We Design Advanced Nonimaging and Imaging Optics

NEWS: LPI Europe's MF 45 CPV module project has been selected in the 3rd call of Fondo de Emprendedores organized by Fundación Repsol. click here.

2014 Acura RLX "Jewel Eye" Headlight

LPI's RXI™ free-form optics, used on the Acura RXL provide superior efficiency and beam control in a very compact package. The design software is an implementation of the LPI-patented 3D SMS Method. LPI has designed several automotive applications .

Low Profile Collimators

LPI specializes in low-profile collimators. The new V-Groove RXI works well with MR16 and portable lighting, can be designed for small beam angles, and helps blend colors of RGB LEDs and eliminating the fringe color rings of conformal phosphor coated white LEDs.

LPI's 45% MF45 CPV Module

Utilizing a combination of LPI's patented Fresnel-Köhler CPV architecture with spectrum-splitting enhacements and standard Si solar cells, the ultra-flat CPV concept should acheive 45% efficiency. A MF45 proof of concept module will be developed partially financed by Fundación Repsol. Click Here to read the full new release. Click Here to visit Fundación Repsol webpage.

Remote Phosphor Solutions

LPI specializes in remote phosphor lighting application. This A19 lamp provides superior illumination uniformity. The unique, patented approach offers improved thermal performance and efficiency. The phosphor is contained in a silicone sphere permitting higher temperature applications, such as use inside a glass globe. Click Here for our simple Light Bulb Facts document.

Ventana Optics for CPV Solar

In partnership with Evonik, the Ventana™ Optical Train is now available to the CPV industry without the high tooling cost and long lead times that developing these optics represents. This optic set is available off-the-shelf and has delivered above 32% module efficiencies for integrators.

Color Mixing and Uniformity

The Shell Mixer is placed over an RGB or RGBW source and produces perfect color mixing without compromising collimation. The étendue increase is negligible and the lens diameter is only three times that of the source. Optical efficiency is >90%.

Specialized Landscape Lighting

This custom optical design satisfies Kichler's demands for high efficiency, with a unique thermal solution. Most of the LED light exits directly from the lamp without the added losses passing through a lens or off a reflector. The LEDs are placed direcly adjacent to the outside of the housing for cooler operation.

Imaging Optics

Optical systems for ultra short-throw projection. These devices can be used as an accessory to conventional projectors (home cinema). Other applications include multimedia equipment for virtual reality systems with rear, frontal or surround projection.
