Definitions
- the present application relates to a lighting device with at least one base, in which a light source can be used.
- the base has electronic connections for supplying the luminous means, wherein an electrical or electronic ballast device is provided in the lighting device, which ensures a suitable electrical supply of a fluorescent lamp.
- lighting fixtures in the form of lamp sockets have electrical or electronic ballasts, such as transformers, to provide suitable voltage for incandescent lamps, including halogen lamps.
- LEDs light-emitting diodes
- DE 10 2004 044 166 B4 discloses an explosion-proof luminaire with light-emitting diodes as the light source, wherein the light-emitting diodes are supplied by a suitable electronic ballast.
- lighting means which essentially have the shape of an incandescent lamp, and are used in a conventional incandescent lamp holder, but in which light is generated by means of LEDs.
- LEDs for a ballast in the lamp itself is provided in such lamps.
- an LED light source (light-emitting diode bulbs) is known, with which a fluorescent lamp can be replaced, the supply of the LED light source via a cable set, connected to the socket with an on-board voltage source of a motor vehicle can be so that in the LED bulb only a diode must be provided, which is a destruction of the lighting diodes in case of erroneous confusion of polarity when inserting the LED bulb can prevent in the socket.
- the LED lighting means may comprise switching means with which the LEDs can be switched on or off individually, in pairs or in groups.
- Object of the present invention is to improve a generic lighting device to the effect that a simple change between, for example, fluorescent lamp and an LED light source with a number of LEDs is possible without electrical or mechanical adjustments of the lighting device are necessary.
- a corresponding LED illuminant can be used according to the invention without mechanical or electrical or electronic adjustments in the lighting device, which is otherwise suitable with the electrical or electronic ballast for one or more fluorescent lamps. That is, the lighting device can be optionally used with fluorescent lamps or a corresponding LED lighting means, without further measures on the Vorschaltvorraum, the wiring or switching by using a switching device or the like.
- LEDs are used, which are connected in series, and their current value substantially corresponds to a lamp current during operation of the lighting device with fluorescent lamp or fluorescent lamps.
- the AC input voltage is rectified and converted by means of boost converter to a regulated DC voltage (so-called DC link voltage).
- the ballast has a transistor half-bridge and an LC series resonant circuit wherein the fluorescent lamp is connected in parallel with the capacitor of the LC series resonant circuit.
- the above-mentioned intermediate circuit voltage is converted in a push-pull manner into a square-wave voltage having a constant frequency with such a transistor half-bridge.
- Today common switching frequencies of modern ECGs are in the range of 20kHz to 60kHz.
- a system of constant voltage and constant frequency becomes a system with constant current, which corresponds to the principle of a Boucherot circuit.
- the LED illuminant can have a bridge rectifier or such a bridge rectifier is assigned to the LED illuminant.
- a not yet ignited fluorescent lamp has a high ohmic resistance in the range of a few 100 kQ.
- the corresponding LC resonant circuit thus first idles, so that the voltage on the capacitor of the resonant circuit increases until the fluorescent lamp has ignited and then loaded the resonant circuit with a resistor in the order of several 100 ⁇ .
- This resistance depends on the lamp type.
- a switching frequency of the aforementioned transistor half-bridge is changed to near a resonance frequency during the starting phase. After the fluorescent lamp has ignited, this frequency is kept constant and the lamp current is almost constant regardless of the lamp type.
- the series resonant circuit is already loaded in such a starting phase when using the LED illuminant, so that no high voltages arise at the corresponding capacitor of the resonant circuit and the resonant circuit immediately acts as a current source.
- This is realized in a simple manner in that the voltage across this capacitor of the resonant circuit is rectified with said bridge rectifier and this DC voltage is loaded directly with the corresponding number of LEDs connected in series.
- diodes are preferably used for the bridge rectifier, which are adjusted with respect to their Sperrverzugsterrorism to the switching frequency of the ballast.

- the voltage of the capacitor so that it corresponds approximately to the burning voltage of a fluorescent lamp.
- a thyristor Klemmschltung can be assigned as a protection circuit to the LED lighting between LEDs and bridge rectifier.
- Such a thyristor clamping circuit is also called a thyristor crowbar.
- Possible component faults of the LEDs are alloying and thus short-circuiting of the LED or the LED becomes high-impedance, for example, due to an interruption of the bond wires.
- the ballast behaves in a relatively large load range as a constant current source.
- the short circuit of one or more of the series-connected LEDs is usually not critical.
- An interruption of an LED means at the same time an interruption of the entire load circuit of the corresponding resonant circuit.
- the result is an increase in the output voltage of the ballast to values of several 100 Vrms. This high voltage is cut off in modern ballasts within a few hundred milliseconds or less. In order to prevent such a high voltage, the ballast is shorted by the LED bulb or its associated thyristor clamp in an interruption of the load circuit.
- the thyristor clamp circuit which is also called a thyristor crowbar circuit, constantly monitors the rectified output voltage and ignites the thyristor of the clamping circuit when a defined, maximum threshold voltage is reached, thus short-circuiting the ballast device.
- this LED bulbs can be designed as an LED module, which instead of one or more Fluorescent lamps can be used in the lighting device with the corresponding base.
- an LED module includes, for example, the bridge rectifier and the thyristor clamp as a protection circuit.
- a corresponding lighting device which is left open during installation, whether later a fluorescent lamp or an LED light source is used.

- the LED lighting means is advantageously optionally configured with terminals which correspond in their arrangement to the LED light source and in their form which fluorescent lamps.
- the lighting device has, for example, a base body for holding the lighting means and a transparent or translucent cover, which can be placed on the base body and covers the lighting means.
- the cover can also shield the bulb from a potentially explosive atmosphere.
- the lighting device may include pedestals for receiving at least two different and parallel fluorescent lamps.
- this base is alternatively the corresponding LED illuminant or module used.
- the lighting device can be supplied with alternating voltage. However, a supply of DC voltage is possible.
