What Is This Tool?
This tool converts luminance values from lumen per square centimeter per steradian to kilocandela per square meter. It helps translate precise small-area brightness measurements into a standard unit widely used in displays, automotive HUDs, and outdoor signage.
How to Use This Tool?
-
Enter the luminance value in lumen/sq. cm/steradian.
-
Select the units you want to convert from and to: lumen/sq. cm/steradian to kilocandela/square meter.
-
Click the convert button to get the equivalent luminance in kilocandela per square meter.
Key Features
-
Converts high-precision luminance units used in micro-LED and OLED technology.
-
Supports photometric design and calibration involving small-area and high-intensity light sources.
-
Browser-based and easy to use for quick luminance unit translations.
Examples
-
0.5 lumen/sq. cm/steradian equals 5 kilocandela/square meter.
-
3 lumen/sq. cm/steradian equals 30 kilocandela/square meter.
Common Use Cases
-
Characterizing brightness of small or high-luminance sources such as micro-LED and OLED emitters.
-
Designing and measuring optical and photometric systems including lenses and illumination sources.
-
Specifying brightness levels for HDR displays, automotive instrument panels, and outdoor LED billboards.
Tips & Best Practices
-
Ensure consistent measurement conditions when comparing luminance values between different units.
-
Apply the conversion carefully due to large magnitude changes to avoid calculation errors.
-
Use the tool to align small-area luminance data with display or signage brightness standards for accurate specifications.
Limitations
-
The large conversion factor can produce large numeric values requiring careful handling.
-
Variations in measurement area size and environmental conditions may impact conversion accuracy.
-
Assumes uniform luminance distribution, which might not be valid for all real-world light sources.
Frequently Asked Questions
-
What does lumen/sq. cm/steradian measure?
-
It measures luminance as the luminous flux leaving or passing through a surface per unit area per unit solid angle, representing brightness on a very small scale.
-
Why convert to kilocandela per square meter?
-
Kilocandela per square meter is a standard unit used in display and signage industries to specify perceived brightness for larger areas.
-
Is the conversion factor fixed?
-
Yes, for this conversion, 1 lumen/sq. cm/steradian equals 10 kilocandela per square meter.
Key Terminology
-
Lumen/sq. cm/steradian
-
A photometric unit quantifying luminous intensity per unit area and solid angle, equivalent to candela per square centimetre.
-
Kilocandela/square meter
-
A luminance unit representing 1000 candelas per square meter, used to measure perceived brightness of surfaces.
-
Luminance
-
The luminous intensity emitted or reflected from a surface per unit area in a specific direction.
