Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and more specifically, to a lighting fixture with a waterproof light source module. Background Technology

[0002] To achieve overall waterproofing, stage lights typically require the light source module to be housed in a waterproof box to prevent external water from entering the module. This additional accessory increases costs, and the cables supplying power and / or transmitting signals to the light source module must pass through the waterproof box. The cables and the waterproof box must be sealed with a sealing plug, and the connectors at the free ends of the cables also need to be waterproofed, making the process cumbersome. Utility Model Content

[0003] To overcome at least one of the defects described in the prior art, this utility model provides a waterproof lamp with a light source module, which can effectively solve the waterproofing problem of the power supply and / or signal transmission cables or connectors of the light source module.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a waterproof lamp with a light source module, including a lamp head having a receiving cavity and a partition dividing the receiving cavity into a heat dissipation cavity and an effect cavity. The heat dissipation cavity is connected to the external space of the lamp and has a light source module and a heat dissipation component for dissipating heat from the light source module installed inside. The effect cavity is isolated from the external space of the lamp and has an effect component for interfering with the emitted light of the light source module to produce a light effect. The light source module includes a sealed light source box, the light-emitting surface of the light source box is attached to the partition, the light-emitting surface has a light-transmitting part, and the partition is provided with a light-transmitting hole corresponding to the light-transmitting part. The light emitted by the light-emitting element of the light source module passes through the light-transmitting hole and is emitted from the light-emitting mirror on the effect cavity. The light source module also includes a connector disposed on the light-emitting surface for supplying power and / or sending signals to the light source module. A waterproof ring is provided around the light-transmitting hole and the connector between the partition and the light-emitting surface, and a plug hole is provided on the partition corresponding to the connector.

[0005] The waterproof luminaire with the light source module has a connector for supplying power and / or sending signals to the light source module located on the light-emitting surface of the light source box. This connector is exposed through the insertion hole within the effect cavity, which is isolated from the outside of the luminaire. The light-emitting surface is fitted with a partition that separates the receiving cavity to form the heat dissipation cavity and the effect cavity. The partition surrounds the light-transmitting hole between the light-emitting surface and the connector, and a waterproof ring is provided for the connector, thereby isolating the connector from the outside of the luminaire and achieving waterproofing. By simply plugging the connector into the cable inside the effect cavity, the light source module can be powered and / or controlled. The structure is simple, has fewer assembly steps, is low in cost, and has better waterproof stability.

[0006] Furthermore, the light-transmitting hole serves as the insertion hole, and the connector is exposed in the effect cavity through the light-transmitting hole. By directly utilizing the existing light-transmitting hole exposed in the effect cavity, there is no need to additionally set the insertion hole and the waterproof ring; the waterproof ring corresponding to the light-transmitting hole can be directly shared, which helps to save costs.

[0007] Furthermore, one of the waterproof rings simultaneously surrounds both the light-transmitting hole and the connector. Reducing the number of waterproof rings lowers assembly costs.

[0008] Furthermore, the light-emitting surface is provided with a receiving groove for accommodating the waterproof ring. This allows the waterproof ring to be securely clamped between the partition and the light source box, and facilitates the pre-installation of the waterproof ring into the light source box, making it easier to fix the light source box to the partition.

[0009] Furthermore, the light-emitting component includes a light-emitting unit and a metal-based circuit board that supplies power and / or transmits signals to the light-emitting unit. The light-emitting unit is fixed to the metal-based circuit board. The light source box has a mounting port, through which the light-emitting unit enters the interior of the light source box. The metal-based circuit board is located outside the light source box and blocks the mounting port. The heat-absorbing plate of the heat dissipation assembly is attached to the metal-based circuit board for heat dissipation. Utilizing the metal-based circuit board allows for better heat dissipation from the light-emitting unit to the heat-absorbing plate of the heat dissipation assembly, resulting in better heat dissipation. Furthermore, directly sealing the mounting port with the metal-based circuit board achieves waterproofing of the light source box without the need for an additional waterproof box, effectively reducing costs.

[0010] Furthermore, the light-emitting unit is an LED, and the light source module includes a red light-emitting element, a green light-emitting element, a blue light-emitting element, and a dichroic filter for filtering the three colors of light. In this way, the metal base circuit board corresponding to each color of the light-emitting element seals the corresponding mounting port and is attached to the heat-absorbing plate of the heat dissipation assembly, which improves the overall heat dissipation performance of the light source module.

