LucidShape - Application - LEDs
The automotive lighting industry is undergoing a fundamental change in the design and development of headlamps, especially with the integration of LED applications and lenses. New features and applications within LucidShape helps you to manage new tasks and techniques with added support of LED sources and lens optics.
Model LEDs
- This graph above shows the relative luminous intensity versus the polar-angle from the vertical axis in degree for an Osram LED.
LucidShape offers different possibilities to model LEDs:
- LED libraries
- Ray files
- Complex model
- Point Light Source
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.
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.
