Problems solved by technology

However, this is currently only possible at relatively high manufacturing costs
Especially when, for example, retrofit lamps are to be used to replace incandescent lamps in the entire house, the costs increase considerably, so that only parts of the luminaires can be replaced or replaced completely
In this way, a large amount of energy is wasted not only for a single house, but also worldwide

Embodiment Construction

[0027] In the following text, the same reference numerals are used for identical and functionally identical elements.

[0028] figure 1 A circuit diagram of a first exemplary embodiment of a lighting device according to the invention is shown schematically. As a voltage source, for example an AC voltage source U capable of supplying an AC voltage with an amplitude of 220 V is used V . at the AC voltage source U V On the one hand, the filament GF is connected in series, and on the other hand, two LEDs, LED1 and LED2, are connected in antiparallel. The area 10 marked with dotted lines shows which components can preferably be arranged on the printed circuit board.

[0029] As can be seen in the figure, the filament GF is not arranged on the circuit board 10 . The outline 12 marked by a dotted line indicates that the filament GF can be operated in the same atmosphere as the LED, such as the protective gas known from conventional incandescent lamps, which preferably contains a...

Abstract

The invention relates to a lighting means (16) having at least one LED (LED1, LED2), wherein the lighting means (16) further comprises at least one filament (GF), the at least one filament (GF) beingconnected in series to the at least one LED (LED1, LED2).

Description

technical field [0001] The invention relates to a lighting device with at least one LED. Lighting devices with LEDs are characterized by a long lifetime and high efficiency. In order to enable it to be operated also in conventional lamp sockets, so-called retrofit lamps are available on the market, which externally resemble conventional incandescent lamps, but which use LEDs as light sources inside. Background technique [0002] Since the introduction of LEDs for retrofit lamp production, great improvements have been made in terms of efficiency, color performance, and lifetime. However, this is currently only possible at relatively high production costs. Especially if, for example, retrofit lamps are to be used to replace the incandescent lamps in the entire building, the costs are significantly increased, so that only parts of the luminous means can be replaced or replaced completely. In this way, a large amount of energy is wasted not only for a single house, but also w...
