Description

Technical Field

[0001] The utility model relates to the technical field of lamp lighting, in particular to a heat dissipation type floodlight. Background Art

[0002] The existing floodlights on the market are generally divided into aluminum extruded floodlights and die-cast floodlights according to the different heat dissipation mechanisms. The corresponding heat sinks are aluminum extruded heat sinks and die-cast heat sinks. Most of the power supply components are located inside the lamp housing of the floodlight to avoid short-circuit damage to the power supply components due to external water vapor entering.

[0003] However, the power supply component of the floodlight is arranged inside the lamp housing. Although it can improve the working environment of the power supply component and extend the normal working cycle, it will inevitably generate heat during the operation of the floodlight and accumulate in the lamp housing. In addition, the heat generated by the lamp board and light source components in the floodlight causes the heat in the lamp housing to accumulate more. If the heat is not dissipated and conducted out in time, the power supply component and the light source component will be damaged.

[0004] In the prior art, a Chinese utility model patent, authorization announcement number: CN220728173U, discloses a floodlight, including a shell, a light-transmitting cover covering the side of the shell, a light source board arranged inside the shell, a rear cover connected to the side of the shell away from the light-transmitting cover, a power adapter arranged inside the rear cover, and a plurality of notches arranged on the side of the rear cover facing the shell. By arranging the power adapter outside the shell, the heat dissipation efficiency can be effectively improved.

[0005] In the above technical solution, the power supply unit is located between the shell and the rear cover, and is specifically assembled on the inner surface of the rear cover. By designing multiple notches on the side of the rear cover facing the shell and the heat dissipation ribs, the heat in the rear cover and the shell is dissipated through the notches. However, this heat dissipation structure has, on the one hand, a poor heat dissipation effect and insufficient conduction heat dissipation. On the other hand, the heat dissipation structure is complicated to assemble and is not conducive to mass production.

[0006] Therefore, it is necessary to provide a floodlight that overcomes the above problems. Utility Model Content

A power slot is provided on the third heat sink, and a power supply unit is installed in the power slot. A part of the power supply unit is buried in the power slot, and the other part of the power supply unit is exposed outside the power slot. Since the power supply unit is exposed on the third heat sink on the lamp housing, a part of the heat on the power supply unit can be directly dissipated into the air, and the remaining part of the heat is conducted into the air through the third heat sink, thereby accelerating the overall heat dissipation efficiency of the floodlight and saving the internal use space of the lamp housing.

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] like Figures 1 to 7 As shown, in one of the embodiments of the present application, a heat dissipation type floodlight comprises a lamp housing 1, a plurality of light source parts 2 arranged in the lamp housing 1, end covers 3 assembled and connected to both ends of the lamp housing 1, and an adjustment bracket 4 connected to the end covers 3, a lamp board 5, a grille pressing plate 6 and a light-transmitting plate 7 are sequentially arranged on the light outlet of the lamp housing 1, a plurality of light source parts 2 are assembled on the lamp board 5, a plurality of through holes 61 are opened on the grille pressing plate 6, a plurality of light source parts 2 abut against the outer edges of the through holes 61 on a side away from the lamp board 5, the grille pressing plate 6 is assembled and connected to the lamp board 5, a first heat sink 11 and a second heat sink 12 are respectively arranged on the upper and lower ends of the lamp housing 1, a third heat sink 13 is arranged on the opposite side of the light outlet of the lamp housing 1, a power supply slot 14 is opened on the third heat sink 13, a power supply part 8 is assembled in the power supply slot 14, a part of the power supply part 8 is buried in the power supply slot 14, and another part of the power supply part 8 is exposed outside the power supply slot 14;

[0036] On one hand, the first heat sink and the second heat sink are respectively arranged at the upper and lower ends of the lamp housing, and the third heat sink is arranged at the side opposite to the light outlet of the lamp housing. By designing heat sinks on three sides of the lamp housing, the heat in the lamp housing can be quickly conducted and dissipated through the first heat sink, the second heat sink and the third heat sink. A power slot is provided on the third heat sink, and a power supply unit is installed in the power slot. A part of the power supply unit is buried in the power slot, and the other part of the power supply unit is exposed outside the power slot. Since the power supply unit is exposed on the third heat sink on the lamp housing, a part of the heat on the power supply unit can be directly dissipated into the air, and the remaining part of the heat is conducted into the air through the third heat sink, thereby accelerating the overall heat dissipation efficiency of the floodlight and saving the internal space of the lamp housing.

