Description

Technical Field

[0001] The present application relates to the field of lighting, and in particular to an optical element and a lamp. Background Art

[0002] In the field of lighting, such as the fishing industry, it is necessary to irradiate sufficient intensity of light in the fishing area to attract fish to gather; in other industries, such as the stage, it is also necessary to cover the entire venue with light. Therefore, in order to achieve the light intensity in this specified range, high-power lamps are usually used to irradiate to meet the light requirements from a distance. Taking the fishing industry as an example, high-power metal halide lamps and some LED fishing lights are used for irradiation; however, this metal halide lamp emits light at 360 degrees, and the effective utilization rate of light is low. Some LED fishing lights on the market use street lamp lenses for light distribution, but there is less light near the boat and near the bottom. After adjusting the light by rotating the angle, although the light near the boat and near the bottom is improved, it also sacrifices some light far from the boat; some LED fishing lights use transparent covers for light distribution, with a small angle, and the irradiation range on the sea level is not wide, and the LED light cannot be fully utilized within the expected irradiation range, resulting in low light utilization. Summary of the invention

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, an optical element and a lamp are proposed, which can improve the effective utilization rate of light from a light-emitting part in the lamp.

[0004] According to an optical element of an embodiment of the first aspect of the present application, the optical element includes:

[0005] Lens units, at least two of which are provided, each of which is provided with a receiving cavity at the bottom, and the receiving cavity is used to set a light-emitting component; the lens unit is used to generate an asymmetric light beam from the light emitted by the light-emitting component; the asymmetric light beams emitted by multiple lens units are combined to obtain an output light beam with a preset irradiation range.

[0006] According to the above-mentioned embodiment of the present application, at least the following beneficial effects are achieved: by setting a plurality of lens units, a plurality of asymmetric light beams can be generated, and by adjusting the polarization angle of the light beam emitted by each lens unit, asymmetric light beams with different polarization angles can be obtained. At this time, the range of the area to be irradiated can be divided into a plurality of sub-irradiation areas, so that each asymmetric light beam is deflected into the corresponding sub-irradiation area. Compared with the traditional lighting method, since the light is more fully and effectively utilized in the present application, the effective utilization rate of the light of the light-emitting part in the lamp can be improved.

[0007] According to an optical element of some embodiments of the first aspect of the present application, the bottom edges of every two adjacent lens units are connected to each other. By connecting the bottom edges of every two adjacent lens units to each other, the installation convenience of the optical element can be improved.

[0008] According to an optical element of some embodiments of the first aspect of the present application, one of the lens units is a first lens unit, an outer surface of the first lens unit is provided with a first exit convex surface and a second exit convex surface; a cavity wall of the accommodating cavity of the first lens unit is provided with a first incident concave surface and a second incident concave surface;

[0009] The curvature of the first emission convex surface is greater than the curvature of the second emission convex surface;

[0010] The curvature of the first incident concave surface is smaller than the curvature of the second incident concave surface; the first incident concave surface is arranged opposite to the first exit convex surface; the first incident concave surface is used to refract the light toward the first exit convex surface and then emit it; the second incident concave surface is used to refract the light toward the second exit convex surface and then emit it.

[0011] Therefore, by refracting the light from the first incident concave surface with a smaller curvature to the first exit convex surface with a larger curvature; and refracting the light from the second incident concave surface with a larger curvature to the second exit convex surface with a smaller curvature, the angle between the light deflection angle of the light emitting component arranged in the first lens unit and the center line of the light entrance of the accommodating cavity is made smaller, so that the refracted light can be concentrated in the area at the far end of the illumination range of the optical element.

[0012] In an optical element according to some embodiments of the first aspect of the present application, one of the lens units is a second lens unit, a cavity wall of the accommodating cavity of the second lens unit is sequentially provided with a third incident concave surface, a first incident convex surface and a first incident plane; an outer surface of the second lens unit is sequentially provided with a third total internal reflection plane, a first total internal reflection plane, a first exit plane, a second total internal reflection plane and a second exit plane;

[0013] The first incident plane is arranged opposite to the second exit plane; the third incident concave surface is used to refract light toward the third total internal reflection plane to eliminate stray light; the first incident convex surface is used to refract light toward the first total internal reflection surface or the second total internal reflection surface, so that the light refracted toward the first total internal reflection surface is totally reflected to the first exit plane and then emitted, and the light refracted toward the second total internal reflection surface is totally reflected to the second exit plane and then emitted; the first incident plane is used to refract light toward the second exit plane and then emit.

