Bulbo 57 Lamp
Achille & Pier Giacomo Castiglioni, 2019
Blown borosilicate lighting fixture that allows to have a remarkable impact resistance and excellent transparency thanks to its low thickness. The LED filament is held in position by a molybdenum structure incorporated by a cannula, also in borosilicate, which in turn extracts the air and avoids internal condensation. The filaments carrying the mains voltage are housed in a cable gland, to meet the requirements of standard safety regulations. The light source is a flexible filament of micro-LEDs 225 mm long at mains voltage which, thanks to customized electronics, allows, with the most common triac dimmers, the management of the luminous flux which is 210 - 450 lumens. The light temperature at 2200 ° K was desired with the intention of replicating that of traditional incandescence. As well as the high CRI (equal to 95), which guarantees a high quality standard of color rendering.
