[Industrial use]

The present invention relates to a pixel for an electric sign, and more particularly, to a pixel for an electric sign for easy mounting and dismounting and good heat dissipation effect.

[Prior art]

In general, an electric signboard composed of a plurality of pixels is used as a medium to convey various information (news breaking news, company introduction and product advertisement, traffic information, game information, stock price display, etc.) using moving characters and pictures. The electronic display board is formed by arranging a plurality of pixels holding a plurality of light emitting devices.

The number of pixels arranged above is determined by dividing the size of the installed electronic display board by the size of the pixel.

The display board configured as described above represents a character and a picture by blinking light emitting elements installed in each pixel according to whether or not power is applied to each pixel that is constantly arranged. In particular, when power is applied to each pixel in a certain order, characters and pictures are variously expressed, such as moving, stopping, and blinking.

A conventional pixel for an electric signboard is composed of a case and a light emitting part, and the case is composed of a body part accommodating the light emitting part and a mounting part formed on a rear surface of the body part and coupled to a main body of the electric sign board, wherein the light emitting part is a constant circuit. The substrate includes a patterned substrate and a plurality of light emitting devices that are uniformly arranged on the substrate, and one end of which is electrically connected to the substrate, and the other of which is connected to a connector of the display body.

As the light emitting device, a light emitting diode (LED) is mainly used, and the light emitting device includes a plurality of light emitting devices arranged on a substrate, and then the board is mounted on a body, and an epoxy resin or a silicone resin or urethane resin is used. The molding material is molded to the extent that the tip of the light emitting device is not locked.

When the electronic display board is installed outdoors, unlike the indoor pixel, an outdoor pixel having a shade that can cover sunlight is used.

In the mounting part formed on the back of the body part of the case of the conventional display board pixel, a screw hole with a female thread is formed in the center portion, a protrusion is formed above the screw hole, and a wire hole through which the wire passes is formed at the bottom. do.

The conventional method for mounting a pixel for an electric signboard on the electric signboard main body comprises inserting the projection of the mounting portion into a projection hole formed on the mounting surface of the signboard main body, and inserting a small screw through the fastening hole formed in the signboard main body. It is made by fastening to the screw hole formed in the mounting part. In the above, the connection of the electric wire is made by connecting to the connector provided at the end of the electric wire extending through the electric wire hole of the mounting portion and the connector provided on the electric sign body.

In the conventional pixel plate for constructing and mounting the mounting unit as described above, it is difficult to accurately match the mounting position, and since it is necessary to connect the connector again after tightening a small screw, it takes a long time for mounting.

In addition, there is a problem that it is difficult to dissipate heat generated in the above-described light emitting part because the mounting plate of the pixel for the electronic display board and the mounting surface of the display board main body is attached to each other.

[Means for solving the problem]

Means to devise the present invention to solve the above problems consists of a light emitting portion that is arranged in a plurality of light emitting elements, a body portion to accommodate the light emitting portion and a mounting portion formed on the back of the body portion and the heat dissipation portion is formed It is to provide a pixel for an electric signboard composed of a case.

The light emitting unit includes a substrate on which a predetermined circuit pattern is formed, a plurality of light emitting devices arranged on the substrate, and a connector on one side of which is electrically connected to the substrate and the other of which is connected to a connector of the display board body. Included wires.

The mounting portion is formed on the back of the body portion is a portion of the side portion of the body portion is formed to extend and a plurality of support portions for forming a plurality of heat dissipation portion, and formed in the center of the back of the body portion and the projection for determining the mounting position and the The connector includes a connector inserting groove into which the connector of one light-emitting part wire is inserted and fixed, and a coupling part including a female screw part having a female thread. The outer periphery of the coupling portion is further formed with a sealing groove into which the sealing member is inserted.

In addition, the side of the coupling portion is formed with a plurality of heat dissipation member for dissipating heat generated in the light emitting portion.

A mounting hole corresponding to the female screw portion of the mounting portion is formed on the mounting surface of the display panel main body, and a connector is connected to the connector of the light emitting portion wire.

[Functions and actions]

The pixel for the inventive signboard configured as described above inserts the projection of the mounting portion into the projection hole formed in the mounting surface of the display panel main body, and connects the connector of the light emitting part wire inserted into the mounting portion connector insertion groove. After connecting to the collector of one of the display panel bodies, it is attached to the display panel body by fastening a small screw to the female threaded portion of the mounting portion through a coupling hole formed in the mounting surface of the display panel body.

The pixel of the present invention, which is mounted as described above and arranged in the display panel main body, is positioned by connecting the projections and the connector of the mounting portion to the corresponding projection holes and connectors formed on the mounting surface of the designated display panel main body, respectively, for positioning. It is mounted at a fixed position by fastening screws.

In addition, since the end surface of the mounting portion supporting portion is brought into contact with the mounting surface of the display panel main body, and the heat dissipation portion is formed in the supporting portion, heat generated in the light emitting portion is dissipated through the heat dissipation portion. That is, as air passes through the heat dissipation unit, heat is conducted from the light emitting unit to the mounting unit. Furthermore, when a plurality of heat radiating members are formed at the engaging portion of the mounting portion, the heat is more efficiently dissipated.
