Example Embodiment
[0010] Such as figure 1 The LU1000 type high pressure sodium lamp shown has a lamp cap 1 and a lamp shell 2, an arc tube 3 is arranged inside, and the arc tube 3 is filled with inert gas. The two ends of the arc tube 3 are provided with an electrode assembly 4, and the lamp shell 2 is airtight The maximum diameter of the olive-shaped glass bulb is not more than 78mm and the length is not more than 383mm. The arc tube 3 is fixed to the fixed frame 5 inside the lamp housing 2, and the arc tube 3 is fixed on the fixed frame 5. The material used for the arc tube 3 is translucent. Crystal alumina porcelain tube. A certain proportion of weight of sodium amalgam is also placed in the arc tube 3, generally the ratio of sodium to mercury is 1:4. The pressure of the inert gas filled in the arc tube 3 is at least 2700Pa±500Pa. The inner diameter of the arc tube 3 is 7-10 mm, and the length is 180-250 mm.
[0011] The LU1000 high-pressure sodium lamp of the present invention works at a higher...
