Controlled stratified random area illuminator
First Claim
1. A random area illuminator comprising:
- a base including a plurality of conductive layers and a plurality of insulating layers, said conductive and insulating layers being arranged in alternating layers,a plurality of illuminating means adapted to be mounted on said base in an illuminating array,each of said illuminating means having a light source and a post having said light source at one end thereof,each of said posts comprising first and second insulated electrical leads for supplying electric current to said light source mounted thereon,each of said posts being adapted to extend from the outer layer of said base to a common conductive layer of said base,said first lead of each post having an electrical contact arranged to provide electrical connection to said common conductive layer,said second lead of each post having an electrical contact arranged to provide electrical connection to another one of said conductive layers, andcontrol means for supplying electric current to selected ones of said other conductive layers.

Abstract
A controlled stratified random area illuminator is constructed of a base comprised of alternate layers of conductive and insulating material and a plurality of illuminating devices adapted to be positioned in a predetermined array on the base to provide an illuminating display. Each illuminating device comprises a light source and a post which carries a pair of leads for supplying current to the light source, one lead being adapted to make electrical contact with a common layer of conductive material and another lead which is adapted to make electrical contact with one of the other conductive layers. The illuminating devices and the base are constructed so that the illuminating devices can be installed by pushing them into the base material to penetrate the conductive and insulating layers to a predetermined depth. A selective switch controls the supply of electrical current to the conductive layers for illuminating a predetermined array of illuminating devices.
