Lamina BL-2000 Wide Flood Optic Lamina LED Light Sources 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 LED light sources are available in white, RGB and monochrome, from 1W to 100W, and also in custom packages up to 1000W.

PMMI - PLEXIMID® - Polymethyl methacrylimide Optical Performance The BL-2000 optic is designed for a typical total beam divergence of 70°, as shown in Figure 1. Total beam divergence is the full angle measured where the luminous intensity is half of the peak value. Figure 2 shows Illuminance for a BL-2000, 5500K white. These values have been calculated using the efficiency values of the optic and the formula E = I / d2, where E is the irradiance in lux, I the intensity in cd, and d the distance between the lens output and the measured point. Illuminance output depends on the luminous flux of the light source. The luminous flux values for Lamina’s light sources are provided in the product data sheets.

Alignment is achieved by centering the domes on the lens with the domes on the light source. The attachment tabs will help to position the optic. Note that the optic can be mounted in two orientations, 90° apart. However, only one of the positions will align with the light source domes. Lamina's BL-2000 Optic is designed for attachment to the surface of the light engines using epoxy or silicone adhesive. Recommended epoxy is Loc-Tite OM-50/81501 two-part, room temperature curing epoxy, or an equivalent epoxy. Adhesive should be applied in or below the holes in the outer tabs of the optic. Care should be taken to prevent adhesive from coating the inner or outer surface of the lens and light source domes. In addition, to prevent damage to the LED light source, avoid contact or pressure on the light source domes. More information on attachment of the lens to the light source can be found in the optic attachment application note on Lamina’s website.
