Cree CXA LED is Too Bright!

Cree CXA 1520 high-density LED arrayThe new Cree chip-on-board (COB) high-density (HD) LEDs can pack more than 100 die onto the light emitting surface (LES), making this family of LEDs the only 9mm package able to replace ceramic metal-halide (CMH) PAR30 sockets; over 40,000-cd center beam candle power (CBCP) is required of a replacement lamp for PAR30 CMH sockets.

Thoughts from a Lighting Designer
Mark Groenke, vice president of engineering at ConTech Lighting, said in this LEDs Magazine article “The CXA1520 LED array enables ConTech Lighting’s newest LED fixtures to exceed the efficiency and life of our ceramic metal-halide fixture offerings while maintaining intensity and color quality. The new CXA1520 LED array delivers an impressive amount of light from a very small source. I have not seen another integrated array that can match this level of lumen density.”

Cree is the Leader
LEDSupplys’ largest selection of LEDs are Cree LEDs as Cree continues to lead the industry by offering this new array that offers double the lumen output of competitors’ products and prior Cree products with the same LES. Cree has the the largest portfolio of integrated LED arrays and the only portfolio of HD LED arrays. Having multiple size and lumen-output options from the extended CXA product family helps address a wide range of lighting applications from small-form-factor halogen and CMH, to sports, stadium lighting and directional accent lighting. list of domains Lighting manufacturers can also take advantage of the CXA’s ability to increase light output without increasing size.

Before & After
Before now, you could achieve the CMH replacement using the 19-mm CXA2530 LEDs, albeit at a much higher power level and with less ability to control the beam. Cree built a reference design that demonstrates 40,000-cd levels in the center of a beam with the LED delivering only 2000 lm at 22W; and if previous designs used the CXA1507 and CXA1512 LED array the new CXA1520 LED array shares the same light-emitting size as the CXA1507 and CXA1512 LED arrays, allowing lighting designers to address very high output applications without changing the optics.
