Abstract
The invention belongs to the field of a semiconductor lighting technique, disclosing an LED disconnecting and connecting circuit which is characterized by comprising multiple LEDs distributed in a row; the multiple LEDs distributed in a row is a parallel circuit comprising multiple series circuits after parallel connection; the LEDs are distributed in an equivalent interval mode among the LEDs connected to the series circuits; lamps controlled by one series circuit are scattered in each region of the integral lamp strip; and the difference of the display brightness is weakened and has no influence on the display quality and effect of the integral region even if the current passing each series circuit has difference.
Description
Technical field
The present invention relates to a kind of led circuit, belong to technical field of semiconductor illumination.
Background technology
Light emitting diode (Light Emitting Diode, be called for short LED) be widely used at present on a lot of products such as notebook computer, TV screen, neon light, need be responsible for the brightness demonstration in a zone by LED lamp bar under many situations, in the LED control circuit, usually adopt series circuit, as shown in Figure 2, many LED diodes are cascaded, with the circuit parallel connection of several series connection, be covered with whole viewing area then.In the circuit of parallel connection, tend to cause the size of current difference of passing through in each parallel line because of a variety of causes, when the electric current between these several the parallel branches is variant, the brightness of the paths of LEDs diode that electric current is big is strong, a little less than the brightness of the paths of LEDs diode that electric current is little, can cause the brightness irregularities of this zone demonstration, influence the display quality and the effect in whole zone.
Summary of the invention
Technical problem to be solved by this invention provides a kind of led circuit type of attachment, and the display brightness that overcomes whole viewing area of the prior art is inhomogeneous, the unfavorable problem of display effect.
For solving the problems of the technologies described above, the invention provides a kind of LED and jump connection circuit, comprise several and be distributed in LED light emitting diode in the delegation, it is characterized in that, described several are distributed in the parallel circuit that LED light emitting diode in the delegation is formed after by several series circuit parallel connections, equivalent LED light emitting diode spaced apart between the LED light emitting diode that links to each other in the described series circuit.
LED light emitting diode quantity is lacked one than the branch road quantity of described parallel circuit in every group of the described equivalent LED light emitting diode spaced apart.
Described LED jumps in the connection circuit and comprises delegation or multirow LED light emitting diode.
The beneficial effect that the present invention reached: the present invention adopts a kind of form of jumping connection circuit, the lamp that a series circuit is controlled is dispersed in each zone of whole lamp bar, even the electric current that passes through on every series circuit is variant, the strong and weak difference of the brightness of its demonstration also can be weakened, can not influence the display quality and the effect in whole zone.
Description of drawings
Fig. 1 is that LED of the present invention jumps the connection circuit schematic diagram;
Fig. 2 is a LED series circuit schematic diagram in the prior art.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
As shown in Figure 1, with 16 the LED light emitting diodes of arranged distribution in delegation is that example illustrates that LED of the present invention jumps the type of attachment of connection circuit, constitute parallel circuit by 4 parallel branches in the present embodiment, each parallel branch is formed by 4 LED light emitting diode series connection, LED1 every 3 LED light emitting diodes successively with LED5, LED9, the LED13 series connection, LED2 every 3 LED light emitting diodes successively with LED6, LED10, the LED14 series connection, LED3 every 3 LED light emitting diodes successively with LED7, LED11, LED15 series connection, LED4 every 3 LED light emitting diodes successively with LED8, LED12, the LED16 series connection.Be separated with LED2, LED3, LED4 totally 3 LED light emitting diodes between between LED coupled in series 1 and the LED5, be separated with LED6, LED7, LED8 totally 3 LED light emitting diodes between between LED coupled in series 5 and the LED9, reasoning successively, in like manner, be separated with LED3, LED4, LED5 totally 3 LED light emitting diodes between between LED coupled in series 2 and the LED6, be separated with LED7, LED8, LED9 totally 3 LED light emitting diodes, reasonings successively between between LED coupled in series 6 and the LED10.
The LED jumping connection circuit that constitutes according to above-mentioned type of attachment can be provided with corresponding line number as required.Preferred implementation is that every provisional capital constitutes LED jumping connection circuit according to above-mentioned form.This requires the quantity of the LED light emitting diode of every row can on average assign in each parallel branch just.
In other embodiments, when if the quantity of the LED light emitting diode that comprises in the delegation can not on average be assigned in each parallel branch, the mode that remaining LED light emitting diode is jumped connection circuit according to the LED of this journey can be continued to jump being connected to next line, and the like.That is to say, the connected mode that LED in the present embodiment jumps connection circuit is not limited only to single file, also the number row can be regarded as the first long row that links to each other of head and the tail or tail, jump the connected mode of connection circuit according to LED, to connect the LED circuit of LED that is together in series formation parallel circuit in parallel again every the LED of some light emitting diode.
The lamp that LED jumping connection circuit of the present invention is controlled a series circuit is dispersed in each zone of whole lamp bar, even the electric current that passes through on every series circuit is variant, the strong and weak difference of the brightness of its demonstration also can be weakened, can not influence the display quality and the effect in whole zone.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
