View Patent ↗A lighting device or lighting associated device which includes an off-line computer in addition to the controlling computer. The off-line computer is one that uses less power, but is accessible wirelessly even when the light is off-line and not receiving power. The off-line computer can be used to update the program and/or media that is stored in the lighting device.
1. A computer-controlled lighting device, comprising:
a lighting device, producing a light output;
said lighting device including a lighting-controlling computer part, said lighting-controlling computer part controlling said light output, said lighting-controlling computer part communicating over a network and receiving signals over the network, said lighting device including a memory that stores a controlling program for the lighting device,
and said lighting-controlling computer part operating when said lighting device has external power applied thereto, said lighting-controlling computer part operating based on said external power for accessing a lighting program stored in said memory, and operating said lighting device based on said lighting program stored in said memory, and said lighting-controlling computer part not operating while said lighting device does not have said external power applied thereto;
an assisting computer part, operable when said lighting device does not have the external power applied thereto and the lighting-controlling computer part is not operating, said assisting computer part including a battery, and a wireless communicator, powered by said battery, wherein said assisting computer part is operated based on power from said battery and accesses said lighting program stored in said memory, and provides information about said lighting program over said wireless communicator when said lighting device does not have the external power applied thereto, said information about said lighting program including information about a program that will control operation of the lighting device, and information about a revision of software that operates said lighting device, both of said information about the program that will control operation of the lighting device, and said information about the revision of software that operates said lighting device are provided over said wireless communicator,
and where said lighting-controlling computer part does not operate from said power from said battery.
2. The device as in claim 1 , wherein said assisting computer part receives a software update during a time when said lighting device does not have said power applied thereto and the lighting-controlling computer part is not operating.
3. The device as in claim 1 , wherein said information about said lighting program includes information indicating specific items of non transitory computer readable media items that are stored in said lighting device.
4. The device as in claim 3 , wherein said assisting computer part receives other items of non transitory computer readable media items to be stored in said lighting device, said receives being during a time when said lighting device does not have power applied.
5. The device as in claim 3 , wherein said wireless communicator accepts messages only when a specified encryption criteria is met for said messages.
