Description

Technical Field

[0001] This utility model belongs to the field of lighting device technology, and in particular relates to an industrial and mining lamp and its heat dissipation housing. Background Technology

[0002] Industrial and mining lamps are high-power lighting devices widely used in large spaces such as industrial plants and stadiums. To meet the high illuminance requirements of such environments, existing technologies typically employ a high-density arrangement of multiple LED beads on a ring or circular light strip to achieve a greater luminous flux output per unit area.

[0003] However, LED chips generate a significant amount of heat when emitting light. A dense arrangement of multiple chips leads to a high concentration of heat in the central area of ​​the light-emitting surface, creating a "heat island effect." Currently, the primary heat dissipation method for these industrial and mining lamps relies on metal heat sinks on the back of the lamp. Heat is transferred from the chips to the fins via thermal conduction, and then passively dissipated through natural convection between the fins and the air. However, the clustered arrangement of chips causes heat transfer between them, hindering heat dissipation. Heat sinks alone are insufficient to meet the heat dissipation requirements of such a clustered arrangement, easily leading to excessively high chip temperatures and reducing the lamp's lifespan.

[0004] Therefore, for high-brightness industrial and mining lamps that employ a multi-LED cluster arrangement, the problem of insufficient heat dissipation of the LEDs, leading to excessively high LED temperatures, is a technical issue that urgently needs to be addressed by those skilled in the art.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0006] This disclosure provides at least one industrial and mining lamp and its heat dissipation housing.

The ventilation channel is divided into multiple arc-shaped air ducts distributed circumferentially by the connecting strip.

[0008] In one optional embodiment, the connecting strip has a hollow wire groove inside for laying the wires connecting the annular light strip.

[0009] In one alternative embodiment, heat dissipation fins are provided on the back of the housing, and the heat dissipation fins are evenly arranged circumferentially.

[0010] In one alternative embodiment, the heat dissipation fins extend from the center of the housing in a circumferential direction to cover the arc-shaped air duct.

[0011] In one alternative embodiment, a power supply unit is further included, which is mounted above the housing via a mounting post, thereby creating a gap between the power supply unit and the housing.

[0012] In one optional embodiment, a through hole is provided at the center of the outer casing, and the through hole communicates with the gap between the power supply unit and the outer casing, together forming an axial central ventilation channel.

[0013] In one alternative implementation, the number of ring-shaped light strips on a single ring mounting structure does not exceed two, in order to reduce heat buildup within the same ring.

[0014] Secondly, embodiments of this disclosure also provide a heat dissipation housing for industrial and mining lamps, comprising: shell; Multiple concentric ring-shaped mounting structures are disposed inside the housing and arranged radially outward from the center of the housing for mounting ring-shaped light strips; A ventilation channel penetrating the outer shell is formed between adjacent annular mounting structures, and the adjacent annular mounting structures are connected by a connecting strip. The ventilation channel is divided into multiple arc-shaped air ducts distributed circumferentially by the connecting strip.

[0015] In one optional embodiment, the connecting strip has a hollow wire groove inside for laying the wires connecting the annular light strip.

[0016] In one alternative embodiment, the back of the housing is provided with heat dissipation fins, which are evenly arranged circumferentially and extend from the center of the housing to the circumference to cover the arc-shaped air duct.

[0017] The beneficial effect of this utility model is that, by setting up a concentric radial ring mounting structure and forming a ventilation channel through the outer shell between adjacent ring mounting structures, an effective air circulation path is formed in the area where the lamp beads are gathered by air thermal convection, which can continuously remove heat, thereby avoiding the problem of mutual heat transfer and heat accumulation caused by the clustering and arrangement of lamp beads.

[0029] Research has revealed a drawback of existing technology: LED chips generate a significant amount of heat when emitting light. The dense arrangement of multiple chips leads to a high concentration of heat in the central area of ​​the light-emitting surface, creating a "heat island effect." Currently, the primary heat dissipation method for these industrial and mining lamps relies on metal heat sinks on the back of the lamp. Heat is transferred from the chips to the fins through heat conduction, and then passively dissipated through natural convection between the fins and the air. However, the clustered arrangement of chips causes heat transfer between them, hindering heat dissipation. Heat sinks alone are insufficient to meet the heat dissipation requirements of such a densely arranged array, easily leading to excessively high chip temperatures and reducing the lamp's lifespan.

[0030] Based on the above research, this disclosure provides an industrial and mining lamp. By optimizing the physical structure of the lamp, ventilation channels are set between the dense annular light strips. These ventilation channels construct active air convection channels, which can continuously remove the heat emitted by the lamp beads and reduce heat transfer between the lamp beads, thus solving the above problems.

[0031] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] See Figure 1This disclosure provides an industrial and mining lamp and its heat dissipation housing, including: a housing 100, which constitutes the main support structure of the industrial and mining lamp, and its shape is generally circular or dish-shaped. The housing 100 is preferably made of a metal with good thermal conductivity, such as aluminum alloy, to facilitate the conduction of some heat to the entire surface of the housing 100 for dissipation. Inside the housing 100, multiple concentrically arranged annular mounting structures 200 are provided. These annular mounting structures 200 are arranged radially outward from the center of the housing 100, forming a multi-layered concentric array. The annular mounting structures 200 can be integrally formed with the housing 100 or fixedly connected by screws or other means. At least one annular light strip 210 is provided on each annular mounting structure 200. The annular light strip 210 is a flexible circuit board on which multiple LED beads are mounted for lighting functions. Through this multi-ring concentric layout, a large number of LED beads can be integrated within a limited area, meeting the high brightness requirements of the industrial and mining lamp.

