It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 1-7, a light distribution assembly 210 is disclosed in an embodiment of the present invention, the disclosed light distribution assembly 210 includes a light diffusing element 211, a first light reflecting element 213, and a second light reflecting element 212; the first light reflection element 213 and the second light reflection element 212 are respectively arranged at two opposite sides of the light diffusion element 211, and a light distribution chamber with a flaring structure is formed among the first light reflection element 213, the light diffusion element 211 and the second light reflection element 212; the side of the light distribution chamber opposite the light diffusing element 211 is a flared end 214.
Meanwhile, the light diffusion member 211 is recessed toward one side of the flared end 214 to form a light source cavity 2110 in a groove structure, and the light source cavity 2110 includes a first diffusion portion 2111 facing the reflection surface of the first light reflection member 213, a second diffusion portion 2112 facing the flared end 214, and a third diffusion portion 2113 facing the reflection surface of the second light reflection member 212, that is, a portion of the light source cavity 2110 that can diffuse light to the reflection surface of the first light reflection member 213 is the first diffusion portion 2111, a portion of the light source cavity that can diffuse light to the flared end 214 is the second diffusion portion 2112, and a portion of the light source cavity 2110 that can diffuse light to the reflection surface of the second light reflection member 212 is the third diffusion portion 2113.
Based on the light distribution assembly 210 configured as described above, as shown in fig. 4, the light diffusion member 211 forms a light source cavity 2110 having a first diffusion portion 2111, a second diffusion portion 2112, and a third diffusion portion 2113, and the first diffusion portion 2111 faces the reflection surface of the first light reflection element 213, the second diffusion portion 2112 faces the flared end 214, and the third diffusion portion 2113 faces the reflection surface of the second light reflection element 212; therefore, most of the emergent light passing through the second diffusion portion 2112 can be directly emitted through the flared end 214, the emergent light passing through the first diffusion portion 2111 can be emitted from the flared end 214 after being controlled by the emission of the reflection surface of the first light reflection element 213, and the emergent light passing through the third diffusion portion 2113 can be emitted from the flared end 214 after being controlled by the reflection of the reflection surface of the second light reflection element 212, so that the batwing-shaped light distribution effect as shown in fig. 5 is achieved, the illumination uniformity in the irradiation area is improved, and the overlapping of a large area of light existing when multiple lamps are arranged is avoided. In which, the batwing curve shown in fig. 5 is a schematic view of the light distribution effect on the C0 ° cross section (i.e. a cross section passing through the central axis of the light source and perpendicular to the light diffusing element 211, such as the cross section shown in fig. 4) after passing through the light distribution module 210, and the drop-shaped curve is a schematic view of the light distribution effect on the C90 ° cross section (i.e. a cross section passing through the central axis of the light source and perpendicular to C0 °) without passing through the light distribution module 210 in the other two directions of the light diffusing element 211.
Therefore, compared with the existing lamp, the light distribution assembly 210 disclosed by the utility model can improve the illumination uniformity of the lighting lamp when a single lamp is used for illumination; in addition, when the lamps are arranged in a plurality of lamps, the arrangement number of the lamps can be reduced, so that the illumination cost is reduced, and the utilization rate of light is improved.
The light diffusion element 211 disclosed in the embodiment of the present invention can be a diffusion plate, a diffusion sheet, or a diffusion film, so that the first diffusion portion 2111, the second diffusion portion 2112, and the third diffusion portion 2113 formed by the light diffusion element 211 can interfere with light, change the original light distribution curve of the light source in the light source cavity 2110, and make the light beam of the light source mainly split into the three corresponding portions to be emitted from the light diffusion element 211; meanwhile, the first light reflecting element 213 and the second light reflecting element 212 may both adopt mirror panels or mirror aluminum reflectors and other existing mirror reflectors, so as to reflect the light emitted by the first diffusing part 2111 and the second diffusing part 2112, change the angle of the emitted light, control the light emitting direction, and achieve a batwing light distribution curve; the present invention does not limit the specific types of the light diffusion element 211, the first light reflection element 213, and the second light reflection element 212.
In order to make the light distribution assembly 210 form a symmetrically distributed batwing light distribution, the reflection surface of the first light reflection element 213 and the reflection surface of the second light reflection element 212 are symmetrically configured with respect to the central axis of the light source cavity 2110, that is, the first light reflection element 213 and the second light reflection element 212 are symmetrically disposed at two sides of the light diffusion element 211; in general, the light source may be located on the central axis of the light source cavity 2110, so that the reflective surface of the first light reflecting element 213 and the reflective surface of the second light reflecting element 212, which are symmetrically disposed, may better ensure the symmetric uniform distribution of illumination, facilitate the arrangement of the lamps and reduce the difficulty of the illumination arrangement when multiple lamps are arranged.
Of course, the arrangement direction between the reflection surface of the first light reflection element 213 and the reflection surface of the second light reflection element 212 may be an asymmetric structure, so that the light distribution forms an asymmetric batwing-shaped light distribution. For example, an angle between the reflection surface of the first light reflection member 213 and the central axis of the light source cavity 2110 is temporarily first defined as a first angle, and an angle between the reflection surface of the second light reflection member 212 and the central axis of the light source cavity 2110 is temporarily defined as a second angle; in general, there is a deviation of about 2 to 3 ° between the first angle and the second angle due to errors in assembling the light distribution unit 210, processing and manufacturing of each element, and the like.
