[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1

[0033] like Figure 1-Figure 8 As shown, this embodiment discloses a SMD LED bracket, including a connecting component 2 for placement and mutual splicing, a conductive group 3 for circuit connection is connected to the connecting component 2, wherein the conductive group 3 is divided into a positive pole and a negative pole, a cover component 1 is movably provided on one end of the connecting component 2, a lamp bead 4 is provided between the connecting component 2 and the cover component 1, and the lamp bead 4 is connected to the connecting component 2. When in use, the cover component 1 is used to protect the lamp bead 4, and at the same time, the lamp bead 4 can be mutually connected with the conductive group 3, so that the lamp bead 4 is in a normal use state.

[0034] When connecting the lamp bead 4 to the SMD LED bracket, first bond the lamp bead 4 to the connecting component 2 and ensure that the lamp bead 4 and the conductive group 3 are in an electrically connected state. Then connect the covering component 1 to the connecting component 2 to cover and protect the lamp bead 4 and ensure that the lamp bead 4 is in a normal working state.

[0035] In order to facilitate the carrying and use of the lamp bead 4, the connecting component 2 includes a support base 201, wherein the support base 201 can be used independently when in use, and multiple support bases 201 can also be connected to each other to form a larger module, so that it can meet various lighting needs. A placement cavity 202 is opened on the support base 201, and the lamp bead 4 is located in the placement cavity 202, and the conductive group 3 is connected with the lamp bead 4, that is, the conductive group 3 runs through the support base 201, one end of the conductive group 3 is located in the placement cavity 202, and the other end is located on the outer end surface of the support base 201. After the lamp bead 4 is connected with the conductive group 3 in the placement cavity 202, the other end is connected with the external circuit, so that the lamp bead 4 can emit light normally.

[0036] It should be noted that in the present invention, when the lamp bead 4 is installed and used in the placement cavity 202, according to different use environments, it can be a single light source or a lamp bead 4 realized by combining multiple light sources.

[0037] At the same time, in order to ensure that the lamp bead 4 can meet the lighting needs when in use, and can adjust the lighting intensity and range according to different lighting needs, a plurality of working components 5 are connected in the placement cavity 202, one end of the working component 5 is in contact with the lamp bead 4, and the other end is movably connected to the cavity wall of the placement cavity 202, wherein the connection position between the working component 5 and the lamp bead 4 is close to the connection position between the lamp bead 4 and the support seat 201, that is, the working component 5 blocks the lighting of the lamp bead 4, and a plurality of working components 5 surround the lamp bead 4.

[0038] Furthermore, in order to enable the working component 5 to be used in conjunction with the lamp bead 4 and to identify the usage status of the lamp bead 4 according to the usage status of the working component 5, the working component 5 includes a bending plate 501, which is made of elastic material. The bending plate 501 is connected to one end of the sealing component 1 with a reflective material. Through the cooperation of the bending plate 501, the lamp bead 4 is placed in a trumpet-shaped area. At the same time, because the bending plate 501 is coated with reflective material, when the lamp bead 4 emits light, the reflection of the reflective material on the bending plate 501 can enhance the light intensity of the lamp bead 4. The end of the bending plate 501 away from the sealing component 1 is in contact with an elastic rod 502, wherein the elastic rod 502 is in a bent state, and the bending plate 501 is in contact with the bent portion of the elastic rod 502. When the elastic rod 502 When the angle of the bending part changes, the bending angle of the bending plate 501 will be adjusted accordingly. The two ends of the elastic rod 502 distributed along the length direction are respectively connected to the lamp bead 4 and one end of the placement cavity 202, and the diffusion angle of the lamp bead 4 during irradiation is adjusted by adjusting the bending angle of the bending plate 501 in the placement cavity 202. That is, the bending angle of the bending plate 501 can be adjusted by using the bending condition of the elastic rod 502. When the bending angle of the elastic rod 502 is large, the bending amplitude of the bending plate 501 is also large. When the lamp bead 4 is used for lighting, the light beam will not diverge under the intervention of the bending plate 501. When the bending angle of the elastic rod 502 is small, the bending amplitude of the bending plate 501 becomes smaller, and the light beam diverges under the intervention of the bending plate 501.

