Abstract
The utility model discloses a boost converter suitable for low-voltage lamp string load connection. The boost converter comprises a lamp string composed of multiple LED lamps in series connections, wherein the lamp string is connected with an AC power supply through a transformer, the boost converter is connected at the middle of the lamp string in series, and the boost converter comprises a conversion chip. The boost converter provided by the utility model is more convenient to use for the users, reduces the mounting cost and the use cost for the users and has higher application value.
Description
Technical field
The utility model relates to electricity field, specifically a kind of boost converter that is suitable for low-pressure lamp string load connection.
Background technology
In the market and comparatively traditional lower voltage LED lamp string adopt nothing but magnetic transformer or new type electronic transformers to drive, the LED lamp string of the quantity that every string is certain (length) is mixed suitable magnetic or electronic transformer, user in use every cluster of lamps, ornamental string needs an AC voltage receptacle interface, make troubles so in use, and increased user's cost of use, even its main cause is the driving that enough large power is mixed in each driving, but with load lamp string (length) LED quantity still limited, because any electric wire is a constant impedance all, therefore can pressure drop be arranged at wire, when the lamp string is longer, certain pressure drop becomes and can't drive load or use by passive reduction electric current, so the power that drives can't maximize the use.
The utility model content
The purpose of this utility model provides a kind of boost converter that the load of low-pressure lamp string connects that is suitable for, and utilizes to greatest extent the power that drives.
Technical solutions of the utility model are as follows:
A kind of boost converter that is suitable for low-pressure lamp string load connection, include the lamp string of a plurality of LED lamp series connection, it is characterized in that: described lamp was ganged up transformer and was connected with AC power, be in series with boost converter in the middle of the described lamp string, described boost converter includes conversion chip, the pin seven series resistance Rsc of described conversion chip also draw terminals as the input of conversion chip, the anodal connection of described resistance R sc capacitor C 1 anodal and ground connection, the pin six of described conversion chip connects the positive pole of capacitor C 1, pin four ground connection of described conversion chip, the pin three of described conversion chip connects the anodal and ground connection of capacitor C 3, draw the two-way wiring behind the pin eight series resistance R3 of described conversion chip, the negative pole of one road contact resistance Rsc, the pin one of access conversion chip behind the series inductance L of another road, the pin two of described conversion chip is drawn the two-way wiring, ground connection behind one tunnel series resistance R4, another road connecting triode TR base stage, described triode TR grounded emitter, described triode TR collector electrode is drawn the two-way wiring, one the tunnel connects the inductance L negative pole, another road connects diode D1 positive pole and draws terminals as the output of conversion chip, the pin five of described conversion chip is drawn the two-way wiring, one tunnel series resistance R1 ground connection, another road series resistance R2 accesses the output of described conversion chip, and the negative pole of described diode D1 connects the anodal and ground connection of capacitor C 2.
Described boost converter output voltage is constant to be 30V.
The LED load needs certain driving voltage, although along with LED quantity increases and the wire lengthening, pressure drop increases on the wire, but the connection by boost converter is elevated to the voltage that reduces the LED lamp string load driving voltage that needs, as long as be no more than the power of driving power, just multi-string LED can be prolonged connection, therefore many cluster of lamps, ornamental string can use a driving power, uses an AC power supplies interface.
The beneficial effects of the utility model:
It is convenient that the utility model is installed and used the user, also reduced user's cost of installation and use, has very strong using value.
