Description

Lighting device

Technical Field

The invention belongs to the field of lighting equipment, and particularly relates to a lighting device.

Background

Street lamps refer to lamps providing a road with an illumination function, and generally refer to lamps in a road illumination range in traffic illumination. Street lamps are widely used in various places requiring illumination. The bulb of street lamp mainly adopts the LED lamp, and at street lamp lighting in-process, the street lamp directly exposes in the atmosphere, need bear the heat and shine rain, and its service environment is comparatively abominable, gathers dust and sand and winged insect on the street lamp easily, therefore the street lamp mostly uses the lamp shade airtight with the LED lamp, but leads to the temperature in the lamp shade to gather like this again and rise, and then leads to the life of LED lamp to reduce greatly. Meanwhile, when a large amount of dust and sand and flying insects are gathered on the lampshade of the street lamp, the light rays can be seriously shielded; meanwhile, after dust and sand and flying insects are gathered on the lampshade, the lampshade is covered with a layer of heat insulation layer, and the temperature in the lampshade is further increased; in addition, because the distance between the lampshade and the ground is generally higher, pollutants such as dust, sand, flying insects and the like on the lampshade are inconvenient to clean.

Disclosure of Invention

The invention aims to provide a lighting device to solve the problems that in the use process of the lighting device in the prior art, due to accumulation of pollutants such as dust and sand, a lampshade is inconvenient to clean and the internal temperature is too high.

The lighting device comprises a lampshade formed by detachably connecting an upper cover body and a lower cover body; a bulb is arranged in the lampshade; the upper cover body is fixedly connected with an adjusting box, the adjusting box comprises a box body provided with an opening and an elastic air bag positioned in the box body, the elastic air bag is communicated with a vent pipe, and one end of the vent pipe, far away from the elastic air bag, is opposite to the outer wall of the lower cover body; and a reciprocating mechanism for extruding the elastic air bag is further arranged in the box body, one side of the elastic air bag is fixedly connected in the box body, and the other side of the elastic air bag is fixedly connected to one end of the reciprocating mechanism, which is in contact with the elastic air bag.

The working principle and the beneficial effects of the scheme are as follows: fixing the adjusting box on the lamp post; the opening on the box body is closed. In the using process, the elastic air bag is extruded and restored through the reciprocating motion of the reciprocating motion mechanism; the elastic air bag is in an expansion state initially, when the elastic air bag is extruded, the gas in the elastic air bag is extruded into the vent pipe and then blown to the lower cover body of the lampshade through the vent pipe; under the blowing of the air flow, dust and sand on the lower cover body are blown off, so that the condition that the dust and sand block the light of the lamp bulb and the dust and sand cause the temperature in the lower cover body to rise is avoided. Meanwhile, when the airflow blows to the lower cover body of the lampshade, the airflow can carry away part of heat of the lower cover body, and the temperature of the lower cover body is further reduced. When the squeezing action of the reciprocating mechanism on the elastic air bag is eliminated, the reciprocating mechanism pulls the elastic air bag, and the space in the elastic air bag is enlarged, so that the internal air pressure is lower than the external air pressure, and the external air enters the elastic air bag.

Further, the reciprocating mechanism comprises a rack and a gear which are meshed with each other, and one end of the rack is fixedly connected with the elastic air bag; the gear is connected with a motor for driving the gear to rotate, and the motor is connected with a controller for controlling the on-off and steering of the gear. The gear is meshed with the rack, the on-off and steering of the motor are realized through the controller, the linear reciprocating motion of the rack is further realized, and when the rack extrudes the elastic air bag, gas in the elastic air bag is discharged outwards; when the rack is far away from the elastic air bag, outside air enters the elastic air bag.

Furthermore, a plurality of air inlet channels are arranged in the wall body of the upper cover body, and one end of the vent pipe, which is far away from the elastic air bag, is communicated with the plurality of air inlet channels; the air outlet ends of the air inlet channels are aligned with the outer wall of the lower cover body. The arrangement of the air intake passage in the upper cover body contributes to simplification of the structural components on the one hand, and at the same time, the temperature of the upper cover body can be significantly reduced when the air flows through the air intake passage in the upper cover body.

Furthermore, one end of the rack is fixedly connected with a push plate, and one end, far away from the rack, of the push plate is fixedly connected with the elastic air bag. Through setting up the push pedal for reciprocating motion mechanism is bigger with elastic airbag's area of contact, makes its extrusion effect to elastic airbag better.

Furthermore, the output shaft of the motor is detachably connected with fan blades, and the fan blades are positioned outside the box body. Through setting up the flabellum, reach a timing at external wind-force, accessible flabellum drives the rotation of motor output shaft, and then drives the rack and pinion and rotate.

Furthermore, a spring is fixedly connected to the inner wall of the box body, a baffle is fixedly connected to the spring, a through flow guide hole is formed in the baffle, and one end, far away from the spring, of the baffle is opposite to one end, far away from the elastic air bag, of the rack; a drainage hole is formed in the wall body of the box body and is positioned below the flow guide hole; the discharge hole is communicated with a discharge channel, and one end of the discharge channel, which is far away from the discharge hole, is over against the outer wall of the lower cover body. When the rainwater collecting box is used, the opening on the box body is not closed, and rainwater enters the box body through the opening of the box body and is accumulated; by arranging the baffle plate, when the rack is not in contact with the baffle plate, the baffle plate shields the drainage hole, and rainwater can be normally accumulated in the box body; when the rack contacts the baffle and pushes the baffle to move towards one end far away from the elastic air bag, the flow guide hole and the drainage hole are overlapped, so that water in the box body flows to the lower cover body of the lampshade through the drainage channel. The lower cover body is cleaned under the impact of water flow, and meanwhile, a large amount of heat can be taken away by the water flow flowing through the lower cover body, so that the temperature of the lower cover body is reduced.

Furthermore, the drainage channel is positioned in the wall body of the box body and communicated with the vent pipe. The drainage channel is arranged in the wall body of the box body, so that external connecting parts can be effectively reduced, the structure of the device is simplified, and the stability is better; simultaneously, when the air flow and the air flow are synchronously blown to the lower cover body, the cleaning and cooling effects on the lower cover body are better.

Furthermore, a partition plate is arranged in the box body, a gap is reserved between the partition plate and the box body, and the partition plate is connected in the gap in a sealing and sliding manner; the baffle is positioned right below the opening on the box body. Through setting up the baffle for the box is kept apart into two regions, thereby guarantees to store in discharge orifice place region after the rainwater is collected, avoids reciprocating motion mechanism and elasticity gasbag to be drenched.

Furthermore, a filter screen and a filter layer are sequentially arranged in the box body from top to bottom, and the filter screen is detachably connected to the opening of the box body. Through setting up filter screen and filter layer for the rainwater obtains effective filtration when entering into the box, and then guarantees the cleanness of the rainwater of the flow direction under cover body in the box.
