Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a panel lamp. Background Art

[0002] Panel lights are widely used in shopping malls, large supermarkets, office spaces, museums, exhibition halls, hotels, high-end residences and other places, and are important lighting products.

[0003] For example, a Chinese utility model patent with authorization announcement number CN218721079U discloses "A small panel lamp", which includes a lamp housing with a downward opening cavity, a light-emitting component arranged in the lamp housing, a light-guiding component arranged in the lamp housing, and a diffusion plate corresponding to the opening and covering the bottom of the light-guiding component. The edge of the lamp housing is provided with a flange circumferentially outwardly, and an annular cover plate is fixedly provided below the flange to match the flange. The inner edge of the cover plate extends upward as a whole with a support plate that is supported on the light-guiding component, and the diffusion plate is limited on the support plate.

[0004] The above panel lights use a diffusion plate, and the transparent area of ​​the diffusion plate is small, which needs further improvement. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a panel lamp capable of increasing the light transmission area in view of the current status of the prior art.

[0006] The utility model adopts the following technical solution to solve the above technical problems: a panel light, comprising

[0007] The shell comprises a cylindrical vertical extension portion, and a transverse extension portion connected to the lower edge of the vertical extension portion and extending outward, wherein the transverse extension portion is annular;

[0008] A first light-transmitting housing is disposed in the space enclosed by the vertically extending portion;

[0009] A light emitting element, arranged on the housing;

[0010] Features:

[0011] The shell is made of light-transmitting material at least in the vertical extension portion;

[0012] The second light-transmitting shell is arranged outside the vertically extending portion of the shell body, and forms a mounting cavity with the vertically extending portion and the horizontally extending portion.

[0013] In order to facilitate the disassembly and assembly of the second light-transmitting shell, the second light-transmitting shell is detachably connected to the vertically extending portion of the housing.

[0014] The detachable structure of the second light-transmitting housing is specifically that the second light-transmitting housing is connected to the vertical extension portion of the housing by a buckle, and other methods such as magnetic attraction, threaded connection, etc. can also be used to achieve detachable connection.

[0015] The buckle structure is specifically that one of the second light-transmitting shell and the vertically extending portion of the shell has a clamping groove, and the other has a limiting rib extending into the clamping groove.

[0016] In order to make the shell meet the installation requirements of the first light-transmitting shell and the second light-transmitting shell at the same time, the first light-transmitting shell is directly clamped with the inner peripheral wall of the vertical extension portion of the shell, and the clamping position is consistent with the clamping position of the second light-transmitting shell and the vertical extension portion of the shell, and the clamping structure is adapted to the shape of the inner peripheral wall of the vertical extension portion of the shell;

[0017] Alternatively, an annular connecting piece is provided between the first light-transmitting shell and the inner circumferential wall of the vertical extension portion of the shell, one end of the connecting piece supports the first light-transmitting shell upward, and the other end is clamped with the vertical extension portion, and the clamping position is consistent with the clamping position of the second light-transmitting shell and the vertical extension portion of the shell, and the clamping structure is adapted to the shape of the inner circumferential wall of the vertical extension portion of the shell.

[0018] In this way, the structure of the vertical extension portion of the shell body satisfies the requirements of being clamped and installed with the first light-transmitting shell and the second light-transmitting shell, which is helpful to simplify the manufacturing process of the panel light.

[0019] The structure of the second light-transmitting housing is specifically as follows:

[0020] The outer cover, together with the vertical extension part and the horizontal extension part of the shell, forms the installation cavity;

[0021] A mounting foot extending downwardly from an inner wall of the outer cover adjacent to a vertically extending portion of the shell;

[0022] The buckle is located between the mounting foot and the vertical extension.

[0023] Preferably, the light emitting element is installed in the installation cavity. The light emitting element may also be installed in a space enclosed by the housing and the first light-transmitting outer shell, for example, the light emitting element is connected to the inner peripheral wall of the vertically extending portion of the housing.

[0024] The structure of the light-emitting element is specifically that the light-emitting element is a light bar arranged around the outer periphery of the vertically extending portion of the shell;

[0025] The light strip is trapped between the mounting foot and the vertical extension.

[0026] In this way, the mounting foot has two functions at the same time, one is to connect the second light-transmitting shell to the shell, and the other is to limit the position of the light strip, which is conducive to the stability of the light strip. The light-emitting element can also adopt other structures, such as having multiple lamp beads, different lamp beads are distributed at intervals and are independent of each other, and the light-emitting element can also be set in other positions, such as in the space surrounded by the vertical extension of the shell.

[0027] The structure of the housing is specifically that the housing also includes

[0028] A flange extending upward from the outer edge of the transversely extending portion and in a ring shape;

[0029] The outer cover includes

[0030] An upper extension plate, located above the transverse extension portion of the shell and outside the vertical extension portion;

[0031] The outer extension plate extends downward from the outer edge of the upper extension plate and has a step portion resting on the flange.

[0032] In this way, the positioning and installation between the housing and the outer cover are facilitated by providing the flange and the step portion.

