What is Candlepower Distribution Curve

Candlepower distribution curve is a graphical representation that illustrates how the intensity of light is distributed from a lamp or light fixture. This curve provides valuable information about the directionality and spread of light emitted by the fixture.

The curve is created by measuring the candlepower, which represents the intensity of light, at various angles in a specific plane. It visually depicts the light distribution pattern by showing the intensity of light emitted in each direction. The curve typically includes a horizontal line at 90°-270°, which divides the graph into two parts: the portion above represents indirect light shining above the fixture, while the portion below represents direct light shining down.

By analyzing the candlepower distribution curve, designers and users can gain insights into how the light is distributed and where it is directed. This information is crucial for making informed decisions about lighting placement and coverage. The curve helps determine the uniformity of illumination, calculate parameters like mean horizontal candle power (MHCP) and mean spherical candle power (MSCP), and assess the actual illumination of a surface.
