Respective lens array(s) may be provided with plurality or pluralities of lenses opposing LED cell(s). Light irradiated from LED cell(s) is, by action of respective lens(es) of first lens array(s), separately collected and is thereafter, by action of respective lens(es) of second lens array(s), separately magnified; and light exiting therefrom is combined in mutually superposed fashion at irradiation surface(s). Furthermore, respective LED cell(s) is/are made to undergo timed lighting by color.
