Patent ID: 7532479

Claim:
A spread illuminating apparatus comprising: a light conductor plate; a point light source disposed at a side surface of the light conductor plate; and a printed circuit board having a pair of lands formed on a front side thereof in which the pair of lands is provided so as to communicate with a conductive pattern and having the point light source mounted on the front side, wherein the point light source is attached to the pair of lands through electrode terminals of the point light source, each of the electrode terminals being sandwiched between the point light source and one of the lands, a throughhole is formed in each of the lands, solder is contained at least partly in the throughholes, a recess is formed between the pair of lands on the front side of the printed circuit board, a bottom of the recess is defined by a portion of the conductive pattern, and heat conductive resin is filled in a space defined by the recess and a surface of the point light source facing the printed circuit board.
