Definitions
- the invention relates to a lighting unit consisting of a lamp, a power supply source and a socket provided for a usable lamp, in which two electrical contacts are arranged.
- the lighting unit also has a safety device against electric shock.
- the invention also relates to a method for protecting against electric shocks when the lamps are switched on. These light units are used in particular where such systems are protected against unauthorized access, e.g. to be secured by children.
- Lamps with illuminants that are operated with mains voltage are widely used in the area of children's rooms. If the lamps are accessible to children, such as night table lamps or wall-mounted reading lamps, there is a risk that children unscrew the lamps, for example when the lamp is switched off, and reach into the socket after switching on the lamp. If the electrodes are touched, an electric shock can occur with the corresponding consequences.
- EP 96 2014 38 describes a closure device for socket openings of an electrical socket.
- the socket openings can be closed with the aid of locking elements which can be adjusted in a defined angular position.
- a lighting unit which, according to the genus, consists of a lamp with a power supply source and a socket provided for a replaceable lamp there are at least two electrical contacts.
- this lighting unit additionally has a safety device against electric shock.
- this securing device consists of at least one control element with which it can be checked whether the illuminant is inserted and / or free of defects.
- the safety device has at least one control element controlled by the control element. This control element serves to interrupt the electrical supply of at least the live electrical contact, also called the phase.
- the securing device prefferably has at least one unlockable closure element which, when the illuminant is not inserted, prevents contact with at least the live electrical contact.
- the safety function is achieved in that the power supply of at least the live electrical contact, also referred to as the phase, is interrupted by electrical or electronic components. This makes it possible that the contact of the electronic contacts remains harmless when the illuminant is not used. The same applies in the event that the lamp is inserted but defective and must be replaced. Replacing the illuminant entails an increased risk of electric shock when the illuminant is replaced, since it cannot be checked whether the lighting unit is still supplied with power.
- the second variant provides that with the help of a
- Closure element touching at least the chip electrical contact is prevented.
- This mechanical variant can also be combined with the electronic variant described above.
- the securing device has a microswitch which performs the function of both the control element and that of the control element in one. This microswitch then interrupts the electrical supply to the live electrical contact when the illuminant is not used.
- the at least one microswitch is preferably built into the socket in such a way that the circuit is closed when the lamp is inserted into the socket. In order to increase the protection against accidental contact, several microswitches installed in different positions in the socket can be connected in series. The microswitch can directly interrupt the electrical supply of at least the live electrical contact.
- the microswitch can preferably also only take on the function of the control element.
- the microswitch is triggered, which then controls a relay that acts as a control element.
- the electrical supply to at least the live electrical contact is then interrupted via the relay.
- control element provides a resistance sensor for testing of the resistance occurring between the electrical contacts.
- the resistance sensor registers when the resistance between the two electrical contacts is higher than would be the case with inserted 5th and non-defective illuminants.
- the resistance sensor then controls the control element, which interrupts the power supply of at least the live electrical contact. It must be ensured here that a change in resistance caused by a human being touching 0 does not lead to the deactivation of the controlled control element.
- this variant can also be used to prevent an electric shock when the lamps are destroyed. 5
- control element can consist of a resistance sensor in combination with a current flow sensor.
- the current flow sensor is used to check whether there is a current flow in the lighting unit in the case of a resistor that corresponds to an inserted lamp that is not defective, that is, a positive test result. This variant represents an additional safety check when using a resistance sensor. 5
- control element is designed as a radiation or light intensity sensor, for example an LDR, with which the radiation power emitted by the illuminant is checked.
- the variant can be carried out in such a way that after closing the circuit, for example by actuating a light switch, after a very short transition time, for example in the microsecond range, from an irradiation or light intensity sensor fitted inside or outside the socket, the light from the illuminant outgoing irradiance is checked. If this is radiant intensity below the value customary for an inserted and non-defective illuminant, the control element is activated by the control element to interrupt the electrical supply at least of the live electrical contact.
- control element as a temperature sensor, e.g. an NTC resistor is configured. These can be used to test the lamp temperature or the heat radiation emitted by the lamp. In this variant, too, a comparison is made with the heat development customary for an inserted and non-defective illuminant. If this value is undershot, the control element is activated by the control element to interrupt the electrical supply.
- a temperature sensor e.g. an NTC resistor
- control element is designed as a temperature sensor, it is possible in an advantageous further development that the temperature sensor also registers an increased heat development, such as can occur when the illuminant and / or the lighting unit overheats.
- the same additional safety function can be achieved by introducing a special temperature sensor with a corresponding control element or by connecting to an existing control element in the lighting unit, regardless of the protective mechanism chosen.
