Light-emitting Module Lens Support Diffusivity

Solution Overview

Problem

Existing light-emitting modules are difficult to assemble due to the need for precise placement of masking resins to conceal electronic components, which can lead to accidental contact with the light source and affect the module's aesthetic appearance.

Innovation Solution

A light-emitting module design that includes a substrate with a light source and electronic components, covered by a first light-transmissive member comprising a lens and a support with a higher light diffusivity than the lens, allowing for easier assembly and improved aesthetics by reducing the visual recognition of electronic components.

AI summary

A light-emitting module includes: a substrate; a light source disposed on the substrate; an electronic component disposed on the substrate and separated from the light source; and a first light-transmissive member including a first lens and a first support, and covering the light source and the electronic component, the first support supporting the first lens and including a light diffusing substance. A light diffusivity of the first support is higher than a light diffusivity of the first lens. The first lens overlaps the light source and the first support overlaps the electronic component in a top view.
