[0002] With the development of the film and television industry, film and television lights are increasingly appearing in usage scenarios with harsh environmental conditions, thus requiring higher and higher IP protection levels for film and television lights.
[0003] In related technologies, film and television lights typically have two independent sealed cavities, each used to seal the light source assembly and the driver board. This results in a large number of sealing structures in the film and television light. Furthermore, the light source assembly and the driver board need to be connected by wires, which requires the sealed cavities to have sealed connectors through which the power supply wires pass. This excessive number of sealing structures increases the overall material and assembly costs of the film and television light. In addition, too many sealing structures can also lead to the failure of the film and television light after long-term use. Utility Model Content

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0024] Please refer to the following: Figures 1-2 This application proposes a film and television light 100. In the embodiments of this application, the film and television light 100 includes a housing assembly 10, a heat dissipation assembly 20, a light source assembly 30, a driver board 40, and a control board 50.
[0025] The housing assembly 10 is used to house various components of the video lamp 100. The housing assembly 10 can be made of metal or plastic, and this embodiment does not limit this. When the housing assembly 10 is made of metal, it has advantages such as better strength. The housing assembly 10 has a first mounting cavity 10A, a second mounting cavity 10B, and a third mounting cavity 10C formed inside.
[0026] The heat dissipation component 20 is used to dissipate the heat generated during the operation of the light source component 30, the driver board 40, and the control board 50. The heat dissipation component 20 can be in the form of heat sink fins and heat pipes to quickly dissipate heat to the outside of the video light 100. The heat dissipation component 20 is disposed within the first mounting cavity 10A.
[0027] The light source assembly 30 is used to emit light. The light source assembly 30 may include a COB light source and a mixing cup. The light emitted by the COB light source is mixed by the mixing cup before being emitted to the outside, which makes the light emitted by the film and television light 100 more uniform in color. This embodiment does not limit the specific form of the light source assembly 30. The light source assembly 30 is disposed in the second mounting cavity 10B.
[0028] The driver board 40 is equipped with a driving circuit, which generates and outputs a dimming signal for driving the light source assembly 30. The driver board 40 is disposed in the second mounting cavity 10B and is electrically connected to the light source assembly 30. For example, the driver board 40 can be electrically connected to the COB light source of the light source assembly 30 via a wire.
[0029] The control board 50 plays a central control role. The control board 50 is located in the third mounting cavity 10C and is electrically connected to the drive board 40. It can be understood that the control board 50 can be electrically connected to the drive board 40 via wires.
[0030] The second mounting cavity 10B, the first mounting cavity 10A, and the third mounting cavity 10C are independent of each other, and the second mounting cavity 10B and the third mounting cavity 10C are respectively sealed. In this embodiment, liquids, dust, and other impurities can only flow into the first mounting cavity 10A. The sealing of the second mounting cavity 10B and the third mounting cavity 10C prevents liquids, dust, and other impurities from flowing into the second mounting cavity 10B and the third mounting cavity 10C from the outside or the first mounting cavity 10A. This ensures that the light source assembly 30, the driver board 40, and the control board 50 are not affected by liquids, dust, and other impurities, thereby effectively improving the waterproof and dustproof performance of the film and television light 100 to achieve a higher IP rating.
[0031] In this embodiment, the light source assembly 30 and the driver board 40 are housed within a sealed second mounting cavity 10B. On the one hand, this embodiment only requires sealing the second sealing cavity to achieve the joint sealing of the light source assembly 30 and the driver board 40. On the other hand, the light source assembly 30 and the driver board 40 can be electrically connected within the second mounting cavity 10B via wires, eliminating the need for sealing the wires. Thus, the technical solution of this embodiment simplifies the overall sealing structure of the film and television light 100, reducing the number of sealing structures and effectively lowering the overall material and assembly costs of the film and television light 100.
[0032] Please refer to the following: Figures 1-2 In some embodiments, the second mounting cavity 10B, the first mounting cavity 10A, and the third mounting cavity 10C are arranged sequentially along the front-to-back direction of the video lamp 100. In this way, the heat from the second mounting cavity 10B and the third mounting cavity 10C can be conducted to the heat dissipation assembly 20 located in the first mounting cavity 10A, thereby enabling the heat dissipation assembly 20 to quickly dissipate the heat from the light source assembly 30, the driver board 40, and the control board 50.
[0033] Please refer to the following: Figures 1-3 as well as Figures 6-7In some embodiments, the housing assembly 10 includes a first mounting housing 11 and a second mounting housing 12, which are separately disposed, wherein the second mounting cavity 10B constitutes a portion of the first mounting cavity 10A.
