Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the invention  
         [0002]     The present invention relates to a type of strip light structure, particularly to one having a matrix electrical circuit and flexibility for free bending.  
         [0003]     2. Description of the Prior Art  
         [0004]     Conventionally, a display device made of LED is in the shape of a plane. Such display device has the effect of display, but due to its plane-shaped configuration, it can not be bent in its application. For example, a plane-shaped LED display device is not suitable for installation at the corner of house eaves, or at the corner of an advertising signboard, or the corner of a car body.  
         [0005]     However, in daily living, there is indeed the need for the installation of a light-emitting devices at corners for the purpose of caution or identification. Therefore, providing a bendable light-emitting device is satisfactory for practical needs, the light in strip structure is the best option for above applications. But generally, the light-emitting devices on a strip light are arranged in a single line. So, the light-emitting devices in the strip light structure are serially connected. But such type of serially connected circuit not only requires a higher voltage to enable normal functioning of each light-emitting device but also when one of the light-emitting devices in strip light failed will cause entire light fail. Therefore, such structure is not an ideal type.

         [0007]     The present invention has a bendable insulating strip, on which are arranged a plurality of strip-shaped conductive units, then a plurality of light-emitting devices(such as Light Emitting Diode) disposed on the plurality conductive units, thereby forming a matrix electrical circuit.  
         [0008]     The arrangement of the plurality of conductive units are in two methods. One is to install a plurality of staggered conductive units into two lines on same surface of an insulating unit, or, the plurality of conductive units are arranged into one line with an interval between two neighboring conductive units on two opposite surfaces of the insulating unit, with the opposite conductive units forming a staggered arrangement.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0023]     Please refer to  FIG. 1  that shows a type of horizontal strip light  10 , said strip light  10  comprising a main unit  12  and a plurality of light-emitting devices  14 .  
         [0024]     The main unit  12  comprises a line-shaped insulating unit  13  and a plurality of strip-shape conductive units  15 ,  16 . Wherein, the strip-shape conductive units  15 ,  16  are parallel to each other and arranged on the same side of the insulating unit  13 . Each of the conductive units  15 ,  16  contain a plurality of pieces, with an interval  18  positioned between two neighboring conductive units  15 , 16  on a same line. Each strip-shape conductive unit  15 , 16  matching the intervals  18  formed on different lines of the conductive units  15 , 16 .  
         [0025]     A plurality of light-emitting devices (such as: LED)  14 , with conductive connecting pins  22 ,  24  respectively connected to the conductive units  15 ,  16  on the main unit  12 .  
         [0026]     The above insulating unit  13  is bent and made into a thin elongated strip. Each light-emitting device  14  has four connecting pins  22 ,  24 . The connecting pins  22 ,  24  of each light-emitting device  14  are respectively connected to the two conductive units  15 ,  16  opposite each other.  
         [0027]     Please refer to  FIGS. 1 and 2 . Since the conductive unit  15  or conductive unit  16  on one side are separated from each other to form an interval, and the conductive unit  16  or conductive unit  15  on the other side is disposed to opposite the two conductive unit  15  or conductive unit  16  that are separated from each other. When a member U 1  of the light-emitting device  14 , and two connecting pins  22  of a member U 2  are connected with the conductive unit  15 , the other two connecting pins  24  are connected with the conductive unit  16 ; then, the two connecting pins  22  of a member U 3  and member U 4  are connected with the conductive unit  16 , and the other two connecting pins  24  are then again connected with the conductive unit  15 ; then, two connecting pins  22  of a member U 5  and member U 6  are then connected with the conductive unit  15 , and the other two connecting pins  24  are then again connected with the conductive unit  16 . In such a status, the member U 1 , member U 2 , member U 3 , member U 4 , member U 5  and member U 6  in the light-emitting device  14  are in parallel connection because their connecting pins  24  are respectively connected to the same conductive unit  15 ,  16 ; meanwhile, the member U 1 , member U 2  and the member U 3 , member U 4 , and the member U 5 , member U 6  are in serial connection.  
