Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lamps, in particular to a lighting device with an inclined control shell. BACKGROUND

[0002] In the design of conventional lighting devices with an inclined control shell, the layout of the control board often has the problem of insufficient space utilization. The prior art usually adopts a fixed mode of parallel installation of the control board and the shell. Although this conventional layout is convenient for standardized production, it does not fully consider the three-dimensional utilization of the internal space of the lamp. The conventional parallel installation mode causes unnecessary gaps between the control board and the shell, which not only wastes valuable internal space but also increases the overall volume of the lamp. In addition, this layout mode also easily causes confusion in the arrangement of lines, affecting the smoothness of the heat dissipation air duct. SUMMARY

[0003] Therefore, the present application provides a lighting device with an inclined control shell. The installation direction of the control board is adapted to the control shell, which fully utilizes the internal space and is conducive to compressing the overall volume of the device. The inclined space between the power board and the control board is relatively larger, which is conducive to more airflow passing through, thereby helping the side surface of the power board close to the control board to dissipate heat through the airflow.

[0004] A lighting device with an inclined control shell includes a shell, a lamp bead plate, a heat sink assembly, a heat dissipation fan, a power board, and a control board.

The control board is located between the control shell and the power board. The control board and the power board are inclined. The lamp bead plate, the power board, and the control board are sequentially electrically connected.

[0005] The above lighting device with an inclined control shell has the control shell inclined relative to at least one side of the side shell. The installation direction of the control board is adapted to the control shell, which can fully utilize the internal space and is conducive to compressing the overall volume of the device. The heat sink assembly contacts the lamp bead plate, which can quickly conduct heat away from the lamp bead plate through contact heat transfer. The heat dissipation fan is installed on the side shell, which forms a forced air cooling system with the heat sink assembly, thereby improving the heat dissipation efficiency. The inclined space between the power board and the control board is relatively larger, which is conducive to more airflow passing through, thereby helping the side surface of the power board close to the control board to dissipate heat through the airflow.

[0006] In one embodiment, the power board is vertically disposed between each of the side shells, and the tilt angle between the power board and the control board is 10° to 20°.

[0007] In one embodiment, the heat sink assembly includes a front panel, heat sink fins, a rear panel, and multiple heat pipes. The front panel, the heat sink fins, and the rear panel are connected in sequence. One end of each heat pipe is connected to the front panel, and the other end passes through the heat sink fins. The LED board is fixed to the front panel, and the exhaust side of the cooling fan faces the heat sink fins.

[0008] In one embodiment, the power board is fixed to the rear plate, and the LED board, the front plate, the rear plate, and the power board are arranged parallel to each other.

[0009] In one embodiment, the arrangement direction between the cooling fan and the cooling fins is perpendicular to the arrangement direction between the front panel and the rear panel.

[0010] In one embodiment, a lamp board bracket is also included, the lamp board bracket being fixed to the side shell, and the lamp bead board being fixedly connected between the lamp board bracket and the front plate.

[0011] In one embodiment, the lampshade and a dust cover are also included. The lampshade is fixed to the side shell and the portion of the lampshade extends curvedly to the side of the lamp board bracket away from the lamp bead plate. The dust cover is fixedly connected to the side of the lamp board bracket away from the lamp bead plate and faces the light-emitting side of the lamp bead plate.

[0012] In one embodiment, a silicone ring is also included, which is fixedly connected between the lamp plate bracket, the dustproof plate, and the lamp cover.

[0028] In the design of traditional lighting fixtures with tilted control housings, the layout of the control panel often suffers from insufficient space utilization. Existing technologies typically employ a fixed configuration 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 internal space of the luminaire. Especially in luminaire structures with tilted control housings, the traditional parallel mounting method creates unnecessary gaps between the control panel and the housing, wasting valuable internal space and increasing the overall size of the luminaire. Furthermore, this layout easily leads to chaotic wiring and affects the unobstructed flow of heat dissipation airflow. With the increasing trend towards miniaturization and portability in film and television lighting equipment, how to reduce equipment size while ensuring heat dissipation performance has become a key technical challenge for the industry.

[0029] See Figures 1-7To address the aforementioned issues, this application provides a lighting device 10 with a tilt-adjustable housing, suitable for various application scenarios. Specifically, the lighting device 10 with a tilt-adjustable housing includes a housing 20, an LED chip plate 30, a heat sink assembly 40, a cooling fan 50, a power supply board 60, and a control board 70. The housing 20 includes a control shell 21 connected to each other and multiple side shells 22. The side shells 22 and the control shell 21 form a mounting cavity 23. The control shell 21 is tilted relative to at least one side shell 22. The LED chip plate 30, the heat sink assembly 40, the cooling fan 50, the power supply board 60, and the control board 70 are all located in the mounting cavity 23. The LED chip plate 30 and the cooling fan 50 are fixed to the side shells 22. The power supply board 60 is fixed to the heat sink assembly 40. The control board 70 is fixed and parallel to the control shell 21. The control board 70 is located between the control shell 21 and the power supply board 60, and the control board 70 and the power supply board 60 are tilted together. The LED chip plate 30, the power supply board 60, and the control board 70 are electrically connected sequentially.

