Problems solved by technology

However, the energy of the light that is repeatedly reflected and passes through the wavelength conversion layer 15 multiple times is absorbed, and the intensity of the reflected light is attenuated.
[0013] As described above, in conventional light emitting devices, it is difficult to increase the intensity and brightness of emitted light from the light emitting device.

Abstract

The invention provides a light-emitting device which is equipped with: a light-emitting element (3); a matrix (1) which is equipped with a placement part (1a) for placing the light-emitting element (3) on the upper main surface; a first frame-shaped reflective component (2) which is formed on the upper main surface of the matrix (1) according to a way of surrounding the placement part (1a); a second frame-shaped reflective component (4) which is formed on the upper main surface of the matrix (1) according to a way of surrounding the first reflective component (2); a light transmittance component (6) which is arranged on the inner lateral of the second reflective component (4) according to a way of covering the light-emitting element (3) and the first reflective component (2); a first wavelength conversion layer (5) which is arranged in the inside of the light transmittance component (6) on the upper part of the light-emitting element (3) with intervals to the first and the second reflective components (2, 4) and converts the wavelength of lights that are sent out from the light-emitting element (3).

Description

technical field [0001] The present invention relates to a light-emitting device incorporating a light-emitting element and a lighting device using the light-emitting device. Background technique [0002] Figure 15 shows a conventional light-emitting device. Figure 15 Among them, the light-emitting device is mainly composed of a substrate 11 , a frame-shaped reflective member 12 , a light-emitting element 13 , a wavelength conversion layer 15 , and a light-transmitting member 16 . The substrate 11 is made of an insulator, and has a placement part 11a for placing the light-emitting element 13 in the central part of the upper surface, and is formed with a lead terminal and a metallization arrangement that electrically connects the inside and outside of the light-emitting device from the placement part 11a and its periphery. Wiring conductors (not shown) composed of wires and the like. The frame-shaped reflective member 12 is adhesively fixed on the upper surface of the base ...
