Abstract:
The present invention provides a glass-sealed LED lamp which includes a mounting substrate, an LED chip mounted on the mounting substrate, a glass sealing body, and a glass bonding portion bonding the LED chip to a portion of a lower surface side of the glass sealing body. A clearance between a lower surface of the glass sealing body and an upper surface of the mounting substrate side, which causes total reflection at an interface between the glass sealing body and the clearance, is formed outward of the portion of the lower surface side of the glass sealing body.
