Description

Technical Field

[0001] The present invention relates to the field of lighting devices, and in particular to a modular LED searchlight. Background Art

[0002] A searchlight is a large lighting device with a powerful light source and a concave mirror that can focus light in a specific direction. It is used for long-distance lighting and searching.

[0003] In order to meet the requirements of light intensity and illumination distance, existing searchlights need to be equipped with multiple light sources, and the design of modular light sources has gradually been integrated into the manufacturing of searchlights.

[0004] A prior art document (publication number: CN104864345A, patent name: An LED searchlight and its housing, publication date: August 26, 2015) discloses an LED searchlight. The searchlight adopts a structure of multiple LED light source modules. These LED light source modules are arranged in a frame. When the LED light source module needs to be maintained, tools are needed to remove the lamp components outside the LED light source module and the connecting components that fix the LED light source module in order to remove the LED light source module. Due to the large size of the searchlight, the time required to dismantle the lamp components outside the light source module is longer than that of ordinary lamps, making the lamp maintenance more difficult.

[0005] Moreover, the rear cover of the searchlight in the above-mentioned document is equipped with a heat dissipation channel for dissipating heat separately for the LED light source module, but the direction of heat conduction is usually upward, and heat energy is easily accumulated in the top of the shell. The heat energy cannot be transferred to a place far away from the light source, which easily causes the light source to overheat and burn out.

[0006] Therefore, it is necessary to improve the LED searchlight with a modular light source structure. Summary of the Invention

[0008] To achieve the above object, the present invention is implemented through the following technical solutions:

[0041] The light source of the searchlight adopts a modular design. When the LED 9 on the searchlight requires maintenance, the light source module 6 containing the LED 9 to be replaced can be disassembled. This allows maintenance to be performed without disassembling the entire light source and outer components of the searchlight, simplifying lamp maintenance. The light source module 6 is secured to the lamp holder 4 by a lower locking mechanism 13 and an upper locking mechanism 51. This modular light source can be secured without any tools, making light source replacement on the lamp faster. The heat pipe 10 guides heat generated by the lamp during operation to the bottom of the light source, preventing heat from accumulating near the light source and causing it to overheat and burn out. The heat is then transferred to the multiple heat dissipation fins 11 below the light source, thereby quickly dissipating the heat outside the lamp. During installation of the light source module 6 to the lamp holder 4, the sub-conductive terminal 52 is inserted into the female conductive terminal 14 to connect the current, thereby improving the safety of the light source module 6 during installation.

[0042] The heat dissipating fins 11 are provided with a plurality of first matching holes 15, and the heat conducting pipe 10 is n-shaped. The heat dissipating fins 11 are fitted in the vertical part of the heat conducting pipe 10 through the first matching holes 15. A plurality of connecting plates 16 are provided circumferentially along the edge of the heat dissipating fins 11. A first clip 17 is provided in the middle of the bottom end of the connecting plate 16, and a second clip 18 is provided on both sides of the bottom end of the connecting plate 16. A first card interface 19 is provided in the middle of the top end of the connecting plate 16.

[0043] Among them, two adjacent heat dissipation fins 11 in the vertical direction are connected by the snap-fitting of the first clip 17 and the second clip 18, thereby forming a stacked structure, and the number of heat dissipation fins 11 can be adjusted to meet the heat dissipation requirements of light sources with different powers.

[0044] The lower locking mechanism 13 includes a fixed seat 20, a first rotating shaft 21, a fastener 22 and a clamping seat 23. A plurality of fixed seats 20 are provided on the circumferential surface of the connecting frame 2 outside the lower through hole 12. The first rotating shaft 21 is matched with the top of all the fixed seats 20 in the same straight line direction through a bearing. The two sides of the bottom end of the fastener 22 are fixed to the two ends of the first rotating shaft 21. A wedge-shaped clamping seat 23 is provided on the outer side of the top of the fastener 22. The clamping seat 23 is provided with a second clamping interface 24 for matching the first buckle 17. The fastener 2 2. Both sides of the top are provided with third clips 25 for clamping the second clip 18. The ends of the two adjacent first rotating shafts 21 are provided with bevel gears 26. The bevel gears 26 on the two first rotating shafts 21 are meshed with each other. One end of one of the first rotating shafts 21 is provided with a torsion block 27. The top of the clamping seat 23 is provided with a first inclined surface 28 that gradually tilts outward from high to low. The upper and lower ends of the end of the second clip 18 are provided with first rounded corners 29. The upper and lower ends of the end of the third clip 25 are provided with second rounded corners 30.

