摘要： A backlight module includes a light guide plate with a main body and a light source with a circuit board and a plurality of light bars. The main body has a light incidence surface and a light emitting surface. The light incidence surface has a plurality of accommodating grooves and the light emitting surface or the light incidence surface has a plurality of light-separation grooves which are perpendicular to the accommodating grooves. The accommodating groove has a first and a second light incidence parts. A reflecting layer is disposed on the surface of the circuit board being located between each two light bars. The light source is disposed on the light incidence surface and light bars are disposed for the accommodating grooves so as a predetermined distance located between the light bar and the second light incidence part is formed a light mixing space to reduce the production of bright lines.

摘要： A keyboard device includes at least an illuminant element, at least a pressing key element and a light guide element. The pressing key element includes a keycap reciprocating along a first axial direction when being pressed and a recovering component attached to the keycap for supporting and pushing back the keycap when not pressed. The light guide element is located at one side of the recovering component. The light guide element includes at least a light-incident part and a light-emitting part. The light-incident part is used for receiving light emitted from the illuminant element. The light-emitting part emits light along a second axial direction to the recovering component so that the recovering components guide light to the keycap, wherein the second axial direction is different to the first axial direction.

摘要： A backlight module includes a light guide plate and a lighting source. The light guide plate has a main body with a light incidence surface and a light emitting surface. A plurality of accommodating grooves are provided on the light incidence surface, and a plurality of light-separation grooves which are perpendicular to the accommodating grooves are provided on the light emitting surface. The light source includes a circuit board and a plurality rows of light bars welded on the circuit board, where each light bar is composed of a plurality of light emitting diode. When the light source is assembled to the main body, the circuit board is attached to the light incidence surface such that the light bars are disposed for the corresponding accommodating grooves. Therefore, the light-separation grooves can effectively optically separate the light when the light bars are illuminated.
