Description

Technical Field

[0001] This utility model relates to a high-bay industrial and mining lamp, and more particularly to an industrial and mining lamp with an adjustable beam angle. Background Technology

[0002] Compared to traditional industrial and mining lamps, LED industrial and mining lamps have advantages such as high brightness and low power consumption. Due to the varying installation heights required for different application scenarios, it's necessary to use lenses with different beam angles to achieve the desired beam angles for specific needs. Common beam angles include 60°, 90°, and 120°. Most industrial and mining lamps on the market use single-angle lenses, meaning each lens can only achieve one beam angle, resulting in limited functionality, fixed application scenarios, and poor versatility. Some products offer adjustable beam angle solutions through other means, but these often suffer from serious problems such as inadequate waterproofing and inaccurate beam angle control, rendering them impractical. For example, Chinese patent document CN2018210107329 discloses a "variable beam angle industrial and mining lamp," which adjusts the beam angle by rotating the lens to change the distance between the lens and the lamp panel. However, this solution lacks specific features. The lack of a waterproof seal can lead to insufficient waterproof performance. Another similar design uses a rotating lens to adjust the beam angle. However, because the waterproof seal is located on the outer circumference of the lens, this design causes a series of problems. For example, if the seal is too large, the pressure on the side walls is too high, making it difficult to rotate and adjust the lens. It can also cause the lens to deform due to compression, resulting in an inaccurate beam angle. Conversely, if the seal is too small, the waterproof performance is poor, and the entire lamp fails the IP65 waterproof test. Finding an accurate length for the seal is difficult. Furthermore, there are problems with the manufacturing process. Because the seal is relatively soft and easily stretched, it is difficult to ensure the uniformity of the contact surface during assembly, further affecting waterproof performance. Therefore, from multiple perspectives, this rotating lens design has inherent shortcomings. It is difficult to consistently guarantee the waterproof rating throughout the entire lamp, and the beam angle is inaccurate, failing to meet customer requirements. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an industrial and mining lamp with an adjustable beam angle. It innovatively designs through holes on both the heat sink and the lens, and adopts a combination structure design of double pressure plate and semi-open sealing ring to give the industrial and mining lamp stable and reliable waterproof performance. The lens is designed with a straight stroke positioning hole, which, together with the spring screw installed on the side of the heat sink, achieves precise beam angle control. At the same time, the industrial and mining lamp has dimming and color adjustment functions, which can meet the customer's requirements for different beam angles, different power and different color temperatures.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: This utility model discloses an adjustable beam angle industrial and mining lamp, the main structure of which includes a heat sink, an adjustable lens, a sealing ring, an upper pressure plate, a lower pressure plate, a driving power supply, a lamp board, a waterproof connector, a screw cap, a breather, a lifting ring, and several screws, etc. The heat sink is integrally formed and has a through hole near the outer circumference. After the through hole is matched and positioned with the upper pressure plate, a screw is used to pass through the through hole from the outer side of the heat sink and lock the upper pressure plate. The upper edge of the sealing ring is between the heat sink and the upper pressure plate. The adjustable lens has a through hole near the outer circumference. After the through hole is matched and positioned with the lower pressure plate, a screw is used to pass through the through hole from the outer side of the adjustable lens. After the second hole is tightened, the lower pressure plate is locked. The lower edge of the sealing ring is between the adjustable lens and the lower pressure plate. The adjustable lens has several stroke positioning blocks, each with a row of stroke positioning holes. The stroke positioning holes cooperate with several spring screws installed on the side of the heat sink to precisely control the distance between the adjustable lens and the lamp plate, thereby adjusting the beam angle of the entire lamp. The sealing ring has a semi-open cross-section, divided into an upper edge, a lower edge, and a middle telescopic part. The upper pressure plate and the lower pressure plate are installed in the middle of the opening. After being locked by screws nine and ten, the seal between the heat sink and the adjustable lens is achieved. The sealing ring is made of a relatively soft material and can be extended and retracted through the reserved middle telescopic part to achieve the mobility between the heat sink and the adjustable lens.

