Illumination light source and lighting apparatus
View Patent ↗An LED unit which serves as an illumination light source includes: a mounting board on which a light-emitting element, which emits light frontward, is provided; a support disposed behind the mounting board; and a case disposed so that the mounting board is sandwiched in a longitudinal direction by the case and the support. The case includes a restricting portion which restricts sideward movement of the mounting board.
1. An illumination light source comprising:
a board on which a light-emitting element, which emits light frontward, is provided;
a support disposed behind the board; and
a case disposed so that the board is sandwiched in a longitudinal direction by the case and the support,
wherein the case includes a restricting portion which restricts sideward movement of the board, and
wherein the restricting portion includes at least a pair of sideward restricting portions disposed at opposite sides of the board so that the board is sandwiched from the sides by the pair of sideward restricting portions.
2. The illumination light source according to claim 1 ,
wherein the pair of sideward restricting portions restrict the sideward movement of the board by exerting pressing force on the board.
3. The illumination light source according to claim 2 ,
wherein, when the board is not placed in the case, a tip of one of the pair of sideward restricting portions is tilted toward an opposing other of the pair of sideward restricting portions.
4. The illumination light source according to claim 1 ,
wherein the board has an opening,
the restricting portion includes an inserting portion which is inserted into the opening, and
the inserting portion restricts the sideward movement of the board by being inserted into the opening.
5. The illumination light source according to claim 1 ,
wherein the restricting portion further includes a backward restricting portion which restricts backward movement of the board.
6. The illumination light source according to claim 1 ,
wherein the restricting portion further includes a forward restricting portion which restricts forward movement of the board.
7. The illumination light source according to claim 6 ,
wherein the forward restricting portion restricts the forward movement of the board by way of the board being placed thereon.
8. The illumination light source according to claim 1 ,
wherein the restricting portion is a component having insulating properties.
9. The illumination light source according to claim 1 , further comprising
a bonding component disposed between the board and the support and having heat-dissipating properties, for bonding the board and the support.
10. A lighting apparatus comprising:
the illumination light source according to claim 1 ; and
lighting equipment to which the illumination light source is attached,
wherein the lighting equipment includes:
a main body configured to cover the illumination light source; and
a socket attached to the main body, for supplying power to the illumination light source.
