Abstract: A backlight module and a lighting keyboard using the same are provided. The backlight module includes a flexible circuit board, a light-emitting element, a light shielding layer and a light guide plate. The light-emitting element is disposed on the flexible circuit board. The light shielding layer is disposed on the flexible circuit board and surrounds the whole light-emitting element. The light guide plate has a through hole, the light emitting element is located within the through hole, and the light shielding layer is located between the substrate and the light guide layer.

Abstract: A keyboard frame with induction light source is disclosed, which comprises: a frame, a light guide plate, a signal line, a thermal sensor, a light source, a control circuit and a switch. As the light guide plate having the signal line disposed thereon is received in the frame while the thermal sensor and the light source is further disposed on the signal line and connected thereto, temperatures of a hand detected by the thermal sensor is transmitted to the control circuit where it is converted into electric signals and then send to the light source for directing the same to perform a color changing operation accordingly and thus cause the keyboard frame to display various coloring/lighting effects. With the aforesaid structure, not only the keyboard frame is fun to play for its ability to display various lighting/coloring effects, but also it is able to act as a thermometer for measuring human body's temperature.

Abstract: A keyboard. A membrane circuit assembly is disposed on a base plate. A key base is disposed on the membrane circuit assembly and comprises a first metal conducting portion and a second metal conducting portion. The first and second metal conducting portions are connected to a power source. An activating body is movably connected to the key base and comprises a third metal conducting portion and a fourth metal conducting portion. The third and fourth metal conducting portions are detachably connected to the first and second metal conducting portions, respectively. A light-emitting element is disposed on the activating body and connected to the third and fourth metal conducting portions. A keycap is disposed on the light-emitting element and connected to the activating body. The keycap drives the activating body to move, enabling the third and fourth metal conducting portions to respectively connect to the first and second metal conducting portions.
