PROBLEM TO BE SOLVED: To provide a double tube lamp which has a novel mount structure and relatively enlarges lamp power.SOLUTION: The lamp is a ceramic metal halide lamp in which two luminous tubes are encapsulated in an outer bulb to which a mouthpiece is connected and one luminous tube that is easy to be lighted is lighted at all the time. The two luminous tubes are disposed within the outer bulb while being inclined relatively to lamp axial lines in different distances from the mouthpiece and include two structs which extend within the outer bulb along a lamp axial lines and are parallel with each other and two cylindrical sleeves accommodating the luminous tubes insides, and the sleeve is fixed to the strut at three points.SELECTED DRAWING: Figure 5 |
