Bright Lights. Bright Ideas. TM Brilliant Light! BL-2000SERIES RGB+ LED LIGHT ENGINE Lamina Light Engines As the market leader in the development and manufacture of super-bright LED arrays, Lamina brings solid state lighting to applications which until now were only possible with traditional lighting sources. Lamina’s LED arrays are manufactured by combining high brightness LEDs from industry-leading LED manufacturers with Lamina's proprietary packaging technology, multilayer Low Temperature Co-Fired Ceramic on Metal (LTCC-M). LTCC-M is a breakthrough in thermal performance for LED packaging technology, a key factor in determining LED life and reliability. Unmatched thermal performance coupled with package interconnectivity allows Lamina to densely cluster multiple LEDs to achieve exceptionally high luminous intensity in very small footprints. Lamina’s arrays are available in white, RGB and monochrome, from 1W to 100W, and also are available in custom packages. •HIGH LUMINOUS FLUX IN SMALL FOOTPRINT •SUPERIOR THERMAL PERFORMANCE FOR IMPROVED RELIABILITY •LONG LIFE AND HIGH LUMEN MAINTENANCE •NO MERCURY OR LEAD •CUSTOM SIZES AND SHAPES AVAILABLE Typical Applications SIGNAGE & CHANNEL LETTERS •VIDEO DISPLAY BOARDS •LED BILLBOARDS •JUMBOTRON SIGNS ARCHITECTURAL LIGHTING •DECORATIVE AND ACCENT •COVE AND UNDER-SHELF •GARDEN AND PATHWAY •STEP LIGHTS LCD BACKLIGHT •COMPUTER DISPLAYS •HEADS UP DISPLAYS MACHINE VISION BL-2000 RGB+ Lamina BL-2000 RGB+ LED arrays have independent color control for dynamic or preset display of colors. Through additive color mixing there is complete control of the various colors and white which can be displayed. Lamina BL-2000 LED arrays are configured with seven cavities, each populated with multiple LEDs. In the RGB light engine each cavity contains multiple red, green and blue LED die for optimal color uniformity, a unique feature made possible with Lamina’s packaging technology.

Mechanical Specifications 0.570 [14.48] SQ 4X MOUNTING HOLE FOR 2-56 SCREW 2 1 ATTACHMENT RECOMMENDATIONS Lamina’s BL-2000 Series is configured with solder pads compatible with Sn63 or Sn62 solder. As with many electrical devices, non-acid RMA type solder flux should be used to prepare the solder pads before application of solder. If wire attachment is performed with a soldering iron, care must be taken to minimize heat transfer to the die and minimize leaching of the solderable pads. ASSEMBLY RECOMMENDATIONS Lamina BL-2000 LED arrays are designed for attachment to heatsinks with conductive epoxy or screw down for flange mount devices with thermal grease in the joint. In limited cases, thermal transfer tape can be used, but will generally result in higher than desired thermal resistance creating excessive heat and reducing light output and die life. 3 4 0.555 [14.10] SQ 0.100 [2.54] MAX To see how you can realize all these design benefits, to request a sample, or to speak with an engineer about your design, contact Lamina at 800.808.5822 or 609.265.1401 or visit www.laminaceramics.com. laminaceramics.com REV.01.20.05 Part # BL-23F1-0246 Page 2 Bright Lights.

All Lamina LED arrays must be operated at or below 125ºC. A heat sink must be attached to the array with sufficient cooling capacity to keep the die junction below 125ºC. The temperature rise from the array base to the die junction may be determined by calculating the product of the maximum package thermal resistance and the desired operating power level. Junction Temperature Rise (Tj (rise)) = Operating Power (P) x Lamina Array Thermal Resistance (Tr) The appropriate heat sink may then be determined by: Heat Sink Thermal Resistance (ºC/W) = (125 - Tj (rise) Maximum Ambient Temperature)/P OPTICAL RECOMMENDATIONS Lamina LED arrays project a Lambertian radiation pattern, with projection angles built into the package cavity at approximately 125º. It will be necessary for users to create an optical reflector and lens structure that meets their light dispersion requirements.

Bright Ideas. TM Luminous Flux with Junction Temperature LIGHT OUTPUT VS. JUNCTION TEMPERATURE Light output from LED die will decrease with increasing junction temperature. This effect is particularly acute for die in the 580 to 750 nm range. As a result we recommend that the LED array heat sink design be optimized to maintain the die junction temperature as low as possible. ESD PROTECTION LEDs are static sensitive and susceptible to Electrostatic Discharge (ESD) damage. Lamina LED arrays must be handled using ESD damage control precautions. HANDLING PRECAUTION Contact with the silicone based encapsulant on the surface of the light engine must be avoided to prevent damage. Do not apply pressure to the silicone based encapsulant or allow it to come into contact with sharp objects. Lamina LED arrays must be handled from the sides.
