ACULED™ LHS-AL25 Lens System Standard Optics for ACULEDTM RGB Light Source Introduction The ACULED LHS-AL25 lens system is designed to collect and guide the light emitted by the ACULED RGB LED. Easily attachable lenses lead the beam into a smaller angle to provide more light power in a particular certain direction. With the LHS-AL25, Excelitas’ ultra bright ACULED RGB light source is even further “setting the mood” in illumination. Test it using our Evaluation Kit. Features and Benefits High luminous flux by collecting lenses Small footprint due to complex lens design Optics including micro lenses for excellent color mixing Two different aperture angles available, customized optics on request Increased luminous intensity compared to bare ACULED Applications High-power light source for general illumination Vision systems Architectural lighting Mood lighting Medical lighting Backlighting Displays and signs

Specifications Material Optical grade PMMA Operating and Storage Temperature - 40° C to + 80° C Optical grade PMMA Divergence Angles typically 22° with 2.6 mm micro lenses (medium beam) typically 32° with 1.7 mm micro lenses (wide beam) Flammability class (1.5 mm nominal thickness): Optics (PMMA): class HB second IEC 60695-11-10 Lens holder (PC-ABS): UL recognized, 94 V-0 flame class rating Figure 1 Top view of optics (micro lens structure).

Assembly The ACULED LHS-AL25 should be mounted directly to the substrate (heat sink), where the ACULED itself is mounted to. The four feet of the holder have to be planar to the backside of the ACULED copper board to achieve proper beams. Please refer to figure 2 and 3 for details of the holder. Figure 3 This figure shows the holder upside down. The steps at the legs should stand on the substrate where the ACULED is mounted on to achieve proper vertical alignment. The ACULED lens should be placed on the optical axis of the ACULED. This is defined as the middle of the gap cross between the four...

Figure 6 Dimensions and tolerances of the ACULED. The middle of the gap cross defined by the four chips should be on the optical axis of the lens. Attention: Using lenses can concentrate the total amount of light emitted by an LED. Take care to avoid any direct exposure to human eyes in your application.
