The LED lamp holder 300 and the side plate 104 are made of a material with a certain hardness and good heat dissipation, such as an aluminum alloy, and the cover plate 200 is made of a material with good light transmittance and a linear expansion coefficient far larger than that of the cavity 100, such as organic glass.

The cover plate 200 is provided with a stabilizing part 202, the stabilizing part 202 is formed by extending a certain distance from the contact part of the cover plate 200 and the side plate 104 to the inside of the cavity 100, and the tail end of the stabilizing part 202 is provided with a buckle 201; be provided with joint spout 106 on the curb plate 104, joint spout 106 and buckle 201 joint cooperation, and buckle 201 can slide along joint spout 106.

Two ends of the LED lamp holder 300 are respectively provided with a dust screen 405, and the dust screens 405 respectively abut against the side plates 104 and the cover plate 200 to prevent dust and bugs from entering; the two ends of the LED socket 300 are respectively provided with a sealing ring 406, the sealing rings 406 are respectively in sealing fit with the side plate 104 and the cover plate 200, and when the elastic member 407 abuts against the two ends of the LED socket 300, the sealing rings 406 are in sealing fit with the elastic member 407. The elastic member 407 is made of a material that can be deformed and reduced within a certain range, such as deformable elastic metal stainless steel; the elastic member 407 and the seal ring 406 are tightly attached to each other by the elastic force of the elastic member 407, and the internal space of the chamber 100 is closed.

The cover plate 200 is made of a material with a large linear expansion coefficient, for example, the linear expansion coefficient of organic glass is 6-9 times that of aluminum alloy, after the LED strip lamp works for a long time, considerable heat is accumulated in the cavity 100 and the inner space, so that the temperature of the cavity 100 and the cover plate 200 is increased, and the linear expansion coefficient of the cover plate 200 is far greater than that of the side plate 104, so that the cover plate 200 expands, because the cavity 100 is in a strip shape, the expansion of the cover plate 200 in the strip shape is more accumulated, that is, in the strip shape, the cover plate 200 is lengthened, so that the elastic member 407 can be propped against and separated from the sealing ring 406, a circulation gap 401 is formed between the LED lamp holder 300 and the elastic member 407, so that the air inside the cavity 100 is communicated with the outside air, the hot air in the cavity 100 can be ejected outwards under the action of air pressure, when the hot air is exhausted in a certain amount, the outside cold air can enter the cavity 100, so as to drive the air circulation in the whole cavity 100, the heat dissipation of the electronic components in the cavity 100 is accelerated, thereby reducing the temperature of the whole LED strip lamp, and prolonging the service life of the LED strip lamp.

As shown in fig. 1, a heat dissipating fin 107 is further disposed on the side plate 104 of the chamber 100, and the heat dissipating fin 107 is fixedly connected to an outer side of the side plate 104 for dissipating heat of the chamber 100. When the temperature of the LED line lamp is not high and only generates a little heat, the heat of the electronic element in the cavity 100 can be dissipated through the heat dissipating fins 107 outside the cavity 100, and at this time, the cover plate 200 is not high in temperature and does not generate large deformation and cannot eject out the elastic component 407. The elastic member 407 and the sealing ring 406 are tightly attached to each other under the elastic force of the elastic member 407, so that the inner space of the cavity 100 is closed, and the waterproof capability of the LED strip lamp can be maintained in the closed state.

As shown in fig. 7, one end of the LED lamp socket 300 is further provided with a power plug 304, the other end of the LED lamp socket 300 is provided with a power socket 305, the power plug 304 is electrically connected to the power socket 305 and the LED lamp socket 300, the power plug 304 and the power socket 305 are respectively and fixedly connected to two ends of the cavity 100, when a plurality of LED line lamps need to be connected, the power plug 304 of one LED line lamp can be inserted into the power socket 305 of another LED line lamp, so that the plurality of LED line lamps can be simultaneously turned on, and the illumination range and the brightness can be increased.

As shown in fig. 1 and 7, the LED lamp socket 300 is provided with a screw hole 108 and a bolt 110, the elastic member 407 is provided with a locking hole 408 corresponding to the screw hole 108 of the LED lamp socket 300, and the bolt 110 locks the LED lamp socket 300 and the elastic member 407 through the screw hole 108 and the locking hole 408.

As shown in fig. 5, in the second embodiment of the present invention, the two ends of the cavity 100 are respectively provided with an inwardly recessed step portion 109, and the dust screen 405 and the sealing ring 406 are disposed in the step portion 109.

As shown in fig. 6, in the third embodiment of the present invention, the two ends of the cavity 100 are provided with the fixing post 204 and the lever 203 connected to the fixing post 204, one end of the lever 203 is in contact connection with the stabilizing portion 202 of the cover plate 200, the other end of the lever 203 is in contact connection with the elastic component 407, when the stabilizing portion 202 of the cover plate 200 extends, one end of the lever 203 is pushed, and the other end of the lever 203 moves synchronously to eject the elastic component 407. The third embodiment mainly considers that the cover plate 200 may not expand to a great extent after the temperature rises, which may cause the flow gap 401 to be too small, and the air cannot be convected to reduce the temperature in time, so the lever 203 is provided to increase the ejection degree of the elastic component 407, enlarge the gap of the flow gap 401, accelerate the air convection, reduce the temperature in time, and protect the relevant elements of the LED lamp holder 300. The fixing column 204 and the lever 203 can adopt various structures, and the plurality of fixing columns 204 and the plurality of levers 203 mainly increase the distance of the cover plate 200 or the stabilizing part 202 of the cover plate 200, and the angle of the elastic part 407 which is pushed to bend after being enlarged is increased, so that the gap formed by the elastic part 407 and the cavity 100 is increased, the speed of exchanging hot air in the cavity 100 and cold air outside is increased, the heat dissipation can be accelerated, the cooling speed is increased, related elements of the LED lamp holder 300 are cooled as soon as possible, the protection effect is achieved, and the service life of the LED line lamp is prolonged.

As shown in fig. 1 to fig. 7, in use, in an initial state, the elastic member 407 and the sealing ring 406 are tightly attached to each other under the elastic force of the elastic member 407, so that the inner space of the cavity 100 is closed, and the closed state can maintain the waterproof capability of the LED strip lamp. After the LED line lamp is turned on for a long time, along with the rise of temperature, the degree of expansion deformation of the cover plate 200 also rises, namely the cover plate 200 becomes longer, then the elastic part 407 is ejected out, so that a certain gap is formed between the elastic part 407 and the cavity 100, hot air in the cavity 100 can flow out, and external cold air can flow into the cavity 100, thereby achieving the purpose of cold-heat exchange and realizing the effect of rapid heat dissipation. Meanwhile, due to the arrangement of the dustproof net 405, dust, insects and the like can be prevented from entering the cavity 100 in the air circulation process. After heat dissipation or temperature reduction, the cover plate 200 contracts and shortens, the elastic part 407 returns to an initial state under the action of self elasticity, namely, the elastic part 407 continues to cling to the sealing ring 406, the space in the cavity 100 is closed again, and the waterproof capability of the LED line lamp is maintained.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
