Title:
LIGHT IRRADIATING DEVICE AND WELDING METHOD
Document Type and Number:
WIPO Patent Application WO/2007/007766
Kind Code:
A1
Abstract:
To be able to obtain an optical output having a desired light intensity profile
suitable for such purposes as the expansion of a welding area without increasing
a light emission intensity more than necessary. Such a constitution is used that
output light beams from a plurality of output end faces (115) arranged on the output
surface (114) of a light source unit (122) are condensed to one light beam by a condensing
lens to be applied to an object of irradiation, and one light beam applied to the
object is allowed to have a desired light intensity profile by a combination of
positions at which respective output end faces (115) are disposed and the intensity
distribution of light beams output from the respective output end faces (115),
whereby a desired light intensity profile required for one output light beam
can be realized by setting the locations of the plurality of output end faces (115)
and setting or variably controlling the intensity distribution of respective
output end faces (115).
