How to choose LED light driver power?

Conventional lighting street lamps are separated from the power supply by the lamp cap. The common cause of failure is the lamp cap - high-pressure sodium lamp. The national standard for high-pressure sodium lamps stipulates a one-year warranty period, and the street lamp management unit will store a certain number of sodium lamps. High pressure sodium lamps have mature national standards, and their main accessory dimensions, power, and other main parameters are unified and interchangeable.
The current fault of LED lights mainly lies in the power supply, so the main issue is to solve the power supply problem. Due to the current lack of mandatory unified standards for LED power supplies, the power supplies on the market are independent, with single channel, multiple channels, and different sizes, making it difficult to replace. With the emergence of high-power LED street lights and LED tunnel lights on the market, LED driver power failures are frequent. In addition, LED street light driver power supplies often adopt built-in designs, which often makes it difficult to maintain LED light power supplies. In addition, some manufacturers lack after-sales repair services. As a result, complaints from homeowners are rampant, and after media exaggeration and promotion, it has caused misunderstandings about LED lights among the public, affecting the reputation of the LED industry.
LED light drive power supply
Intelligent control is one of the advantages of LED lighting fixtures, and power supply is the key to intelligent control
Intelligent control has the most mature conditions and obvious effects in the application of LED street lights and LED tunnel lights. Intelligent control can achieve stepless control of lamp power at different time periods based on road traffic density, meeting application requirements and achieving huge energy-saving effects, which can save a lot of funds for road management units. The application of tunnel lighting can not only save energy, but also automatically adjust the brightness of tunnel entrances and exits according to the brightness outside the tunnel, providing drivers with a visual transition stage to ensure driving safety.
Heat dissipation and protection are the main external factors for power failure
Abandon more than 4 outputs and develop single or two outputs. Abandon large and large currents and develop small currents
The more output paths, the more complex they become. The cost of resolving current interference between different outlets is high, and if not resolved, the fault rate is higher. In addition, the more output paths there are, the greater the total output current. Current is the main cause of heat generation, and the voltage itself does not directly cause heat generation. Simply put, the heat generation is proportional to the square of the current. In other words, if the current increases by 2 times, the heat generation will increase by 4 times, and if the current increases by 3 times, the heat generation will increase by 9 times. In summary, the failure rate of LED light power supply with single or dual output will be significantly reduced.
Abandon high-power and high-power options and choose relatively stable small and medium-sized power sources
Because the higher the power, the greater the heat generated, and the more compact the components inside, it is not conducive to heat dissipation, and temperature is the culprit for power failure. Furthermore, low-power power sources have relatively mature development, with advantages in stability and cost. In fact, many high-power power supply solutions have not undergone time validation and practical proof, and are hastily launched projects, all experimental products, resulting in endless failures. In contrast, small and medium-sized power sources have developed earlier and their technical solutions are much more mature.
