The light source assembly is arranged in the light source cavity, and the heat generated by the light source assembly when working is dissipated through the lamp body, thereby improving the explosion-proof performance of the explosion-proof lamp. The power supply assembly is used to supply power to the light source assembly. Separating the power supply assembly from the light source assembly can effectively disperse the heat generated by the power supply assembly and the light source assembly when working, thereby avoiding the accumulation of heat in a limited space and further improving the overall heat dissipation efficiency of the explosion-proof lamp.

Detailed implementation manners

[0038] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific implementation examples described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0039] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0040] In the present utility model, terms such as "upper", "lower", "left", "right", "front", "rear", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe the present utility model and its embodiments, and are not used to limit that the indicated device, element or component must have a specific orientation, or be constructed and operated in a specific orientation.

[0041] Moreover, in addition to being able to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present utility model can be understood according to the specific circumstances.

[0042] In addition, terms such as "mounted", "arranged", "provided with", "connected", "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there can be internal communication between two devices, elements or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0043] Please refer to Figure 1 and Figure 2 , the first embodiment of the present utility model provides a lamp body 1, which includes a bottom cover 10, a side cover 11 and a plurality of heat dissipation fins 12. The side cover 11 surrounds the bottom cover 10 and is connected to the bottom cover 10 through a plurality of heat dissipation fins 12. A plurality of heat dissipation gaps 13 are formed between the side cover 11 and the bottom cover 10 at intervals through the plurality of heat dissipation fins 12.

[0044] It can be understood that the plurality of heat dissipation fins 12 significantly increase the heat dissipation surface area of the lamp body 1, and can improve the heat dissipation efficiency. During the lighting operation, the temperature inside the lamp body 1 will rise to form hot air. The design of the heat dissipation gaps 13 can form a chimney effect, enabling the air flow to circulate through the heat dissipation gaps 13 and being guided by the heat dissipation fins 12, strengthening the air circulation, so that the hot air generated inside the lamp body 1 can more smoothly exchange with the outside cold air, thereby accelerating the heat dissipation.

[0045] It can be understood that the heat dissipation fins 12 connecting the bottom cover 10 and the side cover 11 can be evenly arranged. The evenly arranged heat dissipation fins 12 form uniform heat dissipation gaps 13 at intervals, so that the heat inside the lamp body 1 can be more evenly and quickly transferred to the surface of the heat dissipation fins 12, preventing the phenomenon of heat accumulation and local overheating, and at the same time making the appearance of the lamp body 1 more beautiful.

[0046] It can be understood that the side cover 11 is arranged around the bottom cover 10 to further protect the components inside the lamp body 1, prevent physical damage such as impact, facilitate cleaning, make the overall design more beautiful and simple, and can also reduce glare and improve lighting comfort.

[0047] Please further combine Figure 3 A light source cavity 100 is opened inside the bottom cover 10 , one end of the heat dissipation fin 12 is connected to the inner wall of the side cover 11 , and the other end is connected to the outer side of the bottom cover 10 and extends to the side of the bottom cover 10 away from the light source cavity 100 .

[0048] It can be understood that the light source cavity 100 provided in the bottom cover 10 is used to accommodate components such as light sources. When working, a large amount of heat generated by components such as light sources will be transferred to the bottom cover 10 and the side cover 11, and the bottom cover 10 and the side cover 11 simultaneously play a role in heat dissipation. The heat dissipation fins 12 extend to the side of the bottom cover 10 away from the light source cavity 100, which can further increase the heat dissipation area and improve the heat dissipation efficiency. At the same time, the heat dissipation fins 12 play a role in guiding the flow direction of the airflow, guiding the airflow from the heat dissipation gap 13 to the side of the bottom cover 10 away from the light source cavity 100, further enhancing the heat dissipation effect of the bottom cover 10.

[0049] Furthermore, the bottom cover 10 , the side cover 11 and the plurality of heat dissipation fins 12 are integrally formed.

