Appl. No.:

09/682798

Inventors:

Eric Becks - Cheboygan MI, US
Thomas Gauthier - Cheboygan MI, US
Donald Russell - Lebanon IN, US

International Classification:

F21V007/04

US Classification:

362/555000

Abstract:

A trouble light apparatus constructed in accordance with the principles of the present invention employs high output Light Emitting Diodes to provide improved service over existing trouble lights by having extremely long life lighting elements, being extremely resistant to impacts and shocks that easily damage incandescent and fluorescent lamps, uses low power and does not generate hazardous levels of heat. The invention also anticipates other fabrication methods and the use of various spectra of LEDs to cause diagnostic markers to fluoresce.

Appl. No.:

7/431535

Inventors:

Donald C. McKinnon - Cheboygan MI

Assignee:

Ferret Instruments, Inc. - Cheboygan MI

International Classification:

F21V 712

US Classification:

362299

Abstract:

The invention pertains to a stroboscopic timing light for use with internal combustion engines. The reflector assembly is designed to increase the proportion of light from a flash tube that becomes part of a focused light beam. The reflector assembly comprises a pair of angled reflectors or series of reflectors forming a frusto-pyramid-like structure which reflects an array of images of a flash lamp. These images reflect the substantial portion of the light from the flash lamp while providing a cost effective and relatively inexpensive reflector assembly.
