Opto 22's LED Dimmer Connects to Serial Networks
1/29/2013

The new network LED Dimmer from Opto 22 uses pulse width modulation technology (PWM) to control brightness from 0-100 percent for 9-30 to control VDC constant voltage LED lighting assemblies such as lamps, bulbs, strips, ropes and bars. It can also be used for other resistive-type loads.   (Source: Opto 22)

Lots of work for dimming

Al, this is an interesting approach, and as you point out it is flexible and extensible.  One thing it does bring to light (pun intended) is that controlling LEDs is much more complex than the systems they replace.  On the other hand, with the electronics we have available now, it is not a problem to develop and integrate systems such as this.

As you point out, Al, vehicle applications seem like a natural. I could see this being used in vehicle interiors. Do you happen to know if LED-based interior lights in vehicles use dimmers today?

Chuck, Don't know if dimmers are used at this point but it's easy to see that dimmer would be an advantage and unique feature for vehicles.

In a lot of vehicles today, the interior lights dim as you prepare to drive, or when leave the vehicle and close the door. I do wonder if LEDs have been able to do that up tp now. This technology would be important for those applications, I would think.

What works, works. From some current engineering students I know, serial is not a big focus at all. In fact, one of them had zero work with serial communication. Sad state of affairs indeed.

Cabe, Very surprising that serial communications wouldn't be a topic that everyone would be exposed to.  But I guess it is simple enough that young engineers can get up-to-speed on their own if they need to

Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?

In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