[0050] It can be understood that the one-piece design can eliminate the gaps and looseness at the connection between the multiple heat dissipation fins 12 and the bottom cover 10 and the side cover 11, making the structure of the entire lamp body 1 more stable, reducing the problems caused by loose connection parts, and at the same time reducing the number of parts, simplifying the manufacturing process, reducing manufacturing costs, improving production efficiency, reducing maintenance costs, and making the appearance design more neat and beautiful.

[0051] Please further combine Figure 4 , defining an end where the heat dissipation fin 12 is connected to the inner wall of the side cover 11 as a first end 120 , and a height of the first end 120 does not exceed a height of the side cover 11 .

[0052] It can be understood that this design allows the first end 120 of the heat dissipating fin 12 to be completely hidden between the side cover 11 and the bottom cover 10, simplifying the visible external structure and making the overall design of the lamp body 1 more beautiful. At the same time, the side cover 11 protects the heat dissipating fin 12, making it easier to clean and maintain it later.

[0053] Furthermore, the end of the heat dissipation fin 12 extending to the side of the bottom cover 10 away from the light source cavity 100 is defined as the second end 121, the second end 121 extends toward the center of the bottom cover 10, and the spacing between the second ends 121 of multiple heat dissipation fins 12 is not less than a preset minimum spacing.

[0054] Understandably, the second end 121 extends towards the center of the bottom cover 10, that is, the heat dissipation fins 12 are arranged in a radially outward layout with the center of the bottom cover 10 as the center. This design further strengthens the function of the heat dissipation fins 12 to guide the air flow direction, ensuring that the air flow can flow towards the central part of the bottom cover 10, realizing all-round heat dissipation of the bottom cover 10.

[0055] Understandably, if the number of the heat dissipation fins 12 is set too large, or the spacing between the heat dissipation fins 12 is too small, it will increase the air flow resistance, resulting in poor air circulation and the heat not being dissipated into the air in time, but instead reducing the heat dissipation effect. The preset minimum spacing can balance the number of the heat dissipation fins 12 and the extension length of the second end 121 of the heat dissipation fins 12, ensuring that while the heat dissipation area of the heat dissipation fins 12 is large enough, the air can smoothly flow through the gaps between the multiple heat dissipation fins 12 to obtain a better heat dissipation effect.

[0056] Understandably, in this embodiment, the extension length of the heat dissipation fins 12 is not specifically limited, and the extension lengths of the respective heat dissipation fins 12 can be the same or staggered.

[0057] Furthermore, the bottom cover 10 is provided with a wiring groove 101 communicating with the light source cavity 100.

[0058] Understandably, the wiring groove 101 is used to accommodate the wires for supplying power to the devices arranged in the light source cavity 100. The wiring groove 101 can hide the wires inside the lamp body 1, reducing the direct contact between the wires and the external environment, and reducing the risk of sparks or short circuits caused by the exposure of the wires, thereby further improving the explosion-proof performance of the lamp.

[0059] Preferably, the wiring groove 101 can extend to the middle of the light source cavity 100, more conveniently supplying power to multiple devices located inside the light source cavity 100.

[0060] Please refer to Figure 2 and Figure 4 , the lamp body 1 further includes an upper cover 14. The bottom cover 10 is provided with an annular groove 102 around the light source cavity 100, and at least a part of the upper cover 14 is arranged in the annular groove 102.

[0061] Understandably, the annular groove 102 can make the upper cover 14 cooperate with the bottom cover 10 more firmly, providing better protection for the devices arranged inside the lamp body 1, preventing combustible gases or dust from entering the inside of the lamp body 1, and reducing the risk of explosion or fire caused by reasons such as electric sparks.

[0062] Furthermore, the annular groove 102 and the upper cover 14 are provided with matching thread structures 103, and the upper cover 14 and the bottom cover 10 are detachably connected through the thread structures 103.

[0063] It can be understood that the upper cover 14 and the bottom cover 10 are detachably connected, which can simplify the assembly process and facilitate disassembly and maintenance. The threaded structure 103 can effectively isolate external harmful substances such as moisture, dust, corrosive gases, etc. from entering the interior of the lamp body 1 through a tight bite, thereby protecting internal devices and circuits from damage. At the same time, better sealing can enhance the explosion-proof performance.

