Document Type and Number:
Japanese Patent JP5699273
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a lighting apparatus that includes a plurality of plane-shaped light sources and in which the load to circuit components is reduced so as to have a long life span.SOLUTION: A lighting apparatus comprises a lighting device 1 that is connected to a commercial supply AC and a plurality of plane-shaped light sources 2 that is connected to the lighting device 1 and is lighted up by the supply of lighting power from the lighting device 1. Each of the plane-shaped light sources 2 includes, for example, an organic electroluminescence (EL) element, and each of the plane-shaped light sources is set so as to emit light with illumination in accordance with the duty ratio of the input lighting power. The plane-shaped light sources 2 are connected in series and have a low composite capacitance of the whole of the plane-shaped light sources 2, as compared to the case where the plane-shaped light sources 2 are connected in parallel.
