Description

Technical Field

[0001] The present invention relates to the technical field of LED lamps with adjustable lighting angles, and particularly to a lamp angle adjustment structure, a lamp, and an angle adjustment method. Background Art

[0002] Lamps such as spotlights, downlights, ceiling lights, and ceiling-mounted lights are usually installed in the ceiling or suspended ceiling of a building in a direct-down lighting manner when embedded. The light emitted by the light source component of a spotlight is relatively concentrated and is mostly used in occasions of accent lighting; the light emitted by the light source component of a downlight diverges from the panel to the surroundings, the light is relatively dispersed but also relatively uniform, and the lighting range is wider. Consumers can select the above lamps according to the needs of overall lighting, accent lighting, and local daylighting.

[0003] The above-mentioned embedded lamps usually include a lamp body and a face ring arranged on the outer periphery of the lamp body, and the face ring is located in the light emission direction. In some embedded lamps, in order to meet the requirement of adjustable lighting direction, the lamp body can rotate relative to the face ring. However, since the lamp body of the embedded lamp is hidden and installed in the ceiling or suspended ceiling, if the lamp body is rotated by hand, the operation will be difficult, that is, the lighting angle cannot be adjusted as required.

[0004] The prior art discloses a rotatable downlight, including a base and a lamp holder embedded on the base. Two rotating shafts are symmetrically arranged on the side wall of the lamp holder. Fixing plates are arranged on both sides of the base, and the two fixing plates are inclined towards the side away from each other. Rotating holes for the rotating shafts to be embedded are formed on the fixing plates. A plugging hole is formed at one end of the rotating shaft away from the base, and a limiting rod is detachably connected in the plugging hole. A limiting component for abutting against the rod body of the limiting rod is arranged on the fixing plate. After the rotating shaft is embedded into the rotating hole and the limiting rod is installed into the plugging hole, the lamp holder is rotated to adjust its irradiation direction. However, for this downlight, it is necessary to screw the abutting bolt so that one end of the abutting block abuts against the limiting rod, thereby rotating and fixing the rotation angle of the lamp holder, that is, the downlight still needs to be removed from the installation hole for adjustment.

[0005] Therefore, it is necessary to optimize the existing lamp rotation structure to provide an adjustment structure that can easily rotate the lamp head and the corresponding lamp. Summary of the Invention

[0051] Embodiment 1

[0052] As Figure 1As shown in the exploded view of the lamp angle adjustment structure, a lamp angle adjustment structure 100 includes a first lamp body 1, a second lamp body 2, a lamp head 3, and an adjustment assembly 4. Among them, the lamp head 3 is the light-emitting main body of the lamp, and the lamp body 3 has a housing 31, and an installation cavity is formed inside the housing 31. It can be understood that a light source module, an optical module, a power module, and a heat dissipation module are arranged in the installation cavity. The power module supplies power to the light source module. After the light emitted by the light source module is processed by the optical module, it is then emitted through the first lamp body 1 and the second lamp body 2. The heat dissipation module conducts the heat generated by the light source module and the power module to the outside.

[0053] The first lamp body 1 is arranged at the front end in the light-emitting direction of the lamp head 3. Among them, the first lamp body 1 is fixedly connected to the lamp head 3, and the second lamp body 2 is arranged on the outer periphery of the first lamp body 1. In this embodiment, the second lamp body 2 is a lamp body frame member with a fixed position. The first lamp body 1 is rotatably connected to the second lamp body 2 through the adjustment assembly 4. Specifically, the first lamp body 1 can rotate relative to the second lamp body 2, and the lamp head 3 also rotates with the first lamp body 1, thereby adjusting the light-emitting direction.

[0054] Figure 2 The structure of the first lamp body and the adjustment assembly in this embodiment is shown in Figure 2 As shown, the first lamp body 1 arranged at the front end in the light-emitting direction of the lamp head 3 has a light guiding function and also has a light shielding function. The first lamp body 1 includes a first side wall 11 and a second side wall 12 arranged in parallel, and a first arc block 13 and a second arc block 14 located between the first side wall 11 and the second side wall 12. A slot 111 is provided on the first side wall 11 for connecting with the adjustment assembly 4.

