Description

Technical Field

[0001] This utility model belongs to the field of guide rail light technology, and in particular relates to a guide rail light with a quick-change lens. Background Technology

[0002] In museums, art galleries, exhibition halls, and shopping malls (such as clothing, shoes, hats, and handicrafts stores), exhibits or items are frequently changed. Since the size of the exhibits or items may vary, the required beam angle of the lighting fixtures naturally needs to be adjusted. However, most lighting fixtures on the market with a fixed angle currently use screws or clips to fix the lens to the heat sink. If this method is used, when changing the lighting fixtures to different angles to meet the lighting requirements of different exhibits, it is necessary to repurchase lighting fixtures with the appropriate angle. The originally purchased lighting fixtures with a certain angle cannot be used, resulting in waste and increased costs. Utility Model Content

[0003] In view of this, the present invention provides a rail light with a quick-change lens to solve the problem that the lens of the rail light in the prior art is not replaceable or is not easy to replace.

[0004] The technical solution adopted in this utility model is:

[0005] This utility model provides a rail light with a quick-change lens, comprising:

[0006] Lamp body;

[0007] A lens bracket is located inside one end of the lamp body along its length. A locking slide is provided on the outer side wall of the lens bracket, and the locking slide is inclined.

A plurality of the first extensions are circumferentially distributed on the inner sidewall of the lens retaining ring. Each first extension is provided with a locking head at the end away from the lens retaining ring. The locking head cooperates with the locking slide.

[0010] The lamp body rear cover is located at the end of the lamp body away from the lens.

[0011] Preferably, the lens bracket has an anti-detachment part at one end near the locking slide, and the locking slide has a disassembly port and a limiting part at both ends, respectively. When the lens is locked, the locking head is located on the locking slide between the limiting part and the anti-detachment part.

[0012] Preferably, the lens bracket has a connecting hole at its bottom and a lens abutment at one end of the lens bracket away from the connecting hole. Several lens abutments are distributed along the circumferential direction of the lens bracket. The lens has an outer ring at its light outlet, and the end face of the outer ring near the lens abutment abuts the lens abutment.

[0013] Preferably, the lens retaining ring has a protrusion between two adjacent first extensions, and the protrusion contacts the outer peripheral surface of the lens outer ring.

[0014] Preferably, the lens retaining ring is further provided with a pressing surface at the middle position inside, and the pressing surface abuts against the end face of the lens outer ring away from the lens abutment platform.

[0015] Preferably, the lamp body has an aluminum substrate positioning hole, a lamp plate positioning hole and a lens bracket positioning hole at one end near the lens. An aluminum substrate is provided on the aluminum substrate positioning hole, a lamp plate is provided on the lamp plate positioning hole, and a power line is electrically connected to the lamp plate.

[0033] Example 1

[0034] See Figures 1-8 This utility model provides a rail light with a quick-change lens, including a lamp body 1, a lens bracket 2, a lens 3, a lens retaining ring 4, and a lamp body rear cover 5. The lens bracket 2 is located inside one end of the lamp body 1 along its length, and a locking slide 21 is provided on the outer side wall of the lens bracket 2. The locking slide 21 is inclined. The lens 3 is located inside the lens bracket 2, and the lens 3 has an outer lens ring 31 at its light outlet position. The lens retaining ring 4 is located on the lens bracket 2, and a first extension 41 is provided on the lens retaining ring 4. Several first extensions 41 are circumferentially distributed on the inner side wall of the lens retaining ring 4. Each first extension 41 has a locking head 411 at the end away from the lens retaining ring 4, and the locking head 411 cooperates with the locking slide 21. The lamp body rear cover 8 is located at the end of the lamp body 1 away from the lens 3.

[0035] The lens holder 2 has an anti-disengagement part 22 at one end near the locking slide 21. The locking slide 21 has a disassembly port 24 and a limiting part 25 at both ends. When the lens 3 is locked, the locking head 411 is located on the locking slide 21 between the limiting part 25 and the anti-disengagement part 24. In specific operation, first, the lens 3 is placed into the lens holder 2. The first extension 41 on the lens retainer 4 is aligned with the disassembly port 24, and then inserted into the lamp body 1 along the axial direction of the lamp body 1. Then, the lens retainer 411 is... The lens 1 is installed by rotating the ring 4 in the direction that presses the lens 3 until the locking head 411 is located on the locking slide 21 between the limiting part 25 and the anti-dislodgement part 24. The bottom of the lens bracket 2 is provided with a connecting hole 26. At the end of the lens bracket 2 away from the connecting hole 26, there is also a lens abutment platform 23. Several lens abutment platforms 23 are distributed along the circumferential direction of the lens bracket 2. The end face of the outer ring 31 of the lens near the lens abutment platform 23 abuts against the lens abutment platform 23.

[0036] This invention utilizes a tilted locking slide 21 that engages with the locking head 411 of the lens retaining ring 4, allowing the lens 3 to be locked or released simply by rotating the lens retaining ring 4. The inclined structure of the locking slide 21 generates axial clamping force during the rotation of the lens retaining ring 4 in the direction that presses the lens 3, thereby achieving a tight fit between the outer ring 31 of the lens and the lens support 2. This ensures optical positioning accuracy and eliminates the need for screws, enabling quick replacement of the lens 3.

[0037] The lens retaining ring 4 has a protrusion 42 between two adjacent first extensions 41. The protrusion 42 contacts the outer peripheral surface of the lens outer ring 31. The lens retaining ring 4 also has a pressing surface 43 in the middle of its interior. The pressing surface 43 abuts against the end face of the lens outer ring 31 away from the lens abutment platform 23.

[0038] The lamp body 1 has an aluminum substrate positioning hole 11, a lamp board positioning hole 12 and a lens bracket positioning hole 13 at one end near the lens 3. An aluminum substrate 5 is provided on the aluminum substrate positioning hole 11, and a lamp board 6 is provided on the lamp board positioning hole 12. A power cord is electrically connected to the lamp board 6. The bottom of the lens bracket 2 abuts against the aluminum substrate 5 and is fixed through the lens bracket positioning hole 13.

[0039] The lamp body 1 has heat sinks 14 on its inner peripheral wall. A plurality of heat sinks 14 are distributed circumferentially on the inner sidewall of the lamp body 1, and heat dissipation channels 15 are formed between adjacent heat sinks 14.

[0040] The lamp body rear cover 8 has a second extension 81 on one end face near the lamp body 1. Several second extensions 81 are distributed circumferentially along the lamp body rear cover 8. Each second extension 81 has a latching part 811 at the end away from the lamp body rear cover 8. The lamp body rear cover 8 is latched to the lamp body 1 through the latching part 811, which facilitates maintenance and inspection when the lamp malfunctions.

[0041] The lamp body rear cover 8 is further provided with a guide portion 82 between adjacent second extension portions 81, and a ventilation hole 83 is also provided at the end of the lamp body rear cover 8 away from the second extension portion 81. The ventilation hole 83 is connected to the heat dissipation channel 15 to ensure that the heat inside the lamp body can be discharged in time, thereby improving the lamp's service life and product quality.

[0042] The lamp body 1 is also provided with a connecting rod 7 at one end near the rear cover 8 of the lamp body. The connecting rod 7 is rotatably connected to the lamp body 1. The rotatable connection allows for reasonable angle adjustment of the lamp according to different situations, improving the convenience of use for users.
