Supply frequency

With LEDs working on their own driver circuits at some DC voltage levels, with many of the modern appliances working on inverters that convert AC to DC and aganin back to AC at a desired frequency , I think it is now time to relax those Frequency norms on the grid elelctric supply ( 50 or 60 hz +- 2% ).

 

Does it really now matter at what frequency the grid electricty is supplied? May be I am missing something!

Larry - I think you've hit on the really revolutionary potential. A big part of the need for the Edison base was simply the frequency that bulbs needed to be replaced. When significantly greater life span is reliably avaialble, the game changes. They can be put in essentially innacessible places and can be used in ways that incendescents never could.

When does it diverge?

The first LED lighting for general consumer use was strictly replacement, built to screw into light sockets. I am starting to see more imaginative use of what is a fundamentally different light source, but it seems like there is room to really diverge. Can we build them into walls, maybe with electronic steering of the beams? Can we paint them onto surfaces and have them change colors as our moods dictate? What else might we want to do with them?

Agreed, we're going to see increasing focus on the driver side of LED lighting. When luminaires are tested to destruction, often it is the driver that fails first. While we know how to predict the useful lifetime of an LED, the same is not (yet) true of a driver.

True enough, but HCL comes into its own in the LED era. Incandescents and fluorescents can't behave as flexibly as LEDs with respect to control of color (and spectrum). Also, the inherently directional light of LED sources is easier to direct precisely where it's needed, to the benefit of humans, other creatures, and dark skies.

Is human centric lighting really an advancement in the LED industry? I mean, doesn't most of it apply to incandescents and flourescents as well?

In spite of the strenuous objections from those with libertarian leaning, I was looking forward to the gradual ban on higher powered incandescents. Reason being, this spurs innovation and also guarantees economies of scale. And that in turn would end era of the transitional CFLs sooner rather than later. Browsing though the light bulb shelves at Lowes and Home Depot has become fun again. All good.

I think one very important ingredient in LED development will be to make that power supply circuit as sparse as possible. And it's gratifying to see this happening.

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Timesí Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
