When someone is checking the status of the plants in the device, the lamp head is fixed on the lamp post, and the side of the movable plate faces the lamp. At this time, the light emitted by the lamp is scattered by the concave lens part and then passes through the light-transmitting plate 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 rotates relative to the lamp post, and the lamp rotates relative to the mounting block. The light emitted by the lamp illuminates the prism part, the white light passes through the prism part and is scattered, and lights of different colors are respectively illuminated on different positions of the light-transmitting plate, and the movable plate rotates and switches to a horizontal state. The movable plate absorbs other colored lights and only leaves gaps for red light and blue light to pass through. The red light and blue light respectively illuminate the plants on both sides of the lamp post, and the lamp head rotates continuously so that the plants are alternately illuminated by red light and blue light, thereby promoting plant growth.

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-14As shown, an energy-saving street lamp luminous angle adjustment device comprises a lamp pole 2 and a mounting shell 1 fixedly mounted on the lamp pole 2 and offset, wherein the mounting shell 1 is movably provided with a movable ring 115, a lamp 11 emitting strip-shaped parallel light, and reflective walls 149 located on both sides of the lamp 11, a light guide 111 is slidably provided on the movable ring 115, and the light guide 111 comprises a prism portion 112 and a reflective portion 113 in the shape of a triangular prism corresponding to the two reflective walls 149, and the mounting shell 1 is provided with a plurality of light guides 111, wherein the light guide 111 comprises a prism portion 112 and a reflective portion 113 in the shape of a triangular prism corresponding to the two reflective walls 149, and the light guide 111 is provided with a plurality of light guides 111, wherein the light guide 111 comprises ... A first light outlet 143 and a second light outlet 144 are respectively opened at the bottom, and the position of the movable ring 115 relative to the mounting shell 1 is changed so that the light emitted by the lamp 11 is dispersed through the prism portion 112, and the red light and the blue light are alternately emitted from the first light outlet 143 and the second light outlet 144, and the light guide 111 moves relative to the mounting ring so that the reflective portion 113 reflects the light emitted by the lamp 11, and the two beams of reflected light cross and are emitted from the first light outlet 143 and the second light outlet 144 respectively.

[0022] Specifically, the lamp 11 is a strong light lamp. If the strong light emitted by it directly contacts the plants, it is easy to burn the plant leaves. The red light and blue light separated from the strong light after dispersion can avoid burning the plant leaves and promote plant growth.

[0023] In the above technical solution, when promoting plant growth, the strip of parallel strong light emitted by the lamp 11 is irradiated on the prism part 112 of the light guide 111. The strip of parallel strong light passes through the prism part 112 and is dispersed. Light of different wavelengths is separated. Red light is emitted from the first light outlet 143, and blue light is emitted from the second light outlet 144. The red light and the blue light irradiate plants in different areas. After working for a period of time, the movable ring 115 drives the light guide 111 to rotate. The light emitted by the lamp 11 is dispersed when passing through the prism part 112, so that the red light and the blue light can be emitted from the second light outlet 144 and the first light outlet 143 respectively, so that the plants facing the lamp 11 can be alternately irradiated by the red light and the blue light. And the irradiated object is always the plant, avoiding energy waste; when the staff needs to observe the growth status of the plant, the light guide 111 moves relative to the movable ring 115, so that the triangular prism-shaped reflecting part 113 on the light guide 111 is opposite to the lamp 11, and the parallel light emitted by the lamp 11 is divided into two parts by the reflecting part 113 and reflected, and the reflected light contacts the reflecting wall 149 and is reflected again, and the two beams of reflected light pass through the first light outlet 143 and the second light outlet 144 respectively, and the two beams of light cross, and the light beam emitted from the first light outlet 143 illuminates the plant, which is convenient for the staff to observe the growth status of the plant, and the light beam emitted from the second light outlet 144 illuminates the road next to the lamp pole 2, which is convenient for the staff to move.

[0024] As a further embodiment of the present invention, a notch is provided at the bottom of the mounting shell 1 , and a baffle 147 is rotatably disposed in the notch to divide the notch into a first light outlet 143 and a second light outlet 144 .

