Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to a lighting device with a tilt-adjustable shell. Background Art

[0002] In traditional lighting fixtures with tiltable control housings, the layout of the control panel often suffers from insufficient space utilization. Existing technologies typically employ a fixed layout where the control panel is mounted parallel to the housing. While this conventional layout facilitates standardized production, it fails to fully consider the three-dimensional utilization of the lamp's internal space. The traditional parallel mounting method creates an unnecessary gap between the control panel and the housing, wasting valuable internal space and increasing the overall size of the lamp. Furthermore, this layout can easily lead to cluttered wiring and compromise the smooth flow of heat dissipation ducts. Summary of the Invention

Those skilled in the art can reasonably determine the specific meanings of these terms in the present invention based on the specific content of the technical solution.

[0021] In the design of traditional lighting devices with tilted control shells, the layout of the control panel often has the problem of insufficient space utilization. The existing technology usually adopts a fixed mode in which the control panel is installed parallel to the shell. Although this conventional layout method is convenient for standardized production, it fails to fully consider the three-dimensional utilization of the internal space of the lamp. Especially in the lamp structure with a tilted control shell, the traditional parallel installation method will cause unnecessary gaps between the control panel and the shell, which not only wastes valuable internal space but also increases the overall volume of the lamp. In addition, this layout method is prone to causing confusion in the wiring arrangement and affecting the smoothness of the heat dissipation duct. As the trend of film and television lighting equipment towards miniaturization and portability is becoming increasingly obvious, how to compress the equipment volume while ensuring heat dissipation performance has become a technical difficulty in the industry.

[0022] See Figures 1 to 7, in order to solve the above problems, the embodiment of the present application provides a lighting device 10 with a tilted control shell, which is suitable for different application scenarios. Specifically, the lighting device 10 with a tilted control shell includes a shell 20, a lamp bead board 30, a radiator assembly 40, a cooling fan 50, a power board 60 and a control board 70. The shell 20 includes a control shell 21 and multiple side shells 22 connected to each other. The side shells 22 and the control shell 21 are surrounded by a mounting cavity 23, and the control shell 21 is tilted relative to the side shell 22 on at least one side; the lamp bead board 30, the radiator assembly 40, the cooling fan 50, the power board 60 and the control board 70 are all located in the mounting cavity 23; the lamp bead board 30 and the cooling fan 50 are fixed to the side shell 22; the power board 60 is fixed to the radiator assembly 40; the control board 70 is fixed and parallel to the control shell 21, and the control board 70 is located between the control shell 21 and the power board 60, and the control board 70 is tilted to the power board 60; the lamp bead board 30, the power board 60 and the control board 70 are electrically connected in sequence.

[0023] Specifically, in this embodiment, the lighting device 10 with a tilted control housing includes a housing 20, a lamp board 30, a heat sink assembly 40, a cooling fan 50, a power supply board 60, and a control board 70. The housing 20 is composed of a control housing 21 and multiple side housings 22, forming an enclosed mounting cavity 23 to protect the internal components. The control housing 21 is tilted, forming a certain angle with part of the side housing 22, facilitating the installation and operation of the control board 70 while optimizing internal space utilization.

[0024] Furthermore, the lamp bead board 30, the radiator assembly 40, the cooling fan 50, the power board 60 and the control board 70 are all located in the mounting cavity 23. The lamp bead board 30 can be fixed on the side shell 22 and uses high-brightness light-emitting diode lamp beads to provide a stable and uniform light output. The radiator assembly 40 is in contact with the lamp bead board 30 and can quickly dissipate heat from the lamp bead board 30 through contact heat transfer to ensure that the lamp does not lose brightness during long-term operation. The cooling fan 50 is installed on the side shell 22 and cooperates with the radiator assembly 40 to form a forced air cooling system, which can improve the heat dissipation efficiency. The fan line passes through the wire notch on the power board 60 and is connected to the control board 70. To achieve sealing and waterproofing, the wire notch is coated with sealing silicone glue. The power board 60 is fixed on the radiator assembly 40 and is responsible for power supply management to ensure stable current output. The control board 70 is installed parallel to the inner side of the control shell 21. The control board 70 and the power board 60 are arranged in an inclined manner, which can realize intelligent adjustment of parameters such as light brightness and color temperature. The installation direction of the control board 70 is adapted to the control shell 21, making full use of the internal space and helping to compress the overall volume of the device. The internal components of the lighting device 10 with a tilted control shell are electrically connected. Specifically, the lamp bead board 30, the power board 60 and the control board 70 are electrically connected in sequence to form a power supply and control link, thereby ensuring the stable operation of the lighting device 10 with a tilted control shell. In the above scheme, the constant lamp adopts a dual heat dissipation scheme of a radiator assembly 40 and a cooling fan 50, which can effectively reduce the temperature of the lamp beads and extend the service life. At the same time, the power board 60 is directly fixed on the radiator, which can avoid high temperature affecting the stability of electronic components. The control shell 21 is tilted relative to the side shell 22 on at least one side, so that the control board 70 and the power board 60 form an angle, which can reduce signal interference and thus improve circuit stability.

