Solution Overview

Problem

Existing diffused light projectors are limited in their ability to produce multiple fixed or moving beams of diffused light from a single light source, restricting their versatility in creating dynamic lighting effects.

Innovation Solution

Incorporating a prismatic lens with rotating and positionable facets between the light source and a Fresnel or plano-convex lens, allowing the light to be broken into multiple beams that can converge, diverge, and rotate, enabling various optical effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single light source with a reflector and diffuser is used, then the structure is simple and reliable, but only a single beam of diffused light can be produced

Engineering Contradiction:
Improvenumber of beams producedVSAvoidoptical system structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the single light beam into multiple beams by introducing a prismatic lens with multiple facets between the light source and diffuser. Each facet of the prismatic lens refracts the light at different angles, segmenting the original single beam into multiple separate beams that can be independently directed and diffused.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a prismatic lens as an intermediary optical element between the light source and the diffuser. This intermediary component modifies the light path by refraction, enabling the transformation from a single beam to multiple beams without fundamentally changing the basic projector structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the light beam is statically diffused through a fixed lens, then the optical path is simple, but dynamic lighting effects and beam movements cannot be achieved

Engineering Contradiction:
Improvebeam movement capabilityVSAvoidmechanical structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent converts the static optical system into a dynamic one by making the prismatic lens rotatable around the optical axis. This rotational capability allows the facets of the prismatic lens to change their orientation relative to the light source, enabling the generated beams to move and create dynamic lighting effects such as rotating patterns and changing beam directions.

Inventive Principle:
Principle #15Dynamics
