Optical probe led chip module for biostimulation and method of manufacturing the same

Abstract

A probe-type light-emitting diode (LED) chip module for biostimulation includes: an LED chip, a substrate supporting the LED chip, an optical waveguide collecting light emitted from the LED chip; and an insulator coupling the substrate with the optical waveguide and providing insulation from outside. The optical waveguide includes: a body extending from one end facing the LED chip with a cylindrical shape; a variable layer having a diameter decreasing gradually from the other end of the body; and a probe extending from the end of the variable layer and having a diameter equivalent to that of an optical fiber. The probe-type LED chip module for biostimulation may be manufactured with a small size to have superior portability and applicability.
