Motion detector assembly for use with a decorative coach lamp

Abstract

A motion detector housing assembly is adapted to be integrated into a decorative coach lamp. The motion detector housing assembly includes a motion detector housing and a carrier assembly which may be configured in a manner to be similar to a decorative housing normally disposed on the top or bottom of the coach lamp assembly. The motion detector housing may be formed with upper and lower housing portions; together which form a generally frustro-conical configuration to match the configuration of a decorative housing disposed on the top or bottom of a lamp assembly. The lower housing portion is formed with an annular window. An important aspect of the invention is that the Fresnel lens member is configured in a generally cylindrical shape. As such, the optics of the system are improved and, in addition, decouples the lens design from the design of the lower housing portion. In order to protect the lens member a plastic lens cover is provided. The shape and size of the plastic cover is adapted to cover the window in the side wall of the lower housing portion.
