What Is This Tool?
This tool converts illuminance values from lux, the SI unit measuring luminous flux per square meter, to lumen per square centimeter, which measures luminous flux on a much smaller surface area. It is designed for users needing to express brightness on small surfaces such as LEDs or microscope slides.
How to Use This Tool?
- Enter the illuminance value in lux into the input field.
- Select 'lux [lx]' as the input unit if required.
- Choose 'lumen/square centimeter' as the output unit.
- Click convert to see the equivalent value in lumen/cm².
Key Features
- Converts illuminance from lux (lx) to lumen per square centimeter easily.
- Based on the direct conversion factor where 1 lux equals 0.0001 lumen/cm².
- Supports use cases in lighting design, lab photometry, and display calibration.
- Browser-based and user-friendly interface ideal for precise measurements.
Examples
- 500 lx converts to 0.05 lumen/cm² by multiplying by 0.0001.
- 10,000 lx converts to 1 lumen/cm² using the same conversion factor.
Common Use Cases
- Lighting design and standards for indoor environments like offices or classrooms.
- Measuring and calibrating brightness of small high-power LEDs and LED components.
- Laboratory photometry applications such as evaluating illuminance on microscope slides.
- Calibrating or comparing brightness of small displays and optical instruments.
Tips & Best Practices
- Ensure surface area measurements are accurate and units are consistent for meaningful results.
- Remember that lumen/cm² applies to much smaller surfaces than lux; interpret results accordingly.
- Use this tool primarily for uniform illumination conditions since it doesn't account for directional or spectral light variations.
Limitations
- Conversion relies on assuming uniform illumination across the surface area.
- Does not consider directional lighting effects or changes in light spectrum.
- Accurate surface area data is essential as lumen/cm² refers to much smaller areas than lux measurement.
Frequently Asked Questions
- What is the relationship between lux and lumen per square centimeter?
- One lux equals 0.0001 lumen per square centimeter; the tool uses this direct conversion factor.
- In what scenarios would I convert lux to lumen/cm²?
- Common scenarios include measuring brightness of LEDs, microscope slides, or small display surfaces where per-centimeter square illumination is relevant.
- Does this conversion account for different types of lighting or spectral variations?
- No, the conversion assumes uniform illumination and does not consider directional light or spectral changes.
Key Terminology
- Lux [lx]
- The SI derived unit of illuminance, measuring luminous flux incident per square meter, weighted by human photopic vision.
- Lumen/square centimeter
- A photometric unit measuring luminous flux per square centimeter, useful for brightness on small surfaces and convertible from lux.
- Illuminance
- The amount of luminous flux falling on a unit area of a surface, representing perceived brightness.
