Description

Technical Field

[0001] The present invention relates to the field of lighting, and particularly to a high-power fixed LED lamp. Background Art

[0002] In industrial lighting, especially in the offshore industry, due to the requirements of the working environment, lights are needed for floodlighting and illumination. High-power lights are required to provide sufficient brightness, and the lights need to operate continuously for a long time.

[0003] Long-term and high-intensity lighting tasks are likely to cause damage to the lamp itself. In particular, the lamp board inside the lamp is prone to heat generation, and other electronic components inside the lamp operate in a high-temperature environment, resulting in a shortened service life and prone to failures. Further, the heat generated at the lamp board is easily transmitted to the power supply cavity and wiring cavity of the lamp through the wiring holes, which is likely to cause failures of accessories such as the power supply and wire row. Summary of the Invention

[0004] An object of the present invention is to overcome the deficiencies in the prior art and provide a high-power fixed LED lamp, which solves the problem that the heat generated by the lamp board during long-term operation affects the internal electronic components of the lamp body, and reduces the occurrence probability of related failures caused by heat.

[0005] The object of the present invention is achieved by the following technical solutions:

[0006] A high-power fixed LED lamp, which includes: a lamp head, a bracket, a wire conduit, and a distribution box;

[0007] The lamp head includes a main housing, a lamp board, and a lens. The lamp board and the lens are located on one side of the main housing. On the side of the main housing away from the lamp board, there are columns and a plurality of heat dissipation fins, and each heat dissipation fin extends from the edge of the main housing towards the center position of the main housing;

[0008] The distribution box is arranged on the column, and the wire conduit is arranged between the distribution box and the main housing. The wire conduit is used to connect the inner cavity of the distribution box and the inner cavity of the main housing.

[0010] In one embodiment, the power supply cavity is filled with structural adhesive.

[0011] In one embodiment, the distribution box is provided with a wire connector, and the wire connector is communicated with the wiring cavity.

[0012] In one embodiment, the wire duct includes a pipe body and T-shaped rotating shafts located at both ends of the pipe body. The T-shaped rotating shafts are rotatably arranged on the pipe body. Locking teeth are provided on the T-shaped rotating shafts. Locking holes matching the locking teeth are formed on both the main housing and the distribution box. The locking holes are provided with alternately distributed avoidance portions and blocking portions. Rotating the T-shaped rotating shafts can make the locking teeth face the avoidance portions or the blocking portions. A wire hole is provided on the T-shaped rotating shaft. When fixing the wire duct, two T-shaped rotating shafts need to be rotated, and the rotation directions of the two T-shaped rotating shafts are opposite to stagger the wire holes on them.

[0013] In one embodiment, a flange is provided at the central position of the pipe body. A spring and a movable ring are provided between the flange and the T-shaped rotating shaft.

[0019] 1. The distribution box and the lamp head are of a split design, separating the installation positions of the lamp board, the power supply, and the bus bar, so that the power supply and the bus bar are away from the heat source, improving the safety performance of the lamp.

[0020] 2. The lamp head and the distribution box are connected through a wire duct. Cables are laid through the wire duct to avoid cable exposure. The wire duct protects the cables and prevents cable aging.

[0021] 3.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] Please refer to Figure 1 and Figure 2 , the present invention provides a high-power fixed LED lamp 10, which includes: a lamp head 100, a bracket 200, a wire duct 300 and a distribution box 400.

[0036] Please refer to Figure 2 and Figure 3 , the lamp head 100 includes a main housing 110, a lamp board 120 and a lens 130. The lamp board 120 and the lens 130 are located on one side of the main housing 110. On the side of the main housing 110 away from the lamp board 120, there are provided columns 111 and a plurality of heat dissipation fins 112. Each heat dissipation fin 112 extends from the edge of the main housing 110 towards the center position of the main housing 110;

[0037] The distribution box 400 is arranged on the column 111, and the wire duct 300 is arranged between the distribution box 400 and the main housing 110. The wire duct 300 is used to connect the inner cavity of the distribution box 400 and the inner cavity of the main housing 110.

