Description

Technical Field

[0001] This application relates to the field of industrial lighting technology, and in particular to an industrial and mining lamp. Background Technology

[0002] Industrial lights, also known as industrial signal lights, equipment status indicators, or machinery warning lights, are indispensable visual signaling devices in modern industrial automation and machinery. Their core function is to provide operators and maintenance engineers with clear, immediate, and long-distance visible information regarding equipment operating status, fault alarms, process completion, or safety warnings in complex, noisy, and even hazardous production environments. Currently, industrial and mining lamps have developed into a technologically mature and diverse product system, with mainstream products generally using high-brightness, long-life, and low-power LEDs as the light source. The overall structure includes a lamp housing bracket, an LED light source module mounted on the bracket, and a lamp body shell covering the LED light source module.

[0003] Regarding the aforementioned technologies, the beam angle emitted by existing industrial and mining lamps cannot be changed, resulting in 30-50% of the light illuminating non-target areas, such as walls or adjacent equipment, which interferes with the visual operations of other workstations and affects the interface readings of some equipment. Summary of the Invention

[0004] In order to reduce the impact of industrial and mining lamps on the operations of other workstations, this application provides an industrial and mining lamp.

[0005] The industrial and mining lamp provided in this application adopts the following technical solution: An industrial and mining lamp includes a lamp housing support, a light source assembly disposed on the lamp housing support, an adjustment mechanism mounted on the lamp housing support for adjusting the lighting range, and a cleaning mechanism disposed on the adjustment mechanism. The light source assembly has a light-transmitting plate for light to pass through. The adjustment mechanism includes an adjustment frame disposed on the lamp housing support, an adjustment cover rotatably mounted on the lamp housing support for covering the light-transmitting plate, and an adjustment drive assembly for driving the adjustment frame to rotate.

[0006] By adopting the above technical solution, the adjustment mechanism can adjust the lighting range, avoid light shining on non-target areas, reduce interference with visual operations at other workstations and the impact on equipment interface readings; the cleaning mechanism can clean the light-transmitting plate to ensure the lighting effect.

[0007] Optionally, the adjusting cover includes four sets of circumferentially arranged light-shielding plates, elastic extension plates connecting adjacent light-shielding plates, and a rotating seat disposed on the light-shielding plates, the rotating seat being fixed to the lamp housing bracket.

[0008] By adopting the above technical solution, the adjustment cover is composed of four sets of circumferentially arranged light-shielding plates, elastic extension plates and rotating seats. The rotating seats are fixed to the lamp housing bracket and can cover the light-transmitting plate. With the help of the adjustment drive component, the adjustment cover can be rotated, thereby adjusting the lighting range of the industrial and mining lamp, avoiding light from shining on non-target areas, reducing interference with visual operations at other workstations and the impact on equipment interface readings.

[0009] Optionally, the elastic extension sheet includes a connecting portion disposed on the inner side of the light-shielding sheet and an extension portion connecting the two sets of connecting portions, wherein the extension portion is provided with extension folds for extending and deforming toward the connecting portions on both sides.

[0010] By adopting the above technical solution, the connecting part is set inside the light shield, the extension part connects the two sets of connecting parts, and the extension folds on the extension part can extend and deform towards the connecting parts on both sides, which enables the adjustment cover to have better adaptability and deformability when adjusting the lighting range, ensuring that the gap between the two sets of light shields can be covered by the elastic extension piece during the adjustment process, ensuring that the light is always inside the adjustment cover, and reducing the light from shining on non-target areas.

[0011] Optionally, the adjustment drive assembly includes a rotating shaft passing through the rotating seat, transmission bevel gears disposed at both ends of the rotating shaft, and a rotation drive component disposed on one of the rotating shafts. The top of the light-shielding sheet is fixedly connected to the rotating shaft, and the rotating seat has a rotation clearance groove for the light-shielding sheet to rotate.

