Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and more specifically, to an industrial and mining lamp. Background Technology

[0002] Industrial and mining lamps are high-efficiency lighting devices specifically designed for large spaces such as industrial plants, warehouses, and stadiums. They utilize LED light sources and offer advantages such as energy saving, high brightness, long lifespan, and low maintenance costs. These lamps have a robust structure, typically possess a high level of protection, and can withstand complex environments such as dust and humidity.

[0003] Industrial and mining lamps typically consist of a housing, an LED chip board, and a light-transmitting cover. The LED chip board is installed inside the housing, and the light-transmitting cover is fitted over the lower side of the housing, shielding the LED chip board within the housing. The light emitted by the LED chip board can pass through the light-transmitting cover and be emitted outwards, thus providing illumination. To achieve light diffusion, a lens structure is usually pre-formed on the surface of the light-transmitting cover. This lens structure can diffuse the light and create an appropriate coverage area.

[0004] However, most industrial and mining lamps on the market currently suffer from insufficient lighting flexibility. The light-transmitting cover often adopts a fixed structure, directly installed on the housing. The positional distance between the lens structure on the light-transmitting cover and the LED lamp chip board is fixed, making it impossible to adjust the lighting range of the light output angle, thus limiting the flexibility of industrial and mining lamps in actual use. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an industrial and mining lamp that can dynamically adjust the distance between the lens structure on the light-transmitting cover and the LED lamp bead board, thereby achieving continuous adjustment of the light output angle and illumination range.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an industrial and mining lamp, comprising a housing, an LED bead board, and a light-transmitting cover. The lower part of the housing is open, and the light-transmitting cover is fitted over the open portion of the lower part of the housing. The LED bead board is installed in the cavity formed by the housing and the light-transmitting cover, and the LED bead board is fixedly connected to the housing. The outer edge of the light-transmitting cover is embedded in the open portion of the housing and can rotate and be adjusted up and down along the circumference of the housing. Four positioning holes are provided on the outer periphery of the housing, and pins are inserted into the positioning holes. A limiting groove is provided on the outer edge of the light-transmitting cover, and the position of the limiting groove corresponds to the positioning holes. One end of the pin passes through the positioning hole and can abut against the inner wall of the limiting groove. The limiting groove is arranged along the circumference of the outer edge and is inclined up and down.

[0007] By adopting the above solution, and by setting an inclined circumferential limiting groove on the outer edge of the light-transmitting cover, and configuring insertable pins at corresponding positions on the housing, the light-transmitting cover can be both rotated circumferentially and flexibly adjusted vertically relative to the housing. This structure allows users to change the position of the pins in the inclined limiting groove by rotating the light-transmitting cover, thereby continuously and precisely adjusting the relative height between the light-transmitting cover and the housing, and thus changing the relative distance between the LED bead board and the lens of the light-transmitting cover, ultimately achieving free control over the light emission angle and illumination range.

[0008] The present invention is further configured such that a plurality of limiting holes are formed in the limiting groove, and the end of the pin can be partially embedded in the limiting hole. Each limiting groove is provided with three limiting holes, which are respectively located at both ends and the middle of the limiting groove.

[0009] By adopting the above scheme, by setting a limiting hole at both ends and the middle position in each inclined limiting groove, the end of the pin can be partially embedded in it, thus forming multiple clear positions.

[0010] The present invention is further configured such that a plurality of LED beads are arranged on the lower side of the LED bead board, and each LED bead is arranged in a concentric circle; the light-transmitting cover is integrally formed with a lens structure, the lens structure is arranged in a concentric circle, and corresponds one-to-one with the concentric circle of each LED bead.

[0011] By adopting the above scheme, the LED beads are arranged in concentric circles on the lower side of the bead plate, and the lens structure on the light-transmitting cover also adopts a strictly corresponding concentric circle distribution. During the rotation and adjustment of the light-transmitting cover, the concentric circle distribution structure of the LED beads can always be opposite to the concentric circle distribution structure of the lens. After the two deflect, they can always scatter normally.

[0012] The present invention is further provided with a rotating handle on the lower side of the light-transmitting cover.

