<P>PROBLEM TO BE SOLVED: To realize an LED device which can improve the brightness distribution of LED light sources R, G and B and can reduce a difference in current density between the LED light sources. <P>SOLUTION: A first LED chip group consisting of a combination of one or more of LED chips (3r, 3g) for each of at least two colors and a second LED chip group consisting of a combination of one or more of LED chips (3r, 3g) for each of at least two colors are disposed separately on a component side (2a) divided into two regions by a center line (17), one for the first LED chip group and the other for the second LED chip group. The total area of luminous surfaces of all green LED chips (3g) is larger than that of all blue LED chips (3b). <P>COPYRIGHT: (C)2012,JPO&INPIT |