[0055] The adjustment assembly 4 in this embodiment includes a rotating member 41, an adjustment ball 42, and an adjustment member 43. The rotating member 41 is embedded and connected in the slot 111 of the first lamp body 1, and the rotating member is provided with a first chute 411, a second chute 412, and a clamping groove 413. The adjustment ball is a metal ball provided with an adjustment hole 421, and the adjustment ball 42 is arranged in the clamping groove 413. Since the adjustment hole 421 is a cylindrical hole penetrating the entire sphere, the first chute 411 and the second chute 412 are respectively communicated with the adjustment hole 421.

[0056] The adjusting member 43 is a columnar metal member provided with a threaded post 431 and an adjusting end portion 432. Corresponding to the threaded post 431, the adjusting hole 421 is also provided with threads on the inner sidewall. The adjusting member 43 is connected to the second lamp body 2. Moreover, after the adjusting member 43 passes through the second chute 412, the adjusting hole 421, and the first chute 411, the stud 431 can travel in the adjusting hole 421 with threads provided on the inner sidewall. By horizontally rotating the adjusting end portion 432 of the adjusting member 43, the adjusting member 43 can move up or down relative to the rotating member 41 and the adjusting ball 42. At this time, the rotating member 41 rotates, thereby driving the first lamp body 1 to rotate relative to the second lamp body 2, so that the light-emitting angle of the lamp head 3 also changes, and thus the light-emitting angle can be adjusted as needed.

[0057] Figure 3 is a schematic structural diagram of the rotating member, as Figure 3 shown, the rotating member 41 includes a first substrate 4101 and a second substrate 4102, and the second substrate 4102 is perpendicular to the first substrate 4101. The first substrate 4101 and the second substrate 4102 of this embodiment are integrally formed, and the first substrate 4101 and the second substrate 4102 can be prepared by stamping and cutting. In some embodiments, the first substrate 4101 and the second substrate 4102 can also be a split structure and are fixed together by welding or bonding. It can be understood that in the rotating member 41 of this embodiment, the first substrate 4101 and the second substrate 4102 form an L-shaped plate structure. The second substrate 4102 is provided with a first convex block 4103 and a second convex block 4104 protruding toward the slot direction at the edge portion, and the second convex block 4104 is parallel to the first convex block 4103. The first chute 411 is opened on the first convex block 4103, and the second chute 412 is opened on the second convex block 4104.

[0058] Combined with reference to Figures 1-3 , when the rotating member 41 is embedded and installed into the first lamp body 1, the first substrate 4101 and the second substrate 4102 are located between the first lamp body 1 and the second lamp body 2, and the first convex block 4103 and the second convex block 4104 are inserted and connected to the slot 111.

[0059] In some embodiments, the first chute 411 and the second chute 412 have an elliptical slot structure; in other embodiments, the first chute 411 and the second chute 412 have a racetrack-shaped slot structure. The slots of the first chute 411 and the second chute 412 in this embodiment are of an elliptical structure, and the length of the first chute 411 is greater than the length of the second chute 412.

[0060] The clamping groove 413 is located between the first convex block 4103 and the second convex block 4104, and the clamping groove 413 communicates with the first chute 411 and the second chute 412. The adjusting ball 42 installed in the clamping groove 413 forms a first opening 4 on the spherical surface

[0061] Figure 4 This is a schematic structural diagram of the adjustment ball of this embodiment. As Figure 4 shown, the structural diagrams 4A and 4B of the adjustment ball are given from two perspectives. The adjustment hole 421 is a columnar hole that penetrates the entire adjustment ball 4, that is, the central axis of the adjustment hole 421 passes through the center of the adjustment ball 4. Threads are provided on the inner side wall of the adjustment hole 421, so as to be screwed and connected with the threaded column 431 of the adjustment member 43. With reference to 4A and 4B, the adjustment hole 421 forms a first opening 422 and a second opening 423 on the surface of the adjustment ball 42. A first ring body 4201 is formed on the outer periphery of the first opening 422, and a second ring body 4202 is formed on the outer periphery of the second opening 423.

