ABSTRACT:
An LED illumination device can include a bridge connection circuit that includes five LED chips. The LED chips can be installed such that four LED chips, through which half-wave rectified current flows, are disposed in a generally cross-shaped opposed arrangement with the remaining LED chip interposed therebetween. The remaining LED chip can also have a full-wave rectified current flowing therethrough. Half-wave rectified currents having phases shifted by 180° (half the period) can flow through respective LED chips installed at a generally right angle. The placement range for the five LED chips can be limited, and the LED chips can be sealed with a wavelength conversion material.
