  • Publication number: 20140334157
    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.

  • Publication number: 20140334132
    Abstract: A lamp having a front surface from which a beam of light is emitted and that includes a housing. An optical assembly is supported and partially enclosed by the housing, and includes an LED assembly, a prime lens and an exit lens, with light emitted from the LED assembly passing through the aspheric prime lens and exiting through the exit lens. Also, the exit lens defines a front surface and a rear surface and the rear surface has a convex shape different from the shape of the front surface.

  • Publication number: 20140334159
    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 AE, 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.

  • Publication number: 20140336472
    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.
