Abstract:
The invention relates to an illumination device (1) comprising a first heat sink (5), a carrier substrate (8) populated on the front side thereof by at least one light source (9), in particular a light-emitting diode, and the back side thereof being attached to the first heat sink (5), and comprising a second heat sink (10) disposed substantially in front of the carrier substrate (8), wherein the at least one light source (9) is disposed outside of the second heat sink (10; 32).
Abstract:
The lighting device (21) has a cooling body (2) with at least one receiving area (5), each area holding one printed circuit board (3), and a printed circuit board (3) introduced therein, said printed circuit board (3) having at least one light source (12) on a front face (10) and being at least in thermal contact with the cooling body (2) on a rear face (16). Each printed circuit board (3) has at least one rotational locking means that is engaged with a counter rotational locking means of the receiving area (5) for said printed circuit board. The method is used for assembling a lighting device (21) and has at least the following steps: inserting the at least one printed circuit board (3) into the corresponding receiving area (5) by an essentially linear feeding movement; and rotating the printed circuit board (3) against the cooling body (2).
Abstract:
The invention relates to a lighting device (11) having at least one heat sink (5) for cooling at least one light source, wherein the at least one heat sink (5) comprises one or more at least bent sheet metal parts, in particular punched sheet metal parts. The invention relates to a method for producing a heat sink (5) of the lighting device (1), wherein the method comprises at least the following steps: blanking radially extending clearances (17) at an edge of a sheet metal and bending up the segments (14) that remain between the clearances (17) at a central contact area (12). The invention further relates to a different method for producing a lighting device (1), wherein the method comprises at least the following steps: Inserting a driver housing (6) into the heat sink (5); and/or fixing a carrier substrate (2) to the contact area (12).
Abstract:
The invention relates to a lighting device (1) having at least one body (4), particularly a heat sink, having an outer contact surface (24) and a light source carrier (6), particularly an LED carrier pressed onto the contact surface by means of at least one pressing element (43), wherein the pressing element can be attached to the lighting device (1) by means of at least one rotary motion. Said method permits the production of a lighting device with at least one body having a contact surface for a light source carrier, wherein the light source carrier is pressed against the contact surface of the lighting device by means of rotating a pressing element.
Abstract:
The invention relates to a lighting device having at least one at least partially transparent cover which covers at least one light source, in particular a light emitting diode, so that there is a hollow chamber between the at least one light source and the cover, and further has at least one cooling body structure, which is at least partially located in the hollow chamber and/or at least partially recessed in the cover.
Abstract:
The invention relates to a light bulb (1), at least comprising one cooling body (2) that carries at least one light source (10), in particular a semiconductor diode, especially an LED, and an at least partially light-permeable cover (11) attached to the cooling body (2) for the at least one light source (10), wherein the cover (11) has a wall thickness (d), that tapers, at least in sections, as the distance thereof from the cooling body (2) increases.
