LEDs From Dubai: The Royal Lights You Can’t Purchase

[Clive] had an fascinating video about LED lights from Philips. You may’t purchase them except you reside in Dubai. Apparently impressed by the ruler of Dubai, Sheikh Mohammad Bin Rashid Al Maktoum, who needed extra environment friendly and longer-lasting bulbs. The key? A traditional LED bulb makes use of an LED “filament” at 1 watt every. The Dubai bulbs run at a few fourth of that which implies they want extra LEDs to get the identical quantity of sunshine, however they need to last more and function extra effectively.

After exploring the brightness and colour of various lamps, [Clive] tears one up and finds some surprises inside. The LEDs recover from 200V every and the driving force circuit has a number of pairs of elements, probably to maintain the scale small for the excessive voltages concerned, though it could possibly be to enhance reliability, [Clive] wasn’t certain.

By decreasing the facility, [Clive] was capable of depend that every LED strip incorporates 21 LEDs. He additionally notes a number of the oddities in development that seem like for reliability and ease of producing. We aren’t certain how that compares to the development of typical bulbs. The circuit features a bridge rectifier and a linear present regulator utilizing a MOSFET.

The bulbs value a bit extra, however in case you issue within the possible lengthy life, their whole value over time must be cheap. Total, it’s fascinating {that a} good design got here from what quantities to authorities regulation. In fact, there’s a value: in alternate for the event of the bulbs, Philips has the unique proper to make and promote the bulbs for the subsequent a number of years. They count on to promote 10 million lamps by the tip of 2021, though they’re solely accessible, presently, in Dubai.

The final time we appeared in on Dubai, their police had been flying quadcopters. If you need a teardown of a extra typical bulb, we’ve checked out that earlier than, too.
