For the computerised moving head light, the main thing that has changed is the light source, the other channel functions are more or less the same. The beamlight continues many of the channel functions of the previous computerised moving head lamp based on an improved light source. Usually domestic 200W beamlights, 230W beamlights, 260W beamlights, 330W beamlights, etc. are equipped with, colour discs, gobos, strobes, focus, fogging, prisms (mostly single eight-prism, some are three-prism, five-prism, gradient mirror), other functions mostly XY-axis speed fine-tuning, etc. Other features include XY-axis speed trim, etc.
However, there are also some manufacturers of prisms with prismatic movement function, the original design intention of this function is that the beam light is a concentrated class of lamps, on the one hand to strengthen the sense of the beam, but affect the fullness and splendour of the pattern. Therefore, if equipped with a prismatic amplification function, the pattern can be spread more widely without hierarchy and independence. If only a single beam is used, the audience will say that the luminaire is too harsh, and this is where the prismatic amplification effect comes in handy. Together with the focus, the prismatic magnification effect allows the pattern to be clear and brilliant over short distances.
