FIELD: physics.SUBSTANCE: invention relates to GLS-look-alike LED light source (100) comprising two different types of LEDs (21, 22), preferably LEDs emitting with a near UV spectrum and a blue or white spectrum, respectively. The light source (100) also preferably comprises a transparent bulb (40) with a shape similar to an incandescent lamp that is coated by a luminescent layer (30) to achieve a white lamp spectrum. The red luminescent layer contains a composition which emits in the 600-800 nm range.EFFECT: lamp provides a full emission spectrum and high uniformity of luminescence of white light.13 cl, 6 dwg |
