An arc lamp or arc light is a lamp that produces light by an electric arc (also called a voltaic arc). The carbon arc light, which consists of an arc between carbon electrodes in air, invented by Humphry Davy in the first decade of the 1800s, was the first practical electric light. It was widely used starting in the 1870s for street and large building lighting until it was superseded by the incandescent light in the early 20th century. It continued in use in more specialized applications where a high intensity point light source was needed, such as searchlights and movie projectors until after World War II. The carbon arc lamp is now obsolete for most of these purposes, but it is still used as a source of high intensity ultraviolet light.
Radiation resistant underwater fill light
The utility model discloses a kind of irradiation resistance underwater light supplementing lamps, belong to underwater light supplementing lamp technical field, solve the irradiation range of the underwater light supplementing lamp of multiple lamp body becomes larger, but condensing effect is obviously worse, so cannot condensing clear irradiation certain object, affect the visibility when actual underwater operation problem. Including circular arc lamp panel, the lamp body of several fixed connections in lamp panel, and the light-reflecting plate of the rotation connection in lamp panel outer circle, several light-reflecting plate can be relative lamp panel flip, several light-reflecting plate synchronous rotation setting. The utility model uses, when needing large range illumination, traction electromagnet pulls connection rope, makes light-reflecting plate deflect, torsional spring accumulates elastic potential energy, turns wire pole and prevents connection rope scratch breakage. When needing condensing irradiation, traction electromagnet is powered off, release connection rope, torsional spring releases potential energy and drives light-reflecting plate reverse deflection, forms spotlight cover, makes light concentration, clear irradiation object, does not affect underwater operation visibility.
