Abstract
The utility model belongs to the technical field of semiconductor illumination, and discloses an LED jumping-connecting circuit, which comprises a plurality of LEDs distributed on a line. The LED jumping-connecting circuit is characterized in that the LEDs distributed on the line are in a parallel circuit consisting of a plurality of series circuits in parallel connection, and the LEDs are equivalently distributed between each two connected LEDs in the series circuits at intervals. Lights controlled by one series circuit are scattered in areas of an integral light bar, even if current passing through the series circuits are different, displayed brightness strength differences can also be reduced, and display quality and effect of an integral area cannot be affected.
Description
Technical field
The utility model relates to a kind of led circuit, belongs 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 in the utility model 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 utility model provides a kind of LED to 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 utility model reached: the utility model 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 the utility model LED 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 utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, with 16 the LED light emitting diodes of arranged distribution in delegation is that example illustrates that the utility model LED 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 utility model 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 utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection domain of the present utility model.
