Title: LIGHT FIXTURE
Abstract:
A light fixture comprising a set of known LEDs which have different emission spectra in a range of the order of 400-800 nm and are equipped with drivers, is characterized in that from the known LEDs having different spectra, LEDs are selected which have emission spectra in a range of 443-650 nm, wherein the spectra of the selected LEDs overlap one another at different spectral sections of the range, preferably at a level of 0.5 of the maximum amplitude, wherein 5 types of LEDs each having a power of 10 W are used, including warm white, dark blue, light blue, green and full spectrum, wherein the drivers of the LEDs are capable of feeding energy thereto that amounts to 1.4, 0.3, 0.3, and 1.25, respectively, of the level of energy supplied to the full-spectrum LED. The invention provides a light fixture with an emission spectrum corresponding to sunlight while minimizing the total number of LEDs used.