[0039] Furthermore, in order to ensure that the cover assembly 1 can cover the lamp bead 4 without interfering with the use of the lamp bead 4, the cover assembly 1 includes a cover plate 101, which can be snap-fitted with the support seat 201. In the present invention, the cross-sectional shape of the cover plate 101 is a "door" shape, and notches are provided on both sides of the support seat 201 for cooperating with the cover plate 101, so that when the cover assembly 1 is connected to the support seat 201, the cover plate 101 can be snap-fitted with the support seat 201, thereby ensuring the stability of the cover assembly 1 and the connecting assembly 2 when connected. A transparent plate 102 is connected to the cover plate 101, and the transparent plate 102 can cover the lamp bead 4 without contacting the lamp bead 4. When the lamp bead 4 is working, the light beam generated by the lamp bead 4 can pass through the transparent plate 102 to reach the outside world.

[0040] Furthermore, since the long-term use of the lamp bead 4 will generate a lot of heat, the connection state between the lamp bead 4 and the conductive group 3 will become unstable, and the service life and luminous efficiency of the lamp bead 4 will be reduced. When in use, the working space of the lamp bead 4 needs to be cooled. The connecting component 2 also includes a temperature control cavity 203, wherein the temperature control cavity 203 is not connected to the placement cavity 202, and the extension end of the elastic rod 502 is located in the temperature control cavity 203. The elastic rod 502 is slidably connected on the cavity wall between the temperature control cavity 203 and the placement cavity 202, and the temperature control cavity 203 is connected with a The control component 6 is used to adjust the bending degree of the elastic rod 502. The control component 6 is connected to the elastic rod 502. When in use, the bending degree of the elastic rod 502 is adjusted by the contact between the control component 6 and the elastic rod 502, so as to control the bending angle of the bending plate 501. At the same time, the elastic rod 502 is set to transport the heat generated by the placement cavity 202 and the lamp bead 4. The elastic rod 502 is used as a transmission medium to allow the heat in the placement cavity 202 to enter the temperature control cavity 203, thereby achieving temperature balance in the placement cavity 202.

[0041] Furthermore, in order to ensure that the control assembly 6 can effectively control the bending plate 501 when in use, the control assembly 6 includes a deflection plate 601, one end of which is rotatably connected to the cavity wall of the temperature control cavity 203, and a torsion spring is provided at the rotation point of the deflection plate 601 and the temperature control cavity 203, thereby ensuring that the rotation angle of the deflection plate 601 is constant, ensuring that when the bending degree of the elastic rod 502 does not change, the deflection angle of the deflection plate 601 can support the elastic rod 502, and the elastic rod 502 is not changed. 02 The end away from the lamp bead 4 contacts the deflection plate 601, and the end of the deflection plate 601 away from the temperature control chamber 203 is connected with a connecting rope 602. When the angle of the deflection plate 601 changes, the connecting rope 602 will also move with the deflection plate 601. It should be noted that when the bending angle of the elastic rod 502 changes, the length of the elastic rod 502 will also increase, and the resistance force of the elastic rod 502 to the deflection plate 601 will increase, which can drive the deflection plate 601 to rotate.

[0042] Furthermore, in order to improve the thermal conductivity of the elastic rod 502 and reduce the interference of temperature on the lamp bead 4, a thermal conductive core 5021 is penetrated through the elastic rod 502, wherein the thermal conductivity of the thermal conductive core 5021 is greater than the thermal conductivity of the elastic rod 502. It should be noted that the elastic rod 502 is made of elastic material, and the elastic modulus of the elastic material decreases as the temperature rises, and the length of the elastic rod 502 will extend, so that the elastic rod 502 and the thermal conductive core 5021 can control the deflection angle of the deflection plate 601 while converting the temperature.

[0043] Furthermore, the cover assembly 1 also includes an air hole 1011, which can connect the placement cavity 202 with the outside world, ensuring that the heat in the placement cavity 202 can be exchanged with the outside world through the air hole 1011, thereby improving the heat dissipation efficiency of the SMD LED bracket. The end of the connecting rope 602 away from the deflection plate 601 is located in the air hole 1011, and the air hole 1011 is in the shape of a three-way hole. The end of the connecting rope 602 away from the deflection plate 601 is connected to a block 1012, and the block 1012 can block the air hole 1011. When the angle of the deflection plate 601 changes and drives the connecting rope 602 to move, it can drive the block 1012 to move in the air hole 1011, so that the air hole 1011 connects the placement cavity 202 with the outside world, thereby improving the heat dissipation efficiency.

