Abstract
The lighting device () includes an LED chip (), a mounting substrate () mounting thereto the LED chip, an encapsulation member () made of an encapsulating resin material for encapsulation of the LED chip, and a lens () made of a transparent resin material. The lens () is provided in its bottom with a recess () and is secured to the mounting substrate () with the encapsulation member () disposed within the recess (). The encapsulation member () is confined within the recess of the lens of the transparent resin material, which minimizes a difference in the coefficient of linear expansion between the encapsulation member and the surroundings for restraining occurrence of voids in the encapsulation member at a low temperature.
