Description
Technical field
The present invention relates to a kind of LED light bars.
Background technology
Nowadays miscellaneous lamps and lanterns just become essential living electric apparatus in life and work, and LED light bar also exists
More and more places use, and traditional LED light bar is because use concatenated mode, and many times once one of lamp bead is damaged
Bad, may result in whole LED light bar can not use to scrap discarding, and LED light bar in parallel, due to various electronic devices
Cost and quality problems, once a lamp bead damage, also resulting in whole LED light bar can not use, and can not play double insurance
Effect, puts to no little inconvenience to normal life, production and work.
Invention content
Place that purpose of the invention is to overcome the shortcomings in the prior art, provides a kind of LED light bar.
In order to achieve the above object, the present invention uses following scheme：
A kind of LED light bar, including pcb board, it is characterised in that：The luminous lamp groups of two groups of LED are equipped in the pcb board, it is described
The LED lamp groups that shine include that several are sequentially connected in series luminescence unit together, are equipped on the pcb board and share cathode circuit,
The luminous lamp group input terminals of the LED are connected with shared anode, and cathode output end is equipped in the luminous lamp group output ends of the LED,
The luminescence unit includes the multiple LED lamp beads being connected in parallel, and LED lamp bead can be prevented by being parallel in the LED lamp bead side
The voltage stabilizing element of flicker.
A kind of LED light bar as described above, it is characterised in that the electrode input end setting is described negative in pcb board one end
The side for being located at electrode input end the same end in pcb board is arranged in pole output end, and the electrode input end connection is located at LED electroluminescent lamps
One end of group, the cathode output end connection are located at the other end of the luminous lamp groups of LED.
A kind of LED light bar as described above, it is characterised in that the electrode input end setting is described negative in pcb board one end
One end far from electrode input end in pcb board is arranged in pole output end, and the electrode input end connection is located at the one of the luminous lamp groups of LED
End, the cathode output end connection are located at the other end of the luminous lamp groups of LED.
A kind of LED light bar as described above, it is characterised in that the voltage stabilizing element is zener diode.
In conclusion advantage is the present invention compared with the existing technology：
The present invention is using shared cathode circuit, the luminous group of luminescence unit for being connected into an entirety that will be connected in parallel,
Voltage stabilizing element is increased between each luminous group, can not only be stablized because electric appliance excessively acting leads to electricity below in series circuit
Device voltage is unable to reach the problem of desirable value is to flicker, while two group connections that shine can also be solved institute by voltage stabilizing element
The problem of LED light bar can not be connected to because of lamp bead damage circuit in the group that shines, it is same using series system but more stable more reliable,
Manufacture it is also simpler than simple in parallel LED light bar, to provide safe efficient, reliable way in living, producing.
Description of the drawings
Fig. 1 is the stereoscopic schematic diagram of the present invention；
Fig. 2 is the circuit diagram of the present invention.
Specific implementation mode
The invention will be further described with specific implementation mode for explanation below in conjunction with the accompanying drawings：
A kind of LED light bar as shown in Fig. 1 to 2, including pcb board 1 are equipped with the luminous lamp groups of two groups of LED in the pcb board 1
The luminous lamp group 2 of 2, the LED is sequentially connected in series luminescence unit 3 together including several, is equipped with and shares on the pcb board 1
Cathode circuit, luminous 2 input terminals of lamp group of the LED are connected with shared anode, are equipped in luminous 2 output ends of lamp group of the LED
Cathode output end, the luminescence unit 3 include the multiple LED lamp beads 21 being connected in parallel, in the parallel connection of 21 side of the LED lamp bead
There is the voltage stabilizing element 22 that can prevent LED lamp bead 21 from flickering., two LED on pcb board shine lamp group 2 simultaneously using sharing anode
Input, two LED lamp beads 21 to form LED and shine the combination of group 2, have using luminescence unit 3 in parallel is cascaded
Effect avoids the problem that causing whole lamp bar that can not use because of a lamp bead damage.
Heretofore described electrode input end setting is in 1 one end of pcb board, and the cathode output end setting is in pcb board 1
Side in electrode input end the same end, electrode input end connection are located at LED and shine one end of lamp group 2, and the cathode is defeated
Outlet connection is located at LED and shines the other end of lamp group 2, positive and negative anodes connection LED shine group 2 be all in the same end of pcb board 1, this
Sample prescription just needs that the operation of circuit is arranged in the same end.
In 1 one end of pcb board, the cathode output end setting is remote in pcb board 1 for heretofore described electrode input end setting
One end from electrode input end, electrode input end connection are located at LED and shine one end of lamp group 2, and the cathode output end connects
It is connected in LED to shine the other end of lamp group 2, positive and negative anodes connect LED and shine group 2 respectively at the both ends of pcb board 1, are another in this way
Kind implementation, can facilitate the use connected up at lamp bar both ends.
