Description

Technical Field

[0001] This utility model relates to the field of high mast lighting technology, and in particular to an energy-saving high mast lighting. Background Technology

[0002] High-mast lights are lighting devices typically over 15 meters high, consisting of a light pole and a high-power combined lighting structure. They are mainly used in freight yards, highways, stadiums, overpasses, and other locations requiring large-area lighting. High-mast lights are generally characterized by high brightness, high power, and high heat generation. To achieve energy conservation, existing technologies include using microwave or infrared sensors to detect the area around the high-mast lights and then controlling their on / off states. For example, Chinese patent documents CN105979664B and CN205883646U disclose an intelligent lighting system for high-mast lights in large urban squares, which can turn the lights on and off as needed based on vehicle and pedestrian traffic, adjusting the illuminance in real time to achieve energy savings. However, its detection range is usually small, covering only about 10 meters, and there is also the problem of sensor false triggering.

[0003] In addition, to prevent the lamps from overheating, existing technologies often use large-area heat dissipation shells, which increases the size of the lamps. The larger size places higher demands on the stability of the lamps when installed at high altitudes and also greatly increases the safety risks. Utility Model Content

[0004] The present invention aims to provide an energy-saving high mast light to solve the problems of small sensing range and large heat dissipation structure of existing high mast lights.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] An energy-saving high mast light includes: a light pole, a light panel disposed at the top of the light pole, a floodlight assembly connected to the light panel, and a sensor radar installed on the light;

[0007] The floodlight assembly includes:

[0008] Light source, which is mounted on the base plate;

[0009] The heat dissipation section is located on one side of the base plate and includes a plurality of parallel heat dissipation fins. Each heat dissipation fin has a fixed end and a free end. Each heat dissipation fin is provided with a flow guide groove. The flow guide groove extends from the free end to the fixed end, and the groove width decreases from the free end to the fixed end.

[0010] A driving power supply is electrically connected to the light source and is mounted on the heat dissipation unit.

[0011] Preferably, the bottom of the flow guide groove is arc-shaped and the opening of the groove is chamfered; two flow guide grooves are symmetrically arranged on the heat sink.

[0012] Preferably, the energy-saving high mast light further includes a light shield, which is positioned above the light source.

[0013] Preferably, the base plate is provided with support ears on both sides;

[0014] The two sides of the light shield are respectively installed and fixed on the lugs.

[0015] Preferably, the energy-saving high mast light further includes a bracket; the bracket includes:

[0016] Mounting plate, the mounting plate being adapted to be fixedly connected to the lamp panel;

[0017] Side plates are provided on both sides of the mounting plate, and the ends are provided with mounting holes suitable for connecting with the lugs.

[0018] Preferably, a transition plate is provided between the mounting plate and the side plate.

[0019] Preferably, the transition plate is arc-shaped, with one side connected to the mounting plate forming a first connecting line, and the other side connected to the side plate forming a second connecting line; the first connecting line and the second connecting line are parallel; or,

[0020] The transition plate is triangular, with the first vertex of the triangle located at the intersection of the mounting plate and the side plate; the second vertex located on the mounting plate; and the third vertex located on the side plate.

[0021] Preferably, the energy-saving high mast light further includes a drive cover; the drive cover is disposed on the drive power supply.

[0022] Preferably, the drive cover is provided with vent holes and is mounted on the heat dissipation part by mounting posts.

[0023] Preferably, the sensing radar is mounted on the light pole using a clamp.

[0024] The above-described solution of this utility model has at least the following beneficial effects:

[0025] The energy-saving high-mast light of this invention includes a light pole, a light panel at the top of the light pole, a floodlight assembly connected to the light panel, and a sensor radar mounted on the light pole. The floodlight assembly includes a light source, a base plate, a heat sink, and a driving power supply. The heat sink is located on one side of the base plate and includes multiple parallel heat sinks. The heat sink includes a fixed end and a free end. The heat sinks have guide grooves that extend from the free end to the fixed end, with the groove width decreasing from the free end to the fixed end. The driving power supply is electrically connected to the light source and is mounted on the heat sink. This energy-saving high-mast light uses a sensor radar as a detector, utilizing the microwave Doppler effect to achieve a detection range of 10-30 meters. It can detect moving targets on the ground at long distances, and can trigger the switching on and off of the high-mast light and adjust its brightness based on the movement of vehicles and people, thus achieving more effective energy-saving management.

