THE LIGHT INTENSITY MEASURING DEVICE HAVING OPTICAL FIBER

摘要

A light intensity measuring device having optical fibers according to an embodiment of the present invention comprises: a plurality of sockets having protrusions formed on upper ends thereof to prevent light emitted from a plurality of light emitting elements from escaping to the outside; a plurality of first optical fibers to penetrate the sockets in a vertical direction and receive the light emitted from the light emitting elements; second optical fibers to receive the light received by the first optical fibers; a connection unit to connect the first optical fibers and the second optical fibers; a sensor unit to measure intensities of the light received through the second optical fibers; a control unit to control operation of the sensor unit; and a calculation unit to calculate an average of a plurality of intensities of the light measured in the light emitting elements after excluding the largest and the smallest intensity.
