摘要：
The present invention is concerned with a hair removal device having a light emission unit having a substrate and a plurality of first LED dies that are mounted on the substrate on an area of at least 0.2 cm2, in particular of at least 1 cm2, the first LED dies having a peak emission wavelength in the far red or infrared wavelength range of between 700 nm and 980 nm, wherein the hair removal device is arranged to emit a treatment light pulse having a pulse length in the range of between 60 ms and 120 ms and the first LED dies have a radiant flux such that a radiant fluence on the skin of a user in the range of between 3 J/cm2 and 7 J/cm2 is achieved by application of the treatment light pulse.