- Such overheating can occur, for example, if the air circulation in the lighting unit and / or in the immediate vicinity of the illuminant is impeded, for example by covering the lighting unit with textiles.
- this variant is implemented such that the temperature in the Luminous unit is compared with a variable or fixed adjustable maximum temperature and when this maximum temperature is exceeded, the power supply of at least the live electrical contact is interrupted.
- control element is arranged in such a way that the measurement is carried out on the illuminant or in its immediate vicinity.
- In the immediate vicinity means that the distances from the illuminant known for such sensors from the prior art are maintained.
- a radiation or light intensity sensor or a temperature sensor is used, a further sensor which works according to the same principle and which is arranged away from the illuminant can be used in each case.
- the light intensity or the temperature of the surroundings can then be recorded with this sensor and a difference measurement with regard to the irradiance and / or the temperature can thus take place.
- the control element is preferably arranged in the socket, so that a compact securing device can be implemented.
- the control element is preferably between the power supply source and at least the live one electrical contact arranged. It is particularly preferred that the control element is also arranged in the socket.
- the securing device against electric shocks can also be designed in such a way that a voltage between the connection contacts of the illuminant to earth is prevented without a control element in the illuminant circuit.
- This can preferably be done by a so-called protective separation according to VDE.
- This relates to the protection against electrical currents through the body from the socket to the earth, but not against electrical currents through the body, in particular fingers, between the two contacts in the socket.
- This variant can be technically realized by ensuring through electrical or electronic components that the electrical supply is interrupted without or with tools accessible contacts or other components, if an electrical supply between one of the two electrical contacts in the socket and earth, but does not exist between the two electrical contacts in the socket.
- the socket can have a locking device which prevents the lamp from being unscrewed from the socket.
- This locking device is triggered when the lamp is inserted.
- the locking device can then be unlocked with the aid of a mechanical or electrical triggering device, which is preferably arranged in such a way that it is not possible for children to operate it and remove the lamp. It is important that the triggering device only requires increased effort and / or skill is to use.
- a modified illuminant can also be used, which has, for example, small barbs which engage in corresponding counterparts in the socket. This variant should also be referred to here as removal safeguard for the lamp.
- the socket is preferably designed as a threaded socket, the illuminant having a counter thread that can be screwed to this thread.
- Thread types E5, E10, E14, E27 and E40 are to be mentioned as preferred thread forms.
- the securing device according to the invention has a closure element, this is preferred as
- Aperture trained This is to be understood as an aperture known, for example, for cameras, which causes the aperture to close when the lamp is removed, for example by means of elastic bands or spiral springs.
- a release device When the cover is closed, it is then no longer possible to touch at least the live electrical contact. If the lamp is to be used again, a release device must be operated with which the cover can be opened against its self-closing mechanism. Alternatively, it is also possible that a trigger device is attached ", which ensures the automatic opening of the aperture during screwing in a light bulb.
- a method for protecting against electric shocks when the lamps are switched on is also included a power supply source and a socket for an insertable illuminant in which two electrical contacts are arranged.
- at least one control element arranged in the lamp is used to check whether the illuminant is inserted and / or is defect-free. If there is a negative test result, at least one control element, which is also arranged in the lamp, is controlled by the control element such that the electrical supply to at least the live electrical contact is interrupted. It is also possible to prevent at least the live electrical contact from being touched by a closure element when the illuminant is not used.
- the object according to the invention described here is mainly used in areas where the unauthorized contact of the electrical contacts in lamps must be avoided.
- This safety device is also used for the safe replacement of lamps, since it cannot be assessed whether the lighting unit is supplied with power.
- Fig. 1 shows a socket 1 with two electrical contacts 2 and 3, a power supply 4 and a thread 5 for receiving the lamp.
- the socket has an opening 6 for put the lamp on.
- the securing device in this variant is designed in such a way that a closure element 7 is arranged between the thread 5 and the opening 6, which closes the lower region of the socket when the lamp is unscrewed, so that contact between the two electrical contacts is avoided.
- This closure element 7 can then be opened again automatically or by a triggering device, not shown, when a new illuminant is inserted.
- FIG. 2 shows a version essentially analogous to FIG. 1.
- the closure element 7 is not arranged between the opening 6 and the thread 5, but rather between the laterally attached electrical contact 2 and the electrical contact 3 arranged at the base of the socket.
- the electrical contact 3 arranged at the base is the live electrical contact Contact, also called phase.
- the closure element 7 is opened in the same way as described in FIG. 1.
- FIG 3 shows a version with a removal lock as a variant of the locking device.
