Problems solved by technology

[0003] 1. The luminous efficiency of the lamp is low, the color reproduction is poor, and the balance of red, blue and green (three primary colors) in the emitted light is not good, especially the lack of red light;
[0004] 2. It takes a long time for the lamp to reach a normal stable light output when it is started, generally more than 5 minutes
[0005] 3. The illuminant in the lamp is relatively large, and the effect of using it as a point light source is not ideal, and the utilization rate of the projection light source and liquid crystal display light is very low
[0006] 4. When the lamp is started, the electrode in the lamp will be splashed, which will cause electrode spatter and other attachments to adhere to the inner surface of the lamp cavity, which will affect the effect of the light and reduce the service life of the lamp.

Embodiment Construction

[0020] In the accompanying drawings, 1 is the lamp body, 2 is the lamp cavity, 3 is the lamp cap, 4 is the electrode, 5 is the molybdenum foil, and 6 is the outer lead.

[0021] The shell of the lamp body 1 is made of high-quality quartz glass, the hydroxyl group of the quartz glass is less than 1ppm, including 1ppm, and the volume of the lamp cavity is 113cm 3 , the electrode is made of high-quality pure tungsten, with a diameter of 0.45mm, and the electrode ring at the end is wound with a tungsten wire of φ0.15mm. The introduction amount of the mixture of mercury and halide in chamber 2 is 24 mg; the ratio (by mass ratio) of mercury to halide is 20:1, and the introduction amount of xenon gas is 5×10 5 Pa, the load power in the lamp cavity 2 is 1.33w / cm 2 .

[0022] In addition, the present invention also adopts that the distance between the two electrodes 4 is 1.0 mm and 1.7 mm, and the amount of the mixture of mercury and halide introduced into the lamp cavity 2 is 0.1 mg...

Abstract

The present invention belongs to the field of discharge lamp, and especially relates to superhigh pressure mercury lamp as projecting light source and in LCD display, which has two oppositely positioned electrodes separated by 0.8-1.8 mm, and inside the lamp, is filled mixture of mercury and halide in the amount of 0.08-0.25 mg / cu cm and in the weight ratio of 10-30. The power load in the inner wall of the lamp is 120-250 W / sq cm.

Description

(1) Technical field: [0001] The invention belongs to the field of discharge lamps, and in particular relates to a mercury lamp widely used in ultra-high voltage fields such as projection light sources and liquid crystal displays. (two), background technology: [0002] At present, the following deficiencies exist in the field of common discharge lamps: [0003] 1. The luminous efficiency of the lamp is low, the color reproduction is poor, and the balance of red, blue and green (three primary colors) in the emitted light is not good, especially the lack of red light; [0004] 2. It takes a long time for the lamp to reach a normal stable light output when it is started, generally more than 5 minutes. [0005] 3. The illuminant in the lamp is relatively large, and the effect of using it as a point light source is not ideal, and the utilization rate of the projection light source and liquid crystal display light is very low. [0006] 4. When the lamp is started, the electrode i...
