PROBLEM TO BE SOLVED: To provide an LED module which is highly convenient, has sufficient performance, and is easy to manufacture though a driver circuit mounted on a circuit board together with a plurality of LED elements is small-sized.SOLUTION: A driver circuit comprising a bridge rectifier circuit 305, a bypass circuit 320, and a current limiting circuit 340 is located around AC connection terminals 115, 117 arranged at the center of a circuit board 111, and LED dies 21 are arranged therearound. The bridge rectifier circuit 305 comprises diodes 301-304, and the bypass circuit 320 and the current limiting circuit 340 comprise depletion type FETs 324, 344 and resistors 325, 345. |
