1. A semiconductor light-emitting device comprising:

  • a base board having at least one pair of chip mounting portions;

    at least one semiconductor light-emitting chip located adjacent the base board and configured to emit light along an optical axis of the device;

    a reflector located adjacent the base board and the at least one semiconductor light-emitting chip, the reflector including an inner side surface configured to reflect light from the at least one semiconductor light emitting chip during operation of the at least one semiconductor light emitting chip, an outer peripheral side surface facing away from and opposed to the inner side surface, and a top surface located between the inner side surface and the outer peripheral side surface, the outer peripheral side surface being an outermost peripheral surface of the reflector in a radial direction away from the optical axis of the device;

    an encapsulating resin disposed in the reflector;

    an optical lens having a concave-shaped cavity including an inner corner surface and a plurality of convex portions located at the inner corner surface, the plurality of convex portions contacting the top surface of the reflector and configured to face the top surface of the reflector, and the optical lens being composed of a material having a first softness; and

    a spacer composed of a transparent resin that has a second softness that is softer than the first softness of the material of the optical lens, the spacer being located between the concave-shaped cavity of the optical lens and the top surface of the reflector, including spaces between each of the plurality of convex portions of the optical lens, the spacer extending along the top surface of the reflector and extending downward towards the base board and along at least a portion of the outer peripheral side surface.