[0030] Specifically, in this embodiment, the lighting device 10 with a tilting control shell includes a housing 20, an LED chip plate 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 shell 21 and multiple side shells 22, forming a closed mounting cavity 23 to protect the internal components. The control shell 21 is tilted, forming a certain angle with some of the side shells 22, which facilitates the installation and operation of the control board 70, while optimizing the utilization of internal space.

[0031] Furthermore, the LED chip board 30, heat sink assembly 40, cooling fan 50, power board 60, and control board 70 are all located in the mounting cavity 23. The LED chip board 30 can be fixed on the side shell 22, using high-brightness LED chips to provide a stable and uniform light source output. The heat sink assembly 40 is in contact with the LED chip board 30, enabling heat transfer through contact, allowing the heat from the LED chip board 30 to be quickly dissipated, ensuring that the brightness of the lamp does not decrease during long-term operation. The cooling fan 50 is mounted on the side shell 22, forming a forced air cooling system with the heat sink assembly 40, which can improve heat dissipation efficiency. The fan wire passes through the wire notch on the power board 60 and connects to the control board 70. To achieve a sealed and waterproof finish, sealant silicone is applied to the wire notch. The power board 60 is fixed on the heat sink assembly 40 and is responsible for power supply management to ensure stable current output. The control board 70 is installed parallel to the inside of the control shell 21, and the control board 70 and the power board 60 are arranged at an angle, enabling intelligent adjustment of parameters such as light brightness and color temperature. The mounting direction of the control board 70 is adapted to the control housing 21, making full use of the internal space and helping to reduce the overall size of the equipment. The components inside the lighting device 10 with the tilted control housing are electrically connected. Specifically, the lamp bead board 30, the power supply board 60, and the control board 70 are sequentially electrically connected to form a power supply and control link, thereby ensuring the stable operation of the lighting device 10 with the tilted control housing. In the above scheme, the constant-temperature lamp uses a dual heat dissipation scheme of heat sink assembly 40 and cooling fan 50, which can effectively reduce the temperature of the lamp beads and extend their service life. At the same time, the power supply board 60 is directly fixed to the heat sink, which can prevent high temperatures from affecting the stability of electronic components. The control housing 21 is tilted relative to at least one side housing 22, so that the control board 70 and the power supply board 60 form an angle, which can reduce signal interference and thus improve circuit stability.

[0032] Furthermore, in this embodiment, the power board 60 is vertically positioned relative to each side shell 22. This vertical positioning not only fully utilizes the internal space of the shell 20 but also ensures a stable connection between the power board 60 and the shell 20. Simultaneously, this vertical positioning facilitates neat cable routing, effectively avoiding potential heat dissipation problems or signal interference caused by messy wiring. Preferably, the tilt angle between the power board 60 and the control board 70 is 10° to 20°, and placing the control board 70 at an angle facilitates mold ejection. In one embodiment, the tilt 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 via a flexible circuit board. The flexible circuit board connects the control board 70 and the power board 60, and the connector is located on the upper side of the flexible circuit board. The connector can be staggered to ensure a reliable connection. The tilted layout between the power board 60 and the control board 70 creates a heat dissipation channel between the two circuit boards, which helps natural air convection. The aforementioned angle range ensures the stability of control signal transmission and avoids electromagnetic interference. At the same time, this non-parallel board relationship provides a more convenient operating space for maintenance and testing, making it easier for users to maintain and repair the lighting device 10 with the tilt control housing.

