Abstract
Wearable light device for providing additional light for activities in low light includes a wearable mount (20) including a light system (30) and power source (40). Light system (30) includes one or more arrays of light sources such as light-emitting diodes (33). Photo sensor (34) detects ambient light or emitted light returned from a reflective surface and causes control circuit (45) to dim light emission.
Claims21
A wearable light device;
- including:
- a mount adapted for being worn on the body;
- a light system;
- including:
- a circuit board;
- a plurality of visible light sources attached to said circuit board for emitting light generally parallel with the wearer's direction of gaze;
- and
- a light sensor attached to said circuit board for sensing light approaching said sensor;
- a power source for energizing said light sources, said light sensor, including:
- a battery;
- a housing for said battery;
- and
- a cable connecting said battery and said light system for transmitting electrical energy to said light system;
- and
- a control circuit for decreasing the intensity of light emitted from said light sources in proportion to the intensity of light striking said sensor.

A wearable light device;
- including:
- a mount adapted for being worn on the body;
- a light system;
- including:
- a circuit board;
- a first array of light sources attached to said circuit board for emitting light of a first color generally parallel with the wearer's direction of gaze;
- a second array of light sources attached to said circuit board for emitting light of a second color;
- and
- a light sensor attached to said circuit board for sensing light approaching said sensor;
- a power source for energizing said light sources;
- including:
- a source of electricity;
- and
- a cable connecting said source of electricity and said light system for transmitting electrical energy to said light system;
- and
- a control circuit for decreasing the intensity of light emitted from said light sources in proportion to the intensity of light striking said sensor;
- and wherein:
- said light sensor is shielded from sensing light directly emitted from said light sources of said light system.
15 more elements
A light device wearable on a human body, the light device comprising:
- a mount configured to be worn on the human body;
- a plurality of visible light sources disposed on the mount for emitting light generally parallel with the wearer's direction of gaze;
- and
- a light sensor disposed on the mount, wherein light emitted by the plurality of visible light sources is adjusted in response to an intensity of light incident on the light sensor.