[0033] In order to install the power cord, the housing includes

[0034] A mounting plate is located in the space enclosed by the vertical extension portion and connected to the upper edge of the vertical extension portion, and the mounting plate is located above the first light-transmitting housing;

[0035] The vertical extension portion has a threading hole that runs through the wall thickness transversely and is located higher than the light-emitting member, and the threading hole is located in the installation cavity;

[0036] The mounting plate is used to install a power line, which passes through the mounting plate and the threading hole in sequence and then is electrically connected to the light-emitting element;

[0037] The shell is integrally formed.

[0038] In this way, it is easy to install the power cord, and the power cord is hidden inside the panel light, which complies with the specification and has a simple appearance. The one-piece molding reduces the assembly process of the shell.

[0039] Compared with the prior art, the advantages of the present invention are that the shell is made of a light-transmitting material at least in the vertical extension portion and a second light-transmitting shell is provided. When the light-emitting element is working, part of the light is transmitted through the first light-transmitting shell, and the other part of the light is transmitted through the second transparent shell. In this way, the light-transmitting area of ​​the entire panel lamp is larger, thereby improving the lighting effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The housing 3 is integrally formed, and preferably uses a material that facilitates heat dissipation of the light-emitting element 4. Figure 4As can be seen, the housing 1 includes a cylindrical vertical extension portion 31, a transverse extension portion 32 connected to the lower edge of the vertical extension portion 31 and extending outward, a flange 33, and a mounting plate 34; the transverse extension portion 32 is annular; the housing 3 is made of a light-transmitting material in the vertical extension portion 31, and preferably, the entire housing 3 is made of a light-transmitting material; the flange 33 extends upward from the outer edge of the transverse extension portion 32 and is annular; the mounting plate 34 is located in the space surrounded by the vertical extension portion 31 and is connected to the upper edge of the vertical extension portion 31, and the mounting plate 34 is located above the first light-transmitting housing 1. The vertical extension portion 31 has a threading hole 311 that runs through its wall thickness horizontally and is located higher than the light-emitting element 4, and the threading hole 311 is located in the mounting cavity; the mounting plate 34 is used to install a power cord, and the power cord (only part of the power cord is shown in the figure) passes through the mounting plate 34 and the threading hole 311 in sequence and is electrically connected to the light-emitting element 4. Specifically, the second light-transmitting housing 2 has a covering portion 2 b that protrudes upward and covers the threading hole 311 , and a gasket 400 is disposed outside the covering portion 2 b.

[0054] The first light-transmitting housing 1 is disposed in the space enclosed by the vertical extension portion 31. The first light-transmitting housing 1 is preferably made of environmentally friendly high-transmittance plastic material to facilitate light diffusion. The first light-transmitting housing 1 is directly snap-fitted with the inner peripheral wall of the vertical extension portion 31 of the housing 3, and the snap-fitting position is consistent with the snap-fitting position of the second light-transmitting housing 2 with the vertical extension portion 31 of the housing 3, and the snap-fitting structure is adapted to the shape of the inner peripheral wall of the vertical extension portion 31 of the housing 3.

[0055] The light emitting element 4 is arranged on the housing 3, specifically connected to the outer peripheral wall of the vertical extension portion 31 of the housing 3, and is located in the installation cavity surrounded by the second light-transmissive shell 2 and the housing 3. The light emitting element 4 is a light bar arranged around the outer periphery of the vertical extension portion 31 of the housing 3.

[0056] The second light-transmitting shell 2 is arranged outside the vertical extension portion 31 of the shell 3, and together with the vertical extension portion 31 and the lateral extension portion 32, forms a mounting cavity for installing the light-emitting component 4. The second light-transmitting shell 2 is detachably connected to the vertical extension portion 31 of the shell 3. Preferably, the second light-transmitting shell 2 is connected to the vertical extension portion 31 of the shell 3 by a snap. In the second light-transmitting shell 2 and the vertical extension portion 31 of the shell 3, the second light-transmitting shell 2 has a card slot 2a, and the shell 3 has a limiting rib 31a extending into the card slot 2a, and the positions of the limiting rib 31a and the card slot 2a can also be interchanged. The second light-transmitting shell 2 includes an outer cover 21 and a mounting foot 22. The outer cover 21 and the vertical extension portion 31 and the lateral extension portion 32 of the shell 3 form a mounting cavity. The outer cover 21 is in an inverted L shape, and includes an upper extension plate 211 and an outer extension plate 212. The upper extension plate 211 is located above the lateral extension portion 32 of the housing 3 and outside the vertical extension portion 31.

The reflective paper 100 is made of environmentally friendly PET material, which reduces light loss by reflecting light to the light guide plate 200. The light guide plate 200 is made of a material with high light transmittance, such as PMMA material, which is conducive to the softer and more uniform light emitted by the panel light. When the panel light is installed, the gasket 400 can fill the space between the panel light and the installation surface to avoid the influence of different flatness of the installation surface on the installation.

[0058] Here's how it works.

[0059] The light emitting element 4 is powered by the power cord 10. When the light emitting element 4 is working, part of the light is transmitted through the first light-transmitting shell 1, and the other part of the light is transmitted through the second transparent shell 2. In this way, the light-transmitting area of ​​the entire panel light is larger.
