Equivalent Luminous Efficiency - A Normalization Index to Luminous Efficiency of Luminaries

The luminous efficiency do make four impact factors confused such as existing of dissipated light, ability for transmission of lighting sources, distortion of visual effects and different values of power choosing during the luminous efficiency comparison under its current definition. In this paper, the equivalent luminous efficiency was introduced based on the discussion of these factors which maintains the form of current definition of luminous efficiency while it sets the equivalent coefficient to make test results comparable under different measurement conditions, so as to be clear when we compare and evaluate the properties of energy-saving and luminescence of luminaries.
