Claims (1)
- 自動車用途において照明装置を駆動するシステムであって、
第1回路、第2回路、及び照明装置を有し、
前記第1回路は、オン状態で電力を前記第2回路へ供給し、オフ状態で電力を前記第2回路へ供給せず、前記第2回路は、エネルギーを保持するよう構成される誘導回路を有し、前記第1回路は、自動車用電源へ結合されるように配置される正極電位端子及び負極電位端子へ結合され、前記負極電位端子は、自動車用接地電位へ結合されるように配置され、
前記第2回路は、前記オフ状態で、前記第2回路に保持されているエネルギーを前記照明装置へ供給し、
前記照明装置は、陽極及び陰極を備える発光ダイオード又は有機発光ダイオードを有し、前記照明装置及び前記自動車用電源は、互いから電気的に減結合されるか、又はガルバニック絶縁され、
前記照明装置は、該照明装置の前記陽極へ接続されるスラグを有し、該スラグは、熱抵抗を減らすために、絶縁層が介在することなしにヒートシンクに直接取り付けられ、それにより、前記自動車用接地電位へ結合されるように配置される、前記陽極から前記スラグを介して前記ヒートシンクへの電気的な接続が存在する、システム。
