SU387468A1 - IMPULSE GAS-DISCHARGE SOURCE OF LIGHT - Google Patents

Description

This invention relates to gas-discharge light sources and, in particular, to pulsed lamps used in lighting devices for general photography, light signaling, printing, etc.

Tubular flash lamps are known with a cylindrical liner that forms a coaxial cavity with the walls of the bulb in which discharge is carried out.

However, these lamps do not provide a compact body of a spherical shape with uniform brightness over the entire surface, and conventional ball lamps have a short spark, not limited to the walls and the discharge bulb and located in the middle part of the flask.

The purpose of the invention is to create a compact ball-shaped light source with a low operating voltage, uniform brightness over the entire surface and high radiation energy. This is achieved by the fact that the dielectric insert is made in the water outlet, which repeats the shape of the discharge bulb and forms a discharge cavity with its walls in the form of a spherical layer. The surface of the dielectric liner may be covered with a reflective layer; or it may be hollow, of optically transparent material, and its inner surface is covered with a metallized reflecting layer, for example silver or aluminum.

The drawing shows the proposed pulsed gas-discharge light source, section.

The pulsed gas-discharge light source is made in the form of a spherical quartz bulb / (diameter 23 mm), inside of which: a swarm is placed a hollow base 2 with a coating 3, for example, made of silver or aluminum. In the bulb feet / welded electrodes 4 - 5 on a cylindrical foil (thickness 0.05 mm). The inner surface of the bulb / and the outer surface of the hollow ball 2 form the discharge cavity 6 The lamp is assembled as follows.

The flask /, the inner ball 2 and the electrode assemblies 4 and 5 are made separately. The flask / is cut along the transverse axis with a diamond disc, a bowl 2 is inserted inside, then the flask / is welded, the sheeter gel is welded to it and the two electrode assemblies are inserted into the legs bulb / so that the walls of the inner ball 2 were equally removed from the inner walls of the bulb /.

Electrode assemblies are brewed using the technology of welding foil bushings. Pumping, training and filling the lamp is similar to conventional flash tubes. Filling - xenon at a pressure of 100 mm Hg. Art.

A lamp of a similar design can be made on flash energy from tens to thousand h of j.
