Document Type and Number:
Japanese Patent JP6823800
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a light-emitting module having various types of light-emitting elements capable of being driven with the same spec power while preventing irregular color, and illumination apparatus.SOLUTION: A light-emitting module 1 includes: a substrate 10; plural main light-emitting elements 20r to 20o including three types or more different wavelengths; and plural sub light-emitting elements 20i which emit light out of a color chromaticity range in an x, y color chromaticity diagram, reproduced by the main light-emitting elements. Each of the sub light-emitting elements has a smaller surface area of the upper plane than that of the main light-emitting elements and the number thereof is selected so that the applied voltage is the same as the voltage applied to the main light-emitting elements.SELECTED DRAWING: Figure 1
