Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lighting fixture with an adjustable light output angle. Background Technology

[0002] Lighting fixtures are essential tools in daily life. As people's aesthetic standards improve, different indoor environments and usage scenarios lead to different demands for the light emission angle of lighting fixtures. Existing lighting fixtures typically use lampshades to set the light emission angle of the light source. However, the structure of the lampshade is relatively bulky and not suitable for use with thinner lighting fixtures. Changing the light emission angle also requires changing the lampshade, which is inconvenient. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides a lamp with an adjustable light angle.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A lamp with adjustable beam angle, comprising:

[0005] A support plate, wherein a guide is provided on the upper side of the support plate, the guide has a guide slope with varying height, and a clearance opening is provided on the support plate that extends vertically, the clearance opening being positioned corresponding to the guide slope.

[0006] A lens disk has an upwardly extending upper plate and a laterally extending locking pin. The lens disk is located below a support disk and passes through a clearance opening via the upper plate, placing the locking pin on a guide slope. The height of the locking pin on the guide slope is adjusted by changing the relative position of the lens disk and the support disk, thereby adjusting the distance between the lens disk and the support disk.

[0007] The lamp panel is installed below the support plate and between the support plate and the lens plate. The light emission angle can be adjusted by changing the distance between the lamp panel and the lens plate.

[0008] Furthermore, the support disk has a central axis, and a number of guide members are arranged as a group. The guide members in the group are arranged in a rotating array along the central axis. The guide members have an arc-shaped structure with the central axis as the center. The clearance opening extends arc-shapedly along the guide slope and is formed by opening downward from the middle of the guide slope. A number of upper extension plates are arranged as a group on the lens disk. The upper extension plates in the group are arranged in a rotating array along the central axis. One upper extension plate corresponds to one guide member. The retaining shaft extends laterally from the upper extension plate to both sides and is placed on the guide slope respectively. The lens disk rotates around the central axis.

[0009] Furthermore, the support disk and lens disk have a circular structure, and a number of guide members and corresponding upper extension plates respectively form an inner ring group and an outer ring group. The inner ring group is located near the central axis, and the outer ring group is located at the outer edge.

[0010] Furthermore, the retaining shaft is formed by a pin that passes through and is mounted on the upper extension plate.

[0011] Furthermore, the support plate is also provided with a cover, which is installed above the guide member. The cover has an upper guide surface, which is used to limit the top of the upper extension plate. The upper guide surface has a height variation shape that is adapted to the guide slope, so that the distance from each position of the guide slope to the upper guide surface is consistent.

[0012] Furthermore, the guide slope includes several horizontal sections and several inclined sections, with the horizontal sections arranged in a descending order of height, and the inclined sections located between two adjacent horizontal sections.

[0013] Furthermore, a spring sheet structure is formed on the upper guide surface above the horizontal section. The spring sheet structure is provided with a downward protruding positioning protrusion. The top of the upper extension plate is provided with a downward recessed positioning groove. When the upper extension plate is in the position corresponding to the horizontal section, the positioning protrusion is embedded in the positioning groove to limit the position of the upper extension plate. When the spring sheet structure is subjected to external force, deformation can cause the positioning protrusion to disengage or be placed into the positioning groove.

[0014] Furthermore, the support plate is provided with a first mark, and the lens plate is provided with a second mark. The first mark and the second mark are positioned close to each other, and the positional correspondence between the first mark and the second mark is used to indicate the positional status of the lens plate.

[0015] Furthermore, the inner and outer sides of the lens disk are respectively provided with a ring-shaped vertical edge, and the bottom of the support disk is respectively provided with a ring-shaped closure at the inner and outer positions. The two sets of closures are adapted to the two vertical edges to form an inner waterproof structure and an outer waterproof structure, respectively. The lamp panel has a ring structure and is located between the inner waterproof structure and the outer waterproof structure.

