The logo light emitting device of the portable computer generates power in a solar cell using the backlight of the LCD, and uses the power to emit an EL (Electric Luminance) area to provide light to the logo.

Alternatively, a light emitting device such as a light emitting diode may be installed directly on the rear side of the logo to cause the logo to emit light when power is applied.

However, the logo light emitting device of the portable computer is effective for a device that has a light source generating a lot of light, such as a backlight, but in a device without the light source, a separate light source for generating power to the solar cell has to be configured. Because of its use is extremely limited.

In the case of emitting a logo using a light emitting diode, the light emitting diode is positioned directly behind the logo, and the light of the light emitting diode is directly irradiated toward the logo. Therefore, when the size of the logo is large, the entire area of the logo is evenly distributed. It is difficult to provide light, and there is a problem that burdens the eyes of the user.

Accordingly, the present invention has been made to solve the above problems, it is easy to apply to various home appliances including the image display device, has a simple structure, provides light evenly over the entire area of the logo, indirect lighting method The purpose is to provide a light emitting logo assembly that does not burden the user's vision by providing a soft and subtle light emitting properties.

The logo portion 13 is formed on the front surface of the light guide member 12 in a negative pattern or embossed in a specific pattern, that is, a logo (logo) (13a) is integrally formed, only this portion other than the logo so that light can pass through The region may be painted in a dark color such as black. Of course, unlike the logo or transparent transparent carved tape or acrylic plate installed in front of the light guide member 12, only the logo portion may be configured to emit light while passing through.

In addition, the printed circuit board 14 is electrically connected to the main controller of the image display device, and controls the light emitting diodes 15 on / off depending on whether the image display device is powered.

In addition, the support frame 11 has a fixing piece (11a) is bent outwardly on both side portions are fixed to both sides of the opening (1a) of the cabinet 1, the upper and lower inner The upper and lower support pieces 11b and 11c, which are bent, are formed so that the upper and lower edges of the printed circuit board 14 are fixed by the support pieces.

The light emitting logo assembly 10 configured as described above operates as follows.

When a user applies power to the image display device, a control signal is transmitted to the printed circuit board 14, and the light emitting diode 15 is turned on to emit light downward.

Light emitted from the light emitting diodes 15 is guided forward while hitting the inclined surface of the light guide member 12. At this time, the light guided through the light guide member 12 is emitted through the logo 13a of the logo portion 13 so that the logo emits light.

In addition, when the logo 13a is emitted through the light guide member 12 as described above, part of the light emitted through the light emitting diodes 15 is reflected on the front surface of the printed circuit board 14. By being reflected by the light toward the light guide member 12, it is also possible to obtain an effect of preventing the loss of light irradiated from the light emitting diode 15 to a certain degree.

On the other hand, when the power of the image display device is turned off, the light emitting diodes 15 are also automatically turned off and the logo returns to the non-light emitting state.
