[0034] First Embodiment
[0035] Figure 1 is a top view schematic diagram of the carrying bracket according to the embodiment of the present utility model. As Figure 1 shown, the present utility model provides a carrying bracket 1, including a first bracket group 11, a second bracket group 12 and a plurality of pins 13.
[0036] The first bracket group 11 has a first surface and a second surface opposite to the first surface. A first mounting area 110 is provided on the first surface. The shape of the first mounting area 110 is a polygon, such as a quasi-rectangle, and the first mounting area 110 has a first major axis A1 extending along the first direction D1. In this embodiment, the first bracket group 11 is made of a metal material. From a top view, the second bracket group 12 is a strip-shaped member disposed above the first bracket group 11. The second bracket group 12 has a third surface and a fourth surface opposite to the third surface. A second mounting area 120 is provided on the third surface. The shape of the second mounting area 120 is a polygon, such as a quasi-rectangle. In this embodiment, the second bracket group 12 can also be made of a metal material, and the second mounting area 120 has a second major axis A2 extending along the second direction D2, where the second direction D2 is different from the first direction D1. For example, there is an angle greater than zero between the second direction D2 and the first direction D1. In this embodiment, the second direction D2 and the first direction D1 are perpendicular to each other, but the present invention is not limited thereto. There is a first gap G1 between the first bracket group 11 and the second bracket group 12, that is to say, the first mounting area 110 and the second mounting area 120 are also separated. Among them, a plurality of pins 13 are located on two opposite sides of the first bracket group 11, and the pins 13 provided on each side are arranged at intervals along the first direction D1, and there is a second gap G2 between the plurality of pins 13 and the first bracket group 11.
[0037] Specifically, the first bracket group 11 further includes a first extension portion 111 connected to one side of the first mounting area 110. The first bracket group 11 further includes a second extension portion 112 connected to the other side of the first mounting area 110 (the side where the first extension portion 111 is not provided). From a top view, the second extension portion 112 extends outward along the first direction D1 from below the first mounting area 110.
[0038] As Figure 1 shown, the first bracket group can be a T-shaped bracket group. That is to say, the first extension portion 111 extends along the second direction D2 to both sides and forms a T shape with the first major axis A1, but it is not limited thereto.
[0039] In addition, the second bracket group 12 further includes at least one third extension portion 121 connected to one side of the second mounting area 120. From a top view, the third extension portion 121 extends outward along the first direction D1 from above the second mounting area 120. In this embodiment, the number of the third extension portions 121 is multiple, such as three, but it is not limited thereto. The second bracket group 12 further includes a fourth extension portion 122 that extends outward along the second direction D2 from the opposite sides of the second mounting area 120 (where the third extension portions 121 are not provided).
[0040] Each pin 13 has a fifth surface and a sixth surface opposite to the fifth surface. The fifth surface is provided with an electrical contact area 130 and a fifth extension 131 extending away from the first mounting area 110 along a second direction D2 from one side of the electrical contact area 130, and the fifth extension 131 has a predetermined width narrower than any side length of the corresponding electrical contact area 130. In the carrier bracket 1 of this embodiment, a plurality of pins 13 are arranged on the left and right sides of the first mounting area 110, at least two pins 13 are provided on each side, and among the at least two pins 13 provided on each side, the pin 13 adjacent to the second extension 112 further includes a sixth extension 132 extending outward along a first direction D1.
[0041] Figure 4 It is a schematic diagram of the carrier bracket array structure of the present utility model. As Figure 4 shown, in the forming process, when a plurality of carrier brackets 1 are in an array arrangement structure, two adjacent carrier brackets 1 are connected into one body through the first extension 111, the second extension 112, the third extension 121, the fourth extension 122, the fifth extension 131 and the sixth extension 132, so as to prevent the first bracket group 11 and the second bracket group 12 from being a floating island without a support element.
[0042] The first extension 111 and the second extension 112 extend outward relative to the first mounting area 110 to form a narrow cross-sectional area structure, that is to say, the first extension 111 and the second extension 112 have a predetermined width shorter than any side length of the first mounting area 110. Similarly, the third extension 121 and the fourth extension 122 also extend outward relative to the second mounting area 120 to form a narrow cross-sectional area structure, that is to say, the third extension 121 and the fourth extension 122 have a predetermined width shorter than any side length of the second mounting area 120. A narrow cross-sectional area structure formed by the first extension 111, the second extension 112, the third extension 121 and the fourth extension 122 is located around the carrier bracket 1. In the forming process, these narrow cross-sectional area structures can prevent the problem of material chipping during the cutting of the carrier bracket 1, and the cutting area of the narrow cross-sectional area structure is small, which can reduce the wear of the tool and is not easy to produce the problem of burrs on the cutting edge.
