Description

2. The new technology belongs to the technical field, in particular, one is about the required light-emitting button 2. The prior art notebook computers have been widely used quickly, because the computer may be used in various environments. In response to the above requirements, the first picture showing a self-illuminating foot is a key structure of a conventional keyboard. The key structure 10 is composed of a keycap 101, a connecting mechanism 102, of which 104 and a switch. Piece 105 and a bottom plate 106 are formed. When the key cap of the electric circuit board is used, the switching element 105 of the circuit board 104 can be pressed by the guide, and characters or symbols can be input. In situations where there is insufficient light, for example, ^ ', the light is usually dimmed. At this time, the user will not be able to see when the key I is pressed, so the keyboard with no light source is very inconvenient to use. < Fig. 2a and Fig. 2b show another conventional button, a crazy view and a sectional view, respectively. This key structure 20 is a light source 200, a remote light-emitting diode (LED) structure, placed above the circuit board 204, so as to shine upwards ~ under the side of the cap 201, It is not directly below. The reason is that there are other components such as the connecting mechanism 20 2 directly below the keycap 201. The light green 2 (^ key position is limited by the structure of other key components, so that the light source 200 can only be used. So for QQ
