Abstract
The present invention is a spotlight with adjustable focus that has a focus fixing mechanism to prevent inadvertent changes to the focus of the light, while still allowing user-friendly intentional adjustment of the focus. The mounting neck of the reflector assembly rotates on threads on the lamp assembly so that the focus of the light may be adjusted. The focus is fixed in position by a plurality of ridges and valleys on the lamp assembly that mate with corresponding ridges and valleys in the neck of the reflector assembly. The neck of the reflector assembly is sufficiently flexible or expandable so that the focus of the lamp may be intentionally changed by applying sufficient rotational force, without requiring the user to physically interact with any sort of detent or locking mechanism. The neck is sufficiently rigid so that the reflector assembly will not rotate as a result of incidental vibrations or movement.
