Illumination feature for electronic devices
The present disclosure provides an illumination feature for an electronic device. A light cone is used to direct light from a light emitter to an interior surface of a housing of an electronic device in one of a variety of geometric, alphabetic, or numerical designs.
1. An electronic device, comprising:
circuitry for performing a function, the circuitry comprising a circuit board and a light emitter mounted to the circuit board;
a housing that contains the circuitry, the housing comprising a cover; and
a light cone, disposed between the light emitter and the cover, comprising an annular projection surface for projecting a geometric outline onto an underside of the cover.
2. The electronic device of claim 1 , wherein the light cone is constructed from a clear material, and comprises:
a distal end comprising a depression formed in the clear material, the depression for covering the light emitter; and
a proximal end larger in diameter than the distal end, comprising the annular projection surface in the shape of the geometric outline.
3. The electronic device of claim 1 , wherein the light cone comprises a distal end configured to receive light from the light emitter, a body for channeling the light to a proximal end of the light cone, the proximal end abutting the underside of the cover.
4. The electronic device of claim 1 , further comprising:
a channel disposed into the underside of the cover, sized and shaped in conformity with the annular projection surface;
wherein the annular projection surface abuts the channel when the electronic device is assembled.
5. The electronic device of claim 1 , wherein the geometric outline comprises a circle.
6. The electronic device of claim 5 , wherein the annular projection surface of the light cone light comprises the circle.
7. The electronic device of claim 1 , further comprising:
driver circuitry coupled to the light emitter; and
a processor coupled to the driver circuitry;
wherein the processor causes the light emitter to activate upon a determination by the processor that a predetermined event has occurred.
8. The electronic device of claim 7 , wherein the predetermined event comprises opening a door or a window by a user.
9. An electronic device for projecting an illuminated, predefined geometric shape from an exterior surface of the electronic device, comprising:
a light emitter mounted to a circuit board;
a housing, comprising a cover, for containing the circuit board, the cover comprising a channel formed into an underside surface of the cover, the channel formed as a geometric outline; and
a light cone disposed between the underside surface and the circuit board, the light cone comprising an annular projection surface abutting the channel, sized and shaped in conformity to the geometric outline;
wherein light received from the light emitter is projected from the annular projection surface onto the channel and through the cover.
10. The electronic device of claim 9 , wherein the light cone comprises:
an internal, conical wall forming a first apex pointing towards a distal end portion of the light cone, the distal end portion comprising a depression sized and shaped to receive the light emitter; and
a second, internal wall formed into the distal end portion, forming the depression, the depression comprising a second apex pointing toward the first apex.
11. The electronic device of claim 10 , wherein the light cone comprises a polished, outer wall and the internal conical wall comprises a polished internal wall.
12. The electronic device of claim 9 , wherein the geometric outline comprises a circle.