[0064] It is understandable that the upper cover 14 and the bottom cover 10 can also be detachably connected in other ways, such as snap connection, pin connection, etc. In order to make the connection between the upper cover 14 and the bottom cover 10 tighter, a sealing ring can be further provided between the two.

[0065] Furthermore, the lamp body 1 further includes a transparent cover 15 disposed above the light source cavity 100 , and the transparent cover 15 is fixed between the upper cover 14 and the bottom cover 10 .

[0066] It can be understood that the transparent cover 15 has good light transmittance, which allows light to penetrate smoothly and illuminate the target area to achieve the lighting function. The transparent cover 15 is fixedly arranged between the upper cover 14 and the bottom cover 10, which can effectively isolate the internal light source from the external environment, prevent harmful substances such as dust, water vapor, and corrosive gases from entering the interior of the lamp body 1, thereby protecting the light source and circuit from damage, and further enhancing the explosion-proof performance.

[0067] It can be understood that in this embodiment, the specific method of fixing the transparent cover 15 between the upper cover 14 and the bottom cover 10 is not limited. The transparent cover 15 can be clamped between the upper cover 14 and the bottom cover 10 through a mechanical structure, or fixed between the upper cover 14 and the bottom cover 10 by gluing. A sealing ring can also be added to make the fixation of the transparent cover 15 more reliable.

[0068] It can be understood that in this embodiment, there is no specific limitation on the shapes of the bottom cover 10 and the side cover 11. Optionally, the side cover 11 is arranged around the bottom cover 10, and should be able to surround the bottom cover 10, the upper cover 14 and the transparent cover 15, that is, when viewed from the side, the bottom cover 10, the upper cover 14 and the transparent cover 15 are all hidden in the side cover 11, so that the side cover 11 plays a better protective role, making the overall shape of the lamp body 1 more concise and beautiful, convenient for cleaning and maintenance, and preventing glare.

[0069] Furthermore, the end of the side cover 11 that is away from the light emitting direction can be set to a certain curvature inward to play a better protective role and prevent dust from entering the interior of the lamp body 1 through the heat dissipation gap 13.

[0070] Please continue reading Figure 5 and Figure 6, the second embodiment of the present invention provides an explosion-proof lamp 2, which includes the above-mentioned lamp body 1, a light source assembly 20 installed inside the lamp body 1, and a power supply assembly 21 electrically connected to the light source assembly 20.

[0071] Understandably, setting the light source assembly 20 of the explosion-proof lamp 2 inside the lamp body 1 can prevent harmful substances such as dust, water vapor, and corrosive gases from damaging the light source assembly 20, and the lamp body 1 can also prevent physical damage such as impact. At the same time, the excellent sealing and heat dissipation performance of the lamp body 1 can ensure that the explosion-proof lamp 2 has good explosion-proof performance.

[0072] Please further combine Figure 7 , the light source assembly 20 includes a substrate 200, a light source 201 and a lens 202 arranged on the substrate 200; the power supply assembly 21 includes a housing 210, a power supply 211 and power terminals arranged inside the housing 210, and a wire 214 connected to the power supply 211; the light source assembly 20 is electrically connected to the power supply assembly 21 through the wire 214.

[0073] Understandably, the light source 201 arranged on the substrate 200 can specifically be an LED lamp bead, and multiple light sources 201 can be arranged, evenly distributed on the substrate 200. The arrangement of the light sources 201 on the substrate 200 can also adopt non-uniform distribution. For example, in the edge or outer area of the substrate 200, the arrangement density of the light sources 201 is higher than that in the center or inner area of the substrate 200. This design can effectively compensate for the light attenuation caused by distance or occlusion, so as to achieve a more uniform light distribution on the entire surface of the substrate 200.

[0074] The lens 202 is arranged on one side of the light-emitting direction of the light source 201. The lens 202 is used to change the propagation direction of the light of the light source 201, improve the utilization rate of the light, and make the lighting efficiency of the explosion-proof lamp 2 higher.

