The lighting module comprises a light source, a backlight plate having a surface with light-reflective protrusions and a light-reflecting plate. In one embodiment, the thickness of the backlight plate varies linearly and the light source is located on the thicker side of the backlight plate. The light-reflecting plate reflects light beams reflected from the surface with light-reflective protrusions of the backlight plate and renders the keyboard illuminated.
