Description

Technical Field

[0001] The utility model relates to the field of lighting devices, in particular to a nearly flat mounting chassis and a panel lamp using the mounting chassis. Background Art

[0002] LED panel lights are a main lighting fixture used in commercial office spaces. One of the mainstream structural methods of existing LED panel lights is to adopt direct-down lighting, that is, the internal LED light bar is installed on the chassis of the lamp, and the light-emitting direction of the LED light bar is consistent with the normal direction of the light-emitting surface of the panel light. In this structure, due to the large light-emitting angle of the LED lamp beads, in order to ensure the uniformity of the light-emitting surface, it is often necessary to place the LED light bar away from the light-emitting surface of the panel light, that is, the distance between the LED light bar and the light-emitting surface is far. The current main practice is to process the chassis of the lamp to make a deeper recessed space for placing the LED light bar, which will cause the thickness of the direct-down panel light to increase. For example, patent 202321034467.9 uses a direct-down panel light with a back cover (i.e., chassis) structure with a deeper recessed space. Utility Model Content

[0016] In order to make the purpose, technical solution and advantages of the present application clearer, the present application is described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0017] It should be understood that the terms "upward", "downward", "upper" and "lower" are only used to indicate relative relationships, rather than to indicate or imply a specific direction that the device referred to must have, and therefore should not be understood as limiting the present application.

[0018] It should be noted that the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" and "several" is two or more, unless otherwise clearly and specifically defined.

[0019] Combination Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the utility model discloses a nearly planar mounting chassis, which is composed of a chassis body 1. The chassis body 1 is a planar metal plate, which is usually an aluminum alloy plate and has a rounded rectangular shape. In the middle area of ​​the chassis body 1, a plurality of light bar mounting parts 11 are arranged by a stamping process. The light bar mounting part 11 is a first groove protruding toward a first direction. The groove body of the first groove is in the shape of a rectangular slender strip. The plurality of light bar mounting parts 11 are arranged in parallel and at intervals, and the spacing between adjacent parts is equal. The groove body size specifications of each light bar mounting part 11 are consistent to facilitate fixing the same LED light bar. The LED light bar is fixed to the bottom of the groove body of the light bar mounting part 11 by gluing. The groove body depth of the light bar mounting part 11 is about 3mm~6mm, and the groove width is about 8mm~16mm. Therefore, the setting of the light bar mounting part 11 basically does not affect the overall plane effect of the chassis body 1. In some other embodiments, the groove sizes and widths of the plurality of light bar mounting portions 11 may also be made inconsistent, so as to accommodate fixing a plurality of LED light bars of different specifications in one chassis body.

[0020] The chassis body 1 is provided with reinforcing ribs 12, which are located at the outer periphery of the light bar mounting portion 11. The reinforcing ribs 12 are connected end to end to form a closed ring shape and surround all the light bar mounting portions 11. The arrangement shape of the reinforcing ribs 12 is parallel to the edge shape of the chassis body 1, that is, arranged along the contour shape of the edge. In this embodiment, the reinforcing ribs 12 are formed by a stamping process to form a second groove protruding toward the second direction, such as Figure 2As shown, the notch section of the second groove is U-shaped, the groove depth of the second groove is about 2mm~3mm, the notch width is about 4mm~8mm, and the first direction of the protrusion of the first groove and the second direction of the protrusion of the second groove are just in the opposite directions of upward and downward. The purpose of setting the opposite directions is to improve the plane strength of the chassis body 1. In some other embodiments, the reinforcing ribs 12 can be formed by adding material processing, such as adding strip-shaped metal materials to the chassis body 1 by hot welding, and the strip-shaped metal materials form protrusions on the chassis body, which can also serve as the effect of strengthening the structure; in some other embodiments, the reinforcing ribs 12 adopt a non-closed surrounding method to surround all the light bar mounting parts 11, such as a segmented surrounding shape.

[0021] like Figure 3 As shown, Figure 3 This is a cross-sectional view avoiding the light bar installation portion. It can be seen that the flatness of the chassis body 1 can be effectively maintained.

[0022] Combination Figure 4 As shown, the embodiment of the utility model also discloses a panel light, including a chassis body 1, a profile frame 2, a light-transmitting plate 3, an LED light bar 4 and a power supply 5. The light-transmitting plate 3 is clamped in the annular groove on the lower surface of the profile frame 2 and is basically flush with the lower surface of the profile frame. The light-transmitting plate 3 is usually composed of a PMMA acrylic plate and a diffusion film attached to the acrylic plate. The chassis body 1 is provided with a plurality of screw holes around the edge side, and the chassis body 1 is fixed to the upper surface of the profile frame 2 by screw locking. The LED light bar 4 is adhesively fixed to the light bar mounting portion 11 of the chassis body 1. The power supply 5 is fixed in the power supply receiving groove provided on the chassis body 1. The power supply 5 forms an electrical connection with the LED light bar 4 to supply power to the LEDs in the LED light bar to emit light. In addition, the panel light can also add some additional mounting components to facilitate installation.

[0023] The above-mentioned embodiments only express the implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
