Optic Fiber Led Light Source

View page
US Patent:
7217022, May 15, 2007
Filed:
Aug 31, 2004
Appl. No.:
10/930283
Inventors:
Marvin Ruffin - Chicago IL, US
Assignee:
Opto Technology, Inc. - Wheeling IL
International Classification:
F21V 8/00
US Classification:
362554, 362555, 362582, 362581
Abstract:
An exterior lighting device based on a light emitting diode in conjunction with an optic fiber is disclosed. The device has a cylindrical housing having a closed end and an open end. The light emitting diode is placed on the interior of the on the closed end of the cylindrical housing. A clear lens having one end in proximity with the light emitting diode and an opposite end with a flat surface is provided. A top cap is installed over the open end of the cylindrical housing. The top cap forms a water tight seal with the cylindrical housing using O-rings. A retaining plate is held in place between the top cap and the cylindrical housing. The retaining plate is locked with the flat surface of the lens thus holding the lens in place over the light emitting diode. An optic fiber has a receiving end held by the retaining plate in proximity to the light emitting diode and an opposite emitting end extending from a socket in the top cap. A coupling assembly sits in the socket in the top cap and holds the optic fiber in relation to the top cap.

Quadrilateral Symmetrical Light Source

View page
US Patent:
7300185, Nov 27, 2007
Filed:
Jul 2, 2003
Appl. No.:
10/612612
Inventors:
Marvin Ruffin - Chicago IL, US
Craig Fields - Chicago IL, US
Assignee:
Opto Technology, Inc. - Wheeling IL
International Classification:
F21V 7/04
US Classification:
362347, 362334, 362335, 362349, 362346
Abstract:
A reflector for focusing light emitted from a light source in a generally planar direction is disclosed. The reflector is matched with the light source that is preferably a light emitting diode (LED) mounted on a substrate. The reflector is mounted over the LED on the substrate. The reflector is made of a clear material. The reflector has a semi-cylindrical front surface and a back surface with an indentation that is compatible with the light source. The reflector has a top reflecting surface divided into two quadrants and a bottom reflecting surface divided into two quadrants. The top quadrants and bottom quadrants are symmetrical in shape and reflect light emitted from the light source in a substantially horizontal plane. The reflecting surfaces may be TIR based or they may be coated with a reflective material in order to focus light from the LED.

Integrated Led Heat Sink

View page
US Patent:
7679096, Mar 16, 2010
Filed:
Aug 21, 2003
Appl. No.:
10/645474
Inventors:
Marvin Ruffin - Chicago IL, US
Assignee:
Opto Technology, Inc. - Wheeling IL
International Classification:
H01L 29/26
US Classification:
257 99, 257720
Abstract:
A heat sink for use with a high output LED light source is disclosed. The heat sink is used with an LED and conical reflector. The heat sink has a cylindrical back end holding the light emitting diode. The heat sink includes a conically shaped wall having an inner and outer surface and an open front end. The open front end has a rim with notches. The reflector has a front flat surface with arms which are fixed in the notches with a fastener. The heat sink includes a plurality of slits formed on the inner and outer surfaces extending between the back and front ends. A plurality of vanes extend radially from the inner surface. The heat sink is fabricated from a thermally conductive material. The conical shape of the heat sink, the slits and vanes increases exposed surface area to assist in dissipating heat generated from the LED.

Multiple Led Focused Lighting Device

View page
US Patent:
20050231974, Oct 20, 2005
Filed:
Apr 14, 2004
Appl. No.:
10/824277
Inventors:
Marvin Ruffin - Chicago IL, US
International Classification:
F21V007/04
US Classification:
362555000, 362551000
Abstract:
A multiple LED based lighting device for commercial indoor or outdoor architectural applications is disclosed. The lighting device uses multiple LEDs which are arranged in a symmetrical array in order to combine their light output. The LEDs are supported in a fixed position and have a conical reflector to assist in focusing the light output. A heat sink is attached to the LEDs to allow for use of high power for greater light output. The multiple LEDs are mounted relative to an optic fiber which has a core and cladding material to retain light based on total internal reflection. The light output from the LEDs are cast on the optic fiber which may provide side lighting effects from the perimeter of the optic fiber or emit light from the opposite end of the optic fiber.

System And Method For Manufacturing A System For Filtering And Disinfecting Drinking Water

View page
US Patent:
20220220004, Jul 14, 2022
Filed:
May 16, 2019
Appl. No.:
17/607225
Inventors:
- Mississauga, CA
Marvin Ruffin - Chicago IL, US
International Classification:
C02F 1/00
C02F 1/32
Abstract:
A water filter system includes a water filter assembly and an enclosure. The water filter assembly has a housing with a water inlet and a water outlet, a filter portion within the housing, and a reservoir portion within the housing apart from the filter portion. A window in the housing conveys ultraviolet light into the reservoir from an external light source. A water channel conveys water from the inlet to the outlet through the filter and the reservoir portions. The enclosure removably receives the water filter assembly in a cavity within the enclosure. An enclosure water inlet mates with the filter water inlet, and an enclosure water outlet mates with the filter water outlet. A light source within the enclosure is arranged to direct light into the reservoir portion.
