Abstract
A control system has been developed using LabView to analyze automotive light pollution in the environment. Some phenomena analyzed are irradiance, emission spectra, and optical power. The lights analyzed were halogen and LED. The study was carried out using an electronic circuit similar to cars' light control. The results obtained through the LabView platform indicated that the German halogen bulbs, the best sellers in Ecuador, do not have harmful irradiation as with LEDs; even so, they have exaggeratedly high powers, causing glare at night. For their part, LEDs have been shown to have low power but high light intensity at the wavelengths of 430nm or 450nm, in white and blue LEDs, respectively. These wavelengths cause various damages to the ecological system and health when the subject is exposed for long periods.