[0025] Specifically, when promoting plant growth, the baffle 147 blocks the middle part of the notch at the bottom of the mounting shell 1, absorbs the light beam between the red light and the blue light, and prevents this part of the light beam from affecting the plant's absorption of red light and blue light; when the staff observes the growth status of the plants, the baffle 147 rotates relative to the mounting shell 1, from a horizontal state to a vertical state, so that the first light outlet 143 and the second light outlet 144 divided by it are enlarged, making it convenient for the light reflected by the reflective wall 149 to be emitted from the mounting shell 1, thereby facilitating the staff's movement and checking of the plant growth status.

[0026] As another embodiment further provided by the present invention, the lamp 11 is offset in the mounting housing 1 , and the position of the movable ring 115 changes relative to the mounting housing 1 to deflect the lamp 11 .

[0027] Specifically, the position of the movable ring 115 includes a first position and a second position, and the two positions are 180° apart. The lamp 11 is offset inside the mounting shell 1 to facilitate the light emitted by it to illuminate the plant after being dispersed.

[0028] Furthermore, when the movable ring 115 is in the first position, the lamp 11 is vertically downward, and the light emitted by the lamp 11 is dispersed in the process of passing through the prism part 112, and the red light is emitted from the first light outlet 143, and the blue light is emitted from the second light outlet 144, and the red light and the blue light illuminate the plants in different areas. After working for a period of time, the movable ring 115 drives the light guide 111 to rotate, and the movable ring 115 moves from the first position to the second position. At this time, the lamp 11 is tilted, and the inclined parallel strong light is emitted to illuminate the prism part 112. The parallel strong light is dispersed in the process of passing through the prism part 112. Since the angles of the red light and the blue light change differently when passing through the prism part 112, the tilt angle of the lamp 11 can compensate for this, so that the red light and the blue light can be emitted from the second light outlet 144 and the first light outlet 143 respectively, so that the plants facing the lamp 11 can be alternately illuminated by the red light and the blue light, and the irradiated object is always the plant, thereby avoiding energy waste.

[0029] As another embodiment further provided by the present invention, an annular groove 117 for guiding the movement of the light guide 111 and a V-groove 118 connected to the annular groove 117 are provided inside the mounting shell 1.

[0031] Furthermore, when promoting plant growth, the movable ring 115 moves with the light guide 111, and the first tenon 116 on the connecting rod 114 moves along the annular groove 117, and the relative positions of the movable ring 115 and the light guide 111 remain unchanged; when the staff needs to observe the growth status of the plants, the movable ring 115 moves to the first position, and during the movement, the first tenon 116 enters the V-groove 118 and is pushed by the V-groove 118, and the light guide 111 moves relative to the movable ring 115, so that the reflecting part 113 moves to the bottom of the lamp 11, so that the reflecting part 113 reflects the light emitted by the lamp 11.

[0032] As another embodiment further provided by the present invention, a driving disk 12 is rotatably disposed in the mounting shell 1 , and the driving disk 12 rotates to move the light guide 111 along the annular groove 117 or the V-groove 118 .

A transverse groove 132 at the end and a vertical groove 134 of the oblique groove 133, a slope for guiding the third tenon 124 is arranged at the connection between the oblique groove 133 and the vertical groove 134, a first blocking piece 135 is arranged at the connection between the first end of the transverse groove 132 and the oblique groove 133, a second blocking piece 136 is arranged at the connection between the second end of the transverse groove 132 and the next oblique groove 133, and a torsion spring is arranged between the first blocking piece 135 and the slide plate 13, and between the second blocking piece 136 and the slide plate 13.

