All other embodiments obtained by a person skilled in the art based on the present embodiment without any creative effort belong to the protection scope of the present embodiment.
The composite reflection lamp cover of the present embodiment will be described with reference to fig. 1 to 5. The composite reflection lampshade 1 of the embodiment is suitable for decorative lighting lamps such as wall washing lamps and embedded spot lamps.
Referring to fig. 1, the present embodiment provides a composite reflective lamp cover 1, which is adapted to surround the light source, and includes a lens 10 and a reflective cup 20.
Specifically, the bottom of the lens 10 is open and surrounds a light emitting area 100 for enclosing a light source, light emitted by the light source passes through the lens 10 in a direction away from the opening of the lens 10, and the light emitted by the light source is refracted by the lens 10 with different beam angles to form different arc widths corresponding to the beam angles. The reflecting cup 20 is arranged around the outer circumference of the lens 10, the inner diameter of the reflecting cup 20 increases gradually along the direction of increasing the height of the reflecting cup 20, the bottom part with the smallest inner diameter of the reflecting cup 20 is arranged to penetrate through the top part with the largest inner diameter, and the edge of the bottom part of the reflecting cup 20 is fixedly connected with the edge of the bottom opening of the lens 10 in a sealing way.
In some embodiments, the reflector cup 20 is a hollow cylindrical cup, and the lens 10 is a bowl with a downward opening and is inverted at the bottom of the reflector cup 20; the lens 10 may be fixed to the bottom of the reflecting cup 20 by means of an integral molding, so as to form a complete optical element together with the reflecting cup 20.
Referring to fig. 1 and 2, a plurality of sets of reflective protrusions are distributed on an inner surface of the reflective cup 20, and surfaces of the reflective protrusions are disposed in a curved shape to reflect light emitted from the light source and refracted by the lens 10, so that different light arc widths corresponding to light beam angles are respectively formed between the light beams passing through the lens 10 having different light beam angles.
In practical application, through integrated into one piece's reflection cup 20 and lens 10 to set up multiunit reflection arch in reflection cup 20, make the light that the light source sent be reflected after meetting the reflection arch, greatly alleviateed reflection cup 20 to the diffuse effect of light, make the light arc width of the light after being reflected correspond with the original beam angle of lens 10, and can not receive the influence of reflection cup 20 opening size. The defects that the actual light arc width of the wall washing lamp in the prior art does not correspond to the light beam angle and the lighting effect and the user experience are affected are overcome, the light arc width corresponds to the light beam angle, and the lighting effect and the user experience of the wall washing lamp are improved.
Referring to fig. 1 to 4, in order to sufficiently reflect the light refracted through the lens 10, the shape of the reflective protrusion, the height position in the reflective cup 20, corresponds to the beam angle of the lens 10.
Referring to fig. 1 and 2, in some specific embodiments, for a lens 10 having a large beam angle (e.g., 120 degrees obtuse angle), the reflective protrusions are scale-like protrusions 200 that abut each other and are closely spaced on the inner surface of the reflective cup 20. The scale-shaped protrusions 200 are in multiple groups, the multiple groups of scale-shaped protrusions 200 are distributed along the height direction of the reflecting cup 20, the projection areas of any group of scale-shaped protrusions 200 on the plane where the reflecting cup 20 is located in the height direction are all equal, and any group of scale-shaped protrusions 200 are arranged in the space between the plane where the reflecting cup 20 is located at the bottom and the plane where the top of the lens 10 is located. In the present embodiment, each scale-like protrusion 200 occupies an equal area on the reflective cup 20.
With this arrangement, the light refracted by the lens 10 with a larger beam angle from the light source has a propagation path closer to the bottom of the reflector cup 20, so that a plurality of sets of closely-arranged scale-shaped protrusions 200 are arranged near the bottom of the reflector cup 20, thereby achieving a better reflection effect.