[0014] Therefore, by arranging the first total internal reflection surface at the outermost side of the second lens unit and arranging the second total internal reflection surface at the middle position of the second lens unit, the light refracted by the second lens unit is concentrated on one side of the second total internal reflection surface and between the first total internal reflection surface and the second total internal reflection surface, so that the light of the light-emitting component arranged in the first lens unit is deflected to the area close to the illumination range of the optical element.

[0015] According to an optical element of some embodiments of the first aspect of the present application, an adjustment plane is further provided on the outer surface of the second lens unit, and the adjustment plane is provided between the first exit plane and the second total internal reflection plane. By providing the adjustment plane, the inclination angle of the first exit plane can be adjusted, so that the angle between the light refracted from the second lens unit and the center line of the light inlet of the accommodating cavity can be adjusted.

[0016] According to some embodiments of the first aspect of the present application, in an optical element, one of the lens units is a third lens unit, a cavity wall of the accommodating cavity of the third lens unit is sequentially provided with a second incident plane and a fourth incident concave surface, and an outer surface of the third lens unit is sequentially provided with a third total internal reflection surface, a third exit plane, and a first exit concave surface;

[0017] The second incident plane is arranged opposite to the third total internal reflection surface; the second incident plane is used to refract the light toward the third total internal reflection surface, so that the light is totally reflected to the third exit plane and then emitted; the fourth incident concave surface is used to refract the light toward the first exit concave surface and then emit it.

[0018] Therefore, by arranging the third emission plane, the first emission concave surface and the third emission convex surface on one side of the third total internal reflection surface, the incident light can be deflected along one side of the third total internal reflection surface, so that the light refracted by the third lens unit can be concentrated in the middle area of ​​the irradiable range of the optical element.

[0019] According to an optical element of some embodiments of the first aspect of the present application, the outer surface of the third lens unit is also provided with a third exit convex surface, and the third exit convex surface is set to a smooth surface or a rough surface; the third exit convex surface is set on the third exit plane and the first exit concave surface, and the third exit convex surface is set opposite to the fourth incident concave surface; the third exit convex surface is used to scatter the light incident from the fourth incident concave surface. By setting the third exit convex surface, the light refracted from the third exit convex surface can be scattered, so that the light emitted from the first exit concave surface and the adjacent lens unit can be evenly distributed.

[0020] A lamp according to an embodiment of the second aspect of the present application includes:

[0021] A lamp structure, the lamp structure comprising a light source panel;

[0022] A light source assembly, the light source assembly includes a plurality of light-emitting components and a light-transmitting unit, the light-transmitting unit is arranged on the light source plate, the light-transmitting unit includes a lens unit, a plurality of lens units are arranged, a receiving cavity is arranged at the bottom of each lens unit, and the light-emitting component is arranged in each receiving cavity; the lens unit is used to generate an asymmetric light beam from the light emitted by the light-emitting component; the asymmetric light beams emitted by the plurality of lens units are combined to obtain an output light beam with a preset irradiation range.

[0023] According to the above embodiments of the present application, at least the following beneficial effects are achieved: since the optical element of the present application has any technical feature of the optical element of the first aspect, it has all the beneficial effects of the optical element.

[0024] According to some embodiments of the second aspect of the present application, the center of the light-emitting surface of the light-emitting element coincides with the center line of the light entrance of the accommodating cavity, wherein the center line of the light entrance is perpendicular to the light source board. By aligning the center of the light-emitting surface with the center line of the light entrance of the accommodating cavity, the incident light is deflected along a preset angle.

[0025] According to the lamps of some embodiments of the second aspect of the present application, there are three lens units, which are respectively set as a first lens unit, a second lens unit and a third lens unit; the angle between the light refracted by the first lens unit and the light source board is in the range of 60 to 110 degrees; the angle between the light refracted by the second lens unit and the light source board is in the range of 0 to 50 degrees; the angle between the light refracted by the third lens unit and the light source board is in the range of 30 to 70 degrees. By setting three lens units, the adjacent area, the middle area and the distant area of ​​the lamp installation location (such as a fishing boat) can be concentratedly illuminated respectively, saving light energy while obtaining a better lighting effect.

[0042] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0043] In the description of the present application, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0044] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0045] Refer to the following Figures 1 to 7 The optical element and the lamp of the present application are described.

[0046] like Figure 1 Optical components shown include:

[0047] The lens unit 100 is provided with at least two lens units 100, and a receiving cavity 110 is provided at the bottom of each lens unit 100, and the receiving cavity 110 is used to set the light-emitting component 620; the lens unit 100 is used to generate an asymmetric light beam from the light emitted by the light-emitting component 620; the asymmetric light beams emitted by multiple lens units 100 are combined to obtain an output light beam with a preset irradiation range.

