Abstract
An LED lighting device, in particular an LED retrofit lamp, comprising a light-emitting means (2) having at least one LED (16) and a lampholder (1) for accommodating the light-emitting means (2), and at least one elastic element (12), which braces the light-emitting means (2) in the lampholder.
Claims8
An LED lighting device comprising:
- an elongated light-emitting means comprising:
- an elongated heat sink mount having a longitudinally extending lateral bearing edge projecting outwardly and extending longitudinally;
- an elongated electronic circuit board mounted longitudinally to the elongated heat sink mount;
- and
- a plurality of LEDs electrically mounted longitudinally to the elongated electronic circuit board;
- and
- an elongated lampholder comprising:
- a first elongated flank;
- a second elongated flank;
- and
- an elongated rail base, wherein a first longitudinal edge of the elongated rail base is connected to a first longitudinal edge of the first elongated flank and wherein a second longitudinal edge of the elongated rail base is connected to a first longitudinal edge of the second elongated flank so that the first and second elongated flanks and the elongated rail base form an elongated U shape,
- wherein a second longitudinal edge of the first elongated flank has an elongated latching tab projecting inwardly;
- and
- an elongated elastic element mounted on the first elongated flank between the elongated latching tab and the elongated rail base,
- wherein the elongated light-emitting means and the elongated lampholder are shaped so that, when the elongated light emitting means is fully mounted into the elongated lamp holder, the elongated light-emitting means fits into the elongated U shape of the elongated lampholder with the longitudinally extending lateral bearing edge fitting between the elongated latching tab and the elongated rail base and with the elongated elastic element exerting a pre-tensioning force on the elongated heat sink mount of the elongated light-emitting means directed toward the second elongated flank of the elongated lampholder to clamp the elongated light-emitting means between the elongated elastic element and the second elongated flank.

An LED lighting device comprising:
- a light-emitting means comprising:
- a circular heat sink mount disk having a bearing edge projecting circumferentially outwardly, the circular heat sink mount disk having a projection extending from a bottom surface of the circular heat sink mount disk;
- a ring-shaped electronic circuit board mounted to a top surface of the circular heat sink mount disk;
- and
- a plurality of LEDs electrically mounted in a circle to the ring-shaped electronic circuit board;
- and
- a lampholder comprising:
- a curved flank;
- and
- a circular base plate, wherein a portion of a circumferential edge of the circular base plate is connected to a first edge of the curved flank with the curved flank extending substantially perpendicular from a top surface of the circular base plate, the circular base plate having a recess in the top surface shaped and positioned so as to mate with the projection extending from the bottom surface of the circular heat sink mount disk when the light emitting means is fully mounted into the lamp holder,
- wherein a second edge of the curved flank has a latching tab projecting radially inwardly;
- and
- an elastic element mounted on the curved flank between the latching tab and the top surface of the circular base plate, the elastic element positioned to exert a pre-tensioning force on the bearing edge of the circular heat sink mount disk of the light-emitting means directed toward a center of the circular base plate when the light emitting means is fully mounted into the lamp holder,
- wherein the light-emitting means and the lampholder are shaped so that the light-emitting means fits into the lampholder with the bearing edge fitting between the latching tab and the top surface of the circular base plate when the light emitting means is fully mounted into the lamp holder.
