Description

Technical Field

[0001] This invention relates to an explosion-proof lamp, and more particularly to a highly reliable explosion-proof lamp. Background Technology

[0002] Explosion-proof lights can be used in hazardous locations where large amounts of flammable gases and dust are present to prevent the flammable gases and dust in the surrounding environment from being ignited by the electric arc or sparks generated inside the light fixture.

[0003] Therefore, explosion-proof lights need to have high structural strength and sealing to prevent electric arcs or sparks generated inside the light fixture from being conducted to the outside. However, the structural strength of existing explosion-proof lights is insufficient, so their safety still needs to be improved.

[0004] In addition, due to the lack of a good heat dissipation structure in existing explosion-proof lights, the efficiency of their internal light source modules is easily reduced due to high temperatures, which also reduces their service life. Summary of the Invention

[0005] According to an embodiment of the present invention, a highly reliable explosion-proof lamp is provided, comprising a main housing, a light source module, an upper cover, a lower cover, a lampshade, and a structural reinforcing ring. The light source module is disposed within the main housing. The upper cover is disposed at the top of the main housing. The lower cover has a mounting hole and is disposed at the bottom of the main housing. The lampshade is disposed within the mounting hole. The structural reinforcing ring is disposed between the lampshade and the light source module, and has a ring body and multiple protrusions, the multiple protrusions being disposed on the ring body, with a recess between any two adjacent protrusions.

[0006] In one embodiment, the plurality of protrusions includes a plurality of first protrusions and a plurality of second protrusions, which are arranged alternately.

[0007] In one embodiment, the width of the first protrusion is greater than the width of the second protrusion and the width of the recess, and the width of the second protrusion is less than or equal to the width of the recess.

[0008] In one embodiment, the main housing has an inner wall, an outer wall, and a plurality of connecting fins. The inner wall is connected to the outer wall through the plurality of connecting fins, thereby forming a plurality of heat dissipation spaces between the inner wall and the outer wall.

[0009] In one embodiment, the explosion-proof lamp further includes a first sealing ring and a second sealing ring. The top cover contacts the upper surface and inner surface of the top of the main housing. The first sealing ring is disposed between the top cover and the upper surface of the top of the main housing, and the second sealing ring is disposed between the top cover and the inner surface of the top of the main housing.

[0010] In one embodiment, the explosion-proof lamp further includes a third sealing ring and a fourth sealing ring. The lower cover contacts the lower surface and inner surface of the bottom end of the main housing. The third sealing ring is disposed between the lower cover and the inner surface of the bottom end of the main housing, and the fourth sealing ring is disposed between the lower cover and the lower surface of the bottom end of the main housing.

[0011] In one embodiment, the inner surface of the bottom end of the main housing has a first thread, and the outer surface of the lower cover has a second thread, and the main housing and the lower cover are joined together through the first thread and the second thread.

[0012] In one embodiment, the explosion-proof lamp further includes a plurality of heat dissipation fins and a heat dissipation wall. The plurality of heat dissipation fins are disposed on the outer surface of the main housing, and the heat dissipation wall surrounds the plurality of heat dissipation fins and partially covers the plurality of heat dissipation fins.

[0013] In one embodiment, the heat dissipation wall is streamlined.

[0014] In one embodiment, the lampshade is a spherical lampshade or a flat lampshade.

[0015] As described above, the highly reliable explosion-proof lamp according to embodiments of the present invention may have one or more of the following advantages:

[0016] (1) In one embodiment of the present invention, the explosion-proof lamp has a structural reinforcing ring. This structural reinforcing ring is disposed between the lampshade and the light source module of the explosion-proof lamp, and has a ring body and multiple protrusions. The multiple protrusions are disposed on the ring body, and a recess is formed between any two adjacent protrusions. The structural design of the above-mentioned structural reinforcing ring allows the external force applied to the lampshade to be evenly distributed within the structural reinforcing ring, thereby dispersing the impact force on the lampshade and preventing the lampshade from breaking due to external force. This significantly improves the structural strength of the explosion-proof lamp, thus effectively enhancing its safety.