[0005] The radiator is integrally molded and has screw posts 1, 2, and 3 on the inner surface and screw posts 4, 5, 6, and 7 on the back, along with heat dissipation ribs, a protrusion, a wiring hole, a lifting eye hole, a breather hole, and a sealing groove. Several through holes 1 are located on the outer circumference of the back of the radiator. After the through holes 1 are positioned and matched with screw posts 9 on the upper pressure plate, screws 9 pass through the through holes 1 from the outside of the radiator and lock the screw posts 9 on the upper pressure plate, thereby pressing the upper edge of the sealing ring between the radiator and the upper pressure plate, achieving a seal after locking. Screw post 1 is used to fix lamp board 1, screw post 2 is used to fix the grounding wire, heat dissipation ribs are used to dissipate heat during lamp operation, and the protrusion is used to fix the spring screw. There are two sets of wiring holes; one set, after tapping and adding a waterproof connector, is used to pass the power output wire of the driver power supply. The waterproof connector enhances the waterproofness of the entire lamp and the tensile strength of the power output wire, which connects to lamp board 1. The other set is for pre-installing the induction output wire. The following options are provided: Through holes or blind holes can be selected as needed. The breather hole is used to fix the breather, which provides waterproofing and breathability. Screw post five is used to fix the drive power supply. In embodiment three, screw post seven is used to fix the mounting bracket. In embodiment four, screw post three is used to fix the dimming and color-tuning circuit board, and screw post six is ​​used to fix the lamp holder. The sealing groove is used to position the sealing ring two. In embodiment five, screw post three is used to fix the dimming and color-tuning circuit board, and screw post four is used to fix the pressure plate. The lifting eye hole is used to directly fix the lifting eye for easy installation. To ensure the versatility of the heat sink under various installation methods, the screw posts and other features required in various embodiments are integrated into one heat sink, but this increases material costs. If cost is a consideration, the features of the heat sink can be designed separately according to actual needs. In terms of shape, in addition to being circular, the heat sink can also be made square as in embodiment six. The beam angle adjustment principle and waterproofing principle are the same as in other embodiments.

[0006] Preferably, a through hole is designed on the heat sink, and the upper pressure plate is locked after passing through the through hole from the back of the heat sink with screw nine. This structural assembly method is conducive to the subsequent maintenance of the product, such as the quick replacement of the lamp board, which greatly shortens the maintenance time.

[0007] When the design of the through hole 1 of the radiator is changed to a blind hole on the inner wall of the radiator, certain structural changes need to be made to the upper and lower pressure plates to achieve the same waterproof function. However, this solution is not conducive to the subsequent maintainability of the product. When the lamp board 1 needs to be replaced, the maintenance time is greatly extended and the process is not very efficient.

[0008] The adjustable lens is integrally injection molded. It has several travel positioning blocks, through holes, an optical surface, a boss, and reinforcing ribs. Each travel positioning block has a row of travel positioning holes on its outer side. These holes, fixed by spring screws, control the distance between the optical surface and the lamp panel, thus adjusting the beam angle of the entire lamp. An angle indicator is located on the side of each travel positioning block, displaying the actual beam angle of the adjustable lens at different travel positioning hole positions for easy customer identification. Both the inner and outer sides of each travel positioning block have hand grips, allowing customers to easily adjust the adjustable lens up and down. The number of travel positioning blocks can be adjusted as needed, such as from four to eight or other numbers. After the through holes on the edge of the adjustable lens align with the screw posts on the lower pressure plate, the screws pass through the through holes and lock the screw posts on the lower pressure plate. The lower edge of the sealing ring is between the adjustable lens and the lower pressure plate; tightening achieves a seal. The middle of the adjustable lens... Optical surface 1 works in conjunction with LED beads 1 to achieve the designed light emission angle. The optical surface can be made into a ring, or into a bead shape as in embodiment 2, or into other shapes as needed, such as the square shape in embodiment 6. The inner side of the adjustable lens 1 has a boss 1, with screw post 8 and internal thread 1 on the boss 1. One of the internal threads of the boss 1 is a reserved position for the assembly of the functional expansion module, which can be expanded into the sensor scheme of embodiment 2 and embodiment 3. In the normal state, it is tightened with a screw cap. In embodiment 2, screw post 8 is used to install the adapter circuit board between the sensor and the lamp board 1. In embodiment 3, screw post 8 is used to install the anti-rotation plate that fixes the standard zhaga interface. In embodiment 4 and embodiment 5, when the external independent driving power supply is cancelled and replaced with an internal one, the driving power supply is integrated into the lamp board, forming the form of lamp board 3. The diameter of the boss 1 in the middle of the adjustable lens 1 is enlarged to form the form of adjustable lens 3, in order to accommodate more components and form a DOB power supply scheme, while reducing costs.

