[0033] In order to make the purpose, technical solutions and advantages of this application clearer, the following part will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0034] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application, as detailed in the appended claims.

[0035] In the description of this application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances. In addition, in the description of this application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0037] Please refer to Figures 1-4 The present application proposes a film and television lamp 100 , which includes a COB light source 20 , a control drive component 30 and a housing 10 .

[0038] The COB light source 20 includes a metal substrate and multiple LED chips, which are packaged on the metal substrate to form a high-density, high-power integrated light source. In this embodiment, the COB light sources 20 include multiple COB light sources, meaning that the film and television light 100 has multiple independent light sources. The multiple COB light sources 20 can be arranged in a matrix. In this way, the multiple COB light sources 20 can be used to increase the power of the film and television light 100. It can be understood that the film and television light 100 of this embodiment integrates multiple COB light sources 20. For example, the number of COB light sources 20 can be four, so the film and television light 100 is actually a four-head light, and the four COB light sources 20 can be configured to achieve a power of 2500W. Of course, this embodiment is not limited to this. The number of COB light sources 20 can also be nine or twelve, etc., and the corresponding number of COB light sources 20 can be selected according to the actual power required by the film and television light 100.

[0039] The control and drive assembly 30 is electrically connected to the multiple COB light sources 20. Its function is to output power to the COB light sources 20 and provide control instructions to the COB light sources 20, enabling them to change their operating states. Thus, in this embodiment, the cinema light 100 does not require an external power source for control. By integrating the control and drive assembly 30 within the cinema light 100, the overall structure of the cinema light 100 is enhanced. In actual use, only the power cord needs to be connected to the cinema light 100, eliminating the need for an external power supply box. This makes operation easier and effectively improves the user experience.

[0040] The housing 10 can be made of metal, such as a magnesium alloy. Magnesium alloys offer advantages such as light weight and high strength, and the material of the housing 10 is not specifically limited herein. The housing 10 defines a receiving cavity 10A for accommodating a plurality of COB light sources 20, which are arranged in a matrix within the receiving cavity 10A. A receiving slot 10B is formed within the housing 10, located outside the receiving cavity 10A and accommodating the control drive assembly 30.

[0041] The housing 10 is an integrally molded component. For example, a mold specifically designed for the housing 10 can be used to integrally mold the housing 10. Therefore, the technical solution of the present application utilizes the housing 10 as an integrally molded component, so that after the housing 10 is formed and manufactured, complicated assembly steps are not required and assembly errors are eliminated. This can reduce the assembly cost of the movie light 100 and effectively improve the production efficiency of the movie light 100. Furthermore, since the housing 10 does not have a connection structure such as a mortise and tenon structure, its own weight can be effectively reduced, thereby making the overall weight of the movie light 100 lighter.

[0042] Please refer to Figure 1-Figure 5 In some embodiments, the outer periphery of the housing 10 is square, for example, rectangular or square. This makes the housing 10 more regular, thereby effectively reducing mold costs and lowering the overall manufacturing cost of the cinema lamp 100.

[0043] In other embodiments, the outer peripheral contour of the housing 10 may also be set to be circular, which is not limited in this embodiment.

[0044] Please refer to Figure 1-Figure 5 In some embodiments, the film and television light 100 can be a dual-color temperature lamp, so the film and television light 100 can be adjusted between two different color temperatures, for example, it can be adjusted between 2700K and 6500K to meet different shooting needs of users.

[0045] Specifically, the control and drive assembly 30 includes a first power supply 31, a second power supply 32, a first control component 33, and a second control component 34. The first power supply 31 and the second power supply 32 are respectively electrically connected to the metal substrate of the COB light source 20 to power the COB light source 20. The first control component 33 is electrically connected to the first power supply 31 and the COB light source 20 to drive some of the LED chips in the COB light source 20 to emit warm light. The second control component 34 is electrically connected to the second power supply 32 and the COB light source 20 to drive the remaining LED chips in the COB light source 20 to emit cold light. One of the first control component 33 and the second control component 34 includes a first driver board and a control circuit board, and the first driver board can drive the COB light source 20. The other includes a second driver board, and the second driver board can drive the COB light source 20.

[0046] The housing 10 includes four side shell parts 11, which are connected end to end to form an integral structure. The four side shell parts 11 cooperate to form a receiving cavity 10A, and each side shell part 11 has a receiving groove 10B formed therein.

