Embodiment 1

[0023] A blue high-intensity discharge lamp with a volume of 0.25 cm 3 The 35W discharge cavity is filled with 6 atmospheres of xenon, according to 4mg / cm 3 Filled with mercury, and according to 0.2mg / cm 3 Filled with indium bromide. Driven by a 35W transformer, it can emit blue light with a color temperature of 50,000k. The chromaticity point (x, y)=(0.1990, 0.1837) on the chromaticity diagram, and its color coordinates are as follows figure 2 shown.

Embodiment 2

[0025] A blue high-intensity discharge lamp with a volume of 0.25 cm 3 The 35W discharge cavity is filled with 6 atmospheres of xenon, according to 4.0mg / cm 3 Filled with mercury, and according to 0.4mg / cm 3 Filled with indium bromide. Driven by a 35W transformer, it can emit blue light with a color temperature of 50000k. The chromaticity point (x, y)=(0.2146, 0.2135) on the chromaticity diagram, and its color coordinates are as follows image 3 shown.

Abstract

The invention discloses a blue high-intensity gas discharge lamp. A 35 W-45 W discharge cavity is inflated with inert gases and mercury and is further inflated with metal halide capable of generating blue light, and the chromaticity coordinate (x,y) of the generated blue light is located in the range that x ranges from 0.195 to 0.22, and y ranges from 0.17 to 0.23. The indium halide is preferably selected as the metal halide, and the color temperature of the generated blue light ranges from 30,000 k to 50,000 k. The blue high-intensity gas discharge lamp has the advantages of being high in light emitting efficiency and long in service life and is suitable for automobile decorative lamps and indoor decorative lighting.

Description

technical field [0001] The invention relates to a lamp, in particular to a gas discharge lamp capable of emitting blue light with a color temperature of 30000K-50000K, which is suitable for vehicle decorative lamps and interior decoration lighting. Background technique [0002] In recent years, in foreign countries, especially in Europe and the United States, young car owners like to install car decorative lights that can emit other colors such as blue light to increase the highlights of the car. However, due to the immaturity of the technology, the luminous efficiency of the blue discharge lamps currently on the market is not high, and the effect is relatively poor. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art and provide a gas discharge lamp with a color temperature of 30000k-50000k blue light and high luminous efficiency. [0004] To achieve the above object, the present invention adopts the fo...
