luminous efficiency meaning in Hindi

Examples

1. For example, a typical incandescent light bulb has a luminous efficiency of only about 2 %.
2. Because most people have a point of maximum luminous efficiency that is off-center, the antagonistic chromostereoptic effects.
3. Multiplying radiance by luminous efficiency : the planet night's side is 1000 times dimmer than HD's photosphere.
4. Two very similar measurement systems were created to bridge the scotopic and photopic luminous efficiency functions, creating a unified system of photometry.
5. The Eagle also featured new technology to improve luminous efficiency of its headlamp system, afford greater styling freedom, and having a rectangular frontal aspect.
6. The "'luminosity function "'or "'luminous efficiency function "'describes the average spectral sensitivity of human visual perception of brightness.
7. The integrals of the XYZ color matching functions must all be equal by requirement 3 above, and this is set by the integral of the photopic luminous efficiency function by requirement 2 above.
8. All test methods specify that measurements should be made with visible light according to CIE spectral luminous efficiency function V ( ? ) in the CIE 1931 standard observer and CIE standard illuminant C.
9. The ASTM Method states that the illumination should be defined such that the source-detector combination is spectrally corrected to give the CIE luminous efficiency, V ( ? ), with CIE illuminant SC.
10. There are many non-incandescent light sources, such as the fluorescent lamp, high-intensity discharge lamps and LED lamps, which have higher luminous efficiency, and some have been designed to be retrofitted in fixtures for incandescent lights.
