PerkinElmer Elcos GmbH (Pfaffenhofen, Germany) offers the ACULED (All Color Ultrabright Light Emitting Diode) multiuse, multicolor LED platform for a variety of specialty lighting applications. The ACULED platform uses multi chip-on-board (COB) technology to provide a high-power light source. The close chip placement achieves an even white color mix. Precise multicolor mixing is achievable by adjusting each chip individually using one blue, one red, and two green power chips. Mixing is made possible because each LED has its own cathode and anode. The light sources operate as a Lambertian emitter with 120° aperture. ACULED is designed for operation in applications including vision systems, architectural lighting, and medical lighting.
