Laminate type light-emitting diode device, and reflection type light-emitting diode unit

摘要

A laminate type light emitting diode device having excellent heat radiation performance and high output capability is provided. A plurality of reflection type light emitting diode units 10 each of which includes a light emitting diode 2 and a dichroic mirror 3 in a hollow metal holder case 5 having high thermal conductivity so as to face each other are joined to one another through joint members 4 formed of electrical insulating material, thereby constructing the laminate type light emitting diode device 100.