[0013] By adopting the above solution and setting a rotating handle on the lower side of the light-transmitting cover, an ergonomic force point is provided for the user, making the operation of rotating and adjusting the light-transmitting cover more labor-saving and convenient, and significantly improving the practicality and safety of adjusting the angle of industrial and mining lamps.

[0014] The present invention is further provided that a plurality of heat dissipation holes are uniformly arranged on the outer edge of the inner periphery of the shell, and the heat dissipation holes are circumferentially distributed for heat dissipation of the shell.

[0015] By adopting the above solution, and by uniformly setting multiple circumferentially distributed heat dissipation holes on the inner and outer edges of the housing, the effective heat dissipation area of ​​the housing is significantly increased, forming an efficient and uniform air convection channel, realizing rapid heat dissipation of the LED lamp bead board and internal components, effectively reducing the core operating temperature, delaying light decay and extending the life of the lamp.

[0016] The present invention is further configured such that an annular groove is formed on the outer periphery of the outer edge of the light-transmitting cover, and a sealing ring is embedded in the annular groove, the sealing ring sealing the outer edge of the light-transmitting cover with the inner periphery of the shell.

[0017] By adopting the above solution, and by creating an annular groove on the outer edge of the light-transmitting cover and embedding a sealing ring, a highly efficient seal is achieved at the joint between the light-transmitting cover and the housing. This structure effectively prevents dust, moisture, and other contaminants from entering the lamp fixture through the assembly gaps, protecting core components such as the LED chip board and driver power supply from corrosion.

[0018] The present invention is further configured such that a groove is provided on the outer edge of the light-transmitting cover corresponding to the lower side of the annular groove, and a damping block is embedded in each groove. Part of the damping block protrudes from the outer edge and can abut against the inner circumference of the shell.

[0019] By adopting the above solution, a groove with a damping block is set on the lower side of the annular groove on the outer edge of the light-transmitting cover, and the damping block protrudes and abuts against the inner circumference of the housing. This provides moderate frictional resistance during the rotation and up-down adjustment of the light-transmitting cover, effectively preventing the light-transmitting cover from accidentally shifting due to its own weight or vibration, and enhancing the structural stability and reliability of the lamp under various working conditions.

[0020] The present invention is further configured such that the outer circumferential edge of the damping block is provided with a continuous tooth structure, and a protruding tooth is fixedly provided on the inner circumferential wall of the housing at a position corresponding to the damping block, which meshes with the damping block.

[0021] By adopting the above solution, a continuous locking tooth structure is set on the outer circumference of the damping block, and a protruding locking tooth is fixed at the corresponding position on the inner circumferential wall of the housing, so that the two form a mutually meshing locking limit. This structure can provide a clear sense of the stop when the light-transmitting cover is rotated to a specific angle, ensuring that the adjustment position is locked, and effectively preventing the light-transmitting cover from accidentally rotating or slipping due to vibration or external impact during use.

[0022] The present invention is further configured such that a drive controller is fixedly installed on the upper side of the housing, and a lifting ring is fixedly installed on the side of the drive controller facing away from the housing; the housing and the drive controller are fixedly connected by several columns, and the columns and the housing are integrally formed; the housing and the drive controller form an interstitial space; an external wiring terminal is connected to the upper side of the housing, and the external wiring terminal is connected to the housing by a sealing connector, and the external wiring terminal is located between the drive controllers.

[0023] By adopting the above solution, a stable and compact top structure is formed by fixing the drive controller to the upper side of the housing using an integrally molded column and installing a lifting ring above it. The external wiring terminals are reliably connected to the housing through sealed connectors and are reasonably arranged on the side of the drive controller for easy on-site installation and maintenance.