[0012] By adopting the above technical solution, the rotating drive component drives the rotating shaft to rotate, and the transmission bevel gear drives other rotating shafts to rotate synchronously, so that the light-shielding plate fixedly connected to the rotating shaft rotates in the rotating clearance groove, thereby realizing the synchronous rotation of multiple sets of light-shielding plates of the adjustment cover, thereby adjusting the lighting range of the industrial and mining lamp and preventing light from shining on non-target areas.

[0013] Optionally, the adjusting frame and the light-shielding sheet are arranged in a one-to-one correspondence. The adjusting frame includes a first frame disposed at one end of the rotation clearance groove, a second frame disposed at the other end of the rotation clearance groove, and a frame track connecting the first frame and the second frame. The first frame has a placement groove for arranging the light-shielding sheet on the side facing the second frame, and the second frame has a limiting groove on the side facing the first frame to restrict the light-shielding sheet from continuing to rotate.

[0014] By adopting the above technical solution, the adjustment frame is set to correspond with the light shield. The placement groove of the adjustment frame allows the light shield to be arranged, and the limiting groove can restrict the light shield from continuing to rotate, which helps to adjust the cover of the light-transmitting plate, thereby realizing the adjustment of the lighting range of the industrial and mining lamp.

[0015] Optionally, the light-shielding plate has a rotating wheel at the end away from the rotating seat, and the frame track has a track groove for arranging the rotating wheel.

[0016] By adopting the above technical solution, a rotating wheel is set at the end of the light-shielding plate away from the rotating seat, and a track groove is set on the frame track for the rotating wheel to be arranged. When the light-shielding plate rotates to adjust the lighting range, the rotating wheel can roll along the track groove, providing stable support and guidance for the rotation of the light-shielding plate, ensuring the smoothness and stability of the rotation of the light-shielding plate, and thus ensuring that the adjustment mechanism can more accurately adjust the lighting range of the industrial and mining lamp.

[0017] Optionally, the cleaning mechanism includes a cleaning transmission component disposed on the rotating shaft, a cleaning drive rod connected to the cleaning rotating component, a cleaning mounting plate disposed at the end of the cleaning drive rod, a cleaning eccentric rod eccentrically fixed to the cleaning mounting plate, and a cleaning flapping rod that slides and cooperates with the cleaning eccentric rod, wherein the end of the cleaning flapping rod is rotatably mounted on the bottom of the lamp housing bracket.

[0018] By adopting the above technical solution, when the rotating shaft of the adjustment mechanism rotates, and when the adjustment drive component drives the rotating shaft to rotate, the cleaning transmission component can simultaneously drive the cleaning flapping rod to swing up and down, so that the cleaning flapping rod hits the light-transmitting plate and knocks off the dust.

[0019] Optionally, the top of the lamp housing bracket is also provided with a locking mechanism for controlling the circumferential positioning of the rotating shaft and the light shield. The locking mechanism includes a locking push rod, a locking slide rod disposed at the end of the locking push rod and corresponding to the rotating shaft, and a locking insert rod slidably disposed at the end of the locking slide rod. The rotating base has a first arc hole corresponding to the locking rod, and the light-shielding sheet has a locking hole corresponding to the first arc hole. When the light-shielding sheet is located in the placement slot, the locking hole and the locking rod correspond to each other.

[0020] By adopting the above technical solution and setting the locking mechanism, the light-shielding sheet and the rotating shaft can be locked and unlocked, so that in the unlocked state, the light-transmitting plate can be cleaned by tapping without changing the lighting range.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The adjustment mechanism can adjust the lighting range, change the beam angle, reduce light shining on non-target areas, avoid interfering with the visual operations of other workstations and affecting the interface readings of the equipment; 2. The adjustment mechanism allows the industrial and mining lamps to adjust the lighting range according to actual needs, thereby improving the utilization rate of light; 3. The cleaning mechanism can clean the light-transmitting plate to ensure the light transmission effect and maintain the normal illumination of the industrial and mining lamps.

