  • Patent number: 9693425
    Abstract: A wearable headlamp is provided that may provide improved illumination control and adjustability. The wearable headlamp may include a primary light-emitting diode (LED) configured to illuminate an area in front of the headlamp and a photosensor configured to detect the level of ambient light surrounding the headlamp and adjust the luminous flux of the light emitted by the primary LED accordingly. Additionally, the headlamp may include an alternate, red LED to provide illumination where the brightness of the primary LED is not suitable. Furthermore, both the primary LED and alternate LED may be secured within a pivotable lamp housing that enables the direction of the light emitted from the LEDs to be adjusted.

  • Patent number: 9647473
    Abstract: Provided herein is an improved apparatus and system for providing a flashlight and charging base system. The flashlight of may include a light source, a power source having a charge level, a housing defining a major axis along which the housing extends, an adjustable ring disposed about the housing, where the adjustable ring is configured to be rotated between at least two positions, where each of the at least two positions define a different mode of operation, and a switch located proximate the barrel, where the switch is configured to turn the flashlight on and off. The adjustable ring may include a magnet, where the housing includes a Hall effect sensor, where the at least two positions of the adjustable ring are recognized by the position of the magnet relative to the Hall effect sensor.
