Embodiment Construction

[0014] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0015] Such as figure 1 As shown, the light-emitting structure of a single-ended double-tube ceramic metal halide lamp of the present invention includes an arc tube 1, and the arc tube 1 is a transparent ceramic shell. The arc tube 1 is a single-ended integrated double-cavity structure. A pair of electrodes 2 are respectively arranged in the tube chambers 1-1 and 1-2 of the arc tube. The main body of the electrode 2 is composed of a tungsten rod section 2-1 and a niobium rod section 2- 2. It consists of two parts. The tungsten rod segment connected to the end of the niobium rod segment is wound with a molybdenum spiral 2-3. The front end of the tungsten-niobium rod is provided with an electrode tip 2-4 with a curved surface. The outer extension is protrusion 2-5. In each pair of electrodes, the protruding positions of the electrode end...

Abstract

The invention discloses a single-ended dual-tube ceramic metal halide lamp light-emitting structure. The single-ended dual-tube ceramic metal halide lamp light-emitting structure comprises an electric arc tube and electrodes arranged therein. The single-ended dual-tube ceramic metal halide lamp light-emitting structure is characterized in that the electric arc tube is of a single-ended integrated dual-tube cavity structure; a pair of electrodes is arranged in each tube cavity of the electric arc tube; end heads of each pair of electrodes are provided with mutually-corresponding arc-shaped protruding positions. The single-ended dual-tube ceramic metal halide lamp light-emitting structure of the invention has the advantages of simple structure, stable operation and low manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of ceramic metal halide lamps, and more specifically relates to a light-emitting structure of a single-ended double-tube ceramic metal halide lamp. Background technique [0002] It is no accident that ceramic metal halide lamps have received great attention from the lighting industry. After more than ten years of practical tests, their superb performances such as high luminous efficacy, high color rendering and long life have been recognized by people. Although even the most famous brands of ceramic metal halide lamps on the market have many flaws, this does not conceal their advantages. In recent years, the application of ceramic metal halide lamps is being developed and popularized in various fields, and various corresponding lamp structures suitable for special functions are being continuously developed. However, because ceramic metal halide lamps have always had hot start obstacles, they have not been u...
