When the power is off, the power supply system inside the lamp body 1 is started, and the lamp body 1 plays a lighting role. At the same time, the reciprocating mechanism 5 and the steering mechanism 4 are started synchronously, driving the fan 2 to make a semicircular reciprocating rotation, and during the rotation process, the fan 2 rotates alternately to both sides in a cycle, thereby achieving multi-directional blowing of the smoke at the bottom of the lamp body 1, so that the lighting effect of the lamp body 1 is not affected.

[0028] In this embodiment, the reciprocating mechanism 5 includes a moving plate 51, and first connecting plates 54 are provided on both sides of the moving plate 51. A connecting column 56 is fixed to one end of the first connecting plate 54 facing the moving plate 51. The connecting column 56 is rotatably plugged into the side of the moving plate 51, and the end of the first connecting plate 54 facing the arc-shaped slider 32 is rotatably connected to a second connecting plate 55 through a rotating shaft. The other end of the second connecting plate 55 is rotatably installed on the top of the slider 32 through a rotating shaft. The reciprocating mechanism 5 also includes a connecting plate 511, which is fixed to the bottom of the moving plate 51, and the connecting plate 511 is fixed to the bottom of the moving plate 51. Racks 512 are fixed on both sides of the connecting plate 511, and two half gears 510 are symmetrically arranged on both sides of the connecting plate 511, and the half gears 510 are meshed and connected with the racks 512. A motor 57 is fixedly installed at the axis of the half gear 510 on one side of the connecting plate 511 inside the lamp body 1, and a driving gear 58 is fixed on the output end of the motor 57 passing through the lamp body 1. A driven gear 59 is fixed to the bottom of the half gear 510 on the other side of the connecting plate 511 through a connecting shaft, and the half gear 510 and the driven gear 59 are rotatably installed on the top of the lamp body 1 through the connecting shaft. The driving gear 58 The two ends of the moving plate 51 are fixed with plug posts 52, and a guide sleeve 53 is fixed on the top of the lamp body 1 corresponding to the path of the plug posts 52. The plug posts 52 are slidably inserted in the guide sleeve 53, and the motor 57 is turned on. The motor 57 drives the driving gear 58 to rotate, and the driving gear 58 is meshed with the driven gear 59, so that the two half gears 510 rotate synchronously and alternately mesh with the racks 512 on both sides of the connecting plate 511, thereby driving the connecting plate 511 and the moving plate 51 to move, and the plug posts 52 slide along the guide sleeve 53 to adjust the moving path of the moving plate 51. The diameter is limited to maintain the stability of its movement. Through the connection between the first connecting plate 54 and the second connecting plate 55 and the slider 32, the movable plate 51 reciprocates and the slider 32 and the fan 2 slide back and forth along the inside of the arc-shaped slide rail 3. The fan 2 makes a semi-circular reciprocating motion to change the blowing direction of the fan 2 (when the fan 2 and the connecting block rotate to the two end vertices of the arc-shaped slide rail 3, the fan 2 rotates ninety degrees, and the first connecting plate 54 and the second connecting plate 55 rotate synchronously under the action of the connecting column 56 to maintain the connectivity with the slider 32 and the fan 2, and the connecting column 56 is rotatably installed with the movable plate 51).

[0029] In this embodiment, the steering mechanism 4 includes an arc plate 42, and the arc plate 42 is located outside the arc slide rail 3. A two-way electric push rod 41 is fixedly installed on the top of the connecting frame 31, and the two extended ends of the two-way electric push rod 41 are fixedly connected to the arc plates 42 on both sides of the lamp body 1. A slide groove is opened inside the arc plate 42, and a slide plate 43 is slidably connected inside the slide groove of the arc plate 42. The side of the fan 2 is rotatably connected to the slide plate 43 through a rotating shaft. The radius of the arc plate 42 is greater than the radius of the arc slide rail 3. The two-way electric push rod 41 is opened, and the extended end of the two-way electric push rod 41 pushes the arc plate 42 to move horizontally, and at the same time Under the connection between the slide plate 43 and the fan 2, the fan 2 rotates a certain angle along the moving direction of the arc plate 42, and by controlling the reciprocating extension and contraction of the bidirectional electric push rod 41, the arc plate 42 drives the fan 2 to reciprocate along the arc slide rail 3 to change the direction of the fan 2 (when the fan 2 moves along the arc slide rail 3 driven by the reciprocating movement mechanism 5, the slide plate 43 slides along the arc plate 42 to maintain the connectivity between the fan 2 and the arc plate 42). Since the radius of the arc plate 42 is larger than the radius of the arc slide rail 3, the arc plate 42 moves to drive the fan 2 to rotate inward without colliding with the arc slide rail 3.

[0030] In this embodiment, the fan 2 and the bidirectional electric push rod 41 are electrically connected to the battery inside the lamp body 1 through wires. The lamp body 1 is composed of several parts such as a light source, a light source driver, a rectifier, an inverter, a battery pack, and a sign lamp housing. Normally, 36V is used to drive the light source for normal lighting through the light source driver, and at the same time, the battery pack is supplemented with electric energy through the rectifier. Even when the lighting is turned off after get off work, the rectifier still works in a charging state so that the battery pack is always in a full combat readiness state; when an emergency occurs and the city power suddenly stops, the inverter will automatically start the inverter circuit, convert the low-voltage electric energy of the battery pack into high-voltage electric energy, drive the light source to continue lighting, and at the same time, the power supply provides electric energy to the motor 57 and the bidirectional electric push rod 41 and turns them on.

[0031] The lamp body 1 is installed on the top of the wall, and corresponding notches are opened on both sides of the top of the wall where the lamp body 1 is installed for installing the arc-shaped slide rail 3 and the fan 2. When the power is off, the power supply system inside the lamp body 1 is started, and the lamp body 1 plays a lighting role. At the same time, the motor 57 drives the driving gear 58 to rotate, and the driving gear 58 is meshed with the driven gear 59, so that the two half gears 510 rotate synchronously and alternately mesh with the racks 512 on both sides of the connecting plate 511, thereby driving the connecting plate 511 and the moving plate 51 to move, and the plug post 52 slides along the guide sleeve 53 to limit the moving path of the moving plate 51. Through the connection between the first connecting plate 54 and the second connecting plate 55 and the slider 32, the moving plate 5 1 reciprocates, and at the same time, the slider 32 and the fan 2 reciprocate along the inside of the arc-shaped slide rail 3, and the fan 2 makes a semicircular reciprocating motion. The extended end of the bidirectional electric push rod 41 pushes the arc plate 42 to move horizontally. At the same time, under the connection between the slide plate 43 and the fan 2, the fan 2 rotates a certain angle along the moving direction of the arc plate 42. By controlling the bidirectional electric push rod 41 to reciprocate and shorten, the arc plate 42 drives the fan 2 to reciprocate along the arc-shaped slide rail 3 to both sides, changing the direction of the fan 2, and during the rotation process, the fan 2 rotates alternately to both sides in a cycle, thereby realizing multi-directional blowing of the smoke at the bottom of the lamp body 1, so that the lighting effect of the lamp body 1 is not affected.
