<P>PROBLEM TO BE SOLVED: To provide an LED unit such that an LED package and a lens can have their optical axes precisely positioned and heat from the LED package can efficiently be dissipated from a heat radiation member. <P>SOLUTION: The LED unit 10 has the heat dissipating member 16, the LED package 12 mounted on a substrate 14, a frame 22, and a lens 26. The LED package 12 is fitted in a storage portion 24 formed in the frame 22, and the LED package 12 and frame 22 are positioned and fixed. The frame 22 is fitted in a storage portion 28 formed in the lens 26, and the frame 22 and lens 26 are positioned and fixed. The optical axis of the LED package 12 and the optical axis of the lens 26 are positioned through the frame 22 so as to have prescribed position relation. The positions of the LED package 12 and heat dissipating member 16 are restricted by the frame 22. <P>COPYRIGHT: (C)2009,JPO&INPIT |