[0009] The sealing ring is semi-open, consisting of an upper edge, a lower edge, and a middle telescopic part. There are holes in the middle of the planes of the upper and lower edges, through which screw posts nine of the upper pressure plate and ten of the lower pressure plate can pass, respectively. The upper and lower pressure plates are assembled in the middle of the semi-open section. The upper edge of the sealing ring is pressed against the inner wall of the radiator by the upper pressure plate, and the lower edge of the sealing ring is pressed against the adjustable lens one by the lower pressure plate, thus achieving a seal between the radiator and the adjustable lens one. The middle telescopic part is located between the upper and lower edges of the sealing ring. Because the sealing ring is made of soft material, it can extend and retract through the middle telescopic part, thereby adjusting the distance between the radiator and the adjustable lens one. The shape of the middle telescopic part is not limited to an arc shape; it can also be made into other shapes such as a V-shape.

[0010] Preferably, the sealing ring is semi-open, with the opening facing outwards. The outward-facing opening is beneficial for the production of the sealing ring component, the assembly of the entire lamp, and the maximization of the light-emitting surface.

[0011] The upper pressure plate has a screw post nine on its flat surface. After the screw post nine passes through the upper edge hole on the sealing ring, it is positioned and matched with the through hole one on the radiator. Then, after the screw nine passes through the through hole one on the outside of the radiator, it cooperates with the screw post nine on the upper pressure plate to lock it. While locking, the upper edge of the sealing ring is pressed against the radiator.

[0012] The lower pressure plate has a screw post 10 on its flat surface. After the screw post 10 passes through the lower edge hole on the sealing ring, it is positioned and matched with the through hole 2 of the adjustable lens 1. Then, after the screw post 10 passes through the through hole 2 of the adjustable lens 1, it cooperates with the screw post 10 on the lower pressure plate to lock it. At the same time as locking, the lower edge of the sealing ring is pressed against the adjustable lens 1. The lower pressure plate and the upper pressure plate have the same structure and the same process. They are both integrally formed.

[0013] When the upper and lower pressure plates are made into a split type as in Embodiment Six, their shape becomes a square with a hexagonal stepped hole. At the same time, an independent hexagonal rivet nut is added. The hexagonal rivet nut plays the same role as screw post nine and screw post ten, thereby achieving the same waterproof effect. The hexagonal rivet nut is a common part on the market.

[0014] Preferably, the upper and lower pressure plates are manufactured using an integral die-casting process, which helps to enhance structural strength, ensure the tight sealing ring, and achieve more stable waterproof performance.

[0015] When the upper and lower pressure plates are made using injection molding, plastics with relatively good hardness and rigidity, such as nylon, should be used first to ensure structural strength and thus achieve better waterproofing.

[0016] The driving power supply has a sealing cover, a DIP switch, a power input line, a power output line, an external control line, and a sensor output line. The power output line passes through the inlet hole on the heat sink and is pressed onto the heat sink by a waterproof connector. The driving power supply is fixed to the screw post five on the back of the heat sink by screw five. The power output line is connected to the lamp board one. The driving power supply has a reserved sensor output line, which is connected to the sensor control expansion module or intermediate adapter.

[0017] The lamp board has one LED chip, one wire hole, one lamp board hole, and other components. The screw hole avoids the optical surface area in the middle of the adjustable lens. After the lamp is installed, there are no obvious screw assembly marks on the optical surface, which improves the aesthetics of the lamp. After eliminating the external power supply, the power supply is built-in, and other components are integrated on the lamp board to make a DOB power supply solution like the lamp board three. At the same time, it can reduce costs. The LED chip can be arranged with at least two color temperatures. After the screw passes through the lamp board hole, the lamp board is fixed to the screw post of the heat sink and is close to the inner surface of the heat sink. The power output line passes through the wire hole and is soldered to the lamp board.

[0018] In Examples 1 to 5, the product is circular. The principle of this technical solution is not limited by the shape. The product can also be made into a square shape as in Example 6. The principle of the technical solution is the same.

[0019] The biggest advantage of this technical solution is that the industrial and mining lamp has the function of adjusting the beam angle, and at the same time has more stable and reliable waterproof performance.

[0020] Compared with the prior art, the advantages of this utility model are:

[0021] (1) In this technical solution, the lens of the industrial and mining lamp can be moved vertically up and down. By controlling the distance between the lens and the lamp panel, the beam angle of the lamp can be adjusted. This allows one lens to achieve multiple beam angles, adapt to various practical scenarios, and is more convenient to adjust. The beam angle control is also more precise.

[0022] (2) This technical solution can achieve more stable and reliable waterproof performance while realizing beam angle adjustment. Compared with other solutions on the market, it has better waterproof performance.

[0023] (3) Compared with the common solutions on the market, this technical solution does not show obvious screw marks on the front of the lens optical surface. The screw marks are hidden on the inner and outer edges, making the overall appearance of the lamp more beautiful.

