<P>PROBLEM TO BE SOLVED: To provide a focal variable LED light source base for forming various light shapes according to the configurations of a light source by a function for adjusting the focal point of an LED light source base. <P>SOLUTION: A focal variable LED light source base is provided with: an LED light source 110; a cylindrical housing 106 covering the LED light source 110 whose outer periphery is formed with a first screw section 106a; a cylindrical focal point adjusting part 102 whose inner periphery is formed with a second screw section 102a corresponding to the first screw section 106a; and an optical lens 104 fixed to the cylindrical focal point adjusting part 102. The cylindrical focal point adjusting part 102 screws the second screw part 102a with a first screw section 106a, and rotates it with respect to the cylindrical housing 106, and adjusts a distance between the optical lens 104 and the LED light source 110. <P>COPYRIGHT: (C)2009,JPO&INPIT |
