[0002] China ranks first in the world in terms of the area of protected agriculture (horticulture), accounting for about 80% of the total area of protected agriculture (horticulture) in the world. However, more than 98% of the facilities are still solar greenhouses or small and medium-sized arched greenhouses with an area of only 300 m2 - 600 m2, and the large-scale intelligent greenhouses account for less than 2%. Taking the agricultural products produced in the vast solar greenhouses / small and medium-sized arched greenhouses as an example, it is necessary to achieve continuous supply throughout the year, have a good taste, and be nutritious.

[0003] However, in the cultivation of solar greenhouses / small and medium-sized arched greenhouses in autumn and winter in China, the growth period of crops is often accompanied by overcast, rainy, snowy, foggy and hazy days, resulting in weak light, low temperature and high humidity, which lead to the phenomena of weak growth of cultivated crops, increased flower and fruit drop of fruit vegetables, slow fruit development, and reduced nutrient content, greatly reducing the yield and quality of agricultural products.

[0004] Therefore, in the production of autumn and winter crops in solar greenhouses / small and medium-sized arched greenhouses, additional artificial supplementary lighting can improve the quality of agricultural products produced to a certain extent and ensure stable and high yields.

[0005] However, there are still some deficiencies in the existing plant lighting systems on the market: the existing plant lights are all single-sided light-emitting, and moreover, the connection between the existing plant lights and the power supply wires is relatively troublesome, and it is necessary to strip the power supply wires and then manually make electrical connections.

[0006] Therefore, in the patent application of the present utility model, the applicant has carefully studied a plant lighting system to solve the above problems. Summary of the Utility Model

[0061] All the plant lamps 30 are arranged at intervals. The output ends of the constant voltage power supply 40 are respectively connected to the two DC constant voltage power supply lines 10. Each plant lamp 30 is connected to the two DC constant voltage power supply lines 10 through a puncture connector 20. In this embodiment, the two DC constant voltage power supply lines 10 are respectively a DC constant voltage positive power supply line and a DC constant voltage negative power supply line; the constant voltage power supply 40 supplies power to the DC constant voltage positive power supply line and the DC constant voltage negative power supply line respectively. Each plant lamp 30 is respectively connected to the DC constant voltage positive power supply line and the DC constant voltage negative power supply line through a puncture connector 20 to be powered and each plant lamp 30 is connected in parallel.

[0062] The puncture connector 20 includes a plastic main body 21, a wire clamping block 22 detachably connected to the plastic main body 21, a conductive terminal 24 located in the plastic main body 21, and a terminal fixing sleeve 23 detachably connected to the lower end of the plastic main body 21;

[0063] The upper end surface of the plastic main body 21 is recessed downward to form a first installation cavity 211, and the inner wall of the first installation cavity 211 is provided with a first internal thread 212. The lower end surface of the plastic main body 21 is recessed upward to form a second installation cavity 213, and the inner wall of the second installation cavity 213 is provided with a second internal thread 214;

[0064] In this embodiment, the plastic main body 21 includes an upper end connection part 215, a transition chamfer part 216, a polygonal connection part 217, and a lower end connection part 218 which are arranged in sequence from top to bottom;

The outer diameter of the upper end connection portion 215 is greater than the outer diameter of the lower end connection portion 218. The second installation cavity 213 is recessed upward from the lower end surface of the lower end connection portion 218.

[0066] The lower end of the conductive terminal 24 is electrically connected to the plant lamp 30. In this embodiment, the lower end of the conductive terminal 24 has a bottom conductive connection end 242 for electrically connecting to the electrical connection portion of the power supply line 31 of the plant lamp 30.

The terminal fixing sleeve 23 includes a columnar portion 233 and a handle portion 234 arranged in sequence from top to bottom.

[0068] When one of the power supply lines 31 of the plant lamp 30 passes through the third installation cavity 232 from bottom to top and extends into the second installation cavity 213 to be electrically connected to the bottom conductive connection end 242, the plastic body 21 is connected to the terminal fixing sleeve 23. The second external thread 231 is adapted to the second internal thread 214. The bottom conductive connection end 242 extends into the third installation cavity 232. By externally rotating the terminal fixing sleeve 23, the electrical connection portion of one of the power supply lines 31 of the plant lamp 30 is tightly connected to the bottom conductive connection end 242.

[0069] The upper end of the conductive terminal 24 has a top conductive connection end 241. The top conductive connection end 241 extends into the first installation cavity 211.

All the LED lamps 321 are arranged at intervals along the length direction of the lamp board 32 where they are located. All the LED lamps 321 are connected to the piercing connector 20 through two power supply lines 31. The two lamp boards 32 are installed in the transparent tube 33. As Figure 1 or Figure 9 shown, all the plant lamps 30 are arranged vertically or horizontally. Preferably, the transparent tube 33 is a transparent PC tube.

[0073] The design key point of the present utility model lies in that mainly through the design of the piercing connector, the electrical connection between the plant lamp and the DC constant voltage power supply line does not require welding, improving the electrical connection efficiency between the plant lamp and the DC constant voltage power supply line. In particular, the plant lamp can emit light relatively from the side, and the overall compactness is better;

[0074] Secondly, through the terminal fixing sleeve, it is convenient for the detachable connection between the power supply line of the plant lamp and the piercing connector, further improving the installation efficiency.

[0075] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
