Title:

LIGHTING CIRCUIT, LAMP AND ILLUMINATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2012/011288

Kind Code:

A1

Abstract:

Disclosed is a lighting circuit which is for a lamp that uses an LED as a light source, and which facilitates design of a resonance circuit. A lighting circuit (11) of a lamp, which uses as a light source a light-emission section (39) comprising an LED, is provided with: a rectifier circuit (31) that rectifies power supplied by way of a socket (28) from an A/C power source; an inverter circuit (33) that is connected to the output side of the rectifier circuit (31) and outputs A/C power to the LED; and a resonance circuit (35) that is connected to the output side of the inverter circuit (33). The resonance circuit (35) is constructed by a series circuit of an inductor (L) and a capacitor (C1), and the light-emission section (39) is connected in series to the resonance circuit (35).