         [0028]     According to the above connection, when power source L 1 , L 2  must be respectively connected to the conductive unit  15 ,  16  at the front and rear ends, all light-emitting device  14  and conductive units  15 ,  16  connected in a circuit loop.  
         [0029]     Therefore, even when part of the LED is defective, it will not result in failure of lighting to the entire strip light  10 .  
         [0030]     Importantly, the conductive units  15 ,  16  adopted in the present invention relate to strip-shaped conductive units or other conductive units that are flexible enough to be bent freely and capable of connecting with the connecting pins of the light-emitting device, and in simplified configuration, therefore, during the production process, it can be conveniently fastened to two sides of the insulating unit  13 , in order to satisfy the requirement of mass and rapid production of thin configuration.  
         [0031]     Please refer to  FIG. 3 , since the insulating unit  13  of the main unit  12  has the capability of being bent freely, and all light-emitting devices  14  are striding on the same side of the main unit  12 , the present invention can be bent vertically in application. In its application, the present invention of strip light  10  can be bent and fastened in a corner, such as a corner of house eaves, or a corner on the outside of an advertising signboard. Please refer to  FIG. 4 , the present invention can have a conductive unit  19  on the other side of the insulating unit  13  of the main unit  12 , with the conductive unit  19  connected with the conductive unit  15  or the conductive unit  16 , thereby the power source L 1 , L 2  can be connected to one terminal of the conductive unit  15  or conductive unit  16  not connected to the conductive unit  19 , to constitute a circuit loop. Therefore, in application, the user only needs to cut a required length of strip light, and short-circuit the conductive unit  19  at the bottom and the conductive unit  15  at the top of its terminal, and  15  connect the other terminal to power source L 1 , L 2  to form a circuit loop, without the need of supplying a power source at both terminals.  
         [0032]     Please refer to  FIG. 5 , the present invention can also have a conductive unit  20  between the conductive unit  15  and the conductive unit  16  on the same side of the insulating unit  13  of the main unit  12 , and connect the conductive unit  20  to the conductive unit  15  or conductive unit  16 , thereby the power source L 1 , L 2  can be connected to the conductive unit  15  or conductive unit  16  at one terminal not connected with the conductive unit  20 , forming a circuit loop. Therefore, in application, the user needs to only take a required length of strip light, then short-circuit the conductive unit  20  with the conductive unit  16  at a terminal of the strip light, and connect power source L 1 , L 2  to the other terminal to constitute a circuit, without having to supply a power source at two terminals.  
         [0033]     It is understandable from the above description that the present invention has the structure of a single-unit matrix circuit, which is capable of being bent in application, but will not fail due to damage to part of the light-emitting device  14 , therefore, it has better application performance and the effects of thin shape and lightweight in production.  
         [0034]     Please refer to  FIG. 6  that shows the strip light  10  in a vertical configuration. The strip light  10  include a main unit  12  and a plurality of light-emitting devices  14 .  
         [0035]     The main unit  12  includes an insulating unit  13  and a plurality of strip-shaped conductive units  15 ,  16 . Wherein, the strip-shape conductive units  15 ,  16  are respectively disposed on two sides of an insulating unit  13 . The conductive units  15  or conductive units  16  on the same side are arranged in a line, with an interval  18  disposed between two neighboring conductive units  15  or  16 . Meanwhile, all conductive units  15 ,  16  are disposed to correspond with intervals  18  formed by conductive units  15 , 16  on different lines.  
         [0036]     A plurality of light-emitting devices (such as LED)  14 , their conductive connecting pins  22 ,  24  are respectively connected with conductive units  15 ,  16  of the main unit  12 .  
