CLAIMS

1. An electronic device, comprising:

a light source to emit a light;

a light guide coupled to the light source;

a camera having a privacy lens coupled to the light guide to receive light from the light source via the light guide to activate the privacy lens; and

a housing to enclose the light source, the light guide, and the camera having the privacy lens.

2. The electronic device of claim 1 , wherein the light source comprises an ultra violet light source.

3. The electronic device of claim 1 , wherein the light guide comprises a solid transparent material that provides total internal reflection.

4. The electronic device of claim 1 , wherein the light guide comprises a hollow material that has an interior lined with a reflective material.

5. The electronic device of claim 1 , wherein the privacy lens comprises: a plastic lens; and

an organic photochromic material coated on the plastic lens, wherein the organic photochromic material reacts when contacted with light.

6. The electronic device of claim 1 , wherein the light source, the light guide, and the privacy lens are located along a bezel of the housing.

7. An electronic device, comprising:

a light emitting diode (LED) to emit a light;

a light guide coupled to the LED;

a camera having a privacy lens coupled to the light guide to receive light from the LED via the light guide to activate the privacy lens; and

a privacy activation button coupled to the LED, wherein the privacy activation button is to power on the LED to emit the light to activate the privacy lens when pressed.

8. The electronic device of claim 7, wherein the LED comprises an ultra violet LED.

9. The electronic device of claim 7, wherein the light guide comprises a transparent plastic material.

10. The electronic device of claim 7, further comprising:

a first shade component over the LED; and

a second shade component around a portion of the light guide.

1 1. The electronic device of claim 10, wherein the first shade component comprises:

a piece of foil to cover the LED; and

a sponge to absorb any of the light that is emitted around the piece of foil.

12. The electronic device of claim 10, wherein the second shade component comprises a Mylar material.

13. The electronic device of claim 7, wherein the privacy lens comprises: a plastic lens; and

a layer of oxazines or napthopyrones having a thickness of at least 150 microns.

14. A non-transitory computer readable storage medium encoded with instructions executable by a processor, the non-transitory computer-readable storage medium comprising:

instructions to receive an indication to activate a privacy lens; and

instructions to activate an ultra violet (UV) light emitted diode (LED) to emit a UV light through a light guide towards a privacy lens of a camera, wherein the privacy lens is coated with an organic photochromic material that reacts with the UV light to turn black and is to prevent the camera from capturing images.

15. The non-transitory computer readable storage medium of claim 14, further comprising:

instructions to receive an indication to deactivate the privacy lens; and instructions to deactivate the UV LED to stop UV light from being emitted through the light guide to the privacy lens of a camera, wherein the organic photochromic material on the privacy lens is to turn transparent to allow the camera to capture images.