[0048] It should be noted that the light emitting element 620 of each lens unit 100 may be arranged differently and adjusted according to the required irradiation distance and intensity.

[0049] It should be noted that the number of lens units 100 can be set according to the range of the emitted light beam to be irradiated.

[0050] It should be noted that an asymmetric light beam means that the emitted light has a certain degree of deflection. When all the light is concentrated in a specified area, the intensity of the illuminated area can be increased. Compared with a lens unit 100 without deflection, the lens unit 100 that generates an asymmetric light beam requires fewer light sources for the same illumination effect, thus effectively improving the effective utilization rate of the light source.

[0051] It should be noted that the light emitting element 620 , i.e. the light source, is arranged at the center line of the light entrance of the accommodating cavity 110 , i.e., a line perpendicular to the midpoint of the line connecting the two ends of the bottom of the accommodating cavity 110 on the same cross section of the lens unit 100 .

[0052] It should be noted that the irradiation range refers to the range covered by the light emitted by the optical element.

[0053] Therefore, by setting a plurality of lens units 100, a plurality of asymmetric light beams can be generated. At this time, by adjusting the polarization angle of the output light beam of each lens unit 100, asymmetric light beams with different polarization angles can be obtained. At this time, the range of the area to be irradiated can be divided into a plurality of sub-irradiation areas, so that each asymmetric light beam is deflected into a corresponding sub-irradiation area. Compared with the traditional lighting method, the light in the present application is more fully and effectively utilized, thereby improving the effective utilization rate of the light of the light emitting element 620 in the lamp.

[0054] It can be understood that the bottom edges of every two adjacent lens units 100 are connected to each other. By connecting the bottom edges of every two adjacent lens units 100 to each other, the installation convenience of the optical element can be improved.

[0055] It should be noted that, in some embodiments, the bottom edges of every two adjacent lens units 100 are integrally formed and processed from the same plate material. In other embodiments, each lens unit may also be made of different plates and connected together by bonding or clamping.

[0056] It can be understood that, Figure 1 , Figure 2 and Figure 3 As shown, one of the lens units 100 is a first lens unit 200 , and the outer surface of the first lens unit 200 is provided with a first convex surface 221 and a second convex surface 222 ; the cavity wall of the accommodating cavity 110 of the first lens unit 200 is provided with a first concave surface 211 and a second concave surface 212 .

[0057] The curvature of the first convex surface 221 is greater than the curvature of the second convex surface 222 .

[0058] The curvature of the first incident concave surface 211 is smaller than the curvature of the second incident concave surface 212; the first incident concave surface 211 is arranged opposite to the first exit convex surface 221; the first incident concave surface 211 is used to refract the light toward the first exit convex surface 221 and then emit it; the second incident concave surface 212 is used to refract the light toward the second exit convex surface 222 and then emit it.

[0059] It should be noted that the greater the curvature, the greater the convexity of the convex surface and the greater the curvature of the concave surface.

[0060] It should be noted that, in some embodiments, the curvature at the connection between the first output convex surface 221 and the second output convex surface 222 is continuous, and at this time, the outer surface of the first lens unit 200 forms a smooth curved surface; the curvature at the connection between the first incident concave surface 211 and the second incident concave surface 212 is continuous, and the cavity wall of the accommodating cavity 110 of the first lens unit 200 forms a smooth curved surface. By forming the outer surface of the first lens unit 200 and the cavity wall of the accommodating cavity 110 into smooth curved surfaces, the light emitted by the light source is accurately distributed.

[0061] Therefore, by refracting the light from the first incident concave surface 211 with a smaller curvature to the first exit convex surface 221 with a larger curvature; and refracting the light from the second incident concave surface 212 with a larger curvature to the second exit convex surface 222 with a smaller curvature, the angle between the light deflection angle of the light emitting component 620 arranged in the first lens unit 200 and the center line of the light entrance of the accommodating cavity 110 is made smaller, so that the refracted light can be concentrated in the area at the far end of the illumination range of the optical element.

[0062] It should be noted that the distal region of the irradiation range of the optical element refers to a continuous region farthest from the irradiation range of the optical element.

