Wearable lighting device

摘要

A user wearable device may be implemented with a light source to provide illumination to an area of interest. In one example, the light source may be selectively operated by switches, physical displacement (e.g., movement) of the device, or other approaches. In another example, the device may be implemented as a wristwatch to display time, date, or related information to a user. In another example, the device may be implemented with appropriate processing or communication components to perform other tasks. In other embodiments, various methods of using, operating, or manufacturing such devices are provided.

主权项

1. A device wearable on a wrist of a user, the device comprising:
a wrist strap; a housing connected to the wrist strap and substantially confined to the wrist while the wrist strap is worn by the user; a light source disposed substantially within the housing; a lens, separate from the light source, that receives light emitted by the light source and projects the light from an aperture in a front face of the housing to illuminate an area external to the device; wherein the lens is fixed relative to the front face of the housing, fixed relative to a bottom surface of the housing, and inclined to project the light with a maximum beam spread of approximately 60 degrees substantially centered about an axis at a fixed non-adjustable angle of approximately 35 degrees relative to the bottom surface of the housing, wherein the lens defines the maximum beam spread; wherein the fixed angle causes an edge of the maximum beam spread to be offset approximately 5 degrees relative to the bottom surface of the housing to prevent the projected light from overlapping onto a hand of the user associated with the wrist while the hand supports a firearm in a drawn position; and wherein the bottom surface of the housing is configured to be aligned on a top surface of the wrist while the user's palm is directed downwards and while the wrist strap is worn by the user.
