Solution Overview
Problem
Semiconductive light sources, such as LEDs, exhibit unidirectional light emission, limiting their suitability for decorative lighting applications where a more natural and aesthetically pleasing multi-directional light distribution is desired.
Innovation Solution
A decorative lighting device featuring a translucent post with strategically configured emission surfaces, including a center emission surface, a circumferential emission surface, and a radially-oriented emission surface, which propagate light from a semiconductive light source to create an incandescent visual effect by emitting light in multiple directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If semiconductive light sources (LEDs) are used for decorative lighting, then energy efficiency and longevity are improved, but light emission directionality is limited to unidirectional output
Solution Approach 1:
The translucent post is segmented into multiple emission surfaces (center emission surface, circumferential emission surface, and radially-oriented emission surface) that independently emit light in different directions. This segmentation allows the single LED light source to produce multi-directional light distribution, resolving the contradiction between energy efficiency of LEDs and the need for versatile light emission patterns.
Solution Approach 2:
The invention transitions from unidirectional light emission (one dimension) to multi-directional light emission by adding spatial dimensions through multiple emission surfaces oriented at different angles and positions. The circumferential emission surface emits light radially outward, the center emission surface emits light axially, and the radially-oriented emission surface emits light in intermediate directions, creating three-dimensional light distribution.
2Illumination intensity
If traditional incandescent bulbs are used to achieve natural light effect, then multi-directional light emission and aesthetic appeal are improved, but energy consumption increases
Solution Approach 1:
The translucent post acts as an intermediary between the energy-efficient LED light source and the desired incandescent visual effect. The post receives unidirectional light from the LED and redistributes it through multiple emission surfaces to create the appearance of natural incandescent lighting, thereby achieving the desired illumination effect while maintaining LED energy efficiency.
Solution Approach 2:
The invention creates a visual copy of incandescent light emission patterns using LED technology. By strategically positioning and orienting multiple emission surfaces on the translucent post, the system replicates the multi-directional light distribution characteristic of traditional incandescent bulbs, producing the same aesthetic effect without the high energy consumption.

AI summary
A decorative lighting device is presented and described. The device includes a translucent post configured to propagate light from an LED at a basal end along a linear axis to an apical end of the translucent post when in use, the translucent post comprising a center emission surface at the apical end on the linear axis configured to emit a center portion of light, a circumferential emission surface obliquely oriented relative to the linear axis between the LED and the center emission surface configured to emit a circumferential portion of the light, and a radially-oriented emission surface extending along the translucent post between the basal end and the circumferential emission surface configured to emit a radial portion of the light, wherein as light from the light is propagated through the translucent post, the radial, circumferential, and center portions of the light are emitted to create an incandescent visual effect.
