<P>PROBLEM TO BE SOLVED: To provide compact electronic equipment capable of emitting heat of a transformer to a case and further assuring electric insulation between the transformer and the case without requiring a heat-radiating relay member. <P>SOLUTION: A lighting device 5 includes a metal case 11, a circuit module 31 and an insulating sheet 45. The case is formed by a base 12 having a base main wall 12a and a base side wall 12b, and a cover 21 having a cover main wall 21a and a cover side wall 21b connected to the base side wall. A pressing piece 25 is raised by cutting from the cover side wall. The pressing piece has an engaging edge 25a which is so inclined as to approach the cover main wall from the front edge toward the root thereof. The circuit module includes a circuit board 32 and a plurality of electric components which contain the transformer and are mounted on the circuit board. The engaging edge is engaged with the side edge of the circuit board from the base main wall side, and the sheet is sandwiched between the cover main wall and the transformer, to press the transformer against the inner surface of the main wall. <P>COPYRIGHT: (C)2011,JPO&INPIT |