[0044] Furthermore, an insulating layer 7 is provided at one end of the lamp bead 4 away from the cover assembly 1, and the insulating layer 7 is located on the connecting assembly 2, ensuring that the lamp bead 4 will not be short-circuited when in use, thereby improving the use efficiency of the lamp bead 4 and reducing the failure rate.

[0045] When in use, first connect the lamp bead 4 to the placement cavity 202, and at the same time ensure that the lamp bead 4 is connected to the conductive group 3 to ensure the normal use of the lamp bead 4, then snap the cover assembly 1 and the connecting assembly 2 together. During the snap-on process, connect the connecting rope 602 to ensure the normal operation of the control assembly 6.

[0046] Before the lamp bead 4 is used, the bending plate 501 is at the maximum deflection angle, and the positions of the elastic rod 502 and the deflection plate 601 are adapted to the angle of the bending plate 501 , and the stopper 1012 blocks the air hole 1011 .

[0047] As the use time of the lamp bead 4 increases, the temperature of the lamp bead 4 and the placement cavity 202 increases and becomes greater than the temperature in the temperature control cavity 203. The heat conductive core 5021 arranged in the elastic rod 502 introduces the heat from the placement cavity 202 and the lamp bead 4 into the temperature control cavity 203, thereby reducing the rate of increase of the temperature in the lamp bead 4 and the placement cavity 202, ensuring the stability of the working temperature of the lamp bead 4 and increasing the service life of the lamp bead 4. At the same time, because the angle of the elastic rod 502 has not changed, the reflective material on the surface of the bending plate 501 can reflect and reinforce the light of the lamp bead 4, thereby improving the use experience of the lamp bead 4.

[0048] When the heat conduction rate of the heat conductive core 5021 is lower than the heat generation efficiency of the lamp bead 4, the elastic rod 502 is affected by the temperature in the placement chamber 202, and the elastic strength of the elastic rod 502 decreases, resulting in a decrease in the supporting strength of the bending plate 501. Under the elastic pressure of the bending plate 501, the elastic rod 502 and the cavity wall of the placement chamber 202 are prompted to slide relative to each other, resulting in the length of the elastic rod 502 in the temperature control chamber 203 being extended, causing the elastic rod 502 and the deflection plate 601 to slide relative to each other, and driving the deflection plate 601 and the cavity wall of the temperature control chamber 203 to rotate relative to each other, driving the connecting rope 602 to slide, ensuring relative movement between the block 1012 and the air vent 1011, so that the air vent 1011 connects the placement chamber 202 with the outside world to achieve gas exchange, thereby achieving the purpose of heat dissipation of the placement chamber 202.

[0049] At the same time, the distance that the block 1012 moves in the air hole 1011 is related to the deflection angle of the deflection plate 601, that is, after the deflection plate 601 is deflected by a certain angle, the block 1012 is in a semi-closed state with respect to the air hole 1011, so that the air hole 1011 first exchanges gas with the placement chamber 202. During this process, if the temperature in the placement chamber 202 continues to rise, the bending plate 501 will be prompted to further compress the elastic rod 502, so that the block 1012 completely opens the air hole 1011.

[0050] It should be noted that an elastic reset component, preferably a reset spring, is provided between the stopper 1012 and the hole wall of the air vent 1011 , and the reset spring will not interfere with the process of the deflection plate 601 driving the stopper 1012 to move.

[0051] At the same time, as the deflection angle of the bending plate 501 decreases, the number of reflections of the light beam generated by the lamp bead 4 on the bending plate 501 will decrease. At the same time, the spatial range formed by the bending plate 501 will increase, which will reduce the convergence rate of the heat generated by the lamp bead 4, thereby achieving the purpose of cooling the placement cavity 202 and ensuring that the use of the lamp bead 4 is not interfered with.

[0052] When the temperature in the placement chamber 202 drops, the temperature of the elastic rod 502 will drop, thereby restoring the elastic strength of the elastic rod 502 and shortening the length of the elastic rod 502 in the temperature control chamber 203, driving the bending angle of the bending plate 501 to increase, and prompting the block 1012 to re-close the air vent 1011 to maintain normal lighting of the lamp bead 4.

[0053] Embodiment 2:

When the LED lamp bead is in use, the light color of the lamp bead 4 is adjusted by using the LED chip. At the same time, according to different use environments, the light intensity of the lamp bead 4 is controlled by controlling the LED chip, thereby improving the use scenarios of the LED lamp bead.