[0033] To improve the heat dissipation performance of the lighting device 10 with tilt-adjustable housing, the heat sink assembly 40 includes a front plate 51, heat dissipation fins 52, a rear plate 53, and multiple heat pipes 54. Specifically, the front plate 51 serves as the front-end carrier of the heat sink assembly 40, and can directly contact the LED chip plate 30 to promptly dissipate the heat generated by the LED chip plate 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 LED chip plate 30 can be quickly conducted to the entire heat sink assembly 40. The heat dissipation fins 52 can be made of aluminum alloy and can form a wave-shaped three-dimensional arrangement structure. Each group of fins is radially distributed, and 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 fin thickness of 0.3 mm. The edges of each group of fins adopt an arc-shaped tapering design to guide the airflow to form a vortex effect. The rear plate 53 serves as the supporting frame for the entire heat sink assembly 40, ensuring the stability of the lighting device 10 with its tilt-adjustable housing while also aiding in heat dissipation. The rear plate 53 of the heat sink assembly 40 is made of aluminum, and its protruding ribs are formed by extrusion molding of the profile; bending is not used due to space constraints. Multiple heat pipes 54 penetrate the heat sink assembly 40, with one end tightly connected to the front plate 51 and the other end passing through the heat dissipation fins 52. This allows heat to be conducted from the heat source to the end of the heat dissipation fins 52 through the interior of the heat pipes 54, achieving heat dissipation. The rear plate 53 and the multiple heat pipes 54 are connected in series, with the heat pipes 54 welded to the heat dissipation fins 52. The heat pipes 54 are evenly distributed on the heat dissipation fins 52. The front plate 51, rear plate 53, and heat dissipation fins 52 are securely soldered together to form a single unit, with the large flat surface of the rear plate 53 flush with the power board 60.

[0034] Meanwhile, the exhaust side of the cooling fan 50 directs airflow directly onto the heat dissipation fins 52 to form a directional airflow. This directional airflow effectively removes heat from the surface of the heat dissipation fins 52, creating a forced convection cooling effect. The combined action of the heat sink assembly 40 and the cooling fan 50 provides good heat conduction performance for the lighting device 10 with the tilt control housing, while also facilitating maintenance and upkeep. This allows the lighting device 10 with the tilt control housing to maintain stable temperature performance even under prolonged high-load operation, thereby significantly extending its service life and maintaining light output quality. By setting a relatively larger tilt space between the power board 60 and the control board 70, more airflow is facilitated, which helps dissipate heat from the side of the power board 60 closest to the control board 70.

[0035] In some embodiments, the power board 60 is fixed to the rear plate 53, and 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 with fasteners, which ensures structural strength and establishes a heat conduction path. The LED chip board 30, front plate 51, rear plate 53, and power board 60 are arranged in parallel to each other. The heat generated by the LED chip board 30 is first conducted to the front plate 51, which is in close contact with it, and then quickly transferred to the area of ​​the rear plate 53 through the heat pipe 54. The parallel layout not only improves the utilization of internal space and reduces the thickness of the equipment, but also forms a uniform heat diffusion channel, which is conducive to the stepped conduction of heat and avoids local overheating.

[0036] In some embodiments, the arrangement direction between the cooling fan 50 and the heat dissipation fins 52 is perpendicular to the arrangement direction between the front panel 51 and the rear panel 53. The cooling fan 50, the heat dissipation fins 52, and the heat conduction direction formed by the front panel 51 and the rear panel 53 constitute a three-dimensional heat dissipation structure. This structure can achieve dual heat dissipation. On the one hand, heat is longitudinally conducted along the direction of the front panel 51 and the rear panel 53 through the heat pipe 54. On the other hand, the airflow generated by the cooling fan 50 passes laterally through the entire heat dissipation fins 52 in a vertical direction. The three-dimensional heat dissipation structure breaks through the limitations of traditional parallel heat dissipation, allowing the cooling airflow to penetrate the gaps between each heat dissipation fin 52 with a short path, ensuring that there are no dead zones in heat dissipation. In one embodiment, the air outlet is directly facing the relatively hot area of ​​the heat dissipation fins 52, and the airflow direction is perpendicular to the gaps between the heat dissipation fins 52, so that the cooling air can pass evenly through the entire surface of the heat dissipation fins 52, maximizing the utilization rate of the airflow. At the same time, the vertical airflow method avoids the phenomenon of airflow slippage on the surface of the heat dissipation fins 52, ensuring that the airflow can effectively dissipate heat. The above process enables the lighting device 10 with tilt control shell to achieve effective heat dissipation performance in a limited space, and ensures that the lamp can maintain stable light output even under long-term high-load operation.

