Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of file cabinet, more particularly to a file cabinet lighting device. BACKGROUND

[0002] A file cabinet is a kind of furniture for storing files, archives and other data, which is widely used in various office places, libraries, archives rooms and the like. It usually has a cabinet body and a multi-layered shelf structure to realize the classified storage and arrangement of a large amount of data. With the increasing requirements for the refinement and convenience of archive management, the application of lighting devices in file cabinets has gradually been valued. For a file cabinet, the main role of a lighting device is to provide a clear field of vision for the user in an insufficient light environment, so as to facilitate the quick and accurate searching and retrieval of archive files. In some large archives rooms or indoor spaces with relatively dark light, good lighting can greatly improve the efficiency of archive management and reduce the misoperation or difficulty in searching caused by light problems.

[0003] The Chinese utility model patent with publication number CN221533220U (application number CN202323641498.3) discloses a file cabinet, which comprises a cabinet body, a shelf, a conveying device, a driving member, a control member and a door body. The conveying device comprises a transmission member, a driven member, a conveying belt and a plurality of fixing members provided with clamping grooves. The transmission member and the driven member are arranged on the shelf from inside to outside. The conveying belt is connected to the transmission member and the driven member. The fixing members are connected to the conveying belt. The driving member is arranged between the transmission member and the driven member and is connected to the transmission member. The file cabinet of the present application is provided with a conveying device inside the cabinet body, which realizes the movement of the fixing members in the cabinet body along the inside-outside direction, thereby realizing the movement of the archives placed on the fixing members in the cabinet body along the inside-outside direction, facilitating the operation personnel to take and store the archives in the deep part of the file cabinet. The file cabinet of the present application can be set to a relatively wide width according to the actual use space and scene.

[0004] The above-mentioned file cabinet only provides a simple lamp at the top of the cabinet body, such as a straight tube fluorescent lamp or a common incandescent bulb lamp. This layout makes the light distribution uneven, the light is too strong near the lamp, which is easy to produce glare, and the light is dim in the area far away from the lamp, especially in the lower layer and corner position of the cabinet body, which cannot meet the requirement of uniformity of light for archive review. For example, in a multi-layer file cabinet, the top layer files may be brightly lit, but the bottom layer files may be difficult to see the content due to shadow blocking, and the user often needs to use a flashlight or other additional tools to view, which is extremely inconvenient. UTILITY MODEL CONTENTS

[0005] Therefore, the utility model provides a file cabinet lighting device, which solves the problem of uneven light distribution of the traditional file cabinet and improves the accuracy and efficiency of archive review.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a filing cabinet lighting device, including a cabinet body, shelves, a lighting device, a control component, and a door. The cabinet body has at least one open side, and multiple shelves are spaced apart inside the cabinet body. The control component is located on the side of the shelf near the cabinet opening. The lighting device includes a light strip, a mounting bracket, and a connector. The light strip is mounted on the lower surface of the shelf near the edge of the opening via the mounting bracket. The lighting device also includes a power supply line, with its two ends connected to the light strip and the connector, respectively. The control component is electrically connected to the connector. The door is rotatably connected to the cabinet opening.

[0008] Based on the above technical solution, the filing cabinet lighting device of this utility model can be further improved as follows:

[0009] The fixing frame includes a clamping part and an adhesive part. The clamping part is used to clamp the edge of the shelf, and the adhesive part is used to fix the light strip. The clamping part and the adhesive part are integrally formed.

[0010] Furthermore, the clamping part is C-shaped, and its opening width is smaller than the thickness of the shelf. The inner wall of the clamping part is provided with a rubber anti-slip pad for clamping the edge of the shelf.

[0011] Furthermore, the light strip is a cuttable LED light strip.

[0012] Furthermore, the inner walls on both sides of the cabinet are provided with corresponding guide grooves, and the two ends of the shelf are slidably connected by sliders embedded in the guide grooves.

[0013] Furthermore, the functional surface of the adhesive part is made of silicone.

[0014] Furthermore, reflectors are provided at both ends of the light strip. The reflectors are semi-cylindrical with their concave surfaces facing the inside of the cabinet. The reflectors are made of white PC material.

[0015] One side of the reflector is fixedly connected to the end of the light strip by two symmetrically arranged L-shaped metal pieces. One end of the L-shaped metal piece is welded to the side of the reflector, and the other end is fixed to the metal substrate at the end of the light strip by screws. This can reflect light into the cabinet and improve lighting efficiency.

[0016] Furthermore, the clamping part and the adhesive part are made of aluminum alloy.

[0017] Furthermore, the connector is a waterproof connector, and the connector is located at the bottom of the side of the cabinet.

