<P>PROBLEM TO BE SOLVED: To provide a semiconductor light emitting device that can control alignment and emit light with uniform chromaticity and luminance over a wide range. <P>SOLUTION: The semiconductor light emitting device has an LED package 3 including an LED 1 and a lens portion 8 covering the LED package 3. The lens portion 8 includes a first lens 5, a second lens 6 covering its outside, and a phosphor-containing resin layer 7 filling a gap between the first lens 5 and the second lens 6. The lens portion 8 is thus arranged to perform light wavelength conversion by the phosphor-containing resin layer 7 while bringing the light from the light emission portion 3 under light distribution control. The phosphor-containing resin layer 7 preferably has the largest thickness in an optical axis 11 of the LED package 3 and decreases in thickness near the end parts. Because color unevenness can be suppressed. <P>COPYRIGHT: (C)2011,JPO&INPIT |