[0017] (2) In one embodiment of the present invention, the explosion-proof lamp has a first sealing ring and a second sealing ring disposed between the upper cover and the main housing; in addition, the explosion-proof lamp also has a third sealing ring and a fourth sealing ring disposed between the lower cover and the main housing. The above-mentioned multi-layer sealing structure effectively improves the sealing performance of the explosion-proof lamp, thereby further enhancing the safety of the explosion-proof lamp.

[0018] (3) In one embodiment of the present invention, the main housing of the explosion-proof lamp has an inner wall, an outer wall, and multiple connecting fins. The inner wall is connected to the outer wall through the multiple connecting fins, thereby forming multiple heat dissipation spaces between the inner wall and the outer wall. The above-mentioned structural design greatly improves the heat dissipation effect of the explosion-proof lamp, ensuring that the performance of the light source module of the explosion-proof lamp is not affected by high temperature, and also improves its service life.

[0019] (4) In one embodiment of the present invention, the explosion-proof lamp has multiple heat dissipation fins and a streamlined heat dissipation wall. The multiple heat dissipation fins are disposed on the outer surface of the main housing, and the heat dissipation wall surrounds and partially covers the multiple heat dissipation fins. The above-mentioned heat dissipation structure design can effectively generate an air pressure difference in the space surrounding the explosion-proof lamp to promote airflow and further improve the heat dissipation effect of the explosion-proof lamp.

[0020] (5) In one embodiment of the present invention, the main housing of the explosion-proof lamp has a hook, and the user can hang the main housing directly on the top cover through the hook to directly carry out the installation of the explosion-proof lamp, or to repair and maintain the explosion-proof lamp, so it is more convenient to use.

[0021] (6) In one embodiment of the present invention, the structural reinforcing ring of the explosion-proof lamp can be integrated not only with the spherical lampshade, but also with the planar lampshade. Furthermore, due to the small size of the structural reinforcing ring, it does not affect the luminous effect of the light source module. Therefore, the overall performance of the explosion-proof lamp can be effectively improved, better meeting the needs of practical applications. Attached Figure Description

For ease of understanding, the same components in the following embodiments are indicated by the same symbols.

[0038] Please see Figure 1 and Figure 2 The figure shows a perspective view and a cross-sectional view of a high-reliability explosion-proof lamp according to an embodiment of the present invention. As shown in the figure, the high-reliability explosion-proof lamp 1 includes a main housing 11, an upper cover 12, a lower cover 13, a light source module 14, a lampshade 15, a structural reinforcing ring 16, a support column 17, a hook 18, multiple heat dissipation fins 19, and a heat dissipation wall 20.

[0039] The main housing 11 is a hollow cylindrical shape with an upper opening and a lower opening. The inner surface of the bottom end of the main housing 11 has a first thread F1. In one embodiment, the main housing 11 may be made of metal, such as stainless steel, iron, aluminum, etc. The hook 18 is fixed to the main housing 11 via a locking fastener K.

[0040] The light source module 14 is disposed within the main housing 11. In this embodiment, the light source module 14 may be a light-emitting diode (LED) light source module, which may include components such as a lamp board and a driving circuit. In another embodiment, the light source module 14 may also be other existing lighting modules.

[0041] The support column 17 can be fixed to the wall, and the upper cover 12 is fixed to the support column 17. The upper cover 12 is disposed at the top of the main housing 11 and covers the upper opening. The explosion-proof lamp 1 may also include a first sealing ring S1 and a second sealing ring S2. The upper cover 12 contacts the upper surface and inner surface of the top of the main housing 11. The first sealing ring S1 is disposed between the upper cover 12 and the upper surface of the top of the main housing 11, and the second sealing ring S2 is disposed between the upper cover 12 and the inner surface of the top of the main housing 11. The first sealing ring S1 adopts a compression seal, while the second sealing ring S2 adopts an interference seal. In one embodiment, the upper cover 12 may be made of metal, such as stainless steel, iron, aluminum, etc.

