Background technology
In modern lighting system, usually send digital control instruction by central control unit to operating means.By these external control instructions, especially can stipulate brightness value, in order to obtain different illuminating positions.These operating means can be equipped with the address, control by the independent or grouping of central control unit in order to realize.
The control method of another extensive use is to control illuminator according to DALI (the luminous interface of digital address) standard.This standard is defined for numerically controlled interface and the transformat of operating means, wherein for a plurality of independently operating means, and can specified address.These operating means can be by the external control instruction by break-make or carry out brilliance control, and can start a specific condition of work such as Emergency Light state and inquiry error reporting.
The DALI standard is 16 Manchester codes, and it has realized the maximum dimmer speed when changing less than from 1% to 100% the brightness of 0.7 second.High level is positioned at almost 16V scope, and low level is in the voltage that is almost 0 volt.
Thereby the modern operating means that comprises interface agency can stop luminescent device really when receiving open command work reduces himself loss such in waiting operation, but, the control circuit of this operating means is workable still, can't accomplish to make power component and electrical network to disconnect, as a result, this operating means also receives reactive power and in most of the cases also receives low active power in waiting operation.In the operating means that for example is widely applied at the luminescent device of modern office buildings, this reactive power is undesirable for the mains supply device, and should keep low-level as far as possible exactly.Wait active power and also increase to considerable for main facilities, this should reduce as far as possible.So-calledly wait operation generally also referred to as inactive state.What be called as operating state is such state, that is, and and at least one operating means operating light-emitting device.
Application DE10329876A1 has described a kind of for gaseous discharge lamp and operating means that comprise interface agency, wherein the power component of this operating means can be disconnected under open command fully, and the logical circuit in interface agency is monitored this bus, if activity is arranged on bus, the power component of start-up operation device again., the interface agency of operating means has complicated and structure with high costs, and the power component of operating means also must adjust accordingly.

Embodiment
Embodiment below with reference to the illuminator with control device of the present invention illustrates operating means and other control device that the present invention is connected with electrical network by control device.
The present invention can be used in all types of luminescent device operating means.At this moment, can use distinct luminescent device, especially can use the light-emitting diode of gaseous discharge lamp, Halogen lamp LED or organic or inorganic.
Operating means 1 and control device 10 are parts of illuminator A.
In addition, other control device 11 can be connected on bus 21.
Various control device 11 be also referred to as actuator and can be various transducers such as motion sensor or luminance sensor, also can be the touch-screen that the actuator that can be controlled by the user such as switch, button or band be useful on the user interface that illumination controls.
Bus 21 consists of with two-wire data wire form, and its transmission is as the digital signal with low dc voltage of control command.By bus 21, for example complete the transfer of data according to the DALI standard.Interface circuit 4 and control device 10 can receive the control command according to the DALI standard.
The transfer of data that is noted that control command not necessarily realizes in the wired connection mode by bus 21, but for example can realize with wireless mode by wireless link, perhaps or by power line carrier, PLC (PLC) transmits by power supply network 20.For above-mentioned transmission variant, exist respectively to be similar to the line transfer of data with the standardization transmission method of DALI standard, wherein according to the inventive method, the transfer of data that can change by identical bus 21.
Control device 10 can be controlled operating means 1 independent or a plurality of luminescent devices by bus 21, and wherein, it receives digital control instruction and can also send digital control instruction.When having the corresponding open command that is received and estimated by control device 10 on bus 21, control device 10 can disconnect the operating means 1 that is connected with electrical network, so that its power quantities received reduces to zero.Thus one, operating means 1 is converted to inactive state from operating state.Therefore, can significantly reduce the loss that waits of illuminator.Whether control device 10 is gone back monitoring bus 21 has control command and can store this control command.
Because by disconnecting with the mains supply device, operating means 1 is not worked fully, so can also not make internal control circuit work.But at off period, operating means 1 is not worked because of its control circuit can't be received in the control command that sends on bus.Because these control commands may comprise various information or inquiry, so these control commands may be relevant to the operating means 1 that is disconnected.
If the mains supply device is switched on again, operating means 1 must first start again, especially must first start its control circuit.But, operating means 1 being sent when going code again, operating means 1 can't receive this control command because of its disconnection.Control device 10 with whether control command is arranged on monitoring bus 21, even if in the disconnected phase, is also like this.In this disconnected phase, control device 10 can receive, estimates and be stored in all control commands that send on bus 21.Control device 10 receives and stores this and goes code, and again connects the mains supply device for corresponding operating means 1, and therefore this operating means 1 is converted to operating state from inactive state.Because connected the mains supply device, so operating means 1 begins to start and its control circuit of initialization.After being connected of complete operation device 1 and mains supply device, the control command that control device 10 will be received and store sends to operating means 1.In case this control circuit is task again, operating means 1 can receive control command again.
