The luminous efficacy of a source is defined as the ratio oittedf the luminous flux em by the light source to the electrical power consumed.
The definition of LED light efficacy (luminaire efficacy) refers to the ratio of the initial total luminous flux emitted by the lamp to the power consumed under the declared use conditions of the lamp, in lm/W.
 
As far as light sources are concerned, light efficiency is a classic indicator. The emergence of each new light source is directly related to the higher light efficiency it achieves. In this way, light efficiency has become an important indicator of the performance of LED light sources without exception.
When both LED light sources and LED light use light efficiency as a performance evaluation index, we first understand the performance of LED lamps by analyzing the connotations and differences between the two, and use correct terminology to evaluate the light efficiency of LED light sources and LED lamps. efficacy.
 
"Light efficiency" is used to evaluate LED light sources, and "efficiency" is used to evaluate LED light. Both LED light source light efficiency and LED light efficacy indicate the efficiency of converting electrical energy into light energy. They are indicators that describe the energy-saving characteristics of lighting products, but their connotation is different.
