     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0014]    Referring to  FIG. 1  to  FIG. 3 , parts of the serial light-emitting light according to the present invention and the assembly thereof are shown.  FIG. 1  is a schematic view of the appearance of the serial light-emitting light structure of the present invention.  FIG. 2  is an exploded diagram of the serial light-emitting light structure of the present invention.  FIG. 3  is a sectional view of the serial light-emitting light structure of the present invention. The serial light-emitting light structure of the present invention comprises an outer cover  1 , an outer sleeve  2 , and a circuit panel  6 . 
         [0015]    The circuit panel  6  is mounted with a plurality of the LED lights  7  with a plurality of notches on the edge corresponding respectively to the LED lights  7 . The activation flow of the LED lights  7  are regulated by the control circuit of the serial light-emitting light. 
         [0016]    The outer sleeve  2  is a concaved cap, having a top surface  21  at the bottom with a wire gathering aperture  22  in the center, wherein the aperture  22  provides a common outlet for the wires of the LED lights  7  connected to the circuit panel  6 . The outer sleeve  2  has a clip hook  4  provided on both sides of the peripheral annular surface, and a clasp hook  3  provided beside both sides of the wire gathering aperture  22  on the top surface  21 . The clasp hooks  3  reversely correspond to each other, and the clip hooks  4  symmetrically correspond to each other. The outer sleeve  2  further has a slot  25  for placing the circuit panel  6  on the inside surface thereof. A first engaging part  24  is connected to the outer cover  1 , wherein the first engaging part  24  is a groove. The slot  25  for placing the circuit in is separated from the top surface  21  at a distance so as to provide a space for gathering the wires for the LED lights  7  on the panel  6 . In addition, the opening  23  of the outer sleeve  2  is designed with an arced surface. 
         [0017]    The outer cover  1  has a round opening  11  with a second engaging part  12  thereon, which is a ridge. The second engaging part  12  is engaged with the first engaging part  24  of the outer sleeve  2 , so that the outer cover  1  and the outer sleeve  2  are interlocked. Therefore the circuit panel  6  is prevented from being easily detached therefrom while the light emitted by the LED lights  7  can pass through the outer cover  1 . 
         [0018]    According to the present embodiment of the serial light-emitting light structure of the present invention, the outer sleeve  2 , the wire gathering aperture  22 , the circuit panel  6 , outer cover  1 , and the round opening  11  of the outer cover have been described as, but not limited to, being round. Various modifications and alterations, where the first engaging part  24  of the outer sleeve  2  is engaged with the second engaging part  12  of the outer cover  1 , the outer sleeve  2  is disposed with the circuit panel  6  inside and the wires for LED lights  7  are gathered and outlet from the wire gathering aperture  22 , should be included in the scope of the present invention. Therefore, the outer sleeve  2 , the wire gathering aperture  22 , the circuit panel  6 , the outer cover  1 , and the round opening  11  of the outer cover can be made into either planar or solid elements of a square, a triangle, or any other shape. 
         [0019]    According to the present embodiment, the second engaging part  12  is an engaging ridge, and the first engaging part  24  is an engaging groove, which however, is by no means limiting of the present invention. Any equivalent means for engaging the ridge and the groove so that the opening  11  of the outer cover can be engaged to the outer sleeve  2  without undesired detachment shall fall into the scope of the present invention. Thus, the first engaging part  24  may be a ridge, while the second engaging part  12  may be a groove, or any other combination of an engagement mechanism. 
         [0020]    The serial light-emitting light of the present invention has light changes, and therefore, a control circuit for the serial light-emitting light is further provided herein, to explain the operation of the LED lights  7 , as shown in  FIG. 4 , which is a block diagram of the control circuit for the serial light-emitting light of the present invention. 
         [0021]    The control circuit for the serial light-emitting light comprises a control chip  610 , a red light module  620 , a blue light module  630 , a green light module  640 , a power supply unit  670 , and a variable resistor  685  for controlling the operation time of the control circuit. The power supply unit  670  provides DC power via a pin  671  and AC power via a pin  675  to the control chip  610 , and is further grounded via a pin  673 , wherein the control chip  610  further controls the operation order and light emission of the red light module  620 , the blue light module  630 , and the green light module  640 . 
         [0022]    The control chip  610  controls the operation of the red, blue, and green light modules  620 ,  630  and  640  respectively through pins  621 ,  631  and  641 . The red, blue, and green light modules  620 ,  630  and  640  all have the other end grounded. 
