Description

Technical Field

[0001] This utility model patent relates to the technical field of polarization adjustable lamps, specifically to angle adjustable lamps. Background Technology

[0002] Lenses are optical systems used to change the light field distribution of LEDs. They are generally composed of through-lenses and / or reflective lenses. When the light from an LED passes through a through-lens, it is refracted and focused. When the light from an LED passes through a reflective lens, it is reflected and focused, thereby enhancing the light utilization efficiency and luminous efficiency.

[0003] Currently, in certain special occasions, such as museums and exhibition halls, the size of the objects to be illuminated varies, so the lamps need to have multiple beam angles in order to achieve a better lighting or supplementary lighting effect.

[0004] For example, the prior patent with authorization announcement number CN208204894U discloses a lamp with an adjustable light spot, including a lamp body, which includes a light source, optical elements and a fixing cylinder. The fixing cylinder is positioned facing the light source. The optical elements include a lens, a first polarizing plate and a second polarizing plate. Both the first polarizing plate and the second polarizing plate adopt a microlens array structure. A limiting part is provided at the end of the fixing cylinder away from the light source. The lens is placed inside the fixing cylinder and limited by the limiting part. Two pairs of buckles of different heights are also provided on the outside of the limiting part. The first polarizing plate and the second polarizing plate can be rotatably embedded in these two pairs of buckles. The lens, the first polarizing plate and the second polarizing plate are arranged in sequence in front of the light source.

[0005] In the existing technology, the lamps require a large number of parts to achieve angle adjustment, which makes the lamp angle adjustment complex and unstable. At the same time, it results in a large size of lamps, increases the assembly space of lamps, and makes lamp assembly inconvenient. Utility Model Content

[0006] The purpose of this invention is to provide an angle-adjustable lamp, which aims to solve the problem of inconvenient angle adjustment in existing lamps.

[0007] This utility model is implemented as follows: an angle-adjustable lamp includes a lens body, an adjusting ring, a connecting shell, a lamp housing, and a light source. The light source is assembled with the lamp housing and emits light toward the lens body. The connecting shell covers the lens body and is used to assemble the lens body with the adjusting ring. The adjusting ring is movably assembled with the lamp housing. The connecting shell or the adjusting ring is driven to swing relative to the lamp housing, and the lens body is driven to swing relative to the lamp housing.

[0008] Furthermore, the connecting shell has a connecting head that is protruding outwards and is arranged correspondingly to the total reflection surface of the lens body. The adjusting ring has an adjusting groove, and the connecting head is embedded in the adjusting groove.

[0009] Furthermore, the connecting shell has three connecting heads, which are arranged in a circumferentially spaced manner, and the adjusting ring has three adjusting grooves, which are arranged in a one-to-one correspondence with the three adjusting grooves and are all embedded in each other.

[0010] Furthermore, the adjustment ring includes a main adjustment ring and a light guide ring, which are integrally formed and arranged to form a mirror stage, which is used to abut the lens body; the main adjustment ring forms the adjustment groove.

[0011] Furthermore, the light guide ring is arranged facing the lens body, and the diameter of the light guide ring gradually increases along the direction away from the lens body.

[0012] Furthermore, the connecting shell includes multiple connecting pieces and multiple fixing pieces, with each connecting piece and each fixing piece arranged sequentially and at intervals around the lens body. The fixing pieces are fastened to the lens body, and the ends of the connecting pieces protrude in a direction away from the lens body to form the connecting head.

[0013] Furthermore, the lens body has a light-emitting ring, which forms a light-emitting surface for projecting light to form a light spot; the light-emitting ring has at least one annular groove, and the annular groove is provided with an annular block, which is arranged in a convex manner; the fixing piece includes a main fixing piece and an extension fixing piece, which are integrally formed; the main fixing piece is stacked with the lens body, and the main fixing piece is in contact with the light-emitting ring; the extension fixing piece is embedded in the annular groove, and the annular block is embedded with the extension fixing piece.

[0014] Furthermore, the lamp housing includes a front ring and a fixed ring, which are threadedly connected; the front ring has a front ring surface and the fixed ring has a fixed surface, which are respectively curved and simultaneously abut against the outer surface of the adjusting ring.

[0015] Furthermore, the front ring has a guide ring surface, which is arranged to be aligned with the front ring surface.

