for regulating plant growth of the utility model is: the 220V alternating current is converted into 18-24V direct current through the circuit board, and applied to the positive and negative poles of the LED illuminating lamps connected in series, under the action of the electric field The holes and electrons on the lower positive and negative electrodes enter the active layer and combine to generate excitons, and the excitons release energy to make the luminescent material in the active layer jump from the ground state to the excited state to generate light energy.

The irradiation light source device of the utility model can select the light wave of any color among red, blue, white or purple through the control switch, so as to realize the adjustment of various plant growth requirements; the irradiation can be adjusted through the lifter connected with the connector. The distance between the light source and the plants is to meet the requirements of the plants for different light source intensity; the surface light source can be used to irradiate the plants through the multi-row LED light groups arranged in the greenhouse, so that the light is more uniform and reasonable; its service life is long, up to About 100,000 hours; it is small in size and low in energy consumption, but its luminous efficiency is similar to that of fluorescent lamps and sodium lamps; and its moisture-proof performance is good, which can overcome the unsafe hidden dangers caused by high humidity in the greenhouse. Experiments have proved that it can be widely used in the indoor light adjustment of long-day plants, short-day plants, mid-day plants, long-short-day plants, and short-long-day plants in greenhouses. In future off-season vegetable and flower greenhouse planting, the irradiation light source device of the utility model is an ideal product to replace the traditional irradiation light source, and has realistic and potential market prospects.
