The present application is described in further detail below with reference to figures 1-6.

The embodiment of the application discloses an LED lamp. Referring to fig. 1, the LED lamp includes a housing 1, and the housing 1 includes a main case 101 and an end cap 102, and edges of the main case 101 and the end cap 102 are connected to each other. The main casing 101 has a first through hole 2 formed at a corner thereof. The main casing 101 is transparent so that the light in the housing 1 can pass through the main casing 101.

Referring to fig. 2, a second through hole 3 is formed in a surface of the end cover 102 opposite to the first through hole 2. The second through hole 3 and the first through hole 2 are arranged diagonally. In the process of flowing air from the first through hole 2 into the second through hole 3, the air flows through the LED panel in the housing 1 as much as possible (see fig. 3).

Referring to fig. 3, a socket 8 is opened at one end of the main case 101 for inserting the LED panel therein. The end cap 102 closes the socket 8, thereby forming a closed cavity. The edge of the socket 8 is provided with a convex ring 9, and the edge of the end cover 102 is provided with a ring groove 10 matched with the convex ring 9. When the inserting opening 8 is connected with the end cover 102, the convex ring 9 is in inserting fit with the annular groove 10, and then the connecting seam between the end cover 102 and the inserting opening 8 is adhered by glue. The LED panel comprises a panel body 11 and LED lamp beads 12, wherein the LED lamp beads 12 are embedded in the front of the panel body 11. The end portion of the inner wall of the main casing 101 is provided with a first locking groove 15, in this embodiment, the first locking groove 15 is formed by two sheet bodies at an interval, and in some embodiments, the first locking groove 15 may also be a groove recessed toward the inner wall of the main casing 101. The end portion of the inner wall of the end cap 102 is provided with a second locking groove 16, in this embodiment, the second locking groove 16 is formed by two sheets at intervals, and in some embodiments, the second locking groove 16 may also be a groove recessed toward the inner wall of the end cap 102. A first vent pipe 4 is communicated with the first through hole 2 in the shell 1, and a second vent pipe 5 is communicated with the second through hole 3.

Referring to fig. 4, the one side that panel body 11 and LED lamp pearl 12 carried on the back mutually, panel body 11's the back promptly is connected with the heat conductor, and the heat conductor includes dustcoat 13 and phase change material, through the glue adhesion between dustcoat 13 and the panel body 11. One side of the outer cover 13 facing the panel body 11 is a concave groove, respective cavities are formed between the outer cover 13 and the panel body 11, and the phase-change material is filled in the cavities. In the present embodiment, the phase change material may be Na2SO4 · 10H2O, CaCl2 · 6H2O, Na2HPO4 · 12H2O, or the like. The phase-change energy storage material is widely applied to medium-temperature and low-temperature phase-change energy storage, and has the advantages of wide application range, large heat conductivity coefficient, large heat fusion, large heat storage density, small phase-change volume change, low toxicity, low price and the like. After the phase-change material absorbs the heat generated by the LED lamp beads 12, the state of the material is changed, but the temperature is unchanged, the continuous temperature rise of the LED lamp beads 12 increases the temperature difference between the LED lamp beads and the phase-change material, the heat transfer efficiency is improved, so that the phase-change material absorbs heat more quickly, and the temperature rise speed of the LED lamp beads 12 is restrained.