[0026] Furthermore, the heat sink of this invention is provided with a guide groove; the guide groove extends from the free end to the fixed end, and the groove width decreases from the free end to the fixed end. Compared to a complete heat sink without a guide groove, this structure easily generates turbulence in the flowing air. Under turbulent conditions, the air exchanges heat more fully with the surface of the heat sink, improving heat dissipation efficiency. Moreover, the guide groove is not a straight groove with a rectangular cross-section, but rather a groove with a trapezoidal cross-section, wider at the opening and narrower at the bottom. This structure facilitates airflow entering the groove and accelerating and redistributing the flow direction within it, avoiding the formation of stagnant airflow zones due to slow flow velocity. This allows more areas of the heat sink surface to contact the flowing air, enhancing convective heat exchange between the air and the heat sink, and improving heat dissipation efficiency. Due to the increased heat dissipation efficiency, a smaller heat dissipation structure can be used in lamps of the same power, avoiding the increased installation difficulty and safety risks caused by an excessively large heat dissipation structure.

[0038] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0039] An embodiment of this utility model proposes an energy-saving high-mast light, such as... Figure 1-10 As shown, it includes: a lamp post 1, a lamp panel 2 located at the top of the lamp post 1, a floodlight assembly 3 connected to the lamp panel 2, and a sensor radar 4 installed on the lamp post 1;

[0040] The floodlight assembly 3 includes: a light source 31, a base plate 32, a heat sink 33, and a driving power supply 34; the light source 31 is mounted on the base plate 32; the heat sink 33 is located on one side of the base plate 32 and includes a plurality of parallel heat sinks 331; each heat sink 331 includes a fixed end 3311 and a free end 3312; a guide groove 332 is provided on the heat sink 331; the guide groove 332 extends from the free end 3312 to the fixed end 3311, and the groove width decreases from the free end 3312 to the fixed end 3311; the driving power supply 34 is electrically connected to the light source 31 and is mounted on the heat sink 33.

[0041] In this embodiment, the sensing radar 4 can sense moving targets on the ground at a long distance, thereby helping to trigger the switching on and off of the high-mast light and adjust its brightness based on the movement of vehicles and people, achieving more effective energy-saving management. The energy-saving high-mast light described in this embodiment can be controlled by connecting to an existing intelligent control system to control the on / off or dimming of the light source 31. For example, data can be collected by the sensing radar 4, uploaded to a centralized control module via a communication module, judged by the centralized control module, and a command sent to the lighting control module. The lighting control module then drives the driving power supply 34 to control the on / off or dimming of the light source 31. The driving power supply 34 can be a 0-10V / DMX / DALI drive, and the light source can be an LED light.

[0042] It should be noted that the energy-saving high mast light described in this embodiment can also be controlled by a variety of existing control systems. For example, a manual button, a timer, or other sensors can be connected to the input terminal of the PLC controller. The output terminal of the PLC controller is connected to an intermediate relay. The PLC controller is connected to an AC contactor through the intermediate relay. The output terminals of the AC contactor are electrically connected to the drive power supply 34, and the drive power supply 34 controls the light source 31.

[0043] To achieve the purpose of this utility model, it is sufficient to control the opening, closing or dimming of the light source 31 based on the sensing radar 4. Those skilled in the art can use existing control methods and control systems in the prior art to achieve this. This utility model does not limit this, nor does it limit what kind of control is performed under what circumstances. Those skilled in the art can set up control schemes as needed, for example, to achieve on-demand lighting, with lights turning on when a car approaches and turning off when the car leaves.

