A recent round table discussion brought together a group of LED lighting experts, with the talk centred around the possibility of high power LEDs replacing the general purpose market for bulbs.
..the use of higher power LEDs as general purpose lighting sources, which have the potential to replace filament bulbs and even fluorescent tubes, has now become one of the most interesting component markets in the industry
Organised by Electronics Weekly, the expert opinion came from firms such as Osram, Dialight Lumidrives, EBV Elektronik and PixelRange.
Opinion was mixed on how quickly LEDs would, for example, start to replace fluorescent tubes in general lighting applications.
“That is the Holy Grail for manufacturers, that white LEDs will enter the traditional consumer lighting markets,” Allan Morris from PixelRange.
“The Chinese took the cost out of compact fluorescent lights and they will do the same in the white LED lighting market. I won’t say the domestic market won’t happen, but for us it is a long way down the list,” Gordon Routledge, managing director of Dialight Lumidrives
Unfortunately for white LED makers, they still need to double the efficiency of their emitters to rival fluorescent tubes, which can reach 100 lumen/Watt.
