5. The lamp assexnbly as claimed in claim 1 , wherein each of the first and second electrodes has a sleeve shape.
6. The lamp assembly as claimed in claim 1 , wherein the first voltage is simultaneously applied to the first power supply contacts of each first power supply module.
7. The lamp assembly as claimed in claim 1 , wherein the second voltage is simultaneously applied to the second power supply contacts of each second power supply module.
8. The lamp assembly as claimed in claim 1 , wherein the first insulating partition includes a first insulating body disposed between the first power supply modules and a first adhesive for fixing the first insulating body onto the base body, and the second insulating partition includes a second insulating body disposed between the second power supply modules and a second adhesive for fixing the second insulating body onto the base body.
9. The lamp assembly as claimed in claim 8 , wherein the first and second insulating bodies each have a length longer than a width of the first and second power supply modules, respectively, and shorter than a width of the base body, and a height substantially equal to or lower than a height of the base body and substantially equal to or higher than a thickness of the first and second power supply modules, respectively.
10. The lamp assembly as claimed in claim 1 , wherein the first insulating partition includes a first protrusion inserted into a first fixing hole formed in the base body between the first power supply modules, and the second insulating partition includes a second protrusion inserted into a second fixing hole formed in the base body between the second power supply modules.
11. The lamp assembly as claimed in claim 10 , wherein the first and second insulating partitions each have a length longer than a width of the first and second power supply modules, respectively, and shorter than a width of the base body, and a height substantially equal to or lower than a height of the base body and substantially equal to or higher than a thickness of the first and second power supply modules, respectively.
12. The lamp assembly as claimed in claim 1 , wherein the first and second insulating partitions are each formed on the base body to be integrally protruded from the base body.
13. The lamp assembly as claimed in claim 12 , wherein the first and second insulating partitions each have a length longer than a width of the first and second power supply modules, respectively, and shorter than a width of the base body, and a height substantially equal to or lower than a height of the base body and substantially equal to or higher than a thickness of the first and second power supply modules, respectively.
