[0047] Specifically, the outer lamp body 2 of the present embodiment is an injection-molded plastic part, a receiving cavity 20 is provided inside the outer lamp body 2 , the inner lamp body 1 is installed in the receiving cavity 20 , and is rotatably connected to the outer lamp body 2 through the adjustment assembly 3 .

[0048] The inner lamp body 1 is a metal part, which can be formed by cutting technology, and is used to guide the light emission of the lamp head and shield the light. A groove body 11 is opened on the inner lamp body 1. The inner lamp body 1 includes a light shielding side portion 101 with two planes on both sides, and an arc portion 102 located between the light shielding side portions 101 on both sides. In the structure in which the inner lamp body 1 and the outer lamp body 2 are rotatably connected, the inner lamp body 1 is connected to the outer lamp body 2 through the light shielding side portion 101, and the arc portion 102 can slide in and out of the accommodating cavity 20, so that the position between the inner lamp body 1 and the outer lamp body 2 changes. The groove body 11 is opened on the light shielding side portion 101.

[0049] The adjustment assembly 3 includes a first adjustment member 31, a second adjustment member 32 and a spring 33. The first adjustment member 31 is an injection-molded plastic member, and is provided with a slide groove 311, a clamping groove 312, a first slide portion 313 and a second slide portion 314. The slide groove 311 is generally arc-shaped, and has an upper groove side wall and a lower groove side wall. The first slide portion 313 is arranged on the upper groove side wall of the slide groove, and the first slide portion 313 is an arc-shaped structure as a whole; the second slide portion 314 is arranged on the lower groove side wall of the slide groove, and the second slide portion 314 is only partially an arc-shaped structure, because the first adjustment member 31 is provided with a platform 315 in the middle, and the platform 315 is connected to the second slide portion 314, but is not completely an arc-shaped structure.

[0050] It should be noted that the spring piece 33 of this embodiment is a metal piece, which can be a stainless steel spring piece. The spring piece 33 is embedded and installed in the first adjusting member 31, and the spring piece is provided with a third sliding portion 330. The third sliding portion 330 is arc-shaped and protrudes from the platform 315, and is spliced ​​with the second sliding portion 314 to form an arc-shaped structure. The second sliding portion 314 and the third sliding portion 330 are located at the lower side of the slide groove 311, and the first sliding portion 313 is located at the upper side of the slide groove 311; therefore, the second sliding portion 314 and the third sliding portion 330 are arranged in a direction opposite to the first sliding portion 313.

[0051] The second adjusting member 32 is fixedly connected to the outer lamp body 2. The second adjusting member 32 of this embodiment is also an injection-molded plastic member, and its material is nylon plastic material, which has certain plastic deformation performance.

Specifically, the first sliding portion 313 is connected to one side of the guide rail 320, and the second sliding portion 314 and the third sliding portion 330 are connected to the other side of the guide rail 320. In this way, the first sliding portion 313, the second sliding portion 314 and the third sliding portion 330 slide along the guide rail 320 respectively, and then the inner lamp body 1 is driven by the first adjusting member 31 to rotate relative to the outer lamp body 2 fixedly connected to the first adjusting member 32. When the inner lamp body is rotated, the spring piece 33 undergoes elastic deformation to enable smooth sliding; after the inner lamp body completes the rotation, the spring piece 33 is reset and has a damping effect, so that the first adjustment member 31 is limited in the second adjustment member 32, so that the adjusted position is fixed.

[0052] Continue to refer Figure 2-Figure 4 In the first adjusting member 31, the slot 312 is connected to the slide slot 311, the slot 312 is formed downward from the platform 315, and the cross section of the slot 312 has an L-shaped structure. Correspondingly, the spring piece 33 includes a spring piece body 331 and a clamping portion 332, and the clamping portion 332 is formed by bending and extending from both ends of the spring piece body 331. The clamping portion 332 also has an L-shaped structure. After the clamping portion 332 is embedded and installed in the slot 312, the spring piece body 311 with an arc structure is slightly raised in the slide slot 311. The third sliding portion 330 of the spring piece 33 is arranged on the spring piece body 311. After the spring piece 33 is installed to the first adjusting member 31, the third sliding portion 330 and the second sliding portion 314 are located on the same side of the sliding groove 311, and the two are spliced ​​together to form the lower sliding portion of the first adjusting member 31, and the first sliding portion 313 which is an overall arc-shaped structure is the upper sliding portion of the first adjusting member 31.

