Abstract
The utility model provides a kind of no soft light bar of stroboscopic LED high-voltage.Including multiple LED series units being connected in parallel, as soon as rectification function is come in each LED series unit, does not need traditional power supply due to being connected in series with rectification unit in every LED series unit, it, can be with indefinite extension not by the constraint of conventional power source power；Again due to being also in series with constant current chip in LED series unit and being connected in parallel to filter capacitor, so LED series unit also comes with constant current and filter function, voltage fluctuation is substantially reduced, eliminates light stroboscopic, is conducive to protection eyes.
Description
Technical field
The utility model relates to a kind of LED illumination lamps, more particularly to a kind of no soft light bar of stroboscopic LED high-voltage.
Background technique
Due to LED can only one-way conduction, and have nonlinear C-V characteristic, the electric main of 220V cannot be directly connected to
It uses.Existing high-voltage LED light bar is typically arranged with power supply, has rectifier bridge stack in power supply, 220V alternating current is switched to direct current.
Include multistage flexible circuit board in light bar, includes being serially connected in by multiple LED and resistance on each section of flexible circuit board
LED series unit coats the circuit board and the PVC flexible glue crust of LED, the positive and negative power supply line extended along light bar length direction
Road.Each section of flexible circuit board of light bar is connected in parallel to the positive and negative power supply route, thus comprising one section of flexible circuit board
Lamp belt segment constitute one can cut cells, each can may include one or more LED series connection being connected in parallel in cut cells
Unit, the operating voltage of every LED series unit are 220V.In this way high-voltage LED light bar can minimum cost be connected to city
Electricity uses.Since alternating current is after rectifier bridge simple process, still there is certain fluctuation, to cause light bar with high stroboscopic
It is bright, there is nocuity to eyes.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of soft light bar of no stroboscopic LED high-voltage and using should
The soft light bar of the LED high-voltage of circuit.
The utility model solves technological means used by its technical problem: a kind of no soft light bar of stroboscopic LED high-voltage, packet
Multistage flexible circuit board is included, one is included at least on each section of flexible circuit board and is connected by the LED that LED and resistance are serially connected in
Unit coats the circuit board and the PVC flexible glue crust of LED, the power circuit extended along light bar length direction, each section of flexibility
Circuit board is connected in parallel to the power circuit by lead point, and LED series unit front end is connected in series with rectification unit,
LED series unit rear end is connected in series with constant current chip, and the LED series unit is also connected in parallel to filter capacitor.
The beneficial effects of the utility model are: whole due to being connected in series with patch in LED series unit in the utility model
Device is flowed, rectification function is just come in each LED series unit, traditional external power supply is not needed, not by conventional power source function
The limitation of rate, light bar overall length can be with indefinite extensions；Again due to being also in series with constant current chip in LED series unit and being connected in parallel to
Filter capacitor substantially reduces voltage fluctuation so LED series unit also comes with filter function and constant current function, eliminates light
Stroboscopic is conducive to protection eyes.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of A-A section in Fig. 1；
Fig. 3 is the circuit structure diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
With reference to Fig. 1 and Fig. 2.A kind of no soft light bar of stroboscopic LED high-voltage, including the flexible circuit board 1 that multistage is connected in parallel, weldering
LED2 and resistance 22 on the circuit card 1 is met, the flexible core wire 3 of the circuit board 1 is coated.3 two sides of core wire are embedded with along light bar
The power circuit 4 that length direction extends.The circuit board 1 passes through lead 5 and is connected in parallel respectively with power lead 4.Outside core wire 3
It is coated with flexible PVC glue crust 6.
With reference to Fig. 3, every two LED2 composes in parallel simultaneously gang mould group 21, multiple described and gang mould groups 21 and electricity on circuit board 1
Resistance 22, which is connected in series, constitutes LED series unit 20.It is single as rectification that 20 front end of LED series unit is connected in series with patch rectifier
The input terminal of member 23, rectification unit 23 is connected in parallel with power lead 4 respectively by lead 5.The series connection of 20 rear end of LED series unit
It is connected with constant current chip 24, LED series unit 20 is also connected in parallel to filter capacitor 25, and the filter capacitor 25 is also connected in parallel
There is resistance 26.The operating voltage of the LED series unit 20 can not need in this way decompression i.e. slightly above or equal to line voltage
It can access 220V high pressure alternating current.
A LED series unit 20 can be set on each section of flexible circuit board 1, multiple parallel connections also can be set even
The LED series unit 20 connect, when multiple LED series units 20 are arranged, every LED series unit 20 all as elucidated before that
Sample, independent series rectifier unit 23 and constant current chip 24, parallel filtering capacitor 25 and resistance 26.
Since rectification unit 23 is connected in series in the utility model in LED series unit 20, each LED series unit
Rectification function is just come in 20, does not need traditional power supply, it, can be with indefinite extension not by the constraint of conventional power source power；Again
Due to being also in series with constant current chip 24 in LED series unit 20 and being connected in parallel to filter capacitor 25, so LED series unit 20
Constant current and filter function are also come with, voltage fluctuation is substantially reduced, eliminates light stroboscopic, is conducive to protection eyes；Again due to filtering
Capacitor 25 is also connected in parallel to resistance 26, and capacitor 25 can be allowed to discharge rapidly when turning off the light, and shortens LED sunset glow, allows when turning on light
LED is lighted rapidly, shortens delay of turning on light.
The description of the above specific embodiment is only the utility model preferably embodiment, is not offered as practical to this
The limitation of novel protected content, it is any in the utility model intended spirit, it can be obtained by the normal reasoning of those of ordinary skill
Technical solution be all the protection scope of the utility model.