         [0023]    The control chip  610  further provides pins  651  and  653  as control switch points, so that the user can alter the operating circuit of the LED lights  7  by the first switch  655 , that is, the first swich  655  controls the LEDs  7  whether to operate, and the emitting lights of the LEDs  7  include two or three kinds of colors defined according to swiching the first switch  655 . In other words, when the first switch is switched to the pin  651 , the colors of two of the red light module  620 , the blue light module  630  and the green light module  640  can be changed by the control chip  610 , and that of the other one remains unchanged. 
         [0024]    As above, pins  661  and  663  enable the control chip  610  to switch the operation mode of the LED lights  7 , i.e., the mode of the LED lights  7 , through the second switch  665 . For example, if pin  661  controls the red, blue or green light module  620 ,  630 , or  640  to flash alternatively, pin  663  controls the red, blue or green light module  620 ,  630 , or  640  to lighten or dim gradually. As the second switch  665  is switched to the pin  661  so that the pin  661  is grounded, the red, blue or green light module  620 ,  630  or  640  generates alternatively and continuously flashing lights. As the second switch  665  is switched to the pin  663  so that the pin  663  is grounded, the red, blue or green light module  620 ,  630  or  640  generates gradually dimming or lightening changes as controlled by the control chip  610 . 
         [0025]    As the variable resistor  685  is connected to the pins  681  and  683 , the operation time of the red, blue or green light module  620 ,  630  or  640  can be controlled through the control chip  610 , by varying the resistance value of the variable resistor  685 . 
         [0026]    The control circuits in the red light module  620 , the blue light module  630  and the green light module  640  are as shown in  FIG. 5 , which is a schematic view of the LED light circuit in the control circuit of the serial light-emitting light according to the present invention. 
         [0027]    The red light module  620  comprises variable resistors  623  and  629 , a control transistor  625  and a red LED light  627 . The blue light module  630  comprises variable resistors  633  and  639 , a control transistor  635 , and a blue LED light  637 . The green light module  640  comprises variable resistors  643  and  649 , a control transistor  645 , and a green LED light  647 . 
         [0028]    If the first switch  655  is switched to the pin  651  so that the pin  651  is grounded, the control chip  610  will control the operation of the red, blue and green light modules  620 ,  630  and  640 . Thus, if the control transistor  625  is connected to a constant voltage power source VCC, the control chip  610  may send a signal to the control transistor  625  through the pin  621  to turn the transistor  625  on, and thereby to further turn on the red LED light  627 . The switching direction of the first switch  655  can be predetermined. 
         [0029]    Also, the control chip  610  may send a signal to the control transistor  635  through the pin  631  to turn the transistor  635  on, and thereby to further turn on the blue LED light  637 ; or send a signal to the control transistor  645  through the pin  641  to turn the transistor  645  on, and thereby to further turn on the green LED light  647 . 
         [0030]    While the operating time of each LED light can be regulated by the variable resistor  685 , the operation changes of each LED light can be controlled by switching the second switch  665 . 
         [0031]    Though the LED light module of the present invention has employed an LED light, two variable resistors and a control transistor to achieve the operation and time order of the LED light module, it should not be deemed as limiting the present invention. Any combination of circuits, where the resistors, the transistors and the LED lights are assembled and the control chip  610  can be used to send a signal to turn the transistors ON and thereby the LED light ON, shall fall into the scope of the present invention. Thus, the variable resistors  623 ,  629 ,  633 ,  639 ,  643  and  649  can be replaced by fixed resistors, and the number of the red, blue and green LED lights  627 ,  637 , and  647  and the elements corresponding to each LED light can be set or modified according to the requirements of the user. 
         [0032]      FIG. 6  is a schematic view of the assembled serial light emitting string light of the present invention. The assembled serial light emitting string light are serially connected using wires  5  connected to the LED lights  7 , so that each light can be connected in serial as a long string, which can be used for Christmas decorations by creating a cheerful atmosphere with varied luminance of the lights. Furthermore, each light can be put up onto the tree by hanging the clip hooks  4  on the peripheral of the outer sleeve  2  onto small braches, which makes decorating much easier. Meanwhile, with the engaging mechanism of the present invention, the lights can be prevented from undesired detaching and are easy to assembly and disassembly. 
         [0033]    The attached drawings are for reference only and by no means limiting of the scope of the present invention. The above embodiment is only a preferred embodiment of the present invention which should not be deemed as to limit the claims of the present invention. Any equivalent modification or alteration of the specification and drawings herein shall be included in the scope of the present invention, as defined by the claims.
