Polar curve lighting

Fortunately you can always rely on dmlights for assistance. In this article we will try to explain these . Luminaires and BZ Classification. Polar Curves for Indoor Direct Lighting.

Abstract - Light sources and technological luminaires development have led to the important changes in the luminaires luminous.

The higher the BZ label, the wider the light beam and the mounting spacing that would ensure correct uniformity.

Graphically, this information is compiled into polar formatted charts that indicate the intensity of light at each angle away from 0˚ lamp axis.

The numeric information is also available in tabular form. With floodlights, we specify the light distribution using Cartesian coordinates ( Fig. 2). The luminous intensity values . Information on how to read candlepower or light distribution curves that are provided by lamp and luminaire manufacturers. When the window is first opened the vertical plane and horizontal cone through the maximum . The contents of the graph can be user controlled using the More button.

When the curve is polar , the pole is at the point representing . More precise calculations can also be performed in DIALux, or similar calculation programs. Optionally, light -output ratios, spacing-to-height ratios, utilisation factors, and glare indices may be entered. For lamps the lamp description an optionally, lamp-lumen maintenance- factor curves are specified.

This tutorial shows you how to interpret LED Light Photometry Data. You can access our LED strip light test reports in the documentation tab of each product description page. These curves are generally represented in the coordinate system C-.

Photometric information which accompanies indoor lighting luminaires. Robust vandal and weather resistant fitting for non-cell prison applications. Suitable for wall or ceiling mounting.

Slim profile zinc coated steel body. This information is useful because it shows how much light is emitted in each direction and the relative proportions of downlighting and uplighting.
