Description

Technical Field

[0001] The utility model relates to the field of street lamps, and more specifically, to an integrated power supply drive and single-lamp control device for LED street lamps. Background Art

[0002] With the continuous development of China's modernization drive, the country has placed higher demands on the ecological environment and resource utilization. Green ecology and energy conservation and emission reduction are among the requirements that are being continuously improved. At the same time, as a part of urban infrastructure, urban lighting systems have become one of the many key areas of energy conservation and emission reduction. As a new generation of low-carbon, green, environmentally friendly, and energy-saving lighting, LED streetlights are widely used in road lighting and urban landscape lighting. They are also gradually replacing existing streetlights that are outdated, have short service lives, poor quality and reliability, and high energy consumption.

[0003] Existing LED street lamp heads are mainly composed of a lamp housing, an LED light source module, a power driver, and a single-lamp controller. The LED light source is installed on the housing, and the power driver and single-lamp controller are arranged inside the lamp housing. All three are connected by cables. Because the power driver and single-lamp controller are inside the lamp housing, they will generate a certain amount of heat when working, and the heat generated inside the lamp housing cannot be discharged in time, which will have a certain impact on the service life of the LED light source module, the power driver, and the single-lamp controller. In addition, most LED street lamp failures or malfunctions are caused by failures or malfunctions of the power driver or single-lamp controller. Traditional power drivers or single-lamp controllers are placed inside the LED street lamp head. When repairing or replacing them, the lamp head needs to be disassembled and the internal cables need to be disconnected. After the repair and replacement are completed, the wiring needs to be reconnected. If personnel who are not familiar with or do not understand the circuit principles can easily connect the lines incorrectly, causing short circuits or other losses to the LED lamps, increasing safety risks.

[0060] Working principle: The integrated power supply driver and single-lamp control device of the present application is installed on the top of the LED lamp head. The LED lamp head includes a shell and an LED light source module installed on the shell. One side of the integrated power supply driver and single-lamp control device is connected to the LED light source module, and the other side is connected to the AC power.

[0061] During installation, the base unit is connected to the mains power supply and the LED light source module via a cable circuit. The base unit's mounting tube is then inserted into the housing's mounting hole and secured to the housing's threaded hole with a locking bolt inserted through the countersunk hole. The antenna's retaining plate is then engaged with the perforated hole in the protective cover and secured with a locking nut. The connector on the antenna cable end is then snapped into place with the antenna connector on the chip soldered to the control board. The drive control unit is then snapped into place with the protective cover. The drive control unit is then inserted into the slot on the base unit in a specific orientation. The second pin on the base contacts the first pin in the socket, completing the circuit. The driver board is soldered with various electronic components, and the corresponding pins are soldered to the corresponding pins on the base, forming an electrical device with a driving function. The control board is also soldered with various electronic components, and the corresponding pins are soldered to the pins on the driver board, forming an electrical device with a control function.

The base unit is designed with only plug-ins and cables and no electronic components, which greatly increases its lifespan and reduces the possibility of failure or malfunction. Therefore, when disassembling, only the drive control unit and protective cover need to be inspected. At the same time, the use of plug-in installation and disassembly makes installation, maintenance, and replacement more convenient and fast, saving time and effort. After disassembly, the failed integrated power driver and single-lamp control unit can be repaired again, and the repaired drive control unit can be reused, thus saving usage costs.
