摘要： In a lens-mounted light emitting unit comprising LED elements of multiple light colors, narrow-angle light distribution is enabled, and color mixing properties are improved. The lens-mounted light emitting unit 10 comprises LED elements 12 (12A to 12D) of multiple light colors placed on a base plate 11, and a lens unit 11 having a shape of a body of revolution to color-mix and emit the light from the LED elements 12. Assuming an arbitrary contact point P1 between the side incident surface 14c and the upper incident surface 14d of the lens unit 13, and that light from an LED element 12A farthest from the contact point P1 is refracted at the contact point P1 to form a light path L1 intersecting the emitting surface 14a at an intersection point P2, the emitting surface 14a inside a circle C1 formed by continuously connecting such intersection points has a diffusion angle larger than the diffusion angle of the emitting surface 14a outside the circle C1. This enables narrow-angle light distribution, and makes it possible to improve color mixing properties.

摘要： A light emitting device comprises: an LED chip mounted in a recess formed in a mounting substrate; a wavelength converting member that is disposed so as to cover the recess and the edge area around the recess and that is excited by light emitted from the LED chip to emit light of a wavelength different from an excitation wavelength; and an emission control member disposed at a light output side of the wavelength converting member so as to allow emission of light coming from an area of the wavelength converting member that corresponds to the recess and to prevent emission of light coming from an area of the wavelength converting member that corresponds to the edge area around the recess. This can prevent variations in color between light emitted from the central part of the wavelength converting member and light emitted from the part of the wavelength converting member that is located on the edge area around the recess of the mounting substrate, thereby reducing unevenness of color on the irradiation surface.
