When installing, it is necessary to add 5-10 mm of installation space.

  Traditional method B: As shown in Fig. 2-4, a lamp groove is provided on one side of the acrylic light-emitting plate body 1, the LED lamp bar 3 is fixed in the lamp tank, the LED lamp bar and the edge of the acrylic light-emitting plate body Since it is necessary to install the L-shaped aluminum connection plate 4 and the lamp groove in between, the edge of the acrylic light emitting plate body is several millimeters thick, and in addition to the thickness of the lamp tank, this LED The light emitting point of the light emitting plate is 5-10 mm from the end of the LED light emitting plate, and this 5-10 mm is not illuminated, and the edges of all LED light emitting plates are darkened.

  For this reason, the user must consider this edge special processing of 5-10 mm at the time of installation, and the final product and the whole product are not satisfied with the light emitting surface.

  In addition, the connection destination of the existing LED light-emitting plate power line and LED light bar is only connected by tin welding, there is no protective measure, and in addition, the power line has a certain length and weight, so that the user can use or During installation, it is easy to accidentally disconnect the LED light bar from the power cord, and the light-emitting plate will be turned off, making it unusable.

  An object of the present invention is to provide an LED light-emitting plate having no dark edge, to emit light over the entire light-emitting surface, to improve the use effect, and to solve the problem that the power line is easily cut off.

  In order to solve the above problems, the present invention provides an LED light emitting plate without a dark edge including a light emitting plate body and an LED lamp bar, and LED beads are attached to the LED lamp bar. There is a gap on one side of the light surface, a light emitting surface and a convex base are formed, an LED lamp bar is attached to the gap of the light emitting plate body, an L-shaped aluminum connection plate is attached to the side of the convex base, The L-shaped aluminum connecting plate is fixed to the side surface of the convex table with heat conductive double-sided tape, and the back surface of the L-shaped aluminum connecting plate is fixed to the backlight surface of the light emitting plate body.

  Furthermore, the L-shaped aluminum connection plate is a backlight surface of the light-emitting plate body fixed by a double-sided tape or an aluminum tape.

  Further, reflective paper is attached between the L-shaped aluminum connecting plate and the backlight surface of the light emitting plate body.

  Further, a V-shaped mouth is provided on the back surface of the light emitting plate body.

  Further, the width of the convex base is 1-2 mm.

  Further, the light emitting plate body is provided with a power line mounting groove on the side where the LED lamp bar is mounted. The power line mounting groove is provided on the back surface of the light emitting plate body, and the power line emits light. Wires can be routed from the back or side of the plate body.

Further, the power line is fixed to the power cable mounting groove using a transparent AB adhesive or a transparent hot melt.
Further, the wire mounting groove has an L shape or a U shape.

  Further, the light emitting plate body is an acrylic light emitting plate.

Employing such a design, the present invention has at least the following advantages.
The LED light-emitting plate of the present invention is held on the side surface of the light-emitting plate main body by a 1-2 mm light-emitting plate main body, and an L-shaped aluminum connection plate is bonded to the side of the convex base using heat conductive double-sided tape A small space was formed between the L-shaped aluminum connection plate and the convex base, and the LED lamp bar was installed in this space. If such a design is adopted, not only the LED light bar is protected from external collisions, but also the L-shaped aluminum connecting part plays a role of heat dissipation and dissipates the amount of heat generated from the LED light bar in a timely manner. Can do. The LED light emitting plate of the present invention can attach an LED light bar to the outermost end of the light emitting plate body, the light emitting surface of the LED light emitting plate does not require tape or aluminum alloy treatment, and after the LED light is irradiated, The edge width is only 1-2 mm, and because of the reflection of light and the judgment error of the naked eye, the 1-2 mm edge cannot be recognized by the naked eye and can be almost ignored. Thereby, the visual effect that the whole light-emitting plate is bright is obtained. In this way, there is no need to add 5-10 mm of mounting space when installing the LED light-emitting plate, the front of the light-emitting plate is all bright and unobstructed, maximizing user space utilization and It can satisfy complex design needs and give the user a better feeling of use.

  In the traditional method A, the light-emitting surface of the light-emitting plate is 1 to 2 mm thicker than the entire light-emitting surface, increasing the packaging volume, increasing the transport difficulty and transport cost, and increasing the installation space. . The light emitting surface of the light emitting plate of the present invention does not need to be increased in thickness, the light emitting surface is flat, and packaging, transportation, and mounting are convenient.

  The power supply line of the present invention is fixed to the mounting groove of the power supply line. When the power supply line is pulled by an external force, the power supply line is not easily pulled, and the welded portion between the power supply line and the LED lamp bar is not easily torn. The connection point is well protected and not affected by external force.

  The present invention effectively solves the problem of a dark edge on the side of an existing LED light-emitting plate lamp, makes the entire light-emitting plate emit light, and appears to have no dark edge. This structure is simple, but it well solved the thinking mode between the front edge of the LED light-emitting plate 5-10 mm and the dark area. The present invention uses the visibility of the human eye to ignore the 1-2 mm light emitting area, brings about the light emitting effect of the entire light emitting plate, solves major problems in the industry, and has significant significance. As the industry advances, more complex and high-end design philosophy can be satisfied.