[0025] Furthermore, in the present embodiment, the power board 60 is vertically arranged between each side shell 22. The vertical arrangement can not only make full use of the internal space of the shell 20, but also ensure a stable connection between the power board 60 and the shell 20. At the same time, this vertical arrangement facilitates the regular routing of cables and can effectively avoid problems such as poor heat dissipation or signal interference that may be caused by cluttered lines. Preferably, the inclination angle between the power board 60 and the control board 70 is 10° to 20°, and the inclined placement of the control board 70 is conducive to mold demolding. In one embodiment, the inclination angle between the power board 60 and the control board 70 is 15°. In one embodiment, the control board 70 and the power board 60 are connected by plugging in a flexible circuit board. The flexible circuit board connects the control board 70 and the power board 60. The connector is arranged on the upper side of the flexible circuit board. The connector can be staggered to achieve reliable connection. The inclined layout between the power board 60 and the control board 70 can create a heat dissipation duct between the two circuit boards to facilitate natural air convection. The above-mentioned angle range can not only ensure the stability of control signal transmission, but also avoid electromagnetic interference. At the same time, this non-parallel relationship between the boards provides a more convenient operating space for maintenance and inspection, making it easier for users to maintain and repair the lighting device 10 with a tilted control shell.

[0026] In order to improve the heat dissipation performance of the lighting device 10 with a tilt control shell, the radiator assembly 40 includes a front plate 51, heat dissipation fins 52, a rear plate 53 and a plurality of heat pipes 54. Specifically, the front plate 51 serves as the front carrier of the radiator assembly 40. The front plate 51 can be in direct contact with the lamp bead board 30 to promptly conduct away the heat generated by the lamp bead board 30 during operation. In one embodiment, the front plate 51 can be made of a high thermal conductivity material to ensure that the heat generated by the lamp bead board 30 can be quickly conducted to the entire radiator assembly 40. The heat dissipation fins 52 can be made of aluminum alloy. The heat dissipation fins 52 can form a wavy three-dimensional arrangement structure. Each group of fins is radially distributed. The spacing between adjacent fins can ensure that the heat dissipation area is increased while ensuring smooth airflow. In one embodiment, the heat dissipation fins 52 are composed of 48-60 ultra-thin fins, with a single piece thickness of 0.3 mm. The edges of each group of fins adopt an arc-shaped closing design to guide the airflow to form a vortex effect. The rear plate 53 serves as the supporting skeleton of the entire radiator assembly 40, ensuring the stability of the lighting device 10 with a tilt-controlled shell while assisting in heat dissipation. The rear plate 53 of the radiator assembly 40 is made of aluminum, and the raised ribs of the rear plate 53 are formed by extrusion of a profile. Due to limited space, no bending process is used. Multiple heat pipes 54 run through the radiator assembly 40. One end of the heat pipe 54 is tightly connected to the front plate 51, and the other end runs through the heat dissipation fins 52, allowing heat to pass through the inside of the heat pipe 54 and be conducted from the heat source to the end of the heat dissipation fin 52 to achieve heat diffusion. The rear plate 53 is connected in series with the multiple heat pipes 54, wherein the heat pipes 54 are welded and fixed to the heat dissipation fins 52, and the heat pipes 54 are evenly arranged on the heat dissipation fins 52. The front plate 51, the rear plate 53 and the heat dissipation fins 52 are firmly fixed by soldering to form an integral part, wherein the large surface of the rear plate 53 is fixed and flush with the power board 60.

