DIRECTLY VISIBLE LIGHTING DEVICE BASED ON LED (LIGHT EMITTING DIODE) WITH HOMOGENEOUS EXTERNAL LIGHTNING

摘要

FIELD: lighting.;SUBSTANCE: LED lighting device (10) comprises a housing with an opening (20) for the light output, a reflecting inner surface (23,25,27,29), a coating diffusing lens (30) at the opening (20) for the light output and a plurality of optical elements (50) configured to redirect light output from the plurality of LEDs (40) arranged in the LED lighting device (10). LEDs (40) are arranged in two rows parallel to each other, wherein the first row LEDs (40) are offset relative to the second row LEDs in a direction along the said first and second longitudinally extending rows.;EFFECT: formation of uniform brightness and colour of light.;20 cl, 8 dwg
