The purpose of the task is to calculate the profile of the reflector and ensure coincidence with the parabola. The light distribution is given in the analytical form of the corresponding distributions obtained from the parabolic light reflector.

Specify luminous intensity distribution (LID) of the light source in the form:

**I(γ) = (1 - cos(γ)) / 2**(cardioid)

and profile as parabola with focus F = 0.5 m**γ _{s} = 180^{o}, γ_{f} = 90^{o}**

Height of the light center:**h = 1 m**

Illuminance distribution on the working plane from paraboloid:

Rotational symmetry**E = (1+x ^{2})^{-3}**

Cylindrical symmetry **E = (1+x ^{2})^{-2}**

Criteria for calculating the parabolic mirror:

- when
**γ = 90**the value of the coordinates of the reflector^{o}**R = 1 m** - reflected rays should be strictly vertical
**α = 0**^{o}