[0024] (4) This solution has a high degree of technical integration and strong expandability, and can be compatible with more functions. It also has reserved installation positions for microwave modules, infrared modules, standard zhaga interfaces, etc. Attached Figure Description

[0080] Example 1

[0081] like Figures 1-22As shown, the main structure of this adjustable beam angle industrial and mining lamp includes a heat sink 10, an adjustable lens 11, a sealing ring 12, an upper pressure plate 13, a lower pressure plate 14, a driving power supply 15, a lamp plate 16, a waterproof connector 17, a screw cap 18, a breather 19, and a lifting ring 20. The heat sink 10 is integrally formed and has a through hole 1100 near its outer circumference. After the through hole 1100 is matched and positioned with the screw post 1301 on the upper pressure plate 13, screw 29 is used to open the back of the heat sink 10. After passing through the through hole 1000, the screw post 9 1301 of the upper pressure plate 13 is locked and fixed. The upper edge 1200 of the sealing ring 12 is between the heat sink 10 and the upper pressure plate 13. The adjustable lens 11 has a through hole 2 1100 near its outer circumference. After the through hole 2 1100 is matched and positioned with the screw post 1401 on the lower pressure plate 14, the screw post 1401 of the lower pressure plate 14 is locked and fixed by the screw 30 passing through the through hole 2 1100 from the outside of the adjustable lens 11. The adjustable lens 11 and the lower pressure plate 14 are connected by the lower edge 1201 of the sealing ring 12. The adjustable lens 11 has a travel positioning hole 1106 on its travel positioning block 1101. The travel positioning hole 1106, in conjunction with a spring screw 31 mounted on the side of the radiator 10, precisely controls the distance between the adjustable lens 11 and the lamp plate 16, thereby adjusting the overall lamp beam angle. Each row of travel positioning holes 1106 has several holes; holes at different positions correspond to different beam angles. The sealing ring 12 has a semi-open cross-section. The upper edge 1200 has an upper edge hole 1203, and the lower edge 1201 has a lower edge hole 1204. The middle telescopic part 1202 can extend and deform. After the pressure plate 13 and the lower pressure plate 14 are installed in the middle of the semi-open 1205, the seal between the radiator 10 and the adjustable lens 11 is achieved. The sealing ring 12 is made of relatively soft material and can extend and retract through the reserved middle telescopic part 1202 to achieve the mobility between the radiator 10 and the adjustable lens 11.

[0082] like Figures 3-22 , Figure 29 , Figures 39-40 , Figure 41As shown, the radiator 10 is integrally formed, with screw posts 1001, 1002, and 1003 on the inner surface, and screw posts 1004, 1005, 1006, and 1007 on the back, as well as heat dissipation fins 1008, protrusions 1009, a cable inlet 1010, a lifting eye hole 1011, a breather hole 1012, and a sealing groove 1013. The outer circumference of the back of the radiator 10 has several through holes 1000. After the through holes 1000 are matched and positioned with screw posts 1301 on the upper pressure plate 13, screws 29 are inserted... After the heat sink 10 passes through the through hole 1000 on the outside, the screw post 1301 of the upper pressure plate 13 is tightened. The upper edge 1200 of the sealing ring 12 is between the heat sink 10 and the upper pressure plate 13. After tightening, a seal is achieved. Screw post 1001 is used to fix the lamp board 16. Screw post 2 1002 is used to fix the grounding piece on the power output line 1503. Screw post 5 1005 is used to fix the driver power supply 15. The heat dissipation fin 1008 is used to dissipate the heat when the lamp is working. The protrusion 1009 is tapped on the side and used to fix the spring screw 31. The spring screw 31 is used to position the adjustable lens. The distance between lamp board 11 and lamp panel 16 is such that there are two sets of inlet holes 1010. One set passes through the power output line 1503 of the driver power supply 15, which is soldered to lamp board 16. The other set is reserved for the induction output line 1505. It can be made into a through hole or a blind hole as needed. After tapping, the inlet hole 1010 is used to fix the waterproof connector 17. The waterproof connector 17 is divided into a lower part 1700 and an upper part 1701. The lower part 1700 and the upper part 1701 have their own waterproof structure. After tightening, they can play a waterproof role and enhance the power output line 1503. The tensile strength is provided. The respirator hole 1012 is used to fix the respirator 19. The respirator 19 has a waterproof and breathable function. In embodiment three, screw post seven 1007 is used to fix the L-shaped bracket 38. In embodiment four, screw post three 1003 is used to fix the dimming and color-tuning circuit board 42. The sealing groove 1013 is used to fix the sealing ring two 47. Screw post six 1006 is used to fix the lamp holder 43. In embodiment five, screw post three 1003 is used to fix the dimming and color-tuning circuit board 42. The lifting eye hole one 1011 is used to fix the lifting eye 20. Screw post four 1004 is used to fix the pressure plate 48.

