The invention relates to the technical field of lighting equipment, in particular to a reflecting assembly and a lamp.

Background

The existing lamps have various types, including household common lighting lamps, industrial projection lamps, industrial mining lamps and the like. The traditional lamp comprises a light source and a reflecting cup, wherein the reflecting cup is sleeved outside the light source, and a certain angle, namely a shading angle, is formed between the side wall of the reflecting cup and the horizontal plane where the light source is located, so that glare generated by the lamp is weakened. However, when the conventional lamp emits light, peripheral glare is obvious and the utilization rate of the light source is low, which causes energy waste.

In one embodiment, the intervals between two adjacent reflector cups are increased from inside to outside.

In one embodiment, starting from the second reflector cup in the radially outward direction, the greater the distance from the rim of one reflector cup to the plane of the lamp panel on which the light source is located, the greater the spacing between the reflector cup and the adjacent previous reflector cup.

In one embodiment, each of the reflector cups has an inner surface and an outer surface, the inner surface of the outermost reflector cup is a reflective surface, and the inner and outer surfaces of the remaining reflector cups are reflective surfaces.

In one embodiment, the reflector assembly further comprises a transparent cover plate, the transparent cover plate is arranged on one side of the bottoms of the plurality of reflector cups and is an annular plate, the inner ring of the transparent cover plate is connected with the outer cup wall of the innermost reflector cup, the outer ring of the transparent cover plate is connected with the inner cup wall of the outermost reflector cup, and the rest reflector cups are sequentially arranged on the transparent cover plate at intervals.

The invention also discloses a lamp which comprises a light source and any one of the light reflecting components.

In one embodiment, the light source is an LED lamp, and the LED lamp is positioned on the central axis of the innermost layer of the reflecting cup.

In one embodiment, the light source comprises an LED lamp panel and annular LED lamp groups, wherein the LED lamp panel is provided with a plurality of annular LED lamp groups which are concentrically distributed; at least one annular LED lamp group is correspondingly distributed between every two adjacent reflecting cups.

Referring to fig. 1, 2 and 3, a reflector assembly 100 according to an embodiment of the present invention includes a plurality of reflector cups 110, the plurality of reflector cups 110 are sequentially sleeved together, the plurality of reflector cups 110 are concentrically disposed, and two adjacent reflector cups 110 have a gap. Each of the light reflecting cups 110 has a rim and a bottom, and the bottoms of all the light reflecting cups 110 are close to the lamp panel for assembling the light source 200 with respect to the rim thereof. The curvature of the contour curve of the cup wall of each reflector cup 110 cut along the central axis is gradually increased from the cup bottom to the cup mouth, and the curvature center of each reflector cup 110 is positioned at the outer side of the reflector cup 110. The distances from the cup mouths of the plurality of light reflecting cups 110 to the plane of the lamp panel on which the light source 200 is positioned increase from inside to outside in sequence.

The structural form of the reflective cup 110 may be various, for example: the cross section of the reflective cup 110 may be rectangular, square, oval, or circular, etc. The material of the reflective cup 110 may be various, for example: plastic, aluminum alloy, copper, and the like.

In the plurality of reflector cups 110, the interval between two adjacent reflector cups 110 may be the same or different. In one embodiment, the interval between two adjacent reflector cups 110 increases from inside to outside. By properly increasing the distance between two adjacent reflecting cups 110, the number of the reflecting cups 110 is reduced as much as possible while the lighting effect is ensured, and the consumption of the reflecting cups 110 in the manufacturing process of the lamp is reduced, so that the use of raw materials is saved. Preferably, in a radially outward direction and starting from the second reflector cup 110, the greater the distance from the rim of one reflector cup 110 to the plane of the lamp panel on which the light source 200 is located, the greater the distance between the reflector cup 110 and the adjacent previous reflector cup 110, so as to further facilitate adjustment of the light-emitting angle of the light which is easy to generate glare. Of course, the curvature, height, and distance between two adjacent reflectors 110 of the plurality of reflectors 110 may be selected according to practical situations.

