Illuminating lamp for use as e.g. table lamp, has light flow limiter for laterally delimiting light flow emission cone of optic, and diffuser placed in emission cone and intercepting light flow from limiter for diffusing light flow

摘要

The lamp (100) has a LED diode (1) fixed on a circuit board (2) and equipped with focusing optic for forming a light flow with different geometry in a conical volume (C). A support (4) is fixed to a heat conductive metal plate (3) of the board for ensuring direct heat conductive contact. The plate is made of aluminum, and the support is made of better heat conductive material. A light flow limiter (6) laterally delimits a light flow emission cone (CFL) of the optic. A diffuser e.g. web, is placed in the emission cone and intercepts the light flow from the limiter for diffusing light flow.