[0045] Among them, when the light source module 6 is inserted into the lamp holder 4 from top to bottom, the first clip 17 of the heat dissipation fin 11 at the bottom end of the light source module 6 is guided by the first inclined surface 28 to enter the second clip interface 24, so that the first clip 17 is clipped into the clip seat 23; at the same time, the second clip 18 is guided between the first fillet 29 and the second fillet 30 to enter and be fixed under the third clip 25, thereby achieving the fixation of the bottom end of the light source module 6; when the light source module 6 needs to be disassembled, the first rotating shaft 21 is rotated by twisting the twisting block 27. When the first rotating shaft 21 rotates, the fastener 22 swings in the direction away from the first clip 17 and the second clip 18, so that the first clip 17 is moved out of the clip seat 23, and the second clip 18 is away from the third clip 25, thereby releasing the fixing effect of the lower locking mechanism 13 on the bottom end of the source module.

[0046] The upper locking mechanism 51 includes a swing plate 31, a connecting seat 32 and a positioning strip 33. The top surface of the lamp holder 4 outside the upper through hole 5 is provided with a plurality of fixing plates 34. The outer side of the female conductive terminal 14 is fixedly connected with the fixing plate 34. The top of the fixing plate 34 is fixed to the top surface of the lamp holder 4 outside the upper through hole 5. The connecting seat 32 is provided on the outer wall of the fixing plate 34. One end of the swing plate 31 is provided with a matching groove 35. The bottom end of the connecting seat 32 is located in the matching groove 35 and is passed toward the matching groove 35. The second rotating shaft is inserted to make the swing plate 31 movably connected to the connecting base 32. The second rotating shaft outer sleeves on both sides of the connecting base 32 are provided with torsion springs 36. The positioning strip 33 is fixed to the surface of the swing plate 31 outside the matching groove 35. The edge of the lamp holder 7 is provided with a plurality of ejector pins 37.

The middle part of the ejector pin 37 is provided with an annular groove 39. The top end of the positioning strip 33 is provided with a clamping block 40 that fits in the annular groove 39.

[0047] Among them, when the light source module 6 is inserted into the lamp holder 4 from top to bottom, the ejector pin 37 presses one end of the swing plate 31 downward, and one end of the swing plate 31 moves downward, so that the positioning bar 33 swings toward the ejector pin 37, and the clamping block 40 swings toward the annular slot 39 and is clamped in the annular slot 39, thereby forming a structure for fixing the top of the light source module 6.

[0048] The wall surface of the ejector pin 37 above the annular groove 39 is a ring-shaped second inclined surface 41, and the second inclined surface 41 is an inclined surface that gradually tilts inward from high to low. The end of the clamping block 40 is a third clamping interface 42, and the cross-section of the third clamping interface 42 in the horizontal direction is C-shaped. The clamping block 40 outside the top end of the third clamping interface 42 is provided with an arc-shaped third inclined surface 43, and the third inclined surface 43 is an inclined surface that gradually tilts inward from high to low.

[0049] In the process of the ejector pin 37 moving downward, the beveling effect of the second inclined surface 41 and the third inclined surface 43 can enable the third engaging interface 42 of the engaging block 40 to be engaged with the annular engaging groove 39 more smoothly.

[0050] The edge of the lamp holder 7 is provided with several threaded holes 44, the outer wall of the ejector pin 37 is provided with threads, and the ejector pin 37 is fitted into the threaded hole 44 through threads. The outer wall of the ejector pin 37 is provided with a through groove 45, and the through groove 45 extends from the annular groove 39 to the bottom surface of the ejector pin 37. The cross-section of the groove in the horizontal direction is C-shaped.

[0051] When the light source module 6 needs to be disassembled, the locking block 40 is moved to the through groove 45 by rotating the ejector pin 37. After the lower locking mechanism 13 releases the fixing effect on the bottom end of the light source module 6, the entire light source module 6 can be removed from the lamp holder 4 by lifting the light source module 6 upward.

[0052] The distribution box is provided with a plurality of first waterproof joints 46 , the bottom end of the female conductive terminal 14 is provided with a second waterproof joint 47 , and the edge of the top end of the female conductive terminal 14 is provided with a sealing ring 48 .

[0053] Among them, the first waterproof joint 46 and the second waterproof joint 47 can improve the safety of the wires between the distribution box and the mother conductive terminal 14, and the sealing ring 48 can increase the waterproof performance of the connection between the sub-conductive terminal 52 and the mother conductive terminal 14, thereby improving the safety of the connection between the sub-conductive terminal 52 and the mother conductive terminal 14.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
