。[Claims for Utility Model Registration] LED having a plurality of LEDs arranged in a dot arrangement
In an LED print head that is equipped with an array and emits light from the LEDs to form an image on a photosensitive surface, a dielectric material is disposed along the LED array and allows a portion of the light emitted from the LEDs to enter from the side and exit from the end surface. What is claimed is: 1. An LED print head comprising: a formed optical waveguide; and an optical sensor disposed at both ends or one end of the dielectric optical waveguide to detect light emitted from the end face of the dielectric optical waveguide.
