Description
Technical field
The present invention relates to the driving means of a kind of Switching Power Supply, be specifically related to a kind of non-isolation type high-voltage LED Switching Power Supply
Driving means.
Background technology
Traditional Switching Power Supply is divided into primary side and secondary end, is provided with light-coupled isolation device between primary side and secondary end
Feed back as signal, ensured power supply high pressure and secondary and the safety of shell mechanism to a certain extent, but had the disadvantages that
1, the shell mechanism isolation of secondary end and light fixture is inadequate, resistance to forces down, and the electrostatic easily causing LED light source component damages
Bad；
2, carry out isolating the conversion efficiency reducing power supply between the primary and secondary end of power supply；
3, back coupling integrated circuit is complicated, and design cost is high, and reliability also decreases.
Summary of the invention
In order to solve problems of the prior art, the present invention provides a kind of non-isolation type high-voltage LED Switching Power Supply
Driving means, centre does not set sealing coat so that power-efficient is greatly promoted.
To this end, the present invention provides the driving means of a kind of non-isolation type high-voltage LED Switching Power Supply, including circuit board and shell
Structural member, arranges sealing coat between described circuit board and shell mechanism part.
Preferably, described sealing coat uses ceramic substrate material isolation.
Further, described circuit board is made up of with independent constant-current source independent constant pressure source.
Preferably, described independent constant pressure source is the Width funtion booster circuit of exportable steady voltage source.
Preferably, described independent constant-current source uses the constant current technology that thermal source separates, including peripheral hardware power MOS pipe and high accuracy
Constant-current source.
Preferably, described independent constant-current source built-in temperature protection circuit.
Compared with prior art, not setting sealing coat in the middle of the present invention, power-efficient is greatly promoted；Need not feedback and feedback electric
Road so that circuit reduction；Sealing coat is located between whole circuit board and shell mechanism part, and uses ceramic substrate material, pressure
Height, pyroconductivity are good；The constant current technology using thermal source to separate, can effectively avoid the current precision that Yin Re or voltage pulsation cause
Device failure and load light source that deviation, high pressure cause damage；Independent constant pressure source separates with independent constant-current source so that be in well,
Independent constant-current source both also can be set together by independent constant pressure source with light source arrangement at one piece, both protected while motility is strong
Himself not clothing damage and also protect LED light source component.
Accompanying drawing explanation
Fig. 1 is the sectional view of the present invention；
Fig. 2 is the structured flowchart of circuit board in the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the invention are described in detail.
Referring to Fig. 1 and Fig. 2, the present invention provides the driving means of a kind of non-isolation type high-voltage LED Switching Power Supply, including electricity
Road plate 2 and shell mechanism part 1, arrange sealing coat 3 between described circuit board 2 and shell mechanism part 1.
Described sealing coat 3 uses ceramic substrate material to isolate.
Described circuit board 2 is made up of with independent constant-current source 5 independent constant pressure source 4.
Described independent constant pressure source 4 is the Width funtion booster circuit 5 of exportable steady voltage source.
The constant current technology that described independent constant-current source 5 uses thermal source to separate, including peripheral hardware power MOS pipe 6 and high precision constant current
Source 7.
The present invention uses the constant current technology that thermal source separates, peripheral hardware power MOS pipe 6 to combine with high precise current source 7, power
Metal-oxide-semiconductor 6 is not the driving of high precise current source 7, is not controlled by high precise current source 7, and effect is to undertake heat and pressure.
High precise current source 7 maintains constant current accuracy all the time, and size of current is to be obtained by varying number parallel connection.
High precise current source 7 built-in temperature protection circuit 8, it is not necessary to any peripheral components, temperature output safety value is automatic
Lower output electric current.
This invention output voltage is a kind of fixed form, with light source matching voltage value, it is not necessary to adjust.
To sum up, not setting sealing coat in the middle of the present invention, power-efficient is greatly promoted；Need not feed back feedback circuit so that electricity
Road simplifies；Sealing coat is located between whole circuit board and shell mechanism part, and uses ceramic substrate material, pressure height, conduction of heat
Rate is good；The constant current technology using thermal source to separate, the current precision that can effectively avoid Yin Re or voltage pulsation to cause deviates, high pressure
The device failure caused and load light source damage；Independent constant pressure source separates with independent constant-current source so that be in well, independent constant-current source
Both also can be set together by independent constant pressure source with light source arrangement at one piece, while motility is strong, both protected himself not
Clothing damages and also protects LED light source device.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto,
Any those familiar with the art in the technical scope that the invention discloses, according to technical scheme and
Inventive concept equivalent or change in addition, all should contain within protection scope of the present invention.
