Down
- 2. The intensity of light emitted from a surface per unit area in a given direction (measured in cd/m²).
- 3. A device intended to limit the amount of current in an electric circuit, essential for gas-discharge lamps.
- 6. An effect where moving objects appear stationary or pulsed due to light modulation.
- 8. The process of varying the luminous flux of a light source by adjusting the electrical input.
- 10. RENDERING – The ability of a light source to reveal the colors of various objects faithfully (Acronym: CRI).
- 11. The angle between the two directions for which the intensity is 50% of the maximum intensity.
- 15. The technical term for a complete lighting unit, including the lamp and the parts designed to distribute the light.
- 16. An optical element that scatters light to provide softer illumination and reduce shadows.
