A plurality of support members, such as pipes, are disposed between, and provide mechanical support for, two hydroponic cultivation units on every two neighboring levels. A light source is disposed over a bottom side of one hydroponic cultivation unit on an upper level and can emit a plant-compatible light to support growth of the plants being cultivated on another hydroponic cultivation unit on a level immediately below the upper level. The hydroponic cultivation system can achieve a vertical recycling of the culture solution.

Abstract: An LED plant illumination lamp module includes at least two light source modules and two lamp module cases located at both ends of the light source modules. Each of the light source modules includes a lamp tube, a circuit board mounted inside the lamp tube, and LED lamp beads fixed on the circuit board. At least two lamp tube insertion slots are arranged on one side of each of the lamp module cases, and two ends of the lamp tube are respectively inserted into the lamp tube insertion slots on the lamp module cases. At least one of the lamp module cases is provided with an LED power supply, and an output end of the LED power supply is connected to the circuit board inside the lamp tube.

Abstract: A plant illumination optical device includes two LED lamp bodies. Each of the LED lamp bodies includes a reflector and an LED lamp located at an inner side of the reflector, and an angle between the central light rays of the two LED lamp bodies is adjustable. A plant cultivation device contains the plant illumination optical device. The plant illumination optical device and the plant cultivation device can reflect the light beyond the planting area to the planting area and can supplement the illumination on both sides of the illumination centerline, thereby avoiding light waste, improving energy efficiency, improving the illumination uniformity in the planting area, and improving planting quality of the planting area.

Abstract: A radiator and a plant illumination lamp containing the radiator. The radiator includes a heat-radiating baseplate configured for fixing a heat source, and heat-radiating side plates connected to the heat-radiating baseplate. The heat-radiating side plates each are provided with a plurality of heat-exchanging through grooves running through the heat-radiating side plates. The heat-exchanging through groove forms a heat potential difference, so that under the influence of the heat potential difference, the cold air outside the radiator passes through the heat-exchanging through groove on the heat-radiating side plates, and then flows out through a hot air chamber and an air outlet at an upper end of the hot air chamber after exchanging heat with the heat-exchanging through groove on the heat-radiating side plates, so as to form a strong natural air convection.

Abstract: A liquid cooling module of an LED lamp, including a cooling body, two plugs and a heat source. The cooling body is formed with connected liquid flowing passages, and has the two plugs coupled to the two sides thereof. An inlet of each liquid flowing passage and an outlet of the adjacent liquid flowing passage are located at the same side of the cooling body. The inlet of the first liquid flowing passage is connected to an inlet hole of the plug at the same side. The liquid inlet of each liquid flowing passage besides the first one is connected to the outlet of the previous liquid flowing passage by a connecting groove of a corresponding plug. The outlet of the last liquid flowing passage is connected to an outlet hole of the plug at the same side.

Abstract: A planting device, a multilayer stereo-planting system using the planting device, and a planting system of a plant factory using the multilayer stereo-planting system are provided. The planting device includes the planting tray and the planting board which can be moved as a whole. The nutrient solution inlet and the nutrient solution outlet are located on the same side of the planting tray. The multilayer stereo-planting system includes the support rack and the nutrient solution supply system installed on the support rack. The planting device can be detachably installed on the support rack as a whole. The planting tray and the planting board of the planting device can be taken out and placed in together, protects the plant seedlings from injuries, and avoids the leakage phenomenon of the nutrient solution.

Abstract: The disclosure discloses a bicolored plant cultivation apparatus. It contains two parts: a cultivation tank and a planting plate which can be assembled as a cavity for storing nutrient solutions and nutrient aerosols, or both can be used separately. In order to create a dark environment inside the cavity, the surface of inner bottom and lateral walls of the cultivation tank, the lower surface of the planting plate, or at least one of them will be coated with one layer of light blocking material. The principle behind the disclosure is to minimize the light intensity below the planting plate in order to provide a low light environment which is suitable for plant root growth and inhibits the alga growth at the same time. The preparation methods of the light-blocking layer include coating, injection moulding, lamination, adhesion and spraying.

Abstract: A configurable hydroponic cultivation device includes a tank. The tank includes at least one separation bar and at least one removable dam member. The at least one separation bar is disposed on a bottom side of the tank and is configured to separate the tank into a plurality of trough regions. The at least one removable dam member is configured to be removably mounted in the tank to thereby block the culture solution from flowing therethrough. The at least one separation bar and the at least one removable dam member are configured to allow a configurable passageway for the culture solution flowing in the tank. Due to its modular features, the configurable hydroponic cultivation unit can be stacked one another to form a multi-level hydroponic cultivation system, which achieves a vertical recycling of the culture solution.
