Abstract

W urządzeniu oświetlającym z płytką (40) z diodami LED zawierającym obudowę (5), do której jest przymocowany klosz (20) osłaniający płytkę (40) z diodami LED i co najmniej jeden element osadczy (60) z elementami kontaktowymi (61) umożliwiającymi przyłączenie płytki (40) z diodami LED do zewnętrznego źródła zasilania, obudowa (5) posiada radiator (10), odprowadzający ciepło, z powierzchnią stykową, do której przylega płytka (40) z diodami LED. Wspomniana płytka (40) z diodami LED zawiera metalową dolną warstwę ekranującą, którą płytka (40) z diodami LED, jest zwrócona do powierzchni stykowej, od której dolna warstwa ekranująca jest odizolowana, i co najmniej jedną metalową dodatkową warstwę ekranującą, które są ze sobą połączone za pomocą łącza elektrycznego i między którymi znajduje się co najmniej jedna wewnętrzna warstwa z obwodami elektrycznymi łączącymi diody LED, z układami zasilającymi i układami sterującymi, przy czym metalowa dolna warstwa ekranująca jest połączona dodatkowo za pomocą równoległego układu RC z jednym z biegunów układu zasilania płytki (40) z diodami LED, a metalowa dodatkowa warstwa ekranująca jest połączona za pomocą równoległego układu RC z pozostałym biegunem układu zasilania płytki.In a lighting device with a plate (40) with LED diodes comprising a housing (5) to which a cover (20) is attached covering the plate (40) with LED diodes and at least one mounting element (60) with contact elements (61) enabling the connection of the plate (40) with LED diodes to an external power source, the housing (5) has a heat sink (10) for dissipating heat, with a contact surface to which the plate (40) with LED diodes is attached. Said LED plate (40) comprises a metal lower screening layer, with which the LED plate (40) faces a contact surface from which the lower screening layer is insulated, and at least one additional metal screening layer, which are connected to each other by means of an electrical connection and between which there is at least one inner layer with electrical circuits connecting the LEDs to the power supply circuits and the control circuits, wherein the metal lower screening layer is additionally connected by means of a parallel RC circuit to one of the poles of the power supply circuit of the LED plate (40), and the metal additional screening layer is connected by means of a parallel RC circuit to the remaining pole of the power supply circuit of the plate.
