Definitions
- the invention relates to a device for lighting the expansion racks in a strut according to the preamble of claim 1.
- the usual way and necessary V is provided in a strut, each extension frame with light sources through which the expansion gesture !! and the adjacent strut can be illuminated. Since it must be assumed that a strut has 100 or more expansion racks, it is obvious that the lighting of the extension equipment requires a considerable amount of space, which is all the more serious since the supply voltage for the lighting fixtures must be low for safety reasons to prevent sparks when switching to avoid.
- the object of the invention is to equip the device for illuminating the expansion racks with little effort so that the device is secure.
- the invention makes use of the knowledge that, on the one hand, the control power supply units must have a nominal current for safety reasons which is significantly higher than the expected current requirement of the connected expansion controls. This is related to the peculiarity of the expansion controls, that by entering commands on an expansion control, only one of the neighboring expansion controls can be operated, so that the power requirement of the expansion control used to enter the commands is at most low.
- the free capacity of the control power supply unit is used to illuminate the expansion control unit serving to enter the commands and possibly also the expansion control units being operated.
- all expansion controls connected to the same control power supply can be activated simultaneously by remote control or by automatic operation, that is to say without the presence of an operator at the expansion frames concerned, so that lighting of this expansion frame is not necessary.
- a special feature of the invention is that the lighting takes place only in the low-voltage range (not more than 60 V) and preferably in a voltage range that also serves as a control voltage, for example 12 V.
- LED i.e. h .:
- the developments of the invention according to claims 4 serve the purpose of always illuminating operated expansion controls, so that the process in the face is always visible to the operator.
- the developments of the invention according to claims 5-9 serve the purpose of avoiding overloading the control power supply due to the current requirement of the light sources even when control power supplies of relatively low nominal power with a relatively low nominal current are used.
- a current limiting device is provided in the common supply line between the control power supply on the one hand and the individual expansion control and the associated lighting on the other hand, by means of which the lighting is switched off or is throttled so far when a certain predetermined maximum current is exceeded, that the electricity required for the expansion control is always available and there is no fear of a failure of the control power supply.
- the effort for the high-voltage network is avoided on the one hand, since this is also the case for the lighting Control voltage serving high-voltage network is used; on the other hand, the control power supply can be designed with a weak nominal power and the continuous operation of the lighting in the whole longwall, ie at all expansion racks, can be made possible by a light power supply.
- This light power supply unit is preferably combined with the control power supply unit to form one structural unit.
- the good illumination of an extension part also depends on the number of light sources.
- the possibility is created to supply a larger number of light sources from a control power supply or light power supply without increasing its nominal power or without causing an increased power requirement, which may be necessary. leads to failure of the power supply or to switching off the lighting.
- expansion controls 1-7 of the corresponding expansion frame are shown. These expansion controls are in groups of three, for example: 1-3; 4-6 fed by a common control unit 8.
- the control unit 8 transforms the voltage from 220 V in the line 10 down to 12 V DC in the supply line 9.
- the control line 11 and the light line 12 branch off from the supply line 9, through the three light sources 13, 14 and 15 be fed.
- the expansion control devices 1-7 are connected to one another via a bus line 18. Activation of each of the expansion controls 1-7 can take place via the bus line 18, specifically by entering commands at a central control room or at one of the neighboring expansion controls.
- the current flowing in the supply line 9 is measured by a current measuring device 16.
- the current measuring device 9 switches the priority switch 20, which is arranged upstream of the light sources 13, 14, 15, via priority line 17.
- the priority switch 20 is switched on in normal operation and is switched off when a current is measured in the current measuring device 16 which exceeds the limit value defined as impermissible. As such a limit value of the current z. B. the sum of the nominal current of the three light sources 13, 14 and 15 can be defined.
- the limit value in the current measuring device 16 can, however, also be set higher, namely by the current requirement of two expansion controls higher than the sum of the nominal current of three light sources or the illuminations of three expansion racks.
- the expansion controls provide a lock in the sense that the expansion control cannot be actuated and therefore the assigned expansion frame cannot be moved or moved if there is a person in the area of the expansion frame, for example: an operator which gives control commands from the expansion control.
- the interlocking therefore means in particular that switching commands for the same fitting equipment cannot be triggered by a removal control.
- the circuit can also be designed so that not all but only some light sources are occupied by priority switches and can be switched off.
- the current measurement by current measuring device 16 can also be used to switch on a switch 20, which in this case takes the place of the priority switch 20.
- the light sources 13, 14, 15 of three adjacent expansion racks can be switched on when power is being consumed on one of the expansion controls that are assigned to these expansion racks, ie: here an operation, moving or other movement of a expansion rack takes place.
- FIG. 1 A prerequisite for this design is that the control power supply is designed so large that its rated current exceeds the sum of all consumers connected to the control power supply, ie: expansion controls and light sources, as is the case with the design according to FIG. 3.
- each expansion control 1 1, 2, 3...
- the presence detector 21 When the presence detector responds, the relevant removal control is deactivated via locking line 23, so that the removal frame assigned cannot be moved or otherwise moved by this removal control.
- the light source 13 or 14 or 15 is switched on.
- FIG. 2 it is shown that the light sources 13, 14, 15 can be switched on or off simultaneously by three adjacent expansion racks when one of the presence detectors 21 responds .
- the presence detectors 21 detect the presence of a person and, in the circuit according to FIG. 2, lead to the fact that when a person is present in the area of the presence detector, on the one hand the lighting of three neighboring construction elements is switched on, but on the other hand the activation of the construction frame in the area of which the person is located , is switched off.
- the design of the power supply units 11 ensures that the nominal current of each power supply unit is in any case higher than the sum of the maximum currents of all expansion controls and light sources which are supplied by the power supply unit.
- the light sources 13, 14, 15 of three adjacent expansion racks can be switched on manually or by remote control or automatically depending on certain commands if power is being consumed on one of the expansion controls that are assigned to these expansion components, ie: here an operation, relocation or other movement of an extension rock takes place.
- FIG. 4 shows schematically that the light sources 13, 14 and 15 each consist of several LEDs. It should be pointed out that this embodiment can replace the light sources 13, 14, 15 shown there in all circuits according to FIGS. 1-4.
- each light source 13, 14, 15 consists of two groups of three LEDs each. Both groups are fed by a common light guide 12, but with the interposition of an inverter 26, which generates an AC voltage.
- One group of LEDs is transparent when the voltage is positive and the other group when the voltage is negative.
- the converter frequency of z. B. 100 Hz there is no impairment of the lighting quality, but a better use of the electrical power available for lighting.