[0018] The connection plug model can refer to: waterproof plug connectors of Shenzhen Wanshenxiang Technology Co., Ltd., and aviation plug waterproof connectors of Guangdong Zhonglian Electronics Co., Ltd.

[0019] A circular groove matched with the waterproof plug shape is arranged at the bottom of the cabinet side, two circular through holes are arranged at the bottom of the groove, two threaded columns are correspondingly arranged on the shell of the waterproof plug, the threaded columns are passed through the through holes and fastened by nuts, so that the waterproof plug is fixed at the bottom of the cabinet side.

[0020] Further, the power supply line is a multi-core shielded line, and the outside is covered with a fireproof insulating layer made of silicone rubber.

[0021] The power supply line is an RVVP model multi-core shielded line. RVVP is a copper core polyvinyl chloride (PVC) insulated shielded polyvinyl chloride sheathed flexible cable.

[0022] Compared with the prior art, the beneficial effects of the file cabinet lighting device provided by the utility model are:

[0023] The file cabinet lighting device adopts a unique lighting layout design. The light-emitting lamp strip is installed on the lower surface of the layer plate near the opening edge through the lamp strip fixing frame. Since an independent light-emitting lamp strip is arranged on each layer, compared with the traditional way of arranging lamps only on the top of the cabinet, close-range lighting of each layer of files can be realized. For example, in a five-layer file cabinet, the light-emitting lamp strip of each layer can directly provide lighting for the files of the layer, avoiding the light shielding of the upper layer of files to the lower layer of files, so that the light distribution in the whole cabinet from the top layer to the bottom layer is more uniform. Moreover, the light-emitting lamp strip is a cuttable LED lamp strip, whether the text content or the picture information of the files is clear and identifiable, effectively improving the accuracy and efficiency of file consultation.

[0024] The length of the light-emitting lamp strip can be cut according to the length of the layer plate, which can well adapt to layer plates of different sizes of file cabinets. Moreover, a reflector is arranged at each end of the light-emitting lamp strip, the reflector is a semicylindrical white PC material, the concave surface faces the inside of the cabinet and is fixedly connected with the end of the light-emitting lamp strip through an L-shaped metal sheet. The design of the reflector can reflect the light emitted from the end of the lamp strip to the inside of the cabinet, further expanding the lighting range and reducing the light dead angle. Even in the corner position of the file cabinet or the area close to the edge, sufficient light illumination can be obtained, so that the entire inside space of the file cabinet is in a good lighting state, and the user does not need to worry about missing files or difficulty in finding files due to insufficient light.

[0044] Specifically, the principle of the utility model is as follows:

[0045] In terms of optical principles, as the main light source, the light-emitting lamp strip has high luminous efficiency and stability. The LED light-emitting diode releases energy in the form of light by the recombination of electrons and holes in the semiconductor material. The soft light film pasted on the surface utilizes the scattering principle of light. The soft light film has many tiny particles or structures inside. When light passes through, multiple refraction and reflection occur, making the propagation direction of light more dispersed, reducing the concentration of light, and ultimately achieving soft light and avoiding glare. The semi-cylindrical design of the reflector and the white PC material are based on the law of reflection. The white PC material has high reflectivity to light. When light shines on the concave surface of the reflector, according to the law of reflection, light will be reflected at a specific angle towards the inside of the cabinet, thereby expanding the lighting range and improving the utilization of light.

[0046] In terms of mechanical structure design principles, the "C" shaped clamping part of the lamp strip fixing frame utilizes the friction principle to achieve fixation through the friction between the rubber non-slip pad and the layer plate. The selection of aluminum alloy material takes into account its mechanical strength and heat dissipation performance, which can withstand certain external forces and effectively dissipate the heat generated by the light-emitting lamp strip. The guide grooves on the inner walls of both sides of the cabinet and the sliders at both ends of the layer plate are based on the principles of sliding friction and mechanical guidance. When the slider slides in the guide groove, the shape of the groove can limit the movement direction of the slider, ensuring the stability and accuracy of the layer plate during sliding. At the same time, the sliding friction between the slider and the groove is not too large, making the adjustment of the layer plate relatively easy. The design of the multi-core shielding wire and the silicone rubber fireproof insulation layer of the power supply line is based on the principles of electrical protection and mechanical protection. The shielding wire can prevent external electromagnetic interference from affecting the signal of the line, and the silicone rubber fireproof insulation layer can mechanically protect the internal line from external force compression, wear and tear, etc., while electrically preventing short circuit of the line from causing a fire. The fixing method of the connection plug utilizes the fastening principle of threaded connection, which firmly fixes the plug at the bottom of the side of the cabinet through the cooperation of the nut and the threaded column, and when disassembly is needed, the connection can be easily released.
