LEP Light Source

We can customize the emission from any LEP light source or flashlight. LEP stands for laser-excited phosphor and is an exciting new solid-state lighting technology more powerful and efficient compared to LEDs. An LEP light source generally works by focusing a blue laser on a phosphor element mounted on a substrate. The laser can be either reflected by or transmitted through the phosphor and converted to narrow or broad-spectrum light, depending on the choice of phosphor materials. In an LEP light source or flashlight, a broadband yellow phosphor is used to produce a powerful white light beam that can be projected for long throw or distance. LEP flashlights can be used as tactical search lights or to send SOS distress signals.

By modifying the LEP modules, a wide range of spectral colors can be achieved. This includes both the visible as well as the invisible parts of the spectrum, such as the infrared (IR). A near-infrared LEP, for example, can be used as a powerful spot lighting source for long-distance night-vision cameras and instrumentation. An LEP-based SWIR source can be used for long-range communication or for atmospheric studies.

A phosphor-converted NIR/SWIR LEP can be used as a compact and portable source for optical absorbance, reflectance, and transmission measurements. It can operate at low DC voltages and deliver more infrared optical output compared to conventional IR LEDs or lasers. Different wavelengths of infrared light can be customized for different purposes. IR LEPs can deliver narrow-band, multi-band, or broadband radiation while significantly expanding the available spectral range or wavelength options of conventional NIR and SWIR sources.
