## Abstract

According to one embodiment, a light emitting device includes a substrate, a light emitting element and connectors. The substrate has a surface and a back face, and power supply terminals are formed on the surface. The light emitting element is mounted on the surface of the substrate. The connector includes a contact portion coming into contact with the power supply terminal on the surface side of the substrate and a connector terminal having a wire connection portion projecting on the back face side of the substrate, and a power supply wire is connected to the wire connection portion of the connector terminal.

## Claims

### Claim 1

A light emitting device comprising:
a substrate including a surface on which a plurality of power supply terminals are formed and a back face opposite the surface;
a light emitting element mounted on the surface of the substrate;
a plurality of connectors, each of the plurality of connectors including:
a contact portion coming into contact with one of the plurality of power supply terminals on the surface of the substrate;
a connector terminal including a wire connection portion projecting on the back face side of the substrate; and
a vertical portion projecting on the back face side from the surface side of the substrate, wherein an outer periphery of the vertical portion is polygonally formed, the wire connection portion is arranged in the vertical portion, and a power supply wire is connected to the wire connection portion; and
a body to which the back face side of the substrate is attached, the body including a peripheral edge portion, the peripheral edge portion including a plurality of notches, each of the plurality of notches corresponding to the shape of one of the plurality of vertical portions, wherein each of the plurality of vertical portions is disposed in one of the plurality of notches.

### Claim 2 (depends on 1)

The light emitting device according to claim 1, wherein each of the plurality of connectors is 2 mm or lower in height from the surface of the substrate.

### Claim 3 (depends on 1)

An illumination apparatus comprising:
an apparatus body; and
the light emitting device according to claim 1 attached to the apparatus body.