[0063] It can be understood that, Figure 1 and Figure 4 As shown, one of the lens units 100 is a second lens unit 300, and the cavity wall of the accommodating cavity 110 of the second lens unit 300 is sequentially provided with a third incident concave surface 311, a first incident convex surface 312 and a first incident plane 313; the outer surface of the second lens unit 300 is sequentially provided with a third total internal reflection plane 351, a first total internal reflection plane 321, a first exit plane 322, a second total internal reflection plane 323 and a second exit plane 324;

[0064] The first incident plane 313 and the second exit plane 324 are arranged opposite to each other; the third incident concave surface 311 is used to refract light toward the third total internal reflection plane 351 to eliminate stray light; the first incident convex surface 312 is used to refract light toward the first total internal reflection surface 321 or the second total internal reflection surface 323, so that the light refracted toward the first total internal reflection surface 321 is totally reflected to the first exit plane 322 and then emitted, and the light refracted toward the second total internal reflection surface 323 is totally reflected to the second exit plane 324 and then emitted; the first incident plane 313 is used to refract light toward the second exit plane 324 and then emit.

[0065] It should be noted that the connection between the first incident convex surface 312 and the first incident plane 313 is a smooth transition. Some of the light incident from the first incident convex surface 312 is refracted toward the first total internal reflection surface 321 , and some of the light is refracted toward the second total internal reflection surface 323 .

[0066] Therefore, by setting the first total internal reflection surface 321 at the outermost side of the second lens unit 300 and setting the second total internal reflection surface 323 at the middle position of the second lens unit 300, the light refracted by the second lens unit 300 is concentrated on one side of the second total internal reflection surface 323 and between the first total internal reflection surface 321 and the second total internal reflection surface 323, so that the light of the light-emitting element 620 arranged in the second lens unit 300 is deflected to the area close to the illumination range of the optical element.

[0067] It should be noted that the area near the illumination range of the optical element refers to the continuous illumination area corresponding to the illumination range closest to the installation position of the optical element.

[0068] It should be noted that the total internal reflection surface can reflect the incident light. Taking the second total internal reflection surface 323 as an example, when the incident light enters from the first incident convex surface 312 and is refracted to the second total internal reflection surface 323 in the second lens unit 300, the incident light will be reflected to the second exit plane 324 and then emitted.

[0069] It can be understood that, Figure 4 As shown, the outer surface of the second lens unit 300 is further provided with an adjustment plane 325, and the adjustment plane 325 is provided between the first exit plane 322 and the second total internal reflection surface 323. By providing the adjustment plane 325, the inclination angle of the first exit plane 322 can be adjusted, so that the angle between the light refracted from the second lens unit 300 and the center line of the light entrance of the accommodating cavity 110 can be adjusted.

[0070] It should be noted that the first exit plane 322 determines the farthest distance that the second lens unit 300 can illuminate, because by adjusting the angle of the first exit plane 322, the farthest distance that the second lens unit 300 can illuminate can be adjusted; at this time, the light refracted by the first exit plane 322 and the second exit plane 324 is mixed and concentrated in the area in the middle of the irradiation range of the lamp.

[0071] It can be understood that, Figure 1 and Figure 5 As shown, one of the lens units 100 is the third lens unit 400, and the cavity wall of the accommodating cavity 110 of the third lens unit 400 is sequentially provided with a second incident plane 411 and a fourth incident concave surface 412, and the outer surface of the third lens unit 400 is sequentially provided with a third total internal reflection surface 421, a third exit plane 422, and a first exit concave surface 423.

[0072] The second incident plane 411 is arranged opposite to the third total internal reflection surface 421; the second incident plane 411 is used to refract the light toward the third total internal reflection surface 421, so that the light is totally reflected to the third exit plane 422 and then emitted; the fourth incident concave surface 412 is used to refract the light toward the first exit concave surface 423 and then emit it.

[0073] Therefore, by arranging the third emission plane 422, the first emission concave surface 423 and the third emission convex surface 424 on one side of the third total internal reflection surface 421, the incident light can be deflected along one side of the third total internal reflection surface 421. Thus, the light emitted by the third lens unit 400 can be concentrated in the middle area of ​​the irradiable range of the optical element.

[0074] It should be noted that the middle area of ​​the irradiable range of the optical element is a continuous area where the irradiation range does not overlap with the edge of the irradiation range.

[0075] It can be understood that, Figure 5 As shown, the outer surface of the third lens unit 400 is also provided with a third emission convex surface 424, and the third emission convex surface 424 is set to a smooth surface or a rough surface; the third emission convex surface 424 is set on the third emission plane 422 and the first emission concave surface 423, and the third emission convex surface 424 is arranged opposite to the fourth incident concave surface 412; the third emission convex surface 424 is used to scatter the light incident from the fourth incident concave surface 412. By setting the third emission convex surface 424, the light refracted from the third emission convex surface 424 can be scattered, so that the light emitted from the first emission concave surface 423 and the adjacent lens unit 100 can be evenly distributed.

