Description

Technical Field

[0001] The utility model relates to the field of LED street lamps, and more specifically, to a quickly disassembled and assembled LED street lamp driver. Background Art

[0002] LED street lights are a new generation of low-carbon, green, environmentally friendly, and energy-saving lighting, widely used in road lighting and urban landscape lighting. Existing LED street light heads primarily consist of a housing, an LED light source module, and a power driver. The LED light source module is mounted on the housing, while the power driver is located inside the housing, connected by a cable.

[0003] LED street lights have the characteristics of long life, energy saving, green environmental protection, high brightness, and high stability. The theoretical life of the light source is more than 50,000 hours. Calculated by lighting for 12 hours a day, the lighting life of the LED street light can reach 10 years. However, most LED street lights fail before reaching this time point. The main reason for their failure is the failure of the LED driver, and the life of its power supply cannot be guaranteed.

[0004] Currently, most LED driver manufacturers on the market offer a 3-5 year warranty. When the driver fails, the housing needs to be opened to replace the power driver. Replacing the driver on a street lamp is time-consuming and laborious, requiring tools to open the top cover of the LED street lamp head and remove multiple internal circuits. This makes maintenance complex, resulting in the need to replace the entire lamp for engineering maintenance. Utility Model Content

[0048] Working principle: As shown in the figure, the drive unit is installed above the LED lamp head. The LED lamp head includes a shell, which is provided with an LED light source module and a corresponding lens. The base unit is fixed to the shell by a locking bolt. The shell has a mounting through-hole that allows the insertion tube to pass through, the socket has a countersunk hole that cooperates with the locking bolt, and the shell has a threaded hole that cooperates with the locking bolt. The base unit is connected to the mains and the LED light source module through cables respectively; the drive board inside the drive unit is electrically connected to the base and provides the LED light source module with converted electrical energy suitable for the LED light source module; the drive unit is located outside the LED lamp head and is physically isolated from the LED light source module, and the outer cover is made of aluminum, which helps to dissipate heat from the drive board and the light source module, thereby extending the service life of the drive board unit and the light source module.

[0049] During the specific installation, first weld the first plug-in to the cable, then place the first plug-in into the installation cavity of the base unit, and at the same time, pass the cable through the wire hole on the sealing column, then align the notch on the sealing column with the protrusion of the insertion part, press the sealing column into the insertion part, and use fixing bolts and fixing nuts to fix the sealing column and the socket part.

[0050] Next, the card plate on the transition plate is snapped into place with the slot on the circuit board. The positioning posts on the base are then aligned with the positioning holes on the transition plate and pressed into place. The mated base and driver board are then placed into the housing. The base is pressed until the groove on the base engages the wedge-shaped block inside the housing, forcing the upper sealing ring into contact and compression with the boss on the housing. Various electronic components are soldered to the surface of the circuit board, and these components are then soldered to the second insert, forming an electrical device with driving functionality.

[0051] Then put the sealing gasket under the socket part, and then connect the cables of the base unit to the mains power and LED light source module as required, and then insert the insert part into the mounting hole above the shell and fix it with the locking bolt.

[0052] Then insert the drive unit into the slot on the base unit according to the direction, so that the second plug-in piece on the drive unit contacts the first plug-in piece in the base unit to form a loop and the installation is completed.

[0053] When the drive fails, you only need to pull out the drive unit and repair or replace a new drive board. A slot is set on one of the wedge blocks in the outer cover. When disassembling, use a tool to reach into the slot and gently pry the groove on the base to remove the base, saving time and effort and improving maintenance efficiency.

[0054] Although the present invention has been illustrated and described with respect to preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
