LIGHT-EMITTING DIODE DEVICE

摘要

The inventive light-emitting diode device comprises a semiconductor light-emitting diode (1) provided with electric contacts (2) and fixed to a base (3) which is made of a high-thermal conductive material and provided with through locating holes (4), wherein said light-emitting diode (1) can be also glued with the aid of an electrically conductive glue to a metal layer (5) which covers the base and on which a pin assignment topology of the light-emitting diodes is formed. The device also comprises a lid (6) in the form of a focusing or another lens which is made of a transparent material and provided with a cavity (7) arranged on a surface connected to the base (3) and with pins (8) coinciding with the through locating holes (4) embodied in the base (3), wherein the cavity (7) of the lid covers the light-emitting diode with the electric contacts thereof and comprises a light-diffusing medium (9) containing particles of a light-conducting material and a luminiphore. The cavity (7) communicates with the environment via one or several through holes (10) embodied in the base (3) for filling the cavity with the light-conducting medium. Said invention makes it possible to improve the assembling processabilty of the light-emitting diode device, to increase the light efficiency and a radiation uniform distribution at the device output.