[0043] In addition, in another embodiment, the surfaces of the first mounting area 110 and the second mounting area 120 may be higher than the surfaces of the first extension 111, the second extension 112, the third extension 121, and the fourth extension 122. In other words, the first bracket group 11 and the second bracket group 12 form an annular concave structure around the first mounting area 110 and the second mounting area 120, resulting in the first mounting area 110 and the second mounting area 120 being protrusion structures similar to islands. Similarly, an annular concave structure may also be formed around the electrical contact area 130 of the pin 13, resulting in the electrical contact area 130 being a protrusion structure similar to an island. In short, in this embodiment, the thickness of the first bracket group 11, the second bracket group 12, and the pin 13 near the edge may be less than or equal to the predetermined thickness of the first bracket group 11, the second bracket group 12, and the pin 13.
[0044] Figure 2 is a top view schematic diagram of the light-emitting device according to an embodiment of the present invention. As Figure 2 shown, a light-emitting device LE includes a carrier bracket 1, a housing 2, a driving element 3, and at least one light-emitting element 4. The driving element 3 is disposed in the first mounting area 110 of the first bracket group 11 of the carrier bracket 1 and is electrically connected to a plurality of pins 13. In this embodiment, the driving element 3 is electrically connected to the corresponding plurality of pins 13 through a plurality of wires, such as metal wires. The first bracket group is a T-shaped bracket group (as Figure 1 shown). Among them, the plane formed by the three endpoints of the T character can provide a stable installation of the driving element 3 on the first mounting area 110, but it is not limited thereto. At least one light-emitting element 4 is disposed in the second mounting area 120 and is electrically connected to the driving element 3. In this embodiment, at least one light-emitting element 4 is electrically connected to the driving element 3 through at least one wire, such as a metal wire.
[0045] The housing 2 is made by a molding process and has an appearance of a cup-shaped structure with an opening, and the cup wall surrounds the carrier bracket 1. That is to say, the height around the housing 2 is higher than the surface of the carrier bracket 1. Therefore, the housing 2 arranged around the carrier bracket 1 defines a receiving space 21 with an opening O. And the housing 2 covers the periphery of the carrier bracket 1 and also covers part of the bottom end 216 of the receiving space 21, so that at least a part of the first bracket group 11, the second bracket group 12, and the plurality of pins 13 are exposed at the bottom end 216. In other words, the housing 2 covers part of the first bracket group 11, the second bracket group 12, and the plurality of pins 13, fills the first gap G1 and the second gap G2, and exposes part of the first mounting area 110, the second mounting area 120, and the electrical contact area 130 of the plurality of the pins 13. Since the narrow cross-sectional area structures formed by the first extension portion 111, the second extension portion 112, the third extension portion 121, and the fourth extension portion 122 are located around the carrier bracket 1, after the housing 2 is molded and forms a single package, these narrow cross-sectional area structures reduce the area of the carrier bracket 1 exposed to the outside, and can reduce the intrusion of moisture.
[0046] In another embodiment, the housing 2 covers part of the first bracket group 11, the second bracket group 12, and the plurality of pins 13. In addition to filling the first gap G1 and the second gap G2, it also fills the annular recessed structure and exposes part of the first mounting area 110, the second mounting area 120, and the electrical contact area 130 of the plurality of the pins 13. In addition to improving the bonding force between the housing 2 and the carrier bracket 1, it can also reduce the intrusion of moisture.
[0047] The housing 2 includes a partition 22, which is located in the receiving space 21 and isolates the first bracket group 11, the second bracket group 12, and the pins 13. In other words, the partition 22 divides the receiving space 21 into a plurality of sub-spaces, and the driving element 3, at least one light-emitting element 4, and the plurality of pins 13 are respectively arranged in different sub-spaces. Among them, the plurality of sub-spaces include a first sub-space 211, a second sub-space 212, and two third sub-spaces 213. The driving element 3 is arranged in the first sub-space 211, at least one light-emitting element 4 is arranged in the second sub-space 212, and at least two pins 13 are arranged in each third sub-space 213. Since the driving element 3 and the light-emitting element 4 are respectively arranged in independent sub-spaces 211, 212, the driving element 3 is not easily affected by crosstalk. In addition, the housing 2 is made of a material with a high reflectivity, which can provide a complete reflection path and sufficient reflection intensity for the light-emitting element 4 arranged in the independent sub-space. Therefore, the brightness of the light-emitting element 4 can be further improved. In a preferred embodiment, the reflectivity of the housing 2 to the light beam emitted by the light-emitting element 4 is not less than 80%.