[0034] The first mounting shell 11 is connected to the second mounting shell 12, and the two cooperate to form the second mounting cavity 10B. The video lamp 100 also includes a first sealing ring 80, which is disposed between the first mounting shell 11 and the second mounting shell 12 to make the second mounting cavity 10B sealed.
[0035] In this way, the excellent dynamic sealing capability of the first sealing ring 80 can be utilized to seal the gap between the first mounting shell 11 and the second mounting shell 12, thereby effectively preventing impurities such as liquid and dust from entering the second mounting cavity 10B. This design makes the sealing performance of the second mounting cavity 10B better.
[0036] In other embodiments, the second mounting cavity 10B can also be sealed by filling the gap between the first mounting housing 11 and the second mounting housing 12 with sealant.
[0037] Optionally, the second mounting shell 12 has a first sealing groove 121 formed on the side facing the first mounting shell 11, and a first sealing ring 80 is disposed in the first sealing groove 121. The first mounting shell 11 has a first rib 111 protruding on the side facing the second mounting shell 12.
[0038] The first rib 111 is inserted into the first sealing groove 121 and presses against the first sealing ring 80, so that the first sealing ring 80 is located between the first mounting shell 11 and the second mounting shell 12.
[0039] In this way, the first sealing ring 80 can be fixed in the first sealing groove 121 by the cooperation and pressure between the first rib 111 and the groove wall of the first sealing groove 121, thereby preventing liquid, dust and other impurities from flowing into the second mounting cavity 10B from the gap between the first mounting shell 11 and the second mounting shell 12.
[0040] Of course, this application is not limited to this. It can also be replaced by the second mounting shell 12 being provided with a first rib 111 and the first mounting shell 11 being formed with a first sealing groove 121, so that the first sealing ring 80 is fixed in the first sealing groove 121 by inserting the first rib 111 into the first sealing groove 121.
[0041] Please refer to the following: Figures 1-2 , Figure 4 , Figure 6 as well as Figure 8In some embodiments, a light outlet 112 is formed on the side of the first mounting housing 11 away from the second mounting housing 12. It is understood that the light emitted by the light source assembly 30 can be emitted outward through the light outlet 112.
[0042] The light outlet 112 has a recessed wall forming a second sealing groove 1121. The video lamp 100 also includes a second sealing ring 81, which is inserted into the second sealing groove 1121. The housing assembly 10 includes a lamp body front shell 13, which is connected to the first mounting shell 11 and presses against the second sealing ring 81, so that the second sealing ring 81 is located between the lamp body front shell 13 and the first mounting shell 11.
[0043] In this way, the excellent dynamic sealing capability of the second sealing ring 81 can be utilized to seal the gap between the lamp body front shell 13 and the first mounting shell 11, thereby effectively preventing impurities such as liquid and dust from entering the second mounting cavity 10B through the light outlet 112, resulting in better sealing performance.
[0044] Furthermore, in order to improve the light mixing effect of the light emitted from the light source component 30, the film and television light 100 also includes an optical lens 70. For example, the optical lens 70 can be a light mixing glass. It is understood that the light emitted from the COB light source will first pass through the light mixing cup and then be directed to the light mixing glass to further improve the uniformity of light mixing.
[0045] The second sealing ring 81 has a third sealing groove 811 formed on its side wall. The optical lens 70 is inserted into the third sealing groove 811. The lamp body front shell 13 presses against the second sealing ring 81 so that the groove wall of the third sealing groove 811 is in close contact with the optical lens 70. In this way, the uniformity of light mixing of the video lamp 100 can be improved, while preventing liquids, dust and other impurities from flowing into the second mounting cavity 10B from the gap between the lamp body front shell 13 and the optical lens 70.
[0046] Please refer to the following: Figures 1-2 , Figures 5-6 as well as Figure 9 In some embodiments, the housing assembly 10 includes a lamp body rear housing 14 and a third mounting housing 15. The third mounting housing 15 forms a portion of the first mounting cavity 10A. The lamp body rear housing 14 is connected to the third mounting housing 15 to cooperate in forming the third mounting cavity 10C.
[0047] The film and television light 100 also includes a third sealing ring 84, which is located between the rear shell 14 of the light body and the third mounting shell 15, so that the third mounting cavity 10C is sealed.
[0048] In this way, the excellent dynamic sealing capability of the second sealing ring 81 can be used to seal the gap between the lamp body rear shell 14 and the third mounting shell 15, thereby effectively preventing impurities such as liquid and dust from entering the third mounting cavity 10C and affecting the control board 50. This arrangement makes the sealing performance of the third mounting cavity 10C better.
