PPROBLEM TO BE SOLVED: To make it unnecessary to provide a support for antenna installation, and to provide a signal lighting apparatus into which an antenna is integrated as a new technological means for not impairing the fine sight of a road. PSOLUTION: A lighting apparatus 1 includes an optical unit 2 and a patch antenna 4. The optical unit 2 includes a substrate 8 with an LED 7 mounted on the front surface thereof; and a cover member 9 with visible light permeability which covers the LED 7 in front. The antenna 4 includes a patch element 11 at the rear of the front end of the LED 7 and a ground element 12 at the rear of the patch element 11. The patch element 11 is supported by a support member (reflection preventing member) 10 arranged at the front of the substrate 8. PCOPYRIGHT: (C)2009,JPO&INPIT
