LED moving head


Led moving head  lights are very attractive and fantastic stand-alone units which spin, move and swivel in practically any direction, spreading coloured lights throughout the ceiling, walls, floors, the stage and the people. The fixtures are standard products in a lot of bars, restaurants, discos and nightclubs. As a light source, the moving heads use either arc lamps or the up to date LED (light emitting diodes) technology. Using the most recent LED lighting has its advantages, but there also are a couple of drawbacks.
When referring to benefits of LED Lights, its low energy consumption is the initial thing that should be started with. It is so small, because LED lights need less power than a standard light bulb, which, in the end, suggests that a lot of units could possibly be mounted and use the energy of a standard energy supply. This is wonderful for disco and DJ parties . So alongside being very convenient to work with, LED heads may save some money from your power bill.
Another advantage of LED moving head light is the low thermal radiation. In contrast to standard stage lighting lamps, moving head fixtures utilizing LED technology do not get very hot, that means that the light show might be run without any interruptions, because of equipment fault. And also, LED lights are very long lasting - the normal life of the LED is approximately 50 000 working hours, which makes the maintenance of the units less complicated and cheaper.
LED moving head spots benefit also from their colour effects. The 3 standard colours - Red, Green and Blue (RGB) - mixed together, secures millions of mixtures and colour choices. The mix of colours is very easily managed using the help of a DMX software installed on a normal computer.
Moving heads DMX are also small, compact and portable. Because of their small dimensions and light-weight materials, it is very easy to set them up and aim them at any spot in the club or bar.
IF, LED moving head have some negative aspects too. They are coming primarily from limitation of the LED technology. LED beams cannot get a directed spotlight, because there are a lot of sources of light. It is also hard to get a "good" white light. In fact, many colours are nearly impossible to create, even using the boundless possibilities of colour mixing. Another difficulty of the LED moving heads is the fact that their depth drops off very quick in big ranges - a possible reason for this is the lack of lens. The result is that the light breaks and it cannot be excellent concentrated into a single beam. It also takes a bit more time to set up the DMX moving heads (establishing DMX addresses, light patterns programming, and so on.)
Even with their limitations, LED moving heads controlled by a DMX software are crucial for the evolution of the stage and nightclub lighting technology. They are very versatile because of the big number of DMX channels being used, which helps make them nowadays inseparable component of any light show.
