Is the searchlight light made from a point light source?
The searchlight is formed from a point light source.The composition of the searchlight: 2000W-5000w xenon lamp as a light source, 100 cm in diameter, rhodium plated disk concave mirror.
The light source of the searchlight can be equivalent to a point light source. It can be said that the probe light is formed by a point light source.
Working principle: the light source placed at the focal point of the concave mirror, the light emitted from the light incident to the concave mirror is concave mirror reflection into parallel light irradiation distance of 10 km.
The searchlight has a powerful light source and a concave mirror that focuses light on a particular direction for use in remote lighting and searching. A large beam of light can be obtained by concentrating a beam of light in a very small solid angle (usually less than 2 degrees) with a mirror or lens. Considering the size, weight and ease of operation of the device, most of the searchlights are equipped with a tripod or movable carrier, and large searchlights even have special trucks as carriers. It has a beam of light, the longest range of 12 km, the beam angle of 0.6-0.8 degrees, the beam size can be adjusted freely.