[0076] It should be noted that when the third lens unit 400 is disposed adjacent to the second lens unit 300 or the first lens unit 200, the light scattered by the third convex output surface 424 makes the light refracted between two adjacent lens units 100 evenly distributed, resulting in better visual effect.

[0077] It should be noted that the first lens unit 200, the second lens unit 300, and the third lens unit 400 can be arranged in any combination to meet different illumination requirements. In some embodiments, a connection portion is provided on both sides of the accommodating cavity 110 of one or more of the first lens unit 200, the second lens unit 300, and the third lens unit 400, so that the cavity space formed by the accommodating cavity 110 and the light source board 610 is larger, so that the shape of the incident surface of the accommodating cavity 110 can be more varied.

[0078] In some embodiments, such as sea level 720, when the optical element is provided with three lens units 100, and they are respectively provided as a first lens unit 200, a second lens unit 300, and a third lens unit 400, at this time, the illumination effect is as follows: Figure 6 As shown, the light source panel is arranged perpendicular to the sea level 720.

[0079] According to a second aspect of the present application, a lamp is Figure 7 The lamps include:

[0080] A lamp structure, the lamp structure includes a light source panel 610;

[0081] The light source assembly includes a plurality of light-emitting components 620 and a light-transmitting unit. The light-transmitting unit is arranged on the light source plate 610. The light-transmitting unit includes a lens unit 100. A plurality of lens units 100 are arranged. A receiving cavity 110 is arranged at the bottom of each lens unit 100. Each receiving cavity 110 is arranged with a light-emitting component 620. The lens unit 100 is used to generate an asymmetric light beam from the light emitted by the light-emitting component 620. The asymmetric light beams emitted by the plurality of lens units 100 are combined to obtain an output light beam with a preset irradiation range.

[0082] Therefore, since the optical element of the present application has any technical feature of the optical element of the first aspect, it has all the beneficial effects of the optical element.

[0083] It should be noted that, in some applications, the lamp structure further includes a lamp housing, the lamp housing is provided with a light source assembly accommodating cavity, the light source board 610 is fixedly arranged in the light source assembly accommodating cavity, and the lens unit 100 and the light emitting member 620 are arranged on the light source board 610. Moreover, a heat dissipation channel is formed between the outer surface of the lens unit 100 and the cavity wall of the light source assembly accommodating cavity, so that the heat dissipation effect of the light source assembly is good, and the service life of the lamp is extended.

[0084] It can be understood that, Figure 7 As shown, preferably, the center of the light-emitting surface of the light-emitting element 620 coincides with the center line of the light entrance of the accommodating cavity 110, wherein the center line of the light entrance is perpendicular to the light source plate. By aligning the center of the light-emitting surface with the center line of the light entrance of the accommodating cavity 110, the incident light is deflected along a preset angle.

[0085] It should be noted that the light emitting element 620 can be configured as lamp beads, which can be arranged in one row or multiple rows and can be arranged according to the intensity of the deflected light. The lamp beads can be selected from LED lamp beads of models such as 7070, 5050, 3030 or 2835 to achieve better illumination effect.

[0086] It can be understood that there are three lens units, which are respectively set as the first lens unit 200, the second lens unit 300 and the third lens unit 400; the angle between the light refracted by the first lens unit 200 and the light source board is in the range of 60 to 110 degrees; the angle between the light refracted by the second lens unit 300 and the light source board is in the range of 0 to 50 degrees; the angle between the light refracted by the third lens unit 400 and the light source board is in the range of 30 to 70 degrees. By setting three lens units 100, the adjacent area, the middle area and the distant area of ​​the lamp installation location (such as a fishing boat) can be concentratedly illuminated respectively, saving light energy while obtaining a better lighting effect.

[0087] It should be noted that the lamp can be installed on a fishing boat or on a wall. When the lamp is installed on a fishing boat, Figure 7As shown, the light source panel 610 is fixed on the lamp stand of the fishing boat through the lamp housing. At this time, the light from the lens unit of the lamp is directed to the surroundings of the fishing boat, focusing on the adjacent area, middle area and distant area of ​​the fishing boat.

[0088] Reference below Figures 1 to 7 A fishing lamp according to an embodiment of the present application is described in detail with a specific embodiment.
