LED LIGHT SOURCE AND MANUFACTURING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To solve a problem that when a contact angle of a resin end part is made close to 90 degrees for forming a transparent sealing resin into a shape close to a sphere with an LED chip located at the center thereof in an LED light source where the LED chip is mounted on a wiring board and the transparent sealing resin is dropped to seal the LED chip, it is necessary to significantly increase the viscosity of the resin and thus it takes a long time to drop the resin.SOLUTION: An LED light source 101 includes: an LED chip 1 mounted on a mounting surface 4a of a substrate 4; a ring member 3 disposed on the mounting surface 4a with a space formed between the mounting surface 4a and its outer periphery 3d so that the LED chip 1 is positioned in a circular through hole 3c; and a sealing resin 2 sealing the LED chip 1 so as not to protrude to the mounting surface 4 located at the outer side relative to the outer periphery 3d of the ring member 3 on the front surface side of the ring member 3 that includes a region of the through hole 3c.
