DETACHABLE LED LIGHTING APPARATUS STRUCTURE

摘要

The present invention is a detachable LED lighting apparatus structure coupled with a lamp and an LED module, with the lamp fixed onto walls or ceilings and connected to a power supply. The LED module has plural LED elements protruded toward an undersurface, and the structure comprises a first divided type connector having a first pin inserted into the lamp to fix the first connector to the undersurface of the lamp, a first coupling groove into which one end of the LED module is inserted, and a first connection terminal in contact with the LED module seated in the first coupling groove; and a second divided type connector facing the first connector with a predetermined spacing therebetween, which has a second pin to be inserted into the lamp to fix the second connector to the undersurface of the lamp, a second coupling groove into which the other end of the LED module is inserted, and a second connection terminal in contact with the LED module seated in the second coupling groove. The first and second, one-body or divided type connectors fixed onto the lamp of the detachable LED lighting apparatus structure according to the present invention enable the assembly/disassembly of the separately attached LED modules for use, wherein the interior of the first coupling groove is comparatively longer than that of the second coupling groove; and additional coupling pins are formed inside the second coupling groove, with bottom ends thereof being fixed into the second coupling groove, to slide into a coupling groove formed in one end of the LED module, such that the LED module can be easily fixed. As a GROUND terminal provided to one end of the LED module contacts the first connection terminal before (+) and (-) terminals provided to one side of said LED module, over-voltage impulse current and electric sparks are avoided which protects LEDs from electric shocks. When one of the LEDs is damaged only the damaged LED module is replaced instead of the entire lamp, resulting in reduced waste, low maintenance and superior expandability.
