The application environment of outdoor lighting is complex and changeable, including thunderstorms, high temperatures in summer, low temperatures in winter and other natural phenomena. Therefore, compared with indoor environments, outdoor lighting has stricter requirements on the reliability of power drives.
For companies engaged in outdoor lighting applications, the quality of power supplies on the market varies widely, and the prices vary greatly, which makes it very difficult to identify the quality of power supplies. At present, it seems that the price of power supply is no longer the only determining factor for users to choose power supply. The maintenance cost of outdoor lighting later projects directly affects the profit margin of lighting projects. Therefore, when users choose a power supply, they will consider more factors such as the quality of the power supply, the reliability of the performance, and the comprehensive service capabilities of the enterprise.
1. Dustproof and waterproof performance is key
The outdoor environment is changeable, and natural factors such as rain and dust may cause damage to the LED power supply. Therefore, waterproof and dustproof performance has become the primary consideration when choosing an outdoor lighting LED power supply. It is recommended to choose a power supply product with a higher IP rating to ensure stable operation under harsh weather conditions.
Knock on the blackboard: IP rating is the waterproof and dustproof rating. IP is usually followed by two numbers: the first number indicates the solid protection level of the equipment, and the second number indicates the liquid protection level of the equipment. According to the different numbers on the product shell, the protective capability of the product can be quickly and easily determined.

2. Efficiency and stability are the core
The efficiency and stability of the LED power supply directly affect the performance and life of the lamp. A high-efficiency power supply can reduce energy loss and improve lighting effects; while a stable power supply can avoid problems such as flickering and damage to lamps. Therefore, when choosing an outdoor lighting LED power supply, you should pay attention to its efficiency, power factor and other performance indicators, and choose a power supply product with multiple protection mechanisms such as overload, short circuit, and overvoltage.
3. Pay attention to compatibility
Different LED lamps may require power supplies with different specifications and parameters. Therefore, when choosing an LED power supply for outdoor lighting, make sure it is compatible with the fixtures used. This includes matching in terms of voltage, current, power, etc., as well as compatibility of communication protocols and interfaces. Only by choosing a suitable power supply can the normal operation and stable performance of the lamp be ensured.
4. Security and authentication are essential
Safety is the first factor in the application of lighting products. Therefore, when choosing an outdoor lighting LED power supply, you should pay attention to its safety performance and certification status. Ensure that power products comply with national safety standards and pass relevant certifications and tests. At the same time, pay attention to checking the shell material, wiring method and other details of the power supply to ensure safety and reliability during use.
5. Cost-benefit needs to be weighed
When choosing an LED power supply for outdoor lighting, cost is also a factor that needs to be considered. However, we cannot just use price as the criterion for selection. It is necessary to comprehensively consider factors such as the performance, quality, and lifespan of the power supply, as well as the overall investment and long-term operating costs of the lamps. Choose cost-effective power supply products that can not only meet current lighting needs, but also reduce later maintenance and replacement costs.
Frequently Asked Questions about LED Waterproof Power Supply:
1. What should you pay attention to when choosing an LED waterproof power supply?
1. In order to extend the service life of the waterproof "constant voltage" power supply, it is recommended to choose a model with 20% more output power rating. For example, if the load is 120W, it is recommended to choose a 150W LED waterproof power supply, and so on, which can effectively extend the life of the waterproof power supply.
2. In addition, the working environment temperature of the waterproof power supply and whether there is additional auxiliary heat dissipation equipment need to be considered. When the ambient temperature is too high, the load is equivalent to an increase, so the waterproof power supply needs to reduce the output.
3. Corresponding power supply should be selected for street light power supply and conventional use.
4. Select relevant product certification and performance parameters, specifications, such as CCC/CE/PFC/EMC/ROHS/UL.
2. If a 300W waterproof power supply is needed, can two 150W waterproof power supplies be used and connected in parallel?
Cannot be connected directly. Because the 150W waterproof power supply is not designed with a parallel function, when the output voltages of two waterproof power supplies are different, the one with the higher voltage will bear most or all of the losses, resulting in rapid damage.
3. Why does the waterproof power supply fail to start up smoothly if the load is a motor, light bulb or capacitive load?
When the load is a motor, light bulb or capacitive load, the current is too large at the moment of startup, even far exceeding the maximum load of the waterproof power supply, so the waterproof power supply will not be able to start smoothly.
4. Why does the waterproof power supply appear to be protected during use, but can work normally after being turned off and turned on again?
Generally, there are two situations when a waterproof power supply is protected during use. First, it may be that the load is instantly overloaded, causing overload protection. It is recommended to increase the output power of the power supply or modify the overload design; second, the temperature rise is too high and over-temperature protection occurs. If the above situation occurs, the power supply will shut down because it enters the protection state. After the situation is resolved, it can return to normal when it is turned on again.
5. What other parameters need to be considered when choosing a waterproof dimmable power supply?
Input voltage specifications: Select the appropriate input voltage VAC (V) and frequency (HZ) according to the power grid used. If the power grid is unstable, a wide range of input voltage specifications should be selected, such as 90~264V or higher.
Load characteristics: Consider the type of load, such as a motor, light bulb, or capacitive load. Different load types may produce large current or voltage changes at the moment of startup or shutdown, so a suitable power supply needs to be selected to avoid overload or voltage backflow.
Output power: Determine the output power of the power supply based on the required LED lamp model, lamp beads and power requirements. In order to extend the life of the power supply, you can choose a model with an output power rating that is 30% greater than the actual demand.
Dimming function: If you need dimming function, you should choose a waterproof dimming power supply with dimmable function, which can adjust the light brightness according to needs, achieve energy saving and meet diverse lighting needs.
Working environment: Consider the working environment temperature of the power supply and whether there is additional auxiliary cooling equipment. Under excessively high ambient temperatures, the power supply needs to derate its output to ensure stable operation.
Protection level: Choose waterproof and dustproof requirements (IP level) according to the use environment. The main evaluation standard for the waterproof performance of waterproof switching power supply is about IPXX waterproof grade standard.
Efficiency and power factor: Pay attention to the efficiency and power factor of the power supply to ensure efficient and energy-saving working status.
Safety and electromagnetic compatibility: Ensure that the power supply meets safety regulations and electromagnetic compatibility requirements to ensure safety of use.
Other factors: Actual usage needs also need to be considered, such as size, warranty, after-sales service, etc.
When choosing a suitable waterproof dimming power supply for outdoor lighting, it is recommended to consult a professional power supplier or technical engineer to make a customized selection based on specific application scenarios and needs. At the same time, you should check the product's technical parameters, certification information, and user reviews before purchasing to ensure that the selected product meets your needs and is reliable.
