Description

Technical Field

[0001] This utility model relates to the field of floodlight equipment technology, and in particular to an outdoor floodlight. Background Technology

[0002] Floodlights, as a common outdoor lighting device, are widely used in squares, building facades, stadiums, and other places. Their performance directly affects the lighting effect and lifespan. With the continuous development of lighting technology, LED light sources have gradually become the mainstream light source for floodlights due to their advantages such as high luminous efficiency, long lifespan, and energy saving and environmental protection. However, LEDs still generate a lot of heat during operation. If this heat cannot be dissipated in a timely and effective manner, it will lead to accelerated light decay of the LED chips, shortened lifespan, and even malfunction of the luminaire. Therefore, heat dissipation performance has always been a key technical issue restricting the performance and reliability of floodlights.

[0003] Existing floodlights, such as the LED floodlight disclosed in patent number CN 223242668 U, include a lamp body and a bracket. A fixing plate is provided between the lamp body and the bracket, and the fixing plate has a rotating hole. The lamp body has a first through hole, and the bracket has a second through hole. A pin passes through the second hole, the rotating hole, and the first through hole in sequence to hinge the bracket, the fixing plate, and the lamp body. The fixing plate has an abutment plate that abuts against the lamp body, allowing the fixing plate to rotate with the lamp body. The bracket has a screw hole, and a locking bolt is screwed into the screw hole. Rotating the locking bolt abuts against the fixing plate, thus fixing the fixing plate and the lamp body. This utility model uses a pin connection between the lamp body and the bracket, placing the fixing plate between the lamp body and the bracket. By rotating the locking bolt screwed onto the bracket, the fixing plate is fixed, thereby fixing the illumination angle of the lamp body. This greatly improves the service life of the LED floodlight's angle adjustment function, and the structure is simple and easy to maintain.

[0004] The floodlight has mounting screw holes on the side of the housing, resulting in poor appearance integrity and difficulty in ensuring waterproof sealing performance. Secondly, the heat dissipation path of the floodlight is mostly concentrated on the heat sink, resulting in uneven heat conduction and easy heat accumulation. Especially in high-power applications, local high temperature will accelerate material aging and optical component degradation. Therefore, how to achieve efficient and uniform heat dissipation within a limited structural space, while ensuring the luminaire's simple appearance and reliable sealing, has become an urgent technical problem to be solved in this field. It is necessary to propose a new type of outdoor floodlight structure to optimize the heat dissipation path, improve the overall appearance, and enhance environmental adaptability, thereby meeting the higher standards of outdoor lighting requirements. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art by proposing an outdoor floodlight.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an outdoor floodlight, including a housing, a mounting bracket rotatably connected to the housing, a light source disposed inside the housing, a glass cover disposed on the housing, and a mounting port disposed at the bottom of the housing, a base sealed to the mounting port by a positioning component, and a heat dissipation component disposed on the base, wherein the heat dissipation component is connected to the light source for transferring the heat of the light source to the top of the housing.

[0008] Furthermore, the positioning component includes an inner groove formed along the inner wall of the mounting opening, a sealing ring disposed in the inner groove, and fixing bolts for fixing the base and the sealing ring in the inner groove.

[0009] Furthermore, the heat dissipation assembly includes a mounting plate fixed on the base, a central heat dissipation area disposed in the middle of the mounting plate, and peripheral heat dissipation areas symmetrically distributed on both sides of the central heat dissipation area.

[0010] Furthermore, the central heat dissipation area is provided with a first heat dissipation rib, and the outer heat dissipation area is provided with a second heat dissipation rib, wherein the distance between adjacent second heat dissipation ribs is greater than the distance between adjacent first heat dissipation ribs.

[0011] Furthermore, a power cord interface is provided at the bottom of the base.

