Light radiation device for hardening of light-curing resins

摘要

Arrangement has at least one light source (1) and a power supply for the light source. The light source is a LED operating in the blue region of wavelengths between 390 and 520 nm. The power supply is in the form of batteries or accumulators. Several blue LED chips (2) can be mounted on a common substrate (6). Several light sources can be used and these can be bundled together. Several LEDs or LED chips with different wavelengths of e.g. 435, 450 and 470 nm. can be used.
