Cree MPL EZW led

[Goldigger]

Just thought i would share with you light hungry people the new cree MPL led, 1500 lumens 25v @ 250ma (per string). It's has a 11mm dome.

The XLamp MPL EasyWhite LED offers the performance, color consistency and lumen density to displace conventional light sources, in a breakthrough 12mm x 13mm package design. Combining Cree EasyWhite technology with up to 1500 lumens of light at 250mA, the MPL EasyWhite simplifies system design and increases color consistency enabling new applications previously achievable only through the use of multiple LED components. The MPL EasyWhite LED is the perfect choice for lighting applications where high luminous flux output is required from a single, small point source. Examples of specific applications include: commercial/retail display spotlights, LED retrofit bulbs, and other indoor and outdoor general-illumination applications.
The MPL EasyWhite further broadens Cree's portfolio of application-optimized LEDs, specifically designed to meet the needs of the lighting industry.

Features

• EasyWhite color temperatures
• High lumen density
• Minimum 80 CRI (2700K, 3000K)
• Electrically isolated thermal path
• Wide viewing angle (125°)

Lighting Applications

• Commercial/residential directional lighting
• LED retrofit bulbs
• General indoor/outdoor illumination

Would be nice in a 3D Maglite with 7x 14500 and two dummies in a 9AA>3D adapter with the appropriate driver .

Ok I don't think that this LED will get popular for flashlights but sounds intereseting for normal lighting. One of this will greatly light up a small room.

Thread in the LED forum. Color Temps make it interesting too

 

[Goldigger]

How about in a video light...

That's where the color temps will be most useful it think.
The viewing angle of 125 degrees is a plus as well.

As a primary light I'm not sure they are neutral enough though...

but I'll worry about it after they start shipping and I have my focusable version built

Too bad they haven't got a single emitter with selectable ck

Sorry my comment was more directed at rayman, my fault for not putting the quote..

I was just looking though the binning and datasheet and it specifies 1000lm (E0 bin) per string at 150ma:thinking:
That would mean it's capable of 3000lm at 19.9w?
That makes it just as efficient as the XP-G.

anyone know where one can buy these mounted to a star board? Working on a commercial lighting project and I am going to need about 2000 of these (1.4 million lumens).

Well, if you seriously need that many, then a custom 'star' board would make a lot of sense and you may then put more than one LED per 'star'. You may also decide on a connector system versus directly soldering to each 'star'.

Getting your own 'stars' assembled means you can have consistent binned LEDs across the entire project.

I'd suggest you would need to plan on your housing/connection/power topology/thermal management etc before worrying about where to buy pre-made stars.

In that volume I would pick up that old fashion thing called a telephone and call Cree and discuss your needs directly...

cheers,
george.

1.4 million, are you having a laugh? What stadium are you working on?

1.4 million, are you having a laugh? What stadium are you working on?

12,000 sq foot manufacturing facility with high ceilings.

Power and thermals are already worked out. I've done a ton of work with UV LEDs on other projects and the same stuff lends nicely here. I'm not familiar with Cree, my UV suppliser (ledengin) supplies them on the star board already. Since I want to keep even lighthing I want the chips spread out, one per board (1400 lumens) on 4 x 2 foot spacing.

 

[csshih]

lol, is the customer specifically saying LEDs? I find no point in such a large array!

LEP engines would be easier, and more cost effective..

..or even HMI...

Umm - call me SKEPTICAL.... You've worked out all the power and thermals etc and you are not familiar with Cree - perchance have you looked at the datasheet for the MPL????

Excuse me - who do you think makes the LED we're discussing in this thread???

cheers,
george.

Yes, I have looked at the datasheet. 25V, 150mA, 1000 lumens. I didn't see the thermal resistance of the package listed nor do I know the thermal transfer of the starboards for this package but I assume it is less than what is pumped by 6 10W LEDEngin UV packages at 365 or 390nm. I'm using copper heat sinks (bonded fin) that can handle over 200W heat dissipation. Thermals will be fine and for power I have power supplies that will pump out up to 30V at anywhere from 1.8 to 6.7A (depending on model).

I was thrown on this project less than 2 weeks ago and I realize I have some catching up to do. But I have some experience in this field and all I was asking is how I can obtain the emitters already on a star board. I checked mouser, digikey, etc and I cannot obtain a small quantity (for testing) already reflow soldered onto the star via these sources.

And as I stated in my first post in this thread - it's called a telephone and you should call Cree and talk to them. If you are after 2000 pieces of what is a fairly 'unique' LED, then they are the best candidate to discuss availability and thermal requirements of having it on a star base. If you and the company you work at are serious about building a real product then you need to talk directly to the farmer versus the cow.

For a project the type you are talking about you need to source the same binned LEDs to maintain uniform light quality, there's just a lot more to this than just buying LEDs on stars from some middle man. Given there are 3 strings within the MPL you will need to decide how each is driven and by what driver and how it will be hooked up - it's not likely you'll just find an off the shelf 'star' for such a unique LED.

cheers,
george.

Happy to help you out but bear in mind. the termination points are on top of the leds, the underside is completely isolated. The termination points are on 1.25mm pitch. We have a solution, email me at [email protected] or PM me if you interested

Ouch little harsh George, depending on the colour the led is available in Easy White down to 2 step Macadams, which in English it means it is available in an exceptionally narrow colour range without requesting special bins

Let's back up a tad...

The factory in question (3 of them actually) is the company I work for. Lighting installation is a good year away. What I'm looking for is a place to get a few stars/emitters to do some testing. I come from the UV side of the spectrum and have little knowledge of how much light is enough. I'm being told that 100 lumens per square foot is too much when using LEDs (over fluorescent). We would like to set up a test so we can continue to figure out the lighting layout of a factory under construction. We are at a point where we need to install some of the wiring in the ceiling soon but wont be installing the actual lighting for a while.

I've been trying to talk to cree for a couple days now but am having troubles getting a call back from the engineer I was referred to (supposedly the guy involved with the LED lighting project at their headquarters in NC).

Apparently this product is too new to get an off the shelf star + emitter?

Top of the package?

As I said before, I'm familiar with the LEDEngin 10W package. 4 dice in series or parallel depending on star board configuration. Surface mount package with all solder connections on the bottom of the device. I think you are familiar with this package? The Cree device has the electrical connections on top of the component? The optics side?