Because general operation device 1 brightness value with maximum possible when the mains supply device is connected is controlled luminescent device, so this may cause not causing that the luminescent device that the observer notes starts.Commercially available different operating device 1 has distinct control circuit in market, therefore also can have different startabilities.
If the observer for example expects very low brightness and correspondingly sent such control command by control device 11 to illuminator A when illuminator A originally disconnects, under rough sledding, at first operating means 1 starts with highest brightness value, only after control device 10 sends control command, just be transformed into low brightness value.For can control all presumable operating means 1, for the reliable startup of operating means 1, must be as certain time of standby consideration, just and control command only can be sent to operating means 1 through after certain time.
In order to make operating means 1 respond as far as possible fast the control command that sends, control device 10 can repeatedly send control command in succession.Therefore the irrespectively retentive control instruction of startability of energy ensuring and controlling circuit conveys to operating means 1 as far as possible fast.
Go code again and may be caused by different control commands.Can be from the illuminator A that disconnects (because desired brightness value is 0) require one greater than 0 brightness value.But, also can indicate special lighting condition such as Emergency Light work (other example?).
Open command can be for example for the control command that obtains brightness value 0, but can be also for selectively making the idle control command of a plurality of independent operation devices 1.
Disconnected phase can be activated by the transmission of open command and mean that each independent operation device 1 will be disconnected at least to off-state in other words.
Operating means 1 is completed by electrical network circuit breaker 5 with electrical network coupling and the electrical network disconnection of mains supply device.This electrical network circuit breaker 5 can be switch, as semiconductor switch or relay.Electrical network circuit breaker 5 can be integrated in control device 10, but also can export to control by the control of control device 10.
Control device 10 can be controlled a plurality of independently electrical network couplers, therefore controls separate operating means 1, and its way is that it can be controlled a plurality of electrical network couplers and integrate in other words a plurality of electrical network couplers.Separate operating means 1 can be separated from each other by different addresses.
Go code in order to send, control device 10 can be stored the control command of receiving again again.It can or the control command that receives at last of storage or temporary transient storage, or can store the whole sequence of the control command of receiving by bus 21.Therefore, after the connection of complete operation device 1, the control command of sending on bus 21 in the disconnected phase still can be sent to operating means 1 afterwards.In this way, these operating means 1 also can constantly also be configured and obtain the information sent by control command subsequently at one.Therefore, the change of illuminator configuration can also be carried out in the off-state of operating means 1.When for example not needing to start illumination and therefore disconnect this operating means by operating means 1 in office building in sun-drenched situation, that's how things stand, but the user will adjust the configuration of illuminator.Therefore, can disconnect luminescent device and carry out within such disconnected phase and adjust, be i.e. the change of configuration.
The user can be chosen in the electrical network coupler and connect the rear repetition rate that repeats to send control command by control device 10.This configuration for example can be identified for some light scene or the performance graph of illuminator and operating means 1.
In addition, control device 10 can automatically perform the adjustment of the order of the control command that sends for the control command of transmission, perhaps also can add other control command or delete some control command.In this way, when being transformed into high brightness from off-state, for example can obtaining one and allow the luminescent device that the observer feels comfortably cool start.Control device will not send desired high luminance values in the case at once, but first sends lower brightness value and send desired high luminance values after the process certain time-delay.Perhaps, can also first a general open command be sent to relevant operating means 1 after connecting the electrical network coupler, be only subsequently desired brightness value.
The power supply of control device 10 and control device 11 can be completed by bus-powered mechanism 12.At this moment, bus-powered mechanism 12 so gives bus 21 power supplies,, adopts the transmission according to the effective principle of so-called low state that is.In such transmission, as long as no the transmission of data, with regard to one of the long-term existence level of 12V for example.When transfer of data, level will arrive the level less than for example 2V, in order to transmit one.
In this way, there is permanent voltage on bus 21, therefore can gives control device 10,11 power supplies by bus 21.
Give control device 10,11 power supplies by bus-powered mechanism 12, can realize effective control device power supply, because only need to go up in one central location, line voltage is reduced to control device 10,11 the needed low volt voltage of power supply.
Also can keep carrying out for control device 10,11 power supplies in the disconnected phase of operating means 1 by bus-powered mechanism 12, because obtain effectively supply on energy by central bus administration of power supply 12, and this illuminator whole power quantities received in the case can significantly be reduced.
Perhaps, control device 10 can have the administration of power supply that is directly connected to the mains supply device of oneself.
Control device 10 can be by the state of bus 21 demand operating devices 1.And, control device 10 also can by direct-connected button or switch, by being used for programmable device interface, by touch-screen or other adjustment possibility or directly configure and control by the user.By direct control possibility, the user can also stipulate for example brightness value of control command.
For control device 10 can simply be installed, control device 10 can be arranged in DIN bus-bar casing.
