摘要：
The present invention is concerned with a hair removal device for removal of red hairs that has a light emission unit having a substrate and a plurality of first LED dies emitting at a peak emission wavelength in a wavelength range of between about 480 nm and about 510 nm, the first LED dies being mounted on the substrate on an area in the range of between about 0.2 cm2 and about 100 cm2, wherein the hair removal device is arranged to emit a treatment light pulse by the first LED dies having a pulse length in the range of between about 30 ms and about 200 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 about 3 J/cm2 and about 6 J/cm2 is achieved by application of the treatment light pulse.