[0038] The above-mentioned high-power fixed LED lamp 10 has the following beneficial effects:

[0039] 1. The distribution box 400 and the lamp cap 100 are of a split design, thus separating the installation position of the lamp board 120 from the installation positions of the power supply and the wire row, enabling the power supply 411 and the wire row 421 to be away from the heat source, preventing the heat generated during the operation of the lamp board from directly affecting electronic components such as the power supply and the circuit board, thereby reducing the failures caused by the long-term continuous operation of the lamp, and improving the safety performance of the lamp.

[0040] 2. The lamp cap 100 and the distribution box 400 are connected through a wire conduit 300. Since the lamp cap 100 and the distribution box 400 are of a split design and the lamp board in the lamp cap 100 needs to be electrically connected to the distribution box 400 through a cable, the wire conduit 300 is provided to offer a space for laying the cable and to avoid the cable being exposed. The wire conduit 300 protects the cable and prevents the cable from aging.

[0041] 3. The wire conduit 300 and the column 111 cooperate to fix the distribution box 400, leaving a gap between the distribution box 400 and the main housing 110, allowing the heat dissipation fins 112 on the main housing 110 to extend towards the central position of the main housing 110, increasing the coverage area of the heat dissipation fins 112. As shown in, the heat dissipation fins 112 can extend into the part blocked by the distribution box 400, thereby improving the heat dissipation effect of the main housing 110 on the lamp board 120. Figure 2 As shown, the heat dissipation fins 112 can extend into the part blocked by the distribution box 400, thereby improving the heat dissipation effect of the main housing 110 on the lamp board 120.

[0042] It can be understood that by separating the distribution box 400 from the lamp cap 100, the heat generated during the operation of the lamp board 120 can be prevented from directly transferring to the surrounding electronic components such as the power supply 411 and the wire row 421, avoiding failures caused by temperature. In the application, to meet the wiring requirements and avoid the cable being exposed, a wire conduit 300 is configured between the distribution box 400 and the lamp cap 100. While protecting the cable, it also connects the distribution box 400 and the lamp cap 100. In this way, when the lamp operates, the heat generated by the lamp board 120 can enter the distribution box 400 through the wire conduit 300. On the other hand, the wire conduit 300 also serves as a fitting connecting the distribution box 400 and the lamp cap 100. To ensure the safe use of the lamp, especially in the offshore industry, due to the humid environment, the lamp needs to be inspected regularly to detect problems in advance. When a failure occurs, the faulty fitting needs to be replaced. Therefore, how to make the distribution box 400 and the lamp cap 100 easy to disassemble and install is also a problem that needs to be solved.

[0043] Please refer to Figure 4 、 Figure 5 and Figure 6, To solve the above problems, the wire duct 300 includes a duct body 310 and T-shaped rotating shafts 320 located at both ends of the duct body 310. The T-shaped rotating shafts 320 are rotatably arranged on the duct body 310. Locking teeth 321 are provided on the T-shaped rotating shafts 320. Locking holes 20 matching the locking teeth 321 are formed on both the main housing 110 and the distribution box 400. The locking holes 20 are provided with alternately distributed avoidance portions 21 and blocking portions 22. Rotating the T-shaped rotating shafts 320 can make the locking teeth 321 face the avoidance portions 21 or the blocking portions 22;

[0044] Please refer to Figure 7 and Figure 8 , when the locking teeth 321 face the avoidance portions 21, the T-shaped rotating shafts 320 can extend into the locking holes 20. In this state, the T-shaped rotating shafts 320 can slide along the axis of the locking holes 20; when the locking teeth 321 face the blocking portions 22, the blocking portions 22 block the locking teeth 321. In this state, the T-shaped rotating shafts 320 are locked and cannot slide along the axis of the locking holes 20.

