Detailed Implementation

[0033] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples:

[0034] This utility model discloses a modular LED floodlight, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 10 As shown, the device includes a heat sink 1 and a light source module 2, the light source module 2 being disposed on the front side of the heat sink 1, and further includes:

[0035] The connecting component 3 is connected to the outside of several heat dissipation fins 12 on the back of the heat sink 1 and covers the wiring port 11 located at one end of the heat sink 1.

[0036] The bracket assembly 4 is connected to the outside of the heat sink 1 through the connecting assembly 3. The bracket assembly 4 includes a rotating part 42 connected to the connecting assembly 3. The heat sink 1 is detachably connected to the rotating part 42 through the connecting assembly 3. The joint rotation of the rotating part 42 and the heat sink 1 changes the light illumination direction of the light source module 2.

[0037] The power module 5 is detachably connected to the back of the heat sink 1 via the connecting component 3.

[0038] It should be noted that: the wiring port 11 allows the wire to be introduced from one end of the heat sink 1 to the location of the light source module 2, and is covered by the connecting component 3 so that the wire is not exposed; the rotating part 42 allows the heat sink 1 to be rotated and connected to the bracket assembly 4, so that the illumination direction of the light source module 2 can be changed by rotating the heat sink 1 when the lamp is in use, thereby adjusting the illumination direction of the lamp; the light source, bracket 41 and power supply 52 of this floodlight are all modularly designed, and are detachably connected to the heat sink 1 by the connecting component 3. Moreover, the modular power supply 52 has different structures, so that the power supply 52 can meet the usage requirements of the floodlight in different scenarios. The connecting component 3 is equipped with different structures to match the different structures of the power supply 52, simplifying the maintenance process. At the same time, the connecting component 3 cleverly hides the lamp wiring inside the lamp, resulting in a simple appearance with no exposed cables.

[0039] As one embodiment of this utility model, such as Figures 1-4 As shown, the connecting assembly 3 includes a first connecting plate 31 with a C-shaped cross-section; the power module 5 includes a power box 51 and a power supply 52; the heat dissipation fins 12 on both sides of the back of the heat sink 1 are provided with at least one first mating hole 121; one end of the first connecting plate 31 is provided with at least one second mating hole 311; one end of the first connecting plate 31 is fixedly connected to the heat dissipation fins 12 by fasteners connected to the corresponding first and second mating holes 121 and 311; one end of the power box 51 is provided with at least one third mating hole 511 on both sides of one end face; the other end of the first connecting plate 31 is provided with at least one fourth mating hole 312; the other end of the first connecting plate 31 is fixedly connected to the power box 51 by fasteners connected to the corresponding third and fourth mating holes 311 and 312; and the power supply 52 is disposed inside the power box 51.

[0040] The first connecting plate 31 is connected to the power supply box 51 and the heat sink 1 by fasteners at both ends, so that the power supply box 51 can be detachably connected to the heat sink 1 and can be removed from the heat sink 1 when the power module 5 is replaced; while the power supply 52 is set in the power supply box 51 and can be protected by the power supply box 51 to avoid external factors affecting the normal operation of the power supply 52.

[0041] As a further implementation of the above embodiments, such as Figure 2 and Figure 5As shown, the power supply box 51 includes a first housing 512 and a second housing 513. The first housing 512 and the second housing 513 are connected by at least one hinge at one end of each housing. The opening and closing sides of the first housing 512 and the second housing 513 are connected by a detachable fastener. Both the surface of the first housing 512 and the second housing 513 are provided with wire terminals 515.

[0042] When inspecting the power supply 52 inside the power box 51, the fixing parts on the opening and closing sides of the first housing 512 and the second housing 513 can be removed to open the power box 51. The wiring end 515 allows the wire to be introduced into the power box 51 from the first housing 512 and then led out through the second housing 513. This enables the power supply 52 to obtain and output power while keeping the connection between the wire and the power supply 52 from being exposed, making the use of the floodlight safer.

[0043] As one embodiment of this utility model, such as Figures 6-9 As shown, the connecting assembly 3 includes a second connecting plate 32 with a Z-shaped cross-section, the power module 5 is a power supply 52, and the heat dissipation fins 12 on both the left and right sides of the back of the heat sink 1 are provided with at least one fifth mating hole 122. One end of the second connecting plate 32 is provided with at least one sixth mating hole 321. One end of the second connecting plate 32 is fixedly connected to the heat dissipation fins 12 by fasteners connected to the corresponding fifth mating holes 122 and sixth mating holes 321. The power supply 52 is provided with protruding plates 521 on both the left and right sides, and each protruding plate 521 has at least one seventh mating hole 5211. The other end of the second connecting plate 32 is provided with at least one eighth mating hole 322. The other end of the second connecting plate 32 is fixedly connected to the power supply 52 by fasteners connected to the corresponding seventh mating holes 5211 and eighth mating holes 322.

