Patent number: 7293898Abstract: A portable personal headlamp utilizes an array of light-emitting diodes on the front face of a circuit board. Arc-shaped projections on the front face of a finned heat sink are in heat-conducting relationship with printed conductors on the rear face of the circuit board, which partially surround one lead of each light-emitting diode.Type: GrantFiled: July 29, 2005Date of Patent: November 13, 2007Assignee: Princeton Tectonics, Inc.Inventors: Yos Kumthampinij, Kenneth Zorovich, Walter Andrew

Patent number: 7125139Abstract: In auxiliary headlamp, for attachment to the headstrap of a personal headlamp, a lamp body is removably attachable to a strap bracket having a strap-receiving slot through which a headstrap can extend. When the lamp body is attached to the strap bracket, the lamp body is rotatable about an axis of rotation which extends in perpendicular relationship to the portion of the headstrap held in the slot, and the lamp is arranged to project a beam of light in substantially perpendicular relationship to the axis of rotation of about which the lamp body is rotatable.Type: GrantFiled: February 25, 2005Date of Patent: October 24, 2006Assignee: Princeton Tectonics, Inc.Inventors: Yos Kumthampinij, Kenneth Zorovich

Patent number: 7048407Abstract: A miniature LED flashlight is composed of a flashlight assembly and an attachment loop. The attachment loop is configured to require a two-step manipulation for attachment or detachment from a key ring. The flashlight assembly and attachment loop are attached by a snap fit relationship between a projection on one and a recess on the other, and can be readily disconnected by application of a bending force.Type: GrantFiled: October 6, 2003Date of Patent: May 23, 2006Assignee: Princeton Tectonics, Inc.Inventors: Yos Kumthampinij, Kenneth Zorovich

Patent number: 6220720Abstract: A rotatable head flashlight utilizes a bulb carrier having a circuit board on which are mounted contacts which remain in engagement with energy cells in a battery compartment, a bulb-receiving socket, and a switch assembly engageable with, and operated by, a molded shelf on the inner wall of the battery compartment. The switch includes three contacts, one being a movable contact in the form of a resilient, bridge-like element overlying both of the other contacts, the latter two contacts being printed on the circuit board.Type: GrantFiled: July 16, 1999Date of Patent: April 24, 2001Assignee: Princeton Tectonics, Inc.Inventor: Jeffrey C. Stephens

Patent number: 4458299Abstract: The magnetic switch is a plastic unit which is made up of a housing containing three pieces, a slideable magnet holder, a bracket, and a plastic leaf spring. The magnet holder and the bracket include keys and notches to provide positive "on" and "off" positions. The housing is aligned with a mercury wetted switch which is capable of handling large current surges without being damaged, whereby the magnet holder is depressed against the spring bias and slid into either the "on" or the "off" position.A hermetically sealed flashlight which includes the magnetic switch is also described. The flashlight comprises a case which is houses dry cells. A screw-on cap which includes a lens forms a hermetic seal when an O-ring is compressed as the cap is engaged.A reflector mount is aligned with the case using a notch and key system which insures the alignment of the mercury wetted magnetic switch and the housing for the magnet holder.Type: GrantFiled: October 26, 1981Date of Patent: July 3, 1984Assignee: Princeton TectonicsInventors: Arthur W. Stephens, John J. Penrose