[0075] Understandably, in this embodiment, the shape of the lens 202 is not specifically limited, and different lenses 202 can be selected according to different lighting requirements.

[0076] Preferably, the lens 202 is a threaded lens, and the threaded lens has continuous grooves or protrusions, which can more effectively utilize the light, can reduce the power requirement of the light source 201, and reduce the operating cost.

[0077] Optionally, the substrate 200 of the light source assembly 20 can be an aluminum substrate, and the aluminum substrate has good thermal conductivity and can quickly dissipate heat.

[0078] Optionally, the lens 202 can be made of materials such as glass and resin, preferably PC material. The lens 202 made of PC material has significant advantages such as strong impact resistance, high heat resistance, high transparency, light focusing and concentration, enhanced coating performance, and long service life.

[0079] It can be understood that there are two power terminals, namely, input terminal 212 and output terminal 213, and both input terminal 212 and output terminal 213 are electrically connected to power supply 211. Input terminal 212 is also connected to an external wire for connecting to an external power source to realize operations such as charging or powering power supply 211, and also ensures that the entire power supply component 21 can continuously and reliably obtain the required power input. Power supply 211 is responsible for storing, converting or distributing electrical energy. It receives electrical energy from input terminal 212 and processes it as needed to provide appropriate electrical energy output for light source component 20. Output terminal 213 is connected to wire 214, and is responsible for outputting the electrical energy processed by power supply 211 to light source component 20.

[0080] Furthermore, a light source cavity 100 and a wiring groove 101 connected to the light source cavity 100 are opened on the inner side of the bottom cover 10, the light source assembly 20 is arranged in the light source cavity 100, the power supply assembly 21 is arranged on the side of the bottom cover 10 away from the light source cavity 100, and the wire 214 is electrically connected to the substrate 200 through the wiring groove 101.

[0081] It can be understood that the wire 214 is electrically connected to the substrate 200 through the wiring slot 101 to deliver power to the light source assembly 20. The housing of the power supply assembly 21 is provided with an opening for the wire 214 to pass through. In order for the wiring slot 101 to better hide the wire 214 inside the lamp body 1, the position of the opening should be set corresponding to the entrance of the wiring slot 101, further reducing the risk of sparks or short circuits caused by the exposure of the wire 214. The output terminal 213 can be further arranged close to the opening, which can shorten the wiring length of the wire, reduce unnecessary energy loss, and improve overall reliability.

[0082] It can be understood that the power supply assembly 21 is arranged on the side of the bottom cover 10 away from the light source cavity 100, that is, the power supply assembly 21 and the light source assembly 20 are arranged separately, which can effectively disperse the heat generated by the power supply assembly 21 and the light source assembly 20 during operation, avoid the accumulation of heat in a limited space, and thus improve the overall heat dissipation efficiency of the explosion-proof lamp 2. The power supply assembly 21 and the bottom cover 10 can be connected by a connecting column, further increasing the heat dissipation space between the power supply assembly 21 and the bottom cover 10, reducing the risk of overheating of the explosion-proof lamp 2, and improving safety.

[0083] Furthermore, a plurality of heat dissipation ribs 215 are disposed on the outer side of the housing 210 .

[0084] It can be understood that the multiple heat dissipation ribs 215 increase the heat dissipation area of ​​the shell 210, which can effectively dissipate heat for devices such as the power supply 211 inside the power supply assembly 21. At the same time, the gaps between the heat dissipation ribs 215 facilitate air circulation, reduce the risk of overheating of the explosion-proof lamp 2, and improve safety.

[0085] Understandably, in this embodiment, the layout of the multiple heat dissipation ribs 215 is not specifically limited. Optionally, the heat dissipation ribs 215 are evenly distributed on the side wall of the housing 210 and on the side close to the lamp body 1. The heat dissipation ribs 215 and the heat dissipation fins 12 can jointly play a role in guiding the air flow, so that the air flow can fully flow on the surfaces of the lamp body 1 and the housing 210, taking away the heat generated by the light source assembly 20 and the power supply assembly 21.

