Description

Technical Field

[0001] The utility model relates to the technical field of LED street lamps, and more specifically, to a novel LED street lamp. Background Art

[0002] LED street lights are street lights that use LED light panels as lighting sources. Compared with traditional street lights, LED street lights not only have the characteristics of good color, high brightness and low heat, but more importantly, they are more energy-efficient than traditional street lights.

[0003] In the manufacturing of existing LED street lights, the controller and LED light board are integrated into a protective shell, and the protective shell is sealed by bolts or glue. However, when replacement and maintenance are required, cumbersome disassembly is required, and the shells split into multiple pieces are separated independently and easily fall off. In view of this, we propose a new type of LED street light. Utility Model Content

DETAILED DESCRIPTION

[0020] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] This embodiment provides a new type of LED street lamp. Figure 1-4, including a lamp pole 1 and a lamp holder, the lamp holder is installed at the top of the lamp pole 1 for lighting, the lamp holder includes a lamp board 3, the lamp board 3 uses an LED lamp board, a shell 2 is installed on the outside of the lamp board 3, the shell 2 adopts a shell divided into upper and lower parts, that is, the shell 2 includes a shell 1 21 and a shell 2 22. In normal use, first, the ends of the shell 1 21 and the shell 2 22 are assembled and connected by a connecting frame 8, and secondly, a buckle frame 23 is installed on the outer wall of the shell 2 22 away from the connecting frame 8. The buckle frame 23 cooperates with the connecting frame 8 to press and fix the shell 1 21 and the shell 2 22 to form a whole, which plays a role of protection and installation. When maintenance is required, refer to Figure 3 A buckle groove 25 cooperating with the buckle frame 23 is provided on the vertical outer wall of the shell 1 21. After the buckle frame 23 is separated from the buckle groove 25, the left end of the shell 22 can be lifted. At this time, the shell 22 is rotated and lifted around the connecting frame 8 to form an open angle for maintenance. However, after the buckle frame 23 is removed, the shell 22 is not separated from the connecting frame 8, and the shell 1 21 and the shell 2 22 are still connected as a whole, which can prevent the shell 2 22 from falling off from the shell 1 21, ensure stability during maintenance, avoid the shell 2 22 from falling to the ground and being damaged, and prevent the progress of maintenance from being affected.

[0022] Reference Figure 4 The connecting frame 8 includes a connecting frame 1 81 and a connecting frame 2 82. The connecting frame 1 81 is fixedly connected to the housing 1 21 by bolts. At the same time, the connecting frame 2 82 is connected to the housing 2 22 by bolts. Moreover, a rocker arm 2 84 and a relay arm 85 are connected between the connecting frame 1 81 and the connecting frame 2 82. The connecting frame 1 81 and the connecting frame 2 82 are movably connected to ensure that the housing 1 21 and the housing 2 22 can be unfolded. Moreover, the setting of the relay arm 85 enables the unfolding angle of the housing 1 21 and the housing 2 22 to be adjustable. A larger and sufficient maintenance space is provided. At the same time, a notch 86 is provided at the end of the connecting frame 81 for sliding contact with the relay arm 85. When the shell 1 21 and the shell 2 22 are in a closed state, the relay arm 85 will be stuck in the notch 86, and the inner wall of the notch 86 fixes the position of the relay arm 85 through friction. At this time, the shell 1 21 and the shell 2 22 are connected to one end of the connecting frame 8 to prevent loosening during use, thereby ensuring that the shell 1 21 and the shell 2 22 are stably combined during use.

[0023] Reference Figure 4There are two relay arms 85. During production, one end of the two relay arms 85 is hinged and the other end is left empty. Then, one of the relay arms 85 is hinged to the rocker arm 2 84, and the other is hinged to the connecting frame 2 82. At this time, the relay arm 85 hinges the rocker arm 2 84 and the connecting frame 2 82 in series. The two relay arms 85 further increase the opening angle of the shell 1 21 and the shell 2 22. Moreover, the vertical side walls of the two relay arms 85 are in sliding contact with each other. When they overlap with each other, they can be pulled together by friction, which further improves the stability and firmness of the combination of the shell 1 21 and the shell 2 22, and they will not open without a large external force.

[0024] Reference Figure 3 There is a rocker arm 1 83 movably connected between the connecting frame 1 81 and the connecting frame 2 82. When unfolded, the connecting frame 2 82 can be limited and supported by the rocker arm 1 83. After opening, the right end of the shell 22 will be buckled on the outer side of the right end of the shell 1 21 until the shell 1 21 and the shell 2 22 form an angle of ninety degrees. At this time, the shell 22 is tightened to the right end of the shell 1 21 by the shell 1 21 and the rocker arm 1 83. During the maintenance process, the shell 22 can remain stable and will not rock back and forth, which will not affect the normal progress of the maintenance. The rocker arm 1 83 and the rocker arm 2 84 are staggered to prevent mutual interference between the rocker arm 1 83 and the rocker arm 2 84, ensuring that the rocker arm 1 83 and the rocker arm 2 84 can complete the swing.

[0025] Reference Figure 2 A connecting seat 24 that cooperates with the connecting frame 82 is installed on the inner wall of the outer shell 22. The connecting seat 24 is located on the right side of the outer shell 22, and the connecting seat 24 is connected to the connecting frame 82 by bolts. When the outer shell 22 is unfolded and still interferes with the maintenance operation, the bolts between the connecting seat 24 and the connecting frame 82 can be removed. At this time, the outer shell 22 can be completely removed to adapt to more special maintenance scenarios and further improve the flexibility of equipment use.

[0026] Reference Figure 2 A sealing frame 6 is installed at one end of the lamp board 3 located on the inner side of the shell 2. The edge of the sealing frame 6 is installed at the joint position of the lamp board 3 and the shell 2, which can seal the welding point harness on the top surface of the lamp board 3 to avoid direct contact with the humid air from the outside. At the same time, a fin 5 is installed at one end of the sealing frame 6 located on the inner side of the shell 2, which can achieve smooth heat dissipation of the lamp board 3 by increasing the contact area with the outside air. In addition, a through hole 27 cooperating with the fin 5 is provided on the side wall of the shell 22, so that the inside of the shell 2 is connected with the outside air. When the fin 5 heats up, the still air around the fin 5 will expand and overflow, and the cold air flow from the outside will form a circulating airway through the through hole 27, which is continuously replenished to replace the air heated by the fin 5, thereby achieving non-direct contact air cooling of the lamp board 3.

[0027] Reference Figure 2 and Figure 3 A controller 4 and a power module 7 are installed on the inner side of the outer shell 21 on one side of the lamp board 3. The controller 4 and the power module 7 assist the lamp board 3 in lighting and shutting down, and are arranged side by side with the lamp board 3 without blocking each other in the height direction, which is convenient for heat dissipation and can also be easily inspected and maintained separately. A connecting sleeve 26 is installed between the controller 4 and the power module 7 on the outer shell 21. The connecting sleeve 26 is used to connect the lamp pole, and the wiring harness can be routed along the lamp pole and connected to the external power supply and electrical control box for normal use.