- This has a locking device 10, 11 between the thread 5 and the opening 6, which prevents the lamp from being unscrewed.
- the locking device is shown once in the open position 10 and in the closed position 11.
- the illuminant has a glass region 13 and a metallic region 14 with the thread.
- a plurality of securing bolts 15 are arranged on the metallic region 14. These can be inserted in the socket into the space 12 formed between the socket housing 1 and the closure element 11. be snapped. In this position, the lamp cannot be removed from the socket.
- the closure element By means of a release device which is designed in such a way that it cannot be operated by children, the closure element can be moved from the closed position 11 into the open position 10, so that the lamp can then be removed again.
- the socket has a securing spring 17 which, although it allows the lamp to be screwed in in the direction of rotation 16, prevents the lamp from being unscrewed since the securing bolts 15 snap into place on the securing spring 17.
- the securing spring 17 can be brought into a position with the aid of a triggering device, which is not shown here, so that the lamp can be unscrewed.
- Fig. 5 shows an exemplary embodiment of the electrical or electronic variant in which the circuit is interrupted with the aid of microswitches which act directly (without a relay) as a control element when no lamp thread is screwed in.
- Power supply source is indicated by the interchangeable poles L and N in their connections.
- the microswitches 32, 33 which are attached at locations that are difficult to access, are in the opened state when the socket is turned out.
- both microswitches 32 and 33 can be replaced by two microswitches connected in series, the switches connected in series being arranged at different points in such a way that they are difficult to switch on simultaneously by hand. can be switched.
- FIG. 6 shows an exemplary embodiment of the electrical or electronic variant, in which a check is carried out to isolate the voltage, to determine whether there is a resistance between two contacts which corresponds to that of a screwed-in lamp thread.
- a further side contact 18 is implemented in addition to the one side contact 2 provided for the voltage supply of the illuminant. Both side contacts work together as a control element.
- the further side contact 18 is connected to the coil of the relay 19.
- the circuit that triggers the relay is closed when the lamp is screwed in via the electrically conductive lamp thread.
- a contactor can only be guaranteed with this if it is ensured that the neutral conductor N of the supply line is connected to the side contact 2 and the phase L of the supply line to the foot contact 3.
- a resistance sensor registers whether the resistance between two electrical poles corresponds to that of a non-defective lamp.
- a resistance sensor 30 is first used to determine whether the resistance between the two electrical poles for connecting the illuminant corresponds to that of a non-defective illuminant. If the resistance is higher than that of a non-defective illuminant, the control element stops the power supply after a very short period of time (in the ⁇ s range).
- the resistance corresponds to that of a non-defective one Illuminant
- a current flow sensor 31 determines whether the current flow between two electrical poles corresponds to that of a non-defective illuminant. If the current flow is lower than that of a non-defective lamp, the control element stops the voltage supply after a very short period of time (in the ⁇ s range). If the current flow corresponds to that of a non-defective lamp, the control element releases the voltage supply. At the same time, the resistance measurement 30 is switched off in order to avoid potential problems.
- the current flow sensor 31 continuously maintains its control function until the lamp is switched off manually via the switching element 29. After switching off the current flow by switching off the lamp via the
- Resistance sensor 30 and current flow sensor 31 are implemented with the aid of electronic circuits.
- a radiation or light intensity sensor or a temperature sensor registers the light intensity or heat radiation or its temperature emanating from the illuminant, for example on its metallic mount.
- a radiation or light intensity sensor or a temperature sensor registers the light intensity or heat radiation or its temperature emanating from the illuminant, for example on its metallic mount.
- the control element 22 can be designed, for example, as an LDR (light-dependent resistor), as an NTC resistor (temperature-dependent resistor) or as a complex component which takes on a resistance corresponding to the heat radiation.
- FIG. 9 shows a further exemplary embodiment of this variant, which contains the electronic components trim resistor (adjustable resistor) 24, resistors 25, freewheeling diode 26, operational amplifier 27 and transistor 28.
- trim resistor adjustable resistor
- resistors resistors 25, freewheeling diode 26, operational amplifier 27 and transistor 28.
- the response threshold of the circuit can be changed without changing the control element 22.
- FIG. 10 shows an exemplary embodiment of the electrical or electronic variant, in which the contactor is achieved by a protective separation in accordance with VDE 0100 part 410.
- the circuit of the illuminant 21 is set up independently of the network (primary circuit) by means of an isolating transformer 23. Touching any of the contacts of the lamp circuit (secondary circuit) does not lead to a current flow through the body even if it comes into contact with the earth (PE) of the primary circuit at the same time. A current flow through the body while simultaneously touching both contacts of the secondary circuit cannot be prevented.