For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0032] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0033] Reference Figure 1 and Figure 2 The present application provides an industrial and mining lamp, which includes a lamp housing bracket 1, a light source assembly 2 disposed on the lamp housing bracket 1, and an adjustment mechanism 3 installed on the lamp housing bracket 1 for adjusting the lighting range.

[0034] Specifically, the light source assembly 2 includes LED chips and a light-transmitting plate 21. The LED chips can be high-brightness, long-life, and low-power LED chips to provide stable and bright light. The light-transmitting plate 21 is typically made of transparent plastic or glass, and its shape is generally circular or square; in this application, the light-transmitting plate 21 is square. The light-transmitting plate 21 is mounted on the lamp housing bracket 1, serving to protect the LED chips and allow light to pass through. Of course, the LED chips can be replaced with other types of energy-saving lighting fixtures, and the light-transmitting plate 21 can also be made of materials with special optical properties, such as a diffuse reflection light-transmitting plate 21, to improve the lighting effect.

[0035] The adjustment mechanism 3 includes an adjustment frame 31 fixed to the lamp housing bracket 1, an adjustment cover 32 rotatably mounted on the lamp housing bracket 1 and used to cover the light-transmitting plate 21, and an adjustment drive assembly 33 for driving the adjustment cover 32 to rotate. This structural combination allows the adjustment mechanism 23 to change the illumination range of the industrial lamp, reducing light illuminating non-target areas, avoiding interference with visual operations at other workstations and affecting equipment interface readings. Simultaneously, the cleaning mechanism 4 can clean the light-transmitting plate 21 to ensure optimal light transmission.

[0036] Reference Figure 3The adjusting cover 32 includes four circumferentially arranged light-shielding plates 321, elastic extension plates 322 connecting adjacent light-shielding plates 321, and a rotating seat 323 disposed on the top of the light-shielding plates 321. The rotating seat 323 is fixed to the lamp housing bracket 1, and the light-shielding plates 321 and the rotating seat 323 are rotatably engaged. The light-shielding plates 321 are generally made of opaque metal or plastic plates, and their cross-section is trapezoidal. The four sets of light-shielding plates 321, when arranged circumferentially, can form a ring-like structure to block the light emitted by the light source. The elastic extension plates 322 are used to connect adjacent light-shielding plates 321, ensuring that the light-shielding plates 321 can deform flexibly when rotated. The rotating seat 323 is usually made of metal or plastic, and its interior has a structure for the light-shielding plates 321 to rotate. The rotating seat 323 can also be made of a self-lubricating material to reduce frictional resistance during rotation.

[0037] Reference Figure 2 and Figure 4 The adjustment drive assembly 33 includes a rotating shaft 331 passing through the rotating seat 323, a transmission bevel gear 332 fixed at both ends of the rotating shaft 331, and a rotation drive member 333 disposed at the end of one of the rotating shafts 331. The top of the light shield 321 has a fixing through hole 3212 sleeved on the rotating shaft 331. The fixing through hole 3212 and the rotating shaft 331 are circumferentially limited so that the rotating shaft 331 can drive the light shield 321 to rotate synchronously.

[0038] The rotating base 323 is located on the top of the lamp housing bracket 1. Its bottom is provided with a rotation clearance groove 3231 for the light shield 321 to be inserted and installed. The rotation clearance groove 3231 provides space for the rotation of the light shield 321, ensuring that the light shield 321 can rotate smoothly.

[0039] The rotating shaft 331 is generally made of metal, possessing high strength and rigidity. The transmission bevel gears 332 at both ends are used to achieve synchronous transmission between adjacent rotating shafts 331. The rotation drive 333 can be a motor, which drives one set of rotating shafts 331 to rotate, thereby driving the synchronous rotation of the four sets of light-shielding plates 321. The rotation drive 333 can also be manually driven, such as with a crank, which can save energy in situations where frequent adjustments are not required.

