Solution Overview
Problem
Conventional light emitting modules have limited color selection and difficulty in uniformly arranging light emitting elements on curved or complex-shaped surfaces, which restricts their diversity and practicality, and hinders the thinning development of products.
Innovation Solution
A light emitting module comprising a working piece with a light emitting film that includes a bottom layer, a pattern layer, and a color layer, which together form a light emitting pattern with varying motifs and colors, eliminating the need for discrete light emitting elements and optical components, allowing for application on complex shapes and diverse appearances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If discrete light emitting elements are used to achieve diverse light emitting colors, then color diversity is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent merges multiple light emitting elements of different colors into a single integrated light emitting module. The module contains red, green, and blue light emitting elements arranged in a specific pattern, allowing diverse light emitting colors to be achieved through a single component rather than multiple separate elements, thereby reducing arrangement complexity while maintaining color diversity.
Solution Approach 2:
The light emitting module serves multiple functions simultaneously - it can emit red, green, and blue light individually and in combination to produce various colors. This multi-functionality eliminates the need for separate light emitting elements for different colors, simplifying the overall device structure while maintaining versatility in light emitting options.
2Area of stationary object
If discrete light emitting elements are arranged on curved or complicated surfaces, then light emission coverage is improved, but manufacturing precision and uniformity deteriorate
Solution Approach 1:
The light emitting module is segmented into multiple sub-regions with different light emitting elements arranged in specific patterns. This segmentation allows the module to be designed as a unified structure that can be precisely manufactured and then applied to curved or complicated surfaces, ensuring arrangement uniformity while achieving comprehensive light emitting coverage.
3Adaptability or versatility
If space is reserved for arranging discrete light emitting elements, then light emission functionality is improved, but product thickness increases
Solution Approach 1:
Multiple light emitting elements are merged into a single integrated module with compact internal arrangement. This merging reduces the overall space required compared to using separate discrete elements, allowing the product to maintain light emission functionality while reducing thickness.
Solution Approach 2:
The light emitting elements within the module are arranged in a nested or closely packed configuration, maximizing space utilization. This nesting approach allows all necessary light emitting components to be housed in a compact volume, reducing the space required and thereby decreasing product thickness while maintaining full light emission capability.

AI summary
A light emitting module including a working piece and a light emitting film is provided. The light emitting film is disposed on a surface of the working piece and emits lights according to a voltage difference. The light emitting film includes a bottom layer, a pattern layer and a colour layer. The bottom layer is disposed on the surface of the working piece. The pattern layer is disposed on the bottom layer for providing a pattern. The colour layer is disposed on the bottom layer for providing a colour. The pattern layer and the colour layer are overlapped with each other over the bottom layer, so that the light emitting film forms a light emitting pattern with the pattern and the colour on the working piece.
