Abstract
Description
Technical Field
[0001] This invention relates to the field of lighting technology, and in particular to a beam lamp. Background Technology
[0002] Currently, to achieve both patterned and textured or fogging effects in beam lights, it is typically necessary to add textured optical plates and corresponding adjustment mechanisms, as well as fogging optical plates and corresponding adjustment mechanisms. For example, the "Stage Light" with announcement number CN113280307B includes a first turntable and a corresponding turntable switching component. The first turntable has special textures and / or patterns to produce dynamic effects similar to water ripples and fire patterns when rotated. It also includes a fogging adjustment mechanism to achieve a fogging effect.
[0003] Achieving both texture and fog effects on the same lamp requires the addition of optical components and drive adjustment mechanisms, resulting in complex internal components and high costs. Consequently, the lamp housing requires a larger capacity and higher costs, and the overall weight of the lamp also increases. Summary of the Invention
[0004] The technical problem to be solved by this invention is that existing lamps require additional optical components and driving adjustment mechanisms to achieve both texture and fogging effects, resulting in high lamp costs.
[0005] To solve the above-mentioned technical problems, the present invention provides a beam lamp, including a light source, a first turntable assembly, an effect switcher, a second turntable assembly and a focusing assembly arranged sequentially along a first main optical axis, wherein the first turntable assembly includes a first pattern sheet and the second turntable assembly includes a second pattern sheet;
[0006] The effect switcher includes an effect panel, the side of the effect panel facing the light source is a smooth surface, and the side of the effect panel away from the light source is a frosted textured surface.
[0007] The focusing assembly includes a focusing motor, a connector, a focusing lens, and a light-emitting lens. The focusing motor can drive the connector to move, thereby driving the focusing lens to move along the first main optical axis.
[0008] The beam lamp can switch between a fogging mode and a texture mode by adjusting the distance between the focusing lens and the light-emitting lens. When the focusing lens and the light-emitting lens work together with the effect sheet to image the first pattern sheet, the beam lamp is in the fogging mode. When the focusing lens and the light-emitting lens work together with the effect sheet to image the second pattern sheet, the beam lamp is in the texture mode.
[0009] Preferably, the effect switcher further includes a motion motor, the effect piece is disposed on the first main optical axis, and the motion motor can drive the effect piece to rotate about the first main optical axis.
[0010] Preferably, the effect switcher further includes a swing arm and a switching motor, the output shaft of the switching motor is connected to one end of the swing arm, and the other end of the swing arm is rotatably connected to the effect sheet.
[0011] Preferably, the effect switcher further includes a first transmission wheel, a first transmission belt, a second transmission wheel, a first gear, a second gear, and a third gear ring. The first transmission wheel is connected to the output shaft of the motion effect motor. The second transmission wheel is coaxially arranged and fixedly connected to the first gear. The second transmission wheel is rotatably connected to the output shaft of the switching motor. The first transmission belt connects the first transmission wheel and the second transmission wheel. The first gear meshes with the second gear. The second gear meshes with the third gear ring. The third gear ring is rotatably connected to the swing arm. The effect piece is mounted on the third gear ring.
[0012] Preferably, the diameter of the first patterned piece is in the range of 2mm to 4mm, and the diameter of the second patterned piece is in the range of 20mm to 30mm.
[0013] Preferably, the distance between the effect sheet and the first pattern sheet along the first main optical axis is a, and the distance between the effect sheet and the second pattern sheet along the first main optical axis is b, wherein a / b≥3.
[0014] Preferably, the first turntable assembly further includes a first disc body and a first motor. The first pattern piece is disposed on the first disc body, and the first motor can drive the first disc body to rotate, thereby switching each of the first pattern pieces onto the first main optical axis.
