Abstract: An LED unit which serves as illumination light source to be attached to lighting equipment, includes: a mounting board on which a light-emitting element, which emits light frontward, is provided; a support pad disposed behind the mounting board; and a case disposed so that the mounting board is sandwiched in a front-back direction by the case and the support pad. The support pad or the case includes insertion holes which are three or more openings into which securing components for securing the LED unit to the lighting equipment are inserted, and the three or more openings are disposed in such a way that, when a distance between two of the three or more openings is referred to as an inter-opening distance, at least one inter-opening distance is different from other inter-opening distances.

Abstract: The present invention relates to a socket for electronic component which contains an electronic component. The socket for electronic component comprises a platy base, containers formed to be concaved on a front face of the base and to contain LED packages therein, connectors provided on side faces and connected to other members, supports each of which supports and fixes the LED package contained in the container and electrically connected to the LED package, heat conductors each of which is provided continuously from a bottom face side of the container to a rear face of the base and contacts the LED package contained in the container so as to conduct heat generated by the LED package, and terminals electrically connected to the other members coupled with the connectors and the supports. The heat generated by the LED package is conducted to the rear face of the base through the heat conductors, and effectively radiated to an installation member on which the socket for electronic component is mounted.
