摘要:
A high intensity discharge lamp, the lamp including a light emitting vessel having a wall made of ceramic material that defines an inner space with a first end portion having a respective first opening formed therein and a second end portion having a respective second opening formed therein, two discharge electrodes, with a first electrode extending therethrough the first opening of the first end portion of the vessel and a second electrode extending therethrough the second opening of the second end portion of the vessel, together forming a gap between ends of the discharge electrodes positioned within the vessel, wherein the light emitting vessel defines an inner space characterized by an inner diameter ranging from and including 1 millimeters to 3 millimeters and an inner length between and including 5 millimeters to 10 millimeters, wherein the wall of the vessel has a thickness ranging between and including 0.3 millimeters to 0.8 millimeters, wherein each tip of the electrodes within the vessel have a shank diameter ranging between and including 0.2 millimeters to 0.55 millimeters, and wherein the gap between the ends of the electrodes positioned within the vessel is smaller than 4 millimeters.
