[0035] The mounting block 11 is provided with a lamp 111 and a light-transmitting body 113, wherein the light-transmitting body 113 includes a concave lens portion 114 and a prism portion 115;

[0036] The light-transmitting plate 12 has a plurality of movable plates 121 movably disposed thereon. The movable plates 121 are assembled for the following two states:

[0037] In the first state, the lamp head 1 is fixed on the lamp post 2, the lamp post 2 directly illuminates the concave lens portion 114, and the movable plate 121 rotates and faces the side of the lamp 111;

[0038] In the second state, the lamp head 1 rotates relative to the lamp post 2, the lamp 111 rotates and illuminates the prism portion 115, and the plurality of movable plates 121 rotate and switch to a horizontal state and leave gaps for red light and blue light to pass through.

[0039] Specifically, the lamp 111 is rotatably mounted on the mounting block 11 .

[0040] Furthermore, when someone is checking the status of the plants, the lamp head 1 is fixed on the lamp post 2, and the side of the movable plate 121 faces the lamp 111. At this time, the light emitted by the lamp 111 is scattered by the concave lens portion 114 and then passes through the light-transmitting plate 12 to illuminate the plants. The white light directly illuminates the plants, making it convenient to check the status of the plants; when no one is around, the lamp head 1 rotates relative to the lamp post 2, and the lamp 111 rotates relative to the mounting block 11. The light emitted by the lamp 111 illuminates the prism portion 115, and the white light is scattered through the prism portion 115, and lights of different colors are respectively illuminated at different positions of the light-transmitting plate 12, and the movable plate 121 rotates and switches to a horizontal state. The movable plate 121 absorbs other colored lights and only leaves gaps for red light and blue light to pass through, and the red light and blue light respectively illuminate the plants on both sides of the lamp post 2. The lamp head 1 rotates continuously so that the plants are alternately illuminated by red light and blue light, thereby promoting plant growth.

[0041] In the above technical scheme, when someone is checking the status of the plants, the lamp head 1 is fixed on the lamp post 2, and the side of the movable plate 121 faces the lamp 111. At this time, the light emitted by the lamp 111 is scattered by the concave lens part 114 and then passes through the light-transmitting plate 12 to irradiate the plants. The white light directly irradiates the plants, which is convenient for checking the status of the plants; when no one is around, the lamp head 1 rotates relative to the lamp post 2, and the lamp 111 rotates relative to the mounting block 11.

The movable plate 121 absorbs other colored lights and only leaves gaps for red light and blue light to pass through, and the red light and blue light respectively irradiate the plants on both sides of the lamp post 2. The lamp head 1 rotates continuously so that the plants are alternately irradiated with red light and blue light, which promotes plant growth.