[0083] As described above, in order to meet the versatility of the radiator 10 under various installation methods, features such as screw posts required by various embodiments are integrated into one radiator, but this will increase material costs. If cost is taken into consideration, the features of the radiator 10 can be classified according to the needs of different embodiments. In terms of shape, in addition to being made into a circle, the radiator 10 can also be made into a square as in Embodiment Six. The beam angle adjustment principle and waterproof principle are the same as those of other embodiments.

[0084] like Figures 3-18 , Figure 24 , Figure 28 , Figure 33 , Figure 40 , Figure 44 As shown, the adjustable lens 11 is integrally injection molded. The adjustable lens 11 has a through hole 1100, a travel positioning block 1101, an optical surface 1102, a boss 1103, and a reinforcing rib 1104. Each travel positioning block 1101 has a guide groove 1105 on its outer side, and each guide groove 1105 is designed with a row of travel positioning holes 1106. After being fixed by spring screws 31, the travel positioning holes 1106 are used to control the distance between the optical surface 1102 and the lamp panel 16, thereby adjusting the beam angle of the entire lamp. Different positions of the holes correspond to different beam angles. An angle indicator 110 is located on the side of the travel positioning block 1101. 7. The angle indicator 1107 can display the actual beam angle of the adjustable lens 11 at different positions of the travel positioning hole 1106, which is convenient for customers to identify. The travel positioning block 1101 has an inner hand grip groove 1110 on the inside and an outer hand grip groove 1111 on the outside, which is convenient for customers to reach in and adjust up and down. After the through hole 1100 on the edge of the adjustable lens 11 is positioned and matched with the screw post 1401 on the lower pressure plate 14, the screw 30 passes through the through hole 1100 and locks the lower pressure plate 14. The lower edge 1201 of the sealing ring 12 is between the adjustable lens 11 and the lower pressure plate 14. After pressing, a seal is achieved. The reinforcing rib 1104 helps to enhance the protection. The adjustable lens 11 has an optical surface 1102 in the middle that works with the LED bead 1601 to achieve the designed optical angle. The optical surface can be made into a ring shape as in Embodiment 1 or a bead shape as in Embodiment 2, or other shapes as needed. The adjustable lens 11 has a boss 1103 on its inner side, with a screw post 1108 and an internal thread 1109. In normal conditions, the internal thread 1109 is tightened with the cap 18 to achieve a seal. The internal thread 1109 is a reserved position for a function expansion interface or an adapter plate. In Embodiment 2, the internal thread 3204 is used to fix the sensor 35. With its own waterproof structure, it is a standard component on the market. Screw post 11 3205 and screw 28 are used to fix the adapter circuit board 34 between sensor 35 and lamp board 2 33. In embodiment 3, internal thread 1109 is used to fix the standard zhaga interface 37, and screw post 8 1108 and screw 28 are used to fix the anti-rotation plate 36 that matches the standard zhaga interface 37. In embodiments 4 and 5, when the external driving power supply 15 is removed and replaced with an internal one, the power supply is integrated on lamp board 3 46. The diameter of the boss 3 4503 in the middle of the adjustable lens 3 45 is slightly larger than that of boss 1103 to accommodate the components required by the new power supply scheme.

[0085] like Figures 9-10 , Figure 19-22As shown, the sealing ring 12 is a semi-open type. The sealing ring body 12 has an upper edge 1200, a lower edge 1201, and a middle telescopic part 1202. The upper edge 1200 has an upper edge hole 1203 on its plane, and the lower edge 1201 has a lower edge hole 1204 on its plane. The upper edge hole 1203 can pass through the screw post 1301 on the plane of the upper pressure plate 13, and the lower edge hole 1204 can pass through the screw post 1401 on the lower pressure plate 14. After the upper pressure plate 13 and the lower pressure plate 14 are assembled in the middle of the opening of the sealing ring 12, the sealing ring 12... The upper edge 1200 is pressed against the inner wall of the radiator 10 by the upper pressure plate 13, and the lower edge 1201 of the sealing ring 12 is pressed against the inner wall of the adjustable lens 11 by the lower pressure plate 14, thereby achieving a seal between the radiator 10 and the adjustable lens 11. The middle telescopic part 1202 is located between the upper edge 1200 and the lower edge 1201 of the sealing ring 12. Since the sealing ring 12 is made of soft material, it can be telescopically moved through the middle telescopic part 1202, thereby achieving the adjustment of the distance between the radiator 10 and the adjustable lens 11.