[0048] Further illustrate the distribution positions of the respective sub-spaces of the partition portion 22. The housing 2 has a first inner side surface 23 and a second inner side surface 24 that are opposite in the first direction D1, and a third inner side surface 25 and a fourth inner side surface 26 that are opposite in the second direction D2. The partition portion 22 includes a first retaining wall 221, a second retaining wall 222, and a third retaining wall 223. Among them, the first retaining wall 221 extends along the second direction D2, the first end of the first retaining wall 221 is connected to the first inner side surface 23, and the second end of the first retaining wall 221 is connected to the second inner side surface 24. The second retaining wall 222 branches from a position adjacent to the first end of the first retaining wall 221 and extends in the first direction D1, and is connected between the first retaining wall 221 and the fourth inner side surface 26. The third retaining wall 223 branches from a position adjacent to the second end of the first retaining wall 221 and extends in the first direction D1, and is connected between the first retaining wall 221 and the fourth inner side surface 26. The plurality of sub-spaces are formed by the plurality of inner side surfaces. Among them, the first retaining wall 221, the second retaining wall 222, the third retaining wall 223, and the fourth inner side surface 26 define a first sub-space 211; the first retaining wall 221, the first inner side surface 23, the second inner side surface 24, and the third inner side surface 25 define a second sub-space 212; the first retaining wall 221, the second retaining wall 222, the first inner side surface 23, the fourth inner side surface 26, and the first retaining wall 221, the third retaining wall 223, the second inner side surface 24, the fourth inner side surface 26 respectively define a third sub-space 213. The lengths of the plurality of retaining walls are such that the length of the first retaining wall 221 in the second direction D2 is greater than or equal to the length of the second retaining wall 222 or the third retaining wall 223 in the first direction D1. And the height of the plurality of retaining walls can prevent the die bonding glue from overflowing into the wire bonding area. In addition, since the pins 13 are separated by the partition portion 22 in the accommodating space 21, that is, the third sub-spaces 213 located on the opposite sides of the first sub-space 211, the independent setting of the pins 13 can simplify the wire bonding complexity of the light-emitting device LE.
[0049] Figure 3 is a top view schematic diagram of the light-emitting device according to the second embodiment of the present invention. As Figure 3As shown, the partition portion 22 further includes a first recess 224 and a second recess 225. Among them, the second retaining wall 222 is provided with a first recess 224 at the connection with the first retaining wall 221, and the third retaining wall 223 is provided with a second recess 225 at the connection with the first retaining wall 221. Compared with the first sub-space 211 without the first recess 224 and the second recess 225, the first recess 224 and the second recess 225 can be used to increase the first sub-space 211, so that the first bracket group 11 located in the first sub-space 211 has a first wire bonding area 214 and a second wire bonding area 215 corresponding to the first recess 224 and the second recess 225 respectively. The increased wire bonding areas can make the light-emitting device LE applicable to different types of driving elements 3. In addition, the first mounting area 110 can provide a large heat dissipation area in complete contact with the driving element 3, so it is possible to avoid the output current attenuation caused by the too high operating temperature range of the driving element 3, thereby reducing the brightness of the light-emitting element 4.
[0050] Figure 5 It is a schematic diagram of the pin signal positions of the driving element in the first embodiment of the present invention. The multiple pins 13 of the carrier bracket 1 arrange the pins 13 at different positions according to the signals of the first driving chip or the second driving chip as the power supply terminal VDD, the ground terminal GND, and the input / output terminal I / O of the driving element 3. In this embodiment, the input / output terminal I / O includes signal terminals such as a data signal input terminal (DAI), a clock signal input terminal (CKI), a data signal output terminal (DAO), and a clock signal output terminal (CKO). As Figure 5 shown, the driving element 3 in the first embodiment is a first driving chip 31, and the first driving chip 31 has a plurality of first electrical contacts 310. The plurality of first electrical contacts 310 are electrically connected to the plurality of pins 13 and at least one light-emitting element 4 through a plurality of first wires 311 respectively. In this embodiment, the number of at least one light-emitting element 4 is multiple, and the multiple light-emitting elements 4 may have the same or different wavelengths, such as red light-emitting elements, blue light-emitting elements, green light-emitting elements, but not limited thereto. In this embodiment, the driving element 3 is electrically connected to each monochromatic light-emitting element 4 by different first wires 311 respectively. Therefore, when the light-emitting device LE shows an abnormality, the actual current values of each color light-emitting element can be independently tested, and through cyclic redundancy check (CRC), the light-emitting element 4 showing the abnormality can be found. The present invention can select a suitable verification method, not limited to the examples given above.
