Abstract

A modular lighting system has lamps that may be connected to one another such that current is carried between the lamps. The lamps include an enclosure that is at least partially optically transmissive. At least one LED is located in the enclosure that is operable to emit light through the enclosure when energized through an electrical path. A first electrical connector is provided for connecting the electrical path to a power source and a second electrical connector is configured to connect the electrical path to a second lamp.

Claims

1. A lighting system comprising:

a lamp comprising;

an enclosure being at least partially optically transmissive;

at least one LED in the enclosure operable to emit light through the enclosure when energized through an electrical path;

a first electrical connector for connecting the electrical path to a power source and a second electrical connector configured to connect the electrical path to a second lamp wherein the second electrical connector may be moved between a first position where the second electrical connector is stored in the enclosure and a second position where the second electrical connector is outside of the enclosure for connection to the second lamp.

2. The lighting system of claim 1 wherein the enclosure comprises a base made of a thermally conductive material, the base being thermally coupled to the at least one LED.

3. The lighting system of claim 1 wherein the enclosure comprises a base, and a plurality of LEDs extending for substantially the length of the base.

4. The lighting system of claim 1 wherein the enclosure comprises an optically transmissive lens.

5. The lighting system of claim 4 wherein the lens is connected to a base comprising a first channel and a second channel for receiving a first edge and a second edge of the lens, respectively.

6. The lighting system of claim 1 wherein the at least one LED is mounted on a LED board that provides physical support for the at least one LED and forms part of the electrical path.

7. The lighting system of claim 6 wherein the LED board comprises a FR4 board.

8. The lighting system of claim 6 wherein the enclosure comprises a base, the LED board being mounted on the base.

9. The lighting system of claim 1 wherein the first electrical connector comprises a power cord.

10. The lighting system of claim 1 wherein the first electrical connector is configured to connect to the second lamp.

11. The lighting system of claim 10 wherein the first electrical connector and the second electrical connector comprise one of a male plug and a female plug.

12. The lighting system of claim 1 wherein the second electrical connector comprises a cable that extends from the lamp and terminates in one of a male plug and a female plug.

13. The lighting system of claim 1 wherein the second lamp comprises an enclosure being at least partially optically transmissive;

at least one LED in the enclosure operable to emit light through the enclosure when energized through an electrical path; and

a third connector configured to connect to the second connector.

14. The lighting system of claim 13 wherein the third connector comprises one of a male and female plug connected to the second lamp by a flexible cable.

15. The lighting system of claim 13 wherein the lamp abuts the second lamp when the third connector is connected to the second connector and the second connector is located in the enclosure of the second lamp.

16. The lighting system of claim 15 further comprising a bracket for connecting the lamp to the second lamp.

17. The lighting system of claim 13 wherein the third connector and the second connector are located inside one of the lamp and the second lamp.

18. The lighting system of claim 17 wherein the third connector and the second connector are located inside of an end cap of one of the lamp and the second lamp, a section of the end cap being removable to provide access to the third connector and the second connector.

19. The lighting system of claim 1 wherein the lamp comprises a base, a bracket releasably connected to the base, the bracket comprising a mounting mechanism for mounting the bracket to a support surface.

20. The lighting system of claim 1 wherein the enclosure comprises an optically transmissive lens and a base, the at least one LED being mounted on a LED board and a portion of the lens holding the LED board against the base.
