Abstract: A lens for light emitting lamps that use light emitting elements such as LEDs, etc., is provided. The lens has a specific surface shape for light-distribution control to achieve desired light distributions, as well as a light emitting device using said lens. On the lens surface of the light emitting side which has a double-peak shape to obtain a light distribution characteristic having long and short two axes, by possessing a straight-line part in the surface shape of the light emitting side viewed on the lens short-axis cross section, a desired smoothly-diffused light distribution having a longitudinal direction with a certain width is obtained. The lens may be designed to have a surface of the light emitting side comprising a collection of straight lines parallel to the lens short-axis cross section, or to have a continuous curved surface comprising a collection of straight lines parallel to the lens short axis.

Abstract: Provided is a light emitting device in which deterioration of the substrate member can be reduced. The light emitting device includes a base member mainly made of a resin, a plurality of wiring portions and arranged on the base member via an adhesive agent, a groove portion defined between adjacent wiring portions, and at least one light emitting element which is disposed straddling at least a part of the groove portion. The adhesive agent is applied covering the base member from the groove portion, and contains a light-shielding member. The light-shielding member shields the base member from light, for example at a specific wavelength, emitted from the at least one light emitting element.