[0042] The lower cover 13 is disposed at the bottom end of the main housing 11 and covers the lower opening. The outer surface of the lower cover 13 has a second thread F2, and the main housing 11 and the lower cover 13 are connected to each other through the first thread F1 and the second thread F2. Sealing grease can also be added between the first thread F1 and the second thread F2. The lower cover 13 has a mounting hole H. The explosion-proof lamp 1 may also include a third sealing ring S3 and a fourth sealing ring S4. The lower cover 13 contacts the lower surface and inner surface of the bottom end of the main housing 11. The third sealing ring S3 is disposed between the lower cover 13 and the inner surface of the bottom end of the main housing 11 (between the first thread F1 and the second thread F2), and the fourth sealing ring S4 is disposed between the lower cover 13 and the lower surface of the bottom end of the main housing 11. The fourth sealing ring S4 is a compression seal, while the third sealing ring S3 is an interference seal. In one embodiment, the lower cover 13 may be made of metal, such as stainless steel, iron, aluminum, copper, etc.

[0043] The first sealing ring S1, the second sealing ring S2, the third sealing ring S3, the fourth sealing ring S4, the first thread F1, and the second thread F2 form a multi-layer sealing structure, which integrates compression sealing and interference sealing, effectively improving the sealing performance of the explosion-proof lamp 1 and further enhancing the safety of the explosion-proof lamp 1.

[0044] The lampshade 15 is disposed in the mounting hole H. In this embodiment, the lampshade 15 may be a spherical lampshade. The lampshade 15 and the lower cover 13 may be bonded together with an adhesive AG (such as resin glue) to improve their structural stability. In another embodiment, the lampshade 15 may also be a planar lampshade. The lampshade 15 may be made of transparent or translucent material.

[0045] A structural reinforcing ring 16 is disposed between the lampshade 15 and the light source module 14. The outer surface of the structural reinforcing ring 16 has threads, and the lower cover 13 also has a corresponding structure, so that the structural reinforcing ring 16 and the lower cover 13 can be fixed to each other. The external force applied to the lampshade 15 can be evenly distributed on the structural reinforcing ring 16 to disperse the impact force on the lampshade 15. In one embodiment, the structural reinforcing ring 16 may be made of plastic or metal.

[0046] The aforementioned plurality of heat dissipation fins 19 are equally spaced on the outer surface of the main housing 11. In another embodiment, the aforementioned plurality of heat dissipation fins 19 may also be equally spaced on the outer surface of the main housing 11. The heat dissipation wall 20 surrounds the aforementioned plurality of heat dissipation fins 19 and partially covers the aforementioned plurality of heat dissipation fins 19. The aforementioned plurality of heat dissipation fins 19 and the heat dissipation wall 20 may be made of metal, such as stainless steel, iron, aluminum, copper, etc.

[0047] The heat dissipation wall 22 includes two wide portions WP and two narrow portions NP connected to each other. Each narrow portion NP is disposed between the two wide portions WP, and each wide portion WP is also disposed between the two narrow portions NP. Each wide portion WP gradually narrows towards the narrow portion NP on one side (as shown by arrow A1 in the figure) and also gradually narrows towards the narrow portion NP on the other side (as shown by arrow A2 in the figure). Each narrow portion NP gradually widens towards the wide portion WP on one side (as shown by arrow A3 in the figure) and also gradually widens towards the wide portion WP on the other side (as shown by arrow A4 in the figure). Thus, the heat dissipation wall 20 can be streamlined. The above-described heat dissipation structure design can effectively generate an air pressure difference in the space surrounding the explosion-proof lamp 1, thereby promoting airflow in the space surrounding the explosion-proof lamp 1 and enhancing the heat dissipation effect of the explosion-proof lamp 1. The number of wide portions WP and narrow portions NP can be adjusted according to actual needs, and the structure of the explosion-proof lamp 1 is not limited to this embodiment.

[0048] Of course, this embodiment is only for illustrative purposes and is not intended to limit the scope of the invention. Equivalent modifications or alterations made to the explosion-proof lamp 1 according to this embodiment should still be included within the patent scope of the invention.

