Need help identifying this LED

[smokin]

I pulled apart an MR16 LED lamp and I'd like to know what LED it is. The lamp is a Lamina SOL MR16 GU5.3, it consumes about 8W, here's a closeup of the LED with the opto reflector removed.

The LED runs at 14V and is made up of 4 series-connected LED chips. I'm looking for detailed specs on it but I can't find any, would like any insight. Thanks.

lamina atlas, looks like. But 14V is a bit odd.

Judging by the photo its a remote phosphor silicone dome, meaning under it's mostly likely high efficacy blue LEDs, which could be made by anyone, which the yellow phosphor on top is converting to white like.

Think if it as being a handful of tiny smaller products tossed on a chip, covered in a dome and repackaged as something else.

Hope this helps.

Look familiar?

Great! The 14V may be just the 4 LEDs driven at 3.5V each, which does seem low. It could be the LED is underdriven to prevent overheating with the heat sink limited to fit in the space of an MR16 lamp. Also, I got the 14V with a DC voltmeter, if there's any PWM at the LED, it could be off. I don't have an oscilloscope to see the waveform, if any.

Also interesting is the boost-mode driver draws big current spikes. It makes the 3A xformer I used buzz a bit too loud.

Glad to see Mouser carrying new LED stuff, it's not the first time they surprise me with new toys I didn't know about. Thanks!
