Definitions
- the invention relates to a lighting device with a plurality of LEDs arranged on a flexible carrier according to claim 1.
- Preferred embodiments of the invention are defined in the dependent claims.
- a lighting device of the aforementioned type is known from DE 20 2013 131 820 U1 and EP 3 179 155 B1 . Furthermore, a lighting device with a large number of LEDs is available GB 2 536 300 A and US 2012 / 080944 known.
- LED light strips that can be connected directly to a mains voltage are also known from the CN 204376382 U , CN 204664982 U , CN 104507227 A , CN 205726534 U and CN 204629195 U .
- a generic lighting device is the lighting of an elevator shaft.
- an upper end of a clear tube in which there is an LED strip that has the flexible carrier described above, is attached to a ceiling of an elevator shaft.
- a lower end is clamped to the sole of the elevator end.
- the supply lines are connected to the mains voltage via a plug.
- the generic lighting device does not emit any light, so that a supplementary emergency lighting device must be provided.
- the invention is based on the object of further developing the lighting device described above in a way that is advantageous for use.
- the lighting device can therefore not only be used as proper elevator shaft lighting, but also as emergency lighting.
- the second voltage can be a direct voltage or an alternating voltage.
- the second voltage is preferably provided by an accumulator and an inverter connected to it.
- the accumulator supplies a direct voltage of 12, 24, 48 volts or another suitable voltage, which is stepped up to a second alternating voltage by the inverter.
- this alternating voltage is lower than the first alternating voltage, but sufficiently high that the light-emitting diodes arranged on the flexible carrier still emit sufficient light intensity.
- the ratio of the second alternating voltage to the first alternating voltage is less than 0.9 or preferably less than 0.8.
- the flexible carrier according to the invention can be arranged in a flexible, transparent tube and has a large number of groups of LEDs which can be connected in series. Each group of LEDs may include an electrical circuit disposed on the flexible support that drives the group of LEDs. The electrical circuit converts the alternating voltage distributed over the flexible carrier via a pair of supply lines into a direct voltage which is applied to the series-connected light-emitting diodes.
- the electrical circuit is designed such that a second alternating voltage that is reduced compared to the first alternating voltage reduces the current flowing through the group of light-emitting diodes in such a way that the light output emitted by the light-emitting diodes is correspondingly reduced.
- the light output provided by such an LED strip arranged in an elevator shaft is sufficient, for example, to produce an illuminance of at least 5 or at least 15 lx on the ceiling of an elevator car.
- the electrical circuit is in particular designed in such a way that the light-emitting diodes emit a light output of at least 800 lm/m when the first alternating voltage is applied and a maximum light intensity of 100 lm/m or a maximum of 25 lm/m when the second alternating voltage is applied. It can also be provided that the electrical circuit is designed in such a way that a power of at least 0.8 W/m is emitted when the first alternating voltage is applied, which can preferably be 220 V, but also 110 V, and when the second is applied AC voltage delivers a maximum power of 0.2 W/m.
- the LED strip formed by the flexible carrier according to the invention has a large number of light-emitting diodes arranged in the extension direction of the strip, the light-emitting diodes being at a distance of 10 to 60 mm.
- the light-emitting diodes can be combined into groups, with several groups being arranged one behind the other in the direction of extension of the flexible carrier.
- Each group of light-emitting diodes preferably has an associated electrical circuit that has a rectifier.
- Two supply lines extend over the entire length of the flexible support and are used to supply the electrical circuits with the mains voltage.
- the supply lines emerge from a covering of the flexible carrier, preferably made of plastic, and form connection contacts with which the LED strip can be connected to a ballast element via supply lines.
- the ballast element can have a changeover switch, for example a relay, with which the first alternating voltage or the second alternating voltage can be fed into the supply lines.
- the relay can have a magnet that is powered by the mains voltage. If the magnet is energized, a contact of the switch, which is connected to the mains voltage, is connected to the supply line.
- the changeover switch can either go into a neutral state, in which there is no voltage at the connection contacts, or the changeover switch can go into an emergency lighting operating state, in which the changeover switch connects the connection contact to a second alternating voltage.