Referring to fig. 3 and 4, in some specific embodiments, for a lens 10 with a small beam angle (e.g., a 70 degree acute angle), the reflective protrusions are strip-shaped protrusions 210 that are wound around the inner surface of the reflective cup 20, and the plane of the strip-shaped protrusions 210 is flush with the plane of the top of the reflective cup 20. The plurality of sets of the strip-shaped protrusions 210 are distributed along the height direction of the reflective cup 20, the projection areas of any strip-shaped protrusion 210 on the plane where the height direction of the reflective cup 20 is located are all equal, and any strip-shaped protrusion 210 is arranged in the space between the top of the reflective cup 20 and the plane where the top of the lens 10 is located in the reflective cup 20. In the present embodiment, the area occupied by each of the strip-shaped protrusions 210 on the reflective cup 20 is equal, and the length of each of the strip-shaped protrusions 210 is equal.
With this arrangement, the light rays refracted by the lens 10 with a smaller beam angle from the light source have a propagation path closer to the top opening of the reflective cup 20, so that a plurality of sets of the strip-shaped protrusions 210 are disposed at a position close to the top of the reflective cup 20, thereby achieving a better reflection effect.
It can be easily found that, for the compound reflector lamp cover 1 of the present embodiment, the light arc width corresponds to the size of the beam angle of the lens 10: the larger the beam angle, the larger the arc width; the smaller the beam angle, the smaller the arc width.
Referring to fig. 2 and 4, the thickness of each of the reflective protrusions is 1 mm to 2 mm, and the radius of curvature of each of the reflective protrusions is 10 mm to 50 mm. With such an arrangement, the reflecting bulge is provided with the reflecting 'microstructure' with small thickness and small curvature radius, no matter the scaly bulge 200 or the strip-shaped bulge 210, not only can a good reflecting effect be formed on light, but also the occupied area and space in the reflecting cup 20 are small, and the manufacturing cost of the lampshade is reduced.
Referring to fig. 5, the composite reflection lampshade 1 of the present embodiment further includes a light shield 30, the light shield 30 is coaxially connected to a side of the reflection cup 20 other than the top thereof, and the light shield 30 is communicated with the reflection cup 20. In this embodiment, the light shield 30 is provided with a reference, so that the width of the light arc can be defined more intuitively and clearly. Specifically, an included angle between two reflected light beams that are cut off by the opening edge of the light shield 30 and located on the same plane is an arc angle, a distance from an intersection point of the two reflected light beams to the opening edge of the light shield 30 is an arc radius, and an arc width is a product of the arc angle and the arc radius.
In summary, by adopting the above technical solution, a plurality of groups of reflective protrusions are disposed in the reflective cup 20, and the scale-shaped protrusions 200 or the strip-shaped protrusions 210 are respectively disposed according to the size of the beam angle of the lens 10, so that the light emitted from the light source is refracted by the lens 10 and then reflected after encountering the reflective protrusions, thereby greatly reducing the diffusion effect of the reflective cup 20 on the light, and making the light arc width of the reflected light correspond to the original beam angle of the lens 10 without being affected by the size of the opening of the reflective cup 20. The defects that the actual light arc width of the wall washing lamp in the prior art does not correspond to the light beam angle and the lighting effect and the user experience are affected are overcome, the light arc width corresponds to the light beam angle, and the lighting effect and the user experience of the wall washing lamp are improved.
Referring to fig. 6, the present embodiment further provides an illumination fixture, which includes a light source, a lamp holder 2 and the composite reflective lampshade 1.
Specifically, the complex reflection lamp cover 1 is installed at the lamp socket 2, the light source is located at the light emitting area 100, and the light emitted from the light source passes through the lens 10 having different beam angles and is reflected by the reflection protrusions, thereby forming different arc widths corresponding to the beam angles, respectively. The lighting fixture of the present embodiment has all the advantages of the composite reflective lampshade 1, and will not be described herein again.
Finally, it should be noted that: the above embodiments are merely illustrative of the technical solutions and are not limiting; although described in detail with reference to the foregoing embodiments, those of ordinary skill in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