The embodiment of the utility model discloses in grading subassembly 210, the plane can be both to the plane of reflection face of first light reflection component 213 and second light reflection component 212, also can be to the crooked curved surface of direction from the light distribution room, it can carry out corresponding design to the face type camber of plane or curved surface and make reflection light jet out according to the light-emitting direction that requires can.
Specifically, as shown in fig. 4, the reflection surface of the first light reflection element 213 and the reflection surface of the second light reflection element 212 are both curved surfaces that are curved away from the light distribution chamber, and the curved surfaces are curved surfaces that include an upper bending surface and a lower bending surface, so that the curved surfaces have two kinds of surface curvatures through the upper bending surface and the lower bending surface, and further, most of the light rays emitted by the second diffusion portion 2112 are emitted from the flared end 214 after being reflected by the lower bending surface, and are main light rays forming batwing light distribution, and a small part of the light rays are also emitted from the flared end 214 after being reflected by the upper bending plate, so as to reinforce the light intensity in the small-angle direction; therefore, compared with the single-surface curvature of a plane, the curved surface can achieve better light control effect.
Meanwhile, as a light emitting direction requirement of the reflected light of the bent surface, the surface curvature of the upper bent surface is designed to reflect the reflected light to a direction within 15 ° (an included angle between the reflected light and a central axis of the light source), and the surface curvature of the lower bent surface is designed to reflect the reflected light to a direction between 20 ° -30 °.
It is easy to understand that, in the light distribution assembly 210 disclosed in the embodiment of the present invention, in order to better improve the light control effect of the reflection surface, the reflection surface of the first light reflection element 213 and the reflection surface of the second light reflection element 212 may also be designed as a curved surface with multiple surface curvatures or a smooth arc-shaped curved surface; moreover, the surface curvature of the reflecting surface can be adjusted adaptively according to the specific light direction requirement of the reflected light; the embodiment of the present invention does not limit the specific shape of the reflective surface of the first light reflecting element 213 and the reflective surface of the second light reflecting element 212 and the specific surface curvature of the reflective surface.
In the light distribution module 210 disclosed in the embodiment of the present invention, as shown in fig. 6, the light source cavity 2110 may be a groove structure having a square cross-sectional shape; accordingly, the bottom surface of the groove is the second diffusion portion 2112, and both side surfaces of the groove are the first diffusion portion 2111 and the second diffusion portion 2112, respectively. Of course, the light source cavity 2110 can also be a groove structure with other shapes; for example, a groove structure having an arc-shaped cross-sectional shape (as shown in fig. 7), a groove structure having a U-shaped cross-sectional shape, or the like.
Specifically, the light source cavity 2110 is a groove structure formed by splicing three light diffusion plates, and accordingly, serves as a first diffusion portion 2111, a second diffusion portion 2112, and a third diffusion portion 2113. Meanwhile, as a specific requirement of the light transmittance of the second diffusion portion 2112, the light transmittance of the second diffusion portion 2112 may be 80%, so that the light flux of the second diffusion portion 2112 accounts for 80%, and the light fluxes of the first diffusion portion 2111 and the third diffusion portion 2113 respectively account for 10%, and further, the light flux ratio distribution may ensure that the light fluxes emitted from the first diffusion portion 2111 and the third diffusion portion 2113 are within a reasonable range, so that sufficient light energy is reflected by the reflector to achieve a light distribution shape required by the whole lamp, and at the same time, the light energy reflected and controlled by the first light reflecting element 213 and the second light reflecting element 212 does not account for too much light energy. As specific specification and dimension requirements of the light diffusion plate, the height of the light diffusion plate may be 12mm and the width may be 31 mm.
Of course, the light source cavity 2110 may also be a groove structure formed by splicing two or more light diffusion plates, or a groove structure formed by integrally molding one light diffusion plate; meanwhile, the requirements of the first diffusion portion 2111, the second diffusion portion 2112, and the third diffusion portion 2113 for the light transmittance and the specification and size of the light diffusion plate can be adaptively adjusted according to the specific application scene and the light distribution intensity requirements.
Preferably, the second diffusion portion 2112 may be provided with microstructures 21120 arranged in an array, so that light rays emitted from the light source cavity 2110 to the second diffusion portion 2112 can be refracted at multiple angles by the microstructures 21120, and further, the light emitted directly from the flared end 214 through the second diffusion portion 2112 is more uniform, so that the light distribution curve is more rounded; wherein, the microstructure 21120 may be a protrusion or a groove with a triangular, arc or circular cross section, or a circular or conical protrusion or a pit, etc.; meanwhile, the microstructures 21120 may be provided on the inner side surface of the second diffusion portion 2112 (i.e., the surface located in the light source cavity 2110), or may be provided on the outer side surface of the second diffusion portion 2112 (i.e., the surface located outside the light source cavity 2110) or in the second diffusion portion. Of course, the second diffusion portion 2112 may also be a smooth plane, i.e., the microstructure 21120 is not provided.

Here, the first anti-glare element 2301 and the second anti-glare element 2302 may be both mirror plates or prism plates, etc. which may be used as anti-glare optical elements.
Specifically, as a specific setting requirement of the light-shielding angles of the first anti-glare element 2301, the second anti-glare element 2302, the first light-reflection element 213 and the second light-reflection element 212, the light-shielding angles of the first anti-glare element 2301 and the second anti-glare element 2302 are 46.5 °, and the light-shielding angles of the first light-reflection element 213 and the second light-reflection element 212 are 32 °, so that a more comfortable lighting experience can be provided.