[0049] Please see Figure 3 This is a top view of the main housing of a high-reliability explosion-proof lamp according to an embodiment of the present invention. As shown, the main housing 11 has an inner wall 111, an outer wall 112, and multiple connecting fins 113. The inner wall 111 is connected to the outer wall 112 through the multiple connecting fins 113, forming multiple heat dissipation spaces DS between the inner wall 111 and the outer wall 112. The multiple connecting fins 113 are equally spaced between the inner wall 111 and the outer wall 112. In another embodiment, the multiple connecting fins 113 may also be unequally spaced between the inner wall 111 and the outer wall 112. The above structural design significantly increases the internal heat dissipation area of ​​the explosion-proof lamp 1, thus greatly improving its heat dissipation effect. Therefore, the efficiency of the light source module 14 of the explosion-proof lamp 1 will not be affected by high temperature, and its service life is also improved.

[0050] Of course, this embodiment is only for illustrative purposes and is not intended to limit the scope of the invention. Equivalent modifications or alterations made to the explosion-proof lamp 1 according to this embodiment should still be included within the patent scope of the invention.

[0051] Please see Figure 4 and Figure 5 This is a top view of the structural reinforcing ring of a high-reliability explosion-proof lamp according to an embodiment of the present invention, and a schematic diagram showing the relative positions of the structural reinforcing ring, the lower cover, and the lamp cover. The structural reinforcing ring 16 is disposed inside the main housing 11 and is located between the lamp cover 15 and the light source module 14.

[0052] The structural reinforcing ring 16 has a ring body 161 and a plurality of protrusions. The ring body 161 has a plurality of grooves G, so that the user can rotate the ring body 161 using a fixture corresponding to the plurality of grooves G to fix the structural reinforcing ring 16 and the lower cover 13 to each other. The plurality of protrusions include a plurality of first protrusions 162A and a plurality of second protrusions 162B, which are arranged alternately. There is a recess R between any two adjacent first protrusions 162A and second protrusions 162B. The width of the first protrusion 162A is greater than the width of the second protrusion 162B and the width of the recess R, while the width of the second protrusion 162B is less than or equal to the width of the recess R.

[0053] The width of the first protrusion 162A is greater than the width of the second protrusion 162B and the width of the recess R, thereby increasing the structural strength of the structural reinforcing ring 16. In addition, the structural design of the structural reinforcing ring 16 can prevent the structural strength of the structural reinforcing ring 16 from being affected by the volume change of the adhesive AG between the lampshade 15 and the lower cover 13 (due to thermal expansion and contraction), thereby enhancing the structural stability of the structural reinforcing ring 16.

[0054] As described above, the explosion-proof lamp 1 has a structural reinforcing ring 16, which is disposed between the lamp cover 15 and the light source module 14. The ring has a ring body 161 and multiple protrusions (including multiple first protrusions 162A and multiple second protrusions 162B). These protrusions are disposed on the ring body 161, and a recess R is formed between any two adjacent protrusions. The structural design of the reinforcing ring 16 ensures that the external force applied to the lamp cover 15 is evenly distributed within the reinforcing ring 16, thus dispersing the impact force on the lamp cover 15 and preventing it from breaking due to external force. This significantly improves the structural strength of the explosion-proof lamp 1, thereby effectively enhancing its safety.

[0055] Of course, this embodiment is only for illustrative purposes and is not intended to limit the scope of the invention. Equivalent modifications or alterations made to the explosion-proof lamp 1 according to this embodiment should still be included within the patent scope of the invention.

[0056] Please see Figure 6 and Figure 7 This is a schematic diagram illustrating the combination of the lower cover and lampshade of a high-reliability explosion-proof lamp according to one embodiment of the present invention, and a schematic diagram illustrating the combination of the lower cover and lampshade of a high-reliability explosion-proof lamp according to another embodiment of the present invention. Figure 6 As shown, the lampshade 15 can be a spherical lampshade. The lampshade 15 and the lower cover 13 can be bonded together with an adhesive AG (such as resin glue) to improve their structural stability.

