LED-BASED LIGHTING FITTINGS FOR SURFACE LIGHTING, WITH IMPROVED HEAT DISSEMINATION AND TECHNOLOGY

摘要

1. A lighting device comprising:! a heat sink having a first surface; ! an LED circuit board having a second and third opposing surfaces, of which the second surface is located on the first surface of the heat sink, and the third surface has at least one LED light source located on it; ! an integrated element with a lens having a transparent upper wall arranged so as to receive light that emits at least one LED light source; ! a pressure transmitting element having a support structure extending generally in the direction from the LED circuit board to the transparent upper wall of the integrated element with a lens and further having a pressure transmitting surface connected to the support structure, the support structure defining the hole, the pressure transmitting surface being located on a third surface of said LED circuit board in the vicinity of the LED light source; and! optical element located in a hole bounded by the supporting structure of the pressure transmitting element,! in which the integrated element with the lens is connected by squeezing with the pressure transmitting element, so that the force applied to the integrated element with the lens is transmitted through the pressure transmitting element to the pressure transmitting surface so as to press the LED circuit board to the first surface of the heat sink, so that provide heat transfer from the LED circuit board to the heat sink. ! 2. The lighting device according to claim 1, in which the integrated