[0011] Furthermore, the heat dissipation assembly includes heat dissipation fins and heat-conducting pipes connecting the heat dissipation fins and the heat absorption plate. The heat dissipation fins are arranged around the side of the light source box that connects to the light-emitting surface. The heat-conducting pipes conduct the heat absorbed by the heat absorption plate to the heat dissipation fins, thereby utilizing the heat dissipation fins for heat dissipation, resulting in a larger heat dissipation area and better performance.

[0012] Furthermore, the green light-emitting element is located on the side of the light source box away from the light-emitting surface. The heat absorption plates of the heat dissipation components corresponding to the red and blue light-emitting elements are connected to the heat absorption plate corresponding to the green light-emitting element or a heat transfer plate attached to it via heat transfer pipes. Since the green light-emitting element has the lowest luminous efficiency, it requires the highest power to emit light of the same brightness, thus generating more heat. The heat generated by the green light-emitting element is conducted to the heat absorption plates of the heat dissipation components corresponding to the red and blue light-emitting elements via the heat transfer pipes for auxiliary heat dissipation, thereby coordinating the overall heat dissipation performance of the light source module and improving overall temperature control.

[0013] Furthermore, the light-emitting unit is a laser diode, and the light source module also includes a phosphor wheel that receives the excitation light emitted by the light-emitting unit and converts it into laser-received light, and a heat-conducting plate for mounting the phosphor wheel and dissipating heat from it. The phosphor wheel enters the interior of the light source box through another mounting port, and the heat-conducting plate seals the mounting port. The heat-conducting plate dissipates the heat from the phosphor wheel, and by directly sealing the mounting port with the heat-conducting plate, the light source box can be waterproofed without the need for an additional waterproof box, effectively reducing costs.

[0014] Furthermore, it also includes a support arm for supporting the rotation of the lamp head and a housing for supporting the rotation of the support arm. Through the support arm and the housing, the lamp head can be rotated around two axes, thereby projecting the light beam in any direction.

[0015] Furthermore, there are two connectors, located on either side of the light source near the pivot joint between the lamp head and the support arm. The power supply and signal lines of the lamp head typically pass through the pivot joint between the lamp head and the support arm. Therefore, placing the connectors on either side of the light source near the pivot joint between the lamp head and the support arm facilitates connection and shortens the wiring harness length.

[0023] The accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0024] like Figures 1 to 4 This utility model provides a waterproof lamp with a light source module, including a lamp head 100 having a receiving cavity and a partition 130 dividing the receiving cavity into a heat dissipation cavity 110 and an effect cavity 120. The heat dissipation cavity 110 is connected to the external space of the lamp and houses a light source module 200 and a heat dissipation assembly 300 for dissipating heat from the light source module 200. The effect cavity 120 is isolated from the external space of the lamp and houses an effect assembly for interfering with the emitted light of the light source module 200 to produce a light effect. The light source module 200 includes a sealed light source box 210, and the light-emitting surface 211 of the light source box 210 is attached to the partition 130. The light-emitting surface 211 has a light-transmitting portion 212, and the partition 130 is provided with a light-transmitting hole 131 corresponding to the light-transmitting portion 212. The light emitted by the light-emitting element 220 of the light source module 200 passes through the light-transmitting hole 131 and is emitted from the light-emitting mirror 121 on the effect cavity 120. The light source module 200 also includes a connector 213 disposed on the light-emitting surface 211 for supplying power to the light source module 200 and / or sending signals. A waterproof ring 214 is provided around the light-transmitting hole 131 and the connector 213 between the partition 130 and the light-emitting surface 211. The partition 130 is provided with a plug hole corresponding to the connector 213.

[0025] The waterproof luminaire with the light source module has a connector 213 that supplies power and / or sends signals to the light source module 200 located on the light-emitting surface 211 of the light source box 210. This connector is exposed through the insertion hole within the effect cavity 120, which is isolated from the outside of the luminaire. The light-emitting surface 211 is fitted with a partition 130 that separates the receiving cavity to form the heat dissipation cavity 110 and the effect cavity 120. The partition 130 surrounds the light-transmitting hole 131 between the light-emitting surface 211 and the connector 213, which is also equipped with a waterproof ring 214. This effectively isolates the connector 213 from the outside of the luminaire, achieving waterproofing. Power and / or control of the light source module 200 can be achieved simply by connecting the connector 213 to the cable within the effect cavity 120. The structure is simple, requires fewer assembly steps, has low cost, and offers better waterproof stability.

