The illuminance at the centre of each of the areas is measured at desk-top height (typically 0.85 metres above floor level), and an average value of illuminance is calculated.
Keywords: Lambertian source,- illuminance, -luminance.
For example, an average degree of illuminance of 200 lx applies for the public hall.
General lighting installations typically provide an approximately uniform illuminance over the whole of the working plane.
Typical recommended level of maintained illuminance (lux)

Illumination given off a black light is similar to sunlight in that it is regarded as harmless to the eyes--unless you stare at the source without protection.
uniform illumination across the aperture
Bend lighting means a lighting function to provide enhanced illumination in bends.
The test pattern shall be evenly illuminated at an illumination of 3000 ± 300 Lx.

A 200-lux illumination is well appointed for this particular area.
SB units shall be so made as to give adequate illumination without dazzle for the passing beam, and good illumination for the driving beam.
The illuminance comparison device compares an illuminance at an arbitrary position with a target illuminance and the supplies the comparison result to the illumination devices.
Headlamps shall be so made that they give adequate illumination without dazzle when emitting the passing beam, and good illumination when emitting the driving beam.
Headlamps shall be so made that they give adequate illumination without dazzle when emitting the passing beam, and good illumination when emitting a driving beam.
A light assembly enables effective illumination of advertising.
HSB units shall be made so as to give adequate illumination without dazzle when emitting the passing beam and good illumination when emitting the driving beam.
An illumination device provides stable illumination for microscopic evaluations.
Punjab, the province in which the project is located, enjoys some of the highest solar irradiance in the world.
The second ratio is an irradiance at 310nm to the second total irradiance, wherein the second ratio is at least 1.2x10-3.
Solar Irradiation Study: solar data summaries and analysis (global horizontal irradiance - GHI and direct normal irradiance - DNI), determination of projected energy production.
total irradiance (thermal injury): calculated irradiance within the infrared wavelength range 780 nm to 3000 nm expressed in watts per square metre [W m-2]
With around 1,600 to 2,700 hours of sunlight per year and an average direct normal irradiance (DNI) of 4-5 kWh/m2, the country has huge potential for solar power.
When she – bright point of a point of brightness,
The brightness control varies the luminance of the display between the minimum luminance at a minimum illuminance to a maximum luminance at a maximum illuminance.
The unnecessary lighting of the night sky and environment is called light pollution.
Consequently, the lighting follows the temporal evolution of the frequency with which it has been associated, i.e. the lighting follows the rhythm of the sound signal being reproduced.
The lumen method of lighting design leads to an average horizontal plane illuminance on the working plane, and it is possible to use the method to establish average illuminance values on the walls and ceilings within an interior.
(12) Lighting shall be mounted not less than twenty feet above the ring floor and shall provide an intensity of at least 540 LUX over the total ring area.
In the alternative with inversion, operating entirely by lighting, the condenser (2) is suppressed.
All light sources were equated for illuminance of 2000 lux.
Pay special attention to the relationship between color temperature and illuminance
Method for calculating the average illuminance in a room using the , the utilisation factor and the luminous flux of the lamp.
Their asymmetrical very wide beam light distribution creates a degree of illuminance of about 50 lx.
This is achieved through good vertical and cylindrical illuminance.

The sun and the moon are what gives light upon the earth.
It turns to continuously follow the path of the sun to provide a constant supply of light to the second mirror.
This part of IEC 60904 describes procedures for the measurement of the current-voltage characteristics of multi-junction photovoltaic devices in natural or simulated sunlight.
That featureless glow of our nocturnal skies is called “light pollution.
