Tīmeklis2024. gada 15. jūl. · A conventional micro-LED device emission exhibits Lambertian distribution, and it requires stacking of multiple optical components into a 3D … The situation for a Lambertian surface (emitting or scattering) is illustrated in Figures 1 and 2. For conceptual clarity we will think in terms of photons rather than energy or luminous energy. The wedges in the circle each represent an equal angle dΩ, of an arbitrarily chosen size, and for a Lambertian surface, the number of photons per second emitted into each wedge is proportional to the area of the wedge.

TīmeklisA typical radiation field from a high-radiance red LED is shown to the right. The bright center spot is the main radiation field with an intensity half-width of about 15 degrees. Note that if the LED emitting source was a planar Lambertian emitter (perfectly diffuse source), the half-intensity angle would be 60 degrees (Lambert's cosine law).
