Abstract

A lighting keyboard is provided with at least one keyswitch, a support plate and a backlight module. The keyswitch has a keycap and a switch under the keycap. The support plate connects beneath the keycap by a support mechanism. The backlight module has a lighting board configured underneath the support plate and corresponding to the keycap. The lighting board includes a board, a first reflective layer and a circuit layer. The circuit layer is disposed on the board and includes a concave-convex structure and circuit traces. The circuit traces electrically connects with a light emitting unit. The first reflective layer covers the concave-convex structure to form microstructure regions.
