Abstract

Aspects of the instant disclosure relate to electronic cigarettes. More particularly, to electronic cigarettes including a circumferential light guide that distributes light transmitted by a light source, and controller circuitry that variably illuminates the circumferential light guide of the electronic cigarette based on a user's draw strength.

First claim

What is claimed is:

1. A electronic cigarette tip diffuser comprising:
a bi-convex lens; and
a plurality of light diffusing features extending into a proximal surface of the tip diffuser.

2. The electronic cigarette tip diffuser of claim 1 , wherein the plurality of diffusing features are pyramidal apertures.

3. The electronic cigarette tip diffuser of claim 1 , wherein the plurality of diffusing features are evenly distributed across the proximal surface of the tip diffuser.

4. The electronic cigarette tip diffuser of claim 1 , wherein the plurality of diffusing features are unevenly distributed across the proximal surface of the tip diffuser.

5. The electronic cigarette tip diffuser of claim 1 , wherein the electronic cigarette tip diffuser is configured and arranged to diffuse light received from a single point source to produce even illumination along a distal surface of the tip diffuser.

6. The electronic cigarette tip diffuser of claim 1 , wherein the plurality of light diffusing features form a pattern.

7. The electronic cigarette tip diffuser of claim 1 , wherein the plurality of light diffusing features further include secondary light diffusing features selected from the group consisting of: surface texturing, and material characteristics or additives to the tip diffuser that facilitate internal light diffusion.

8. The electronic cigarette tip diffuser of claim 1 , wherein the bi-convex lens includes side-walls configured and arranged to further facilitate diffusion of light through the tip diffuser.

9. The electronic cigarette tip diffuser of claim 8 , wherein the side-walls are selected from the group consisting of: sloped, straight, or rounded.

10. The electronic cigarette tip diffuser of claim 1 , further including a second plurality of light diffusing features extending into a distal surface of the tip diffuser.

11. The electronic cigarette tip diffuser of claim 1 , wherein a distal surface convex lens of the bi-convex lens is configured and arranged to distribute the light across a wide viewing angle.

12. An electronic cigarette comprising:
a tip diffuser; and
wherein the tip diffuser is a bi-convex lens with a plurality of diffusing features extending into a proximal surface of the tip diffuser.

13. The electronic cigarette of claim 12 , wherein the plurality of diffusing features are pyramidal apertures and are evenly distributed across the proximal surface of the tip diffuser.
