Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting solutions, particularly those using LEDs, face challenges in directing light effectively while avoiding glare and unwanted reflections, often requiring optical elements like lenses or reflectors that can be visually distracting.
Innovation Solution
A linear lamp design with open light emission openings on its underside, featuring pot-like reflectors that extend from each LED to the emission opening, allowing for controlled light distribution without optical closures, and a carrier element for efficient heat dissipation and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If optical elements like lenses or reflectors are used to direct light, then light distribution control is improved, but visual appeal and simplicity deteriorate
Solution Approach 1:
The patent removes traditional closed optical elements (lenses, covers) from the light emission openings, extracting the optical function to open space where light can emit directly while maintaining control through the pot-like reflector shape and positioning
Solution Approach 2:
Instead of closing the light emission openings with optical elements to control light, the patent inverts the approach by leaving openings open and using the pot-like reflector to shape light from below, creating a novel appearance while maintaining lighting control
2Illumination intensity
If individual optical elements are assigned to each LED, then light direction control is improved, but device complexity increases
Solution Approach 1:
The patent merges the optical control function into a single pot-like reflector structure that serves multiple LEDs simultaneously, rather than assigning individual optical elements to each LED, thereby reducing component assembly complexity while maintaining light direction control
Solution Approach 2:
The pot-like reflector structure serves multiple functions: it acts as an optical element for light direction control, a positioning element for aligning LEDs with emission openings, and a structural component that can be manufactured as a single integrated piece
3Illumination intensity
If light emission openings are closed with optical elements, then light emission control is improved, but heat dissipation efficiency deteriorates
Solution Approach 1:
The patent extracts the optical control function from closed elements and implements it through open light emission openings with pot-like reflectors, allowing heat to dissipate freely from the LED to the environment while maintaining light emission control
Solution Approach 2:
The patent uses a transparent or translucent cover only for indirect lighting areas, allowing heat to pass through freely while maintaining optical control, rather than using opaque closed elements that would trap heat
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
The design provides a visually appealing, efficient, and adaptable lighting solution that meets modern illumination requirements by ensuring reliable positioning and heat management, while minimizing component assembly complexity.
Implementation Method 1
A pot-like reflector is responsible for the emission of light, which is assigned to a light source and extends from the light source to the associated light emission opening
Implementation Method 2
the carrier element, as already mentioned, also serves to hold the light sources, this ensures that the heat generated during operation of the light sources, which are preferably implemented as LEDs, can be efficiently transferred to the housing and dissipated here to the environment
