Document Type and Number:
Japanese Patent JP5861716
Kind Code:
B2
Abstract:
[Object] To provide electric light bulb type light source apparatuses capable of ensuring high receiver sensitivity and achieving downsizing without sacrificing light distribution characteristics for lighting. [Solving Means] An electric light bulb type light source apparatus includes a light source unit with void area; a casing, with a conductive outer case and a translucent cover opposed thereto, which houses the light source unit; a circuit substrate, with at least an antenna mounted for receiving radio signals from outside the casing, housed in the casing; and a base, disposed on a side of the conductive outer case opposite to the translucent cover, for supplying power to the light source unit. The conductive outer case forms first area in the casing; the translucent cover forms second area opposed thereto. The circuit substrate penetrates through the void area so that the antenna is in the second area.
