Firstly, LEDs（Light Emitting Diodes）are semiconductor devices that convert electrical energy into light. However, in LED fixtures, an LED light driver is typically required to provide the necessary voltage and current to the LED chips.
In general, you can choose between a 12V or 24V LED power supply. In that way, understanding the differences between them can aid in making a more informed decision. Please read the following factors for your reference.
- Voltage Output
A 12V LED light driver outputs a voltage of 12V, providing this voltage to the LED chips. On the other hand, a 24V LED power supply outputs a voltage of 24V. In a series circuit, the 12V power supply can drive a fewer number of LED chips compared to the 24V power supply.
- Current Difference
With an increase in voltage, the current also proportionally increases. Therefore, a 24V LED power supply usually requires a larger current to drive the LED chips.
This implies that the 24V power supply can deliver more power, making it suitable for applications that require higher brightness in LED fixtures.
- Application Range
- 12V LED Light Driver: Suitable for smaller-scale LED lighting systems, such as home lighting and automotive lighting. The lower voltage allows sufficient power delivery over shorter power lines, making it suitable for low-power, low-brightness applications.
- 24V LED Light Driver: Suited for larger-scale lighting systems, like commercial and industrial lighting. Compared to 12V, the 24V LED light drivercan deliver more power, enabling LEDs to operate over longer distances. It also reduces line current, aiding in minimizing cable losses.
- Specific Usage
- For LED Strip Lighting
12V LED Light Driver: This driver is ideal for shorter LED cabinet strip lights applications in homes, such as cabinet or TV backlighting, where a less space is covered.
24V LED Light Driver: Ideal for commercial applications or bigger expanses of LED strip lighting, such as decorative lighting in bars, restaurants, or shopping malls, where consistent power delivery over longer distances is critical.
- For Indoor Commercial Lighting
12V LED Light Driver: Appropriate for small commercial spaces like cafes, small shops, or offices, where 12V LED fixtures can meet the lighting requirements.
24V LED Light Driver: More suitable for larger commercial spaces such as supermarkets, hotel lobbies, or exhibition halls, where a 24V LED lighting system can cover expansive areas.
After learning all these aspects, you can have a clear idea about why there are two voltage options?
The reason is that having two voltage options is mainly due to diverse application needs. Different scenarios require varying voltage and current to drive LED chips effectively.
For instance, large space illumination system or extensive LED displays demand higher voltage and current to ensure brightness and stability. Smaller LED fixtures typically use lower voltage and current to reduce costs and power consumption.
Conclusion
Choosing the right LED power supply voltage and current depends on specific application scenarios and requirements. Different voltage and current selections can impact LED fixture performance, cost, and power consumption. We hope these insights assist you in selecting the appropriate LED light driver.
