Detailed Description
In order that the invention may be more fully understood, reference will now be made to the following description. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Examples
Referring to fig. 1, the present invention provides a polyhedral reflective member 100 having a parabolic shape, the polyhedral reflective member 10 is formed by sequentially connecting a plurality of reflective rings 20, and each reflective ring 20 is formed by connecting a plurality of reflective mirrors 30.
In the polyhedral reflecting component, the angle of the reflector 30 of each layer is slightly adjusted compared with that of a smooth paraboloid, and the light rays in different areas are reflected by different reflectors 30, so that the light ray angles of all the areas are adjusted, the brightness of the middle and the edge of the reflected light rays is balanced, and the uniformity of the reflected light rays is improved.
The inner layer of the polyhedral reflective element 10 is a reflective surface with a reflective coating and the outer layer has no reflective effect. For example, the inner layer can be coated with a layer having a reflecting effect, such as a silver coating or a lithium coating.
The number of layers of the reflective ring 20 can be determined according to the preparation process, generally 3-8 layers can meet the requirement of uniform light emission, the number of layers can be selected according to the angle setting of each layer in 3-8 layers to meet the requirement of uniform light emission, and the more the number of layers, the more complex the process, the more difficult the preparation and formation.
For example, the polyhedral reflective element 100 includes three reflective rings 20, four reflective rings 20, five reflective rings 20, or more reflective rings 20, which can be selected according to the light emitting requirement, the angle of the reflective rings 20, and the condition of the process equipment.
In one embodiment, the same layer of reflective ring 20 is formed by a plurality of identical mirrors 30 connected together. The brightness of the position of the light reflected by each ring surface can be ensured to be the same, so that the light is more uniform.
In one embodiment, the number of the reflectors 30 of each layer of the reflective ring 20 is even, and the reflectors are arranged symmetrically. The even number of symmetrically arranged reflectors 30 can ensure that the parabolic polyhedral reflecting component 10 is easier to process and easier to align to form a paraboloid, and emergent ray bundles are symmetrically arranged, so that emergent rays are more uniform. In this embodiment, the number of the mirrors 30 of each layer of the reflective ring 20 is 16.
Of course, in other embodiments, the number of the mirrors 30 of the same layer of the reflective ring 20 may be an odd number, and the effect of uniform light may be achieved, but the effect is not as good as that of the even number.
In one embodiment, when the number of the mirrors 30 of each layer of the reflective ring 20 is the same, the sizes of the mirrors 30 of the reflective rings 20 of different layers are sequentially increased from the center of the polygonal reflective member 10 to the outside. Of course, the reflectors 30 of different layers of reflective rings 20 may have the same size, and since the polygonal reflective member 10 is a paraboloid, the number of reflectors 30 of each layer of reflective ring 20 is different.
Referring to fig. 1, in an embodiment, the reflectors 30 of the outermost reflective ring 20 of the polygonal reflective member 10 are pentagonal, and the reflectors 30 of the remaining reflective rings 20 are hexagonal. The hexagonal shaped mirrors 30 are easier to interconnect and the manufacturing process is simpler. Of course, each layer of mirrors 30 may be other shapes, such as pentagonal.
In one embodiment, the reflector 30 is a conical cylindrical reflector, which is more easily formed as a paraboloid. Of course, the reflector may have other shapes, and the effect of reflection may be achieved.
In one embodiment, the angles between the reflective surfaces of the reflectors 30 of each reflective ring 20 and the central axis of the polygonal reflective member 10 are different, and the angles between the reflectors 30 of the same reflective ring 20 and the central axis of the polygonal reflective member 10 are the same. The angles between the reflecting rings 20 of each layer are different, so that the parabolic shape can be quickly formed, the light rays reaching the reflecting rings 20 of each layer have different reflecting angles, and the emergent angles of the light rays at the center and the light rays at the edges are adjusted, so that the emergent light rays are more uniform. The angles of the reflectors 30 of the reflective rings 20 on the same layer are the same, so that the angles of the light rays on each ring surface are the same, the outgoing angle difference of the light rays on each layer is 0, and the outgoing uniformity of the light rays can be ensured.
