SSL Lamp With Crossing Elongated Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Solid-state lighting (SSL) lamps lack the warm, omnidirectional light distribution and decorative appeal of traditional incandescent lamps, making them less suitable for decorative applications, especially when used with transparent bulbs, due to their bright and directional light emission.
Innovation Solution
The design of SSL lamps featuring three or more elongated light emitting structures arranged to form a common neck at a minimum angle of 30 degrees, creating a sparkling effect and mimicking the light distribution of traditional incandescent lamps, which reduces glare and enhances decorative appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If SSL lamps use traditional directional light emitting structures, then energy efficiency is improved, but light distribution becomes less attractive and glary
Solution Approach 1:
The patent divides the light emitting structure into multiple elongated light emitting structures (at least three) that are arranged to cross each other, forming multiple light emitting points along the bulb. This segmentation allows the light to be emitted from multiple locations rather than a single directional source, distributing the light more evenly and reducing glare while maintaining energy efficiency.
2Use of energy by stationary object
If SSL lamps emit bright directional light, then energy consumption is reduced, but appearance and decorative appeal deteriorate
Solution Approach 1:
The patent transitions from a single-point directional light source to a distributed light emitting structure where multiple elongated light emitting structures cross each other at different angles. This creates a three-dimensional light distribution pattern that mimics the omnidirectional appearance of traditional incandescent lamps, improving decorative appeal while maintaining low energy consumption.
3Ease of operation
If SSL lamps use transparent bulbs for decorative viewing, then visibility is improved, but glary nature becomes more pronounced
Solution Approach 1:
By segmenting the light emission into multiple points along the transparent bulb through crossing elongated structures, the patent reduces the intensity concentration at any single location. This distributed emission pattern reduces glare for viewers while maintaining transparency and visibility, allowing the bulb to be viewed directly without causing eye strain.
4Shape
If SSL lamps aim to mimic traditional incandescent appearance, then decorative appeal is improved, but light distribution becomes less efficient
Solution Approach 1:
The patent merges multiple elongated light emitting structures that cross each other to form a unified light emitting system. This combination of multiple structures working together creates an omnidirectional light distribution pattern similar to traditional incandescent lamps, achieving both decorative appeal and energy efficiency by utilizing solid-state lighting technology.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design achieves an even light distribution and a sparkling effect, making the SSL lamps more attractive and suitable for decorative applications while reducing glare, thus overcoming the limitations of traditional SSL lamps in terms of appearance and usage.
Implementation Method 1
SSL lamps are constantly receiving more and more attention due to the low energy consumption compared to traditional incandescent light sources. Typical examples of SSL lamps are light sources based on different types of light emitting diodes, LEDs.

AI summary
The present invention relates to a SSL lamp (100) comprising: three or more elongated light emitting structures (102, 104, 106, 108). A respective first end (102a, 104a, 106a, 108a) of each of the three or more elongated light emitting structures (102, 104, 106, 108) are arranged such that they define a first polygon (150). A portion of each of the three or more elongated light emitting structures (102, 104, 106, 108) are arranged in vicinity of each other such that the three or more elongated light emitting structures (102, 104, 106, 108) crosses each other at a smallest angle (α, α') of at least 30 degrees, thereby forming a common neck (120).