[0045] Among them, the avoidance portions 21 and the blocking portions 22 are alternately distributed in the locking holes 20, that is, the T-shaped rotating shafts 320 can switch between the locked or sliding states by rotating at most 180°. And the necessary rotation angle for switching the state of the T-shaped rotating shafts 320 decreases with the increase in the number of configurations of the locking teeth 321, the avoidance portions 21, and the blocking portions 22. For example: when the number of configurations of the locking teeth 321, the avoidance portions 21, and the blocking portions 22 is 2, the cooperation state between the T-shaped rotating shafts 320 and the locking holes 20 is as shown in Figure 7 and Figure 8 . Only by rotating 90° can the locking holes 20 be moved from the blocking portions 22 to the avoidance portions 21, and vice versa. That is, increasing the number of configurations of the locking teeth 321, the avoidance portions 21, and the blocking portions 22 can reduce the rotation angle required for switching the state.

[0046] Wire holes 322 are provided on the T-shaped rotating shafts 320. When fixing the wire duct 300, two T-shaped rotating shafts 320 need to be rotated, and the rotation directions of the two T-shaped rotating shafts 320 are opposite to stagger the wire holes 322 on them. Here, fixing the wire duct 300 means rotating the T-shaped rotating shafts 320 to align the locking teeth 321 with the blocking portions 22. In this application, the wire duct 300 is a component connecting the lamp head 100 and the distribution box 400. One T-shaped rotating shaft 320 is responsible for fixing the main housing 110, and the other T-shaped rotating shaft 320 is responsible for fixing the distribution box 400. When fixing, the rotation directions of these two T-shaped rotating shafts 320 are opposite, so that the wire holes 322 on the two T-shaped rotating shafts 320 are staggered.

[0047] A flange 311 is provided at the center of the tube body 310, a spring 330 and a movable ring 340 are provided between the flange 311 and the T-shaped rotating shaft 320, a stopper 312 is provided at the end of the tube body 310, the outer diameter of the stopper 312 is smaller than the diameter of the locking hole 20, and the movable ring 340 is slidably provided between the flange 311 and the stopper 312, and the spring 330 is used to push the movable ring 340 away from the flange 311 so that the movable ring 340 and the stopper 312 are in contact with each other. Figure 4 Shown above.

[0048] The T-shaped shaft 320 has a heat insulating layer 323 formed therein. The heat insulating layer 323 is filled with a material with poor thermal conductivity. The T-shaped shaft 320 has a hexagonal slot 324. A hexagonal wrench inserted into the hexagonal slot 324 can drive the T-shaped shaft 320 to rotate.

[0049] The assembly process of the wiring tube 300, the lamp holder 100 and the distribution box 400 is as follows:

[0050] When it is necessary to use the wiring tube 300 to connect the distribution box 400 and the lamp holder 100, after inserting the cables on the lamp holder 100 into the wire holes 322 on the two T-shaped shafts 320, one end of the tube body 310 is directed toward the lamp holder 100, and the T-shaped shaft 320 on this end is rotated so that the locking tooth 321 is aligned with the avoidance portion 21 of the locking hole 20 on the lamp holder 100, and force is applied to insert the tube body 310 into the locking hole 20. When the locking tooth 321 passes through the locking hole 20 and enters the lamp, After the cable is inserted into the inner cavity of the head 100, the T-shaped shaft 320 is rotated so that the locking tooth 321 is offset from the avoidance portion 21 and contacts the blocking portion 22, thereby locking the T-shaped shaft 320 and the main shell 110; after the cable is inserted into the distribution box 400, the T-shaped shaft 320 on the other end of the tube body 310 can be sent into the distribution box 400 for locking in the same operation mode. After the locking operation is completed, the matching state of the wiring tube 300, the distribution box 400 and the main shell 110 is as shown in FIG. Figure 5 shown.

[0051] When the distribution box 400 or the lamp holder 100 needs to be disassembled, it is only necessary to rotate the T-shaped shaft 320 corresponding to the target (distribution box 400 or lamp holder 100) so that the locking tooth 321 on the T-shaped shaft 320 moves from the blocking portion 22 to the avoidance portion 21. When the locking tooth 321 and the avoidance portion 21 are unlocked, the distribution box 400 or the lamp holder 100 can be lifted and removed.

