Features of Led Reflector Design Software

SHAPE is intended for optical systems design, especially for lighting reflector design. Its features permit design of rotationally or cylindrically symmetric optical systems with mirror surfaces.

Two stages of optical systems design are supported by the program:

  1. Reflector synthesis: Calculation of the reflector shape according to a specified luminous intensity distribution curve of the light source and the light distribution of the system (illuminance of the working plane or a luminous intensity distribution curve). For example, lighting reflector design used for office building lighting equipment incorporates specified uniform illuminance on a working plane.
  2. Reflector simulation: Calculation of the light distribution of a system when the reflector shape and parameters of the light source are specified. For example, LED reflector design is used for a lighting fixture to calculate its light distribution.

SHAPE can be used for lighting reflector design with different types of light distribution. The luminous intensity distribution curve of the light source is set by the user or remains uniform on default.

A light source is presented as point, line or three-dimensional object (disk, sphere, cylinder, ellipsoid, or toroid).

Examples of point sources are light-emitting diode LED (for LED reflector design) and metal-halide lamp (HQI-TS), or sodium high-pressure lamp (SON-T) with transparent outer bulbs (for lighting reflector design). On the other hand, the same type lamps with frosted outer bulbs (SON-H, HQI-E) as well as fluorescent lamps (fluorescent straight bulbs and circular bulbs) are sources of finite dimensions.

The SHAPE optical systems design program has the following features:

  • the design method is based on precise solution of differential equations for reflectors using the concept of geometric optics;
  • the illuminated area can be partly shaded by reflector is taken into account;
  • coefficient of utilization of the system is calculated.

During the reflector simulation, it is possible to: 

  • use an arbitrary number of light sources;
  • specify arbitrary center coordinates of a light source, thus enabling estimation of the defocusing of the system;
  • represent the reflector profile in different coordinate systems (Cartesian, polar) or as a ray tracing function;
  • solve the problem under arbitrary ray-tracing function, which make it possible to estimate aberrations;
  • exclude from calculation incidental light on the calculated area directly from the light source.
