Easy to repair LED sign board frame

This creation department is about an LED sign board, especially an LED sign board frame that can be easily and quickly repaired by replacing the LED strip.

According to the popularization of Light Emitting Diode (LED), and the size and power consumption of LEDs are smaller than fluorescent lamps, LED sign boards can be made. The principle is to use LED light to change. The path, which will be placed on the side of the "line source", uses the principle of total reflection plus refraction to direct the light to be emitted in the forward direction, producing a "surface source" effect with uniform luminosity.

The conventional LED sign board comprises: a frame body, a light guide plate, a back plate, a kanban plate and at least one LED light bar, wherein the frame body is a combined structure, the light guide plate has a light incident surface, and the light guide plate The backplane and the kanban are disposed in the frame, and the at least one LED strip is mounted on the inner side of the frame and abuts against the light incident surface of the light guide. In use, the light emitted by the LED strip passes through the light guide plate, and the light source is uniformly irradiated to the viewing panel through the light guide of the light guide plate, so that the content of the advertisement, the notice text or the pattern on the billboard can be clearly defined. Presented.

However, when the LED strip is damaged and needs to be replaced, the LED strip must be disassembled, the light guide, the back panel and the kanban removed, and the LED strip installed on the inner side of the frame can be taken out. Perform the replacement action, and after the replacement, reassemble the frame and turn the light guide plate and back The board and the kanban group are clamped in the frame, which is not only troublesome and time consuming, but also causes damage to other components such as the light guide plate, the back plate and the kanban during the replacement process, so it is necessary to improve.

The creator has the trouble of replacing and repairing the LED strips in view of the conventional LED sign board, and it is easy to cause damage to other components during the replacement process. It is the idea of creating and testing the samples, and After many revisions and improvements, I finally designed this creation.

The present invention provides an LED sign board frame that can be easily repaired, comprising: a frame body, a light guide plate, a back plate, a kanban plate and at least one LED light bar, wherein the frame body is a combined structure, the inside of the frame body a light strip sliding slot is disposed on the outer side of the frame, and at least one of the outer side of the frame is disposed to communicate with the light bar sliding slot. The light guiding plate has a light emitting surface, a rear surface opposite to the light emitting surface, and at least one of the light connecting surfaces The light-incident surface between the light-emitting surface and the back surface is printed or affixed with an advertisement, a text or a pattern of a notice, and the light guide plate, the back plate and the kanban are arranged in parallel in the frame, and the back is The LED is disposed on the back side of the light guide plate, and the illuminator is disposed on a side of the light-emitting surface of the light guide plate. The LED light strip has a carrier strip and a plurality of LED components disposed on the carrier strip. The light strip sliding slot of the frame is assembled, the LED element and the light incident surface of the light guide plate are abutted, and the LED light strip is formed by the punching hole of the frame penetrating into the light bar chute, and the light strip can be drawn Replace the hole for replacement.

The main purpose of this creation is that when the LED light bar is damaged and needs to be replaced and repaired, the LED light bar can be directly replaced without disassembling the frame body, thereby achieving convenient and rapid benefits.

The second purpose of this creation is that it can be straight without disassembling the frame. The replacement of the LED light bar is facilitated, so that the replacement process does not cause damage to other components such as the light guide plate, the back plate and the kanban, and the utility is improved.