[0037] The mounting shell 1 is internally provided with a driving ring 141 for driving the movable ring 115 to move, and the driving ring 141 is provided with a plurality of paddles 142 extending into the movable ring 115, and the bottom of the movable ring 115 is provided with grooves corresponding to the paddles 142 one by one, a torsion spring is provided between the driving ring 141 and the mounting shell 1, and a fifth cable 148 is provided between the driving ring 141 and the slide 13, and a movable block 126 facing the slide 13 is slidably provided in the mounting shell 1, and a spring is provided between the movable block 126 and the mounting shell 1, and the movable A first pull cable 128 is arranged between the block 126 and the locking block 127, a second pull cable 129 is arranged between the locking block 127 and the rotating shaft of the lamp 11, a torsion spring is arranged between the rotating shaft of the lamp 11 and the mounting shell 1, a spring is arranged between the locking block 127 and the mounting shell 1, and a first locking hole 145 corresponding to the first position and a second locking hole 146 corresponding to the second position that are adapted to the locking block 127 are symmetrically opened on the movable ring 115, the depth of the second locking hole 146 is greater than the depth of the first locking hole 145, and the sliding rod 123 is specifically a self-elastic telescopic rod.

[0038] Furthermore, when promoting plant growth, the motor output torque drives the driving disk 12 to rotate, and the second tenon block 121 on the driving disk 12 rotates with the driving disk 12 and moves along the movable frame 122, pushing the movable frame 122, the sliding rod 123 and the third tenon block 124 to reciprocate in the horizontal direction. When the third tenon block 124 moves in the direction away from the driving disk 12, the third tenon block 124 moves along the inclined groove 133 and pushes the slide plate 13 to move in the direction close to the movable block 126. The spring between the slide plate 13 and the mounting shell 1 is stretched, and the slide plate 13 drives the driving ring 141 to rotate relative to the mounting shell 1 through the fifth cable 148. The paddle 142 is deformed to leave the groove on the movable ring 115 and gradually faces and inserts into the next groove. During the movement, the third tenon block 124 pushes the first blocking piece 135 to move, and the first blocking piece 135 makes way for the movement of the third tenon block 124, and separates from the third tenon block 124 when it enters the transverse groove 132. The first blocking piece 135 is reset under the action of the torsion spring to seal the inclined groove 133, and then the third tenon block 124 moves in the direction close to the driving disk 12, and the third tenon block 124 moves along the transverse groove 132. During this process, the sliding rod 123 pushes the second blocking piece 136, and the second blocking piece 136 makes way for the movement of the third tenon block 124, and moves to the connection between the transverse groove 132 and the next inclined groove 133, and the second blocking piece 136 is separated from the third tenon block 124 and reset under the action of the torsion spring to seal the transverse groove 132.

[0039] After the slide plate 13 repeatedly moves, the slide bar 123 pushes the movable block 126, and the movable block 126 drives the locking block 127 to move relative to the movable ring 115 through the first cable 128, so that the movable ring 115 is unlocked, and the third tenon block 124 moves to the connection between the inclined groove 133 and the vertical groove 134, and the third tenon block 124 enters the vertical groove 134 along the slope at the connection between the inclined groove 133 and the vertical groove 134, the slide bar 123 is stretched, and the slide plate 13 is pulled by the spring to move away from the movable block 126, and the torsion spring between the driving ring 141 and the mounting shell 1 releases the accumulated elastic potential energy to drive the driving ring 141 to rotate, and the driving ring 141 drives the movable ring 115 to rotate through the paddle 142, and the movable ring 115 rotates 180° to move from the first position to the second position or from the second position to the first position, and the locking block 127 is reinserted into the movable ring 115 under the push of the spring to lock the movable ring 115.

[0040] When the locking block 127 is inserted into the shallower first locking hole 145 on the movable ring 115, the second cable 129 between the locking block 127 and the rotating shaft of the lamp 11 is taut but cannot drive the lamp 11 to rotate relative to the mounting shell 1; when the locking block 127 is inserted into the deeper second locking hole 146 on the movable ring 115, the moving path of the locking block 127 is longer, which drives the second cable 129 to move farther and drives the lamp 11 to rotate relative to the mounting shell 1 through the second cable 129.

[0041] As another embodiment further provided by the present invention, a stopper 119 is slidably provided on the mounting shell 1 at the connection between the annular groove 117 and the V-groove 118 , and the driving disk 12 rotates in the opposite direction to allow the stopper 119 to block the annular groove 117 .
