Light-based hair removal device and cosmetic hair removal method

摘要

The present disclosure relates to a light-based hair removal device for at least temporary hair removal, the light-based hair removal device comprising an array of light emitting elements having at least two subgroups of light emitting elements, in particular semiconductor light emitting elements such as LEDs. A light emitting unit having, each of the sub-groups of light-emitting elements comprises at least one individual light-emitting element, the sub-groups of light-emitting elements being arranged for separate energy supply, and the light-emitting unit and the light-emitting unit are semi-continuously light A controller unit arranged to supply energy to sub-groups of light-emitting elements according to the energy-supplying sequence to emit, wherein the energy-supplying sequence has successive sub-sequences, each having at least once each of the sub-groups of light-emitting elements, at least One subgroup supplies energy at any given time instant And the energy supply sequence is such that the energy-free gap is at least one energy-free gap, with a length such that the energy-free gap is in the range of 1 μs to 4000 μs, in particular, so that the energy-free gap is not noticed by human observers. Includes units.
