Description

Technical Field

[0001] The utility model belongs to the field of lamps, and in particular is an LED floodlight with high-efficiency heat dissipation performance. Background Art

[0002] LED floodlight is a highly efficient lighting device that uses light-emitting diodes (LEDs) as light sources to project light onto specific areas or objects. This type of lamp is usually used for outdoor lighting, including but not limited to landscape lighting, factory lighting, garden lighting, and media lighting.

[0003] This kind of floodlight has two power supply methods, one is direct power supply through wires; the other is built-in batteries that can be charged. Regardless of the power supply method, it will always generate heat when working. Although there are many heat dissipation holes on the surface of its shell for heat dissipation, this heat dissipation is mainly based on its own self-heating, and its heat dissipation effect is far from ideal.

[0006] Furthermore, vertical slide grooves are symmetrically provided on both sides of the inner wall of the installation box at the position of the notch, and the top of the slide groove is communicated with the top of the installation box; at the same time, both sides of the connecting plate are connected to sliders slidably connected to the slide grooves.

[0007] Furthermore, both sides of the lamp body are connected to horizontal connecting shafts, and the connecting shafts are rotatably connected to the corresponding vertical plates through bearings; in addition, a positioning mechanism is also provided on the bracket to fix the connecting shaft after it rotates.

[0008] Furthermore, the positioning mechanism includes a cylindrical head arranged outside one of the vertical plates, the middle of the inner side of the cylindrical head is connected to a horizontal locking column, and the inner edge is connected to an annular locking ring; in addition, a locking hole for engaging with the locking column is opened on the outer side of one of the connecting shafts, and an annular groove for engaging with the locking ring is opened on the outer side of the vertical plate corresponding to the connecting shaft.

[0009] Furthermore, both the engaging column and the engaging ring are elastic, and the diameter of the engaging column is slightly larger than the diameter of the engaging hole, and the thickness of the engaging ring is slightly larger than the width of the annular groove.

[0010] Furthermore, the outer side of the connecting shaft without the engaging hole can be connected to a convex head located outside the corresponding vertical plate, and the structure of the convex head is the same as that of the cylindrical head to form a symmetrical structure.

[0011] Technical effect: In the utility model, the fan on the connecting plate can be used to dissipate heat from the back of the lamp body; at the same time, since the battery does not exceed the bottom of the notch, the fan can also dissipate heat from the battery in the installation box, killing two birds with one stone. In addition, since the connecting plate can be turned over, the fan can change the wind direction, that is, according to actual needs, it can be selected whether the fan draws cold air from the outside into the installation box for heat dissipation, or draws hot air in the installation box and discharges it to the outside for heat dissipation.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0019] The LED floodlight with high efficiency heat dissipation performance provided in this embodiment is as follows: Figure 1-4 As shown, it includes a main component and an improved component, wherein:

[0020] The main component includes a U-shaped bracket 1 composed of a horizontal plate and two vertical plates and a lamp body 2 located on the bracket 1. The back of the lamp body 2 is connected to a mounting box 3. The back of the mounting box 3 has a notch near the top, and a battery 4 is placed inside the notch, the top of which does not exceed the bottom of the notch. The specific structure is as follows: Figure 3 shown.

[0021] The improved structure includes heat dissipation grooves 5 provided at both the top and bottom of the installation box 3; in addition, a connecting plate 6 is provided at the position of the notch, and two fans 7 are symmetrically provided on the connecting plate 6, so that the fan 7 on the connecting plate 6 can be used to dissipate heat from the back of the lamp body 2; at the same time, since the storage battery 4 does not exceed the bottom of the notch, the fan 7 can also dissipate heat from the storage battery 4 in the installation box 3. In addition, the connecting plate 6 can be turned over, because vertical slide grooves 8 are symmetrically provided on both sides of the inner wall of the installation box 3 at the position of the notch, and the top of the slide groove 8 is connected to the top of the installation box 3; at the same time, both sides of the connecting plate 6 are connected to sliders 9 slidably connected to the slide groove 8. In this way, after the connecting plate 6 is slid out, the fan 7 can be turned over, so that the fan 7 can not only absorb the cold air from the outside and blow it into the installation box 3 for heat dissipation, but also absorb the hot air in the installation box 3 and discharge it to the outside for heat dissipation.

[0022] In addition to the above, if Figure 4 As shown, a transverse connecting shaft 10 is connected to both sides of the lamp body 2, and the connecting shaft 10 is rotatably connected to the corresponding vertical plate through a bearing; in addition, a positioning mechanism 11 is also provided on the bracket 1 to fix the connecting shaft 10 after it rotates, and the positioning mechanism 11 includes a cylindrical head 1101 provided outside one of the vertical plates, and the inner middle of the cylindrical head 1101 is connected to a transverse clamping column 1102, and the inner edge is connected to an annular clamping ring 1103; in addition, a clamping hole 1104 for clamping with the clamping column 1102 is provided on the outer side of one of the connecting shafts 10, and a ring groove 1105 for clamping with the clamping ring 1103 is provided on the outer side of the vertical plate corresponding to the connecting shaft 10. The purpose of this arrangement is to make the irradiation angle of the lamp body 2 adjustable.

[0023] It is worth mentioning that the above-mentioned locking column 1102 and locking ring 1103 are both elastic, and in order to better lock, the diameter of the locking column 1102 is slightly larger than the diameter of the locking hole 1104, and the thickness of the locking ring 1103 is slightly larger than the width of the annular groove 1105.

[0024] Finally, in order to make the structure symmetrical and beautiful, the outer side of the connecting shaft 10 without the engaging hole 1104 can be connected to a convex head located outside the corresponding vertical plate. The structure of the convex head is the same as that of the cylindrical head 1101 to form a symmetrical structure.

[0025] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
