  • Publication number: 20200030053
    Abstract: A lamp having a front surface from which light is emitted and that includes a high efficiency light source assembly producing a beam having a 3 dB beamwidth of greater than 100°, and which includes a substrate, a high efficiency light source supported by the substrate; and a dome-lens that contains the high efficiency light source. Also, an optical assembly is positioned to receive light from the light emitting diode assembly and to produce a headlamp light beam emitted from the front surface of the lamp. Further, an annular light block defines an annulus and is placed about the lens, so that the lens protrudes through the annulus, thereby creating a sharp boundary for the output light beam.

  • Patent number: 10258411
    Abstract: A video headband assembly, having a headband structure, made at least in part of polymeric material, a battery port, a power management network having at least one output lead, and which supplies power from the battery port to the output lead and a multi-pin connector, accessible from outside the headband structure. Also, a video data signal transformation network is supported within the polymeric material of the headband structure and electrically connected to the multi-pin connector. Finally, a first video data signal input to the multi-pin connector is transformed by the video data signal transformation network, which produces a transformed video data signal in response to the first video data signal.

  • Publication number: 20190093862
    Abstract: A medical headlamp, having a tubular housing, an electrical conductor, entering the housing, and an electrical network connected to the electrical conductor. An LED assembly is connected to the electrical network, and has a front surface, through which light is emitted. An iris assembly, including a toroidal housing, an iris diaphragm defining a width-adjustable aperture, seated in the housing, and an actuator, permitting a user to adjust the width of the width adjustable aperture. Further, the toroidal housing defines a front interior space, to the front of the iris diaphragm and a rear interior space, to the rear. A prime lens is placed in front of the iris diaphragm and has a rear surface. A further optical assembly, including at least a light-focusing lens is placed in front of the iris assembly. Finally, the prime lens rear surface has an opaque annular coating, acting as an annular light block.

  • Patent number: 10174912
    Abstract: A medical headlamp that includes a tubular housing an electrical network electrically connected to an electrical conductor, a bare LED assembly electrically connected to the electrical network, an annular light block defining an aperture placed in front of the LED, and an optical assembly including at least a light focusing lens placed in front of the annular light block. A central beam of light from the LED passes through the aperture, and peripheral light from the LED is blocked by the light block such that the central light beam is focused by the optical assembly to create a beam of light having sharp edges.

  • Patent number: 9707707
    Abstract: A battery headlamp assembly that includes a light engine bezel, an adjustable linkage supporting the bezel and including an electrically conductive system terminating at the bezel. Also, a headband assembly supports the adjustable linkage and includes a longitudinal rigid-flex circuit assembly. This assembly has a strip of rigid-flex circuit having two longitudinally opposed ends and including battery contacts on the ends. Also, two networks of electrical components are each supported by and electrically connected together, and to one of the battery contacts, by the strip of rigid-flex circuit, which includes conductive traces connecting both the networks to the electrically conductive system and to each other, to power the bezel from the battery contacts and to permit communications between the networks. In addition, a further electrically conductive element, electrically connects at least one conductive trace of the rigid-flex circuit to the electrically conductive system of the adjustable linkage.

  • Publication number: 20160123563
    Abstract: A medical headlamp having a front from which light is selectively emitted. The headlamp includes a beam origination portion that produces a light beam and an iris assembly, positioned in front of the beam origination portion, having a user accessible actuator and an iris, responsive to the actuator to block a user selectable portion of the light beam. The iris is also responsive to the actuator to block none of the light beam, for maximum efficiency, when a user so selects.
