Solution Overview

Problem

Conventional cyc lighting devices often fail to provide a smooth, even light wash over large areas like cycloramas, as they lack effective diffusing mechanisms to ensure uniform coverage and efficient light distribution.

Innovation Solution

A light-diffusing attachment for a light engine, comprising a frame, a refracting lens, and a diffuser, which can be easily secured to the light engine, utilizing lenticular or cylindrical lenses to spread the light beam vertically and horizontally, and a diffuser to smooth out non-uniformities, allowing for quick conversion of the luminaire into a cyc light.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If conventional cyc lighting devices are used, then the lighting setup is simple, but the light wash is uneven and lacks smooth coverage over large areas

Engineering Contradiction:
Improvelight wash uniformityVSAvoidlighting device structure
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The lighting device is divided into separate functional modules: a light engine, a frame structure, a refracting lens assembly, and a diffuser assembly. This segmentation allows each component to be optimized independently while working together to achieve uniform light wash coverage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A refracting lens is introduced as an intermediary component between the light engine and the diffuser. The lens refracts and distributes the light beam, while the diffuser further scatters it to create a smooth, even light wash, together solving the uniformity problem.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Illumination intensity

If a refracting lens and diffuser assembly are added to the light engine, then the light wash becomes smooth and even, but the device complexity increases

Engineering Contradiction:
Improvelight coverage uniformityVSAvoidattachment structure
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The frame structure serves multiple functions: it provides mechanical support for the refracting lens and diffuser assembly, secures the attachment to the light engine housing, and positions the optical components correctly. This multi-functionality reduces the need for additional separate components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The refracting lens and diffuser are nested within the same attachment housing, with the lens positioned closer to the light engine and the diffuser positioned to receive light from the lens. This nested arrangement optimizes space and reduces overall device complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If the attachment is designed for quick conversion of the luminaire into a cyc light, then the ease of operation improves, but the manufacturing precision requirements increase

Engineering Contradiction:
Improveconversion speedVSAvoidattachment alignment
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The refracting lens and diffuser are pre-assembled and pre-positioned on the attachment frame during manufacturing. This preliminary assembly ensures correct alignment and positioning, so that when the attachment is quickly installed on the light engine, the optical components are already correctly positioned, reducing the need for precise manual alignment during operation.

Inventive Principle:
Principle #10Preliminary action
