Light-emitting device

摘要

A light-emitting device comprises: a substrate that holds one end of connection terminals and on which is mounted an electronic component; a light-emitting element that is mounted on one face of the substrate; a support member on which the substrate is mounted; and a cover section that positionally locates and holds the substrate, by mounting on the support member in a condition abutting one face of the substrate. The cover section has a cover section body that covers one face of the substrate; on the cover section body, a light guide is provided, through which passes the light that is emitted from the light emitting element, in a condition in which movement thereof is restricted along directions on either side of the substrate.

1. A light-emitting device comprising:
a board holding an end of a connection terminal and on which an electronic component is mounted; a light-emitting element mounted on a surface of the board; a support member on which the board is placed; and a cover positioning and holding the board by being mounted in the support member while in abutment against the surface of the board; wherein the cover has a main cover body covering the surface of the board, wherein the cover has a pair of protrusions positioned such that the light-emitting element is interposed between the protrusions, the protrusions being integrally formed with the main cover body; the protrusions include ridges abutting against the surface of the board, and first engaging portions; and the support member has a chamber defined therein for accommodating the board and the cover, and also has second engaging portions for engaging with the first engaging portions, and the first engaging portions engage with the second engaging portions to thereby position and hold the board with the cover; and a light guide for passing therethrough light emitted from the light-emitting element is disposed on the main cover body while being prevented from moving along a direction to sandwich the board.