[0053] Furthermore, the clamping portion 332 is provided with a claw 333 at the end thereof, and the claw 333 abuts against the side wall of the clamping slot 312, so that the spring sheet 33 is tightly connected to the first adjusting member 31. The spring sheet body 331 and the clamping portion 332 of the spring sheet 33 can both be elastically deformed.

[0054] Figure 5 is a schematic diagram of the structure of the second adjusting member of this embodiment, as shown in Figure 5As shown, the second adjusting member 32 includes a base 321 and a slider 322, the slider 322 is formed by protruding from the side of the base 321, and the guide rail 320 is arranged on the slider 322. The base 321, the slider 322 and the guide rail 320 of this embodiment are integrally injection molded. In other embodiments, the base 321, the slider 322 and the guide rail 320 can also be a split structure, and the base 321, the slider 322 and the guide rail 320 are fixed together by bonding or ultrasonic welding.

[0055] The guide rail 320 includes a first guide rail surface 3201 and a second guide rail surface 3202, wherein the first guide rail surface 3201 is located at the upper side of the guide rail 320, and the first guide rail surface 3201 is matched and connected with the first slide portion 313; the second guide rail surface 3202 is located at the lower side of the guide rail, and the second guide rail surface 3202 is matched and connected with the second slide portion 314 and the third slide portion 330. That is, when the first adjustment member 31 slides along the second adjustment member 32, specifically, the first slide portion 313 slides along the first guide rail surface 3201, and the second slide portion 314 and the third slide portion 330 slide along the second guide rail surface 3202.

[0056] The base 321 is provided with a through hole 3211, and the outer lamp body 2 is correspondingly provided with a mounting seat 21. The fastener 4, such as a screw, passes through the through hole 3211 and is fixedly connected to the mounting seat 21, thereby fixing the second adjustment member 321 in the outer lamp body 2.

[0057] It should also be noted that the outer lamp body 2 is also provided with an angle range area 22 and an observation window 23, and the first adjustment member 31 is correspondingly provided with a pointer 316. The direction of the pointer 315 can be observed from the observation window 23, so during the rotation process, the angle to be rotated and adjusted can be clearly determined by the angle value pointed by the pointer 315.

[0058] Figure 6 : is a cross-sectional view of the adjustment component of this embodiment before and after angle adjustment, as shown in FIG. Figure 6 As shown, in the adjustment assembly 3 of 6A, the second adjustment member 32 is fixed in position by the fastener 4; the guide rail 320 of the second adjustment member 32 has a first guide rail surface 3201 located at the top and a second guide rail surface 3202 located at the bottom; and the left end of the guide rail 320 is end A, and the right end is end B.

[0059] The spring piece 33 is installed in the first adjusting member, wherein the third sliding portion 330 of the spring piece 33 is spliced ​​with the second sliding portion 314 to form an arc structure, and forms the lower sliding portion of the first adjusting member 31; the first sliding portion 313 itself is an arc structure, which is the upper sliding portion of the first adjusting member 31. The left end of the slide slot 311 is the C end, and the right end is the D end.

[0060] At this time, the D end of the slide groove 311 abuts against the B end of the guide rail 320, and there is a distance between the C end and the A end; the pointer 316 points to the middle, and the first adjustment member 31 does not rotate relative to the second adjustment member 32. Correspondingly, the light of the lamp body is emitted directly downward.

[0061] In 6B, the first adjusting member 31 rotates relative to the second adjusting member 32, the first sliding portion 313 slides along the first guide surface 3201, and the second sliding portion 314 and the third sliding portion 330 slide along the second guide surface 3202. At this time, the C end of the slide groove 311 gradually approaches the A end of the guide rail 32 and finally abuts against the A end, and the D end gradually moves away from the B end of the guide rail 32, and the pointer 316 deflects. At this time, the rotation angle (swing angle) can reach 35°.

[0062] During the sliding process, the spring piece 33 can undergo elastic deformation to make the sliding smooth; after the sliding is completed, the spring piece 33 resets and abuts against the second guide surface 3202, and the spring piece 33 has a damping effect, so that the first adjustment member 31 is limited in the second adjustment member 32 and the position is fixed, thereby completing the relative position adjustment of the inner lamp body and the outer lamp body, and finally driving the lamp head to rotate relative to the face ring, adjusting the emission angle of the lamp head to meet the lighting needs at different angles.

