<P>PROBLEM TO BE SOLVED: To do away with soldering between an LED package and a base material, prevent generation of soldering cracks due to thermal shock and yet to secure sufficient insulation between the LED package and a body part in a light-emitting unit with the LED package on the base material covered with a cover and fixed to the body part of a lighting fixture. <P>SOLUTION: The light-emitting unit 1 is provided with a base material 2, an LED package 3 loaded on the base material 2, a cover 4 covering the base material 2 and the LED package 3, and screws 5 fixing the cover 4 and the base material 2 to the body part 11 of the lighting fixture 10 without engaging with the LED package 3. The cover 4 is provided with a terminal stage 43 for fixing a spring member 6 for feeding power through contact with the LED package 3. With this, power is fed from the spring member 6 to the LED package 3 through direct contact, generation of soldering cracks due to thermal shock is prevented by doing away with soldering between the LED package 3 and the substrate 2, and further, insulation between the LED package 3 and the body part 11 can be sufficiently secured. <P>COPYRIGHT: (C)2012,JPO&INPIT |
