Power Consumption Formula:
From: | To: |
Definition: This calculator estimates the total power consumption of an LED screen based on the number of pixels and power consumption per pixel.
Purpose: It helps display designers, engineers, and technicians determine the power requirements for LED screens of various sizes and configurations.
The calculator uses the formula:
Where:
Explanation: The total power is calculated by multiplying the number of pixels by the power consumption of each individual pixel.
Details: Accurate power estimation ensures proper power supply design, thermal management, and energy efficiency for LED display installations.
Tips: Enter the total number of pixels in the screen and the power consumption per pixel (default 0.0005 watts/pixel for typical LEDs). All values must be > 0.
Q1: What's a typical power consumption per pixel?
A: Most standard LED pixels consume about 0.0005 watts, but this can vary based on LED type and brightness.
Q2: How do I find the number of pixels in my screen?
A: Multiply the screen's width (in pixels) by its height (in pixels). For example, a 1920×1080 screen has 2,073,600 pixels.
Q3: Does this include power supply inefficiencies?
A: No, this calculates only the LED power. Add 10-20% for power supply losses in real-world applications.
Q4: How does brightness affect power consumption?
A: Higher brightness settings increase power per pixel. Use manufacturer specs for specific brightness levels.
Q5: Can I calculate energy costs from this?
A: Yes, multiply total watts by operating hours, then by your electricity rate (per kWh) to estimate costs.
