Lighting apparatus
View Patent ↗A lighting apparatus may include an electrically conductive housing, in whose interior at least one light source and at least one electromagnetic radiation-emitting circuit component configured to operate the at least one light source are arranged; and an electrically conductive cover configured to cover the at least one circuit component; wherein the cover and the housing are electrically connected to one another.
1. A lighting apparatus, comprising: an electrically conductive housing, in whose interior at least one light source and at least one electromagnetic radiation-emitting circuit component configured to operate the at least one light source are arranged and wholly encompassed; and an electrically conductive cover configured to immediately and wholly cover the at least one circuit component; wherein the cover and the housing are electrically connected to one another;
wherein the cover comprises an optical element configured to guide the beam of light emitted by the light source;
wherein the optical element comprises a reflector.
2. The lighting apparatus as claimed in claim 1 , wherein the at least one electromagnetic radiation-emitting circuit component is configured to emit electromagnetic radiation having a frequency of approximately 100 kHz or more.
3. The lighting apparatus as claimed in claim 1 , wherein the reflector has a metal plating.
4. The lighting apparatus as claimed in claim 1 , wherein reflector is produced from metal.
5. The lighting apparatus as claimed in claim 1 , wherein the reflector is held in an electrically conductive manner on the housing.
6. The lighting apparatus as claimed in claim 1 , wherein the reflector is connected to the housing by means of an electrically conductive adhesive.
7. The lighting apparatus as claimed in claim 1 , wherein the reflector is connected to the housing by means of an electrically conductive, mechanical connecting element.
8. The lighting apparatus as claimed in claim 1 , wherein the housing is produced from metal.
