Fresnel lights are widely used in cinematography lighting. This spotlight optical system consists of Fresnel lens (often called threaded lens) and spherical reflector. Light source of the luminous body center is located in the centre position of spherical lens. By focusing mechanism, the light source associated with the reflector to move back and forth along the optical axis of the Fresnel lens can be obtained by continuously changing the size of the beam angle. Non-threaded surface of the Fresnel lens, usually embossed with a variety of tricks, "Moire" or "honeycomb", so make the light scattering properly, soft and uniform lighting effects, and in light of the irradiated field, no obvious boundaries that easy access light. This light beam angle can be adjusted within a range of 15 °~60 ° angle.

Outside of the box is equipped with shading baffles , in front of the lens generally include light paper framework. Most of the movie photography lighting using Fresnel spotlights the halogen tungsten lamp as light source, according to the different light source power formed from 200 watts to 20 kw series lamps.




circuit protection gives safe and reliable operation dimming to 50% of full power. This 575W HMI Fresnel Light is best suited for using in studios and theatres, provides constant and reliable low levels of light.
