20100214766 | HEADLAMP LIGHTING DEVICE - Various lighting devices are provided which may be used to advantageously illuminate areas of interest in a secure, convenient manner. In one example, a lighting device includes a headlamp. The headlamp includes a base, a body, and a light source. The base includes two support members and an aperture in each of the support members. The body is secured to the base through the apertures and is adapted to rotate relative to the base. The light source is in the body and positioned substantially between the two support members. The light source is adapted to rotate with the body relative to the base to adjust an angle of light emitted by the light source. As another example, related methods are also provided. | 08-26-2010 |
20100277295 | LIGHTING DEVICE WITH SELECTABLE OUTPUT LEVEL SWITCHING - Various techniques are provided for implementing a lighting device with selectable output level switching. In one example, a lighting device includes a light source, a controller adapted to provide one or more signals to control the operation of the light source, a power terminal adapted to receive a power source, and a tailcap assembly. The tailcap assembly includes a tailcap, a push button, and a washer disposed in the tailcap. The washer includes at least one arm adapted to be pushed against a surface to selectively connect the controller to the power terminal in response to a manipulation of the tailcap assembly. | 11-04-2010 |
20110169419 | PORTABLE LIGHTING SYSTEM - Various techniques are provided to facilitate the indication of visual signals, such as SOS signals, strobe signals, and/or types of signals using a portable lighting system. The system may be implemented as a flashlight, a headlamp, or other type of lighting system. The system may be operated using a push-button switch, a rotatable potentiometer, or other appropriate types of user control interfaces. In one example, the system includes a light source adapted to emit light. The system also includes a user control interface adapted to receive user input and generate one or more control signals based on the user input. The system further includes a control circuit adapted to receive the one or more control signals from the user control interface, determine a function sequence based on a pattern provided by the one or more control signals, and cause the light source to operate in accordance with the function sequence. | 07-14-2011 |
20120068624 | LIGHTING DEVICE WITH MULTI-POSITION JOYSTICK - Various lighting devices and related methods are provided. In one example, a portable lighting device includes a light source, lighting control circuitry, a body, and a tailcap assembly attached to an end of the body. The tailcap assembly includes a multi-position joystick adapted to pivot relative to the body in response to lateral pressure and move vertically relative to the body in response to vertical pressure. The tailcap assembly also includes switches adapted to provide signals to the lighting control circuitry in response to pivot movement and vertical movement of the joystick. The lighting control circuitry is adapted to operate the light source in response to the signals. | 03-22-2012 |
20120068625 | LIGHTING DEVICE WITH MULTIPLE ELECTRICAL CONNECTIONS - Various lighting devices and related methods are provided. In one example, a portable lighting device includes a light source, lighting control circuitry, first and second power terminals adapted to receive a battery power source, first and second electrical connections between the lighting control circuitry and the first and second power terminals, a third electrical connection between the second power terminal and the lighting control circuitry, and a switch adapted to selectively connect and disconnect the third electrical connection. The lighting control circuitry is adapted to operate the light source in response to a signal received over the third electrical connection in response to the switch. The first and second electrical connections are adapted to provide constant power to the lighting control circuitry while the battery power source is connected to the first and second power terminals regardless of operation of the switch. | 03-22-2012 |
20130043795 | LIGHTING DEVICE CONTROLLER PROGRAMMING - Various techniques are provided for programming lighting devices. In one example, a lighting device includes a light emitting diode (LED). The lighting device also includes a microcontroller configured to receive a programming signal generated by the LED in response to illumination of the LED with an externally-supplied light signal modulated with the programming signal. | 02-21-2013 |
20130043807 | LIGHTING DEVICE CONTROL USING VARIABLE INDUCTOR - Various techniques are provided for implementing a lighting device variable control using a variable inductor. In various examples, the variable control may be implemented with a plurality of continuous or stepped settings. The variable control may be adjusted by a user-actuated movement of a part of the lighting device, such as the depression of a tail cap or another appropriate physical control to change the inductance of the variable inductor. An oscillating signal may be induced in a variable inductor circuit that includes the variable inductor. The oscillating signal may exhibit characteristics, such as frequency, that change with the inductance of the variable inductor. Such characteristics may be measured to determine a setting of the variable control and which may be used to adjust the brightness or other attributes of the lighting device. | 02-21-2013 |
20150102746 | LIGHTING DEVICE CONTROL USING VARIABLE INDUCTOR - Various techniques are provided for implementing a variable control for a lighting device, such as a flashlight, that uses a variable inductor. The lighting device may include a tail cap, a battery terminal, and a variable inductor mounted in the tail cap and electrically connected in series with the battery terminal. The lighting device may also include a user operable switch configured to selectively bypass the variable inductor. The variable inductor may include, for example, a magnetic coil comprising a wire coil and a core. The variable inductor may also include a ring comprised of ferrous material and having a substantially elliptical inner circumfery and surrounding the magnetic coil, wherein the ring is adapted to be rotated relative to the magnetic coil in response to user actuation of a rotatable user control. | 04-16-2015 |
