Traditional light emitting assemblies produce simple luminous effects, limiting their adaptability to various usage scenarios and atmospheres.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional light emitting assembly uses a fixed light emitting element and light transmission portion, then the structure is simple and reliable, but the luminous effect is too simple and lacks adaptability to different usage scenarios
Solution Approach 1:
The patent applies the dynamics principle by making the light transmission portion rotatable relative to the light emitting element. The driving portion enables the light transmission portion to rotate between different positions, dynamically changing the projection pattern without requiring multiple fixed components. This resolves the contradiction by providing pattern variety through motion rather than through complex static structures.
2Adaptability or versatility
If multiple light emitting elements are used to achieve multiple patterns, then the luminous effect is enriched, but the device complexity and failure rate increase
Solution Approach 1:
The patent applies the universality principle by designing a single light emitting element that can produce multiple projection patterns through the rotation of the light transmission portion. The light transmission portion acts as a multi-functional component that modifies the light beam to create different patterns (e.g., full light pattern, half light pattern, striped pattern) without requiring multiple separate light emitting elements, thus maintaining high reliability while providing pattern variety.
3Adaptability or versatility
If the light transmission portion is made movable to change patterns, then the luminous effect is enriched, but the device complexity increases
Solution Approach 1:
The patent applies the segmentation principle by dividing the light transmission portion into multiple independent light transmission areas (first light transmission area, second light transmission area, etc.). Each area can be selectively positioned in the light beam path through rotation, allowing pattern switching without requiring complex mechanical mechanisms. The segmentation of the light transmission portion into functional zones simplifies the overall structure while enabling versatile pattern generation.

AI summary
Disclosed are a light emitting assembly and a light emitting device. The light emitting device includes a first light emitting element, a first light transmission portion and a driving portion, The first light emitting element emits a first light beam. The driving portion can drive the first light emitting element or the first light transmission portion, such that a position relationship between the first light emitting element and the first light transmission portion is switchable between a first state and a second state. In the first state, the first light beam passing through the first light transmission portion presents a first pattern; in the second state, the first light beam passing through the first light transmission portion presents a second pattern which is different from the first pattern.
