Original Abstract
Experiment show results of the passage of almost parallel light rays, simulating the solar part of daylight, through skylights. Skylights were measured by using a cubic light integrator, a specially prepared spotlight and an automatic goniphotometer. The automatic goniophotometer with a modified-jogging moved with the spotlight. That trajectories around the cupola simulated trajectory of the sun in the sky. In sum measurement consisted of 18 variants of skylights. Except for the directional sensitivity of the skylight was also investigating the spectral reflection factor of seven materials intended for the manufacture of hollow light guide, which are commonly available on the Czech market. The results of the measurement show that the measured reflective materials proved a high integral reflection factor (min. 98,13 % to 99,82 %). In addition to the numerical results is in the work from which the article proceeded with, the evaluation graph, showing the directional sensitivity of the skylights.