[0027] At the same time, the outlet side of the cooling fan 50 blows air directly toward the cooling fins 52, creating a directional airflow. This directional airflow effectively removes heat from the surface of the cooling fins 52, creating a forced convection cooling effect. The combined action of the radiator assembly 40 and the cooling fan 50 provides better thermal conductivity for the lighting device 10 with a tilted control housing, while facilitating maintenance and sample preservation. This allows the lighting device 10 with a tilted control housing to maintain a stable temperature even under long-term, high-load operating conditions, significantly extending its service life and maintaining light output quality. By making the tilted space between the power board 60 and the control board 70 relatively larger, more airflow is facilitated, thereby helping the side surface of the power board 60 close to the control board 70 to dissipate heat through airflow.

[0028] In some embodiments, the power board 60 is fixed to the rear plate 53. The power board 60 and the rear plate 53 of the heat sink assembly 40 are rigidly connected. The power board 60 is fixed to the rear plate 53 by fasteners, which not only ensures structural strength but also establishes a heat conduction path. The lamp bead board 30, the front plate 51, the rear plate 53, and the power board 60 are arranged parallel to each other. The heat generated by the lamp bead board 30 is first transferred to the front plate 51, which is closely fitted to it, and then quickly transferred to the rear plate 53 area through the heat pipe 54. The parallel layout not only improves the internal space utilization and compresses the thickness of the device, but also forms a uniform heat diffusion channel, which is conducive to the stepped conduction of heat and avoids local overheating.

[0029] In some embodiments, the arrangement direction between the cooling fan 50 and the cooling fins 52 is perpendicular to the arrangement direction between the front plate 51 and the rear plate 53. The cooling fan 50 and the cooling fins 52, together with the heat conduction direction formed by the front plate 51 and the rear plate 53, form a three-dimensional heat dissipation structure. This structure can achieve dual heat dissipation. On the one hand, heat is conducted longitudinally along the front plate 51 and the rear plate 53 through the heat pipe 54; on the other hand, the airflow generated by the cooling fan 50 passes horizontally through the entire cooling fin 52 in a vertical direction. This three-dimensional heat dissipation structure breaks through the limitations of traditional parallel heat dissipation, allowing the cooling airflow to penetrate the gaps between each cooling fin 52 in a short path, ensuring that there are no heat dissipation dead angles. In one embodiment, the air outlet is directly opposite the relatively hot area of ​​the cooling fin 52, and the airflow direction is perpendicular to the gaps between the cooling fins 52, so that the cooling air can pass evenly through the entire surface of the cooling fin 52, maximizing the utilization of the airflow. At the same time, the vertical air supply method avoids the phenomenon of airflow slipping on the surface of the cooling fin 52, ensuring that the airflow can effectively dissipate heat. The above process enables the lighting device 10 with the tilt-adjustable housing to achieve effective heat dissipation performance in a limited space, and can ensure that the lamp can maintain stable light output under long-term high-load operation.

