The power mechanism 3 is connected with the linkage mechanism 2, and the power mechanism 3 is used for driving the linkage mechanism 2.

And the clutch mechanism 4 is connected with the linkage mechanism 2, and the clutch mechanism 4 is used for supporting the linkage mechanism 2 and controlling the linkage mechanism 2 to drive the light bearing frame 1 once to complete one motion.

The power mechanism 3 drives the linkage mechanism 2 to move, and in the process, the movement of the clutch mechanism 4 can control the linkage mechanism 2 to realize that the A end of the light bearing frame 1 rotates around the circumference of the B end or the A end moves in the vertical direction relative to the B end. In other words, the light source mounted on the light bearing frame 1 can be rotated in a fixed axis manner to realize the light irradiation effect in a plurality of directions along with the control of the clutch mechanism 4, and also can be rotated to a proper angle, the light source can be moved in a pitching manner along with the light bearing frame 1 to realize the distance adjustment of the light irradiation area relative to the light source.

When the device is matched with a common street lamp for use, the device is adopted to close the common street lamp when the flow of people is low. Under the cooperation of an intelligent system and a sensor, the light irradiation range can move along with the position of a pedestrian, and because the irradiation range is smaller than that of a common street lamp, a low-power light source can be adopted, so that the electric power is saved. And due to the characteristic that the irradiation range of the street lamp moves along with the pedestrian, the spacing distance between adjacent street lamps can be increased, the number of the street lamps is reduced, and the cost is greatly reduced.

Specifically, the linkage mechanism 2 includes a lamp post 21 and a planetary gear train 22 mounted in the lamp post 21. One end of the lamp post 21 is provided with a mounting hole 211 along the axial direction.

The planetary gear train 22 includes a sun gear 221 connected to the power mechanism 3, a plurality of planetary gears 222 connected to the clutch mechanism 4 and engaged with the sun gear 221, a gear ring 223 connected to the clutch mechanism 4 and engaged with the plurality of planetary gears 222, and a carrier 224 connected to the plurality of planetary gears 222 and coaxial with the sun gear 221.

One end of the planet carrier 224, which is far away from the planet wheel 222, protrudes out of the lamp post 21 and is rotatably connected with the end B of the lamp holder 1.

When the driving mechanism drives the center wheel 221 to rotate, there are two states: one is when clutching mechanism 4 restricts the rotation of gear ring 223, and centre wheel 221 drives a plurality of planet wheels 222 and uses centre wheel 221 as the centre rotation, and the planet carrier 224 that is connected with a plurality of planet wheels 222 is kept away from the one end of planet wheel 222 and is for shaft-like and with centre wheel 221 coaxial line, because planet carrier 224 and the up end fixed connection of planet wheel 222, the planet carrier 224 keeps away from the one end of planet wheel 222 and carries out the dead axle rotation and then drives the light-bearing support 1 of being connected with it and uses the axis of centre wheel 221 as the centre rotation this moment.

In the second case, the end B of the light-receiving bracket 1 is rotatably connected to the planet carrier 224, so that the end a of the light-receiving bracket 1 can move up and down in cooperation with the second state of the clutch mechanism 4. That is, when the clutch mechanism 4 restricts the planetary gear 222 from rotating only but not around the sun gear 221, the ring gear 223 rotates; the rotation of the wheel ring drives the other part of the linkage mechanism 2 to make the A end of the light bearing frame 1 move up and down. When the A end of the light bearing frame 1 moves up and down, the B end of the light bearing frame 1 rotates. The rotation direction of the lamp holder 1 and the axis of the center wheel 221 are located on the same plane.

When the clutch mechanism 4 restricts the rotation of the planetary gear 222 around the sun gear 221, the rotation of the sun gear 221 in turn causes the planetary gear 222 to rotate and the gear ring 223 to rotate, thereby causing the sleeve 24 to ascend or descend. In the ascending and descending process of the sleeve 24, the light bearing frame 1 is jacked or falls along the sliding block 23 under the action of gravity; in this process, the slide block 23 slides in the fitting groove 11. When the end A of the lamp holder 1 rotates around the end B, the sliding block 23 is driven to slide along the circumference of the opening part of the sleeve 24. The ball 232 effectively reduces friction, so that the sliding block 23 can slide smoothly at the opening of the sleeve 24, and the stability of the device is improved.

In addition, the sleeve 24 slides up and down in the placing hole 211, and the specific structure of the sleeve can be that a plurality of vertical sliding strips are connected on the inner wall of the sleeve 24, and a plurality of sliding grooves with one open end are arranged on the outer wall of the sleeve 24; the length directions of the sliding grooves are parallel to the axis of the sleeve 24; the slide bar is slidably inserted from below the slide groove, and when the gear ring 223 rotates, the sleeve 24 moves up and down by the slide bar.

The first self-rotating ring 41 and the second self-rotating ring 42 respectively support the gear ring 223 and the planet gears 222, when the first self-rotating ring 41 is limited to rotate, the planet gears 222 are driven to rotate by the rotation of the central wheel 221, when the second self-rotating ring 42 is limited to rotate, the planet gears 222 are driven to rotate by the central wheel 221, at the moment, the planet gears 222 cannot rotate around the central wheel 221, and then the rotation of the gear ring 223 is realized.
