Abstract

The lamp has LEDs (1) assembled on a semi-circle shaped circle segment plates (2) that are arranged on a mounting plate (3). Each LED is displaced on respective circle segment plate from its vertical mounting position into its definite operating angle for adjusting radiation angles. Radiation angle of the lamp results from an angle of an edge extreme LED and from an individual radiation angle of engaged LED.

Description

Die Erfindung betrifft das einstellen des Abstrahlwinkels einer LED-Lampe aus mehreren Leuchtdioden.The Invention relates to adjusting the emission angle of an LED lamp from several LEDs.

Herkömmliche LED-Lampen haben eine bis mehrere senkrecht montierte Leuchtdioden. Da gängige Leuchtdioden in den Durchmessern von 3 bis 5 mm nur über einen geringen Abstrahlwinkel von 10 bis 20 Grad verfügen, ergibt sich auch für solche LED-Lampen nur ein begrenzter Abstrahlwinkel.conventional LED lamps have one to several vertically mounted LEDs. As usual LEDs in the diameters of 3 to 5 mm only one low beam angle of 10 to 20 degrees, also results for such LED lamps only a limited angle of radiation.

Die Erfindung wendet bogenförmige Kreissegmente an, auf der einzelne Leuchtdioden der LED-Lampe in definierte Abstrahlwinkel eingestellt werden können.The Invention applies arcuate Circular segments on which individual LEDs of the LED lamp in defined beam angle can be adjusted.

Durch diese Vorkehrung ist es möglich flexibel, sowohl sehr enge Abstrahlwinkel, mit hoher Lichtintensität, als auch breite Abstrahlwinkel, mit relativ gleichbleibender Ausleuchtung, für die gesammte LED-Lampe zu realisieren.By this precaution makes it possible flexible, both very narrow beam angle, with high light intensity, as well wide beam angle, with relatively constant illumination, for the to realize the whole LED lamp.

Die Erfindung berücksichtigt hierbei auch den Fertigungsprozess von automatischen Bestückungsautomaten, bei der die Bauteile senkrecht eingebracht werden, da die LEDs erst nach dem Bestücken in ihren definierten Abstrahlwinkel mechanisch verbracht werden.The Considered invention here also the production process of automatic placement machines, in which the components are introduced vertically, since the LEDs only after loading be spent mechanically in their defined beam angle.

Zur Erhöhung der Packungsdichte von Leuchtdioden auf der Montageplatte können die Kreissegmentscheiben einseitig oder beidseitig abgeschnitten sein, sowie mehrteilig aufgebaut sein, um die Kreissegmentscheiben auch ineinander zu verzahnen.to increase The packing density of light emitting diodes on the mounting plate can be the circular segment discs cut off on one or both sides, and constructed in several parts be to interlock the circular segment discs also into each other.