[0035] See Figure 1 and Figure 2 Ventilation channels are formed between adjacent annular mounting structures 200, penetrating the outer casing 100. This means that air can enter from the bottom of the lamp, flow through the gaps between these annular structures, and finally exit from the top of the lamp, forming a complete airflow path. To ensure the overall mechanical strength and stability of the multiple concentric annular mounting structures 200, adjacent annular mounting structures 200 are connected and fixed by connecting strips 400. These connecting strips 400 are distributed circumferentially, dividing a complete annular ventilation channel into multiple circumferentially distributed arc-shaped air ducts 300. During operation, the heat generated by the LED beads causes the surrounding air to rise. Based on the "chimney effect," cool air is continuously replenished from the opening below the lamp, while hot air is accelerated out through the arc-shaped air ducts 300 (e.g., ...). Figure 2 (As indicated by the middle arrow). This active convection process acts directly on the annular light strip 210 area where heat generation is most concentrated, greatly improving heat dissipation efficiency.

[0036] See also Figure 1 and Figure 2 In some embodiments, a hollow wire groove (not shown) extending along the length of the connecting strip 400 is provided inside the connecting strip 400. The hollow wire groove is formed inside the solid material of the connecting strip 400, and its cross-sectional shape can be set to rectangular, circular, or other suitable shapes. During wiring, the wires connecting each ring light strip 210 are housed in the hollow wire groove. With this arrangement, on the one hand, the structure of the connecting strip 400 itself can provide storage space for the wires, avoiding the wires being exposed in the ventilation channel and obstructing airflow; on the other hand, the solid structure of the connecting strip 400 can form a full-circumferential wrapping protection for the wires in the wire groove, preventing the wires from being damaged by external pulling or wear.

[0037] See Figure 3 In some embodiments, heat dissipation fins 110 are provided on the back of the housing 100, and the heat dissipation fins 110 are evenly arranged along the circumference of the housing 100. The heat dissipation fins 110 extend radially from the center of the housing 100 in a circumferential direction, such that each heat dissipation fin 110 can cover at least one arc-shaped air duct 300. The radial extension direction of the heat dissipation fins 110 intersects with the natural upward path of hot air in the arc-shaped air duct 300 (i.e., a generally vertically upward direction). This arrangement allows the rising hot air to contact a larger area of ​​the heat dissipation fin surface 110, achieving sufficient heat exchange.

[0038] See Figure 1 and Figure 4 In some embodiments, the industrial lamp further includes a power supply unit 500, which is mounted above the housing 100 via multiple mounting posts 510. The mounting posts 510 are evenly distributed circumferentially, and their height is set to create a gap 600 between the power supply unit 500 and the top surface of the housing 100. This elevated mounting method provides stable support for the power supply unit 500 and avoids direct contact between the power supply unit 500 and the housing 100, preventing the heat generated by the power supply unit 500 from being directly conducted to the lamp body. Preferably, a through hole 120 is provided at the center of the housing 100, which communicates with the gap 600 to form an axial central ventilation channel. Hot air flows upward through the central through hole 120, enters the gap 600 between the power supply unit 500 and the housing 100, and finally exits from the gaps around the power supply unit 500. Through the above structural design, this utility model not only optimizes the installation method of the power supply unit 500, but also cleverly utilizes the space between the power supply unit 500 and the outer casing 100 to form an axial central ventilation channel. This ventilation channel works in conjunction with the radial arc-shaped air duct 300 to form a highly efficient three-dimensional heat dissipation path, significantly improving the overall heat dissipation efficiency of the lamp, especially enhancing the heat dissipation effect on the central area where the lamp beads are concentrated, thereby further ensuring the long-term operational reliability of the lamp.

[0039] See Figure 1 and Figure 2In some embodiments, the number of annular LED strips 210 on each annular mounting structure 200 is limited to no more than two. In practical applications, one or two annular LED strips 210 can be arranged on each annular mounting structure 200 depending on the required brightness level. If three or more LED strips are densely arranged on a single annular mounting structure 200, a new, high-density linear heat source will be formed on the same ring. This localized heat accumulation will significantly weaken or even negate the overall heat dissipation benefits of the ventilation channel. Limiting the number of LED strips to two or less ensures that even on the same ring, there is sufficient spacing between the LEDs for heat dissipation, avoiding heat accumulation.

[0040] See Figure 1 and Figure 2 Some embodiments also provide a heat dissipation housing for industrial and mining lamps, including: a housing 100; a plurality of concentrically arranged annular mounting structures 200 disposed inside the housing 100 and arranged radially outward from the center of the housing 100 for mounting annular lamp strips 210; wherein, a ventilation channel penetrating the housing 100 is formed between adjacent annular mounting structures 200, and adjacent annular mounting structures 200 are connected by connecting strips 400; the ventilation channel is divided by the connecting strips 400 into a plurality of circumferentially distributed arc-shaped air ducts 300.

[0041] In summary, this industrial and mining lamp, by setting up a concentric radial ring mounting structure 200 and forming a ventilation channel penetrating the outer shell 100 between adjacent ring mounting structures 200, utilizes air thermal convection to form an effective air circulation path in the lamp bead gathering area, which can continuously remove heat, thereby avoiding the problem of mutual heat transfer and heat accumulation caused by the clustering and arrangement of lamp beads.

[0042] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0044] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0045] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
