Patent ID: 8325472

Claim:
An electronic apparatus, comprising: a mainframe with a keyboard embedded therein; a display screen; a mounting frame pivotally connected with the mainframe with the display screen mounted in the mounting frame; a lighting source disposed on the mounting frame; and an optical element cooperating with the lighting source and slideably mounted on the mounting frame, light from the lighting source being projected to different predetermined areas by adjusting positions of the optical element relative to the lighting source, wherein in each of the positions of the optical element, the light from the lighting source is modulated by a corresponding portion of the optical element to be projected to a corresponding predetermined area; wherein the lighting source is an LED light source, and the optical element covers the LED light source and comprises a plurality of interconnected optical lenses, when the optical element is caused to slide to a predetermined position relative to the LED light source to make a predetermined optical lens in alignment with the LED light source, the light from the LED light source extends through the predetermined optical lens and is modulated into a beam with a certain illumination range; and wherein the optical element comprises a first optical lens and a second optical lens, when the optical element is caused to slide to a first position relative to the LED light source, the light from the LED light source extends through the first optical lens and is projected on a first predetermined area in front of the display screen, and when the optical element is caused to slide to a second position relative to the LED light source, the light from the LED light source extends through the second optical lens and is projected on a second predetermined area where the keyboard is located.
