  1. Lichtstärke
    • Iv (Ω) = dΦV / dΩ
    • [lm/sr] = [cd]
  2. Spektraler Lichtstrom
    • ΦV (λ) = Km * V(λ) * Φe(λ)
    • Km = 683lm/W
  3. Spektraler Strahlungsfluß
    • Φe(λ) = dΦe / dλ
    • [W/nm]
  4. Leuchtdichte
    • LV(Ω) = dIV / dAS = dΦ / dΩ * dAS
    • [cd/m²]
  5. Beleuchtungsstärke
    • EV = dΦV / dAD
    • [lm/m²] = [lx]
  6. Photometrisches Grundgesetz
    • ΦV = LV * AS * ΔΩS = EV *AD = EV * ΔΩS * r²
    • => LV *AS = EV * r²
  7. Großer Lambertstrahler
    • Iv(α) = LV * AS = LV * AS,0 * cos(α) = IV,0°
    • Lichtstärke IV = konstant
    • Fläche A hängt von cos ab
  8. Kleiner Lambertstrahler
    • Iv(α) = LV * AS = LV * AS,0 * cos(α) = IV,0°
    • LV(α) = LV,0° = konst.
    • keine winkelunabhängige IV mehr