[0026] Optionally, the effect components include one or more of the following: a magnifying lens, a focusing lens, a prism, a fogging plate, a CMY component, a cutting component, a rotating pattern disk component, a fixed pattern disk component, and a color filter disk component. These components respectively achieve functions such as beam divergence angle adjustment, beam sharpness adjustment, beam splitting, beam homogenization, beam color adjustment, beam cutting, pattern rotation, specific pattern creation, and beam coloring.

[0027] In this embodiment, the light-emitting lens 121 is located at the end of the effect cavity 120 away from the light source module 200, and the effect component is located between the light-emitting lens 121 and the light source module 200.

[0028] In this embodiment, the light-transmitting part 212 is disposed on the light-emitting surface 211 of the light-transmitting lens.

[0029] In a preferred embodiment of this invention, the light-transmitting hole 131 serves as the insertion hole, and the connector 213 is exposed through the light-transmitting hole 131 into the effect cavity 120. By directly utilizing the existing light-transmitting hole 131 exposed in the effect cavity 120, there is no need to additionally provide the insertion hole and the waterproof ring 214; the waterproof ring 214 corresponding to the light-transmitting hole 131 can be shared, which helps to save costs.

[0030] In this embodiment, the entire light-transmitting lens protrudes from the light-transmitting hole 131 and extends into the effect cavity 120.

[0031] In other embodiments, the insertion hole and the light-transmitting hole 131 can also be independent of each other.

[0032] In a preferred embodiment of this invention, one waterproof ring 214 simultaneously surrounds both the light-transmitting hole 131 and the connector 213. This reduces the number of waterproof rings 214 and lowers assembly costs. This method can be used whether the light-transmitting hole 131 serves as the insertion hole or the insertion hole and the light-transmitting hole 131 are independent of each other.

[0033] In other embodiments, one of the waterproof rings 214 may be used to surround the light-transmitting hole 131, and another waterproof ring 214 may be used to connect the connector 213. This method is generally used when the insertion hole and the light-transmitting hole 131 are independent of each other.

[0034] In a preferred embodiment of this invention, the light-emitting surface 211 is provided with a receiving groove for accommodating the waterproof ring 214. This allows the waterproof ring 214 to be securely clamped between the partition 130 and the light source box 210, and facilitates the pre-installation of the waterproof ring 214 on the light source box 210, making it easier to fix the light source box 210 to the partition 130.

[0035] In this embodiment, the partition 130 has a planar structure corresponding to the location of the receiving groove.

[0036] like Figure 5 In a preferred embodiment of this utility model, the light-emitting element 220 includes a light-emitting unit 221 and a metal base circuit board 222 that supplies power and / or sends signals to the light-emitting unit 221. The light-emitting unit 221 is fixed to the metal base circuit board 222. The light source box 210 has a mounting port 230. The light-emitting unit 221 enters the interior of the light source box 210 through the mounting port 230. The metal base circuit board 222 is located outside the light source box 210 and blocks the mounting port 230. The heat-absorbing plate 330 of the heat dissipation assembly 300 is attached to the metal base circuit board 222 to dissipate heat. The metal base circuit board 222 can better conduct the heat from the light-emitting unit 221 to the heat-absorbing plate 330 of the heat dissipation assembly 300, resulting in better heat dissipation. Furthermore, by directly blocking the mounting port 230 with the metal base circuit board 222, the light source box 210 can be waterproofed without the need for an additional waterproof box, effectively reducing costs.

[0037] Preferably, a sealing ring is provided between the metal base circuit board 222 and the mounting port 230 to achieve sealing of the mounting port 230.

[0038] In this embodiment, the light source box 210 is a hexahedron, and the mounting port 230 is located on any one of the faces of the light source box 210 other than the light-emitting surface 211.

