Description
Technical field
The utility model is related 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.
Utility model content
The purpose of this utility model is to overcome shortcomings in the prior art, provide a kind of LED light bar.
In order to achieve the above object, the utility model 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 utility model compared with the existing technology：
The utility model is using shared cathode circuit, the luminous list for being connected into an entirety by luminous group be connected in parallel
Member, voltage stabilizing element is increased between each luminous group, after can not only stablizing because the excessive acting of electric appliance causes in series circuit
Face electrical voltage is unable to reach the problem of desirable value is to flicker, while voltage stabilizing element can also solve two group connections that shine
Where shine LED light bar in group the problem of can not being connected to because of lamp bead damage circuit, equally using series system but it is more stable more
Reliably, 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 utility model；
Fig. 2 is the circuit diagram of the utility model.
Specific implementation mode
Explanation and specific implementation mode are further described the utility model 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
