Minimising running costs are at the forefront of every traffic control centre manager’s mind. The large screen videowall that is at the heart of most large control centres represents a major portion of the capital cost; it’s critically important to make sure that the display delivers on that investment by performing reliably and cost-effectively for its entire planned operational life. But in some, older, installations that can prove extremely challenging.
Until quite recently, the main source of illumination used in rear projection DLP cubes – the main display wall technology employed – came from mercury lamps. Like an old-style light bulb, mercury lamps are incandescent and therefore have a finite lifespan of only around 6000 hours. That means that in control room applications, where reliability is essential, mercury lamps needed to be changed annually in every projector at a cost of around 1000 euros each. So for an average display consisting of 8 to 16 units, that’s quite a significant running cost!
Thankfully, today the situation is very different. Modern DLP displays use LED illumination, which not only works better than mercury lamps, but delivers vastly longer lifespans. In the case of Mitsubishi Electric, our cubes can run continuously for over 11 years with requiring any replacement parts. That represents a huge cost saving. So much so, in fact, that it is often cheaper to replace an existing mercury lamp display with a modern LED solution before the end of its planned life – the cost of replacement is recouped by the dramatic reduction in running costs, which can amount to many thousands of Euros annually.
