LED Light Bulb with Colored Light Pipe for Warm Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current energy-efficient light bulbs, such as LEDs and fluorescent bulbs, often fail to replicate the brightness and warm color temperature of traditional filament bulbs, and may not provide both ambient and focused lighting from a single source, requiring multiple bulbs and expensive installations for retrofitting in existing fixtures, which are also aesthetically unsatisfactory.
Innovation Solution
A light bulb design featuring an extruded transparent light pipe with colored lines embedded within, acting as a light conduit and diffuser, combined with an LED light source, allowing for both focused and ambient lighting from a single bulb, compatible with existing fixtures and customizable for aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If fluorescent or LED bulbs are used to replace traditional filament bulbs, then energy efficiency is improved, but brightness and warm color temperature are worsened
Solution Approach 1:
The light bulb divides lighting into two separate functions: an LED light source for energy-efficient ambient lighting and a light pipe with colored lines for focused warm light delivery, allowing each component to optimize its specific function
Solution Approach 2:
The light pipe acts as an intermediary component that receives light from the LED source and transforms it into focused beams with warm color temperature, mediating between the efficient but cold LED light and the desired warm focused illumination
2Adaptability or versatility
If multiple bulbs are used to provide both ambient and focused lighting, then lighting functionality is improved, but device complexity and installation cost are worsened
Solution Approach 1:
The invention merges ambient lighting and focused lighting functions into a single bulb by combining an LED light source with a light pipe, eliminating the need for multiple separate bulbs and simplifying installation
Solution Approach 2:
The single bulb design provides multiple lighting functions (ambient and focused) simultaneously, making it a universal solution that replaces multiple specialized bulbs with one multi-functional unit
3Illumination intensity
If halogen or LED bulbs are designed for specific fittings, then lighting performance is improved, but adaptability to existing fixtures is worsened
Solution Approach 1:
The bulb is designed with universal adaptability by incorporating standard screw or bayonet fittings, allowing it to function in various existing fixture types while maintaining its dual lighting performance capabilities
4Use of energy by moving object
If fluorescent bulbs are used for energy saving, then energy consumption is reduced, but aesthetic appeal and immediate brightness are worsened
Solution Approach 1:
The bulb segments the light output into immediate ambient light from the LED source and focused warm light from the light pipe, ensuring both energy efficiency and immediate aesthetic appeal are satisfied simultaneously

Implementation Method 1
a light pipe mounted to the light source; wherein the light pipe is an extruded transparent bar or tube having coloured lines extending along and within it
Implementation Method 2
a portion of the light from the light source is conveyed along the light pipe and out its distal end, while a portion of the light from the light source escapes through the sides of the light pipe
Implementation Method 3
the coloured lines are embedded in the light pipe, wherein each of said coloured lines extends substantially parallel to the lengthwise axis of the light pipe
Implementation Method 4
the light pipe is extruded with a coloured material and the lines are co-extruded with the light pipe

AI summary
This application describes herein a light bulb, in particular one which comprises a light pipe in the form of a bar or tube, mounted to a light source, wherein the light pipe has coloured lines extending along and within it. When illuminated by the light source, the light pipe acts as a means for dissipating light, providing the desirable effect of a traditional filament or incandescent bulb without the high temperatures and low energy efficiency associated with such a light source. Such a light bulb may also include a screw or bayonet fitting, allowing it to be retrofitted into existing lighting units, providing backwards compatibility with existing lighting installations.
