A solar-powered LED system that prompts peppers to bloom

technical field

The invention relates to the field of plant cultivation.

Background technique

LED (Light-Emitting Diode), also known as light-emitting diode, is made of Ⅲ-Ⅳ group compounds, such as GaAs (gallium arsenide), GaP (gallium phosphide), GaAsP (gallium arsenide phosphide) and other semiconductor materials. It is a PN junction. It uses a solid semiconductor chip as a light-emitting material. When a forward voltage is applied to both ends, the carriers in the semiconductor recombine, and excess energy is released to cause photon emission to produce visible light. According to the luminous intensity and working current, it can be divided into ordinary brightness LEDs (luminous intensity <10mcd), high-brightness LEDs (luminous intensity between 10 and 100mcd) and ultra-high brightness LEDs (luminous intensity >100mcd), among which super The lifespan of high-brightness LED can reach more than 50,000 hours, and the light decay is only 30%. LED-related products have been available as early as the early 1960s. In 1962, the world's first GaAsP red LED (λp=650nm) was successfully developed, and then yellow LEDs began to appear, but at this stage, LED light sources were limited to signs and viewing. applications in other fields. In the mid-1980s, high-brightness LEDs began to be launched. In 1993, blue and green LED products were successively developed. In 1996, white LEDs were also successfully developed. However, due to the influence of factors such as brightness and price, LED has not been popularized and applied as a general light source for a long time. In the past 10 years, with the continuous deepening of international research on semiconductor light-emitting materials, the continuous improvement of LED performance, the sharp drop in price, and the successive introduction of high-power LED products, the popularization of LED has gradually become possible.

At present, LEDs have been widely used in many fields such as automobiles, communications, information, traffic signals, home appliances, lighting, and biomedicine. Compared with other artificial light sources such as high-pressure sodium lamps, incandescent lamps, and fluorescent lamps, the advantages of LEDs are: 1. The power supply voltage is lower, and the power supply voltage is only 2~24V, which is safer than using high-voltage power supplies; 2. Energy saving and high efficiency, power consumption 3. It can emit monochromatic light with narrow light wave, such as infrared, red, orange, yellow, green, blue, etc., and can also be used according to different Any combination is required; 4. The cold light source with low heat generation characteristics can irradiate plants at close range and improve space utilization; 5. It can emit pulsed light in a very short time, and the response time is fast; 6. Small size, compact structure, and stability Strong; 7. No pollution, as an all-solid luminous body, does not contain metal mercury, impact resistance, not easy to break, and waste can be recycled, it is a green lighting product; 8. Long life, up to 50,000 hours, is a general lighting Dozens of times that of lamps. In recent years, with the continuous innovation of optoelectronic technology, LED is moving towards the goal of high brightness and low cost, and the effect of energy saving is remarkable. The unique performance of LED light source provides an effective development space for its application in the field of plant cultivation.

Contents of the invention

In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a LED system based on solar energy to promote flowering of peppers. The system includes a solar energy collection board and several light boards; the solar collection board is installed outside the greenhouse, and the glass window on one side of the collection board is a sawtooth structure; the four vertices on the other side are respectively equipped with universal joints, and each universal joint It is connected to one end of the telescopic rod, and the other ends of the four telescopic rods are connected to the same fulcrum; the telescopic rod is controlled by a stepping motor to expand and contract; the light panels are placed in layers in the greenhouse, and the distance between each layer is 30 cm; The lamp board includes a base with several jacks and a number of lamp beads, the lamp beads are inserted into the jacks of the base, the base jacks are connected to the positive and negative poles of the power supply, and a number of 720nm electromagnetic radiators are arranged around the base , the lamp beads include: 630nm red LEDs and 460nm blue LEDs, the red LEDs and blue LEDs are evenly arranged alternately, with a ratio of 10:1; several fans are arranged on the side of the base, and ventilation holes are opened on the top surface of the base .

Beneficial effects: the solar collection board can be adjusted at different angles according to needs to maximize the use of solar energy; the glass window on the sunny side is a sawtooth structure, which increases the contact area of sunlight; the telescopic rod is controlled by a stepping motor, which is more precise; The plants bloom quickly and vigorously; fans are installed on the side to blow heat to the middle, and the heat is discharged upward through the vent holes on the top surface to minimize the impact of heat on the plants.
