Jaké jsou principy technologie LED osvětlení?

LED light with one, brightness and illumination

The above two characteristics refer to the relation between the fluctuation of light, or the relation between the function of the space through which light propagates and the thickness through which it penetrates. The brightness and illumination are calculated by beer Lambert law, which can identify the change of light intensity according to the distance of light propagation in transparent environment.

LED light with two, the glory of the sky

The radiance of the sky is just the light that naturally shines on us at a given moment. We collected that the brightness is continuous in any process.

LED light band III. luminous factor

We must also consider the luminous factor. It reflects the relationship between the light intensity level scattered in one direction and the apparent surface of the light source in the same given direction. The factor is expressed as candela per square meter (CD / m2).

LED light with four, strong light

Strong light can make us blind. It may be caused by hot, inconsistent, or even poorly projected light sources. The amount of glare directly from the lighting equipment is calculated using UGR method (uniform glare level). It measures the discomfort caused by glare according to the brightness of the background. Levels can range from 10 to 30. The latter number determines the highest glare level.
