Structure and function:
The searchlight is composed of a light source and a reflector, and
generally contains one or more optical lenses in the front section.
The light is first collected into a beam by a reflector (curved
mirror or spherical mirror), and then controlled by the position
and combination of the optical lens, and finally projected out.
Searchlights are mainly used in the lighting of vehicles, movie
shooting, theaters, and buildings or exhibitions.
Searchlight:
With the help of a reflector or lens, the outgoing beam is
concentrated in a small solid angle, so as to obtain a lamp with a
larger light intensity. According to the International Commission
of Illumination, a searchlight is a projection light whose
half-peak angle of the emitted beam (the angle between the maximum
light intensity and 50% of the maximum light intensity on a plane
passing through the maximum light intensity) is less than 2°.
Around 1870, searchlights using carbon arc lamps as light sources
appeared in the world. In World War II, searchlights were mainly
used at night to search for targets for anti-aircraft guns. Modern
searchlights are mainly used for ship navigation (such as marine
searchlights) and signal signs. Searchlights generally use halogen
tungsten lamps as light sources, and some use ultra-high pressure
mercury lamps, metal halide lamps and ultra-high pressure xenon
lamps as light sources.
Species:
Ordinary searchlight-a simple box containing a light source
(usually a halogen rod) and a reflector (usually a spherical
mirror).
Mirror type searchlight-The distance between the light source and
the lens placed in front of the curved mirror can be adjusted.
Lens-type searchlight-the light source is placed in front of the
spherical mirror, and the lens (flat inside and convex outside) is
placed in front of the light source, so it is also called convex
lens type searchlight (English abbreviation PC). The large version
of this type of searchlight will cause the glass to break due to
the thickness of the convex lens. Therefore, people use lenses
whose diameters are gradually reduced to solve this problem. Such
searchlights are called Stufenlinsenscheinwerfer or
Fresnellinsenscheinwerfer according to the name of the inventor
Augustin Jean Fresnel. Lens-type searchlights can adjust the angle
of light emission by adjusting the distance between the light
source and the lens.
