Description
Technical field
The present invention relates to supply unit, especially a kind of LED gear regulated power supply device.
Background technology
At present, in LED constant-current driving power supply, it is all the device of not setting online Modulating Power, existing LED constant-current supply is all that the fluorescent tube for same model matches and uses adjusting electric current, use power supply to bring certain limitation to the fluorescent tube of product different batches, particularly in process in batches, for example: the fluorescent tube that has 12W, 14W fluorescent tube, traditional LED power supply is with regard to necessary coupling of carrying out electric current according to these two kinds of fluorescent tubes, what in the process of using, two kinds of power supplys can not be mutual is mixed, that is to say that a kind of power supply can not be used on two kinds of fluorescent tubes, the words of using, parameter and data are joined in necessary also will readjusting, use very inconvenient.
In the place of the large-scale long-time electricity consumption in supermarket, fluorescent tube just has certain light decay to LED lamp long afterwards service time, change cumbersome, and cost of idleness.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of LED gear regulated power supply device, can be applicable to the LED lamp of various models, and simple in structure, and applied range has reduced production cost simultaneously.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of LED gear regulated power supply device is provided, comprise field effect transistor, channel selector, a plurality of resistance, inductance, electric capacity, diode, the source electrode of field effect transistor is connected with a plurality of resistance, other one end of a plurality of resistance is connecting path switch respectively, the other end of channel selector connects first input end mouth, the grid of field effect transistor is connected with first input end by resistance, the anodic bonding of drain electrode and diode, the negative electrode of diode is connected with the second input, electric capacity one end connects the negative electrode of diode, the other end is connected the anode of diode with the other end of inductance, electric capacity two ends be equipment the first output and the second output.
In a preferred embodiment of the present invention, described a plurality of resistance is six.
In a preferred embodiment of the present invention, described on-off switch is SW-ZIP8.
Implement, after above technical measures, to there is following technique effect.
1. change the type of drive of matching single fluorescent tube for current single power supply, simple in structure, range of application is more extensive, has virtually reduced production cost.
2. power supply just can be suitable for the LED fluorescent tube of 8W-20W, uses convenient.
3. the power of can well secondary adjusting power supply increases the lighting tube brightness of light decay, saves the expense of changing fluorescent tube.
