MULTICOLOR LIGHT-EMITTING COMPUTER INPUT DEVICE [0001]

The present invention relates to a computer input technique and more particularly to a light emitting diode having a color light guide cap for illuminating a press member and a light emitting diode for emitting light from a high temperature zone of an electronic device using a multi- Relates to a multicolor light emitting computer input device that can extend the lifetime of light emitting diodes, reduce maintenance costs, avoid affecting the feel of the user's hands during operation, and avoid configuration variations due to extended use.

With the rapid development of modern technology and the electronics industry, many kinds of consumer electronic products have been created and brought convenience to people. Most electronic devices have a keyboard, a mouse, a joystick or a light gun for inputting data or instructions. Many types of switch devices are made for use in many electronic products. The computer keyboard for a notebook computer has various shapes as compared with a computer keyboard for a desktop computer. Because notebook computers are lightweight, thin, small, and short, the computer keyboard for desk computers is not suitable for use with notebook computers.

Moreover, the keyboard position of the keyboard of the initial design laptop computer did not show any light. The user could not click the keyboard position of the keyboard correctly in dim light environment. To solve this problem, a notebook computer keyboard capable of emitting light was developed. As shown in Figs. 8 and 9, a notebook computer keyboard capable of emitting light is composed of a key switch structure A and a backlight device B. The key switch structure A comprises a bottom plate A1, a membrane circuit board A2 aligned on the top surface of the bottom plate A1, a membrane circuit board A2 arranged on the top surface of the membrane circuit board A2, A keycap A5 spaced from the top of the elastomer A31 and a link member A4 connected between the keycap A5 and the bottom plate A1. The backlight device B includes the light guide panel B1 arranged on the bottom surface of the bottom plate A1 and the light emitting device B11 arranged on one side of the light guide panel B1 and the light guide panel B1, And a reflecting light panel B2 arranged on the bottom surface of the reflecting mirror.

During operation, the light emitting device B11 emits light laterally into the light guide panel B1, and the reflective light panel B2 directs light from the light guide panel B1 toward the keycap A5 of the key- Direction. However, since the light emitting device B11 is located on one side of the light guide panel B1, the flat substrate C1 of the notebook computer C is connected to the keyboard accommodation chamber C0) and the keyboard can be smoothly received in the keyboard accommodation chamber C0 without damaging the light emitting device B11. However, after the mounting of the light emitting device B11 in the groove C11 in the keyboard accommodation chamber C0, the light emitting device B11 is positioned close to the internal components of the notebook computer C that generates heat during operation . In order to provide the groove C11 to the keyboard accommodation chamber C0, the thickness of the flat substrate C1 must be considerably increased (about 0.3 mm to 0.5 mm). Increasing the thickness of the flat substrate C1 should significantly increase the thickness of the product.

Furthermore, the light emitting device B11 can be disposed in the central region or the boundary region of the flat substrate C1. When the light emitting device B11 is disposed in the central area of the flat substrate C1, the central area of the flat substrate C1 is lowered when the user clicks the keyboard, .

Moreover, in order to meet user preferences and to increase competitiveness in the market, manufacturers must continuously create various technologies, functions, and products. As a result, notebook computers that use a variety of materials and have various colors, shapes, and / or surface treatments are constantly being developed and marketed. However, a typical light emitting keyboard simply uses a white light emitting diode to emit white light. In order to change the color of light, light emitting diodes of various colors will be used. However, light emitting diodes of various colors (blue, green and / or red light emitting diodes) will significantly increase the manufacturer's development costs.
