    摘要： A reflector lamp 10 has a vitreous outer envelope 12 formed of a concave reflector 14 and a light-transmitting 16 cover peripherally sealed thereto. The concave reflector and cover are symmetrically arrayed about a longitudinal axis 18 and a substantially cylindrical, hollow neck 20 having a given depth is affixed to the concave reflector opposite the cover. The neck 20 also is symmetrically arrayed about the longitudinal axis 18 and has a substantially closed bottom 21. At least two eyelets, 22, 24, respectively, are sealed in the bottom 21 and a light source capsule 26 is positioned in the concave reflector and aligned with the longitudinal axis 18. The light source capsule 26 has a first end 28 situated in the neck 20 and a second end 30 extending into the concave reflector. The light source capsule 26 comprises a quartz arc tube 32 containing an arc generating and sustaining medium and a surrounding aluminosilicate glass shroud 34. First and second conductive lead-ins 36, 38, respectively, are sealed into a first seal 40 formed at a first end 42 of the shroud 34. Each of the lead-ins 36, 38 has a first portion 44, 46, respectively, sealed in one of the eyelets 22, 24. The first conductive lead-in 36 has a second portion 48 extending interiorly of the shroud and connecting a first electrode 50 of the arc tube and contains a bend or offset 49 to take expansion differences during operation. The second lead-in 38 has a second portion 54 terminating within the first seal 40. An outer conductor 56 has a first end 58 sealed in a second end 60 of the shroud 34 and connects a second electrode 62 of the arc tube 32. A middle section 64 of the outer conductor 56, which is surrounded by an electrically insulating sleeve 57 for at least part of its length, extends exteriorly of the shroud 34 and has a second end 66 connected to the second said lead-in 38. A conventional screw base 68 completes the lamp.