[0039] In a preferred embodiment of this utility model, the light-emitting unit 221 is an LED, and the light source module 200 includes a red light-emitting element 220, a green light-emitting element 220, a blue light-emitting element 220, and a dichroic filter 240 for filtering the three colors of light. Thus, the metal base circuit board 222 corresponding to each color of the light-emitting element 220 respectively seals the corresponding mounting port 230 and is attached to the heat-absorbing plate 330 of the heat dissipation assembly 300, which can improve the overall heat dissipation performance of the light source module 200.

[0040] The dichroic filter 240 filters the light emitted by the red, green, and blue light-emitting elements 220, and finally allows the filtered light to be emitted from the light-transmitting part 212, thereby enabling the entire light source module 200 to emit colored light. The principle is similar to that of a projector light source, and will not be described in detail here.

[0041] like Figure 2 , Figure 3 In a preferred embodiment of this invention, the heat dissipation assembly 300 includes heat dissipation fins 310 and a heat-conducting pipe 320 connecting the heat dissipation fins 310 and the heat absorption plate 330. The heat dissipation fins 310 are arranged around the side of the light source box 210 connected to the light-emitting surface 211. The heat-conducting pipe 320 conducts the heat absorbed by the heat absorption plate 330 to the heat dissipation fins 310, thereby utilizing the heat dissipation fins 310 for heat dissipation, resulting in a larger heat dissipation area and better heat dissipation effect.

[0042] In this embodiment, the heat dissipation fins 310 form a continuous airflow channel surrounding the light emission direction of the light source module 200.

[0043] In this embodiment, a cooling fan 340 is also included to blow air to dissipate heat from the heat dissipation fins 310.

[0044] In a preferred embodiment of this utility model, the green light-emitting element 220 is located on the side of the light source box 210 away from the light-emitting surface 211. The heat absorption plates 330 of the heat dissipation assembly 300 corresponding to the red and blue light-emitting elements 220 are connected to the heat absorption plates 330 corresponding to the green light-emitting element 220 or the heat transfer plates 360 attached to them via heat transfer pipes 350. Since the green light-emitting element 220 has the lowest luminous efficiency, it requires the highest power to emit light of the same brightness, thus generating more heat. The heat generated by the green light-emitting element 220 is conducted to the heat absorption plates 330 of the heat dissipation assembly 300 corresponding to the red and blue light-emitting elements 220 via the heat transfer pipes 350 for auxiliary heat dissipation, thereby coordinating the overall heat dissipation performance of the light source module 200 and improving overall temperature control.

[0045] In this embodiment, the red and blue light-emitting elements 220 are located on the remaining four surfaces of the light source box 210, preferably on two opposite surfaces. The heat dissipation fins 310 corresponding to the green light-emitting element 220 are divided into two groups, respectively arranged close to the remaining two surfaces.

[0046] In a preferred embodiment of this invention, the light-emitting unit 221 is a laser diode. The light source module 200 further includes a phosphor wheel that receives the excitation light emitted by the light-emitting unit 221 and converts it into a laser-received phosphor wheel, and a heat-conducting plate for mounting the phosphor wheel and dissipating heat from it. The phosphor wheel enters the interior of the light source box 210 through another mounting port 230, and the heat-conducting plate seals the mounting port 230. The laser light emitted by the phosphor wheel is emitted through the light-transmitting part 212. The heat-conducting plate dissipates the heat from the phosphor wheel, and by directly sealing the mounting port 230 with the heat-conducting plate, the light source box 210 can be made waterproof without the need for an additional waterproof box, effectively reducing costs.

[0047] like Figure 1 In a preferred embodiment of this utility model, the lamp head 100 is further supported by a support arm 400 for rotation and a housing 500 for rotation of the support arm 400. Through the support arm 400 and the housing 500, the lamp head 100 can be rotated around two axes, thereby projecting the light beam in any direction.

[0048] In this embodiment, the rotation axis of the lamp head 100 is perpendicular to the rotation axis of the support arm 400, and both sides of the lamp head 100 are pivotally connected to the support arm 400 via pivot shafts.

[0049] In a preferred embodiment of this utility model, there are two connectors 213, respectively located on both sides of the light source near the pivot joint between the lamp head 100 and the support arm 400. The power supply and signal lines of the lamp head 100 generally pass through the pivot joint between the lamp head 100 and the support arm 400. Therefore, placing the connectors 213 on both sides of the light source near the pivot joint between the lamp head 100 and the support arm 400 facilitates connection and shortens the wiring harness length.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