As an implementation manner, the light reflecting assembly 100 further includes a transparent cover plate 120, the transparent cover plate 120 is disposed on one side of the bottom of the plurality of light reflecting cups 110, the transparent cover plate 120 is an annular plate, an inner ring of the transparent cover plate 120 is connected to an outer wall of the innermost light reflecting cup 110, an outer ring of the transparent cover plate 120 is connected to an inner wall of the outermost light reflecting cup 110, and the rest of the light reflecting cups 110 are sequentially disposed on the transparent cover plate 120 at intervals. The transparent cover 120 may not only connect the plurality of light reflecting cups 110 together, but also protect the light source 200. The transparent cover 120 may be made of various materials, such as: PC board, glass board, etc.

The light reflecting assembly 100 provided by the embodiment of the invention comprises a plurality of light reflecting cups 110 which are sequentially sleeved together, the curvature of each light reflecting cup 110 is gradually increased from the cup bottom to the cup opening, and the distances from the cup openings of the plurality of light reflecting cups 110 to the plane of the lamp panel on which the light source 200 is positioned are sequentially increased from inside to outside. When the light emitted from the light source 200 passes through the light reflecting assembly, the curvature of the light reflecting cup 110 gradually increases from the bottom to the rim of the cup, so that the light emitting angle is adjusted to enable the light to be uniformly distributed. Meanwhile, some of the light rays reflected from the inner-layer reflector cup 110 have a small included angle with the plane of the light source 200, and glare is very easily formed, and because the outer-layer reflector cup is higher than the inner-layer reflector cup, the light rays are further reflected by the outer-layer reflector cup 110 to adjust the light-emitting angle. The light-emitting angle is adjusted by the plurality of light-reflecting cups 110, so that the glare at the periphery of the lamp is greatly reduced, the utilization rate of light is improved, and the energy waste is reduced.

In addition to the above embodiments, the curvature of the contour curve of the cup walls of the plurality of light reflecting cups 110, which is cut along the central axis, at the same horizontal level with respect to the same horizontal plane gradually decreases from the inside to the outside. Therefore, the emitting angles of the light rays tend to be uniform, so that the light rays are uniformly distributed, and the occurrence of glare is reduced as much as possible.

On the basis of the above embodiments, each of the reflector cups 110 has an inner surface and an outer surface, the inner surface of the outermost reflector cup 110 is a reflective surface, and the inner surfaces and the outer surfaces of the remaining reflector cups 110 are reflective surfaces. In this embodiment, except for the outermost reflective cup 110, the inner and outer surfaces of the other reflective cups 110 are designed as reflective surfaces, which can further increase the utilization rate of light and save more energy.

On the other hand, the embodiment of the invention also discloses a lamp, which comprises a light source 200 and the light reflecting assembly 100 of any one of the above embodiments.

The LED lamp panel is provided with a plurality of annular LED lamp groups which are concentrically distributed; at least one annular LED lamp set is correspondingly distributed between every two adjacent reflecting cups 110. The number of the LED lamp beads in the annular LED lamp group is increased from inside to outside in sequence. Of course, the number of the LED lamp beads of the plurality of annular LED lamp groups may be gradually increased, or may be increased in a stepwise manner, for example, the number of the LED lamp beads of every two, three, or four annular LED lamp groups is gradually increased. In addition, the annular LED lamp groups correspondingly distributed between two adjacent light reflecting cups 110 at the outer layer may be more than the annular LED lamp groups correspondingly distributed between two adjacent light reflecting cups 110 at the inner layer.

In this embodiment, the light source 200 includes an LED lamp panel and a plurality of annular LED lamp groups disposed thereon, the plurality of reflective cups 110 divide the LED lamp panel into a plurality of annular light-emitting areas, and each annular light-emitting area may be disposed with at least one annular LED lamp group. The light-emitting angles of the light sources 200 can be adjusted by the plurality of light-reflecting cups 110, so that the light-emitting angles are uniform and the light distribution is more uniform. And the outer reflector 110 can adjust the light that the inner reflector 110 cannot adjust. Simultaneously, adjust the power of light through the distribution of the number of LED lamp pearl on the design LED lamp plate to make light distribution and luminance more even. The lamp of the embodiment can reduce peripheral glare of the lamp, improve the utilization efficiency of light and effectively save energy.
