<P>PROBLEM TO BE SOLVED: To provide a light-emitting device capable of improving the mixed color properties of the light of an LED chip and reducing an apparent light source size. <P>SOLUTION: The light-emitting device 1 comprises: red LED chips 21, 24, green LED chips 22, 25, and blue LED chips 23, 26; a substrate 3 where the LED chips 21-26 are packaged while the face directions of respective luminous surfaces 21a-26a are being aligned; sealing sections 40, 41 that are formed by a resin material having light transmission properties in which a light diffusion material is mixed and seal two sets of each three LED chips 21-23 and LED chips 24-26; and a lens section 5 that is formed by a light-transmitting resin material and seal the LED chips 21-26 together with the sealing sections 40, 41. The sealing section 40 has an emission surface 40a in parallel with each of luminous surfaces 21a-23a of respective LED chips 21-23, and the sealing section 41 has an emission surface 41a in parallel with each of luminous surfaces 24a-26a in respective LED chips 24-26. <P>COPYRIGHT: (C)2007,JPO&INPIT |
