<P>PROBLEM TO BE SOLVED: To provide a light emitting device which improves the luminous efficiency without causing a size to be significantly increased. <P>SOLUTION: The light emitting device has many LED chips 10 including three types for emitting the blue-based, green-based and red-based colors, a mounting substrate 20 where such many LED chips 10 are mounted, a framework 40 for surrounding all the LED chips 10 at the mounting surface side of the LED chips 10 on the mounting substrate 20, a sealing section 50 which is formed with a transparent resin material filled into the inner side of the framework 40 for sealing a bonding wire 14 connected to each of the LED chips 10 and individual LED chips 10 while keeping the elasticity, optical members 60 which are placed in piles on the sealing section 50, and a domy protection cover 70 which covers the optical members 60 at the side of light emission surfaces 60b of the optical members 60 as a molded part formed with a transparent material and which is arranged such that an air layer 80 is formed between the light emission surfaces 60b and framework 40. <P>COPYRIGHT: (C)2008,JPO&INPIT |