[0030] Furthermore, in the present embodiment, the lighting device 10 with a tilt-controlled shell further includes a lamp panel bracket 90, which is fixed to the side shell 22. The lamp panel bracket 90 can form a rigid connection with the side shell 22 of the lighting device 10 with a tilt-controlled shell through a multi-point locking structure, thereby ensuring the overall stability and shock resistance of the lighting device 10 with a tilt-controlled shell. Specifically, the lamp bead board 30 is fixedly connected between the lamp panel bracket 90 and the front plate 51. The close contact between the lamp bead board 30 and the front plate 51 effectively absorbs mechanical vibrations through the buffering effect of the lamp panel bracket 90. The installation angle and height of the lamp panel bracket 90 can be fine-tuned to facilitate precise calibration of the light-emitting direction of the lamp beads. The edge of the lamp panel bracket 90 is provided with a quick-release buckle, and the replacement or maintenance of the lamp bead board 30 can be completed with simple operation, which can effectively improve the maintainability of the product. Furthermore, the lighting device 10 with a tiltable control shell also includes a lampshade 81 and a dustproof plate. The lampshade 81 is fixed to the side shell 22. The lampshade 81 partially bends and extends to the side of the lamp board bracket 90 away from the lamp bead board 30. The lampshade 81 can extend to cover the back of the lamp board bracket 90 to form a light guiding channel to ensure uniform and soft light output. The dustproof plate is installed on the backlight surface of the lamp board bracket 90, parallel to the light output surface of the lamp bead board 30. The dustproof plate has light transmittance and filtering properties, and can effectively block dust, flying catkins and other tiny particles from entering the interior of the lighting device 10 with a tiltable control shell, while ensuring the passage of light. In one embodiment, the lighting device 10 with a tiltable control shell is also provided with glass. The silicone ring 83 is located between the lampshade 81 and the glass. The silicone ring 83 wraps the glass in the middle in the upper and lower directions, which can better protect the glass and provide sufficient buffer space for the glass to be impacted by external forces. The dustproof plate is treated with anti-static treatment to prevent dust adsorption, thereby keeping the lighting device 10 with a tiltable control shell clean. The extended portion of the lampshade 81 forms a nested structure with the dust shield. The outer layer of the lampshade 81 protects against large particles and physical impact, while the inner layer of the dust shield filters fine dust. The air layer between the two creates a natural convection channel, which aids in heat dissipation and prevents condensation within the lighting device 10 with a tiltable housing.

[0031] In some embodiments, the lighting device 10 with a tilt-adjustable housing further includes a silicone ring 83, which is fixedly connected between the light panel bracket 90, the dust shield, and the lampshade 81. The silicone ring 83 forms an interference fit with the inner wall of the lampshade 81, with one side of the silicone ring 83 tightly engaging the edge of the dust shield. The placement of the silicone ring 83 within the lighting device 10 with a tilt-adjustable housing effectively blocks external dust and moisture from entering the interior of the lighting device 10 with a tilt-adjustable housing. Furthermore, the silicone ring 83 absorbs vibration and stress between components and compensates for differences in thermal expansion and contraction between different materials. During installation, the silicone ring 83 can be pre-compressed and inserted between the light panel bracket 90, the dust shield, and the lampshade 81, ensuring that the silicone ring 83 maintains an appropriate level of compression.

[0032] In order to improve the directional projection function of the lamp bead board 30 of the lighting device 10 with a tilt control shell, a reflective cup is provided in the lighting device 10 with a tilt control shell. The reflective cup is fixed to the side shell 22. The reflective cup can converge and directionally project the light emitted by the lamp bead board 30. The dustproof plate is located between the reflective cup and the lamp bead board 30, and the light-emitting side of the lamp bead board 30 faces the reflective cup. The dustproof plate is arranged between the lamp bead board 30 and the reflective cup, which not only protects the inner wall of the reflective cup from contamination, but also does not affect the effective reflection of light. The light-emitting center of the lamp bead board 30 and the focal position of the reflective cup can be calibrated to ensure that the light emitted by the lamp beads can be captured and directionally reflected by the reflective cup. The reflective cup can effectively eliminate stray light and form a uniform and soft beam distribution.

[0033] In some embodiments, a light mixing cup 85 is incorporated into the light panel bracket 90. This cup effectively eliminates the inherent graininess of LED lamp beads, creating a soft, uniform lighting effect. The cup 85 has a conical structure, axially comprising a narrow end 851 and a wide end 852. The narrow end 851 surrounds the lamp panel 30, while the wide end 852 is secured to the end of the light panel bracket 90 away from the lamp panel 30. The housing 20 and the cup 85 are constructed of die-cast aluminum and secured with two symmetrical long screws, enhancing overall strength and the rigidity of the lighting device 10 with a tilt-controllable housing. The cup 85 is mounted within the light mixing frame 853 and secured by four flat clips. Two clip-on bottoms on the lower end prevent loosening. Specifically, the narrow end 851 of the mixing cup 85 tightly surrounds the lamp board 30, employing a honeycomb-like closing structure to ensure precise alignment with each lamp bead. The wide end 852 securely attaches to the distal end of the lamp board bracket 90 via a snap-fit ​​mechanism, forming a light diffusion channel. This gradually expanding structure allows light to undergo multiple reflections and refractions during transmission, achieving thorough mixing.

[0034] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