[0086] Understandably, the housing 210 can be set into two detachable parts, which is convenient for assembly and maintenance.

[0087] Furthermore, a receiving cavity 104 is formed at the bottom of the light source cavity 100, and an inductor 203 electrically connected to the substrate 200 is arranged in the receiving cavity 104.

[0088] Understandably, the inductor 203 can detect any motion state of a human body, an object, etc. within the sensing range. When a person or an object enters the sensing area, the explosion-proof lamp 2 can automatically light up without a manual switch, improving the intelligence level of the lighting system. In an unmanned area or a specific time period, the inductor 203 can make the explosion-proof lamp 2 enter a low-power mode or a closed state, reducing unnecessary lighting, and at the same time reducing energy consumption and safety hazards such as fires.

[0089] Optionally, the inductor 203 is a microwave inductor, the substrate 200 is a microwave aluminum substrate, and the lens 202 is a microwave lens. The three cooperate to effectively improve the sensing sensitivity and sensing range of the inductor 203. The inductor 203 can also be any one of an infrared inductor, an ultrasonic inductor, an image sensor, etc., which can detect the motion state of a human body, an object, etc. within the sensing range.

[0090] Understandably, an opening can be further formed in the substrate 200 at the position corresponding to the inductor 203 to expose the inductor 203, so as not to affect the sensing effect of the inductor 203.

[0091] Understandably, the explosion-proof lamp 2 also includes all the beneficial effects of the above-mentioned lamp body 1, which will not be elaborated here.

[0092] Compared with the prior art, the lamp body and the explosion-proof lamp provided by the present utility model have the following advantages:

[0093] 1. The lamp body provided in the embodiment of the utility model includes a bottom cover, a side cover and a plurality of heat dissipation fins. The side cover is arranged around the bottom cover and connected to the bottom cover through a plurality of heat dissipation fins, so that the heat dissipation surface area is significantly increased, thereby improving the heat dissipation efficiency. The side cover is arranged around the bottom cover to protect the components inside the lamp body, which can prevent impact and facilitate cleaning, making the overall design more beautiful and simple, and can also reduce glare and improve the comfort of lighting. At the same time, a plurality of heat dissipation gaps are formed between the side cover and the bottom cover through a plurality of heat dissipation fins. When the components inside the lamp body are working, the temperature inside the lamp body will rise, forming hot air. The design of the heat dissipation gap can form a chimney effect, so that the airflow can flow through the heat dissipation gap and be guided by the heat dissipation fins, thereby strengthening the circulation of air, so that the hot air generated inside the lamp body can be more smoothly exchanged with the cold air outside, thereby accelerating the dissipation of heat.

[0094] 2. The lamp body provided in the embodiment of the utility model has a light source cavity on the inner side of the bottom cover, and the light source and other devices of the lamp are arranged in the light source cavity. One end of the heat dissipation fin is connected to the inner wall of the side cover, and the other end is connected to the outer side of the bottom cover and extends to the side of the bottom cover away from the light source cavity. This design can further increase the heat dissipation area and improve the heat dissipation efficiency. At the same time, the heat dissipation fins play a role in guiding the direction of airflow, guiding the airflow from the heat dissipation gap to the side of the bottom cover away from the light source cavity, thereby further enhancing the heat dissipation of the bottom cover.

[0095] 3. The lamp body, bottom cover, side cover and multiple heat dissipation fins provided in the embodiment of the utility model are integrally formed. This design can eliminate gaps and looseness at the connection, making the entire structure more stable and reducing problems caused by loose connection parts. At the same time, it reduces the number of parts, simplifies the manufacturing process, reduces manufacturing costs, improves production efficiency, reduces maintenance costs, and makes the appearance design neater and more beautiful.

[0096] 4. The lamp body provided in the embodiment of the utility model defines the end where the heat dissipating fins are connected to the inner wall of the side cover as the first end, and the height of the first end does not exceed the height of the side cover. This design allows the first end of the heat dissipating fin to be completely hidden between the side cover and the bottom cover, thereby simplifying the visible external structure and making the overall design more beautiful. At the same time, the side cover protects the heat dissipating fins, which is convenient for later cleaning and maintenance.

