Method and apparatus for test of LED brightness by illumination sensor

摘要

The present invention relates to a light emitting diode (LED) Brightness testing apparatus and testing method using the illuminance sensor, relates to a light emitting diode (LED) light-emitting diode (LED) Brightness testing apparatus and testing method using the illuminance sensor for checking whether the brightness of the light generated in the respective normal light emitting diode (LED) provided in the module. A light emitting diode (LED) is mounted, and a light emitting diode (LED) module 700 is provided with a number, the light emitting diode (LED) measurement device for measuring the brightness of each light-emitting diode (LED) provided in the module 700 (100 ), and; Wherein each light emitting diode measured (LED) giving read multiplexer scans the output resistance of the brightness (Mux) circuit 200 and; Wherein each light-emitting diode (LED) resistance meter to measure the resistance value (Meter) (300) and; A light emitting diode (LED) light is input to the brightness range of the normal conductance values in advance, the measured resistance value to the computer to determine a pass or poor conductance compared to the value of the normal range in terms of capacitance values (400) is configured. Accordingly, the present invention can improve the discrimination because the determination by using the photo sensor changes the light-emitting diode (LED) brightness into an electrical signal, the inspection specification (Spec), and can be easily changed, even if the corresponding, at a relatively low cost light emitting has the effect of diode (LED) can determine whether the normal brightness.
