摘要

Study of the photometric and the colorimetric characteristics of the optical systems of LED domestic lamps is done in this paper. The results for the measured maximum luminous intensity, beam angle, distribution of the luminous fluxes in spatial zones and light distribution curves of the bare LEDs lamp and LED lamps with different optical systems are presented. The efficiency losses in the optical systems of the tested LED domestic lamps are shown. A conclusion in terms of the realized photometric indicators and achieved total efficiency of the LED lamp optical system with various diffuser materials is done. Comparative results of measured colorimetric parameters of tested LED lamps as dominant wavelength, color rendering index and correlated color temperature for bare LEDs and LED lamps with optical system are presented.
