LED TYPE TIP OPTICAL ADAPTOR
Document Type and Number:
Japanese Patent JP2018138111
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an LED type tip optical adaptor which has achieved improvement in observation performance and assembly workability while preventing electric short-circuit generated by water infiltrating to an illumination substrate.SOLUTION: An LED type tip optical adaptor 5 includes: light emitting elements 10 for emitting illumination light; a three-dimensionally molded substrate 7 including a mounting surface 7c which has a through-hole 7h and on which the light emitting elements 10 are mounted, and wall surface parts 7d, 7e which are provided by protruding from the mounting surface 7c; an adaptor frame member 6 having a small diameter hole 6a on which an outer peripheral surface of a first wall surface part 7d of the three-dimensionally molded substrate 7 is arranged, and for forming a first adhesive agent filling space S1 for filling an adhesive agent 22 between the outer peripheral surface of the first wall surface part 7d and an inner peripheral surface of the small diameter hole 6a; and a lens holding frame 8 arranged in the through-hole 7h, and for forming a second adhesive agent filling space S2 for filling the adhesive agent 22 between the inner peripheral surface of the second wall surface part 7e and the inner peripheral surface of the through-hole 7h.SELECTED DRAWING: Figure 6E