[0086] Preferred, such as Figure 10 As shown, the sealing ring 12 has a semi-open cross-section with the opening facing outwards. The outward-facing opening is beneficial for the production of this part, the assembly of the entire lamp, and the maximization of the light-emitting surface. In addition to being made into an arc shape, the middle telescopic part 1202 can also be made into other shapes such as a V-shape.

[0087] like Figures 11-12 , Figure 19-22 As shown, the upper pressure plate 13 is composed of an upper pressure plate plane 1300 and a screw post 1301. The upper pressure plate plane 1300 presses the upper edge 1200 of the sealing ring 12. After the screw post 1301 passes through the upper edge hole 1203 on the sealing ring 12, it is positioned and matched with the through hole 1000 on the radiator 10. Then, the screw 29 passes through the through hole 1000 from the outside of the radiator 10 and locks with the screw post 1301 of the upper pressure plate 13. At the same time as locking, the upper edge 1200 of the sealing ring 12 is pressed onto the radiator 10.

[0088] like Figure 13 , Figure 19-22 As shown, the lower pressure plate 14 consists of a lower pressure plate plane 1400 and a screw post 1401. The lower pressure plate plane 1400 presses the lower edge 1201 of the sealing ring 12. After the screw post 1401 passes through the lower edge hole 1203 on the sealing ring 12, it is positioned and matched with the through hole 1100 of the adjustable lens 11. Then, the screw 30 passes through the through hole 1100 of the adjustable lens 11 and locks with the screw post 1401 on the lower pressure plate 14. At the same time as locking, the lower edge 1201 of the sealing ring 12 is pressed against the inner wall of the adjustable lens 11. The lower pressure plate 13 and the upper pressure plate 14 have the same structure and are integrally formed. The preferred material is die-cast aluminum alloy, and the second choice is engineering plastic with good rigidity, such as nylon.

[0089] like Figures 11-13 , Figure 19-22 , Figures 48-50 As shown, when the upper pressure plate 13 and the lower pressure plate 14 are made into a split type as in Embodiment Six, their shape becomes a square with hexagonal stepped holes, such as the square upper pressure plate 53 and the square lower pressure plate 54. Simultaneously, independent hexagonal rivet nuts 55 are added. The hexagonal rivet nuts 55 play the same role as screw post nine 1301 and screw post ten 1401, and can achieve the same waterproof effect.

[0090] like Figures 11-13 , Figure 20 As shown, preferably, the upper pressure plate 13 and the lower pressure plate 14 are integrally die-cast, which helps to enhance the structural strength, ensure the tight sealing ring 12, and achieve more stable waterproof performance.

[0091] When considering cost, when the upper pressure plate 13 and the lower pressure plate 14 are made using injection molding, the first consideration is to use plastics with relatively good hardness and rigidity, such as nylon, to ensure structural strength.

[0092] like Figures 3-4 , Figure 14 , Figure 19-22 , Figure 28 , Figure 33 As shown, the drive power supply 15 has a sealing cover 1500, a DIP switch 1501, a power input line 1502, a power output line 1503, an external control line 1504, a sensor output line 1505, and a lifting eyelet 1506. After tapping the inlet hole 1010, the power output line 1503 passes through the inlet hole 1010 and is pressed onto the heat sink 10 by the waterproof connector 17. The drive power supply 15 is fixed to the screw post 1005 on the back of the heat sink 10 by screw 25. Input line 1502 is connected to AC power for power supply. Power output line 1503 is soldered to lamp board 16. External control line 1504 and induction output line 1505 are reserved on the drive power supply 15. External control line 1504 is connected to an external controller. Induction output line 1505 is connected to the adapter circuit board 34 or standard Zhaga interface 37. After setting the power and color temperature of DIP switch 1501, the sealing cover 1500 is tightened. Hanging ring hole 1506 is used to install hanging ring 20.

[0093] like Figure 15 , Figure 19-22As shown, the aluminum substrate 1600 of the lamp board 16 has LED beads 1601, wire holes 1602, lamp board holes 1603 and other components. The screw holes 1603 avoid the optical surface 1102 area in the middle of the adjustable lens 11. After the lamp is assembled, there are no obvious screw assembly marks on the optical surface 1102, which improves the aesthetics of the lamp. When the external power supply is removed, the power supply is built-in and integrated into the lamp board. The LED beads 1601 can be arranged with at least two color temperatures. After the screw 21 passes through the lamp board hole 1603, the lamp board 16 is fixed to the screw post 1001 of the heat sink 10. The power output line 1503 passes through the wire hole 1602 and is soldered to the lamp board 16.

