A luminous keyboard comprises a housing, a keyboard and a light emitting portion. The keyboard and light emitting portion are held in the housing. The light emitting portion includes at least one housing trough and a lighting element held in the housing trough. The housing trough has at least one first recess portion and at least one second recess portion on the periphery. The first recess portion and second recess portion have respectively an inner wall formed a first curved surface and a second curved surface. The lighting element generates light projected to the first and second recess portions, and the light piercing through the first and second curved surfaces is transmitted towards the concave directions of the first and second recess portions. Thus the light advancing direction in the light emitting portion can be effectively controlled. |