[0044] The difference between this embodiment and the previous embodiment is that the power supply 52 in this embodiment is set up in a form that is directly exposed on the outside of the lamp. On the one hand, it is convenient to observe the power supply 52 and the wires connected to the power supply 52 during maintenance. On the other hand, the lamp will be lighter and smaller in size after the power supply box 51 is reduced, making the requirements for fixing the lamp lower when it is set at a high place.

[0045] It needs to be further explained that, such as Figure 10 and Figure 11As shown, the connecting component 3 includes a third connecting plate 33. One end of the third connecting plate 33 is located outside the outermost heat dissipation fins 12 on the left and right sides of the radiator 1, and covers the outermost heat dissipation fins 12 on the left and right sides of the radiator 1. The other end of the third connecting plate 33 is located outside the left and right sides of the radiator 1, and covers the left and right sides of the radiator 1.

[0046] The left and right sides of the heat sink 1 are detachably connected to the third connecting plate 33, which can cover the left and right sides of the heat sink 1, thereby covering the location of the wiring port 11.

[0047] Specifically, such as Figure 10 and Figure 11 As shown, the heat dissipation fins 12 on both the left and right sides of the back of the heat sink 1 are provided with at least one ninth mating hole 123 in the middle, and the walls at both ends of the heat sink 1 are provided with at least one tenth mating hole 13. The third connecting plate 33 covers the middle wall of the heat dissipation fins 12 on both the left and right sides and the outer wall of both the left and right ends, and is provided with at least one eleventh mating hole 331. The third connecting plate 33 inserts a fixing member into the corresponding ninth mating hole 123 and eleventh mating hole 331, or inserts a fixing member into the corresponding tenth mating hole 13 and eleventh mating hole 331, so as to realize the connection with the heat sink 1. The wall of the third connecting plate 33 near the tenth mating hole 13 is connected to the rotating part 42.

[0048] The third connecting plate 33 allows the heat sink 1 to be detachably connected to the bracket assembly 4, so that the heat sink 1 can be removed during the maintenance of the lamp for easy replacement.

[0049] Specifically, such as Figure 10 As shown, a third connecting plate 33 near the wiring port 11 is provided with a wire passage groove 332.

[0050] The cable tray 332 allows the power module 5's wires to pass through the third connecting plate 33 and into the wiring port 11, thereby providing power to the light source module 2. The wires are positioned between the power supply 52 and the heat sink 1, and the wiring is arranged reasonably without being exposed outside the overall lamp.

[0051] Specifically, such as Figure 10 and Figure 11As shown in the figure, the bracket assembly 4 also includes a bracket 41, and the rotating part 42 includes two covers 421 and a shaft connector 43. One of the covers 421 is fixedly connected to both ends of the bracket 41, and the other cover 421 is located outside the third connecting plate 33 at both ends of the radiator 1. The two covers 421 are connected by a shaft connector 43 that passes through their middle parts, the ends of the bracket 41 and the third connecting plate 33. The walls of both covers 421 near their sides are provided with a ring of meshing teeth 422.

[0052] The heat sink 1 can rotate around the axis of the shaft connector 43 to adjust the illumination angle of the light source module 2. The meshing teeth 422 on the two covers 421 can rotate relative to each other without loosening, so as to ensure that the position of the heat sink 1 will not move when not operated by humans and that the light output position of the lamp is stable.

[0053] More specifically, such as Figure 11 As shown, a scale 423 is provided on the surface of the cover 421 located at the end of the shaft connector 43 away from the heat sink 1; when rotating the heat sink 1, the current illumination angle of the light source module 2 can be understood by observing the value on the scale 423, making it more convenient to adjust the illumination angle of the light source module 2.

[0054] It needs to be further explained that, such as Figure 1 , Figure 12 and Figure 13 As shown, the light source module 2 includes a PCB 21, LED beads 22, and a lens 23. The PCB 21 is fixedly connected to the mating groove 14 on the front of the heat sink 1 by a fastener. The LED beads 22 are embedded on the front of the PCB 21. The lens 23 is fixedly connected to the mating groove 14 on the outside of the PCB 21 by a fastener. The inner surface of the lens 23 has a plurality of reflectors 231 located on the outside of the LED beads 22 integrally formed.

[0055] The light source is covered by a full-panel lens 23, which ensures uniform light distribution and avoids glare or excessive brightness in certain areas. The power of the lamp can be adjusted to 150W / 300W / 450W by adjusting the LED beads 22, making it easy to flexibly adapt to different power requirements.

[0056] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
