Method of manufacturing light emitting module, and light emitting module

Abstract

The present invention provides a light-emitting module provided with a light guide plate and a light-emitting element, the light-emitting module being made thinner and having little luminance unevenness. In the light emitting module, a dimming part is fixed on the bottom surface of a concave part of a second main surface which is arranged on the opposite side of a first main surface of a light emitting surface; a light-emitting element is bonded to the surface of the light-adjusting part, so that light emitted from the light-emitting element is emitted into the light guide plate through the dimming part, and the light guide plate radiates the emitted light from the first main surface to the outside; in the manufacturing method of the light-emitting module, as a light-emitting element unitin which a dimming part and a light-emitting element are joined and the dimming part and the light-emitting element are integrally formed, the dimming part of the light-emitting element unit is fixedin a concave part, and both the light-emitting element and the dimming part are fixed at a constant position of the light guide plate.

Description

technical field [0001] The invention relates to a manufacturing method of a light emitting module and the light emitting module. Background technique [0002] Light-emitting devices using light-emitting elements such as light-emitting diodes are widely used as various light sources such as backlights for liquid crystal displays and displays. [0003] For example, the light source device disclosed in Patent Document 1 includes a plurality of light-emitting elements mounted on a mounting substrate, a hemispherical lens member that seals each of the plurality of light-emitting elements, and a diffuser of light incident from the light-emitting elements disposed thereon. part. [0004] In addition, in the light-emitting device disclosed in Patent Document 2, a two-layer sheet in which a sealing resin layer and a phosphor layer are integrated is fixed on the upper surface of a light-emitting element, and its side surface is covered with a reflective resin.

Problems solved by technology

[0007] However, in the light source device as in Patent Document 1, the distance between the mounting substrate and the diffusion plate needs to be greater than the thickness of the lens member, and there is a possibility that sufficient thinning cannot be achieved.

In addition, in the light-emitting device of Patent Document 2, light from a plurality of light-emitting elements cannot be uniformly distributed and irradiated, and it cannot be used for applications requiring light-emitting characteristics with less unevenness in brightness.