- the ballast can have a battery or be connected to a battery that supplies a direct voltage that is converted to the second alternating voltage using an inverter.
- the Figure 1 shows an LED strip 1, which corresponds to one DE 10 2018 121 325 can be trained.
- the LED strip can also be designed as shown in the EP 3 179 155 B1 or is described in one of the documents mentioned at the beginning.
- the LED strip 1 has several groups of light-emitting diodes 16 arranged in the direction of extension of the LED strip 1. Each group of light-emitting diodes 16 is operated by an electrical circuit 4.
- the electrical circuit 4 has a rectifier with which a mains voltage is rectified.
- the electrical circuit 4 forms a direct current source, with the current provided by the electrical circuit 4 flowing through several light-emitting diodes 16 connected in series.
- the level of the current that is fed into the light-emitting diodes 16 through a feed line 17 and that emerges from the line 17 ' depends on the level of the alternating voltage applied to the electrical circuit 4.
- a supply line 6 is connected to the connection contacts 5, 5 'there.
- the transparent plastic shell not shown in the exemplary embodiments, in which the LED strip 1 extends, has an upper end with which it can be attached, for example, to the ceiling of an elevator shaft.
- a ballast element 7 is provided, which has an output from which supply lines 6, 6 'emanate, which are connected to the connection contacts 5, 5' are connected.
- the ballast element 7 has two inputs. At the first input there is a power cable 18, which can be connected to a power connection contact 13, 13 '.
- An accumulator 15 is connected to a second input of the ballast element 7 and supplies a direct voltage U3, for example of 12, 24, 48 volts.
- This direct voltage U3 is converted by an inverter 14 into a second alternating voltage U2, which is lower than a first alternating voltage U1, which corresponds to the mains voltage at the mains connection contacts 13, 13 '.
- the alternating voltage U1 is 230 V.
- the second alternating voltage U2 is preferably 165+/-10 V. However, the second voltage can also be a direct voltage. Your value is then around 217 V +/- 10 V, but can also be lower.
- a changeover switch 8 is provided in the ballast element 7, which can be designed as a relay.
- a contact 12 is connected to the connection contact 5.
- the contact 12 can optionally be connected to three further contacts 9, 10, 11. If the contact 12 is connected to the contact 9, the second alternating voltage U2 is present at the connection contact 5. If the contact 12 is connected to the contact 10, the first alternating voltage U1 is present at the connection contact 5. If the contact 12 is connected to the contact 11, there is no voltage at the connection contact 5, so that the light-emitting diodes 16 of the LED strip 1 do not emit any light.
- the mains voltage for example 110 V or 230 V
- the power connection contact 13' is connected directly to the connection contact 5' via the power cable 18.
- the power connection contact 13 is connected to the power cable 18 to the contact 10 of the switch 8.
- a magnet (not shown) or a suitable electronic circuit component creates a conductive connection between the contacts 10 and 12, so that the mains connection contact 13 is connected to the connection contact 5.
- the mains voltage is then applied to the supply lines 3 ', 3, so that the light-emitting diodes 16 emit at least 800 lm/m light output.
- the lighting device can be switched off by actuating, for example, a switch, not shown, which connects the contact 12 to the contact 11 so that there is no voltage at the connection contact 5.
- the contact 12 If the mains voltage fails in normal operation, in which the contact 12 is only connected to the contact 10 when the mains voltage is present, the contact 12 automatically connects to the contact 9, so that the second alternating voltage U2 provided by the inverter 14 Connection contact 5 is present and the lighting device is operated with its emergency lighting function, in which the light-emitting diodes 16 emit a significantly lower light output.
- a lighting device which is characterized by a device for providing a second voltage, in particular alternating voltage U2, which is smaller than the first alternating voltage U1, and a changeover switch 8 with which the first U1 or second U2 alternating voltage can be fed into the conductor track arrangement 3 , 3'; 17, 17 'can be fed.
- a lighting device which is characterized in that the ratio U2 to U1 is less than 0.9 or less than 0.8.
- a lighting device which is characterized in that the second alternating voltage U2 is provided by an accumulator 15, which supplies a direct voltage U3, and an inverter 14, which converts the direct voltage U3 into the second alternating voltage U2.
