<p>Disclosed is a lighting device that has excellent heat radiation characteristic. The lighting device (21) is provided with a light guiding plate (31) the end faces (33) of which are the light entering faces; bases (40) that have mounting faces (41) formed at positions facing the end faces (33) of the light guiding plate (31); LED circuit boards (35) to be mounted onto the mounting faces (41) of the bases (40) so as to have the light emitting faces of the LED circuit boards (35) face the end faces (33) of the light guiding plate (31); and pairs of heat conduction walls (42, 43) that are installed at both sides of the LED circuit boards (35), upon the mounting faces (41) of the bases (40), and that are for conducting heat radiated by the LED circuit boards (35) to the bases (40). With this lighting device (21), heat generated by the LED circuit boards (35) are conducted to the base side via the heat radiation walls (42, 43), and radiated. Hence, heat radiation characteristic of the LED circuit boards (35), which are the heat generation sources, is able to be improved.</p> |
