Integrated display window with indirect lighting member {UNIFICATION DISPLAY WINDOW HAVING INDIRECTNESS LIGHT EMITTED DIODE ILLUMINATOR}

The present invention relates to an integrated display window, and more particularly, to an integrated display window structure including an indirect lighting member which indirectly illuminates the light emitted from the LED element to the inner wall surface of the case on a substrate installed on the case back of the integrated display window. An integrated display window having a simplified indirect lighting member is provided.

An integrated display window is provided between the driver's seat and the passenger seat to provide information to the driver by displaying dial or button operation states such as air conditioning and audio. This integrated display window forms an illumination section for illumination therein.

The lighting unit of the integrated display window illuminates the light emitted from a light source such as an LED mounted in the case through the scattering member coupled to the mid-housing, which is an external assembly, through the multi-stage scattering, from the inner wall of the case and diffuses the diffuser. It is visible to the driver through the LCD panel as a back light, providing visibility for the driver to know the desired operating conditions.

On the other hand, the scattering member is an opaque plastic material which is installed directly in front of the LED element is a member for inducing to be irradiated indirectly by scattering the light irradiated in a direct manner from the LED to the side through the front.

However, since a scattering member for scattering light emitted from an LED element and an exterior assembly for fixing the scattering member are provided inside the case of the existing integrated display window, the manufacturing cost increases due to the complexity of the overall structure. The scattering member is weak to shock and easily broken.

Thus, there is a need for improvement.

The present invention has an indirect lighting member which indirectly illuminates the light irradiated from the LED element on the inner wall surface of the case on a substrate installed on the back of the case of the integrated display window, thereby simplifying the integrated display structure and reducing the manufacturing cost, impact It is an object to provide an integrated display window having an indirect lighting member that withstands well.

In order to achieve the above object, the integrated display window having an indirect lighting member according to an embodiment of the present invention, the LCD panel for providing the necessary information to the driver, fixing the LCD panel to the front, and forming a space therein It is installed in the lighting case and the space portion, and irradiates the light in the inner direction of the lighting case and indirect light member for scattering the light hitting the inner surface to provide a back light to the LCD panel.

In addition, the indirect lighting member is installed on a printed circuit board coupled to the rear of the lighting case is characterized in that provided in the space.

In addition, the indirect lighting member is molded on the printed circuit board, the body forming an open opening forward, an LED element installed on the bottom surface of the opening hole of the body, and molded in the opening hole of the body, It characterized in that it comprises a molding material for scattering the light irradiated from the LED element.

The indirect lighting member may further include a fixing part for fixing on the printed circuit board, wherein the fixing part protrudes from the side of the body and passes through a fixing plate for forming a through hole, and a through hole of the fixing plate. And a fastening member fastened to a screw hole formed in the printed circuit board.

The LCD panel may further include a frame coupled to the lighting case to fix the front surface.

The LCD panel may further include a diffuser on a rear surface to diffuse light scattered from the inner surface of the lighting case.

As described above, the integrated display window having an indirect lighting member according to the present invention includes an indirect lighting member which indirectly illuminates the inner wall surface of the case with light emitted from the LED element on a substrate provided on the case back of the integrated display window. Therefore, it is possible to delete the scattering member and the outer assembly to simplify the integrated display structure, reducing the manufacturing cost, and withstands shock well.

In addition, when the LED elements of different colors are used, two or more colors may be gradually changed so that a soft and soft mixed color appears to provide a beautiful aesthetic to the driver.

In addition, since the LED element can be installed without the help of an external assembly, it is possible to install the LED element in any direction in any direction.

Hereinafter, an integrated display window having an indirect lighting member according to an embodiment of the present invention will be described with reference to the accompanying drawings.

Display information about the situation.

The LCD panel 18 irradiates light having various colors from the rear since no letters and figures are displayed without a back light.

And, the LCD panel 18 further includes a frame 20 coupled with the illumination case 12 to fix the front surface.

The back of the LCD panel 18 is provided with a diffuser (diffuser) in order to diffuse the light irradiated from the rear through the indirect lighting member 30 to be seen.

The lighting case 12 fixes the LCD panel 18 to the front, and forms a space 14 therein.

The illumination case 12 is a hexahedron shape, and is formed to gradually open from the rear to the front.

Inside the lighting case 12 may be coated with a reflective layer for reflecting the light emitted from the indirect lighting member 30, the outside may be further provided with a locking member to be caught in the locking groove of the frame 20.

The indirect lighting member 30 is installed in the space 14, and irradiates light toward the inner side of the lighting case 12 to scatter light hitting the inner side to provide a back light to the LCD panel 18. do.

One or more indirect lighting members 30 are provided on the printed circuit board 22 coupled to the rear of the lighting case 12 and provided in the space 14 of the lighting case 12.

At this time, the indirect lighting member 30 is fixedly installed on the printed circuit board 22 by soldering, as shown in FIGS. 3 and 4.

The indirect lighting member 30 is located on the printed circuit board 22 and forms a body 32 which forms an open hole 38 which is opened forward, and a bottom surface of the opening hole 38 of the body 32. The LED element 34 is installed, and the molding member 36 is molded in the opening hole 38 of the body 32 and scatters light emitted from the LED element 34.

3 and 4, the indirect lighting member 30 is led to face the upper and lower inner surfaces of the lighting case 12 so that the direction irradiated with each other on the printed circuit board 22 is reversed. Two or more elements 34 may be disposed and installed. At this time, it is possible to configure a different color.

The colors displayed on the background surface of the LCD panel 18 by irradiating light of different colors are mixed so that the mixed colors appear where the different colors meet, and gradually appear to be unique colors as they go farther away, so that they appear soft and beautiful. Can be configured to

For example, when the LED element 34 of one indirect lighting member 30 is red, and the LED element 34 of the other indirect lighting member 30 uses blue, At the point where the light meets, a purple image appears, gradually fading or darkening, and then two or more colors gradually appear, turning into red and blue colors, respectively.

Of course, it is also possible to provide only one LED element 34 of the indirect lighting member 30 on the printed circuit board 22.
