Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment the invention will be further described：
Fig. 1 is the external structure schematic diagram of programmable electronic ballast of the present invention；
Fig. 2 is the dial-up control circuit schematic diagram of programmable electronic ballast of the present invention；
Fig. 3 is the circuit theory diagrams of programmable electronic ballast main control chip of the present invention.
Embodiment
To make the object, technical solutions and advantages of the present invention of greater clarity, with reference to embodiment and join
According to accompanying drawing, the present invention is described in more detail.It should be understood that these descriptions are merely illustrative, and it is not intended to limit this hair
Bright scope.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring this
The concept of invention.
As shown in figure 1, the programmable electronic ballast of the present embodiment, including electric ballast, outside electronic ballast body
Portion is provided with 5 toggle switch, and the toggle switch can set the power, electric current, fluorescent tube of the output of ballast to preheat
Electric current and fluorescent tube preheating time.Toggle switch possesses programing function, by changing the address bit of toggle switch, for changing ballast
The pre- thermocurrent of power, electric current, fluorescent tube of the output of device and fluorescent tube preheating time, realizing same ballast can be with different size
Fluorescent tube purpose.
Fig. 2 is the dial-up control output signal setting principle figure example of the present embodiment.
As shown in the figure：
5th dial-up -- preheating time position is set.When not dialling up, network node C_PRET open circuits, then Q802 conductings,
Q801 ends, and network node TPRE is high impedance output；When dialling up, network node C_PRET ground connection is 0V, then Q802 is cut
Only, Q801 is turned on, and it is 0V outputs that network node TPRE is with being pulled down to.
3rd, 4 dial-up -- pre- thermocurrent position is set.When not dialling up, network node C_PREI1/2 open circuits, then
Q804/Q808 is turned on, and Q803/Q807 cut-offs, network node PREI1/2 is high impedance output；When dialling up, network node C_
PREI1/2 ground connection is 0V, then Q804/Q808 ends, and Q803/Q807 conductings, it is 0V defeated with being pulled down to that network node PREI1/2, which is,
Go out.
1st, 2 dial-up -- output current and power position are set.When not dialling up, network node C_WORKI1/2 is opened
Road, then Q805/Q806 conductings, network node WORKI1/2 are that 0V is exported；When dialling up, network node C_WORKI1/2 connects
Ground is 0V, then Q805/Q806 ends, and network node WORKI1/2 is high impedance output.
Fig. 3 is the schematic diagram of main control chip work：
As shown above, the network node output signal set in Fig. 2 is connected to the corresponding node on the upper figure left side.
Such as TPRE signals, when the electric capacity for the CT pin for for C201 is then pulled to 0V during 0V, increasing master chip so as to increasing preheating
Time；When for high impedance when, then it is ineffective equivalent to open circuit, C201.
Such as PREI1/2 signals, when for R208/R209 is then pulled to 0V during 0V, the resistance for reducing the PCS pin of master chip is big
It is small, voltage signal is reduced so as to increase pre- thermocurrent；When for high impedance when, then it is ineffective equivalent to open circuit, R208/R209.
Such as WORKI1, WORKI2 signals, when for R205, R218 are then pulled to 0V during 0V, reducing the electricity of the CSP pin of master chip
Resistance, voltage signal is reduced so as to reduce output current and power；When for high impedance when, then lost equivalent to open circuit, R205, R218
Effect.
U201 is UBA2014 electronic ballast control integrated chips in figure, is controlled by setting a series of its pins
The preheating of uviol lamp, start, operating current.Traditional ballast design custom is the only function by uniquely setting up each pin
To match single-minded fluorescent tube, such as preheating time 12S, pre- thermocurrent 2.0A, lamp current 2.0A, power 320W.And the design
By adding a multidigit toggle switch SW1 during unique distinction（Such as 5）, change master chip by setting the on-off of dial-up
The state of a control of each pin, such as preheating time may be configured as 12S, 20S（1 dial-up control）, pre- thermocurrent could be arranged to
1.5A, 2.0A, 2.5A etc.（2 dial-up controls）, lamp current may be configured as 2.0A, 2.2A, 2.9A etc.（2 dial-up controls）, work(
Rate may be configured as 240W, 320W etc.（2 dial-up controls）.Such a specification ballast can both be set specifically for single fluorescent tube
Optimal parameter, also can be with a variety of different size fluorescent tubes.
Additionally by ballasts of the MCU as electronic ballast control main control chip, the stronger big convenience of programmability, can lead to
The combination for crossing multidigit dial-up is arbitrarily set to change the state of MCU pins, to change the working condition of ballast.
It should be appreciated that the above-mentioned embodiment of the present invention is used not only for exemplary illustration or explains the present invention
Principle, without being construed as limiting the invention.Therefore, that is done without departing from the spirit and scope of the present invention appoints
What modification, equivalent substitution, improvement etc., should be included in the scope of the protection.In addition, appended claims of the present invention
Whole changes for being intended to fall into scope and border or this scope and the equivalents on border and
Modification.
