METHOD AND DEVICE FOR LED MEASURING INSTRUMENT BASED ON PULSE OF DIVISION

摘要

PURPOSE: A method and a device for measuring the optical characteristics of a division pulse based LED module are provided to effectively achieve an optical characteristic measurement by effectively reducing and enhancing the optical characteristic measurement time. CONSTITUTION: A method of measuring the optical characteristics of a division pulse based LED module is as follows. A light measurer(30) is set to be able to perform a light measuring operation by a trigger command. A command to generate division pulse every given pulses and to generate a trigger command is input to a micom through a computer(40). A command to rotate a motor with a motor controller is issued from the computer and the encoder attached to the motor receives pulse correspond ing to the angle change according to the rotation of the motor to transfer it to the motor controller. The controller divides pulse every given pulses to generate division pulse. The division pulse is converted into a trigger signal and is transmitted to the light measurer. If the trigger signal is supplied, the light measurer measures optical characteristics according to the trigger signal.
