Description

Technical Field

[0001] The utility model belongs to the technical field of frameless light-emitting panels, and in particular relates to a frameless LED light-emitting panel. Background Art

[0002] At present, most billboards, interior decorations, and notice boards use incandescent lamps and fluorescent lamps as light sources, and have external light guide plates. Such light-emitting panels are large in size, inconvenient to transport and install, consume a lot of energy, are easily damaged, and have high operating costs. Existing light-emitting panels that use LED lamps as light sources simply replace the original light sources, and the structure of the light-emitting panels has not changed much. The existing light-emitting panels include a body, a reflective layer, and LED lamps. The body is made of transparent plastic or transparent organic glass. The body is an ultra-thin plate with lamp holes evenly arranged on the back and sides of the body; the LED lamps are embedded in the lamp holes; the reflective layer is attached to the side of the body with the reflective surface facing inward. Due to the limitation of the profile, the light-emitting surface of the assembled light-emitting panel has a certain width of the frame, which makes it impossible for the entire light-emitting area of ​​the light-emitting panel to emit light, affecting the light-emitting effect.

[0003] To this end, a frameless light-emitting panel with announcement number "CN210567593U" includes a light-emitting panel profile arranged around the panel. The light-emitting panel profile has multiple slots extending inwards from top to bottom, including a light guide plate slot and a corner bracket fixing slot. The light guide plate slot is used to secure the light guide plate. A reflective film is applied to the bottom of the light guide plate, and an LED light source is positioned inside the slot. An acrylic diffuser is positioned above the light-emitting panel profile. The light guide plate converts point light sources into surface light sources, thereby emitting uniform and soft light across the entire panel. Its ultra-thin design greatly improves space utilization and provides greater flexibility. It is also suitable for seamlessly joining multiple light-emitting panels later.

[0004] However, for the above-mentioned frameless light-emitting panel, although the point light source is converted into a surface light source by using a light guide plate, so that the entire light-emitting panel emits uniform and soft light, and its ultra-thin feature will greatly improve the utilization of space and be more flexible, the following more obvious defects still exist during use: However, the light-emitting panel is inserted into the light-emitting panel profile, and when the light source is turned on, a large black edge will appear on the side of the light-emitting panel, and the light emitted by the light source panel cannot be fully illuminated, and can only be used to observe images.

The light guide 3 adopts laser light guide point technology. The light guide 3 is a 4mm academic-grade extruded light guide plate, three-speed low-focus machine dotting, aluminum strip, and light strip driver;

[0025] An LED light source substrate 4 is provided with an L-shaped fixed plate 5 on one side of the outside of the LED light source substrate 4, and a bonding aluminum sheet 6 is provided at the bottom end of the inner side of the fixed plate 5. The bonding aluminum material model is 3M9495LE double-sided tape (width 3mm). The surface of the bonding aluminum sheet 6 is provided with a frosted reflective sheet 7, and the side of the frosted reflective sheet 7 is provided with a double-sided glue 8 for bonding and connecting with the light guide plate 3.

The LED light source substrate 4 is bonded to the bottom of the light guide plate 3 through the fixing plate 5 so that the LED light source substrate 4 is attached to one side of the light guide plate 3, so that the light source generated by the LED light source substrate 4 is attached to one side of the light guide plate 3, so that the light source will not have scattered light. The luminous lamp beads 9 on the LED light source substrate 4 should be dense, and the spacing between each luminous lamp bead 9 should be less than 5.5MM. The number of LED lamp beads per meter should be 180-240 beads.