[0057] like Figure 7 As shown, the lampshade 15 can also be a flat lampshade. The lampshade 15 and the lower cover 13 can be bonded together with an adhesive AG (such as resin glue) to improve their structural stability.

[0058] Structural reinforcing ring 16 is applicable Figure 6 The spherical lampshade can also be used Figure 7 The lampshade 15 is a flat lampshade. The size, material, and thickness of the lampshade 15 can be varied according to actual needs. The structural reinforcing rings 16 can disperse the impact force on the lampshade 15 to improve the structural strength of the explosion-proof lamp 1.

[0059] Of course, this embodiment is only for illustrative purposes and is not intended to limit the scope of the invention. Equivalent modifications or alterations made to the explosion-proof lamp 1 according to this embodiment should still be included within the patent scope of the invention.

[0060] It is worth mentioning that the existing explosion-proof lamps have insufficient structural strength, thus their safety needs to be improved. Furthermore, due to the lack of a good heat dissipation structure, the efficiency of the internal light source module is easily reduced by high temperatures, which also shortens its lifespan. Conversely, according to an embodiment of the present invention, the explosion-proof lamp has a structural reinforcing ring. This reinforcing ring is disposed between the lamp cover and the light source module, and has a ring body and multiple protrusions. The multiple protrusions are disposed on the ring body, and there is a recess between any two adjacent protrusions. The structural design of the reinforcing ring ensures that the external force applied to the lamp cover is evenly distributed within the reinforcing ring, thus dispersing the impact force on the lamp cover and preventing it from breaking due to external forces. This significantly improves the structural strength of the explosion-proof lamp, thereby effectively enhancing its safety.

[0061] According to an embodiment of the present invention, the explosion-proof lamp has a first sealing ring and a second sealing ring disposed between the upper cover and the main housing; furthermore, the explosion-proof lamp also has a third sealing ring and a fourth sealing ring disposed between the lower cover and the main housing. The aforementioned multi-layer sealing structure effectively improves the sealing performance of the explosion-proof lamp, further enhancing its safety.

[0062] Furthermore, according to an embodiment of the present invention, the main housing of the explosion-proof lamp has an inner wall, an outer wall, and multiple connecting fins. The inner wall is connected to the outer wall through the multiple connecting fins, thereby forming multiple heat dissipation spaces between the inner wall and the outer wall. The above-described structural design significantly improves the heat dissipation effect of the explosion-proof lamp, ensuring that the performance of the light source module of the explosion-proof lamp is not affected by high temperatures, and also extending its service life.

[0063] Furthermore, according to an embodiment of the present invention, the explosion-proof lamp has multiple heat dissipation fins and a streamlined heat dissipation wall. The multiple heat dissipation fins are disposed on the outer surface of the main housing, and the heat dissipation wall surrounds and partially covers the multiple heat dissipation fins. The above-described heat dissipation structure design can effectively generate an air pressure difference in the space surrounding the explosion-proof lamp to promote airflow and further improve the heat dissipation effect of the explosion-proof lamp.

[0064] Furthermore, according to an embodiment of the present invention, the main housing of the explosion-proof lamp has a hook, which allows the user to directly hang the main housing on the top cover for direct installation of the explosion-proof lamp, or for maintenance and repair of the explosion-proof lamp, thus making it more convenient to use.

[0065] Furthermore, according to embodiments of the present invention, the structural reinforcing ring of the explosion-proof lamp can be integrated not only with the spherical lampshade but also with the planar lampshade. Moreover, due to the small size of the structural reinforcing ring, it does not affect the luminous effect of the light source module. Therefore, the overall performance of the explosion-proof lamp can be effectively improved, better meeting the needs of practical applications. As can be seen from the above, the explosion-proof lamp according to embodiments of the present invention can indeed achieve excellent technical results.

[0066] Please see Figure 8 and Figure 9 This is a perspective view of a hook for a high-reliability explosion-proof lamp according to an embodiment of the present invention, and a schematic diagram showing the relative positions of the hook, the main housing, and the top cover. As shown in the figure, the hook 18 can be fixed to the main housing 11 by means of a fastener K, and the top cover 12 has a fixing part 121.