[0016] Furthermore, the closure includes a silicone ring and a fixing ring. The fixing ring fixes the silicone ring to the support plate. The silicone ring has several protruding rings extending towards the vertical edge. The protruding rings are pressed against the vertical edge, and the protruding rings are arranged vertically at intervals.

[0017] As can be seen from the above description of this utility model, compared with the prior art, the adjustable light emission angle lamp provided by this utility model has the following advantages: This application achieves the change of light emission angle by adjusting the distance between the lens disk and the lamp panel, requiring only a small adjustment in height to achieve the change of light emission angle, and can be adapted to planar lamps. The adjustment structure of this application adopts a structure in which the locking shaft moves along the guide slope, and several horizontal parts are set on the guide slope to correspond to multiple different light emission angles. The design of the positioning groove and the positioning protrusion on the spring structure provides damping and precise positioning when the lens disk rotates into the set position, enabling precise setting of the light emission angle. The inner ring group and outer ring group design of this application provide a reliable support structure and a reliable rotation and positioning structure between the support plate and the lens disk. The lamp panel is located between the inner waterproof structure and the outer waterproof structure, and the lamp panel is not affected by external splashes of water, achieving an IP65 waterproof rating.

[0029] The present invention will be further described below through specific embodiments.

[0030] Reference Figures 1 to 10 As shown, a lamp with adjustable light angle includes a support plate 1, a lens plate 2, and a lamp panel 3.

[0031] A guide member 11 is provided on the upper side of the support plate 1. The guide member 11 has a guide slope 12 with varying height. A clearance opening 13 is provided on the support plate 1, which is positioned corresponding to the guide slope 12. An upper extension plate 21 is provided on the lens plate 2, which has a horizontally extending retaining shaft 22. The lens plate 2 is located below the support plate 1 and passes through the clearance opening 13 via the upper extension plate 21, so that the retaining shaft 22 is placed on the guide slope 12. The height position of the retaining shaft 22 on the guide slope 12 is adjusted by changing the relative position of the lens plate 2 and the support plate 1, thereby adjusting the distance between the lens plate 2 and the support plate 1. A lamp plate 3 is installed below the support plate 1 and between the support plate 1 and the lens plate 2. The light emission angle can be adjusted by changing the distance between the lamp plate 3 and the lens plate 2.

[0032] The support disk 1 has a central axis and is provided with a group of several guide members 11. The guide members 11 in the group are arranged in a rotating array along the central axis. The guide members 11 have an arc-shaped structure with the central axis as the center. The clearance opening 13 extends arc-shapedly along the guide slope 12 and is formed by opening downward from the middle of the guide slope 12. The lens disk 2 is provided with a group of several upper extension plates 21. The upper extension plates 21 in the group are arranged in a rotating array along the central axis. Each upper extension plate 21 corresponds to one guide member 11. The retaining shaft 22 extends laterally from the upper extension plate 21 to both sides and is placed on the guide slope 111 respectively. In a preferred embodiment, the retaining shaft 22 is formed by a pin that passes through and is installed in the upper extension plate 21. The lens disk 2 rotates around the central axis. The support disk 1 and the lens disk 2 have a circular structure. The several guide members 11 and the corresponding several upper extension plates 21 respectively form an inner ring group a and an outer ring group b. The inner ring group a is located near the central axis, and the outer ring group b is located at the outer edge. The inner ring group a and outer ring group b in this application are designed to provide a reliable support structure and a reliable rotation and positioning structure between the support disk 1 and the lens disk 2.