[0040] The elastic extension piece 322 includes a connecting portion 3221 disposed inside the light-shielding sheet 321 and an extension portion 3222 connecting two sets of connecting portions 3221. The light-shielding sheet 321 has connecting portions 3221 on both the left and right sides facing the central axis of the light-transmitting plate 21. The extension portion 3222 is used to connect the two sets of connecting portions 3221 of adjacent sets of light-shielding sheets 321. The connecting portions 3221 are generally fixed to the inside of the light-shielding sheet 321 with glue or screws to ensure the stability of the connection.

[0041] The extension portion 3222 is provided with extension pleats 3223 for extending and deforming towards the connecting portions 3221 on both sides. The extension pleats are evenly arranged in the horizontal direction. The extension portion 3222 is made of an elastic opaque material, such as rubber or silicone. The design of the extension pleats 3223 allows the extension portion 3222 to extend and deform towards the connecting portions 3221 on both sides when the light-shielding sheet 321 rotates, ensuring that the elastic extension sheet 322 does not obstruct the rotation of the light-shielding sheet 321, and at the same time covering the gap generated when the two adjacent sets of light-shielding sheets rotate, reducing light leakage.

[0042] Reference Figure 2 and Figure 4 The adjusting frame 31 and the light-shielding plate 321 are configured in a one-to-one correspondence. The adjusting frame 31 includes a first frame 311 fixed to one end of the rotation clearance groove 3231, a second frame 312 disposed at the other end of the rotation clearance groove 3231, and a frame track 313 connecting the first frame 311 and the second frame 312. The first frame 311 has a placement groove 3111 on the side facing the second frame 312 for arranging the light-shielding plate 321, and the state when the light-shielding plate is arranged in the placement groove is defined as the initial state. The second frame 312 has a limiting groove 3112 on the side facing the first frame 311 to restrict the continued rotation of the light-shielding plate 321, and the state when the light-shielding plate 321 is in the placement groove is defined as the maximum rotation state.

[0043] The first frame 311 and the second frame 312 are typically made of metal or plastic. The placement groove 3111 is used to place the light-shielding sheet 321, ensuring the stability of the light-shielding sheet 321 in its initial state. The limiting groove 3112 is used to limit the rotation angle of the light-shielding sheet 321, preventing excessive rotation. The frame track 313 is an arc track used to guide the rotation of the light-shielding sheet 321.

[0044] The light-shielding plate 321 has a rotating wheel 3211 at the end away from the rotating base 323, and the frame track 313 has a track groove for the rotating wheel 3211 to be arranged. The rotating wheel 3211 is usually made of plastic or rubber, with a smooth surface, allowing it to roll smoothly within the track groove. The shape and size of the track groove match the rotating wheel 3211 to ensure the rolling stability of the rotating wheel 3211 within the track groove. The rotating wheel 3211 can also be a wheel with bearings to further reduce rolling resistance.

[0045] Reference Figure 3 , Figure 5 and Figure 6 The cleaning mechanism 4 is located inside the adjusting frame 31. It includes a cleaning transmission component 41 disposed on the rotating shaft 331, a cleaning drive rod 42 connected to the output end of the cleaning transmission component 41, a cleaning mounting plate 43 disposed at the end of the cleaning drive rod 42, a cleaning eccentric rod 44 eccentrically fixed to the cleaning mounting plate 43, and a cleaning tapping rod 45 limited and installed with the cleaning eccentric rod 44.