Referring to fig. 5, a schematic structural diagram of the first tube is shown, and since the second tube has the same structure as the first tube, only the first tube is taken as an example in the present application for exemplary description. The first breather pipe 4 can be structurally divided into a first section and a second section, wherein the first section of the first breather pipe 4 is obliquely and upwards arranged from the first through hole 2 to the inner direction of the shell 1, and the second section, namely one end close to the inner part of the shell 1 is communicated with one end of the first section far away from the first through hole 2 and is upwards bent. Similarly, the second vent pipe 5 is arranged upwards from the second through hole 3 to the housing 1, and one end of the second vent pipe 5 in the housing 1 is bent upwards. This structure of the first vent pipe 4 makes the moisture and dust in the outside air enter the casing 1 upward with the antigravity, which increases the difficulty of the moisture and dust entering the casing 1. And filters 6 are provided in both the first and second breather pipes 4 and 5. Referring to fig. 6, the filter 6 includes a housing 61 and a filter element 62, wherein the filter element 62 may be bio-cotton or filter cotton. The outer shell 61 is a cylindrical hollow tubular structure, and the outer side wall of the outer shell 61 is adhered to the inner wall of the first vent pipe 4 through glue. The housing 61 is provided with air holes 7 at both ends thereof. The outside air can enter the casing 1 through the filter element 62, and the filtering effect of the filter element 62 further prevents the moisture and dust in the outside air from entering the casing 61.

Referring to fig. 5, the edge of one end of the first vent pipe 4 located in the housing 1 and the edge of one end of the second vent pipe 5 located in the housing 1 are both provided with a bimetal 14, when the temperature of the bimetal 14 is lower than the first temperature, the bimetal 14 closes the end opening of the first vent pipe 4 and the end opening of the second vent pipe 5, and when the temperature of the bimetal 14 is higher than the first temperature, the bimetal 14 deforms not to close the end opening of the first vent pipe 4 and the end opening of the second vent pipe 5. Wherein the first temperature is the temperature when the bimetallic strip 14 is just deformed to close the first vent pipe 4 and the second vent pipe 5. The bi-metallic strip 14 is a composite material composed of two or more metals or other materials having suitable properties. Because the thermal expansion coefficients of the component layers are different, when the temperature changes, the deformation of the active layer is larger than that of the passive layer, so that the whole bimetallic strip 14 bends towards one side of the passive layer, and the curvature of the composite material changes, thereby generating deformation. When the LED lamp does not work, heat dissipation is not needed, so that the temperature in the shell 1 is low, and the bimetallic strip 14 seals the end opening of the first vent pipe 4 and the end opening of the second vent pipe 5, so that the communication time of the first vent pipe 4 and the second vent pipe 5 is reduced, and the possibility of water vapor and dust entering is reduced. When the LED lamp works, the generated heat raises the temperature in the shell 1, and the bimetallic strip 14 is deformed by the temperature rise and does not close the end opening of the first vent pipe 4 and the end opening of the second vent pipe 5 any more. In order to make the bimetal 14 effectively close the end portions of the first vent pipe 4 and the second vent pipe 5, the cross section of the bimetal 14 is slightly larger than the opening aperture of the first vent pipe 4 and the second vent pipe 5. Because the bimetallic strip 14 can deform at the end edge of the first vent pipe 4 and the end edge of the second vent pipe 5, in order to fix the bimetallic strip 14 firmly with the end edge of the first vent pipe 4 and the end edge of the second vent pipe 5, a small insertion sheet protrudes from the edge of the bimetallic strip 14, is inserted into the wall thickness of the end part of the first vent pipe 4 and the end part of the second vent pipe 5, and is fixedly connected through hot melting.

The implementation principle of the LED lamp provided by the embodiment of the application is as follows: because the motor vehicle or non-motor vehicle that has the LED lamp generally can open LED lamp pearl 12 in the driving condition, consequently take first through-hole 2 as the windward side when motor vehicle or non-motor vehicle travel as the example, when LED lamp pearl 12 opens one end time, when the temperature height in the casing 1 is higher than first through-hole 2, bimetallic strip 14 deformation is opened, the air passes through first through-hole 2 from first through-hole 2 and gets into in the casing 1 through the filtration of filter 6, then flow out casing 1 through filter 6 through second through-hole 3, take away the heat that LED lamp pearl 12 produced, thereby realize the cooling of LED lamp pearl 12. And when LED lamp pearl 12 was out of work, bimetallic strip 14 closed the one end that first breather pipe 4 was located casing 1 and the one end that second breather pipe 5 was located casing 1, can further avoid external steam and dust to enter into in the casing 1.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
