Below, with reference to accompanying drawing and embodiment, the present invention is described further：
Reference picture 1 and Fig. 2, a kind of control circuit of high power wall washing lamp described in the present embodiment include controller 1, lighted
Lamp 2, wire 3 and controlling switch 4.The controller 1 and electroluminescent lamp 2 are connected with wire 3 respectively.The controlling switch 4 with it is described
Wire 3 connects.The quantity of the electroluminescent lamp 2 is more than or equal to two.Each electroluminescent lamp 2 is parallel on wire 3.Each electroluminescent lamp 2 divides
It is not connected with a controlling switch 4.The controlling switch 4 is relay either normally closed switch or normal open switch.The controller 1
Available for control electroluminescent lamp 2.The wire 3 can be used for the signal of transmission control unit (TCU) and electroluminescent lamp.The controlling switch 4 at least has
There are the first working condition and the second working condition.When 2 normal work of electroluminescent lamp, the controlling switch 4 is in the first work
State, such as off-state；When the electroluminescent lamp 2 is abnormal, the controlling switch 4 is in the second working condition, such as connected state
State.Under second working condition, signal then can not be by electroluminescent lamp 2, and now signal can be transmitted by controlling switch 4, so as to
Other electroluminescent lamp energy normal works of electroluminescent lamp 2 by abnormal luminous lamp 2 without being influenceed.
Preferably, the control circuit of the high power wall washing lamp can also include control unit 5.Described control unit
5 with controlling switch 4 and or electroluminescent lamp 2 can be connected by wire 2；Described control unit 5 be used for detect electroluminescent lamp 2 and or control
Switch 4.Described control unit 5 can be used for sending monitoring signal, such as when some electroluminescent lamp exception, the control unit 5 can be sent out
Abnormal signal is sent, and control signal is further ensured that other electroluminescent lamps 2 from abnormal luminous lamp normal through controlling switch
2 influence, moreover it is possible to improve the efficiency for searching abnormal luminous lamp 2.
The controller 1 is DMX512 lamp dimmers.DMX512 controllers are capable of the DMX512 control letters of outputting standard
Number, it can cascade multiple electroluminescent lamps 2.In order to increase the service life of the control circuit described in the present embodiment, the electroluminescent lamp 2
For LED.
The wire 3 include the first wire 31 (such as A lines), the second wire 32 (such as A lines) and privates 33 (such as
GND lines).Each electroluminescent lamp 2 at least includes the first pin 21, the pin 23 of second pin 22 and the 3rd respectively.First pin 21
It is connected to the first wire 31, second pin 22 is connected to the second wire 32, the 3rd pin 23 is connected to privates 33.Institute
It is signal transmssion line to state the first wire 31 and the second wire 32.Privates 33 is ground wire.First wire 31 and second
The quantity of wire 32 is respectively one or two.The wire 3 is using the wiring of RS485 wire laying modes.The electricity of the wire 3
Pressure -7V to+12V.
Because the wire 3 of the control circuit of the high power wall washing lamp in the present embodiment is connected up using RS485 wire laying modes, institute
RS485 drivers 34 can also be connected by stating on wire 3.The maximum of the control circuit signal transmission rate of the high power wall washing lamp is
10Mbps.The node of the wire 3 can be 32 to 128.Preferably, each node can be in parallel one
Electroluminescent lamp 2, and each electroluminescent lamp difference controlling switch 4 in parallel.When the length of wire 3 is more than predetermined value,
The both ends of the wire 3 are respectively arranged with resistance.The resistance of each resistance is equal to the characteristic impedance of wire.The predetermined value can be
300 meters or so.RS485 wire laying modes can use balance transmission and differential received, therefore so wiring has suppression common mode interference
Ability, its transmission signal can be restored beyond km, such as the signal of the control circuit of high power wall washing lamp maximum passes
Defeated distance about can be 1219 meters, error be ± 15 millimeters, due to the signal transmission it is distant, it is possible to so that the control
Circuit processed expand usable floor area or apart from when advantage of lower cost.In addition when RS485 wire laying modes are used for multi-point interconnection very
It is convenient, many signal wires can be saved.It can be networked using RS485 wirings in addition and form distributed system, it allows parallel connection three
12 drivers and 32 receivers.Driver and receiver herein is the driver and receiver of electroluminescent lamp.
The controlling switch 4 is relay or normally closed switch；Described control unit 5 is MCU (Micro Control
Unit, micro-control unit).MCU can enter row write code, and write address is carried out to the electroluminescent lamp 2 being attached thereto, therefore can not have to write
Location line.The other MCU has signal arrangement and cutoff function.After some 2 exception of electroluminescent lamp, the controlling switch 4 may be such that
Signal can continue to propagate to follow-up electroluminescent lamp 2, so that other normal electroluminescent lamps 2 are unaffected, conveniently check
Impaired electroluminescent lamp 2.The controller 1 is provided with the signal detection and feedback of detection electroluminescent lamp, is opened with control relay
Or close.
Below so that electroluminescent lamp is LED as an example, the control circuit of high power wall washing lamp of the present invention is illustrated；
Due to not connecting control unit 5 (MCU) and controlling switch 4 (relay) respectively in each LED, system is not being led to
Electricity, control unit 4 (MCU) damage, in the case of no signal LED input and output be still conducting state, ensure that entirely
The reliability in loop.AB signals input into control unit 5, control unit 5 and export AB letters again by shaping during system normal operation
Number, it can so avoid a LED abnormal situation of LED before and after influence that goes wrong from occurring, easy-to-look-up problem points.
Because each LED is connected by the way of in parallel, so Light Control Unit described in the present embodiment has amplifier in itself
Function, signal can be amplified, therefore additionally mounted amplifier can be omitted.
In addition the control circuit of high power wall washing lamp of the present invention can also be applied to and monitor, will the present invention it is real
Apply the electroluminescent lamp described in example be substituted for camera i.e. can be used.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
Corresponding change and deformation, and all these changes and deformation should all belong to the protection domain of the claims in the present invention
Within.