[0051] Second Embodiment
[0052] Figure 6Schematic diagram of the pin signal positions of the driving element according to the second embodiment of the present utility model. Multiple pins 13 of the carrier bracket 1 arrange pins 13 at different positions according to the signals of the first driving chip or the second driving chip as the power supply terminal VDD, the ground terminal GND, and the input / output terminal I / O of the driving element 3. In this embodiment, the input / output terminal I / O includes signal terminals such as a data signal input terminal (DAI), a clock signal input terminal (CKI), a data signal output terminal (DAO), and a clock signal output terminal (CKO). As Figure 6 shown, the driving element 3 of the second embodiment is the second driving chip 32. The second driving chip 32 has multiple second electrical contacts 320, and the number of the multiple second electrical contacts 320 is greater than the number of the multiple first electrical contacts 310. Specifically, the multiple second electrical contacts 320 are respectively electrically connected to the multiple pins 13, at least one light-emitting element 4, the first wire bonding area 214, and the second wire bonding area 215 through multiple second wires 321. Since a pair of wire bonding areas 214 and 215 are provided in the first installation area 110 in this embodiment, the light-emitting device LE can be used for high-order driving chips with a large number of electrical contacts or low-order driving chips with a small number of electrical contacts. The increased wire bonding areas 214 and 215 increase the elastic selection of the driving element 3 and improve the application range of the driving element 3. In this embodiment, preferably, the two wire bonding areas 214 and 215 can be symmetrically arranged. In addition, since the light-emitting device LE of this embodiment can be installed with a high-order driving chip, the light-emitting device LE has the functions of detecting the operating temperature of the driving element 3 and regulating abnormal temperature.

[0054] One of the beneficial effects of the present utility model is that the carrier bracket, the light-emitting device, and the light-emitting device array provided by the present utility model can, through the technical solutions of "providing a carrier bracket 1, the carrier bracket 1 having a first bracket group 11, a second bracket group 12, and multiple pins 13, the surface of the first bracket group 11 having a first installation area 110, and the surface of the second bracket group 12 having a second installation area 120", "the driving element 3 is arranged in the first installation area 110, the light-emitting element 4 is arranged in the second installation area 120, and is electrically connected to the driving element", and "a housing 2, which is arranged around the carrier bracket 1 to define an accommodating space 21 with an opening, and the housing 2 covers at least a part of the bottom end of the accommodating space 21, and at least a part of the first bracket group 11, the second bracket group 12, and the multiple pins 13 are exposed at the bottom end", make the driving element and the light-emitting element be independently arranged in different areas to improve the display brightness of the light-emitting device.
[0055] Furthermore, the first bracket group 11 is a T-shaped bracket group. The plane formed by the three endpoints of the T shape can stably provide the driving element 3 to be mounted on the first mounting area 110. Thereby, the first mounting area 110 can provide a large heat dissipation area in complete contact with the driving element 3. Therefore, it can be avoided that the output current decays due to the over-high operating temperature range of the driving element 3, and the brightness of the light-emitting element 4 is reduced.
[0056] In addition, a narrow cross-sectional area structure is formed by the first extension portion 111, the second extension portion 112, the third extension portion 121, and the fourth extension portion 122 around the carrier bracket 1. In the forming process, these narrow cross-sectional area structures can avoid the problem of material chipping during the cutting of the carrier bracket 1. Moreover, the cutting area of the narrow cross-sectional area structure is small, which can reduce the wear of the cutting tool and is not prone to the problem of burrs on the cutting edge. The narrow cross-sectional area structure reduces the area of the carrier bracket 1 exposed on all sides, and can reduce the intrusion of moisture.
[0057] In addition, the driving element 3 of the present utility model is connected to each monochromatic light-emitting element 4 by a single wire. When the lighting device LE shows an abnormality, the actual current value of each color light-emitting element can be independently tested, and through cyclic redundancy check, the light-emitting element showing the abnormality can be found.

Therefore, all equivalent technical changes made by using the content of the specification and drawings of the present utility model are included in the protection scope of the claims of the present utility model.
