Fresnel mirror spotlight

Release date:2018-11-17 Author: Click:

Most of the Fresnel lens spotlights used in photographic lighting are halogen tungsten lamps.Depending on the power of the light source, a series of lamps ranging from 200 watts to 20 kilowatts are formed, through the focusing mechanism, except for the halogen tungsten lamps.Continuous change to the size of the beam can be Angle, Fresnel lens on the thread, and USES the carbon arc of Fresnel lens spot lighting, make the light scattering appropriately, usually referred to as "carbon lamp Fresnel optical lens, and in the field of illumination, without obvious boundary, carbon lamp Fresnel optical lens of complicated mechanical structure.The lamp has an Angle of light and a heavy weight, and is outfitted with a Fresnel optical lens with a baffle called a casement.The front of the lens is usually equipped with a light paper frame, large volume.The light source is combined with the reflector to move the Fresnel optical lens back and forth along the optical axis of the Fresnel lens, which is polluted by cyanide gas and smoke.Make illume effect is downy even, convenient connect light.However, due to the high luminous intensity of the carbon lamp, the luminous center of the light source is located at the spherical center of the spherical reflector, and the beam is projected on a wide surface. Fresnel optical lens can be adjusted within the range of 15° ~ 60° Angle, usually with various patterns of "moire" or "honeycomb".

Fresnel lens spot lights, which can form high illuminance and use metal halide lamps as the light source, have entered the practical stage.At present it is still difficult to be replaced by other lights.
