Serially connecting OLED devices for area illumination
First Claim
1. An area illumination apparatus, comprising(a) a multiplicity of spaced-apart OLED devices electrically connected in series including a common substrate and each OLED device formed simultaneously over the common substrate;
- and(b) a power source connected to the first and last OLED devices of the series of spaced-apart OLED devices; and
further comprising a socket wherein the power source is connected through the socket to the area illuminating apparatus and wherein the common substrate is removably insertable into the socket.

Abstract
An area illumination apparatus, including a multiplicity of spaced-apart OLED devices electrically connected in series including a common substrate and each OLED device formed simultaneously over the common substrate; and a power source connected to the first and last OLED devices of the series of spaced-apart OLED devices. The series of OLED devices formed simultaneously on a common substrate can be manufactured in situ. Moreover, by serially connecting the OLED devices the application of power to the devices is simplified. A socket can be used to readily adapt the area illumination apparatus for use with the existing lighting infrastructure.
