LED fairground, unfortunately, are not as simple as traditional incandescent light bulbs when it comes to installation and set up. Because they run on low voltage DC, they require a power supply device that converts 12V/24V DC and 12V/24V AC (depending on your location) into the voltage signal that LED fairground lights can use. The LED lighting system of an amusement park usually includes various decorative lights, landscape lights, safety lighting, and special effect lights, so there are many aspects to consider when choosing a power source. Here are some key points:

How to choose a power supply for your LED fairground project
1. Determine the total power requirement
• Calculate the total power requirement for all LED fairground lights. Understand the rated voltage and current of the lights, then calculate the total power (power = voltage x current).
• Leave a certain power margin to cope with the natural loss of light or power efficiency that may be added in the future.
2. Choose the right power supply type
• Constant current power supply: Most LED fairground lights require a constant current power supply to ensure consistency in brightness and color, even when the voltage fluctuates.
• Constant voltage power supply: Some LED fairground lights may be designed to use a constant voltage power supply, which is usually used for simple or low-cost LEDfairground lights.
3. Power supply efficiency and safety
• Efficiency: Choosing a high-efficiency power supply can reduce energy consumption, reduce heat, and extend the life of the light.
• Certification: The power supply should have relevant safety certifications, such as UL, CE, FCC, etc., to ensure its safety in various environments.
4. Protection level and environmental adaptability
•The fairground environment may involve outdoor, humid or dusty conditions, so the power supply should have an appropriate protection level (such as IP65 or higher) to prevent water or dust from entering.
5. Dimming compatibility
•If dimming function is required, make sure the power supply supports dimming and is compatible with the dimmer you plan to use.
6. Installation and wiring considerations
•Installation space: Consider the size and installation location of the power supply to ensure that there is enough space for installation and maintenance.
•Wiring: Understand the input and output connection methods of the power supply and whether special cables or connectors are required.
7. Size and installation method:
•The size of the power supply should take into account the installation space of the luminaire to ensure that it can be easily installed near or inside the luminaire.
8. Backup power supply and redundancy:
•For occasions where continuous lighting is required, consider using a power supply with backup power supply or redundant design to improve system reliability and availability.
When selecting a power supply, it is recommended to refer to the technical specifications provided by the manufacturer of the LED fairground luminaire, or consult a professional electrical engineer to ensure that the power supply is fully matched with the luminaire to avoid potential problems. By carefully considering the above factors, you can choose a safe and efficient power supply for your LED fairground project, ensuring that the lighting system can operate stably under various conditions and provide visitors with the best visual experience.
