Abstract

A lamp that emits light and includes: a mounting board on which a light-emitting element is provided; a support disposed on a side opposite a light-emission-side of the mounting board; and a case connected to a support. The case includes a securing part which is disposed on the light-emission-side of the mounting board, and secures the mounting board to the support by sandwiching the mounting board between the securing part and the support.

First claim

The invention claimed is:

1. A lamp that emits light, the lamp comprising:
a board on which a light-emitting element is provided;
a support disposed on a side opposite a light-emission-side of the board; and
a case connected to the support, and the case comprises:
a side face;
a top face that is disposed on a support-side of the side face and in which an opening is provided; and
a securing part which is disposed on the light-emission-side of the board, has a plurality of projections, and secures the board to the support by sandwiching the board between the securing part and the support,
wherein the plurality of projections project from inside the opening of the top face of the case, extend through the opening and beyond the top face in a direction of the support, and secure the board to the support by sandwiching the board between the plurality of projections and the support.

2. The lamp according to claim 1 , further comprising
a reflector which is disposed on the light-emission-side of the board, and reflects light emitted from the light-emitting element,
wherein the reflector is disposed inside the case.

3. The lamp according to claim 1 ,
wherein the securing part secures the board to the support by exerting a pressing force against the board.

4. The lamp according to claim 1 ,
wherein the securing part is disposed to abut the board from an oblique direction.

5. The lamp according to claim 1 , further comprising
a filling component which is disposed between the board and the support, and fills a space between the board and the support.

6. The lamp according to claim 5 ,
wherein the filling component is a heat-conducting sheet that thermally connects the board and the support.

7. The lamp according to claim 5 ,
wherein the filling component is an insulating sheet that provides insulation between the board and the support.

8. The lamp according to claim 1 ,
wherein the support includes a guide component for positioning the board.

9. A lighting apparatus comprising:
the lamp according to claim 1 ; and
lighting equipment to which the lamp is attached,
wherein the lighting equipment includes:
a main body configured to cover the lamp; and

a socket attached to the main body, for supplying power to the lamp.

10. The lamp according to claim 1 , said plurality of projections extend through the opening of the top face and engage the board to maintain the board spaced from the top face.

11. The lamp according to claim 1 , said securing part is configured to support said board spaced from said top face of said case.

12. The lamp according to claim 1 , said plurality of projections being integral with the opening of the top face.

13. The lamp according to claim 1 , said securing part configured to abut against a major surface of said support.