[0062] Figure 5 This is a cross-sectional view of the adjustment assembly of this embodiment. With reference to Figures 2-5 it, the first ring body 4201 of the adjustment ball 42 is in fit connection with the first convex block 4103, and a first fit site 441 is formed; the second ring body 4202 is in fit connection with the second convex block 4104, and a second fit site 442 is formed. When the adjustment member 43 rotates up or down, the first fit site 441 moves along the first chute 411, and the second fit site 442 moves along the second chute 412.

[0063] Figure 6 This is a schematic structural diagram of the second lamp body of this embodiment. With reference to Figure 1 and Figure 6 it, the second lamp body 2 is provided with a base 21 facing the inner cavity. An installation hole 22 is opened on the base 21. After passing through the installation hole 22, the adjustment member 43 is connected to the rotating member 41 and the adjustment ball 42.

[0064] As Figures 1-6 shown, the first lamp body 1 is provided with a first through hole 112, and the second lamp body 2 is provided with a second through hole 23. The rotating member 41 is provided with a third through hole 414 on the first substrate 4101. The pivot member 24 passes through the second through hole 23, the third through hole 414, and the first through hole 112 to connect the second lamp body 2, the rotating member 41, and the first lamp body 1 together. Since the position of the second lamp body 2 is fixed, in this way, when the rotating member 41 rotates, the first lamp body 1 is also driven to rotate.

[0065] Figure 7 This is a schematic structural diagram of the downlight illumination of this embodiment. As Figure 7As shown, the front end of the lamp head 3 is inserted and installed in the first lamp body 1 and irradiates vertically downward, that is, the first lamp body 1 and the lamp head 3 do not rotate relative to the second lamp body 2, that is, the illumination angle does not change. At this time, in the adjusting assembly 4, the threaded column 431 of the adjusting member 43 passes through the rotating member 431 and the adjusting ball 42, and there is a relatively long threaded rotation distance between the adjusting end 432 and the second convex block 4104 of the rotating member 41.

[0066] Figure 8 This is a schematic structural diagram of the obliquely downward illumination of the lamp head in this embodiment. As Figure 8 shown, the first lamp body 1 and the lamp head 3 rotate relative to the second lamp body 2, that is, the illumination angle changes. Specifically, in the adjusting assembly 4, a tool such as a screwdriver is used to rotate the adjusting end 432 of the adjusting member 43 to make the adjusting end 432 move upward. The threaded column 431 travels in the adjusting hole of the adjusting ball 42, and the distance between the adjusting end 432 and the second convex block 4104 of the rotating member 41 shortens, and the first fitting site also moves from one end of the first sliding groove to the other end. The rotating member 41 rotates with the pivot member 24 as the rotation axis, thereby driving the first lamp body 1 and the lamp head 3 to rotate relative to the second lamp body 2, and further adjusting the illumination angle.

[0067] In the lamp angle adjusting structure of this embodiment, the position of the second lamp body is fixed and arranged on the outer periphery of the first lamp body. The first lamp body fixedly connected to the lamp body is rotationally connected to the second lamp body through the adjusting assembly; when using an (inner hexagon) screwdriver to rotate the adjusting member of the adjusting assembly, the adjusting member can rise or fall, and then the rotating member of the adjusting assembly rotates accordingly, and finally drives the first lamp body and the lamp head to rotate relative to the second lamp body, so as to adjust the emission angle of the lamp head to meet the illumination requirements of different angles.

[0068] Embodiment 2

[0069] Figure 9 This is a schematic diagram of the angle adjustment by the adjusting assembly in this embodiment. As Figure 9 shown, the central axis of the adjusting member 43 is x, and the normal lines of the first convex block 4103 and the second convex block 4104 of the rotating member 41 are y.

[0070] In 9A, the rotating member 41 does not rotate. At this time, the first lamp body connected to the rotating member 41 also does not rotate, and the lamp head emits light straight down; the normal line y is parallel to the central axis x, and there is a relatively long threaded column distance between the adjusting end 432 and the second convex block 4104; both the first fitting site 441 and the second fitting site 442 are close to the N end.