[0015] Preferably, the second turntable assembly further includes a second disc body, a second motor, a third motor, a planetary gear ring, and a sun gear. The number of planetary gear rings is the same as the number of second pattern pieces. The planetary gear rings are rotatably connected to the second disc body, and the second pattern pieces are mounted on the planetary gear rings. The second motor is used to drive the second disc body to rotate, thereby switching each of the second pattern pieces to the first main optical axis. The sun gear is rotatably connected to the second disc body and coaxially arranged with the second disc body. The sun gear meshes with each of the planetary gear rings. The third motor is used to drive the sun gear to rotate.
[0016] Preferably, there are two focusing motors and two connecting parts. The output shaft of each focusing motor is connected to one connecting part. The connecting part is a threaded rod. The focusing assembly also includes a limiting mounting part. The focusing lens is mounted on the limiting mounting part. The limiting mounting part has a threaded hole that is axially parallel to the first main optical axis. Each connecting part is threadedly connected to the limiting mounting part through the threaded hole.
[0017] Preferably, the light source is a laser light source.
[0018] The present invention provides a beam lamp, which, compared with the prior art, has the following advantages:
[0019] The system consists of a first turntable assembly, an effect switcher, a second turntable assembly, and a focusing assembly arranged sequentially. The effect switcher includes an effect sheet. The side of the effect sheet facing the light source (the light-incident surface) is smooth, while the side facing away from the light source (the light-emitting surface) has a frosted texture. In other words, the effect sheet has both a frosted and a textured structure. When the focusing lens is moved closer to the second turntable assembly, the combined focal length of the focusing lens and the light-emitting lens increases, imaging the first patterned image on the first main optical axis. The frosted structure on the effect sheet then produces a fogging effect, meaning the beam light is in fogging mode. When the focusing lens is moved closer to the light-emitting lens, the combined focal length of the focusing lens and the light-emitting lens decreases, imaging the second patterned image on the first main optical axis. The textured structure on the effect sheet then produces a textured effect, meaning the beam light is in texture mode. The frosted structure on the effect sheet can then produce a prism superposition effect, creating a shimmering effect. Therefore, the beam lamp of the present invention can achieve both fogging and texture effects through the effect switcher. Only the focusing lens needs to be adjusted to make the effect film present different effects, which greatly simplifies the lamp structure and reduces the lamp cost. Attached Figure Description

Detailed Implementation
[0025] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.
[0026] In the description of this invention, it should be understood that the terms "axial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.
[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0028] like Figures 1 to 3 As shown, a preferred embodiment of the present invention, a beam lamp 100, includes a light source 10, a first turntable assembly 20, an effect switcher 30, a second turntable assembly 40, and a focusing assembly 50 arranged sequentially along the same main optical axis, namely the first main optical axis X. The first turntable assembly 20 includes a first pattern sheet 21, and the second turntable assembly 40 includes a second pattern sheet 41.
[0029] The effect switcher 30 includes an effect plate 31. The side of the effect plate 31 facing the light source 10 is a smooth surface with a roughness of less than 0.01μm. The side of the effect plate 31 away from the light source 10 is a frosted texture surface, preferably with water ripples, fire ripples, etc.
[0030] The focusing assembly includes a focusing motor 51, a connector 52, a focusing lens 53, and a light-emitting lens 54. The focusing motor 51 can drive the connector 52 to move, thereby driving the focusing lens 53 to move along the first principal optical axis X. The principal optical axis of the light-emitting lens 54 is defined as the first principal optical axis X.
[0031] The beam lamp 100 can switch between a fogging mode and a texture mode by adjusting the distance between the focusing lens 53 and the light-emitting lens 54. When the focusing lens 53 and the light-emitting lens 54 work together with the effect sheet 31 to image the first pattern sheet 21, the beam lamp 100 is in a fogging mode. When the focusing lens 53 and the light-emitting lens 54 work together with the effect sheet 31 to image the second pattern sheet 41, the beam lamp 100 is in a texture mode.
