Light lens assembly for wearable electronic device
A wrist-wearable electronic device comprising a house, a display, and a lens module. The lens module is coupled to a sidewall of the housing and can include a first light emitting element, a lens, and a first Frensel structure. The lens includes a body, a lower surface, and an upper surface. The first Frensel structure is disposed on the lower surface of the lens and is configured to disperse light generated by the first light emitting element into the body of the lens.
1. A wrist-wearable electronic device comprising:
a housing including a face and a sidewall;
a display supported by the face of the housing; and
a lens module coupled to a sidewall of the housing, the lens module including:
a first light emitting element,
a lens positioned above the first light emitting element, the lens including a body, a lower surface, and an upper surface, wherein the lower surface is directed toward the first light emitting element,
a first Fresnel structure disposed on the lower surface of the lens, the first Fresnel structure configured to disperse light generated by the first light emitting element into the body of the lens, and
a second Fresnel structure disposed on the upper surface of the lens, the second Fresnel structure configured to focus light exiting the body of the lens.
2. The device of claim 1 , further including a plurality of light emitting elements, wherein the first Fresnel structure is configured to disperse light generated by the plurality of the light emitting elements into the body of the lens.
3. The device of claim 1 , wherein the first Fresnel structure is a linear Fresnel structure.
4. The device of claim 1 , wherein the lens modules is coupled to the sidewall of the housing between a 10:00 and a 2:00 position on the housing.
5. The device of claim 1 , wherein the display includes a touch screen configured to receive a user input from a user.
6. The device of claim 1 , wherein the lower surface of the body includes an arcuate center portion positioned between descending protrusions, the first Fresnel lens being disposed on the arcuate center portion and at least a part of the descending protrusions.
7. A wrist-wearable electronic device comprising:
a housing including a face and a sidewall;
a display supported by the face of the housing; and
a lens module coupled to a sidewall of the housing between a 10:00 and a 2:00 position on the housing, the lens module including:
a plurality of light emitting elements,
a lens positioned above the light emitting elements, the lens including a body, a lower surface having an arcuate portion, and an upper surface, wherein the lower surface is directed toward the first light emitting element, and
a linear Fresnel structure disposed on the lower surface of the lens, the linear Fresnel structure configured to disperse light generated by the first light emitting element into the body of the lens, the linear Fresnel structure including a plurality of parallel grooves.
8. The device of claim 7 , further including a circular Fresnel structure disposed on the upper surface of the lens, the circular Fresnel structure configured to focus light exiting the body of the lens.
9. The device of claim 8 , where in the circular Fresnel structure occupies only a portion of the upper surface of the lens, wherein a first one of the light emitting elements is positioned such that light passing from the first light emitting element through the lens body substantially exits through the circular Fresnel structure.
10. The device of claim 8 , wherein the upper surface of the lens includes a haze to diffuse light exiting the lens body.
