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.
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.
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.
