Computer panel with light-reflecting and light-shielding member

A panel assembly for a computer, comprising:

• a computer panel comprising a light-pervious area and an opaque portion surrounding the light-pervious area;
• a mounting apparatus mounted to the panel;
• a light source for emitting light rays fixedly secured to the mounting apparatus;
• a light-reflecting member pivotally mounted to the mounting apparatus and obliquely rotated relative to the light source, the light-reflecting member having a cavity, a toothed engaging member, and a light-pervious portion, the light source being received in the cavity, the light-reflecting member being configured for reflecting the light rays to exit from the light-pervious portion;
• and
• a rotary gear member meshed with the toothed engaging member of the light-reflecting member;
• the rotary gear member is rotatable such that the light-reflecting member is driven to rotate between a first position where the light-pervious portion is aligned with the light-pervious area and second position where the light-pervious portion faces toward the opaque area.
