Title: Craig D. Raleigh and a Waterproof Light-Delivery System

Introduction

Craig D. Raleigh is an inventor associated with Saukville, Wisconsin. His work includes a patent for a waterproof system designed to deliver light to a light guide, with features intended to protect its components and support installation beneath the ground.

Latest Patents

Raleigh is credited with 1 patent: “Waterproof System for Delivering Light to a Light Guide.” The invention uses a light source and a hollow, generally tubular coupling device with an interior reflective surface. The coupling widens from its inlet to its outlet, helping reduce the angle of reflected light as it travels through the device.

A thermal-isolating region transfers light from the coupling device to an optical member. The light source and coupling device are housed in a waterproof container, with an aperture sealed in part by a member of the thermal-isolating region. The system is designed to be buried beneath the ground, helping prevent collisions with people or equipment and protecting enclosed components from wildlife, dirt, and dust. Some embodiments can operate without a fan, reducing system complexity and noise.

Career Highlights

Raleigh is associated with Fiberstars, Inc. His patent describes an approach to delivering light while isolating heat and protecting key components in a sealed enclosure.
