Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to the drawings, an embodiment of the present application provides a frameless panel lamp including a back plate 10, a diffusion plate 30, and a light emitting assembly 20.

In some embodiments, the light emitting assembly 20 is a plurality of LED light bars arranged in parallel, as shown in fig. 6, each LED light bar includes a substrate 21 and LED light beads 22 disposed on the substrate 21, if necessary, a lens 23 covering the LED light beads 22 may be disposed on the substrate 21 to increase the light emitting angle thereof, and in a case that the number of the light beads is limited, the light emission of the panel light is as uniform as possible. The adjacent LED light bars are connected through wires or flexible substrates, generally through welding.

The back plate 10 has a housing-like structure, and may be formed by pressing a metal plate or by injection molding. As shown in fig. 3 and 7, the back plate 10 is provided with a mounting area 11, a transition area 13 and a decorative area 12 in sequence from the center to the edge; the mounting region 11 and the trim region 12 are generally parallel to the diffuser plate 30 and are at two different heights, with the transition region 13 extending between the mounting region 11 and the trim region 12.

The mounting region 11 is mainly used for fixedly mounting the light emitting element 20, as shown in fig. 4 and 5, light emitted from the light emitting element 20 can pass through the diffusion plate 30, and the diffusion plate 30 has a light-equalizing function, so that light can be emitted uniformly. The transition section 13 forms a cavity with the mounting section 11 and is provided with a slot 14 for securing a diffuser plate 30. A diffuser plate 30 is mounted within the cavity and is inserted into the slot 14 to keep the light emitting elements 20 in a relatively enclosed space.

In order to improve the heat dissipation effect, in some embodiments, as shown in fig. 6, criss-cross grooves 111 are formed in the mounting region 11, the led light bars are fixed in the grooves 111 in one direction by an adhesive, and the wires or the flexible substrate are mounted in the grooves 111 in the other direction. To enhance the luminous effect, in some embodiments, the inner side of the back sheet 10 is provided with a reflective layer, which may be a reflective paper or a reflective coating.

To secure the diffuser 30, as shown in fig. 3, the card slot 14 has an upper surface 141 and a lower surface 142 that are oppositely disposed, and has a clamping portion 143 that clamps the diffuser 30 with a reduced distance between the upper and lower surfaces. The holding portion 143 is formed after the diffuser plate 30 is mounted in place, and may be formed at the time of manufacturing the back plate 10. By clamping the fixed diffuser plate 30 by the clamping portion 143, the rest of the area of the back plate 10 can be prevented from abutting against the fixed diffuser plate 30, preventing the edge of the diffuser plate 30 from having dark areas.

In some embodiments, as shown in fig. 5, the transition region 13 includes a guiding portion 131, a fixing portion 132, and an extending portion 133, which are sequentially disposed. The fixing portion 132 is provided with the card slot 14, the guiding portion 131 is used for guiding the diffusion plate 30 to enter the card slot 14, and the extending portion 133 is used for reflecting light, so that the panel light has a larger light emitting area. In order to avoid the occurrence of dark areas in the diffuser 30, in some embodiments, the fixing portion 132 is vertically disposed, i.e., perpendicular to the diffuser 30, and the guiding portion 131 and the extending portion 133 are disposed obliquely to the vertical direction, which can be seen that this structure makes the light incident surface and the light emitting surface of the diffuser 30 the same, so that the light emitting illuminance can be the same everywhere.

In order to make it easier for the diffusion plate 30 to enter the card slot 14, as shown in fig. 3, the guiding portion 131 has a larger inclination angle, preferably a larger inclination angle than the extending portion 133. Theoretically, the larger the distance between the diffusion plate 30 and the light emitting module 20 is, the larger the light emitting area of the panel lamp is, and therefore, in the limited space of the panel lamp, the height of the extension 133 should be increased as much as possible, and preferably, the height of the extension 133 is more than 80% of the total height of the panel lamp.

Since the holder 143 is press-fit with the diffuser 30, in some embodiments, as shown in fig. 5, the holder 143 has a certain elasticity to prevent the diffuser 30 from loosening. The upper and lower surfaces are preferably provided in the clamping portion 143 as arc-shaped structures, which allow surface contact between the upper and lower surfaces and the diffusion plate 20, thereby improving the reliability of fixation. For convenience of installation, the card slot 14 is provided with an installation margin 144 at the outer side of the clamping portion 143.

To prevent the diffuser plate 30 from falling off, as shown in fig. 7, the card slot 14 is preferably in a ring-shaped structure, i.e., disposed around the housing 10. However, the clamping portion 143 may be arranged discontinuously, and it may be arranged in a plurality of positions and at intervals to reduce the difficulty of manufacturing.

In order to improve the strength of the decoration region 12, as shown in fig. 3, the edge of the decoration region 12 is provided with a flange 121, and the flange 121 may have a multi-fold structure, wherein the first fold is perpendicular to the horizontal plane, and the second fold is parallel to the horizontal plane, so as to effectively prevent the decoration region 12 from deforming, and in addition, effectively prevent the edge of the back plate 10 from cutting the user. If necessary, the outward turned edge 121 can be provided with a hanging hole or a hanging piece.

To light the panel light, the light emitting assembly 20 needs to be electrically connected to an external power source, so that the back plate 10 is provided with a threading hole 15, and the threading hole 15 is used for a power supply line to pass through.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features. When technical features in different embodiments are represented in the same drawing, it can be seen that the drawing also discloses a combination of the embodiments concerned.

The above-mentioned embodiments only express several implementation modes of the present application, and the description thereof is specific and detailed, but not construed as limiting the scope of the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
