Product DetailsLight source plays a pivotal role in photoelectric instruments, defining crucial parameters such as luminous flux, illuminance, luminous intensity, and more.
- Luminous Flux Luminous flux represents the total optical power emitted by a light source in all directions over time. It's measured in lumens (lm), indicating the amount of light energy emitted.
- Illuminance Illuminance refers to the luminous flux received per unit area and is measured in Lux (lx). It quantifies the brightness perceived on a surface illuminated by a light source.
- Luminous Intensity Luminous intensity measures the luminous flux emitted within a unit solid angle and is expressed in Candela (cd). It indicates the brightness perceived from a specific direction.
- Luminance Luminance characterizes the brightness level on a surface and is measured in Candela per square meter (cd/m²). It accounts for the luminous flux reflected from or emitted by a surface.
- Spectral Power Distribution Light from a source comprises radiation with various wavelengths, each with different power levels. The spectral power distribution describes how the radiant power is distributed across different wavelengths.
- Black Body A theoretical concept used as a standard for studying thermal radiation. While true black bodies don't exist in nature, they represent ideal objects that absorb all incident electromagnetic radiation and emit radiation based solely on temperature.
- Color Temperature Color temperature describes the color appearance of light emitted by a source compared to that of a theoretical black body at a particular temperature. It's measured in Kelvin (K) and provides insight into the perceived color of the light.
- Color Rendering Color rendering evaluates how accurately a light source renders colors compared to a reference standard. It quantifies the ability of a light source to reveal the true colors of objects under illumination, influenced by its spectral power distribution.