[0017] Compared with the prior art, the angle-adjustable lamp provided by this utility model emits light to the lens body during use, and the light is projected outward by the lens body to form a light spot. When the lamp needs to be adjusted, the connecting shell or adjusting ring is driven to swing relative to the lamp housing, which in turn causes the lens body to swing relative to the lamp housing, thereby realizing the angle adjustment of the light. Under the action of the connecting shell, the lens body and the adjusting ring are assembled. At the same time, the rotation radius of the adjusting ring is reduced, thereby reducing the internal radius of the lamp and thus reducing the size of the lamp, which facilitates the assembly of the lamp.

[0025] Reference Figure 1-4 The image shown is a preferred embodiment of the present invention.

[0026] An angle-adjustable luminaire includes a lens body 1, an adjusting ring 2, a connecting shell 3, a lamp housing 4, and a light source 5. The light source 5 and the lamp housing 4 are assembled together. The light source 5 is used to emit light toward the lens body 1. The connecting shell 3 covers the lens body 1 and is used to assemble the lens body 1 with the adjusting ring 2. The adjusting ring 2 and the lamp housing 4 are movably assembled together. The connecting shell 3 or the adjusting ring 2 is driven to swing relative to the lamp housing 4, and the lens body 1 is driven to swing relative to the lamp housing 4.

[0027] In the aforementioned angle-adjustable luminaire, when in use, the light source 5 emits light to the lens body 1, which projects light outward to form a light spot. When the luminaire needs adjustment, the connecting shell 3 or the adjusting ring 2 is driven to swing relative to the lamp housing 4, causing the lens body 1 to swing relative to the lamp housing 4, thereby adjusting the angle of the light. Under the action of the connecting shell 3, the lens body 1 and the adjusting ring 2 are assembled. At the same time, the rotation radius of the adjusting ring 2 is reduced, thereby reducing the internal radius of the luminaire and thus reducing the size of the luminaire, making the assembly of the luminaire easier.

[0028] The connecting shell 3 or the adjusting ring 2 is driven to swing relative to the lamp housing 4, and the rotation range of the connecting shell 3 or the adjusting ring 2 is 0-360 degrees; thus, the lens body 1 has a 360-degree angle adjustment range.

[0029] The connecting shell 3 has a connector 31, which is arranged to protrude outwards. The connector 31 is arranged in a corresponding manner to the total reflection surface of the lens body 1. The adjusting ring 2 has an adjusting groove 21, and the connector 31 is embedded in the adjusting groove 21.

[0030] By embedding the connector 31 and the adjustment groove 21, the connecting shell 3 and the adjustment ring 2 are assembled, thereby realizing the assembly of the lens body 1 and the adjustment ring 2; with the cooperation of the connector 31 and the adjustment groove 21, the assembly stability of the connecting shell 3 and the adjustment ring 2 is enhanced.

[0031] The connecting shell 3 has three connectors 31, which are arranged in a circumferentially spaced manner. The adjusting ring 2 has three adjusting grooves 21. The three connectors 31 and the three adjusting grooves 21 are arranged in a one-to-one correspondence and are all embedded in each other. In this way, through the cooperation of the three connectors 31 and the three adjusting grooves 21, the assembly force of the connecting shell 3 and the adjusting ring 2 is more uniform, and the multi-area reinforcement enhances the assembly stability of the connecting shell 3 and the adjusting ring 2.

[0032] The adjustment ring 2 includes a main adjustment ring and a light guide ring. The main adjustment ring and the light guide ring are integrally formed and form a mirror stage. The mirror stage is used to contact the lens body 1. Under the action of the mirror stage, the lens body 1 is positioned and reinforced, thereby enhancing the stability of the lens body 1.

[0033] The main adjustment ring forms an adjustment groove 21. This design of the adjustment groove 21 reduces the rotation radius of the adjustment ring 2, eliminating the need for a large space to accommodate the rotation of the adjustment ring 2, thereby reducing the overall size of the lamp.

[0034] The light guide ring is arranged facing the lens body 1, and the diameter of the light guide ring gradually increases along the direction away from the lens body 1. In this way, the light guide ring facilitates the projection of light and the formation of light spots. At the same time, the light guide ring plays a role in cutting off light, preventing light leakage, and improving the presentation effect of the light spots.