[0052] Among them, when the pipe body 310 is inserted into the locking hole 20, the outer wall of the main housing 110 (or the outer wall of the power distribution box 400) will block the movable ring 340, that is, the movable ring 340 will not pass through the locking hole 20 together with the T-shaped rotating shaft 320. Relative sliding occurs between the movable ring 340 and the pipe body 310, causing the spring 330 to compress. The elastic force provided by the spring 330 causes the movable ring 340 to tightly press against the outer wall of the main housing 110 (or the outer wall of the power distribution box 400). In this way, the movable ring 340 and the locking teeth 321 cooperate to form an inner and outer clamping structure to clamp the main housing 110 (or the power distribution box 400). The assembly process only requires applying force to push the pipe body 310 and rotate the T-shaped rotating shaft 320. The assembly process is convenient. After locking, the spring 330 can provide an elastic force to clamp the main housing 110 (or the power distribution box 400), and the structure is reliable. Further, a sealing ring 341 is provided on the end face of the movable ring 340 to provide sealing when the movable ring 340 contacts the main housing 110 or the power distribution box 400, preventing external water vapor from entering the interior of the lamp.

[0053] It should be emphasized that when performing the locking operation, the rotation directions of the two T-shaped rotating shafts 320 are opposite, that is, after the locking operation is completed, the wire holes 322 on the two T-shaped rotating shafts 320 are staggered from each other, increasing the difficulty of the hot air diffusing from the lamp head 100 to the power distribution box 400 in the way of making the wire routing channel tortuous, thereby avoiding the heat generated by the operation of the lamp board 120 from interfering with the normal operation of the electronic components in the power distribution box 400. At the same time, due to the staggering of the wire holes 322, the cables passing through the two will be bent in the pipe body 310, increasing the friction force between the cables and the hole walls of the wire holes 322, increasing the tensile strength of the cables. When the cables are pulled during the maintenance or replacement of components, the welded parts of the cables and the lamp board 120 will not be stressed, preventing the position from being broken and causing the electrical connection between the lamp board 120 and the power supply to be disconnected.

[0054] It can be understood that the location of the failure of the lamp is uncertain. It may be that the lamp board 120 inside the lamp head 100 is damaged, or it may be that other electronic components such as the power supply and control board in the power distribution box 400 are damaged. The same locking structure is adopted at both ends of the wire pipe 300, that is, the clamping structure composed of the T-shaped rotating shaft 320, the spring 330, and the movable ring 340. Maintenance personnel can purposefully remove the faulty parts on the lamp for replacement and repair. After disassembly, it will not affect the components on the other side. The disassembly process only requires rotating the T-shaped rotating shaft 320, and the operation is simple and fast.

[0055] Please refer to Figure 1 , in an embodiment, the bracket 200 is provided with a connecting ear 210, and the connecting ear 210 is rotatably connected to the main housing 110. This enables relative rotation between the bracket 200 and the main housing 110, facilitating the user to adjust the lighting angle.

[0056] Please refer to Figure 3, in one embodiment, a power supply cover 440 is provided on one side of the distribution box 400 away from the main housing 110. The power supply cover 440 can be detached separately, facilitating later maintenance and repair.

[0057] Please refer to Figure 3 , in one embodiment, a power supply cavity 410 and a wiring cavity 420 are provided inside the distribution box 400. A power supply 411 is provided in the power supply cavity 410, and a wire row 421 is provided in the wiring cavity 420. The power supply cavity 410 and the wiring cavity 420 are separated by a partition 450, and the power supply cavity 410 is filled with structural adhesive to protect accessories such as the power supply 411 by means of potting.

[0058] Please refer to Figure 3 , in one embodiment, a wire connector 430 is provided on the distribution box 400. The wire connector 430 is communicated with the wiring cavity 420, and an external cable is docked with the wire row 421 in the wiring cavity 420 through the wire connector 430.

[0059] The above embodiments only represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