[0032] Based on the above embodiment, the beam lamp 100 comprises a first turntable assembly 20, an effect switcher 30, a second turntable assembly 40, and a focusing assembly 50 arranged sequentially. The effect switcher 30 includes an effect plate 31. The side of the effect plate 31 facing the light source 10, i.e., the light-incident surface, is a smooth surface, while the side of the effect plate 31 facing away from the light source 10, i.e., the light-emitting surface, has a frosted texture. In other words, the effect plate 31 has both a frosted structure and a textured structure. When the focusing lens 53 is moved closer to the second turntable assembly 40, the combined focal length of the focusing lens 53 and the light-emitting lens 54 increases. When the first patterned image 21, located on the first principal optical axis X, is imaged, the frosted structure on the effect image 31 produces a fogging effect, meaning the beam lamp 100 is in fogging mode. When the focusing lens 53 is moved closer to the light-emitting lens 54, the combined focal length of the focusing lens 53 and the light-emitting lens 54 becomes shorter, imaged on the second patterned image 41, located on the first principal optical axis X. The textured structure on the effect image 31 produces a textured effect, meaning the beam lamp 100 is in texture mode. The frosted structure on the effect image 31 can then produce a prism superposition effect, creating a shimmering effect. Therefore, the beam lamp 100 of this invention achieves both fogging and textured effects through the effect switcher 30. Only the focusing lens 53 needs to be adjusted to allow the effect image 31 to present different effects, greatly simplifying the lamp structure and reducing lamp costs while retaining the corresponding functions.
[0033] Preferably, the effect switcher 30 also includes a motion motor 32. The effect piece 31 is disposed on the first main optical axis X. The motion motor 32 can drive the effect piece 31 to rotate around the first main optical axis X. Thus, when the beam lamp 100 is in texture mode, the rotation of the effect piece 31 gives a dynamic effect of texture rotation.
[0034] Preferably, the effect switcher 30 also includes a swing arm 33 and a switching motor 34. The output shaft of the switching motor 34 is connected to one end of the swing arm 33, and the other end of the swing arm 33 is rotatably connected to the effect sheet 31. Thus, when the beam light 100 does not require a fog effect or texture effect, it can drive the swing arm 33 to rotate via the switching motor 34 to cut out the effect sheet 31.
[0035] In some specific embodiments, the effect switcher 30 further includes a first transmission wheel 35, a first transmission belt 36, a second transmission wheel 371, a first gear 372, a second gear 38, and a third gear ring 39. The first transmission wheel 35 is connected to the output shaft of the motion effect motor 32. The second transmission wheel 371 is coaxially arranged and fixedly connected to the first gear 372. The second transmission wheel 371 is rotatably connected to the output shaft of the switching motor 34. The first transmission belt 36 connects the first transmission wheel 35 and the second transmission wheel 371. The first gear 372 meshes with the second gear 38, the second gear 38 meshes with the third gear ring 39, and the third gear ring 39 is rotatably connected to the swing arm 33. The effect piece 31 is mounted on the third gear ring 39. By setting the first transmission wheel 35, the first transmission belt 36, the second transmission wheel 371, the first gear 372, the second gear 38, and the third gear ring 39 to cooperate, it is possible to facilitate the effect piece 31 to cut into and out of the first main optical axis X and to rotate around the first main optical axis X.
[0036] Preferably, the diameter of the first patterned sheet 21 is in the range of 2mm to 4mm, more preferably 3mm, and the diameter of the second patterned sheet 41 is in the range of 20mm to 30mm, more preferably 26mm. The diameter range of the first patterned sheet 21 is selected to be much smaller than the diameter range of the second patterned sheet 41, so as to achieve a fogging effect on the first patterned sheet 21 and a texture effect on the second patterned sheet 41 respectively.