[0035] Example 1 of connecting shell 3: The connecting shell 3 includes a connecting cover 34 and a plurality of connecting pieces 32. The inner end of the connecting piece 32 is arranged in a mating arrangement with the connecting cover 34. The other end of the connecting piece 32 is raised in a direction away from the connecting cover 34 and forms a connecting head 31. Each connecting piece 32 is arranged in a spaced-around arrangement around the connecting cover 34. Under the action of the connecting cover 34, the assembly stability with the lens body 1 is achieved.

[0036] Example 2 of connecting shell 3: The connecting shell 3 includes multiple connecting pieces 32 and multiple fixing pieces 33. The connecting pieces 32 and the fixing pieces 33 are arranged in a sequential and spaced manner around each other. The fixing pieces 33 are fastened to the lens body 1. The ends of the connecting pieces 32 protrude in a direction away from the lens body 1 and form a connector 31. Under the action of the fixing pieces 33, the assembly of the connecting shell 3 and the lens body 1 is realized.

[0037] The lens body 1 has a light-emitting ring 11, which forms a light-emitting surface for projecting light to form a light spot. The light-emitting ring 11 has at least one ring groove, and the ring groove is provided with a ring block. The ring block is arranged in a convex manner. The fixing piece 33 includes a main fixing piece and an extension fixing piece. The main fixing piece and the extension fixing piece are integrally formed. The main fixing piece is stacked with the lens body 1, and the main fixing piece is in contact with the light-emitting ring 11. The extension fixing piece is embedded in the ring groove, and the ring block is embedded with the extension fixing piece.

[0038] The combination of the ring block and the extension plate enhances the assembly stability of the connecting shell 3 and the lens body 1.

[0039] Furthermore, the main fixing plate has a main fixing groove, and the extension fixing plate has an extension fixing groove. The main fixing groove and the extension fixing groove are arranged in a connected manner, and the main fixing groove and the extension fixing groove are arranged in a through manner. The annular block is embedded with the extension fixing groove. With the cooperation of the main fixing groove and the extension fixing groove, it is convenient for the annular block to be embedded with the extension fixing groove, thereby facilitating the assembly of the connecting shell 3 and the lens body 1.

[0040] The lamp housing 4 includes a front ring and a fixed ring, which are arranged in a threaded connection; this facilitates assembly and disassembly, and also facilitates the assembly and disassembly of the adjusting ring 2 and the lens body 1.

[0041] The front ring has a front ring surface, and the fixed ring has a fixed surface. The front ring surface and the fixed surface are respectively arranged in a curved shape. The front ring surface and the fixed surface are arranged to abut against the outer surface of the adjusting ring 2. Under the action of the front ring surface and the fixed surface, the rotation of the adjusting ring 2 is guided and positioned, thereby improving the smoothness and stability of the angle adjustment of the adjusting ring 2.

[0042] The front ring component has a guide ring surface, which is arranged to be aligned with the front ring surface. The diameter of the guide ring surface gradually increases in the direction away from the front ring surface. The outer surface of the adjusting ring 2 is arranged to correspond with the guide ring surface. In this way, the guide ring surface provides more space for the angle adjustment of the adjusting ring 2, avoids obstruction of the angle adjustment of the adjusting ring 2, and thus ensures the angle adjustment of the adjusting ring 2.

[0043] Angle-adjustable luminaires include a power component that applies driving force. The power component is assembled with the connecting housing 3 or the adjusting ring 2 to achieve automatic adjustment of the luminaire's beam angle.

[0044] Alternatively, the power component, connecting housing 3, and adjusting ring 2 can be assembled synchronously to achieve automated adjustment of the lamp's beam angle.

[0045] When the lens body 1 is adjusted and swings, the light spot formed by the lens body 1 gradually changes in the direction of increasing smooth angle; the light spot that is not adjusted is still complete and smooth.

[0046] The power component can be an electric motor or a cylinder.

[0047] The principle of reducing the radius of rotation:

[0048] As attached Figure 3With the center of the connecting shell 3 as the rotation center O, the distance between the rotation center and the adjustment groove 21 is r, and the distance between the rotation center and the light guide ring is R, where the value of R is greater than the value of r. Therefore, if the main adjustment ring is assembled with the connecting shell 3, the value of r is used as the rotation radius, while if the light guide ring is assembled with the connecting shell 3, the value of R is used as the rotation radius. Thus, this application uses the value of r as the rotation radius, requiring less rotation space than using the value of R as the rotation radius. With less required rotation space, the overall lamp body volume can also be smaller.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
