Abstract

This document describes a automatic lighting device that provides temporary illumination to assist an individual in locating a light switch or other source of light during low light conditions. This design incorporates improved performance, features, and functionality over previously published designs. The design shown here consists of a battery powered device housed by a plastic enclosure (1) approximately equivalent in size to a pack of cigarettes, and a permanent magnet (2). The device (1) is intended to be mounted above a doorway while the permanent magnet (2) is intended to be mounted to a door. The significant elements within the device (1) are batteries (3), one or more light emitting diodes (LED) (4), a magnetic field detecting element (5), a light detecting element (6), and a programmable microcontroller integrated circuit (MCU-IC) (7). Some of the primary design goals of this device are flexibility of placement, low maintenance, long battery life, and ease of use.
