Referring to fig. 5, a third embodiment of the invention is:

an LED lamp comprises a light source board and the LED electric connector in the second embodiment, wherein the light source board 4 is a flexible strip-shaped substrate. The light source plate 4 has a ring-shaped structure in which both end portions are adjacently disposed, and a middle ring-shaped portion is omitted in fig. 5. A plurality of LED light sources are arranged at intervals on an inner side surface of the light source plate 4 to emit light toward a planar light guide plate (not shown) disposed at a middle portion of a ring shape surrounded by the light source plate 4.
