Description

Technical Field

[0001] The present invention relates to the technical field of lighting lamps, and more particularly to an integrated lamp assembly suitable for a handheld lighting lamp. Background Art

[0002] Handheld lighting lamps, such as flashlights, as a common portable lighting tool, have a wide range of applications in many scenarios such as daily life, outdoor activities, and emergency rescue. With the continuous improvement of people's requirements for lighting effects, the power of handheld lighting lamps has gradually increased. Especially with the widespread application of high-brightness LED lamp beads, the heat generated by the lamp assembly during operation has increased significantly.

[0003] In the prior art, for example, patent CN220321235U discloses a flashlight, which includes a condenser cup, a substrate, a lamp bead, a centering fixing member, a lens, a waterproof ring, a head pressing ring, and a lamp holder. Among them, the substrate, the lamp bead, and the centering fixing member are combined into a hidden light-sensing structure. The centering fixing member is fitted and installed with the substrate, and the lamp bead is installed between the centering fixing member and the substrate; the middle part of the centering fixing member has a notch through which the light emitted by the lamp bead passes. The condenser cup is a horn-shaped with an open tip, and the inner side of its cup wall is reflective. The condenser cup is arranged in front of the hidden light-sensing structure and the tip faces the centering fixing member. The notch and the through hole of the centering fixing member are both within the range of the opening of the tip of the condenser cup in the axial direction of the flashlight. Its main concern is the light-sensing structure of the flashlight, and the automatic adjustment of the brightness of the flashlight is realized through the hidden light-sensing structure.

[0004] For another example, patent CN118998709A discloses that a lighting module includes a high-beam lamp group and a low-beam lamp group. The high-beam lamp group is located at one end of the main body along the second direction (Y direction). The high-beam lamp group can use high-power LED lamp beads; a high-beam lens is covered on the high-beam lamp group. An installation hole is provided in the central area of the low-beam lamp group, and the high-beam lamp group is installed at the installation hole; correspondingly, the high-beam lens is also arranged in the central area of the low-beam lens.

[0005] The above two patents do not mention the heat dissipation problem of the lamp assembly, and there is no clear measure for how to effectively dissipate the heat generated when the high-power lamp beads work. This may cause the lamp assembly to overheat after long-term high-brightness operation, thereby affecting the overall performance and service life of the flashlight.

[0006] Patent CN116838999A discloses a waterproof flashlight, which mainly relies on the cooperation of a heat sink and a fan to achieve heat dissipation. However, this heat dissipation method may still not be ideal enough during the long-term operation of high-power lamp beads, and it is easy to cause the temperature of the lamp assembly to be too high, affecting the service life and lighting effect of the lamp beads.

[0007] The flashlight lamp components in the prior art have certain deficiencies in heat dissipation. Especially when high-power lamp beads work for a long time, the problem of poor heat dissipation is more prominent. This will not only affect the service life of the lamp beads, but may also cause the flashlight to malfunction, unable to meet the user's requirements for high performance and high reliability of the flashlight in different scenarios.

[0043] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc. is the orientation or positional relationship based on the habitual placement orientation of the product of the present invention during use.

[0044] As Figures 1-4 shown, the integrated lamp assembly provided in this embodiment includes an integrally formed heat dissipation base 1, a horn-shaped condenser cup 2, an LED lamp bead component 3, an LED ring-shaped lamp board 4, and a ring-shaped fastener 5. The structure of the heat dissipation base 1 is as Figure 1 shown, including a base 12 provided with a receiving groove 11, an extension part 13 connected to the rear side of the base 12, and an annular part 14 surrounding the opening of the receiving groove 11. A plurality of spaced first heat dissipation fins 15 are provided on the outer periphery of the base 12, and a plurality of spaced second heat dissipation fins 16 are provided on the outer periphery of the extension part 13. The first heat dissipation fins 15 are connected to the rear side surface of the annular part 14, and the second heat dissipation fins 16 are connected to the rear end surface of the base 12.

[0045] As Figures 1-5As shown, the inner diameter of the receiving groove 11 gradually decreases from front to back. The bottom of the receiving groove 11 provides a stable mounting position with good heat dissipation performance for the LED lamp bead component 3. The LED lamp bead component 3 abuts against the bottom of the receiving groove 11, and the LED lamp bead component 3 dissipates heat through the conduction of the bottom. The receiving groove 11 itself also provides accommodation and support for the condenser cup 2. The condenser cup 2 is arranged in the receiving groove 11 with the small-diameter open end facing backward. The lamp beads of the LED lamp bead component 3 are located inside the small-diameter open end, and the small-diameter open end 21 of the condenser cup 2 is in close fit with the lamp beads of the LED lamp bead component 3.

[0046] As Figures 1-2 As shown in Figures 5 - 7, the LED ring-shaped lamp board 4 abuts against the annular plane 143 on the front side of the annular portion 14. The heat of the LED ring-shaped lamp board 4 is dissipated through the conduction of the annular portion 14. The base 12 or the annular portion 14 is provided with a first snap portion 17. The ring-shaped fastener 5 includes a pressure ring 51 and a plurality of elastic snap petals 52. The elastic snap petals 52 are provided with a second snap portion 53 that cooperates with the first snap portion 17. The pressure ring 51 presses on the outside of the LED ring-shaped lamp board 4, and the elastic snap petals 52 extend into the receiving groove 11 and are snapped with the first snap portion 17. Through the ring-shaped fastener 5, the heat dissipation seat 1, the horn-shaped condenser cup 2, the LED lamp bead component 3, and the LED ring-shaped lamp board 4 are tightly pressed together, realizing the rapid assembly and disassembly of the entire component and improving the production efficiency.

