[0014] Preferably, the light source module is located near the center of the aluminum substrate. The light source module includes several concentric circle structures, and several LED beads are equally spaced on each concentric circle structure. The contact area between the aluminum substrate and the cavity is greater than the contact area between the light source module and the aluminum substrate.
[0015] Preferably, the heat dissipation part is located on the end face of the lamp body near the hook, and the heat dissipation fins are formed by equal-spaced recesses along the end face of the lamp body away from the hook. A groove is formed between two adjacent heat dissipation fins. The groove extends radially from the end near the mounting hole to the ventilation opening position in the heat dissipation part, and the ventilation opening is located between two adjacent heat dissipation fins.
[0016] Preferably, the heat dissipation hole is located between two adjacent heat sinks and away from the snap-fit part. Each groove has at least one heat dissipation hole.

[0020] Beneficial Effects: This utility model of a convection-type industrial and mining lamp improves heat dissipation by incorporating heat dissipation components on the lamp body. These components include heat sinks, heat dissipation holes, and ventilation holes. Three heat dissipation components are evenly spaced along the circumference of the lamp body, and all three have identical structural components. The ventilation holes are positioned near the aluminum substrate. This allows air to enter the cavity formed by the lamp body and aluminum substrate from one heat sink and then exit through the other two, creating air convection. Furthermore, the air makes better contact with the aluminum substrate surface as it passes through the cavity, carrying away heat and accelerating airflow within the lamp body. The grooves on both sides of each heat sink allow for greater contact area with the heat sink as air flows through the lamp body, further enhancing heat dissipation, even under poor airflow conditions. The heat dissipation holes ensure timely heat dissipation when air convection is difficult to achieve in the working space. This invention utilizes the heat sink, heat dissipation holes, and ventilation openings within the heat dissipation section to ventilate and dissipate heat from the industrial and mining lamp, which not only greatly improves the heat dissipation effect of the lamp but also extends its service life.

[0031] Example 1
[0032] like Figure 1 , Figure 2As shown, this utility model provides a convection-type industrial and mining lamp, including a lamp body 1, an aluminum substrate 2, a light source module 3, a lens 4, and a hook 5. The lamp body 1 has a mounting hole 105 in the axial direction. The lamp body 1 also has a heat dissipation part 10, which includes a vent 103, a heat sink 101, and a heat dissipation hole 102. The aluminum substrate 2 is located inside the lamp body 1, and one end of the aluminum substrate 2 is fixedly connected to the lamp body 1. The light source module 3 is located at the end of the aluminum substrate 2 away from the lamp body 1. By placing the light source module 3 on the aluminum substrate 2, the heat generated by the light source module 3 is transferred to the outside of the lamp body 1 through the heat dissipation part 10 using the heat dissipation property of the aluminum substrate 2. The lens 4 is snapped into the lamp body 1 at the end near the light source module 3. The hook 5 passes through the mounting hole 105 and is fixedly connected to the lamp body 1.
[0033] The lamp body 1 has a circular disc-shaped structure. Several heat dissipation parts 10 are evenly spaced along the circumference of the lamp body 1, which can greatly improve the heat dissipation effect. The vent 103 is located at one end close to the aluminum substrate 4. On the one hand, when air enters the cavity 11 formed by the lamp body 1 and the aluminum substrate 2 from the vent 103 of one heat dissipation part 10, it can flow out from the vent 103 of the other two heat dissipation parts 10, thereby forming air convection. On the other hand, during the process of air passing through the cavity 11, it can make better contact with the surface of the aluminum substrate 2, and carry the heat on the aluminum substrate 2 out of the cavity 11 in time, thus accelerating the air circulation inside the lamp body 1. The lamp body 1 also includes a latching part 104, which is located at the end of the lamp body 1 away from the hook 5. The latching part 104 has a circular ring structure and is an integral structure with the lamp body 1.
[0034] like Figure 3 As shown, the aluminum substrate 2 has a circular structure and a wiring hole 21 is provided on the aluminum substrate 2. A cavity 11 is provided between the aluminum substrate 2 and the lamp body 1. The wiring hole 21 is located away from the axis of the aluminum substrate 2. A sealing ring 22 is also provided on the side of the aluminum substrate 2 near the lens 4. The diameter of the sealing ring 22 is smaller than the diameter of the aluminum substrate 2. The light source module 3 is electrically connected to the power line 6, and the power line 6 passes through the wiring hole 21.
[0035] The light source module 3 is located near the axis of the aluminum substrate 2. The light source module 3 is composed of several annular structures, which form concentric circles with different diameters. LED beads 31 are evenly spaced in each annular structure. The circular area enclosed by the light source module 3 is smaller than the circular area enclosed by the cavity 11, ensuring that the heat generated by the light source module 3 can be passed through the aluminum substrate 2 in a timely manner.
[0036] like Figure 2As shown, the heat dissipation part 10 is provided on the end face of the lamp body 1 near the hook 5. The heat dissipation fins 101 are formed by equal-spaced recesses along the end face of the lamp body 1 away from the hook 5. A groove is formed between two adjacent heat dissipation fins 101. The groove extends radially from the end of the heat dissipation part 10 near the mounting hole 105 to the ventilation port 103. The ventilation port 103 is located between two adjacent heat dissipation fins 101 and is located at the end of the lamp body 1 near the buckle part 104. The convection heat dissipation type industrial and mining lamp of this utility model utilizes the grooves formed on both sides of each heat dissipation fin 101. When air flows through the lamp body 1, it can contact the heat dissipation fin 101 with a larger contact area, further improving the heat dissipation effect.
[0037] The heat dissipation hole 102 is located between two adjacent heat sinks 101 and away from the buckle part 101. Each groove has at least one heat dissipation hole 102. The heat dissipation hole 102 is a raised columnar structure on the groove formed by the heat sink 101, and the height of the raised heat dissipation hole 102 is less than the height of the heat sink 101. The convection heat dissipation type industrial and mining lamp of this utility model utilizes the heat dissipation hole 102 to ensure that the heat inside the lamp body 1 can flow out from the heat dissipation hole 102 in a timely manner when the air in the working space does not easily form air convection in the ventilation port 103.
[0038] like Figure 4 , Figure 5 As shown, lens 4 includes a light-transmitting part 43, a sealing groove 42, and a snap fastener 41. The light-transmitting part 43 is located near the axis of lens 4. The sealing groove 42 is used to cooperate with the sealing ring 22 to provide sealing and waterproofing. The snap fastener 41 is located on the inner wall of lens 4 near the snap fastener part 104 and is snapped onto the lamp body 1 on the snap fastener part 104. The light-transmitting part 43 includes several annular grooves 43, which form several concentric circles of different diameters. Each annular groove 431 corresponds to a ring-shaped LED bead 31 in the light source module 3. Protrusions 432 are formed on both sides of the annular grooves 431, and the protrusions 432 abut against the aluminum substrate 2 near the end face of lens 4.
[0039] like Figure 6 As shown, the hook 5 also includes a hook body 51, a limiting part 52, and a threaded part 53. The limiting part 52 is located on the side of the hook 5 near the mounting hole 105 and is used to limit the depth of the threaded part 53 of the hook 5 inserted into the mounting hole 105. The hook 5 is fixedly connected to the lamp body 1 by a nut 8. The hook 5 is also provided with a pin 7 at the end away from the threaded part 53. The pin 7 works with the hook 5 to position the miner's lamp and prevent it from falling.
[0040] The above description is merely a specific embodiment of this utility model. Those skilled in the art will understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
