[Summary] [Object] In a light emitting device using a solid-state light emitting element (LED), to be able to broaden light distribution of exit light, easily control the light distribution, and make it difficult for light unevenness to occur. [Means for Settlement] A light emitting device 1 is provided with: an LED 2; and a wavelength converting member 4 that is adapted to contain a phosphor in a transparent resin member that covers an emission surface of the LED 2. The wavelength converting member 4 is, in a vertical cross-sectional view, formed so as to have an upward thickness thicker than a thickness in a lateral direction of the LED 2 and also have an apex part 40 in a light lead-out direction of the LED 2. According to such a configuration, in the vertical cross-sectional view of the wavelength converting member 4, an amount of light traveling in the lateral direction of the LED 2 is larger than an amount of light traveling upward, so that a light distribution curve becomes a so-called batwing type, and therefore light distribution can be broadened. Also, an amount of light traveling toward a reflector 8 in the lateral direction is increased to therefore make it easy to control the light distribution. Further, directionality is reduced, and therefore when the light emitting device 1 is incorporated in an illumination device 10, light unevenness can be made difficult to occur. |
