Model LEDs

LucidShape offers different possibilities to model LEDs:

LED libraries


LucidShape holds a large library of Osram and Lumileds LEDs. Following types are implemented:

Osram LEDs

 
  • 1mm LED
  • 3mm LED
  • 5mm LED
  • Argus
  • Chipled
  • Firefly
  • OvalLED
  • SmartLED
  • SMT with LENS

Each type holds different individual LEDs.

This graph above shows the relative luminous intensity versus the polar-angle from the vertical axis in degree for an Osram LED.

Lumileds LEDs

  • Batwing
  • Lambertian
  • SideEmitter

Again, each type holds different individual LEDs.

Ray file

The LED can also be simulated with a ray file.

Complex model

One can also picture a LED with a complex model.

LED Point Light Source Editor

You can create any arbitray LED light intensity distribution for point light sources with the LucidShape's LED Point Light Source Editor. The intensity can be entered in 5° steps. Optionally, one can enter different values in horizontal and in vertical direction.

Customize LEDs

You can also model your own LED. This simple model consist of a cone reflector, a spherical surface and a directional emitter, which represents a LED with Lens. The LED is either modeled with a lambert emitter on a disk (disk emitter) or on 5 planes forming a box shape (box emitter). The disk radius and the box size and the number of rays for the simulation can easliy be altered within the dialog box.

Applications

LED Beacon Light

This application shows a LED ring with an outer lens for a beacon light. You can choose the number and the position of the LEDs, and the geometry of the outer lens. The optical contours of the lenses can either be of type elliptical, hyperbolical, FF inner and FF outer. The lens radii, lens height, focus radii, sweep angles can also be altered.


After the simulate button is pressed, one can see the light intensity distribution with a Candela sensor.
