The interior bottom fixedly connected with of lamps and lanterns shell 1 flexible gasbag 15, the upper end fixedly connected with of flexible gasbag 15 a plurality of reflectors 14, and reflector 14 keeps away from the one end rotation connection of flexible gasbag 15 on the inner wall of lamps and lanterns shell 1, and the inside and the first bar groove 9 of flexible gasbag 15 pass through air duct 16 intercommunication. The elastic air hood 5 and the telescopic air bag 15 are both made of elastic materials.
The side wall of the lamp housing 1 is provided with a second strip-shaped groove 11 communicated with the sliding groove 6, the side wall of the lamp housing 1 is provided with an open groove 17, and the inner top of the open groove 17 is fixedly connected with an elastic tube 18. And the elastic tube 18 is made of a metal material having good heat conductivity.
And a liquid guide pipe 13 and a liquid return pipe 19 are communicated between the second strip-shaped groove 11 and the elastic tube 18, the liquid guide pipe 13 is arranged around the LED lamp body 2, a first one-way valve is arranged in the liquid guide pipe 13, and a second one-way valve is arranged in the liquid return pipe 19. And a closed loop formed by the second strip-shaped groove, the liquid guide pipe, the elastic cylinder and the liquid return pipe is filled with cooling liquid.
The first one-way valve allows the coolant to flow only from the catheter 13 to the flexible cylinder 18, and the second one-way valve allows the coolant to flow only from the flexible cylinder 18 to the return tube 19.
It is worth mentioning that the elastic tube 18 can be fully contacted with the air flowing from the outside by arranging the open slot 17, so that the heat dissipation effect of the cooling liquid absorbing heat in the elastic tube 18 is promoted.
When the device is installed specifically, the length of the lamp shell 1 can be properly increased, so that the position distance between the elastic air hood 5 and the transparent glass plate 4 is far, and a pedestrian can easily step on the elastic air hood 5 when walking near the device.
When the pedestrian is far away from the device, most of the light emitted by the LED lamp body 2 is reflected by the horizontally arranged reflector plate 14 through the transparent glass plate 4 (as shown in figure 3), so that people at far can observe the light to achieve the lighting and indicating functions.
When a pedestrian walks to a position near the device, the pedestrian can step on the elastic air hood 5 to cause the elastic air hood 5 to contract, the sliding block 7, the connecting rod 8 and the piston 10 can be pushed to move downwards under the pushing of air pressure, the closed space above the piston 10 is increased, negative pressure is generated to pump air in the telescopic air bag 15 into the first strip-shaped groove 9 through the air guide pipe 16, the telescopic air bag 15 contracts at the moment, the plurality of light reflecting plates 14 incline downwards to reflect less light (as shown in figure 4), the illumination intensity received by eyes of the pedestrian is greatly weakened, and the injury to the eyes of the pedestrian is avoided. After the pedestrian leaves, the elastic air hood 5 and the telescopic air bag 15 are reset, and the sliding block 7, the connecting rod 8 and the piston 10 are moved upwards and reset, so that the device can be recycled.
When a pedestrian steps on the elastic air hood 5 to move the sliding block 7 downwards, the cooling liquid in the second strip-shaped groove 11 is squeezed into the elastic tube 18 along the liquid guide tube 13, after the pedestrian leaves, the elastic air hood 5 and the telescopic air bag 15 reset, the sliding block 7, the connecting rod 8 and the piston 10 move upwards to reset, meanwhile, the elastic tube 18 also resets, the cooling liquid in the elastic tube 18 is reintroduced into the second strip-shaped groove 11 along the liquid return tube 19, therefore, when the pedestrian continuously walks nearby the device, the cooling liquid flows in a one-way circulation mode along the second strip-shaped groove 11, the liquid guide tube 13, the elastic tube 18, the liquid return tube 19 and the second strip-shaped groove 11, and the liquid guide tube 13 is arranged around the LED lamp body 2, so that heat generated when the LED lamp body 2 works can be rapidly dissipated when the cooling liquid flows.
Example two:
referring to fig. 5 to 6, the difference from the first embodiment is that the threaded sleeve 21 is arranged at the bottom of the second strip-shaped groove 11, the threaded sleeve 21 is fixedly connected with a plurality of turbulence blades 12, the turbulence blades 12 are existing blades with turbulence effect and can strengthen the stirring effect in the device, the threaded sleeve 21 is internally threaded with a screw rod 20, and the upper end of the screw rod 20 is fixedly connected to the lower end of the sliding block 7.
In this embodiment, when the pedestrian is in the continuous time of walking around this device, constantly step on, leave elasticity gas hood 5, make slider 7 reciprocating motion from top to bottom, thereby promote screw rod 20 upper and lower reciprocating motion with slider 7 fixed connection, make the screw sleeve 21 with screw rod 20 threaded connection make a round trip to rotate, and drive vortex blade 12 and rotate together, can stir the coolant liquid in the second bar groove 11, accelerate the heat dissipation speed of the coolant liquid after absorbing the heat in the second bar groove 11, thereby promote the whole radiating effect of this device.
