Description

Technical Field

[0001] This utility model belongs to the field of panel light technology, and in particular relates to a panel light with a sealing structure. Background Technology

[0002] LED panel lights are high-end indoor lighting fixtures. Light passing through a high-transmittance light guide plate creates a uniform planar light emission effect, providing excellent illuminance uniformity, soft, comfortable yet bright light, effectively relieving eye fatigue. LED panel lights also offer radiation protection and will not irritate the skin of pregnant women, the elderly, or children.

[0003] For example, patent CN217928502U discloses a sealed panel light that safely prevents internal water ingress, relating to the field of decorative lighting device technology. It addresses the problem that when water vapor seeps into most panel lights, it easily evaporates due to the heating of the light panel, then condenses and drips, affecting the lifespan of the panel light. The design includes a panel light frame, a guide frame, and a sealing partition. The panel light frame has a carrying groove on its inner side and a carrying frame fixedly installed on its outer side. The guide frame is installed on the top of the panel light frame, with a conveying groove on its inner side and a connecting hole through its inner side. An assembly partition is fixedly installed on the top of the panel light, and a heat-conducting groove is formed on the top of the assembly partition. The assembly partition carries and conveys the dripping water droplets, while the conveying groove, in conjunction with the conveying groove, guides and transfers the water droplets, thus allowing the connecting hole to engage with the conveying hole, transporting the water droplets into the carrying frame, and then discharging them through a spiral groove.

[0004] Existing panel lights with sealed structures are difficult to install and remove, and their sealing performance deteriorates after installation and removal. Therefore, we propose a panel light with a sealed structure. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a panel light with a sealed structure, thus avoiding the difficulty in disassembling and assembling panel lights.

[0006] In view of this, the present invention provides a panel light with a sealing structure, including a mounting frame, a screw provided on the inner wall of the mounting frame, a telescopic plate threadedly connected to the outer wall of the screw, guide grooves provided at both ends of the telescopic plate, guide posts movably connected to the inner wall of the guide grooves, a sliding plate fixedly connected to the bottom end of the guide posts, a limit rod penetrating through the inner wall of the sliding plate, an active pressure plate fixedly connected to one end of the sliding plate, a driven plate attached to the side wall of the active pressure plate, a cover plate fixedly connected to the outer wall of the driven plate, a panel light frame provided at the bottom end of the cover plate, and a sealing gasket provided at the connection between the panel light frame and the cover plate;

[0007] A panel light assembly, located inside a panel light frame, for sealing the panel light frame.

[0008] Based on the above structure, the guide groove slides and drives the sliding plate at one end of the guide post to slide along the outer wall of the limiting rod. The sliding plate drives the cover plate at one end of the driven plate to fit tightly with the panel light frame through the active pressure plate, thereby tightly fitting the sealing gasket between the cover plate and the panel light frame, realizing the sealing operation of the panel light frame. At the same time, it facilitates the disassembly and assembly of the panel light frame and the replacement of the internal parts of the panel light frame.

[0009] Preferably, the guide groove is inclined, and the sliding plate forms a sliding structure with the guide groove, the guide post, and the limiting rod. In this embodiment, the screw rotation drives the guide groove to slide through the telescopic plate, and the sliding of the guide groove drives the sliding plate at one end of the guide post to slide along the outer wall of the limiting rod, thereby realizing the control operation of the sliding plate sliding.

[0010] Preferably, the connection surfaces of the active pressure plate and the driven plate are inclined. In this embodiment, this facilitates the sliding plate to drive the cover plate at one end of the driven plate to fit tightly against the panel light frame through the active pressure plate, thereby achieving the pressing operation on the driven plate.

[0011] Preferably, the cover plate forms a pressing structure with the panel light frame through an active pressure plate and a driven plate. In this embodiment, the sliding plate drives the cover plate at one end of the driven plate to fit tightly with the panel light frame through the active pressure plate, thereby tightly fitting the sealing gasket between the cover plate and the panel light frame, realizing the sealing operation of the panel light frame. At the same time, it facilitates the disassembly and assembly of the panel light frame and the replacement of the internal parts of the panel light frame.

[0012] Preferably, the panel light assembly includes:

[0013] The light strip is fixedly connected to the inner wall of the panel light frame. A light guide plate is provided on one side of the light strip. A reflective film is attached to the top of the light guide plate, and a diffuser plate is provided at the bottom of the light guide plate. An isolation gasket is provided at the connection between the panel light frame and the diffuser plate. In this embodiment, by setting an isolation gasket with an "L" shaped cross-section, the diffuser plate is sealed to prevent moisture from entering the interior of the panel light frame through the diffuser plate. Then, when the light strip is powered on, it generates a light source. The light enters the light guide plate and is illuminated by the diffuser plate. At the same time, the light is reflected by the reflective film and then passes through the diffuser plate, which helps to improve the brightness of the light.

[0014] Preferably, the light strip is provided in two sets, and the two sets of light strips are symmetrical about the light guide plate. In this embodiment, by providing two sets of light strips, it is beneficial to provide uniform illumination.

[0015] Preferably, the cross-section of the insulating gasket is "L" shaped. In this embodiment, by setting an insulating gasket with an "L" shaped cross-section, the diffuser plate is sealed to prevent moisture from entering the interior of the panel light frame through the diffuser plate.

[0016] The beneficial effects of this utility model are:

[0017] 1. This panel light with a sealing structure uses an active pressure plate to drive a driven plate. The guide groove slides, causing a sliding plate at one end of the guide post to slide along the outer wall of the limiting rod. The sliding plate, through the active pressure plate, causes the cover plate at one end of the driven plate to fit tightly against the panel light frame, thereby tightly fitting the sealing gasket between the cover plate and the panel light frame, achieving a sealing operation for the panel light frame. At the same time, it facilitates the disassembly and assembly of the panel light frame and the replacement of internal parts.

[0018] 2. This panel light with a sealed structure uses an L-shaped insulating gasket to seal the diffuser plate, preventing moisture from entering the interior of the panel light frame through the diffuser plate. Then, when the light strip is powered on, it generates a light source, which enters the light guide plate and illuminates the light through the diffuser plate. At the same time, the light is reflected by the reflective film and then passes through the diffuser plate, which helps to improve the brightness of the light. Attached Figure Description
