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.
