Problems solved by technology

However, due to the halides filled in the light-emitting arc tubes of the existing metal halide DC lamps, such DC lamps tend to flicker during use, and the light cannot be stabilized, which brings instability to use, and due to the flicker phenomenon Existence, it is also easy to shorten the service life of the DC lamp

Abstract

The invention belongs to the technical field of illumination of light sources, and particularly relates to a small-power metal halide direct current lamp which is stable in arc and can work under a direct current stabilizer. The small-power metal halide direct current lamp comprises a quartz bubble shell, wherein a sealed light-emitting arc tube is arranged in the quartz bubble shell, a cathode and an anode are arranged in the sealed light-emitting arc tube, one end of the cathode extends into the light-emitting arc tube, the anode is matched with the cathode, the other end of the cathode and the other end of the anode are located in the quartz bubble shell and are connected with molybdenum sheets respectively, the molybdenum sheets are connected with molybdenum rod leads respectively, the molybdenum rod leads extend out of the quartz bubble shell, the light-emitting arc tube is filled with stuffing, the stuffing comprises 3-6.5 atmospheres of xenon, 0.5-0.9mg of mercury, zinc iodide and one or more of metal halide DyI3, DyBr3, HoBr3, NdI3, CsI, InI, NaI, ScI3, ThI4 and T1I. The small-power metal halide direct current lamp can output stable light rays, bring convenience to using and reduce using cost of users, and is long in service life.

Description

technical field [0001] The invention belongs to the technical field of power supply lighting, and in particular relates to a low-power metal halide direct current lamp with stable electric arc which can work under a direct current stabilizer. Background technique [0002] The light-emitting arc of metal halide DC lamps is short. It is necessary to install the lamps into a projection reflector to focus on the position, and then make full use of the principle of light reflection to better improve the utilization rate of light from the bulb. Therefore, it is successfully used for orientation The search source for lighting. The luminous efficiency of metal halide lamps is 6-10 times that of traditional tungsten light sources, and its power is 10-20 times higher than that of tungsten lamps, that is, the same size of light-emitting area, low-power metal halide lamps can output high Dozens to hundreds of times the luminous flux, so this type of light source is especially suitable ...