[0063] Example 2

[0064] Figure 7 FIG. 1 is an exploded view of the lamp of this embodiment. Figure 7 As shown, a lamp, such as a downlight, a spotlight or a ceiling lamp, comprises a lamp holder 200 and a face ring 300, and an angle adjustment mechanism 100 of Embodiment 1, wherein the lamp holder 200 is provided with a light emitting portion 201, the lamp holder 200 is fixedly connected to an inner lamp body 1, and the light emitting portion 201 is arranged inside the inner lamp body 1. The face ring 300 is fixedly connected to an outer lamp body 2, and the face ring is sleeved on the outer side of the outer lamp body 2. The spring piece 33 is embedded and installed in the first adjustment member 31, and then the first adjustment member 31 is embedded and installed in the inner lamp body 1; the fastener 4 fixes the second adjustment member 32 on the outer lamp body 2.

[0065] Figure 8 and Fig. 9 Schematic diagrams of the lamp of this embodiment performing direct lighting and oblique lighting, respectively. Figure 8 As shown, the lamp holder 200 stands upright on the outer lamp body 2 , and through the observation window 23 , it is observed that the pointer 316 points to 0° in the angle range 22 , indicating that the lamp holder 200 does not rotate relative to the outer lamp body 2 and the face ring 300 .

[0066] like Fig. 9As shown, the lamp holder 200 rotates relative to the outer lamp body 2 and the face ring 300. At this time, the bottom end 201 of the outer shell of the lamp holder 200 approaches the clearance position 24 of the outer lamp body 2. Through the observation window 23, it is observed that the pointer 316 points to 35° in the angle range 22, indicating that the lamp holder 200 is deflected to the maximum swing angle, and the bottom end 201 of the outer shell abuts against the clearance position 24.

[0067] The lamp of this embodiment adopts an angle adjustment mechanism having an inner lamp body, an outer lamp body and an adjustment component. On the one hand, the lamp head is driven by the inner lamp body to rotate as needed to adjust the lighting angle; on the other hand, the light output part of the lamp head is located inside the inner lamp body, and the adjustment components are located on both sides of the lamp head, leaving enough space for placing optical components such as reflective cups, thereby increasing the rotation angle range and meeting light control requirements.

[0068] Example 3

[0069] Fig.10 is a flow chart of the angle adjustment method of this embodiment, as shown in Fig.10 As shown, this embodiment provides an angle adjustment method, specifically a lighting angle adjustment method, which uses the angle adjustment mechanism of embodiment 1 or the lamp of embodiment 2. The angle adjustment method specifically includes the following steps:

[0070] 101. Press or push the inner lamp body, and the main body of the shrapnel will be elastically deformed;

[0071] 102. The first sliding part slides along the first guide rail surface of the guide rail; the second sliding part and the third sliding part slide along the second guide rail surface of the guide rail respectively;

[0072] 103. The first adjusting member rotates relative to the second adjusting member;

[0073] 104. The inner lamp head rotates relative to the outer lamp body, and the lamp head rotates relative to the face ring, thereby changing the lighting angle;

[0074] 105. The spring sheet body is elastically reset and abuts against the second guide rail surface.

[0075] In the above angle adjustment method, the third sliding portion of the spring piece is spliced ​​with the second sliding portion to form an arc structure, and forms the lower sliding portion of the first adjustment member; the first sliding portion itself is an arc structure, which is the upper sliding portion of the first adjustment member.

[0076] By pressing or pushing the inner lamp body, the inner lamp head begins to change position relative to the outer lamp body: the first sliding part slides along the first guide surface, the second sliding part and the third sliding part slide along the second guide surface, and the first adjusting part rotates relative to the second adjusting part.

[0077] During the sliding process, the spring body of the spring sheet undergoes elastic deformation, allowing the sliding to proceed smoothly; after the sliding is completed, the spring body is reset to abut against the second guide rail surface, so that the first adjustment member is limited in the second adjustment member and the position is fixed, thereby completing the relative position adjustment of the inner lamp body and the outer lamp body, and ultimately driving the lamp head to rotate relative to the face ring, and then the lighting angle changes to meet the needs of different lighting angles.