[0071] In 9B, after rotating the adjusting end 432, as the adjusting end 432 moves upward, the threaded post distance between the adjusting end 432 and the second bump 4104 gradually shortens. Both the first fitting site 441 and the second fitting site 442 start to move from the N end to the M end, and the normal line y forms an angle θ with the central axis x. At this time, θ = 15°.

[0072] In 9C, after continuing to rotate the adjusting end 432, the adjusting end 432 continues to move upward, the threaded post distance between the adjusting end 432 and the second bump 4104 continues to shorten, and the first fitting site 441 and the second fitting site 442 also continue to move from the N end to the M end. Moreover, the travel distance of the second fitting site 442 is greater than that of the first fitting site 441. At this time, the angle θ between the normal line y and the central axis x is 40°.

[0073] When the lamp head adjusts the angle downward, the first fitting site 441 where the adjusting ball contacts the first bump is stressed, causing the rotating member 41 to swing, thereby driving the first lamp body and the lamp head to rotate.

[0074] When the lamp head adjusts the angle upward, the second fitting site 442 where the adjusting ball contacts the second bump is stressed, causing the rotating member 41 to swing, thereby driving the first lamp body and the lamp head to rotate.

[0075] Embodiment 3

[0076] Figure 10 It is a schematic diagram of the lamp angle adjustment of this embodiment. As Figure 10 shown, a lamp includes a face ring 200 and the above-mentioned lamp angle adjustment structure 100. Among them, the face ring 200 is snap-connected to the outer periphery of the second lamp body 2. An angle adjustment value, such as "0, 5, 10, 15, 20, 25, 30, 35, 40", with the unit of "°", is set on the housing 31 of the lamp head 3, which is convenient for users to adjust the illumination angle as needed.

[0077] When the angle of the lamp of this embodiment needs to be adjusted, as shown in Figure 10A, a hexagon screwdriver can be used to horizontally rotate the adjusting end of the adjusting member. As the adjusting end moves upward, the threaded post distance between the adjusting end and the second bump shortens. As shown in Figure 10B, the rotating member rotates, thereby driving the first lamp body to rotate and finally driving the rotation of the lamp head. The amplitude of the screwdriver rotating the adjusting end corresponds to the rotation angle, and the lamp head can be adjusted to the required illumination angle.

[0078] Embodiment 4

[0079] Figure 11 It is a flowchart of the angle adjustment method of Embodiment 4. As Figure 11As shown, this embodiment provides an angle adjustment method, specifically a lighting angle adjustment method, which uses the lamp angle adjustment structure of Embodiment 1 and Embodiment 2, or the lamp of Embodiment 3. This lighting angle adjustment method specifically includes:

[0080] 101. Horizontal rotation adjustment member;

[0081] 102. The adjustment member rises or falls relative to the rotating member;

[0082] 103. The first fitting site moves along the first sliding groove, and the second fitting site moves along the second sliding groove;

[0083] 104. The rotating member rotates and drives the first lamp body to rotate relative to the second lamp body;

[0084] 105. The lamp head rotates and the lighting angle changes.

[0085] The horizontal rotation adjustment member can use an external tool, such as an Allen key screwdriver, to horizontally rotate the adjustment end of the adjustment member; in some embodiments, the adjustment member can also be rotated by hand.

[0086] After horizontally rotating the adjustment member, the adjustment member rises or falls relative to the rotating member. Specifically, the distance between the adjustment end of the adjustment member and the second convex block changes.

[0087] During the adjustment process, the first fitting site moves along the first sliding groove, and the second fitting site moves along the second sliding groove:

[0088] When the lamp head adjusts the angle downward, the first fitting site is stressed, causing the rotating member to swing;

[0089] When the lamp head adjusts the angle upward, the second fitting site is stressed, causing the rotating member to swing;

[0090] After the rotating member rotates, it drives the first lamp body to rotate relative to the second lamp body;

[0091] Finally, the lamp head rotates and the lighting angle changes.

[0092] The angle adjustment method provided in this embodiment uses tools such as a screwdriver to horizontally rotate the adjustment member, and can adjust the swing angle of the lamp head as needed, so as to accurately adjust the lighting angle.

[0093] The above content is only an example and description of the structure of the present invention. Its description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made, and these obvious replacement forms all belong to the protection scope of the present invention.
