摘要:
A base structure for a light emitting device includes a supporting device for supporting a light emitting element, a connection device for being electrically connected to the light emitting element, and a filler member. The supporting device includes a metallic material. The connection device surrounds the supporting device and includes a metallic material. The filler member fills a gap separating the supporting device from the connection device.
摘要:
A light-emitting apparatus provides a ceramic-made base body, a frame body, a light-emitting element, a conductor layer and a light-transmitting member. The base body has on its upper surface a mounting portion for the light-emitting element. The frame body is joined to the upper surface of the base body so as to surround the mounting portion, with its inner peripheral surface shaped into a reflection surface. The wiring conductor has its one end formed on the upper surface of the base body and electrically connected to the light-emitting element, and has another end led to a side or lower surface of the base body. The light-transmitting member is disposed inside the frame body so as to cover the light-emitting element, which contains fluorescent materials for performing wavelength conversion. The base body is so designed that ceramic crystal grains range in average particle diameter from 1 to 5 μm.