[0024] In summary, this utility model has the following beneficial effects:

[0025] The adjustable light-transmitting cover structure allows for flexible changes in the relative installation height between the light-transmitting cover and the housing, thereby dynamically adjusting the relative distance between the lens on the surface of the light-transmitting cover and the internal LED chip board. This distance variation enables adjustment of the light emission angle and illumination range. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Example 1

[0041] This embodiment discloses an industrial and mining lamp, referring to... Figures 1-7 As shown, the device includes a housing 1, an LED bead board 4, and a light-transmitting cover 5. The housing 1 is made of aluminum alloy and is roughly disc-shaped. The lower part of the housing 1 is open, forming an inner cavity that can accommodate internal components. The light-transmitting cover 5 covers the open part of the lower part of the housing 1. The LED bead board 4 is installed in the cavity formed by the housing 1 and the light-transmitting cover 5. The LED bead board 4 is fixedly connected to the housing 1, and several LED beads are arranged on the lower side of the LED bead board 4.

[0042] Reference Figure 4 , Figure 5 The outer edge 50 of the light-transmitting cover 5 is embedded in the opening of the housing 1 and can rotate and be adjusted up and down around the housing 1. By rotating and adjusting the light-transmitting cover 5, the light-transmitting cover 5 can be guided along a thread-like track, thereby forming an adjustment in the up and down direction, which can realize the relative adjustment between the light-transmitting cover 5 and the LED lamp bead board 4.

[0043] Reference Figure 7A limiting groove 52 is formed on the outer edge 50 of the light-transmitting cover 5. The limiting groove 52 is arranged circumferentially along the outer edge 50 and is inclined vertically. Four positioning holes 101 are formed on the outer periphery of the housing 1, and correspondingly, there are also four limiting grooves 52, which correspond one-to-one with the positioning holes 101. A retractable pin 6 is inserted into the positioning hole 101, and one end of the pin 6 can extend into the limiting groove 52 and abut against its inner wall. Several limiting holes 53 are formed in the limiting groove 52.

[0044] The position of the limiting groove 52 corresponds to that of the positioning hole 101. One end of the pin 6 passes through the positioning hole 101 and can abut against the inner wall of the limiting groove 52. The outer circumference of the pin 6 can be provided with external threads, roughly resembling a screw-like structure, and is threadedly connected to the positioning hole 101.

[0045] Each limiting groove 52 is provided with three limiting holes 53, which are located at both ends and the middle of the limiting groove 52, respectively. When the user rotates the light-transmitting cover 5, the end of the pin 6 can be partially inserted into the limiting hole 53. The pin 6 can selectively abut against the three different limiting holes 53, forming three distinct adjustment positions, and corresponding adjustment states can also be formed between the positions of the limiting holes 53.

[0046] To facilitate the rotation and adjustment of the light-transmitting cover 5, a rotating handle 54 is located on the lower side of the light-transmitting cover 5. By loosening the pin 6 and manually rotating the rotating handle 54, the entire light-transmitting cover 5 can be rotated. Then, the pin 6 can be tightened to achieve adjustment and reliable locking of the light-transmitting cover 5 at three different height positions, preventing slippage during use.

[0047] To achieve a seal between the light-transmitting cover 5 and the housing 1, an annular groove 51 is formed on the outer periphery of the outer edge 50 of the light-transmitting cover 5, and a sealing ring 7 is embedded in the annular groove 51. The sealing ring 7 is made of rubber material and can maintain a sealed state during the rotation and adjustment of the housing 1, achieving a reliable seal between the light-transmitting cover 5 and the inner periphery of the housing 1, effectively preventing dust and moisture from entering. A rotating handle 5 is provided on the lower side of the light-transmitting cover 5 for easy rotation and adjustment by the user.

[0048] During the rotation and adjustment of the light-transmitting cover 5, the lens structure 56 on the light-transmitting cover 5 will undergo relative displacement with the LED beads on the LED bead board 4. Therefore, further design of the LED beads and lens structure 56 is required to ensure that the light can be effectively and normally diffused. Specifically, each LED bead is arranged in a concentric circle, and the center of the circle coincides with the rotation axis of the light-transmitting cover 5. The light-transmitting cover 5 is integrally formed with a lens structure 56, which includes multiple optical lenses, each arranged in a concentric circle. The concentric circle of each lens structure 56 corresponds one-to-one with the concentric circle of each LED bead. This concentric distribution structure ensures that each LED bead always corresponds to each lens structure 56 during rotation, thus ensuring a normal light diffusion effect.

