Detailed Description

In order to make the technical problems, technical schemes and beneficial effects solved by the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

First embodiment

As shown in fig. 1 and fig. 2, a lamp provided by a first embodiment of the present utility model includes a housing 2, a panel 1, and a lamp panel 4; a cavity 22 is arranged in the shell 2, the cavity 22 is provided with a first opening 23, and the panel 1 is connected with the shell 2 and seals the first opening 23; the lamp panel 4 is arranged in the cavity 22, the lamp panel 4 is directly connected with a power supply, and the light of the lamp panel 4 is directly irradiated to the inner surface of the panel 1; the panel 1 is a light-transmitting structure, and advertisements are arranged on the outer surface of the panel 1. In this embodiment, the lamp panel 4 directly connected with the power supply is adopted to illuminate the panel 1 so as to illuminate the lamp, in other embodiments, the lamp panel 4 can illuminate the panel 1 at other angles, unlike the side light entering of the prior art, the embodiment omits the PCB control panel and front light entering, and can also omit reflective paper, so that the lamp has the advantage of simple structure, and in the actual production and assembly, the lamp panel 4 does not need fine processes such as film sticking and paper pasting, and is convenient to install and assemble.

The material of the panel 1 in this embodiment may be a completely transparent material or a translucent material. The light transmittance of the panel in the embodiment is 90% -95% only by meeting the requirement of light transmittance.

As shown in fig. 3, in the present embodiment, the cross section of the panel 1 is larger than the cross section of the first opening 23, and the front projection of the first opening 23 on the panel 1 divides the panel 1 into a projection area 25 and a non-projection area 26. A diffuse reflection structure is provided in the projection area 25, the diffuse reflection structure being provided on the inner surface of the panel 1, the diffuse reflection structure being used to redirect light rays so as to direct part of the light rays incident into the projection area 25 to the non-projection area 26. Specifically, the diffuse reflection structure includes a plurality of protrusions 11 regularly arranged on the inner surface of the panel 1, the plurality of protrusions 11 protruding from the inner surface of the panel 1. Since the protrusion 11 protrudes from the inner surface of the panel 1, light rays are perpendicularly emitted to the protrusion 11, reflected on the surface of the protrusion 11, and refracted on the surface entering the protrusion 11, compared with the inner surface of the panel 1 being planar, the protrusion 11 in this embodiment increases the reflection and refraction of light rays, thereby changing the irradiation route of multiple light rays, so that a part of light rays are emitted from the non-projection area 26, finally reducing the illumination intensity of the projection area 25, reducing the illumination intensity difference between the projection area 25 and the non-projection area 26, that is, the brightness of the projection area 25 and the non-projection area 26 is closer, and the brightness of the panel 1 is more uniform.

As shown in fig. 2, in the present embodiment, the cross section of the projection 11 is gradually reduced from the direction away from the panel 1; specifically, the projections 11 are pyramid-shaped. In this embodiment, the protrusion 11 and the panel 1 are integrally formed, and the panel 1 in this embodiment may be a transparent plastic material such as PMMA, PC, PVC, PP. The pyramid-shaped protrusions 11 have smaller surface gaps and are more likely to reflect.

As shown in fig. 4, in the present embodiment, the light fixture further includes a light diffusion plate 3, the light diffusion plate 3 is disposed between the light panel 4 and the panel 1, and the light diffusion plate 3 and the light panel 4 are disposed at intervals; the panel 1 and the lamp panel 4 are arranged at an included angle. The light-diffusing plate 3 is used to diffuse the light of the lamp panel 4 in advance so that the light does not all enter the panel 1 in a vertical direction.

In this embodiment, a plurality of beads are provided on the surface of the lamp panel, or an annular lamp is mounted on the surface of the lamp panel, and the light emitting area of the lamp panel 4 is equal to or smaller than the projection area 25. The lamp panel 4 is a bi-color lamp panel 4 or a multi-color lamp panel 4, the luminous colors of the lamp panel 4 are matched according to actual needs, but the luminous area of the lamp panel 4 can be smaller than the area of the projection area 25, the area of the luminous surface of other direct-injection panels 1 in the prior art is required to be larger than or equal to the area of the projection area 25, otherwise, the light emitted outwards by the panels 1 is not uniform, the propaganda effect is influenced, and the area of the projection area 25 is not required to be larger than the area of the projection area 25.

As shown in fig. 1 and 4, in the present embodiment, the housing 2 is provided with a groove 21, the groove 21 communicates with a cavity 22, and the panel 1 is embedded in the groove 21. Specifically, the outer contour of the panel 1 in this embodiment is regular hexagon, while the projection area 25 is circular, the cavity 22 is circular, and the cross section of the groove 21 is hexagonal. The panel 1 in this embodiment may be provided in the recess 21 by means of adhesive, bolting, welding or the like.

In other embodiments, the profile of the panel 1 is circular, the recess 21 is circular, and the cross section of the cavity 22 is hexagonal, the panel 1 still being embedded in the recess 21.

As shown in fig. 1, in the present embodiment, the cavity 22 further has a second opening 24, the second opening 24 and the first opening 23 are disposed opposite to each other, and a cover plate 5 is disposed at the second opening 24, and the cover plate 5 is detachably connected to the housing 2 to close the second opening 24. The removable connection of the cover plate 5 is in this embodiment a screw connection, but in other embodiments it may be by means of a snap, screw, etc., in other embodiments the cavity 22 may have only the first opening 23, i.e. the cavity 22 is blind.

In this embodiment, the light-diffusing plate 3 has flexibility, and is preferably a silica gel light-diffusing plate 3, wherein the thickness of the light-diffusing plate 3 is 1-15mm, and the light transmittance thereof is 20% -30%.

Second embodiment

The luminaire of the second embodiment of the utility model differs from the first embodiment in that the orthographic projection of each cross section of the protrusion on the surface of the panel coincides in the direction away from the panel, i.e. the cross section of each place of the protrusion in the present embodiment remains unchanged in the direction away from the panel. For example, the projections in the present embodiment are prisms having a polygonal cross section, not the pyramids having a gradually smaller cross section in the first embodiment.

Third embodiment

The lamp of the third embodiment of the present utility model is different from the lamp of the first embodiment in that the protrusions may be arc-shaped, and the plurality of protrusions may be arranged in a fish scale shape or in a ring-shaped water wave shape after being arranged.
