摘要 |
<p>The purpose of the present invention is to manufacture, at low cost, a light emitting apparatus, which is configured of a light emitting element mounted on a substrate, said light emitting element being sealed by means of a translucent resin, and which has easily formed thereon a semispherical translucent resin, and has high light extraction efficiency, high light directivity, and less color unevenness. This light emitting apparatus is provided with: a light emitting surface (25), which has a light emitting element (10) mounted thereon; and a film (300) having a film rear surface (314), which covers a light emitting surface (25) at the circumference of the light emitting element (10), and a film front surface (313) and a film upper surface (315), which are on the reverse side of the film rear surface (314). The film (300) is provided with an edge section (310) that is provided with: a slope surface (311), which is formed in an annular shape such that the slope surface (311) surrounds the light emitting element (10), and that, toward the film rear surface (314) from the film upper surface (315), the diameter thereof is reduced and an angle formed with the film upper surface (315) is sharpened; and an edge (312), which is formed at the boundary between the film upper surface (315) and the slope surface (311). The light emitting apparatus is also provided with a translucent resin (40), which covers the light emitting element (10) and which is applied to the inside of the edge section (310).</p> |
