BINARY COMMUNICATION(binary signaling based on pulse) " and also it is transferred to the OSRAM of Massachusetts Denver
Copending U.S. Patent Application No._ of SYLVANIA company/_, _ described in those.Therefore, control input and cause voltage
Change circuit 202 and generate the service voltage of normal supply voltage and/or minimizing based on the input received.In some embodiments
In, master controller 200 alternatively or cumulatively includes the instruction of storage, its can during fabrication and/or before being sold and/or
In some are stored in master controller 200 At All Other Times, thus the instruction stored is at special time and/or based on via one
Or the specific operation condition of the multiple load being connected to primary module 104 from module is to provide to be sent to voltage changing circuit
One or more control inputs of 202.In other words, master controller 200 can receive control by any way and input, and then
Control input is provided to voltage changing circuit 202.
Although being only illustrated in fig. 2 from module 106A, but from module 106B, from module 106 ... from module 106n
Of course, and certain in certain embodiments, there are (multiple) from module 106A and similarly configure.Therefore, from module 106A
It is any from module that disclosed configuration can be applied to from module 106A-n.Include that voltage changes sensing electricity from module 106A
Road 204, from controller 206, filter circuit 208 and output circuit 210.Load 108A is coupled to from module 106A, and
More particularly, output circuit 210 it is coupled to.Voltage changes sensing circuit 204 and filter circuit 208 is configured to from main mould
Block 104 receives service voltage, and service voltage is the service voltage of normal supply voltage or minimizing.Voltage changes sensing circuit
204 are configured to be supplied voltage to generation logic-level voltages based on receive.Logic-level voltages corresponds to be received
Change on service voltage, and therefore correspond to be communicated to the information from module 106A by primary module 104.Such as, receive
Normal supply voltage can cause voltage to change sensing circuit 204 and generate logic level " 1 " (such as, 24V), and receive and subtract
Few service voltage can cause voltage change sensing circuit 204 generate logic level " 0 " (such as, 10V), or vice versa as the same.
The particular combination of " 1 " and " 0 " can correspond to, for the particular command loading 108A about it from module 106A, such as but not limit
It is formed on the operating parameter changing load 108A.Certainly, other change on the service voltage received also is possible, such as but
It is not restricted to latch and (such as, only after voltage change sensing circuit 204 one after the other receives two different service voltages, occurs
Change in logic level).Alternatively or cumulatively, other combination of " 1 " and " 0 " is used for the communication information.
Changed sensing circuit 204 by voltage to send (multiple) logic-level voltages to from controller 206.From controller
The logic-level voltages received is construed to come the communication of the information of autonomous module by 206.From controller 206 with any amount of
Known way performs this explanation.Such as, can include accumulator system from controller 206, this accumulator system is by " 1 " and " 0 "
Combination store in a lookup table, the most each combination is associated with the sequence of particular command and/or order.Alternatively or additional
Ground, specific voltage logic level sequence can utilize from controller 206 to cause one or more particular electrical circuit activation and/
Or deexcitation.From controller 206 by control based on the information communicated explained output output to output circuit 210.Should
The form controlling output depends on the information being communicated to from module 106A.Such as, in certain embodiments, controlling output is to draw
Play output circuit 210 and make the signal that the frequency of its load output signal changes, such as but be not restricted to pulse-width signal.One
In a little embodiments, this control output is the signal causing amplitude of variation that output circuit 210 makes its load output signal.From control
Device 206 can export any control output of the operation that can affect load 108A.
Filter circuit 208 also receives service voltage from primary module 104.Filter circuit 208 is configured to substantially
Continuous print normal supply voltage supplies to output circuit 208, and normal supply voltage is sent to load from output circuit 208
108A, as described below, receive, regardless of filter circuit 208, the service voltage that normal supply voltage still reduces.Change
Yan Zhi, filter circuit 208 protection load 108A, causing it never to receive will interrupt and/or the operation of amendment load 108A
The service voltage reduced, and still allow for receiving, from module 106A, the service voltage reduced, therefore it is allowed over service voltage. simultaneously
On change information is communicated to from module 106A from primary module 104.Filter circuit also filter in service voltage any not
The change wanted.
Output circuit 210 receives normal supply voltage as coming since the control of controller 206 is defeated from filter circuit 208
Go out (if any).Load output is provided to the load 108A being connected to from module 106A, this load by output circuit 210
Export normal supply voltage based on output and control output (if any).Therefore, without controlling output, then export
The normal supply voltage of output is transferred to load 108A by circuit 210 simply from filter circuit 208.But, primary module 104
The change of the operation of the load 108A being connected to from module 106A should be communicated to from module 106A, output circuit make for
Control since controller 206, corresponding to operational change exports, to be appropriately modified from filter circuit 208
The normal supply voltage that exported thus create the load output of the operational change wanted caused in load 108A.
Although be shown as the element separated in fig. 2 from controller 206 and output circuit 210, but implement at some
In example, these can be combined into the discrete component with the function from both controller 206 and output circuit 210.Therefore, example
As, the circuit of combination can be the microcontroller being able to carry out the operation from both controller 206 and output circuit 210, and
Therefore will be connected to filter circuit 208 and voltage will change both sensing circuits 204.