[0067] Please see Figure 10 , Figure 11 and Figure 12 These are first, second, and third schematic diagrams illustrating the usage state of a high-reliability explosion-proof lamp according to an embodiment of the present invention. Figure 10 As shown, when a user wants to install the explosion-proof light 1, the user can fix the support column 17 to the wall and fix the top cover 12 to the support column 17.

[0068] like Figure 11 As shown, the user can hang the main housing 11 directly on the fixing part 121 of the upper cover 12 via the hook 18.

[0069] like Figure 12 As shown, when the main housing 11 is hung on the fixing part 121 of the upper cover 12 via the hook 18, the user can perform the installation operation of the light source module 14.

[0070] Similarly, when a user wants to repair or maintain the explosion-proof lamp 1, the user can open the top cover 12, detach the main housing 11 from the top cover 12, and hang the main housing 11 directly on the top cover 12 via the hook 18. Then, the user can directly repair and maintain the explosion-proof lamp 1, making it more convenient to use.

[0071] Of course, this embodiment is only for illustrative purposes and is not intended to limit the scope of the invention. Equivalent modifications or alterations made to the explosion-proof lamp 1 according to this embodiment should still be included within the patent scope of the invention.

[0072] In summary, according to embodiments of the present invention, the explosion-proof lamp has a structural reinforcing ring. This structural reinforcing ring is disposed between the lamp cover and the light source module of the explosion-proof lamp, and has a ring body and multiple protrusions. The multiple protrusions are disposed on the ring body, and there is a recess between any two adjacent protrusions. The structural design of the above-mentioned structural reinforcing ring allows the external force applied to the lamp cover to be evenly distributed on the structural reinforcing ring, thereby dispersing the impact force on the lamp cover and preventing the lamp cover from breaking due to external force. This significantly improves the structural strength of the explosion-proof lamp, thus effectively enhancing the safety of the explosion-proof lamp.

[0073] According to an embodiment of the present invention, the explosion-proof lamp has a first sealing ring and a second sealing ring disposed between the upper cover and the main housing; furthermore, the explosion-proof lamp also has a third sealing ring and a fourth sealing ring disposed between the lower cover and the main housing.

[0074] Furthermore, according to an embodiment of the present invention, the main housing of the explosion-proof lamp has an inner wall, an outer wall, and multiple connecting fins. The inner wall is connected to the outer wall through the multiple connecting fins, thereby forming multiple heat dissipation spaces between the inner wall and the outer wall. The above-described structural design significantly improves the heat dissipation effect of the explosion-proof lamp, ensuring that the performance of the light source module of the explosion-proof lamp is not affected by high temperatures, and also extending its service life.

[0075] Furthermore, according to an embodiment of the present invention, the explosion-proof lamp has multiple heat dissipation fins and a streamlined heat dissipation wall. The multiple heat dissipation fins are disposed on the outer surface of the main housing, and the heat dissipation wall surrounds and partially covers the multiple heat dissipation fins. The above-described heat dissipation structure design can effectively generate an air pressure difference in the space surrounding the explosion-proof lamp to promote airflow and further improve the heat dissipation effect of the explosion-proof lamp.

[0076] Furthermore, according to an embodiment of the present invention, the main housing of the explosion-proof lamp has a hook, which allows the user to directly hang the main housing on the top cover for direct installation of the explosion-proof lamp, or for maintenance and repair of the explosion-proof lamp, thus making it more convenient to use.

[0077] Furthermore, according to embodiments of the present invention, the structural reinforcing ring of the explosion-proof lamp can be integrated not only with the spherical lampshade but also with the planar lampshade. Moreover, due to the small size of the structural reinforcing ring, it does not affect the luminous effect of the light source module. Therefore, the overall performance of the explosion-proof lamp can be effectively improved, better meeting the needs of practical applications.

Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this invention, or equivalent structural or procedural transformations made using the description and drawings of this invention, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this invention.
