Optical simulations – what are they?

The latest capabilities of simulation programs include various types of optical simulations, commonly referred to as light simulations, such as in-car headlights, which are now largely illuminated by modern optical systems  with an LED light source. is an LED.

When a driver gets into his car, he doesn’t think about the hue or evenness of the illumination  which his vehicle is equipped with. However, it is worth taking a closer look at the different types of illumination that the simulation area offers today.   These  mainly include communication devices and HUB-type chargers, illuminated decorative frames, cabin function lighting, as well as a whole range of other accessories found in cars.


The direction of development of computer analysis is determined by the use of engineering programs to simulate light luminance phenomena. The platform on which such simulations are performed is an integrated module that is fully compatible with CAD programs. This combination of engineering tools significantly increases productivity when designing complex mechanical-optical components. This configuration also allows seamless switching between modules, which in turn reduces working time.

A huge toolkit, as well as a sizable database contained inside the module, provides the opportunity to simulate many optical phenomena. In addition to this, these tools provide an opportunity to solve complex backlighting problems in many types of devices manufactured by our company, including HUB chargers.

What do the simulations of light provide us with?

  • Finding and solving many problems early in the design of optical systems;
  • Reduced working time at the product development stage;
  • Learning about phenomena that are sometimes impossible to study experimentally;
  • Optimizing the design of optical systems;
  • Ability to visualize light rays, luminance and light intensity;
  • Ability to show homogeneity results (uniformity of illumination) in the form of graphs or contour maps;
  • The ability to measure the chrominance (color) of light.

What do we simulate?

  • Ray Tracing
  • Ambient Light
  • Light Guide, Light Pipe, Fiber Optic
  • Illumination Pictograms
  • LED Status Illumination

What does the mechanical-optical system mean?

The mechanical-optical system is characterized by a compact structure of elements that are both transmitters of light and those that reflect or absorb this light. Such an arrangement is designed to guide the light stream in the right way and then illuminate a given object, space or symbol with the right intensity and homogeneity.

Simulation versus reality

Simulations should be reflected in reality during experimental studies. Illumination tests are carried out in a specially darkened room. The results in the form of a luminance image in the real environment are recorded on a special LMK camera (Luminanz Messung Kamera).  After the analyses, the experimental results are compared with those from the simulations. Studies in correlation with simulation show high convergence with each other.