[0047] The cooperation between the LED lamp bead component 3 and the condenser cup 2 realizes the high beam irradiation, and the LED ring-shaped lamp board 4 realizes the low beam irradiation. And this structural design enables the heat dissipation seat 1 to form a multi-stage heat dissipation structure in the front-rear direction, effectively improving the heat dissipation performance and extending the service life of the lamp. In particular, the first heat dissipation fins 15 mainly provide an outward heat dissipation channel for the base 12 and the annular portion 14, and play a supporting role for the annular portion, enhancing the structural rigidity, and are also more conducive to die-casting molding through the connection characteristics between components. The extension portion and the second heat dissipation fins on the extension portion provide an enhanced heat dissipation channel for the bottom of the receiving groove 11, thus being more conducive to the multi-directional and multi-dimensional heat dissipation of the LED lamp bead component 3.

[0048] As Figures 3-4 As shown, the large-diameter open end 22 of the condenser cup 2 is provided with an annular flange 202. The notch of the receiving groove 11 is provided with an annular groove 146 recessed from the annular plane 143. The annular flange 202 is placed on the annular groove 146 and the front surface is flush with the annular plane 143.

[0049] The specific structures of the first snap portion 17 and the second snap portion 53 are as Figure 4 、 5As shown in FIGS. 6 and 7, a notch 141 matching the elastic buckle flap 52 is provided on the inner ring of the annular portion 14. A convex block 142 is provided on the rear side of the annular portion 14, which is located below the notch 141 and protrudes backward. The rear end face of the convex block 142 forms a first buckle portion 17. The end of the elastic buckle flap 52 is provided with a tongue 152 protruding outward, and the front end face of the tongue 152 forms a second buckle portion 53.

[0050] The central hole of the LED ring light board 4 is larger than the notch of the receiving groove 11 and is provided with a corresponding avoidance space, which enables the pressing ring 51 of the ring fastener 5 to press the annular convex edge 202 of the condenser cup 2 while pressing the LED ring light board 4. At the same time, the elastic buckle flap 52 can extend into the notch 141 from front to back to realize the clamping of the tongue 152 and the convex block 142, thereby clamping the heat dissipation base, the condenser cup 2, and the LED ring light board 4. This structural design enables the elastic buckle flap 52 of the ring fastener 5 to be stably buckled with the first buckle portion 17, ensuring the structural stability of the entire assembly.

[0051] Preferably, as Figure 4 shown, a plurality of concave holes 111 matching the LED lamp bead components 3 are provided on the bottom surface of the receiving groove 11. After the convex points of the LED lamp bead components 3 are matched with the concave holes 111, they are positioned and tightly pressed by the condenser cup 2 to achieve assembly, thus eliminating other complex installation methods and making it more convenient for the disassembly, installation, and maintenance of the integrated lamp assembly.

[0052] As Figures 4-6 shown, a plurality of heat dissipation grooves 110 penetrating the receiving groove 11 are provided on the outer periphery of the base portion 12. Connection ribs 19 are formed between adjacent heat dissipation grooves 110, and the first heat dissipation fins 15 are provided on the connection ribs 19. This design further optimizes the heat dissipation performance, enabling heat to be quickly dissipated through the heat dissipation grooves 110. At the same time, this heat dissipation groove also provides a threading channel for line connection, which is more conducive to the line connection between the integrated lamp assembly and the lamp body.

[0053] As Figures 4-6 shown, a plurality of spaced third heat dissipation fins 18 are provided on the rear side of the annular portion 14 adjacent to the heat dissipation grooves 110 to further improve the heat dissipation efficiency while increasing the strength of the annular portion 14. Preferably, the rear end of the third heat dissipation fin 18 does not exceed half of the length of the heat dissipation groove 110.

[0054] It should be noted that the first heat dissipation fins 15, the second heat dissipation fins 16, and the third heat dissipation fins 18 all radiate along the diameter direction of the heat dissipation base.

[0055] As Figure 1 、 5As shown in FIGS. 6, the rear end of the second heat dissipation fin 16 extends to the rear end face of the extension part 13, and the outer diameter of the contour enclosed by the second heat dissipation fin 16 is less than or equal to the rear end diameter of the base 12, so as to expand the heat dissipation surface while integrating the volume and weight of the integrated lamp assembly, and avoid the interference of the heat dissipation performance of the first heat dissipation fin 15 and the second heat dissipation fin 16.

[0056] As Figure 1 shown, the outer contour of the first heat dissipation fin 15 expands to form a support heat dissipation part 161 near the annular part 14. This design not only improves the structural strength of the first heat dissipation fin 15, but also further optimizes the heat dissipation performance. Preferably, the first heat dissipation fin 15 is provided with a thickened strengthening part extending in the front-rear direction.

[0057] As Figure 2 、 4 As shown in FIGS. 5, the front side of the annular part 14 is provided with positioning protrusions 144, and the outer edge of the LED annular lamp board 4 is provided with positioning notches 41. There are two pairs of the positioning protrusions 144 and the positioning notches 41, which are located on both sides of the same diameter of the lamp assembly. This design enables the LED annular lamp board 4 to be quickly positioned during installation, improving the assembly efficiency. The positioning protrusions 144 and the positioning notches 41 are closely matched to ensure the stable installation of the LED annular lamp board 4.

[0058] In addition, as Figure 2 shown, the annular part 14 is also provided with a plurality of inwardly concave wire passing openings 145 to facilitate the connection of the circuits of the LED annular lamp board 4.

The description of the above embodiments is only used to help understand the present invention and its core idea.
