LAMP ASSEMBLY
First Claim
1. A lamp assembly, comprising:
- one or more light emitting diode (LED) arrays, wherein each one of the one or more LED arrays comprises at least one LED and defines a spatial radiation pattern having a first central axis;
a controller circuit to output a current to the one or more LED arrays;
a lens array to redirect light received from the one or more LED arrays, wherein the lens array comprises, for each one of the one or more LED arrays, a total internal reflection (TIR) lens defining a second central axis aligned with the first central axis of the corresponding LED array, the TIR lens to distribute light received from the corresponding LED array from an output face of the TIR lens, the distributed light defining optical paths that are convergent, divergent or collimated with respect to the second central axis;
a base comprising a first surface to receive the one or more LED arrays, the controller circuit and the lens array, and a second surface structured to be removably received by a lamp holder; and
a light-transmissive cover attached to the base and disposed over the first surface thereof such that the one or more LED arrays, the controller circuit and the lens array are contained between the cover and the base.

Abstract
A lamp assembly including one or more light emitting diode (LED) arrays and a controller circuit to output a current to the one or more LED arrays. Each LED array includes at least one LED and defines a spatial radiation pattern having a first central axis. The lamp assembly also includes a lens array to redirect light received from the one or more LED arrays, a base and a light-transmissive cover. For each one of the one or more LED arrays, the lens array includes a total internal reflection (TIR) lens defining a second central axis aligned with the first central axis of the corresponding LED array. The TIR lens is configured to distribute light received from the LED array from an output face of the TIR lens such that the distributed light defines optical paths that are convergent, divergent or collimated with respect to the second central axis. The base includes a first surface to receive the one or more LED arrays, the controller circuit and the lens array. The base also includes a second surface structured to be removably received by a lamp holder. The light-transmissive cover is attached to the base and disposed over the first surface thereof such that the one or more LED arrays, the controller circuit and the lens array are contained between the cover and the base.