[0012] The outdoor floodlight proposed in this utility model has the following advantages:

[0013] The outer shell of this utility model adopts a minimalist design with a beautiful and simple shape, which can effectively prevent moisture and dust from accumulating on the surface of the shell for a long time, avoiding the problem of reduced heat dissipation efficiency caused by dust accumulation, and ensuring that the lamp can still maintain good heat dissipation performance after long-term use. By setting the mounting port, base and positioning components at the bottom of the shell, the heat dissipation component is installed from the bottom of the shell, ensuring that there are no exposed screws on the front surface of the shell, improving the overall appearance and aesthetics of the product. By setting the heat dissipation component, the heat generated by the lamp source is efficiently transferred from bottom to top to the shell through the heat dissipation component package, and then the shell dissipates the heat to the outside air. Under the same lamp size, the structural design of the heat dissipation component in this utility model can achieve lighter weight and higher heat dissipation efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-3 An outdoor floodlight includes a housing 1, a mounting bracket 2 rotatably connected to the housing 1, a light source 3 disposed inside the housing 1, and a glass cover 4 disposed on the housing 1, the glass cover 4 being sealed to the housing 1. It also includes a mounting port 5 at the bottom of the housing 1, a base 6 sealed to the mounting port 5 via a positioning component 9, and a heat dissipation component 7 disposed on the base 6. The heat dissipation component 7 is connected to the light source 3 and is used to transfer heat from the light source 3 to the top of the housing 1. Preferably, in this embodiment, the housing 1 adopts a completely square shape structure with no chamfers or draft angles, resulting in a simple and robust design. This effectively prevents moisture and dust from accumulating on the surface of the housing 1 over a long period, avoiding the problem of reduced heat dissipation efficiency due to dust accumulation, and ensuring that the light fixture maintains good heat dissipation performance even after long-term use. The housing 1 and the mounting bracket 2 can be adjusted from 0 degrees to 180 degrees using an angle adjustment structure, facilitating installation and lighting layout. The angle adjustment structure is existing technology and will not be described in detail here.

[0019] In an optional embodiment of this utility model, the positioning component 9 includes an inner groove 901 formed along the inner wall of the mounting opening 5, a sealing ring 902 disposed in the inner groove 901, and a fixing bolt 903 for fixing the base 6 and the sealing ring 902 to the inner groove 901. After the base 6 is fixed, the mounting opening 5 is sealed by the base 6. The setting of the sealing ring 902 can further improve the sealing effect, thereby improving the waterproof level.

[0020] In an optional embodiment of this utility model, the heat dissipation component 7 includes a mounting plate 701 fixed on the base 6, a central heat dissipation area 702 located in the middle of the mounting plate 701, and peripheral heat dissipation areas 703 symmetrically distributed on both sides of the central heat dissipation area 702. The mounting plate 701 is connected to the lamp source 3, and the heat from the lamp source 3 is transferred to the central heat dissipation area 702 and the peripheral heat dissipation area 703 through the mounting plate 701.

[0021] In an optional embodiment of this utility model, the central heat dissipation area 702 is provided with a first heat dissipation rib 7021, and the outer heat dissipation area 703 is provided with a second heat dissipation rib 7031. The spacing between adjacent second heat dissipation ribs 7031 is greater than the spacing between adjacent first heat dissipation ribs 7021. The first heat dissipation ribs 7021 in the central heat dissipation area 702 are densely arranged to maximize the absorption and conduction of core heat, while the second heat dissipation ribs 7031 in the outer heat dissipation area 703 are loosely arranged to reduce the overall weight while ensuring sufficient heat dissipation area. The heat generated by the lamp source 3 is efficiently transferred from bottom to top to the outer shell 1 through the heat dissipation component 7, and then the outer shell 1 dissipates the heat into the outside air. Under the same lamp size, the structural design of the heat dissipation component 7 in this application can achieve lighter weight and higher heat dissipation efficiency.

[0022] In an optional embodiment of this utility model, a power cord interface 8 is provided at the bottom of the base 6. The power cord interface 8 is located at the bottom of the base 6, which effectively avoids the accumulation of rainwater and dust, and improves durability and long-term reliability.
