Standard LED with coupled POF pigtails

led with pigtail

POF coupled LED modules are a good solution, if high optical power is required in hard-to-reach places, such as inside an apparatus or in a remote outdoor location, without the possibility of directly mounting the LED and its power supply there.

The module generates optical powers of up to 10 mW at the POF end face with only 20 mA LED current thanks to a high coupling efficiency between LED and POF. We manufacture modules with other coupled optical fibers (POF or fiber optic) upon request.

We generally do not guarantee the achievable data rate of the modules since the LED modules with POF pigtails are intended for lighting or sensor applications.

Power LED with coupled POF – Pigtail

PowerLED coupled to 1mm POF

In special applications, the maxim possible optical power from LED into a 1mm standard POF is required without the coupling efficiency or power consumption of the module being a factor. In these case, LED modules are available in which the POF is butt-coupled to a40mil PowerLED. The highest optical power is coupled intp a POF with a diemeter of 1mm, if its end face touches a 40mil PowerLED with the same area.

The coupling efficiency is significantly lower compared to a module with beam shaping like the micro parabolic reflector, so that a high heat loss occurs. Up to an LED current of 200mA, this can be dissipated via an enlarged and thermally very well connected heat sink. Flags made of copper foil can be additionally attached to cope with the heat loss when operating at 350mA.

PowerLED Modules for thicker fibers

LED module for SL POF

We developed primarily the PowerLED module for coupling to thicker (3mm – 6mm) plastic optical fibers for use in conjunction with sidelight fibers. Of course, optical fibers with a similar diameter can also be coupled.

RGB – LED Emitters

A new development of DieMount are RGB LED spotlights with 3 different colored 500µm LED chips. Depending on which LED is electrically controlled, these modules shine in the corresponding wavelength. We can realize light modules with changing color by suitable control system. The photos below show the same module with different color control.