[0037] Preferably, the distance between the effect sheet 31 and the first pattern sheet 21 along the first principal optical axis X is a, and the distance between the effect sheet 31 and the second pattern sheet 41 along the first principal optical axis X is b, where a / b≥3. The effect sheet 31 is far away from the first pattern sheet 21 and close to the second pattern sheet 41, so as to achieve a fogging effect on the first pattern sheet 21 and a texture effect on the second pattern sheet 41, respectively.
[0038] Preferably, the first turntable assembly 20 further includes a first disc body 22 and a first motor 23. The first pattern piece 21 is disposed on the first disc body 22. The first motor 23 can drive the first disc body 22 to rotate, thereby switching each first pattern piece 21 to the first main optical axis X, so that different pattern pieces on the first disc body 22 can be imaged.
[0039] Preferably, the second turntable assembly 40 further includes a second disc body 42, a second motor 43, a third motor 44, a planetary gear ring 45, and a sun gear 46. The number of planetary gear rings 45 is the same as the number of second pattern pieces 41. The planetary gear rings 45 are rotatably connected to the second disc body 42, and the second pattern pieces 41 are mounted on the planetary gear rings 45. The second motor 43 is used to drive the second disc body 42 to rotate, thereby switching each second pattern piece 41 to the first main optical axis X. The second turntable assembly 40 preferably also includes a second transmission belt 47 and a third transmission wheel 48. The third transmission wheel 48 is fixedly connected to the second disc body 42 and is coaxially arranged with the second disc body 42. The second transmission belt 47 connects the output shaft of the second motor 43 to the third transmission wheel 48. The sun gear 46 is rotatably connected to the second disc body 42 and is coaxially arranged with the second disc body 42. The sun gear 46 meshes with each planetary gear ring 45. The third motor 44 is used to drive the sun gear 46 to rotate. The second turntable assembly 40 preferably also includes a third transmission belt 49, which connects the output shaft of the third motor 44 to the sun gear 46. By setting a second motor 43, a second transmission belt 47, and a third transmission wheel 48 to rotate the second disk 42, different second pattern pieces 41 are switched onto the first main optical axis X. By setting a third motor 44, a planetary gear ring 45, a sun gear 46, and a third transmission belt 49, the sun gear 46, which is rotatably connected to the second disk 42, rotates and drives each planetary gear ring 45 to rotate together. The second pattern pieces 41 installed in the planetary gear rings 45 also rotate, so that the second pattern pieces 41 on the first main optical axis X have a rotating dynamic effect when imaging.
[0040] Preferably, there are two focusing motors 51 and two connecting parts 52. The output shaft of each focusing motor 51 is connected to one connecting part 52, and the connecting part 52 is a threaded rod. The focusing assembly also includes a limiting mounting part 55, and the focusing lens 53 is mounted on the limiting mounting part 55. The limiting mounting part 55 has a threaded hole with its axis parallel to the first main optical axis X. Each connecting part 52 is threadedly connected to the limiting mounting part 55 through the threaded hole. By connecting the two focusing motors 51 to the connecting parts 52, which are threaded rods, the two motors drive the two threaded rods to rotate. The limiting mounting part 55 therefore moves along the axis of the threaded rods, and the focusing lens 53 moves along with it, thereby changing the combined focal length of the focusing lens 53 and the light-emitting lens 54.
[0041] Preferably, the light source 10 is a laser light source 10, thereby achieving a stronger beam effect.
[0042] like Figure 4 As shown, specifically, the beam lamp 100 also includes a housing 60, and all the above-mentioned components of the beam lamp 100 are installed in the housing 60. The shape and structure of the housing 60 are not limited to the examples in the accompanying drawings.
[0043] In summary, the embodiments of the present invention provide a beam lamp in which a first turntable assembly, an effect switcher, and a second turntable assembly are cleverly arranged sequentially along a first main optical axis. The effect switcher can achieve both fogging and texture effects. By simply adjusting the focusing lens to change the combined focal length, different effects can be achieved by coordinating the effect sheets, which greatly simplifies the lamp structure and reduces the lamp cost.
[0044] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