[0044] In this invention, the flow guide groove 332 extends from the free end 3312 to the fixed end 3311, and the groove width decreases from the free end 3312 to the fixed end 3311. That is, the width at the opening of the flow guide groove 332 is greater than the width at the bottom, forming a trapezoidal structure.

[0045] To achieve better heat exchange efficiency in the heat dissipation section 33, such as Figure 7 , 8 As shown, the bottom of the flow guide groove 332 is arc-shaped, and the opening is chamfered; two flow guide grooves 332 are symmetrically arranged on the heat sink 331. This structure is more conducive to reducing airflow resistance and extending the service life of the heat sink 331.

[0046] To concentrate the beam of the light source 31, the floodlight assembly 3 also includes a light shield 35, which is positioned above the light source 31.

[0047] To facilitate the installation of the light shield 35, the base plate 32 is provided with lugs 36 on both sides; the two sides of the light shield 35 are respectively installed and fixed on the lugs 36.

[0048] It should be noted that the connection between the lamp panel 2 and the floodlight assembly 3 can be achieved in various ways. This embodiment provides a preferred implementation. The energy-saving high mast light also includes a bracket 5, which includes a mounting plate 51 and a side plate 52. The mounting plate 51 is adapted to be fixedly connected to the lamp panel 2. The side plate 52 is located on both sides of the mounting plate 51, and its end is provided with a mounting hole 53 adapted to be connected to the lug 36.

[0049] In this embodiment, the mounting plate 51 has two elongated holes and one round hole, through which the bracket 5 can be mounted on the lamp panel 2 as needed. The lug 36 has a hole that mates with the mounting hole 53, and is bolted to the mounting hole 53 on the side plate 52 through the hole. This structure allows for adjustment of the relative position of the floodlight assembly 3 and the bracket 5 during installation, thereby adjusting the angular position of the floodlight assembly 3 and the lamp panel 2 when the floodlight assembly 3 is mounted on the lamp panel 2 via the bracket 5.

[0050] To protect the driving power supply 34, the floodlight assembly 3 further includes a driving cover 37; the driving cover 37 covers the driving power supply 34. The driving cover 37 is provided with ventilation holes and is mounted on the heat dissipation part 33 by mounting posts 38.

[0051] In a preferred embodiment, a transition plate 54 is provided between the mounting plate 51 and the side plate 52. The transition plate 54 can disperse the stress at the connection between the mounting plate 51 and the side plate 52, ensuring the structural strength of the bracket 5.

[0052] For achieving the purpose of this utility model, the design of the transition plate 54 is not unique. This embodiment provides a specific design: the transition plate 54 is triangular, with the first vertex of the triangle located at the intersection of the mounting plate 51 and the side plate 52; the second vertex located on the mounting plate 51; and the third vertex located on the side plate 52. This structure has high stability and good structural strength.

[0053] like Figure 2-8 As shown, this is the floodlight assembly 3 of the energy-saving high mast light of this utility model. Figure 2-4 A schematic diagram of the overall structure from different perspectives; Figure 5 This is a schematic diagram of the structure without the light shield 35 installed; Figure 6-8 This is a schematic diagram of the structure without the light shield 35, drive cover 37, and bracket 5 installed.

[0054] As an alternative design approach to this embodiment, such as Figure 9-10 As shown, the transition plate 54 is arc-shaped, with one side connected to the mounting plate 51, forming a first connecting line at the connection point, and the other side connected to the side plate 52, forming a second connecting line at the connection point; the first connecting line and the second connecting line are parallel. The arc-shaped structure of the transition plate 54 allows for better stress transfer between the mounting plate 51 and the side plate 52, preventing stress concentration at the connection point and thus avoiding structural damage.

[0055] It should be noted that the installation method of the sensing radar 4 on the lamp post 1 is not unique. In this embodiment, the sensing radar 4 is installed on the lamp post 1 by means of a clamp 6.

[0056] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
