Abstract: A uni-planar focal adjustment system involving no reflector housing rotation for use in high-intensity discharge (HID) lighting systems. A simple mechanical drive system allows a user to manually adjust the focal point by turning a focal adjustment ring, which in turn moves a HID lamp assembly back and forth along an optical axis relative to a stationary reflector. The system utilizes only linear motion along the optical axis and does not involve rotational reflector movement. The system allows for a significantly smaller reflector through-hole, which increases the percentage of HID generated light capable of being reflectively used in the focused light beam. Finally, the focal adjustment system allows for separation of the HID lamp assembly inductor/igniter coil from the remaining ballast circuit board components, thereby further improving heat management of the lighting system, while maintaining the optimum alignment of the lamp in regards to the parabolic optic and increasing light production efficiency.
