LED LAMP LIGHTING DEVICE INCLUDING LED LAMP AND METHOD FOR CONTROLLING ELECTRIC CURRENT OF LED LAMP

摘要

An LED lamp (20) according to an embodiment of the present invention includes a pair of input terminal units (20a 20c) a rectification circuit unit (22) and a LED light emitting unit (24) the LED lamp (20) having: a variable inductance unit (L50 L60) for causing an alternating current to be passed via the rectification circuit unit (22) from one input terminal unit of either of the input terminal units (20a 20c) to the other input terminal unit; an electric current detecting unit (31) for detecting the magnitude of the alternating electric current passed to the LED light emitting unit (24); and an inductance variation control unit (32) for varying the inductance value of the variable inductance unit (L50 L60) in response to the size magnitude of the alternating electric current detected by the an electric current detecting unit (31).
