Abstract
A semiconductor light emitting device (A1) includes a case (1) and a plurality of semiconductor light emitting elements (3) arranged in the case. The case (1) is formed with a plurality of reflectors (11) each in the form of a truncated cone surrounding a respective one of the semiconductor light emitting elements (3). Current is applied to each of the semiconductor light emitting elements (3) via two wires (6). Each of the wires (6) includes a first end, and a second end opposite to the first end. The first end is connected to the semiconductor light emitting element (3), whereas the second end is located outside the space surrounded by the reflector (11).
Claims8
A semiconductor light emitting device comprising:
- a plurality of semiconductor light emitting elements arranged on a plane;
- and
- a plurality of reflectors each in form of a truncated cone, each of the reflectors surrounding a respective one of the semiconductor light emitting elements;
- wherein each of the reflectors is provided with a shared edge and a non-shared edge,
- wherein each of the reflectors is partially in contact with the adjacent reflector at the shared edge,
- wherein a height of the shared edge measured using the plane as a reference is lower than that of the non-shared edge, the shared edge being straight as viewed in a direction perpendicular to the plane,
- wherein the semiconductor light emitting device further comprises two heat dissipaters spaced from each other so as to sandwich a center of the semiconductor light emitting device, and
- wherein each of the heat dissipaters is provided with a first surface on which the semiconductor light emitting elements are mounted and a second surface opposite to the first surface, the second surface being exposed to the outside of the semiconductor light emitting device.