[0037] Furthermore, in this embodiment, the lighting device 10 with the tilt-adjustable housing also includes a lamp plate bracket 90, which is fixed to the side shell 22. The lamp plate bracket 90 can form a rigid connection with the side shell 22 of the lighting device 10 with the tilt-adjustable housing through a multi-point locking structure, ensuring the overall stability and shock resistance of the lighting device 10 with the tilt-adjustable housing. Specifically, the lamp bead plate 30 is fixedly connected between the lamp plate bracket 90 and the front plate 51. The close contact between the lamp bead plate 30 and the front plate 51 effectively absorbs mechanical vibration through the buffering effect of the lamp plate bracket 90. The installation angle and height of the lamp plate bracket 90 can be finely adjusted to facilitate precise calibration of the light emission direction of the lamp beads. The edge of the lamp plate bracket 90 is provided with quick-release buckles, allowing for simple replacement or maintenance of the lamp bead plate 30, effectively improving the maintainability of the product. Furthermore, the lighting device 10 with a tilt-adjustable housing also includes a lampshade 81 and a dustproof plate. The lampshade 81 is fixed to the side shell 22, and part of the lampshade 81 bends and extends to the side of the lamp plate bracket 90 away from the lamp bead plate 30. The lampshade 81 can extend to cover the back of the lamp plate bracket 90 to form a light guiding channel, ensuring uniform and soft light output. The dustproof plate is installed on the backlight surface of the lamp plate bracket 90, parallel to the light-emitting surface of the lamp bead plate 30. The dustproof plate has light transmission and filtering properties, effectively blocking dust, lint, and other fine particles from entering the interior of the lighting device 10 with a tilt-adjustable housing, while ensuring light transmission. In one embodiment, the lighting device 10 with a tilt-adjustable housing also includes glass, with a silicone ring 83 located between the lampshade 81 and the glass. The silicone ring 83 wraps around the glass in the vertical direction, which better protects the glass and provides sufficient buffer space for the glass to withstand external impacts. The dustproof plate is treated with antistatic agents to prevent dust adsorption, thereby keeping the lighting device 10 with a tilt-adjustable housing clean. The extended portion of the lampshade 81 forms a nested structure with the dustproof plate. The outer layer of the lampshade 81 is responsible for protecting against large particles and physical impacts, while the inner layer of the dustproof plate focuses on filtering fine dust. The air layer between the two forms a natural convection channel, which not only assists in heat dissipation but also prevents condensation inside the lighting device 10 with its tilt control housing.

[0038] In some embodiments, the lighting device 10 with a tilt-adjustable housing further includes a silicone ring 83, which is fixedly connected between the lamp plate bracket 90, the dustproof plate, and the lampshade 81. The silicone ring 83 forms an interference fit with the inner wall of the lampshade 81, and one side of the silicone ring 83 tightly engages with the edge of the dustproof plate. The silicone ring 83, placed inside the lighting device 10 with a tilt-adjustable housing, effectively prevents external dust and moisture from entering the interior of the lighting device 10. Simultaneously, the silicone ring 83 can absorb vibrations and stress between components and compensate for differences in thermal expansion and contraction between different materials. During installation, the silicone ring 83 can be pre-compressed and embedded between the lamp plate bracket 90, the dustproof plate, and the lampshade 81, maintaining appropriate clamping force.

[0039] To improve the directional projection function of the LED bead plate 30 in the lighting device 10 with tilt control housing, a reflector is provided in the lighting device 10 with tilt control housing. The reflector is fixed to the side shell 22 and can converge and directionally project the light emitted by the LED bead plate 30. A dustproof plate is located between the reflector and the LED bead plate 30, with the light-emitting side of the LED bead plate 30 facing the reflector. The dustproof plate between the LED bead plate 30 and the reflector protects the inner wall of the reflector from contamination without affecting the effective reflection of light. The light-emitting center of the LED bead plate 30 and the focal position of the reflector can be calibrated to ensure that the light emitted by the LEDs can be captured and directionally reflected by the reflector. The reflector can effectively eliminate stray light and form a uniform and soft beam distribution.

[0040] In some embodiments, a light-mixing cup 85 is provided in the lamp panel bracket 90. The light-mixing cup 85 can effectively eliminate the inherent graininess of LED beads, creating a soft and uniform lighting effect. The light-mixing cup 85 has a conical structure and includes a narrow end 851 and a wide end 852 along the axial direction. The narrow end 851 surrounds the LED bead plate 30, and the wide end 852 is fixed to the end of the lamp panel bracket 90 away from the LED bead plate 30. The housing 20 and the light-mixing cup 85 are made of die-cast aluminum and are fixed and locked by two symmetrical long screws, which can increase the overall strength and improve the rigidity of the lighting device 10 with tilt control housing. The light-mixing cup 85 is installed in the light-mixing frame 853 and is clamped by four flat clips and two clip bases on the lower end face to achieve a non-loosening effect. Specifically, the narrow end 851 of the light mixing cup 85 tightly surrounds the LED bead plate 30, and a honeycomb-shaped closing structure can be used to ensure precise alignment with each LED bead. The wide end 852 can be securely installed at the far end of the lamp plate bracket 90 through a snap-fit ​​structure, forming a light diffusion channel. The gradually expanding structure allows the light to undergo multiple reflections and refractions during transmission, achieving thorough mixing.

[0041] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
