ELIMINATING THE ULTRAVIOLET HAZARD FROM HID LAMPS

Two methods are discussed for extinguishing a lamp's arc tube when the outer envelope is broken. One method utilizes a mechanical switch, and the other method utilized an oxidizable fuse. It is felt that the mechanical switch approach is expected to be the more reliable method because is extinguishes the arc immediately when the bulb is removed. The design does not depend on the electrical characteristics of the arc tube or ballasts, has no effect on the lamp characteristics, and is probably the least expensive course.
