Abstract

A lighting system and method and apparatus for adjusting same are described. The lighting system has LED lighting units. To adjust a lighting unit, a programmer is connected to the lighting unit, lighting information (such as color or brightness) is input into the programmer (either manually or electronically), and data representing the lighting information is transmitted from the programming device to the lighting unit. The data is stored in the lighting unit, and one or more of the LEDs emits light that corresponds to the transmitted data.

Claims

1. A method for adjusting an LED lighting unit, the lighting unit comprising a plurality of LEDs, the method comprising:

connecting a programmer to the lighting unit;

inputting lighting information into the programmer;

transmitting data representing the lighting information from the programming device to the lighting unit; and

storing the data in the lighting unit, wherein one or more of the plurality of LEDs emit light that corresponds to the transmitted data.

2. The method of claim 1, wherein the color of the one or more of the plurality of LEDs changes after completion of the storing step, the method further comprising

observing the light being emitted by the one or more of the plurality of LEDs;

determining that the light being emitted by the one or more of the plurality of LEDs is not the correct color; and

based on the determining step, inputting new lighting information into the programmer.

3. The method of claim 1, further comprising:

comparing the color being emitted by the lighting unit to one or more other lighting units; and

based on the comparing step, determining what information is to be input during the inputting step.

4. The method of claim 1 wherein the information comprises color information.

5. The method of claim 1 wherein the lighting unit contains a microprocessor that transmits to the plurality of LEDs a signal representative of the data received from the programmer.

6. The method of claim 1 wherein the information comprises brightness information.

7. The method of claim 1 further comprising activating a user input mechanism that triggers the storing of the data in the lighting unit.

8. The method of claim 1, wherein the lighting unit is a first lighting unit, and wherein the inputting step comprises connecting the programmer to a second lighting unit, and transferring the lighting information from the second lighting unit to the first lighting unit.

9. The method of claim 1, wherein the inputting step comprises inputting color information and inputting brightness information.

10. An apparatus for adjusting an LED lighting unit, the apparatus comprising:

an input mechanism that receives lighting information, the lighting information representing a characteristic of the light that is supposed to be emitted from the LED lighting unit;

a memory that stores the received lighting information;

a feedback mechanism that shows the user what lighting information has been received from the user;

an interface that connects to the LED lighting unit; and

a controller that processes the received lighting information, retrieves the lighting information from the memory, and transmits the information to the LED lighting unit via the interface.

11. The apparatus of claim 10 wherein the input mechanism is comprised of a plurality of controls, each control being associated with a different color of LED of the lighting unit.

12. The apparatus of claim 10 wherein the input mechanism is selected from the group consisting of buttons, switches, levers, dials, and knobs.

13. The apparatus of claim 10, wherein the LED lighting unit is a first lighting unit, wherein the input mechanism is an interface that connects to a second LED lighting unit, wherein the controller executes software for performing the step of, downloading the lighting information from the second LED lighting unit.

14. The apparatus of claim 10, wherein the lighting information is information regarding the color of LEDs in the lighting unit.

15. The apparatus of claim 10, further comprising a mechanism that indicates whether the lighting information has been stored.

16. The apparatus of claim 10, wherein lighting information is information regarding the color and brightness of LEDs of the lighting unit.

17. The apparatus of claim 16, wherein the color and brightness information is for LEDs of at least three different colors.

18. The apparatus of claim 10, wherein the apparatus is a portable hand held unit.

19. A lighting system comprising:

a programmer further comprising;

a user input mechanism that receives color and brightness information from a user;

a communications interface; and

a microcontroller that transmits the color and brightness information via the communications interface;

a lighting unit coupled to the programmer, the lighting unit comprising;

a communications interface;

a microcontroller that receives the color and brightness information via the communications interface of the lighting unit and transmits a pulse width modulated signal representative of the color and brightness information;

one or more light emitting diodes that receive the pulse width modulated signal and emit light in response thereto; and

a memory for storing the color and brightness information.

20. The system of claim 19, further comprising a feedback mechanism that indicates to the user whether the color and brightness information has been transmitted from the programmer to the lighting unit.
