Solid state lighting components like LEDs, S2LEs and LASERs are typically made up of a semiconductor substrate with an “n doped” layer (one overflowing in electrons leaving some free) and a “p doped” layer (poor in electron content or rich in “holes” able to capture free electrons and which emit light when in contact with them, like positrons do) and sandwiched between the two layers is a layer of neutral substrate which on passing of a sufficient current, is the scene of the combination of the excess holes and electrons from the two doped layers with subsequent light emission, which follows Lambert’s law.
In photometrics, Lambert's cosine law says that the total radiant power observed from a "Lambertian" surface is directly proportional to the cosine of the angle between the observer's line of sight and the surface normal. It is named after Johann Heinrich Lambert, from his Photometria, published in 1760.
An important consequence of this law is that when an area element on the surface is viewed from any angle, it has the same radiance. This means, for example, that to the human eye it has the same apparent brightness (or luminance).
has patented and created a system capable of high performance high quality low cost lighting applications for illuminating roads and parks, shopping malls, swimming pools, stadia, car parks, gardens, factories, communities, discos and even cemetery lighting.
The agile driving of the light sources used allows for remote control and management.
