Abstract

A sculptable, decorative light system includes a number of modules of differing lengths which can respond to commands either in parallel or time delay to create pre-selected light colors and sequences. Three miniature connectors are used to create a direct current fed system which has the potential to even out a current demand. Interconnectable lamp modules are provided in sets of 1, 2, 3, 4, and more lengths to create decorative light displays. Each lamp module or string of modules may include a male/plug end and a female/receptacle end.

Claims

1. A lamp module comprising:

a housing support;

a voltage/current supply line, having an first end and a second end, and supported by said housing support;

a ground line having a first end and a second end and supported by said housing support;

a first control line supported by said housing support, having a first end and a second end;

a second control line supported by said housing support, having a first end and a second end;

a controller having a first connection to said second end of said first control line, at least one current switching input, and a second connection to said first end of said second control line output, and a power input connected to said voltage/current supply line, a ground connection connected to said ground line, said controller configured to control access of said current switching input to said ground line;

at least one light emitting diode having a current input connected to said voltage/current supply line and a current output connected to a corresponding current switching input of said controller.

2. The lamp module of claim 1 wherein said and further comprising a shunt line connecting said second end of said control line input and said first end of said control line output.

3. The lamp module of claim 1 and further comprising a capacitor between said voltage/current supply line and said ground line for helping to maintain a voltage of said voltage/current supply line during intermittent periods of current flow through said at least one light emitting diode and any other current user of said voltage/current supply line internal or external with respect to said lamp module.

4. The lamp module of claim 1 wherein said at least one light emitting diode is at least two light emitting diodes of different colors and wherein said controller is configured to control access of said current switching input to modulate the intensity of said at least two light emitting diodes to emit a controlled composite color.

5. The lamp module of claim 1 wherein said other lamp modules connected in series to each other includes branch connections to each other.

6. The lamp module of claim 1 wherein said controller having first connection to said second end of said control line and a second connection to said first end of said control line is configured to receive and re-transmit an counter signal indicative of the number of other lamp modules connected in series to each other and to said lamp module on at least one of said first and second connections.

7. The lamp module of claim 1 wherein said controller having first connection to said second end of said control line and a second connection to said first end of said control line is configured to assume control of the number of other lamp modules connected in series to each other and to said lamp module on at least one of said first and second connections in the absence of an external master controller, and control said other lamp modules connected to said lamp module on at least one of said first and second connections.

8. The lamp module of claim 7 wherein said assume control of a number of other lamp modules connected in series to each other and to said lamp module on at least one of directing said LED'"'"'s of said lamp module and other lamp modules to operate and shut down at scheduled times, control of selection and execution of different lighting patterns during different portions of the day for said LED'"'"'s of said lamp module and other lamp modules, control of a sequence pattern of for said LED—

s of said lamp module and other lamp modules so that they flash the patterns, and control a real time system status check system to report on the state of said LED—

s of said lamp module and other lamp modules.

9. The lamp module of claim 7 wherein said assume control of a number of other lamp modules connected in series to each other and to said lamp module on at least one of said first and second connections in the absence of an external master controller includes at least a first LED pattern which is communicated to said other lamp modules connected to said lamp module on at least one of said first and second connections.

10. The lamp module of claim 7 wherein said assume control of a number of other lamp modules connected in series to each other and to said lamp module on at least one of said first and second connections in the absence of an external master controller includes at least a synchronization signal which is communicated to said other lamp modules connected to said lamp module on at least one of said first and second connections.

11. The lamp module of claim 1 and further comprising a multiplicity of said lamp modules connected in series to each other and further comprising a master controller connected to one of multiplicity of said lamp modules which is connected to only one other of said multiplicity of lamp modules and wherein said master controller controls said multiplicity of said lamp modules.

12. The lamp module of claim 11 and further comprising a multiplicity of said lamp modules connected in series to each other and further comprising a power supply connected to any one of said multiplicity of said lamp modules.

13. The lamp module of claim 11 wherein said multiplicity of said lamp modules each has an address and wherein master controller is configured to receive said addresses and derive an pattern map of said multiplicity of said lamp modules.

14. The lamp module of claim 11 wherein said multiplicity of said lamp modules, master controller form a modular light system and further comprising:

a plurality of said modular light systems; and

,

a master system housing supporting said plurality of modular light systems; and

a power supply supported by said master system housing and connected to at least one of said plurality of said modular light systems.

15. The lamp module of claim 11 wherein at least two of said multiplicity of said lamp modules are connected with an interconnector cord

16. The lamp module of claim 1 wherein said housing support includes at least one of a male plug and a female plug.

17. The lamp module of claim 1 wherein said housing support includes at least one extended conductor set.

18. The lamp module of claim 1 wherein said housing support includes a light transmissive anisotropic material.