[0097] 5. The lamp body provided in the embodiment of the utility model defines the end of the heat dissipation fin extending to the side of the bottom cover away from the light source cavity as the second end, and the second end extends along the center of the bottom cover. This design further strengthens the role of the heat dissipation fin in guiding the airflow direction, ensuring that the airflow can flow to the central part of the bottom cover, and realizing all-round heat dissipation of the bottom cover. The spacing between the second ends of the plurality of heat dissipation fins is not less than the preset minimum spacing. The preset minimum spacing can balance the number of heat dissipation fins and the extension length of the second end, ensuring that the heat dissipation area of ​​the heat dissipation fins is large enough and the air can flow smoothly through the gaps between the plurality of heat dissipation fins, so as to obtain a better heat dissipation effect.

[0098] 6. The lamp body provided in the embodiment of the utility model further includes an upper cover, and the bottom cover is provided with an annular groove around the light source cavity, and the upper cover is at least partially arranged in the annular groove. The annular groove can make the upper cover more firmly cooperate with the bottom cover, better protect the internal structure of the lamp, prevent flammable gas or dust from entering the interior of the light-emitting component, and reduce the risk of explosion or fire caused by electric sparks and the like.

[0099] 7. The explosion-proof lamp provided in the embodiment of the utility model includes a lamp body, a light source assembly installed inside the lamp body, and a power supply assembly electrically connected to the light source assembly. The light source assembly is arranged in the light source cavity, and the heat generated by the light source assembly when working is dissipated through the lamp body, thereby improving the explosion-proof performance of the explosion-proof lamp. The power supply assembly is used to supply power to the light source assembly. Separating the power supply assembly from the light source assembly can effectively disperse the heat generated by the power supply assembly and the light source assembly when working, thereby avoiding the accumulation of heat in a limited space and further improving the overall heat dissipation efficiency of the explosion-proof lamp.

[0100] 8. The explosion-proof lamp provided in the embodiment of the utility model, the light source assembly includes a substrate, a light source arranged on the substrate, and a lens; the power supply assembly includes a shell, a power supply and a power supply terminal arranged in the shell, and a wire connected to the power supply terminal, and the light source assembly and the power supply assembly are electrically connected through the wire. The light source assembly uses the substrate as a support to ensure that the light source is stably installed, reduce damage caused by vibration or impact, and improve overall stability. The lens is used to protect the light source from external damage, optimize light distribution, and improve lighting quality. The modular design of the light source assembly and the power supply assembly facilitates relatively independent installation and replacement, and improves maintenance efficiency.

[0101] 9. The explosion-proof lamp provided in the embodiment of the utility model has a light source cavity and a wiring groove connected to the light source cavity on the inner side of the bottom cover, the light source assembly is arranged in the light source cavity, the power supply assembly is arranged on the side of the bottom cover away from the light source cavity, and the wire passes through the wiring groove and is electrically connected to the substrate. The wire can be hidden inside the lamp body through the wiring groove, reducing the direct contact between the wire and the external environment, reducing the risk of sparks or short circuits caused by exposed wires, and further improving the explosion-proof performance of the lamp. The power supply assembly is arranged on the side of the bottom cover away from the light source cavity, and the power supply assembly and the light source assembly each have a relatively independent heat dissipation space, which can effectively reduce the heat transfer between the two, which is beneficial to the dissipation of heat and reducing the overall temperature rise of the explosion-proof lamp.

[0102] 10. The explosion-proof lamp provided in the embodiment of the utility model is also provided with a sensor, which can detect any motion state of human body, object, etc. within the sensing range. When a person or object enters the sensing area, the explosion-proof lamp can automatically light up without manual switch, which improves the intelligence level of the lighting system. The explosion-proof lamp also includes all the beneficial effects of the above-mentioned lamp body, which will not be repeated here.
