METHOD OF INSPECTING MIXED LIGHT STATE OF SIMULATION LIGHT EMITTING DIODE LIGHT SOURCE

摘要

PURPOSE: A method for detecting a mixed light state of a light emitting diode light source simulation is provided to primarily detect a plurality of light bars and a LED unit including the same without considering of a light uniform role after the LED light bar penetrate a diffusion sheet. CONSTITUTION: A method for detecting a mixed light state of a light emitting diode light source simulation is as follows. An exclusive diffusion light field profile with respect to a LED unit penetrating one or more diffusion sheets is taken(S101). The diffusion light field profile is became a reference diffusion light field profile by a normalization(S102). Coordinates of each unit of common detection images and light intensity information corresponding to the coordinates are detected(S104). Images of a light emitting diode light source simulation are obtained by applying the reference diffusion light field profile to each LED unit based on the coordinates of each unit and light intensity information corresponding to the coordinates(S105).
