4 LED moving head lights, romantic, healthy and good taste


The 4 LED moving head light is a high-tech product integrating electronics, machinery and optics. The most important thing to consider is the utilization rate of the luminous flux of the light source. The detailed display indicators include light intensity, uniformity, saturation, and spot size. There are two factors that affect the above goals. Moving head lights are generally used on stages and squares.

One is the light source, and the other is the optical system structure and material selection. Domestic and foreign manufacturers and users basically recommend OSRA M or PHILIPS1200W short-arc double-ended metal gas discharge lamps. Its characteristics are compactness, high brightness, high color temperature, good color rendering, and the ability to maintain a relatively stable color temperature during the dimming process of the light source.

There are also 4 super beam lights, moving head beam lights and led mini moving head lights and so on. The 4 LED moving head lights, that is, the filler presents a color band in the arc imaging or condenses in the arc tube to form a shadow effect, which needs to be controlled to a minimum in the optical structure design. In the optical structure, in order to obtain a uniform mixed beam, a parabolic reflector can be used. To collect divergent or narrow beams, a reflector with scale processing or surface texture should be selected.

Reflector systems made of specularly reflective materials are better than refractive systems. When several light beams need to be obtained from one light source, the refraction system of prism or lens combination can be selected. At that time, in the optical design of 1200W moving head computer lights at home and abroad, the method of lens combination was adopted, which was composed of aspherical (ie parabolic) quartz lens and so on.
