Moreover, what is vertical illuminance?
The vertical measurement is know as the vertical illuminance and is the amount of light that lands on a vertical surface, such as a wall. It is important to consider both vertical and horizontal illuminances in your lighting design.
Beside above, what is light illuminance? In photometry, illuminance is the total luminous flux incident on a surface, per unit area. It is a measure of how much the incident light illuminates the surface, wavelength-weighted by the luminosity function to correlate with human brightness perception.
Beside this, what is horizontal illuminance?
The closer to a light source the illuminated area is, the higher the Illuminance value. Horizontal illuminance describes the amount of light landing on a horizontal surface, such a desk, and vertical illuminance describes the illuminance landing on a vertical surface, such as a wall.
What is uniformity ratio in lighting?
Uniformity is the ratio of the minimum lighting level to the average lighting level in a specified area. It's a quality parameter for the overall illuminance distribution.
