Patent number: 9416937Abstract: The present disclosure relates to a thin-profile lens for shaping a beam of light from a light source, such as a light emitting diode (LED), for example in a flashlight or other lighting unit. In various embodiments, the lens may be combined with an adjustment mechanism for varying the focus of the beam of light, and may be housed in a structure supporting the lens, light source, and adjustment mechanism. In various embodiments, the structure also may include a power source, controls, interconnections, and electronics. In various embodiments, the thin profile of the lens may allow the lens to be used in any of a number of applications, ranging from narrow diameter flashlights to large diameter light sources.Type: GrantFiled: June 6, 2012Date of Patent: August 16, 2016Assignee: Coast Cutlery Co.Inventors: Gregory David Windom, David C. Brands

Patent number: 8152327Abstract: A lens for a flashlight or other lighting unit provides for focusing light from a source, such as an LED, to provide a light beam adjustable between a spot beam and a wide beam. The lens includes a lens body with a front face, a rear LED-receiving well, and a side surface extending between the front face and the rear well. The front face includes a central surface surrounded by an annular concave surface. The rear well includes a space for the LED to be adjusted in position. The rear well space is defined by a concavely-curved sidewall and a concavely-curved base. The concave curvature of the sidewall and base may be Bezier curves.Type: GrantFiled: October 2, 2009Date of Patent: April 10, 2012Assignee: Coast Cutlery CompanyInventors: David C. Brands, R. Stephen Mulder, David Lewin

Publication number: 20080074885Abstract: A lighting unit is provided including at least one LED, a plug for connecting the unit to an appliance and a light emitting element. The lighting unit may include electronic components to condition power from the appliance. The light emitting element may comprise a reflector where the LED emits light into the reflector and the light is collimated by the reflector and emitted from the unit. The position of the LED may be adjustable so the LED moves closer or farther from the reflector. Light is emitted from the unit in a narrower or wider beam in response to moving the LED. Alternately, the light emitting element may be an optical waveguide with a receiving end proximate to the LED emitting face and an emitting face away from and opposite the receiving face. The optical waveguide may collimate the wide angle of light emitted by the LED to form a narrow, directed beam.Type: ApplicationFiled: August 31, 2006Publication date: March 27, 2008Inventors: David C. Brands, Richar Yee, Rainer Opolka