[0033] The support plate 1 is also provided with a cover 4, which is installed above the guide member 11. The cover 4 has an upper guide surface 41, which is used to limit the top of the upper extension plate 21. The upper guide surface 41 has a height variation shape that is adapted to the guide slope 12, so that the distance from each position of the guide slope 12 to the upper guide surface 41 is consistent. The guide slope 12 includes several horizontal sections 121 and several inclined sections 122. The horizontal sections 121 are arranged in a descending order of height. The inclined sections 122 are located between two adjacent horizontal sections 121. A spring sheet structure 42 is formed on the upper guide surface 41 above the horizontal section 121. The spring sheet structure 42 has a downwardly protruding positioning protrusion 421. The top of the upper extension plate 21 has a downwardly recessed positioning groove 211. When the upper extension plate 21 is in the position corresponding to the horizontal section 121, the positioning protrusion 421 is embedded in the positioning groove 211, thus limiting the position of the upper extension plate 21. When the spring sheet structure 42 is subjected to external force, deformation can cause the positioning protrusion 421 to disengage or enter the positioning groove 211. The design of the spring sheet structure 42 and its mating parts realizes the damping sensation when the lens disk 2 rotates into the set position, enabling precise angle positioning.

[0034] The support plate 1 is provided with a first mark 14, and the lens plate 2 is provided with a second mark 23. The first mark 14 and the second mark 23 are positioned close to each other, and their corresponding positions are used to indicate the position of the lens plate 2. Specifically, the first mark 14 is an arrow, and the second mark 23 is a number of light emission angle marks. Each light emission angle mark corresponds to a horizontal part 121 and indicates the light emission angle.

[0035] The lens disk 2 has an annular vertical edge 24 on its inner and outer sides, and the support disk 1 has an annular closure 15 on its inner and outer sides at its bottom. The two closures 15 are adapted to the two vertical edges 24 to form an inner waterproof structure c and an outer waterproof structure d, respectively. The lamp plate 3 has a circular structure and is located between the inner waterproof structure c and the outer waterproof structure d. The closure 15 includes a silicone ring 151 and a fixing ring 152. The fixing ring 152 fixes the silicone ring 151 to the support disk 1. The silicone ring 151 has several protruding rings 1511 extending towards the vertical edge 24. The protruding rings 1511 and the vertical edge 24 are pressed against each other, and the protruding rings 1511 are arranged vertically at intervals. The several protruding rings ensure that the waterproof structure maintains reliable waterproof performance during the rotation and lifting of the lens disk. The lamp disk of this application is located between the inner waterproof structure c and the outer waterproof structure d, ensuring that the lamp disk, which is an electrical component, is not affected by external splashes of water, and can achieve IP65 waterproof rating.

[0036] The working principle of this application is as follows:

[0037] The lens disk 2 has an optical lens structure. Light emitted from the LEDs on the lamp panel 3 passes through the lens disk 2 and is emitted after refraction by the lens disk 2, forming an emission angle. Changing the distance between the lens disk 2 and the lamp panel 3 will change the angle of light refraction, thereby changing the emission angle of the lamp. The lamp panel 3 is fixedly installed below the support plate 1, and the lens disk 2 is adjustablely installed below the support plate 1. Therefore, the emission angle can be adjusted by adjusting the positional relationship between the lens disk 2 and the support plate 1. The specific adjustment method is as follows: An external force pushes the lens disk 2 to rotate around the central axis, and the retaining shaft 22 moves along the guide slope 12, that is, from one horizontal section 121 through the inclined section 122 to another horizontal section 121. When the retaining shaft 22 reaches one horizontal section 121, the upper extension plate 21 also reaches the position of a positioning protrusion 421. A certain external force is applied to deform the spring structure 42, so that the positioning protrusion 421 moves up and down and is embedded in the positioning groove 211. At this time, the upper extension plate 21 is in a positioning state, and the lens disk 2 is correspondingly positioned at a certain height, forming a set light emission angle. The light emission angle can be achieved by adjusting the specific lens size and optical parameters, which will not be elaborated here. When it is necessary to change the light emission angle again, the lens disk 2 can be rotated in the same way as described above. The multiple horizontal sections 121 provided in the guide member 11 correspond to multiple set light emission angles. That is, this application has the function of adjusting multiple light emission angles.

[0038] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be considered as an infringement of the protection scope of the present utility model.
