1. A light guide configured for positioning proximate to a light emitter in an electronic device;
- said light guide comprising;
a first prism having a first position in relation to said light emitter;
said first prism having a first boundary defined by a first length and a first angle in relation to a plane parallel to a surface of said light emitter; and
,a second prism having a second position in relation to said light emitter;
said second prism having a second boundary defined by a second length and a second angle in relation to said plane; and
a plurality of additional prisms;
each of said prisms being substantially square in shape, arranged in a grid;
each of said additional prisms having surfaces defined by additional lengths and additional angles in relation to said plane, each decreasing in size according to a distance from said light emitter;
wherein said first position is closer to said light emitter than said second position and said second angle is less than said first angle.

Abstract
A light guide guides light from a light emitter that is adjacent to an aperture of an electronic device. The light is eventually emitted from the aperture, to thereby provide lighting. The light guide can include a plurality of prisms which can thereby permit reduction in the overall thickness of the electronic device.

14. An electronic device comprising:
-
a light emitter; a first prism having a first position in relation to said light emitter;
said first prism having a first surface boundary defined by a first length and a first angle in relation to emitted light from a plane parallel to a surface of said light emitter;
said first prism configured to reflect at least a portion of said emitted light away from said first surface; and
,a second prism having a second position in relation to said light emitter;
said second prism having a second boundary defined by a second length and a second angle in relation to said plane;wherein said first position is closer to said light emitter than said second position and said second angle is less than said first angle, an aperture proximate to said light emitter for transmitting light that is reflected from said first prism and said second prism. - View Dependent Claims (15, 16, 17, 18)