[0049] Reference Figures 1-3 As shown, a drive controller 2 is fixedly installed on the upper side of the housing 1. The drive controller 2 can drive the LED lamp bead board 4 and can realize functions such as power adjustment, color temperature adjustment, and sensor connection. The specific structure and principle of the drive controller 2 are conventional technologies in this field and will not be described in detail here. A lifting ring 3 is fixedly installed on the side of the drive controller 2 facing away from the housing 1. The lifting ring 3 can realize the hoisting of the lamp.

[0050] The housing 1 and the drive controller 2 are fixedly connected by several columns, and the columns are adapted to the screw holes on the columns by bolts. The columns and the housing 1 are an integral structure. The housing 1 and the drive controller 2 form an interval space. The external terminal 8 is connected to the upper side of the housing 1. The external terminal 8 achieves a reliable sealed connection with the housing 1 through a sealing connector. The external terminal 8 is located in the interval space between the housing 1 and the drive controller 2, which protects the cable and facilitates access.

[0051] Reference Figure 1 As shown, multiple heat dissipation holes 102 are evenly arranged on the inner periphery and outer edge of the housing 1. The heat dissipation holes 102 are circumferentially distributed to dissipate heat from the housing 1 and further optimize the overall heat dissipation performance.

[0052] Example 2

[0053] This embodiment discloses an LED street light, which is based on Embodiment 1 and further refers to... Figures 8-12 Please provide a detailed explanation.

[0054] In this embodiment, the outer edge 50 of the light-transmitting cover 5 is provided with four arc-shaped grooves 55 evenly distributed along the circumference, and the arc-shaped grooves 55 are located below the annular grooves 51. Each arc-shaped groove 55 is embedded with a damping block 103, which may be made of rubber.

[0055] A portion of the damping block 103 protrudes from the outer edge 50. When the light-transmitting cover 5 is assembled inside the housing 1, the protruding portion can maintain continuous elastic contact with the inner peripheral wall of the housing 1, forming a uniform frictional damping effect. The damping block 103 can provide appropriate frictional resistance during the rotation and vertical adjustment of the light-transmitting cover 5, effectively preventing the light-transmitting cover 5 from accidentally shifting due to its own weight or vibration, and enhancing the structural stability and reliability of the lamp under various working conditions.

[0056] Furthermore, continuous locking teeth 104 are machined on the outer circumferential direction of the damping block 103. Simultaneously, on the inner circumferential wall of the housing 1, an integrally formed protruding locking tooth 104 is fixedly provided at a position corresponding to each damping block 103. When the user rotates the light-transmitting cover 5 to adjust the angle or height, the locking teeth 104 on the damping block 103 will engage with the protruding locking teeth 105 on the inner wall of the housing 1 for limiting the position. This limiting mechanism not only provides a clear sense of the adjustment position and realizes multi-position positioning, but also, through the mechanical self-locking effect formed by the interlocking teeth after adjustment, effectively prevents the light-transmitting cover 5 from accidentally rotating or slipping due to vibration or external impact, greatly enhancing the controllability and reliability of the lighting state.

[0057] Furthermore, referring to Figure 12 As shown, a damping groove 106 is provided on the inner circumference of the housing 1; and the position of the damping groove 106 corresponds to the damping block 103. The damping block 103 can be partially embedded in the damping groove 106. Moreover, the protruding locking teeth 105 are also located on the inner circumferential wall of the damping groove 106 to prevent the protruding locking teeth 105 from protruding on the inner circumference of the housing 1 and affecting the normal installation of the light-transmitting cover 5.

[0058] Reference Figure 12 As shown, the height of the damping groove 106 is greater than that of the damping block 103. During the up-and-down adjustment of the housing 1, the damping block 103 can move normally within the damping groove 106. Moreover, since the damping block 103 is embedded in the damping groove 106, the lower sidewall of the damping groove 106 can limit the movement of the damping block 103. When the housing 1 suddenly falls, the lower sidewall of the damping groove 106 can block and support the damping block 103, preventing the housing 1 from accidentally falling during the adjustment process.

[0059] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
