Abstract: Lamp assemblies and methods are provided for controlling one or more operating parameters of at least one controllable light source. One example lamp assembly includes at least one controllable light source and a controller coupled to the at least one controllable light source. The controller is configured to control an operating parameter of the at least one controllable light source. The controller includes a storage medium configured to store a programming variable and an operating variable. The controller, in response to receiving primary power from a power source during a power cycle, is configured to determine whether the controller is in a programming mode based on a value of the programming variable, and in response to determining the controller is in the programming mode, modify a value of the operating variable.

Abstract: A lamp includes a housing, a lens module and bezel. The lens module has one or more integrally formed lens units. Each lens unit has an emission surface and a light gathering portion. The light gathering portion includes an incident surface. Each lens unit has a solid light-path portion formed from the light transmitting material and disposed between the incident and emission surfaces. The emission surface of each lens unit is a portion of the outer surface of the module. The lamp includes one or more light sources, each projecting light to the incident surface of a lens unit. The lamp excludes any reflecting structures directing light to the incident surface of a lens unit. The sealing bezel seals the lens module to the housing. When sealed, the lamp includes no other light-transmitting structures external to the outer surface of the lens module.
