Embodiment Construction

[0070] figure 1 The LED retrofit lamp 1 according to the first embodiment is shown in plan view. The LED retrofit lamp 1 is here intended to replace a conventional incandescent bulb with a screw base and therefore has an outer profile which, at least in its basic form, approximately reproduces the profile of a conventional incandescent bulb (see also image 3 ). The LED retrofit lamp 1 has a housing 2 into which an LED module 3 is inserted. The LED module 3 has an aluminum heat sink 4, on the upper side or front side 5 shown, an aluminum alloy with an eight-sided outer contour is fastened. 2 o 3carrier6. The carrier 6 is equipped with light sources in the form of light emitting diodes 7 . The light-emitting diodes 7 light up in the upper half of the space, ie in this illustration along the main direction of illumination beyond the frame. The carrier 6 has a central hole, through which a cable guide element designed here as a cable channel 8 can be inserted tightly throug...

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.

Description

technical field [0001] The invention relates to a lighting device, in particular to an LED retrofit lamp or an LED module for a retrofit lamp. The invention also relates to a method for producing a lighting device. Background technique [0002] LED retrofit lamps or their light sources are typically operated with a safety extra low voltage (“Safety Extra Low Voltage”; SELV). To this end, LED retrofit lamps have a driver for driving the LED(s), which driver includes a voltage regulator for converting a supply voltage, for example from 230V to a voltage of approximately from 10V to 25V, typically a transformer. The power of a SELV driver is typically between 70% and 80%. For SELV equipment, in order to protect electrical equipment, an insulation distance of at least 5mm must be maintained between the primary side and the secondary side of the voltage regulator, so as to avoid electric shock to users caused by leakage current. In particular, overvoltage pulses of up to 4 kV ...
