Abstract

Disclosed herein are embodiments of a LED fluorescent tube replacement lamp and lighting modules from which the lamp is constructed. One embodiment of a replacement lamp includes a plurality of interchangeable lighting modules that are configured to be electrically connected to adjacent modules. The interchangeable lighting modules can include end modules each having an end cap with pin connectors, at least one of the end modules includes electrical circuitry connected to the pin connectors for powering the modules. The lighting modules can also be center unit modules having LEDs mounted to a circuit board. The replacement lamps can be made from conceivable configurations of the lighting modules, requiring removal of only one module for repair or replacement.

Claims (39)

1. A LED fluorescent tube replacement lamp comprising:

a plurality of interchangeable lighting modules, wherein adjacent modules are electrically connected, the plurality of interchangeable lighting modules including:

two end modules each including an end cap with at least one end connector, at least one of the end modules including electrical circuitry connected to the at least one end connector for powering the end modules; and

at least one center module including electrical circuitry; and

wherein any one of the two end modules and the at least one center module is manually separable from an adjacent module and replaceable with a like module.

2. The lamp of claim 1 further comprising:

at least one another connector providing an electrical connection to the at least one center module.

3. The lamp of claim 1 wherein:

the at least one end connector on at least one of the end caps includes two connectors.

4. The lamp of claim 2 further comprising:

the electrical circuitry in the at least one center module includes a circuit board with at least one electrically connected LED; and

the at least another connector electrically connects the at least one end cap to the circuit board in the at least one center module.

5. The lamp of claim 1 wherein:

the two end modules and the at least one center module are replaceably electrically connected.

6. The lamp of claim 1 further comprising:

a bridge connector, wherein the bridge connector electrically connects adjacent of the two end modules and the at least one center module and mechanically couples the adjacent of the two end modules and the at least one center module in a manually separable connection.

7. The lamp of claim 1 wherein:

the electrical circuitry in at least one of the end modules includes a power converter.

8. The lamp of claim 1 further comprising:

a housing coupled between the two end modules and encompassing the at least one center module.

9. An interchangeable end module for an LED fluorescent tube replacement lamp connectable to another interchangeable lighting module, comprising:

a housing, an end cap mounted in one end of the housing and having at least one end connector, and electrical circuitry connected to the at least one end connector for powering the LED fluorescent tube replacement lamp;

wherein the end module is connectable to a center module, the end module and the center module configured to be coaxially arranged with adjacent ends of the end module and the center module joined into a unitary housing; and

wherein the end module is replaceable with a like module.

10. The end module of claim 9 , wherein the center module includes a housing encompassing a circuit board and at least one LED mounted on the circuit board.

11. The end module of claim 9 , wherein the center module includes bridge connectors coupled to opposing ends of the circuit board for separable connection to adjacent light modules.

12. The end module of claim 9 , wherein the end module and the center module are replaceably electrically connected.

13. The end module of claim 9 , wherein the electrical circuitry in the end module includes a power converter.

14. The end module of claim 9 , wherein the unitary housing is one of a translucent and transparent, cylindrical housing.

15. An interchangeable center module for an LED fluorescent tube replacement lamp connectable to another interchangeable lighting module, comprising:

a housing encompassing a circuit board and at least one LED mounted on the circuit board;

wherein the center module is connectable to an end module, the center module and the end module configured to be coaxially arranged with adjacent ends of the center module and the end module joined into a unitary housing; and

wherein the center module is replaceable with a like module.

16. The center module of claim 15 , further comprising:

bridge connectors coupled to opposing ends of the circuit board for separable connection to adjacent light modules.

17. The center module of claim 15 , wherein the end module and the center module are replaceably electrically connected.

18. The center module of claim 15 , wherein the electrical circuitry in the end module includes a power converter.

19. The center module of claim 15 , wherein the like module contains an LED that is of a different type than the at least one LED.

20. The center module of claim 9 , wherein the unitary housing is one of a translucent and transparent and a cylindrical housing.
