| 摘要 |
The present invention provides a light-emitting device realizing high directivity without using a cavity, which minimizes wire-breakage deformation of electrodes and generation of bubbles. The light-emitting device has a wiring board, a LED electrically connected with the wiring board, and a glass covering the LED. Entirety of the glass is substantially spherical, and the LED is embedded in a part of the glass. Then, a curved surface of the glass preferably contact with side faces of the LED, and the LED is preferably a polygonal semiconductor chip having a rotational center in a front view.
