Lighting connector devices and uses thereof

1. A lighting connector, the lighting connector comprising:

(a) an upper housing having:

plural connector pins, and

one or more interlocking grooves; and

(b) a lower housing, the lower housing having a plurality of connector pin guide holes, and one or more interlocking tongue portions,

the lower housing being connectable with the upper housing to form the lighting connector by coupling at least one of the one or more interlocking grooves with at least one of the one or more interlocking tongue portions, and by coupling at least one of the plural connector pins with at least one of the connector pin guide holes,

wherein the upper housing and lower housing are shaped to facilitate interfacing of the lighting connector with at least two lengths of lighting apparatus in a right angle with one another, so as to mechanically and electrically connect the at least two lengths of lighting apparatus to one another upon coupling of the upper housing and the lower housing.

2. The lighting connector according to claim 1 , wherein each of the plural connector pins comprises an embedded portion situated within the upper housing, and plural protruding portions, at least one of the protruding portions being configured to couple with a respective corresponding one of the at least one connector pin guide holes.

3. The lighting connector according to claim 1 , wherein each of the at least two lengths of lighting apparatus interfacing with the connector comprises an encapsulant and at least one conductive bus embedded within the encapsulant, and, upon coupling of the upper and lower housings, the protruding portions of each connector pin penetrate the encapsulant of at least one of the lighting apparatuses so as to contact the at least one conductive bus and to effect an electrical coupling between the at least two lengths of lighting apparatus.

4. The lighting connector according to claim 3 , wherein each of the connector pins are made of an electrically conductive material.

5. The lighting connector according to claim 3 , wherein the embedded portion of each of the connector pins is insert-molded into the upper housing.

6. The lighting connector according to claim 3 , wherein the protruding portions of each of the connector pins comprise a barbed tip, inverted “V” tip, or a “U” tip.

7. The lighting connector according to claim 3 , wherein the upper and lower housings are made of a thermoplastic.

8. The lighting connector according to claim 3 , the lower housing further comprising at least two openings, each opening for receiving an end portion of a length of lighting apparatus.

9. The lighting connector according to claim 8 , further comprising a gasket in a lining of the at least two openings.

10. The lighting connector according to claim 1 , wherein the lighting connector is an L-branch lighting connector.

11. A lighting system comprising at least one lighting connector of claim 1 .

12. A method of electrically and mechanically connecting at least two lengths of lighting apparatus so that the end portions of the at least two lengths of lighting apparatus are at a right angle, each lighting apparatus having at least one conductive bus, using a connector having: an upper housing having one or more interlocking grooves, a lower housing having one or more interlocking tongue portions, connector pins embedded in the upper housing, and one or more openings and/or slots formed in the lower housing, the method comprising:

coupling an end portion of a first one of the at least two lengths of lighting apparatus into at least one of the one or more openings and/or slots;

coupling a second one of the at least two lengths of lighting apparatus into at least one of the one or more openings and/or slots; and

pressing the upper housing and the lower housing so as to couple corresponding ones of the interlocking grooves of the upper housing with interlocking tongue portions of the lower housing, so as to penetrate the connector pins into the at least two lengths of lighting apparatus so as to contact the conductive buses of the respective lighting apparatus.

13. The method according to claim 12 , wherein the at least two lengths of lighting apparatus comprise an encapsulant, and the connector pins penetrate to the encapsulant in the pressing step.

14. The method according to claim 12 , wherein the penetration of the respective at least two lengths of lighting apparatus effects an electrical connection between the at least one conductor buses of the at least two lengths of lighting apparatus.
