Packaged information systems

A package indicator comprising:

• at least one LED comprising multiple semiconductor dies capable of emitting at least first light having a first spectrum and second light having a second spectrum, the first spectrum being different than the second spectrum, the first light and the second light being independently controllable such that at least three different colors may be generated by the at least one LED;
• a controller for generating and communicating control signals to the at least one LED wherein the controller is associated with a program input for receiving signals indicative of a condition of a package;
• and
• at least one of a sensor, transducer, timer, receiver, signal generator, wherein the at least one of a sensor, transducer, timer, receiver, signal generator communicates the signals to the program input, wherein the at least three different colors generated by the at least one LED relate to the condition of the package.

A system for indicating a condition of an item, comprising:

• an illumination system for providing illumination suitable for conveying information and capable of receiving input from an information system, the illumination system comprising (i) a first LED adapted to produce first light having a first spectrum, and (ii) a second LED adapted to produce second light having a second spectrum, the first spectrum being different than the second spectrum, and the first LED and second LED being arranged to permit combining of the first light and the second light;
• and
• the information system for providing input to the illumination system;
• wherein the information system provides information about the item and the illumination system is controlled to provide at least three different colors of illumination that indicate the information.