[0047] The receiving slots 10B of the four side shell portions 11 are used to accommodate the first power supply 31, the second power supply 32, the first control component 33, and the second control component 34 in a one-to-one correspondence. Thus, based on the dual-color temperature lamp 100, the four side shell portions 11 of the housing 10 can be used to accommodate multiple components of the control drive assembly 30, making the installation layout more reasonable.

[0048] Please refer to Figure 2-Figure 5 In some embodiments, each side shell portion 11 includes a side shell body 111 and a cover plate 112. Based on the cooperation between the side shell body 111 and the cover plate 112, the outline of the outer periphery of the shell 10 is set to be square.

[0049] The material of the side shell body 111 can be a magnesium alloy. The magnesium alloy material makes the side shell body 111 have the advantages of light weight and high strength. The material of the shell 10 is not specifically limited here. The side shell body 111 is provided with an opening 111A. The material of the cover plate 112 can be carbon fiber. The carbon fiber makes the cover plate 112 have the advantages of light weight, high modulus and high strength. The cover plate 112 is covered on the opening 111A to cooperate with the side shell body 111 to construct the accommodating groove 10B, that is, the cover plate 112 constructs the groove top wall of the accommodating groove 10B, and the side shell body 111 constructs the groove side walls and groove bottom wall of the accommodating groove 10B.

[0050] The cover plate 112 is detachably connected to the side shell body 111. The detachable connection may be a threaded connection, a snap connection, or a magnetic connection, which is not limited in this embodiment. This arrangement allows the cover plate 112 to be removed from the side shell body 111 when the control drive assembly 30 needs to be replaced or repaired, thereby simplifying the operation and facilitating maintenance and replacement by the operator.

[0051] Please refer to Figure 4-Figure 6 Furthermore, the cover plate 112 and the side shell body 111 are connected by a threaded connection. Specifically, the side wall of the side shell body 111 is provided with a first threaded column 1111. The first threaded column 1111 and the side shell body 111 can be an integral structure or a split structure, which is not limited in this embodiment.

[0052] A first internal thread is formed inside the first threaded column 1111, and a through hole 112A is formed in the cover plate 112. The housing 10 further includes a first threaded member (not shown) having a first external thread that mates with the first internal thread. The first threaded member is sequentially inserted through the through hole 112A and the first threaded column 1111 to allow the cover plate 112 to be detachably connected to the side housing body 111. This facilitates the removal of the cover plate 112 from the side housing body 111 while ensuring a stable connection between the two.

[0053] See also Figure 6 Furthermore, the first threaded column 1111 is integrally formed on the side wall of the side shell body 111. In this way, the first threaded column 1111 can be manufactured by an integral molding method, which not only reduces the assembly steps but also ensures the connection strength between the first threaded column 1111 and the side shell body 111.

[0054] Please refer to Figure 4-Figure 6 In some embodiments, the control drive assembly 30 is detachably connected to the side shell body 111. Specifically, a second threaded column 1112 is protruded from the bottom wall of the accommodating groove 10B, and a second internal thread is formed inside the second threaded column 1112.

[0055] The cover plate 112 is provided with a through opening 112A, and the shell 10 further includes a second threaded member (not shown in the figure), which has a second external thread that cooperates with the second internal thread. The second threaded member is sequentially passed through the control drive assembly 30 and the second threaded column 1112, so that the control drive assembly 30 can be detachably connected to the side shell portion 11.

[0056] With this arrangement, when the control drive assembly 30 needs to be disassembled for maintenance or replacement, the threaded fit between the second external thread and the second internal thread can be directly released, thereby removing the control drive assembly 30 from the housing 10. The operation is convenient, and the threaded connection can ensure the stability of the connection between the control drive assembly 30 and the housing 10.

[0057] Please refer to Figure 2-Figure 6 In some embodiments, the sidewall of the side housing body 111 of each side housing portion 11 is provided with a wire passage 11A. This passage 11A is used to connect the receiving slots 10B of any two adjacent side housing portions 11. This arrangement allows the wires of the first power supply 31, the second power supply 32, the first control component 33, and the second control component 34 to pass directly through the wire passage 11A, eliminating the need for the wires to pass through the receiving cavity 10A. This allows the wires to be protected and concealed by the housing 10, enhancing the overall appearance of the cinema light 100.