[0046] The cleaning transmission component 41 is a gear transmission structure, including a driving wheel coaxially fixed to the rotating shaft 331, a driven wheel rotatably mounted on the bottom of the lamp housing bracket 1, and a conveyor belt wound around the two gears. One end of the cleaning drive rod 42 is fixed to the driven wheel, and the cleaning mounting plate 43 is fixed to the other end of the cleaning drive rod 42. In this application, two cleaning drive rods 42 and cleaning mounting plates 43 are provided on a set of rotating shafts 331. The two sets of cleaning mounting plates 43 are connected by a cleaning eccentric rod 44. The cleaning flapping rod 45 is rod-shaped and has a sliding hole 451 through which the cleaning eccentric rod 44 passes. The bottom of the lamp housing bracket 1 has a rotating rod 46 for one end of the cleaning flapping rod 45 to be rotatably mounted, and the other end of the cleaning flapping rod 45 is provided with a flapping part 452.

[0047] The drive shaft 331 rotates the cleaning drive rod 42 through the cleaning transmission component 41. Under the action of the cleaning eccentric rod 44 and the cleaning slapping rod 45, the cleaning slapping rod 45 swings up and down continuously, and the slapping part hits the light-transmitting plate 21, causing the dust adhering to the light-transmitting plate 21 to be knocked off.

[0048] Reference Figure 7 In order to lock or unlock the circumferential limit of the rotating shaft 331 and the light shield 321, this application also includes a locking mechanism 5. The locking mechanism 5 includes a locking push rod 51 that is lifted and mounted on the top of the lamp housing bracket 1, a locking slide rod 52 disposed at the end of the locking push rod 51, and a locking insert rod 53 that is rotatably mounted on the end of the locking slide rod 52.

[0049] The top of the lamp housing bracket 1 has a locking bracket 11 for sliding the locking push rod 51. The locking slide rod 52 is fixed to the bottom of the locking bracket 11, and the locking slide rod 52 corresponds one-to-one with the rotating shaft 331. Specifically, the locking slide rod 52 and the rotating shaft 331 correspond at their middle parts. The locking insert rod 53 is a vertically arranged rod, and its top is slidably mounted on the locking slide rod 52. The locking insert rod 53 slides along an arc, and the center of the arc is coaxial with the rotating shaft 331. The locking push rod 51 has multiple through holes spaced apart along its height direction, and the locking bracket 11 has threaded holes for bolting the locking push rod 51.

[0050] Reference Figure 7 and Figure 8 The rotating base 323 has a first arc hole 3232 corresponding to the locking rod 53, and the light-shielding plate 321 has a locking hole 3213 corresponding to the first arc hole 3232. When the light-shielding plate 321 is in the initial state, the locking hole 3213 and the locking rod 53 correspond to each other in the height direction. The outer wall of the rotating shaft 331 is provided with a first tooth surface 3314 corresponding to the locking hole 3213, and the end of the locking rod 53 has a second tooth surface 531 that mates with the first tooth surface 3314.

[0051] The rotating seat 323 is also provided with two sets of abutment springs 3233 in the first arc hole 3232, and the abutment springs 3233 abut against the opposite sides of the locking rod 53 respectively. The side wall of the locking rod 53 has a limiting block 532 fixed to the end of the abutment spring 3233, and the limiting block 532 and the locking rod 53 slide against each other.

[0052] The implementation principle of this embodiment is as follows: the industrial and mining lamp drives the adjustment cover 32 to rotate through the adjustment drive component 33 in the adjustment mechanism 3, thereby changing the lighting range, reducing the light from shining on non-target areas, and avoiding interference with the visual operations and equipment readings of other workstations; The cleaning mechanism 4 gently taps the surface of the light-transmitting plate 21 to shake off the dust adhering to the light-transmitting plate 21. The locking mechanism 5 controls the locking or unlocking of the rotating shaft 331 and the light-shielding plate 321. When the locking rod 53 is not in the locking hole 3213, the rotation of the rotating shaft 331 will not drive the light-shielding plate 321 to rotate. When the locking rod 53 is inserted into the locking hole 3213, the first tooth surface 3314 and the second tooth surface 531 mesh, and the rotating shaft 331 drives the light-shielding plate 321 to rotate.

[0053] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
