Abstract: An illuminating module with battery backup consisting of an array of light-emitting diodes is provided wherein the module combines the battery backup with the LED array in a self-contained light bulb-like unit which can be retrofitted into an existing incandescent light bulb socket. The batteries and the LED array are attached to a planar baseboard which further includes two base connectors. The base connectors are adapted to fit into existing light bulb sockets and are rotatably mounted on an edge of the baseboard to enable screwing them into light bulb sockets while the baseboard is kept stationary. The backup batteries are recharged from an external source of electrical current flowing through the base connectors. An automatic switching device switches the supply of electrical power for the LED array from the external source of electrical power to the backup batteries, when the flow of external electrical power is disrupted.

Abstract: A panel illuminating module consisting of an array of light-emitting diodes is provided wherein the light from the array can be adjustably directed to a target after the module is installed within the panel. The module has two parts, an upper part carrying the light-emitting diodes, and a lower part which is designed to install into standard panel circuitry connectors. The upper part is attached to the lower part by a cylindrical shaft about which one of the two parts is rotatable. Spring tension normally holds the two parts together on the shaft and a locking pin normally prevents the two parts from rotating relative to one another. However, the two parts can be optionally pulled apart from one another (against the spring tension) to disengage the locking pin and to allow the two parts to rotate relative to one another.

Abstract: A removable panel-illuminating module is provided wherein the module comprises an array of light-emitting diodes. The module is quickly and easily installed and de-installed from standard panel circuitry connections without having to rotate the planar surface of the module.