[0094] like Figure 16 As shown, the waterproof connector 17 is divided into a lower part 1700 and an upper part 1701. The waterproof connector 17 comes with two types of sealing rings, which are common parts on the market.

[0095] like Figure 17 As shown, the cap 18 has an external thread 1800, an O-ring 1801, an anti-slip rib 1802, and a cross groove 1803. The external thread 1800 is rotated and matched with the internal thread 1109 on the adjustable lens 11 to tighten and fix it. The O-ring 1801 at the bottom of the external thread 1800 ensures the waterproofness between the contact surface with the adjustable lens 11. The anti-slip rib 1802 is designed for the convenience of customers to manually tighten the cap 18. The cross groove 1803 is reserved for customers to tighten it with screwdrivers and other tools.

[0096] like Figure 3 , Figures 18-22 As shown, the respirator 19, the hanging ring 20, and the spring screw 31 are common parts available on the market. The spring screw 31 can be selected as a plunger screw type or a glass ball screw type as needed, and has an internal spring mechanism.

[0097] Example 2

[0098] like Figures 23-28As shown, Embodiment 2 is similar to Embodiment 1 in overall design, except that Embodiment 2 adds a sensing function and uses a different lens shape, correspondingly employing a different lamp panel. This embodiment uses an adjustable lens 32 with a bead-shaped shape. This lens has a through hole 3200, a travel positioning block 3201, an optical surface 3202 with a bead shape, and a boss 3203. The main difference between the adjustable lens 32 and the adjustable lens 11 is the shape of the optical surface. The optical surface 3202 has a bead shape. The through hole 3200 has the same function as the through hole 1100, and is fixed by the screw 30 after matching with the screw post 1401 on the lower pressure ring 14. The travel positioning block 3201 is the same as the travel positioning block 110. 1. With identical functions, boss 2 3203 and boss 1 1103 have the same function. For the adjustable lens 2 32 with matching bead shape, a lamp board 2 33 with different LED arrangement is adopted. The aluminum substrate 3300 of lamp board 2 33 has LED beads 2 3301. At the same time, in embodiment 2, the sensing function is added by adding sensor 35. Sensor 35 is a common component on the market. Sensor 35 is connected to the adapter circuit board 34 to achieve the purpose of controlling lamp board 2 33. Screw 8 28 passes through the fixing hole 1 3400 of the adapter circuit board 34 and is fixed on the screw post 11 3205 of the adjustable lens 2 32. Sensor 35 is screwed on the internal thread 2 3204. The contact on sensor 35 makes contact with the ring circuit 3401 on the adapter circuit board 34 for conductivity.

[0099] Example 3

[0100] like Figure 4 , Figure 7 , Figures 29-33As shown, Embodiment 3 is similar to Embodiment 1 in its overall scheme. The difference is that Embodiment 3 adds a standard zhaga module 37, and the entire lamp adopts a new installation method. The standard zhaga module 37 is compatible with multiple functional expansion modules. The standard zhaga module 37 has an external thread at its top, which matches the internal thread 1109 of the adjustable lens 11. To prevent the standard zhaga module 37 from becoming loose and affecting waterproofing, an anti-rotation plate 36 is added to fix the standard zhaga module 37. The anti-rotation plate 36 has an anti-rotation limiting hole 3600 and a fixing hole 3601. When the standard zhaga interface 37 is tightened to a certain extent to achieve waterproofing, the anti-rotation limiting hole 3600 is matched with the external thread of the standard zhaga interface 37, and a screw 28 is passed through the anti-rotation plate. The standard Zhaga interface 37 is fixed to the screw post 1108 of the adjustable lens 11 via the second fixing hole 3601 of 36. In embodiment three, the industrial and mining lamp is fixed by a bracket. The L-shaped bracket 38 is fixed to the screw post 1007 of the radiator 10 after the screw 27 passes through the bracket hole 3800. The U-shaped bracket 39 is fixed to the L-shaped bracket 38 via the screw and nut combination 40 passing through the bracket hole 3801 and the bracket hole 3901. The tilt angle between the U-shaped bracket 39 and the L-shaped bracket 38 is controlled by the screw and nut combination 41 passing through the bracket hole 3802 and the bracket hole 3902. There are several bracket holes 3802, and the center of each bracket hole 3802 is on the same pitch circle. The bracket hole 4904 is the customer's installation hole.

