Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED flat panel light technology, specifically to a cleanroom explosion-proof LED flat panel light. Background Technology
[0002] Explosion-proof lamps are used in hazardous locations where flammable gases and dust are present. They prevent the electric arcs, sparks, and high temperatures generated inside the lamp from igniting the flammable gases and dust in the surrounding environment, thus meeting explosion-proof requirements. They are also called explosion-proof lamps or explosion-proof lighting fixtures. Different flammable gas mixtures require different explosion-proof ratings and types of explosion-proof lamps. Explosion-proof lamps can be divided into two main categories: gas discharge lamps and LED lamps. LED lamps can be further divided into two main categories: flat panel lamps and cylindrical cavity lamps. Flat panel lamps have a larger light-emitting area and can be embedded in walls, saving space. Therefore, flat panel lamps have a wider range of applications.
[0003] However, due to the presence of large amounts of flammable gases and dust in the workspace, environmental factors can easily cause corrosion or short circuits. Therefore, the lifespan of explosion-proof panel lights is typically short. When these lights need replacement, they are often discarded as a whole, meaning the internal LED chips, while still functional, cannot be recycled. This not only wastes resources but may also increase the risk of environmental pollution. Therefore, a cleanroom explosion-proof LED panel light is proposed. Utility Model Content
[0004] Based on this, the present invention aims to at least solve one of the technical problems existing in the prior art. To this end, an explosion-proof LED flat panel light for cleanrooms is proposed, which facilitates the partial replacement of faulty components, thereby extending the overall service life and reducing maintenance costs.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleanroom explosion-proof LED flat panel light, including a lamp body, the lamp body including a lamp frame, the inner wall of the lamp frame being fitted with multiple sets of LED strips along its circumference, the top edge of the lamp frame being fixed with a frame, the top of the lamp frame being provided with a light-transmitting plate, the bottom of the lamp frame being fitted with a cover, and the top of the cover being fitted with a light guide plate inside the lamp frame;
[0006] Inside the lamp frame, a lamp strip holder is fixed at the position corresponding to each group of lamp beads. The lamp beads are snapped into the lamp strip holder, and the circuit of two adjacent groups of lamp beads is connected by wires.
[0007] As a preferred technical solution, the front and back of the frame are provided with clearance grooves, and a handle is rotatably connected to the clearance groove by a damping shaft.
[0008] As a preferred technical solution, the lamp frame is made of non-conductive metal material, and the lamp frame and the frame are integrally cast.
[0009] As a preferred technical solution, the bottom of the cover is fixed to the bottom of the lamp frame with bolts, and the bottom of the lamp frame has multiple sets of bolt holes along its circumference.
[0010] As a preferred technical solution, two sets of elastic elements are fixed at both the front and rear of the lamp frame, and the two sets of elastic elements can be deformed by external force.
[0011] As a preferred technical solution, the side wall of the lamp frame is provided with a wire hole, through which an external wire can connect to the internal lamp bead strip to form a circuit.
[0012] In summary, the present invention has the following main advantages:
[0013] This utility model achieves partial replaceability through a modular LED strip design. When a single LED strip is damaged, only the faulty unit in the corresponding LED strip holder needs to be removed, without replacing the entire lamp. The snap-fit structure between the LED strip holder and the lamp frame, combined with the laminated encapsulation of the light guide plate and the light transmission plate, ensures optical performance while maintaining the airtightness of the explosion-proof cavity. The damping rotating handle at the frame, combined with the sealing bolt fixing structure, facilitates safe disassembly and maintenance in a cleanroom environment. Attached Figure Description

Detailed Implementation
[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0021] The embodiments of this utility model will be described below based on its overall structure.
[0022] A cleanroom explosion-proof LED flat panel light, such as Figures 1 to 5 As shown, the lamp includes a lamp body 100, which includes a lamp frame 110. Multiple sets of LED strips 150 are mounted on the inner wall of the lamp frame 110 along its circumference. A frame 111 is fixed at the top edge of the lamp frame 110. A light-transmitting plate 112 is provided inside the top of the lamp frame 110. A cover 140 is mounted at the bottom of the lamp frame 110. A light guide plate 130 is mounted inside the lamp frame 110 at the top of the cover 140.
[0023] Inside the lamp frame 110, a lamp strip holder 160 is fixed at the position corresponding to each group of lamp strips 150. The lamp strips 150 are snapped into the lamp strip holder 160, and the circuit of two adjacent groups of lamp strips 150 is connected by wires.
[0024] It should be noted that: right-angle strips 113 are fixed at the four inner corners of the light frame 110, and pressure strips are provided at the bottom of the light guide plate 130 and at the corresponding positions of each group of light strip holders 160;
[0025] The bottom of the cover 140 is fixed to the bottom of the lamp frame 110 with bolts, and the bottom of the lamp frame 110 has multiple bolt holes along its circumference.
[0026] When it is necessary to replace the LED strip 150, first use a tool to unscrew the fastening bolts at the bottom of the cover 140 to completely release the sealing structure at the bottom of the lamp frame 110; then, carefully remove the light guide plate 130 and the mating pressure strip 131 in sequence; during this process, the pressure strip 131 will completely detach from the top contact surface of the LED strip holder 160, thereby releasing the constraint on the LED strip 150; then, simply apply a slight external force to the faulty LED strip 150, such as gently pulling it, and it can be easily removed from its installation position and quickly replaced with a brand new LED strip 150. The entire operation does not require disassembling other components or the overall structure, effectively saving maintenance time and workload, while avoiding the discarding of the entire LED strip set, thus saving on its usage costs.
[0027] The light guide plate 130 is arranged parallel to the LED strip 150, and the light is reflected by it and then uniformly output through the light-transmitting plate 112.
[0028] Two sets of elastic elements 120 are fixed to the front and back of the lamp frame 110, and the two sets of elastic elements 120 can be deformed by external force.
[0029] During installation, first align the cover 140 with the pre-drilled hole in the ceiling and gently push it in to embed it. During this process, the elastic element 120 will be compressed by the ceiling hole (i.e., the ceiling joist structure) and undergo elastic deformation to adapt to the space. When the lamp body 100 is fully embedded in the hole, the elastic element 120 will automatically recover due to its material properties, generating a rebound force, thereby firmly clamping the lamp body 100 and stably embedding it in the ceiling, ensuring a stable and reliable installation.
[0030] The front and back of the frame 111 are provided with clearance grooves 114, and a handle 170 is rotatably connected to the clearance grooves 114 by a damping shaft.
[0031] During the subsequent disassembly and replacement of the internal LED strip 150, the operator applies an upward push to the handle 170 with their hand, causing the handle 170 to rotate smoothly around the damping axis. This causes the handle 170 to completely disengage from the edge structure, providing a stable and easy-to-operate attachment point for the hand to apply the required external force. This makes it easier to grip and remove the lamp body 100, ensuring that the disassembly process is efficient and safe.
[0032] Please refer to this carefully. Figure 2 The lamp frame 110 is made of non-conductive metal, and the lamp frame 110 and the frame 111 are integrally cast.
[0033] To prevent the lamp frame 110 from becoming electrified when the LED strip 150 ages, and to provide safety for maintenance personnel.
[0034] The side wall of the lamp frame 110 has a wire hole, through which external wires can connect to the internal lamp bead strip 150 to form a circuit.
[0035] The wire hole is located on the side wall of the lamp frame 110. An external power cord can be connected to the circuit of the lamp strip 150 through this hole, and a waterproof connector is provided to enhance the explosion-proof performance.
[0036] The parts of the device not covered herein are the same as or can be implemented using existing technologies.
[0037] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
