Abstract
A semiconductor light emitting apparatus includes a substrate. A plurality of first electrode wirings are formed on the surface of the substrate. At least one second electrode wiring is formed on the surface of the substrate. A light emitting section is connected between a corresponding one of the plurality of first electrode wirings and the at least one second electrode wiring. The light emitting section includes a plurality of light emitting elements.
Claims19
A semiconductor light emitting apparatus, comprising:
- a substrate;
- a plurality of first electrode wirings formed on a surface of the substrate;
- at least one second electrode wiring formed on the surface of the substrate;
- and
- a light emitting section connected between a corresponding one of the plurality of first electrode wirings and the at least one second electrode wiring, the light emitting section including a plurality of light emitting elements connected in series,
- wherein each of the plurality of light emitting elements includes a first electrode and a second electrode;
- wherein the light emitting section includes:
- a first connection that connects between the first electrode wiring and the first electrode of a light emitting element at the most upstream end with respect to current flowing through the light emitting section;
- a second connection that connects between the first electrode of one of two adjacent light emitting elements and the second electrode of the other of the two adjacent light emitting elements;
- and
- a third connection that connects between the second electrode wiring and the second electrode of a light emitting element at the most downstream end with respect to the current flowing through the light emitting section.
