Phlox LED illumination

High intensity and uniformity LED lights

Phlox lights are lit by a linear array of LEDs using a light pipe structure to redirect the light to the surface of the diffuser. The CO2 laser etching process of the diffuser allows a combination of refraction and diffusion to improve backlight luminance.

This allows up to 80% of the injected light to be re-emitted from the surface with a fan angle of 30°. Thanks to mathematical modeling, Phlox backlights emit light in a deterministic and perfectly controlled manner.

Reasons to choose Phlox lights

Exceptional luminance and uniformity

Phlox illumination reach very high luminance values up tio 130.000 cd/m², depending model and actual size. Thanks a fan angle reduced to 30°, most of the light is directed to the camera sensor. Therefore the degree of efficiency is higher as with other Lambertian sources. The devices provide a uniformity of over 95% (+/-10%): Phlox delivers each backlight with a data and distribution chart that specifies uniformity and luminance.

Minimised chromaticity shift

The chromaticity shift is typically smaller than 10% over the complete LED lifetime. Recalibration (white balance) of the system is therefore generally not necessary, even for colour sensitive applications.

Extended lifetime

Phlox illumination boasts a very long expected lifetime of 50.000 hours (and more!).

Available in a variety of sizes and colours

Phlox covers a broad range of applications by providing several housing sizes with each model. Often, there is also a choice between different colours.

Industry grade housing

IP65 rating permits the use in harsh environments without the need for additional housing. This reduces the costs but also allows for a more flexible integration.
