Zusammenfassung: | The light (1) has an inner area (4) surrounded by a housing (2) and a cover disk (3), and super-absorbing polymer (15) arranged in the inner area, where the polymer regeneratively delivers and retains moisture. The polymer retains relative air moisture in the inner area at a constant value that is preset by a structure of the polymer, where the polymer is made of partially neutralized polyacrylic acid. The polymer contains sodium ions bonded in polymer particles, and an illuminant (5) with a LED chip (9) is arranged in the inner area. |