The smaller the angle between the reflecting surface of the reflector 30 of each reflecting ring 20 and the central axis of the polygonal reflecting component 10 is, the smaller the reflected light spot is, and if a large light spot is desired to be obtained and the uniformity of the light spot is also desired to be ensured, the angle between the reflecting surface of the reflector 30 of each reflecting ring 20 and the center of the polygonal reflecting component 10 needs to be controlled within a certain range.
In one embodiment, the angle between the reflective surface of the mirror 30 of the first layer of reflective rings 20 and the center of the polygonal reflective member 10 is 76-77 degrees, measured outward from the center of the polygonal reflective member 10. The angle can adjust the emergent angle of the light at the position to uniformly emit light, and a paraboloid is easily formed.
In one embodiment, the angle between the reflective surface of the mirror 30 of the second layer of reflective ring 20 and the center of the polygonal reflective element 10 is 66-67 degrees, measured outward from the center of the polygonal reflective element 10. The angle can adjust the emergent angle of the light at the position to uniformly emit light, and a paraboloid is easily formed.
In one embodiment, the angle between the reflective surface of the mirror 30 of the third reflective ring 20 and the center of the polygonal reflective member 10 is 58-59 degrees from the center of the polygonal reflective member 10. The angle can adjust the emergent angle of the light at the position to uniformly emit light, and a paraboloid is easily formed.
In one embodiment, the angle between the reflective surface of the mirror 30 of the fourth layer of reflective ring 20 and the center of the polygonal reflective member 10 is 48 to 49 degrees, measured outward from the center of the polygonal reflective member 10. The angle can adjust the emergent angle of the light at the position to uniformly emit light, and a paraboloid is easily formed.
In one embodiment, the angle between the reflective surface of the reflector 30 of the fifth layer reflective ring 20 and the center of the polygonal reflective member 10 is 39-40 degrees from the center of the polygonal reflective member 10. The angle can adjust the emergent angle of the light at the position to uniformly emit light, and a paraboloid is easily formed.
In one embodiment, the angle between the reflective surface of the mirror 30 of the sixth layer of reflective ring 20 and the center of the polygonal reflective member 10 is 29-30 degrees, measured outward from the center of the polygonal reflective member 10. The angle can adjust the emergent angle of the light at the position to uniformly emit light, and a paraboloid is easily formed.
The angles of the reflection rings 20 from the first layer to the sixth layer are matched with each other, and after the light emitted at each angle is adjusted, the brightness of the light at the center and the edge can be ensured to be consistent, so that the purpose of uniform light emission can be achieved by using the six layers of reflection rings 20.
In the present embodiment, the angle between the reflection surface of the mirror 30 of the first-layer reflection ring 20 and the center of the polygonal reflection member 10 is 76.02 degrees, the angle between the reflection surface of the mirror 30 of the second-layer reflection ring 20 and the center of the polygonal reflection member 10 is 66.76 degrees, the angle between the reflection surface of the mirror 30 of the third-layer reflection ring 20 and the center of the polygonal reflection member 10 is 58.22 degrees, the angle between the reflection surface of the mirror 30 of the fourth-layer reflection ring 20 and the center of the polygonal reflection member 10 is 48.57 degrees, the angle between the reflection surface of the mirror 30 of the fifth-layer reflection ring 20 and the center of the polygonal reflection member 10 is 39.82 degrees, and the angle between the reflection surface of the mirror 30 of the sixth-layer reflection ring 20 and the center of the polygonal reflection member 10 is 29.68 degrees.
Referring to fig. 3, the preferred embodiment of the present invention employs six layers of reflective rings 20, wherein the angle of each layer of reflective ring 20 is a fixed value, and the polyhedral reflective element 10 with a specific angle is formed, so as to ensure uniform brightness of light at the center and edge, thereby achieving uniform light emission.
Referring to fig. 2, the present invention further provides a reflective lighting device 200, which includes a housing 40, a light emitter 50, and the above-mentioned polygonal reflective component 100, wherein the polygonal reflective component 100 is installed in the housing 40, a mounting hole 11 is formed in the center of the polygonal reflective component 10, and the light emitter 50 is installed in the mounting hole 11. The reflective lighting device combines the polyhedral reflective component 100, and the emitted light is uniform.
The reflective lighting device 200 may be a lighting device such as a flashlight, and the polyhedral reflective member 100 and the housing 40 may be mounted in the same manner as a conventional flashlight housing and a reflector.
