How tocalculate light beamspread

Fibre optic lighting provides an extremely flexible tool kit to light many different types of project in a myriad of ways. The RobLight Lux Calculator completes this kit with a tool that calculates the light output of RobLight luminaires with Light Generator and customised Fibre Harness.

Lux Calculator is available for installation on Window machines.  To install, simply double click on the downloaded file and follow the prompts.  Depending on your system set up you may receive messages to answer in line for your security policy.  Step by step guide

The Light Generator screen shows a Port Scan and Uniformity factor.  The Port scan is an indication of the relative light output of the generator into fibres as offset from the centre of the Common End (Polyconnector). For most RobLight  LED Generators the output is relatively uniform across most of the diameter, reducing the need for randomising to maintain uniformity.  For more fully filled harness, the Calculator will prompt for randomised common end and in some cases suggest contacting sales team for assistance.

Once installed and configured, the calculator will present a screen with 3 sections: Light Generator, Harness and Fitting.

For calculating outputs for multiple fitting types, simply select the tails sizes, lengths and fitting types in turn and note the outputs.

For registered users, the enhanced version of Lux Calculator provides some additional information and can generate IES files for selected configuration.
