Description

PORTABLE COMPUTER HAVING LED INDICATOR

The present invention relates to a portable computer, and more particularly to a portable computer having an LED indicator.

Housing portions of a computer typically have an indicator light to provide a visual indication of whether computer operating components such as a hard disk are operating. It has one or more indicator lights that provide it to a computer operator. A typical indicator light structure includes a lens structure and a light emitting diode (LED). The lens is supported inside the housing and projected outwardly through opening. In addition, the LED device is supported behind the lens and functions to periodically shine light on the lens.

Various methods have been proposed for efficiently mounting a lens in a housing lens opening. For example, one conventional method of mounting a lens proceeds by forming a recess in the inner side surface of the housing and surrounding it with a lens.

In particular, a light emitting diode (LED) is widely used as a device capable of accurately determining the operating states of electronic devices mounted in a notebook computer, and the light emitting diode is a printed circuit board. and a board (PCB), which emits light in response to the electronic devices. The notebook is provided with a window on the notebook so that the result can be clearly seen visually when the light emitting diode is emitted. The window is made of a transparent material so that a user using a notebook can easily recognize the light emitted from the light emitting diode. That is, light emitted from the light emitting diode on the printed circuit board is diffused through the lens member using acrylic or plastic provided adjacent to the light emitting diode to the window on the housing.

However, the lens member using acrylic or plastic often causes a problem that the light emitting diodes are mixed. To prevent this, ribs are provided on the housing of the notebook computer. In order for the ribs installed on the housing to be coupled to the lens member, grooves are formed at regular intervals so that the ribs may be coupled to the lens member. In this case, the problem due to the mixed color may be prevented to some extent, but a problem in assembly, that is, a problem that is caused when the lens member is coupled to the housing or is broken, or the overall size of the lens member is extended to form the grooves at regular intervals. On the contrary, since there are many grooves, the strength becomes weak. In addition, a problem arises in that the structure of the housing is complicated to form ribs.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and to provide a portable computer having a new type of LED indicator that can prevent the mixing of light on the lens member while maintaining the strength of the lens member.

According to a feature of the present invention for achieving the above object, a portable computer having an LED indicator has a base, at least one light emitting member and a lens member. The base has a plurality of electronic devices and includes an upper housing and a lower housing with a window. The at least one light emitting member is located on the lower housing or the upper housing in proximity to the window and emits light in response to at least one of the electronic devices. The lens member has a first side, a second side, and a light shielding member, the first side being attached to the window and the light shielding member being attached to the second side. In addition, the at least one light emitting member is coupled to be positioned in the center of the light shielding member to serve to prevent the light from being distributed to the side.

In the present invention, the light shielding member includes ribs formed at regular intervals on the second surface such that each of the at least one light emitting member is positioned between a pair of adjacent ribs.

In addition, in the present invention, the light shielding member includes at least one cylinder formed at regular intervals on the second surface such that the at least one light emitting member is positioned in the corresponding cylinder. Further, in the present invention, the light shielding member is formed of an opaque material.

According to the portable computer having the LED indicator having such a configuration, since a groove is not formed on the lens member and the intensity is maintained at a constant level, breakage during assembly can be prevented, and the light shielding member is formed on the lens member. Since it is installed, the structure of the upper housing can be improved. And since the light shielding member is provided on the lens member, the light shielding effect is improved.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 4. In addition, the same reference numerals are denoted for the components that perform the same function in the drawings.

1 is a perspective view for displaying an LED indicator portion in a typical portable computer.

As shown in the dotted line, the window 104 of the portable computer 100 is formed at the front end side of the top housing 106 constituting the top surface of the base 102. The base 102 includes an upper housing 106, a lower housing 108, and a plurality of electronic devices (not shown). The reason why the window 104 is formed at the front end of the upper housing is that even when the display screen 110 of the portable computer 100 is closed to face the base 102. Visually determine whether light emitting diodes (LEDs) (not shown) installed in the base 102 are adjacent to the window 104 through the window 104 formed at the front end. To do so. In the case of a conventional mixed color problem on adjacent windows, that is, for example, a first window 112 responding to the first electronic device and a second window 114 responding to the second electronic device are described. The light emitting diode operating in response to the first electronic device may emit light when the light is emitted from the first window 112 even when the light is emitted from the second window 114. The problem in which is seen to be operated can be prevented by the structure described below. Referring to Figures 2a to 4 showing a preferred embodiment of the present invention as follows.

Figure 2a is an exploded perspective view showing that the rib is installed in the lens member according to a preferred embodiment of the present invention and Figure 2b is a coupling diagram for showing the state in which the lens member of Figure 2a is coupled.

2A to 4, the lens member 116 is coupled to the inner surface of the upper housing 106. And ribs 118 are formed on the lens member 116 to a predetermined height. The light emitting diodes 122 of the board 120 are coupled such that they are positioned in the middle of the pair of ribs 118, respectively. The lens member 116 has a first face 124, a second face 126, and a rib 118 that is a light shielding member. The lens member 116 is connected by the hook 125 as shown in FIG. 2A such that the first surface 124 is attached to the window 104 of transparent material formed in the housing 106. It is locked to the upper housing 106. Ribs 118, which are the light shielding members, are provided on the second surface 126 at regular heights at regular intervals. The ribs 118 are formed at regular intervals on the second surface, and the light emitting diodes 122 are positioned between the pair of ribs 118 so that the light emitted from the light emitting diodes 122 is dispersed laterally. It prevents it from becoming. The black coating is colored on the surface of the rib 118 to prevent the light from being emitted or to be formed of an opaque material. Each of the light emitting diodes 122 is located between a pair of adjacent ribs. Since the lens member 116 does not have grooves on the surface at regular intervals unlike in the related art, the strength is greatly improved compared to the conventional art, and the rib 118, which is a light shielding member, is formed on the lens member 116. The assembling property in the case of attaching the member 116 to the upper housing 106 is also improved.

In addition, since it is not necessary to form a rib having a complicated shape on the upper housing 106, the mold structure and the product structure of the upper housing 106 are also greatly improved.

Referring to FIG. 4, how light emitted from the light emitting diode is transmitted to the window 104 in the case of the above configuration will be described. 4 is a cross-sectional view illustrating a state of cutting along the line a-a 'of FIG. 2B. Light emitting diodes 122 mounted on the board 120 emit light in response to the electronic device (not shown). Then, a portion of the light emitted straight through the lens member 116 is emitted to the window 104 and the light scattered to the side is blocked by the rib 118 is not distributed to the side.

FIG. 3A is an exploded perspective view showing that a light shielding member having a cylinder shape is installed in a lens member according to a preferred modification of the present invention, and FIG. 3B is a light shielding member having a cylinder shape of FIG. 3A coupled to a lens member. This is a coupling diagram to show the status.

3A to 3B, the shape of the member 119 for shielding light emitted from the light emitting diode 122 on the second surface 126 of the lens member 116 may be modified. The light shielding member having a cylindrical shape and having the shape of the cylinder is also formed at regular intervals, so that at least one light emitting diode is positioned in the corresponding cylinder. Thus, a better light shielding effect can be obtained than conventional light shielding means.

According to the present invention, since no groove is formed on the lens member, the strength is maintained at a constant level, thereby preventing damage during assembly, and since the light shielding member is installed on the lens member, the structure of the upper housing Can be improved. And since the light shielding member is provided on the lens member, the light shielding effect is improved.