[0101] Example 4

[0102] like Figures 4-5 , Figure 35 , Figures 34-40As shown, unlike Embodiments 1, 2, and 3, Embodiment 4 adopts a standard lamp holder 44 installation method, expanding the application scenarios. The driver power supply 15 is eliminated and integrated into the lamp board 46, using a DOB power supply solution. The dimming and color-tuning circuit board 42 is fixed to the screw post 1003 after passing through the fixing hole 4200 with screws 23. The dimming and color-tuning circuit board 42 has two dimming and color-tuning switches 4201, one for dimming and the other for color-tuning. The lower part of the lamp holder 43 has... The lamp holder 43 is fixed to the screw post 1006 of the heat sink 10 after passing through the lamp holder fixing hole 4300 with screw 26. The upper part of the lamp holder 43 has an external thread 4301 to match the standard lamp holder 44. The standard lamp holder 44 can be of model E40, E39, etc. There is a small hole 4302 in the middle of the top of the lamp holder 43 for the input wire to pass through, which is used to pass through the power wire soldered to the lamp board 46. The lamp holder 43 has an internal pressure rib 4303 inside, which presses the sealing ring 47 into the seal of the heat sink 10. To enhance waterproofing, the adjustable lens 45 has a through hole 4500, a travel positioning block 4501, an optical surface 4502, and a boss 4503. Compared to the adjustable lens 11, the main difference is that the boss 4503 is larger than the boss 1103, to accommodate components for the new power supply solution and meet the requirements of the DOB power supply solution. The through hole 4500 has the same function as the through hole 1100, and is screwed into place after matching with the screw post 1401 on the lower pressure ring 14. The wire 30 is fixed. The stroke positioning block 3 4501 has the same function as the stroke positioning block 1101. The shape of the optical surface 3 4502 is ring-shaped and similar to that of the optical surface 1102, only differing in size. The lamp board 3 46 has an added component 4600 in the middle to make the power supply solution a DOB power supply solution. In addition to making the power supply solution a DOB power supply solution built into the lamp board 46, the power supply solution can also be made into an independent drive power module and installed in the cavity of the lamp holder 43, but the cost will increase, which will not be elaborated here.

[0103] Example 5

[0104] like Figures 4-5 , Figure 35 , Figures 41-45As shown, unlike the standard lamp holder 44 installation method in Embodiment 4, Embodiment 5 uses a hanging ring directly mounted on the heat sink 10. The power supply is also designed as a DOB power supply, integrated into the lamp board 46. A component 4600 is added to the middle of the lamp board 46 to make the power supply a DOB power supply. The dimming and color-tuning circuit board 42 is fixed to the screw post 1003 after passing through the fixing hole 4200 with screw 23. The dimming and color-tuning circuit board 42 has two dimming and color-tuning switches 4201, one for dimming and the other for color-tuning. The power cable passes through the wire hole 4800 on the wire clamping cover 48, is fitted with a sealing plug 49, and then through the wire inlet hole 1010 on the heat sink 10. Finally, screw 24 passes through the clamping hole 4801 and is locked to the screw post 1004 of the heat sink 10. This solution reduces the overall cost of the lamp, but the heat dissipation effect and lifespan parameters are not as good as those of an independent drive power supply.

[0105] Example 6

[0106] In Examples 1 to 5, the overall shape of the product is circular. However, this technical solution is not limited to the shape. Figures 46-51 As shown, the overall shape of this embodiment six is ​​square. The technical principle of the square version is the same as that of the round version, only the shape is different. By analogy, the square heat sink 50 is the same as the heat sink 10, the square adjustable lens 51 is the same as the adjustable lens 11, the square sealing ring 52 is the same as the sealing ring 12, and the combination of the square upper pressure plate 53 and the hexagonal rivet nut 55 is the same as that of the upper pressure plate 13. The square upper pressure plate 53 is designed with a hexagonal stepped hole 5300. The hexagonal stepped hole 5300 and the hexagonal rivet nut 55 are designed together. The hexagonal edge 5500 on the upper part is matched and fixed. The combination of the square lower pressure plate 54 and the hexagonal rivet nut 55 is the same as that of the lower pressure plate 14 in principle. The square lower pressure plate 54 is designed with a hexagonal stepped hole 2 5400. The hexagonal stepped hole 2 5400 matches and is fixed with the hexagonal edge 5500 on the hexagonal rivet nut 55. The hexagonal rivet nut 55 plays the same role as screw post 9 1301 and screw post 10 1401, achieving the same waterproof effect. The hexagonal rivet nut 55 is a common part on the market. The square light plate 56 is the same as the light plate 1 16 in principle.

[0107] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features of different embodiments are embodied in the same drawing, it can be regarded that the drawing also discloses the combination examples of the various embodiments involved.

[0108] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.

When the external power supply is removed, the power supply is built-in and integrated into the lamp board, forming a DOB power supply solution.
