All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like, indicate orientations and positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the equipment or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be considered as limiting the present invention.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.
Referring to fig. 1, fig. 2 and fig. 3, wherein fig. 3 is a cross-sectional view taken along a section line a-a' of fig. 1, in an embodiment of the present invention, the lens 1 includes an incident portion 11 and an emergent portion 12, wherein the incident portion 11 is located on an incident side of the lens 1, and the emergent portion 12 is located on an emergent side of the lens 1.
The side surface of the light incident portion 11 has a plurality of ridges 111 (only one ridge is shown in the figure) for dividing the side surface of the light incident portion 11 into a plurality of polygons which are sequentially connected. Preferably, the ridges 111 are uniformly distributed on the side surface of the light incident portion 11.
Optionally, the bottom surface of the light incident portion 11 is an arc surface, so that the light emergent portion 12 forms a convex lens at the bottom surface of the light incident portion 11.
Optionally, the bottom surface of the light incident portion 11 includes a plurality of closely arranged polygonal refraction portions 112 (only one is labeled in the figure).
Preferably, each of the polygonal refracting parts 112 is hexagonal.
Preferably, each of the polygonal refracting parts 112 is closely arranged to approximately form a curved surface.
The light outgoing portion 12 entirely surrounds the side surface and the bottom surface of the light incoming portion 11. When the light enters the light emergent portion 12 from the light incident portion 11, the light is refracted, that is, the refractive index of the light incident portion 11 is different from that of the light emergent portion 12.
The light reflecting portion 13 entirely surrounds the side surface of the light emitting portion 12, and the light reflecting portion 13 is, for example, a light reflecting film.
As can be seen from the above description, the light emitted from the light source enters the light incident portion 11, is transmitted through the light incident portion 11, is refracted at the boundary between the light incident portion 11 and the light emergent portion 12, and then enters the light emergent portion 12. If the angle of the light is smaller than a critical angle, the light can be emitted from the bottom surface of the light emitting portion 12. If the angle of the light is greater than a critical angle, the light reaches the reflective portion 13 after being totally reflected at the bottom of the light-emitting portion 12, and is reflected again to change the transmission direction. After a series of transmissions in the light exit part 12 and/or the light entrance part 11, the light beam reaches the bottom surface of the light exit part 12 again, and if the angle of the light beam is smaller than the critical angle, the light beam is emitted from the bottom surface of the light exit part 12; if the angle of the light is still greater than the critical angle, the light will be totally reflected again at the bottom of the light-emitting portion 12. Accordingly, the light beams emitted from the bottom surface of the light emitting portion 12 all have a small angle. Therefore, the light emitted by the light source can obtain light with a smaller exit angle after passing through the lens 1 described in this embodiment, and thus, the user requirements in a specific scene can be met.
As can be seen from the above description, by properly designing parameters such as the thickness, the width, and the refractive index of the light emergent portion 12, the light emergent angle of the lens 1 can be a desired angle for a user. In particular, the exit angle of the lens 1 is 12 °, 25 ° or 36 °.
In an embodiment of the utility model, the light incident portion 1 is a blind hole opened on the light incident side of the lens 1.
Referring to fig. 4, 5 and 6, in an embodiment of the utility model, the light emitting portion 12 includes a first light emitting body 121, a second light emitting body 122 and a bottom light transmissive body 123. The first light-emitting body 121 is located on the light incident side of the lens 1, and a radial cross section of the first light-emitting body 121 is a circular ring, where the radial cross section is a cross section obtained by cutting along a radial direction of the first light-emitting body 121. The second light-emitting body 122 is located on the light-emitting side of the lens 1, a radial cross section of the second light-emitting body 122 is a circular ring and/or a circle, and a radial dimension of the second light-emitting body 122 is greater than a radial dimension of the first light-emitting body 121. The bottom light-transmitting body 123 is circular and is located on the bottom surface of the second light-emitting body.
Preferably, the first light emitting body 121, the second light emitting body 122, and the bottom light transmissive body 123 are integrally formed.
Preferably, a side surface of the first light-emitting body 121 is an arc surface, and/or a side surface of the second light-emitting body 122 is an arc surface.
Preferably, the bottom light-transmitting body 123 includes a plurality of polygonal light-transmitting sub-bodies 1231 (only one is labeled in the figure) arranged closely, and the polygonal light-transmitting sub-bodies 1231 are, for example, hexagonal.
The utility model also provides a lamp. Referring to fig. 7, in an embodiment of the utility model, the lamp 2 includes a light source 21 and a lens 22 as shown in fig. 1, and the light source 21 is disposed on a light incident side of the lens 22.
The lens comprises an incident part, an emergent part and a reflecting part, wherein the incident part is positioned on the incident side of the lens, the side surface of the incident part is provided with a plurality of ridge lines, the emergent part completely surrounds the side surface and the bottom surface of the incident part, the reflecting part completely surrounds the side surface of the emergent part, and light rays are refracted when entering the emergent part from the incident part. Therefore, in practical applications, after passing through the light incident portion, the light emitted by the light source is refracted to form refracted light, the refracted light enters the light emergent portion, when the refracted light reaches the bottom surface of the light emergent portion through transmission inside the light emergent portion, if the angle of the refracted light is too large, the refracted light is totally reflected at the bottom surface of the light emergent portion, and only the light with a smaller angle can be emitted from the bottom surface of the light emergent portion. Therefore, the light emitted by the light source can obtain light with a smaller emergent angle after passing through the lens, so that the user requirements under a specific scene can be met.
In addition, the lens has uniform light emitting area and more ultrathin size, and can effectively and fully utilize light efficiency in a smaller space.
In conclusion, the present invention effectively overcomes various disadvantages of the prior art and has high industrial utilization value.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the utility model. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
