So ist ein Kühlkörper oftmals in der Leuchte angeordnet und entsprechend klein dimensioniert, da der Platz in der Leuchte für die Elektronik zum Betrieb der Leuchtdioden benötigt wird.In A retrofit lamp, LEDs are often under a milky Dome operated from plastic, which modeled on the shape of a light bulb is. Here, there is a problem to dissipate the heat suitable. So is a heat sink often arranged in the luminaire and dimensioned accordingly small, since the place in the light for the electronics are needed to operate the light-emitting diodes.
Auch ist es ein Nachteil, dass für einen Benutzer oder einen Kunden eine stromsparende Retrofit-Lampe im Betrieb nicht von einer herkömmlichen Glühbirne unterscheidbar ist.Also it is a disadvantage that for a user or a customer a power-saving retrofit lamp not in operation from a conventional one light bulb is distinguishable.
Die Aufgabe der Erfindung besteht darin, eine Retrofit-Leuchte anzugeben, die für einen Betrachter als solche erkennbar ist und eine verbesserte Wärmeableitung aufweist.The The object of the invention is to provide a retrofit lamp, the for a viewer is recognizable as such and improved heat dissipation having.
Diese Aufgabe wird gemäß den Merkmalen der unabhängigen Ansprüche gelöst. Weiterbildungen der Erfindung ergeben sich auch aus den abhängigen Ansprüchen.These Task is performed according to the characteristics of independent claims solved. Further developments of the invention will become apparent from the dependent claims.
Zur Lösung der Aufgabe wird eine Leuchte vorgeschlagen
- – mit einer Platine aufweisend mindestens eine Leuchtdiode,
- – wobei die mindestens eine Leuchtdiode so auf der Platine angeordnet ist, dass diese als einzelne Lichtquelle von außen auch durch eine milchige oder teilweise opake Kuppel wahrnehmbar ist.
- Having at least one light emitting diode with a circuit board,
- - Wherein the at least one light-emitting diode is arranged on the board, that this is perceptible as a single light source from the outside by a milky or partially opaque dome.
Somit kann ein Betrachter der Leuchte sofort erkennen, dass es sich um eine effiziente Leuchte mit moderner Technologie handelt.Consequently a viewer of the luminaire can immediately recognize that it is an efficient luminaire with modern technology.
Hierbei sei angemerkt, dass es sich bei der Leuchtdiode um jedwedes Halbleiterleuchtelement bzw. um jeden Halbleiterstrahler handeln kann.in this connection It should be noted that the light-emitting diode is any semiconductor light-emitting element or can act around each semiconductor emitter.
