Abstract
A lamp assembly for outdoor purpose includes a housing, a lamp module, and a potted power module. A support ring is positioned within the housing so as to connect the housing to the lamp module. An additional tilt ring may be connected therewith to provide an additional degree of movement. The support ring and, if included, the associated tilt ring has the ability to key the lamp module to the housing. This makes it possible to relamp or perform maintenance on the lamp without affecting the aim or distribution of the light. In addition, the lamp assembly preferably includes at least one flue plate disposed between the lamp module and the housing to form at least one flue, the at least one flue advantageously creates and maintains convective cooling within the housing of the lamp assembly during operation.