[0037] On the other hand of the present embodiment, a plurality of light source parts are mounted on the lamp board of the present application, a plurality of through holes are opened on the grille pressure plate, a plurality of light source parts are abutted against the outer edges of the through holes on the side away from the light board, and the grille pressure plate is assembled and connected to the light board, so that the grille pressure plate can produce a pressing and abutting effect on the light source part, thereby ensuring the structural stability of the light source part on the lamp board and avoiding the risk of the light source part detaching from the lamp board due to shaking.

[0038] like Figure 1 and Figure 4As shown, in the above embodiment, a plurality of air holes 31 are further provided on the end cover 3, a part of the air holes 31 is connected to the heat dissipation space of the third heat dissipation body 13, and another part of the air holes 31 is connected to the heat dissipation space of the first heat dissipation body 11 and the second heat dissipation body 12, and the air holes 31 are used to dredge the heat or rainwater residue in the heat dissipation space;

[0039] In this embodiment, by providing air holes on the end cover, the floodlight can drain away the accumulated water around the lamp housing through the air holes on rainy days, and can also drain away part of the heat on the lamp housing through the air holes on normal weather days.

[0040] like Figures 3 to 5 As shown, in the above embodiment, along the length direction of the lamp housing 1, the lamp housing 1 is provided with a heat insulation cavity 15 on one side close to the third heat sink 13, and a glue potting box 16 is provided in the heat insulation cavity 15;

[0041] In the present embodiment, a heat-insulating cavity is opened on the lamp housing on one side close to the third heat sink and a glue potting box is installed. Since the light source unit and the power supply unit are arranged opposite to each other, the lamp housing between the two will promote heat conduction or heat transfer, which is not good for the light source unit and the power supply unit. In order to effectively achieve the heat insulation effect between the two, the glue potting box is built into the heat-insulating cavity, which can facilitate the subsequent glue potting in the glue potting box, thereby achieving the role of heat insulation and support.

[0043] In this embodiment, the first heat sink, the second heat sink and the third heat sink are designed with heat sink fins that are arranged parallel to each other and have gaps, which can improve the heat dissipation effect and promote efficient heat dissipation into the air.

[0044] like Figure 1 and Figure 2 As shown, in the above embodiment, the adjustment bracket 4 is a U-shaped adjustment bracket, and the U-shaped adjustment bracket is connected to the end cover 3 by a hexagon socket countersunk screw 41;

[0045] In this embodiment, the adjusting bracket and the end cover of the floodlight are assembled using hexagon socket countersunk screws, which can facilitate assembly and disassembly.

[0046] like Figures 1 to 3 As shown, in the above embodiment, an angle scale 32 is engraved on the end cover 3, and an indicator line 42 is engraved on the open end of the U-shaped adjustment bracket, and the indicator line 42 points to the angle scale 32;

[0047] In this embodiment, the structural design of the angle scale on the end cover and the indicator line at the open end of the U-shaped adjustment bracket makes the angle adjustment of the floodlight more convenient and accurate, which is conducive to on-site installation and implementation.

[0048] like Figure 1 As shown, in the above embodiment, further, the U-shaped adjustment bracket is provided with a mounting hole 43 on the opposite side of the open end;

[0049] In this embodiment, a mounting hole is provided on the U-shaped adjustment bracket, which facilitates bolt assembly and fixing of the floodlight to the external platform on site.

[0050] like Figure 3 As shown, in the above embodiment, the light-transmitting plate 7 is a tempered glass;

[0051] In this embodiment, the light-transmitting plate is made of tempered glass, which is a conventional setting. It can enhance hardness, has good light transmittance, and protects the projection surface of the projection lamp.

[0052] like Figure 3 and Figure 4 As shown, in the above embodiment, a sealing ring 33 is further provided between the end cover 3 and the lamp housing 1, and the end cover 3, the lamp housing 1 and the sealing ring 33 are sealed and assembled and fixed by screws 34;

[0053] In this embodiment, the end caps, the lamp housing and the sealing ring are assembled and fixed by screw sealing, so that the end caps at both ends of the floodlight form a seal, which can prevent water vapor from entering and affecting the lighting effect of the floodlight.

[0055] In this embodiment, through the structural design of the stainless steel baffle, the card slot that is adapted to be plugged in with it, and the sealing ring connected to its side, when the light outlet of the lamp housing or the end covers at both ends are sealed with glue, the stainless steel baffle can further compact the sealing ring to prevent water vapor from entering the interior of the lamp housing, thereby avoiding short circuit damage to the electronic components on the lamp board due to moisture.

[0056] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the specification and drawings of the present invention, or directly or indirectly used in other related technical fields, is also included in the patent protection scope of the present invention.
