The specific embodiment

Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.

As shown in Figure 1 and Figure 2, the invention provides a kind of LED lamp string, it comprises at least two LED pedestal 108 and connection lines; For example, connection line can comprise a positive source line 104, a power-polar curve 106 and a signal control line 105; On LED pedestal 108, at least two LED are set, such as LED101 etc., be more preferably, on the pedestal, the number of LED can be selected arbitrarily between 3 to 10, can also be above 10; LED101 is fixedly installed on the LED pedestal 108, and forms a display unit 102 with 108 encapsulation of LED pedestal, thereby makes the annexation of LED101 and LED pedestal 108 more firm.

One positive source line 104, at least one power-polar curve 106 and at least one holding wire 105 are set on the LED pedestal 108 at least; The anodal pin of LED101 is electrically connected with positive source circuit 104, and the negative pole pin of LED101 is electrically connected with power cathode circuit 106.Positive source line 104 is connected with the power-polar curve and is connected with the both positive and negative polarity of power supply respectively, and being used for provides voltage to LED lamp string.Signal control line 105 1 ends are connected with control system, and the other end is connected with control circuit 110 on the display unit 102; Control system transmits control signal, and control signal is by the transmission of signal controlling circuit, and control circuit 110 is according to the control signal of transmission, the LED101 on the control display unit 102.The positive source line, power-polar curve and the signal control line that arrange on the display unit 102 are used for carrying out cascade with the asynchronous interface of the respective lines of next display unit.

Between positive source line 104 and control circuit 110, be provided with a constant-current drive circuit 109, constant-current drive circuit 109 1 ends are connected with positive source line 104, and the other end is connected with control circuit 110.Constant-current drive circuit 109 is mainly used in alternating voltage is converted to constant-current supply.Control circuit 110 is according to the control signal of signal control line 105 transmission, and the constant current of constant-current drive circuit input, drives each LED on the control LED lamp string, such as LED101.

And for example, LED lamp string of the present invention can also comprise system's outer cover and an external circuits unit 112.Form at least one display unit 102 of LED lamp string and be contained in system's outer cover, system's outer cover shields to connected system, as: can play the effects such as waterproof and dustproof.External circuits unit 112 is used for realizing the outside line of connected system and being communicated with of internal wiring.External circuits unit 112 comprises positive source line, power-polar curve and signal control line at least.

Another example is, in the LED lamp string of the present invention, the LED pedestal arranges three to ten LED, described LED LED pedestal arrangement mode comprise at least following arrangement mode one of them: rods arranged in horizontal line, cross arrangement, annular arrangement or customized graphics.Customized graphics comprises various moulding, for example star, mouse-shaped etc.

In the LED lamp string of the present invention, each LED is uniformly set at the edge on described LED pedestal 108 at least one planes.For example, the a certain plane of described pedestal 108 is square, it is one square that each LED evenly is distributed as, be arranged on the edge of square LED pedestal upper surface, be used for strengthening the decorative hair light effect of LED, similarly, according to using needs, when a certain plane of described pedestal was annular, each LED also can annular arrangement be arranged on the edge of pedestal upper surface.And for example, when a certain plane of described pedestal is the five-pointed star shape, in order to increase brightness, can be on LED pedestal 108 the edge setting on plane and the LED that its profile is complementary.Can obtain better visual effect like this.

An example can also be, the a certain plane of described pedestal is circular, another plane is regular pentagon, and a circle LED then can evenly be set in the edge of circular flat, and the edge on the regular pentagon plane evenly arranges five, nine, ten, 14,15 or more LED.

In the LED lamp string of the present invention, at the center at least one plane of LED pedestal at least one LED is set also.For example, a certain plane of LED pedestal 108 is five-pointed star shapes, then can one LED be set at the pentalpha center on this plane; Five LED that are arranged in regular pentagon perhaps are set, make its decoration more colorful, visual effect is better.

As shown in Figures 2 and 3, be provided with pedestal 108A and pedestal 108B, when the signal control line that arranges on the display unit 102 is that control circuit 110 is the single line control circuit when forming a bars control circuit by single line.Single line control circuit 110 carries out transfer of data with serial mode, four traditional holding wires is integrated, thereby realize forming all signals of a bars control line 105 transmission by single line.Single line control circuit 110 comprises: signal analyse block 201, signal decoding module 202 and Signal coding module 203, the module that reports an error 204 and pulse width modulation (PWM) module 205.
