LEDs came on to the scene just as I was in high school. Having had several feeble little torches on my bike as a kid, with many failed experiments to make the “feeble little wicks” a bit brighter, I saw LEDs as a wonderful technology. Throughout the years that have followed, we have brighter LEDs, and different colours – I was in Japan as the first wave of individual blue LEDs went on sale, some of which I built into a stereo amplifier I was building at the time, that still works I may say, blue LEDs and all!
Today though, after all the applications of LEDs that have evolved, driven by the purity of the light, the low power usage, low heat, and high reliability, the development of LED technology has hit a threshold that brings it into very significant use. The brightness of LEDs, and the reduced cost of manufacture, has now progressed to a level where LEDs are moving to mass-adoption. Certainly in China, a very significant portion of all light sources are already LED based. The “west” is actually in catch-up mode, even though the biggest LED companies are based there. Driven by increasing energy costs, everyone is suddenly becoming aware of LED lighting available today that actually lights things up, rather than those awful solar garden lights that struggle to light even their own casing – these only served to give a lot of people a very “dim view” of LED technology.
High power LEDs are now available, for example car headlights, security lamps etc., but most often, LED lighting is based on arrays of LEDs, often delivered on SMT PCBs. The rapidly accelerating growth of this market has seen many PCB assembly factories take on the manufacture of these LED arrays. All well and good, until the issues of LED BINNING are found which requires dynamic processing of Bills of Materials during assembly.
Take a look at our LED lean material management solution, resolving the problems around live BOM changes, plus, actually what I see so far as being the most significant benefit for manufacturing available, when implemented factory wide….