[0049] Optionally, a fourth sealing groove 151 is formed on the side of the third mounting shell 15 facing the rear shell 14 of the lamp body, and a third sealing ring 84 is disposed in the fourth sealing groove 151. A second rib 141 protrudes from the side of the rear shell 14 of the lamp body facing the third mounting shell 15.
[0050] The second rib 141 is inserted into the fourth sealing groove 151 and presses against the third sealing ring 84, so that the third sealing ring 84 is located between the lamp body rear shell 14 and the third mounting shell 15.
[0051] In this way, the third sealing ring 84 can be fixed in the fourth sealing groove 151 by the cooperation and pressure between the second rib 141 and the groove wall of the fourth sealing groove 151. Thus, the third sealing ring 84 can prevent liquids, dust and other impurities from flowing into the third mounting cavity 10C from the gap between the lamp body rear shell 14 and the third mounting shell 15.
[0052] Of course, this application is not limited to this. It can also be replaced by providing a second rib 141 on the rear shell 14 of the lamp body and forming a fourth sealing groove 151 on the third mounting shell 15, so that the third sealing ring 84 is fixed in the fourth sealing groove 151 by inserting the second rib 141 into the fourth sealing groove 151.
[0053] Please refer to the following: Figures 1-2 In some embodiments, the video light 100 also includes a power supply unit 60, which is electrically connected to the control board 50. In this way, the power supply unit 60 can provide power to the control board 50, thereby providing the required power to electrical components such as the light source assembly 30.
[0054] The power supply component 60 is housed within the third mounting cavity 10C. This sealed arrangement of the third mounting cavity 10C prevents the power supply component 60 from being affected by water, dust, or other impurities. Furthermore, by housing the control board 50 and the power supply component 60 within the third mounting cavity 10C, both components are sealed together. Additionally, the power supply component 60 and the control board 50 can be electrically connected within the third mounting cavity 10C via wires, eliminating the need for sealing the wires. Thus, the technical solution of this embodiment simplifies the overall sealing structure of the video light 100, reducing the number of sealing structures and effectively lowering the overall material and assembly costs of the video light 100.
[0055] Please refer to the following: Figure 2 as well as Figures 6-9 In some embodiments, the first mounting shell 11 is provided with a first wire passage 113 communicating with the second mounting cavity 10B, and the third mounting shell 15 is provided with a second wire passage 152 communicating with the third mounting cavity 10C. It can be understood that the control board 50 and the drive board 40 are electrically connected by wires. Therefore, the wires need to be connected to the control board 50 and the drive board 40, and thus the wires need to pass through the second mounting cavity 10B and the third mounting cavity 10C.
[0056] Based on this, the film and television light 100 also includes a first sealing joint 82 and a second sealing joint 83. The first sealing joint 82 is connected to the first mounting shell 11 and is correspondingly set to the first wire passage 113. The second sealing joint 83 is connected to the third mounting shell 15 and is correspondingly set to the second wire passage 152. In this way, the wire can be sealed through the first sealing joint 82 and the second sealing joint 83.
[0057] Understandably, the first sealing joint 82 has a first wire passage 113, and a fifth sealing groove is recessed on one side of the first sealing joint 82. The bottom wall of the fifth sealing groove is further recessed to form a first receiving groove, and a sixth sealing groove is recessed on the other side of the first sealing joint 82. The fifth sealing groove, the first receiving groove, and the sixth sealing groove are respectively connected to the first wire passage 113. The video lamp 100 also includes a first terminal block and a fourth sealing ring. The first terminal block is disposed in the first receiving groove, and one side is connected to the wire for connecting to the drive board 40, and the other side is connected to the wire for connecting to the control board 50. The fourth sealing ring is disposed in the fifth sealing groove and abuts against the outer wall of the first mounting shell 11. The sixth sealing groove is filled with potting compound, thus achieving a seal.
[0058] The second sealing joint 83 has a second wire passage 152, and a seventh sealing groove is recessed on one side of the second sealing joint 83. The bottom wall of the seventh sealing groove is further recessed to form a second receiving groove, and an eighth sealing groove is recessed on the other side of the second sealing joint 83. The seventh sealing groove, the second receiving groove, and the eighth sealing groove are respectively connected to the second wire passage 152. The video light 100 also includes a second terminal block and a fifth sealing ring. The second terminal block is disposed in the second receiving groove, and one side is connected to the wire for connecting to the control board 50, and the other side is connected to the wire for connecting to the drive board 40, that is, the wire passing through one side of the first terminal block is connected. The fifth sealing ring is disposed in the seventh sealing groove and abuts against the outer wall of the third mounting shell 15. The eighth sealing groove is filled with potting compound, thus achieving a seal.
