PROJECTOR DEVICE, MULTILAYER LIGHT-EMITTING DIODE DEVICE, AND REFLECTIVE LIGHT-EMITTING DIODE UNIT

摘要

Disclosed is a multilayer light-emitting diode device which is excellent in heat dissipation and can be formed to have high output. Specifically disclosed is a multilayer light-emitting diode device (100) formed by connecting a plurality of reflective light-emitting diode units (10) using connecting materials (4) which are made of an electrically insulating material. Each reflective light-emitting diode unit (10) is obtained by arranging a light-emitting diode (2) and a dichroic mirror (3) opposite to each other in a hollow holder case (5) which is made of a metal having high thermal conductivity.
