The utility model discloses a cuttable single-layer light emitting diode (LED) circuit board and LED lamp bead units; the cuttable single-layer LED circuit board comprises a single-layer circuit board which is provided with a plurality of LED lamp bead units; the LED lamp bead units are provided with four pairs of power supply leads, and each of the leads comprises a positive lead and a negative lead; the positive leads of the four pairs of power supply leads are simultaneously connected with the positive electrodes of the LED lamp beads, and the negative leads are simultaneously connected with the negative electrodes of the LED lamp beads. Through the circuit design on LED, the LED lamp beads have four pairs of power supply leads which are mutually connected through the circuit board, and the LED lamp bead units on the circuit board are equally connected in parallel, so that the function of optionally cutting the LED circuit board is achieved, and the production cost is greatly reduced; and because the LED lamp bead units are connected in parallel, the maximum power supply voltage is just 12V, so that the safety of the product is greatly improved.
Description
Technical field
The utility model relates to a kind of circuit board, relates in particular to a kind of individual layer led circuit plate and LED lamp pearl unit of cutting.
Background technology
LED lamp plate producer has designed the LED lamp plate of large tracts of land monoblock for lighting fields such as lamp affixed to the ceiling, large-area area sources on the market, and this type of lamp plate connects at circuit and adopts three kinds of structures: the first is that three lamp pearls series windings are one group, and some groups are carried out and connect; The second becomes one group, then per three groups or four groups connections of contacting again for several lamp pearls and after connecting; The third is the whole series windings of 20 to 100 lamp pearls, adopts constant-current switch power source, capacitance-resistance power supply or powers with the high drive mode.
Above-mentioned LED lamp plate has following obvious deficiency:
At first be that these type of plank great majority can not cut, any type of cutting all will destroy the connection line of LED lamp pearl on the plank.This class lamp plate all is predetermined in advance to producer, and so not only cost is high, and the cycle of making is longer.Although the plank that also has part to cut, whenever the minimum unit that cuts down is exactly an independent used lamp bar, but this cutting mode must cut in strict accordance with the line of cut of plank design initial stage regulation, otherwise will destroy the independence of minimum unit, affect normal operation thereby cause plank part or integral body to break down.And in case there are internal damage, possible circuit board just to need monoblock to change.
Secondly, existing LED power supply all is the high drive mode, also can bring the hidden danger of electric shock.
The utility model content
The purpose of this utility model provides a kind of individual layer led circuit plate that cuts, and can cut arbitrarily according to demand, and the led circuit plate after the cutting all can independently be worked.
The utility model also provides a kind of LED lamp pearl unit, makes the described enterprising enforcement usefulness of individual layer led circuit plate that cuts of its collocation.
The utility model adopts following technical proposals:
A kind of individual layer led circuit plate and LED lamp pearl unit of cutting, comprise the single layer board that is provided with a plurality of LED lamp pearls unit, described each LED lamp pearl unit is provided with four pairs of power supply lead wires, every a pair of lead-in wire comprises that one is just going between and a negative lead-in wire, just going between in described four pairs of power supply lead wires all connects the positive pole of LED lamp pearl, negative lead-in wire all connects the negative pole of LED lamp pearl, and the every a pair of power supply lead wire of described LED lamp pearl unit just, negative lead-in wire respectively by on the single layer board cover in copper cash and the adjacent LED lamp pearl unit a pair of power supply lead wire just, negative lead-in wire is connected.
Described four pairs of power supply lead wires are separately positioned on four sides of LED lamp pearl unit.
Be provided with the LOGO for the identification direction on the described LED lamp pearl unit.
Described a plurality of LED lamp pearls unit according to LOGO with the formal distribution of matrix on single layer board.
The utility model is by carrying out circuit design to led circuit, make each LED lamp pearl unit have four groups of power supply lead wires, interconnect by circuit board between the power supply lead wire of different LED lamp pearl unit, LED lamp pearl unit all on the circuit board is all constituted to be connected in parallel, thereby realize the function that the led circuit plate can cut arbitrarily, greatly reduced production cost; And because LED lamp pearl unit is connected in parallel the highest 12V that only needs of supply voltage, the security that has greatly improved product.
Description of drawings
Fig. 1 is the utility model circuit connection diagram;
Fig. 2 is the schematic diagram of LED lamp pearl described in the utility model unit.
The specific embodiment
As depicted in figs. 1 and 2, a kind of individual layer led circuit plate and LED lamp pearl unit of cutting, comprise the single layer board 30 that is provided with a plurality of LED lamp pearls unit 10, described LED lamp pearl unit 10 is provided with four pairs of power supply lead wires, every a pair of lead-in wire comprises that one is just going between and a negative lead-in wire, just going between in described four pairs of power supply lead wires all connects the positive pole of LED lamp pearl 9, negative lead-in wire all connects the negative pole of LED lamp pearl 9, and the every a pair of power supply lead wire of described LED lamp pearl unit just, negative lead-in wire respectively by a pair of power supply lead-in wire that covers copper cash and adjacent LED lamp pearl unit on the single layer board just, negative lead-in wire is connected.
Described four pairs of power supply lead wires are separately positioned on four sides of LED lamp pearl unit.
Be provided with the LOGO for the identification direction on the described LED.LOGO is a unfilled corner 15 in the upper left corner, LED lamp pearl unit in the present embodiment, is used for the welding direction of each LED lamp pearl unit of identification.Also can adopt other pattern, indications etc., no longer narrate at this.
Described a plurality of LED lamp pearls unit with the formal distribution of matrix on single layer board.Interconnect by covering copper cash between a plurality of LED lamp pearls unit on the single layer board 30, in the present embodiment, wherein cover copper cash 20 and cover copper wire for positive pole, cover copper cash 21 and cover copper wire for negative pole, four groups of power lines that each LED lamp pearl element solder can make any one LED lamp pearl unit after on the single layer board 30 are connected with the power supply lead wire of the LED lamp pearl unit adjacent with it with the negative copper cash 21 that covers by just covering copper cash 20 respectively, LED lamp pearl unit on the single layer board 30 is connected in parallel all like this, this moment any a pair of power line pin plugged, other LED lamp pearl unit also all can be normally luminous.That has so just realized single layer board can cut arbitrarily characteristic, because in parallel circuit, cut arbitrarily rear remaining circuit and still be parallel circuit, do not destroy its circuit supply characteristic, same when single led lamp pearl unit damages, can not affect the use of other LED lamp pearl unit yet.
Described a plurality of LED lamp pearls can arrange at most 4 LED lamp pearls 9 in the unit, and described 4 LED lamp pearls 9 are connected in series.Because power supply is different with LED lamp pearl specification, if use the supply voltage of 12V to power, when the withstand voltage of LED lamp pearl was 3V, we can regulate the lamp pearl quantity in the LED lamp pearl unit, and it is used, and reach required withstand voltage.Do not affect so equally its arbitrarily cutting property, and use magnitude of voltage to be generally 3V, 9V, 12V, supply voltage is low, is worth 36V well below the human safety voltage.Improved the security of product.
