Description

LED street light

technical field

The invention relates to road lighting technology, in particular to a modular LED street lamp.

Background technique

Because of the advantages of energy saving and long service life, the application of semiconductor lighting in high-power road lighting is becoming more and more popular, and there is a tendency to gradually replace traditional lighting technology.

Traditional LED street lamps are generally composed of a lamp body, a light-emitting module, and a heat dissipation module. When repairing or maintaining, the entire lamp needs to be removed or long-term high-altitude operations can be completed. The following documents belong to this LED street lamp.

Chinese patent document CN101101103A disclosed a LED street lamp on January 9, 2008. The LED street lamp includes a lamp body and an LED bulb. The lamp body includes a head section, a middle section, and a tail section. Docking with the tail section; there is a gasket between the head section and the middle section, and the head section is connected to the middle section through fasteners; there is a gasket between the tail section and the middle section, and the tail section is connected to the middle section through fasteners; the middle section is A profile has the same cross-section at different positions along the length direction of the profile; this patent document provides a modular assembled LED street lamp that has good heat dissipation performance and products with different shapes and specifications can share a set of molds.

The deficiency of the aforementioned patented technology in terms of repair and maintenance is obvious, either working at heights for a long time, or dismantling the whole lamp, which is not very convenient.

In order to solve the above problems, some people have proposed a frame-type LED street lamp composed of a plurality of light-emitting modules that are separately removed and maintained. During maintenance, only the faulty module is removed, and a normal light-emitting module is installed in time, and the base is returned to the base. Then repair the faulty modules uniformly. The following documents belong to this LED street lamp.

Chinese patent document CN101105272A disclosed an LED street lamp on January 16, 2008. The description of the patent document records: as shown in Figures 9 to 13, the present invention also provides an LED lamp, including a frame 4, at least one installation The lighting module 5 on the frame 4, the lighting module 5 includes a radiator 6, a substrate 7 with an LED array, a PCB 8 and a lens cover 9 with a lens array.

Each through hole 80 corresponds to each LED of the LED array one by one, for each LED 70 in the LED array to pass through. The circuit on the PCB board 8 is connected to each LED electrode; the structure of a single lens 90 in the lens array of the lens cover 9 is exactly the same as the lens structure shown in FIGS. 1 to 4 , and will not be described again here. The heat sink 6 is provided with a plurality of cooling fins 60, and the bottom surface of the heat sink 6 is provided with a groove 62, the substrate 7 is installed on the bottom of the groove 62 by means of a thermally conductive insulating pad 71, and the PCB board 8 is mounted on the outer surface of the substrate 7, And lens cover 9 is installed on the outside of PCB board 8 again, and each LED 70 on the substrate 7 passes through the through hole 80 on the PCB board 8 and is positioned at the circle center of the pit corresponding to a lens 90 on the lens cover 9. A frame 92 with a through hole 920 is disposed on the periphery of the lens cover 9 , and the lens cover 9 is mounted on the radiator 6 by passing through the through hole 920 and being locked on the radiator 6 by means of a screw 93 . A sealing ring 94 is also provided between the frame 92 of the lens cover 9 and the heat sink 6, so that it can play a good sealing, waterproof and dustproof effect, so as to protect the internal circuit and LED. Moreover, several positioning columns 96 are provided on the frame 92 of the lens cover 9 , and positioning holes 940 for inserting the positioning columns 96 to position and fix the sealing ring 94 are correspondingly provided on the sealing ring 94 . The frame 4 is divided into several installation holes 42 by several frame sides 40 arranged in a criss-cross pattern, and one lighting module 5 is installed in each installation hole 42 . In the embodiment shown in FIG. 7 , the frame 4 is divided into six mounting holes 42 , and a lighting module 5 is installed in each mounting hole 42 , and each lighting module works independently. This design makes installation and subsequent maintenance more convenient, and when one of the lighting modules 5 is damaged, only this lighting module 5 needs to be replaced instead of the entire lamp, which makes the maintenance work very easy. It is easy and saves a lot of maintenance cost, and when replacing, other lighting modules 5 work as usual for lighting without affecting the road lighting function. Two sides of the heat sink 6 of the lighting module 5 are provided with mounting edges 64 with screw holes 640 thereon, and the frame edge 40 around the mounting hole 42 of the frame 4 is correspondingly provided with screw holes 400 . When assembling, the main body of the lighting module 5 is accommodated in the mounting hole 42, and the mounting edge 64 of the radiator 6 rests on the frame edge 40, and is locked in the screw hole on the mounting edge 64 of the radiator 6 by means of screws 45 640 and the screw holes 400 on the frame edge 40 of the frame 4 to fix the lighting module 5 on the frame edge 40 .

The technical solution provided by the above patent documents provides a modular street lamp based on screw connection. The modules are connected to the frame by screws. When a certain module needs to be repaired, the module can be directly removed, which is relatively convenient. .

However, the shortcomings of the aforementioned second patent document are also obvious. When working at heights, it is necessary to remove the faulty module and install the normal module, and it is not very convenient to complete a whole set of screw disassembly and assembly work.