         [0037]     The insulating unit  13  is bendable and made in the shape of a thin elongated strip. Each light-emitting device  14  has two connecting pins  22 ,  24 ; each of the connecting pins  22 ,  24  of the light-emitting device  14  is respectively connected to the matching two pieces of conductive units  15 ,  16 .  
         [0038]     Please refer to  FIGS. 6 and 7 , since the neighboring conductive units  15  or conductive units  16  on a same side are separated to form intervals, and the opposite conductive units  16  or conductive units  15  are disposed to opposite the two separated conductive units  15  or conductive units  16 . When one connecting pin  22  of the member U 1 , member U 2  of the light-emitting device  14  is connected to the conductive unit  15 , the other connecting pin  24  is connected with the conductive unit  16 ; then, one connecting pin  22  of the member U 3 , member U 4  is connected with the conductive unit  16 , and the other connecting pin  24  is further connected with the conductive unit  15 ; one connecting pin  22  of the member U 5 , member U 6  is further connected with the connector  15 , and the other connecting pin  24  is further connected with the conductive unit  16 ; at this stage  14 , the member U 1 , member U 2 , member U 3 , member U 4 , member U 5  and member U 6  are in parallel connection because their two connecting pins are respectively connected to the same conductive unit  15 , 16 ; meanwhile, the member U 1  and member U 2 , and member U 3  and member U 4 , and member U 5  and member U 6  are connected serially.  
         [0039]     According to the above connection, when power source L 1 ,L 2  must be respectively connected to the conductive unit  15 , 16  at front and rear terminals, all light-emitting member  14  and conductive units  15 , 16  constitute a matrix form of circuit loop. Therefore, even when some part of the LED is defective, it will not result in total failure of the strip light  10 .  
         [0040]     Importantly, the conductive units  15 ,  16  adopted in the present invention relate to strip-shaped conductive units or other conductive units that are flexible enough to be bent freely and capable of connecting with the connecting pins of the light-emitting device, and in simplified configuration, therefore, during the production process, it can be conveniently fastened to two sides of the insulating unit  13 , in order to satisfy the requirement of mass and rapid production of thin configuration.  
         [0041]     Please refer to  FIG. 8 , since the insulating unit  13  of the main unit  12  is capable of being bent freely, and the light-emitting device  14  is capable of striding on two sides of the main unit  12 , in application, it can be bent horizontally. In application, the strip light  10  can be bent and fastened to a corner, such as a corner of a car body, or a corner of a crossroad.  
         [0042]     Please refer to  FIG. 9 , since the insulating unit  13  of the main unit  12  is bendable, and the light-emitting device  14  strides on two sides of the main unit  12 , in application, the user can bend it in a vertical direction. In application, the strip light  10  can be bent and fastened in a corner, such as a corner of a car body or a corner of at a crossroad.  
         [0043]     Please refer to  FIG. 10 , because the main unit is bendable, it is capable of twisting the main unit  12 , thereby, the strip light  10  have the function of displaying in more directions, thereby reducing the intervals of the lights and enabling more variations to the application of the strip light  10 .  
         [0044]     Please refer to  FIGS. 11 and 12 , the present invention can further have a conductive unit  19  inside the insulating unit  13  of the main unit  12 , connecting the conductive unit  19  with the conductive unit  15  or conductive unit  16 , thereby the power source L 1 , L 2  can be connected with the conductive unit  15  or conductive unit  16  at one terminal not connected with the conductive unit  19 , to constitute a circuit loop. In application, it has similar convenience as shown in  FIG. 4  or  5 .  
         [0045]     From the above description and explanation of the application, it is known that the present invention has a single-unit matrix circuit structure, which is bendable in application, so that it can operate even in case of partial damage to the light-emitting device  14 , thereby it has better performance and the effects of thinner and lightweight configuration in production.  
         [0046]     It is to be understood that the above description covering the preferred embodiments of the present prevention and design plans are for reference only, which are not used to limit the scope of the present invention, and that all equivalent skills and approaches without departing from the scope of the present invention shall be included in the subject claim.
