Signal lamp incorporating spatially separated clustered light emitting devices
First Claim
1. A signal lamp comprising:
- a housing having an opening and including a substrate, the substrate located opposite the opening;
a lens disposed within the opening; and
a plurality of clusters, each of the plurality of clusters comprising a plurality of light emitting devices;
wherein the clusters are disposed on the substrate to illuminate respective cluster illumination areas on the lens, each of the cluster illumination areas having a circumference and a center, the circumference of each of the cluster illumination areas intersecting the center of at least one other of the cluster illumination areas.

Abstract
The invention provides a signal lamp utilizing clustered light emitting devices and method of making the same. The invention provides a signal lamp that includes a housing having an opening and including a substrate located opposite the opening, a lens disposed within the opening, and a plurality of clusters with each of the clusters comprising a plurality of light emitting devices. The clusters are disposed on the substrate to illuminate respective cluster illumination areas on the lens. Each of the cluster illumination areas has a circumference and a center. The circumference of each of the cluster illumination areas intersects the center of at least one other of the cluster illumination areas. An optical cover can be disposed over the opening.
