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 .
Julio Chaves has just published the second edition of his widely used book,
"Introduction to Nonimaging Optics". You can purchase it through Amazon
The book includes many references to LPI innovative designs.
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.
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.
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.
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%.
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.
