Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illumination devices face challenges in heat management and optical properties, often resulting in uneven brightness distribution and aesthetic issues due to compartmental designs that obstruct light and require additional components for heat transfer.
Innovation Solution
An illumination device with a thermally conducting carrier and envelope formed as a single integrated part, using ceramic materials for efficient heat transfer and omnidirectional light distribution, eliminating the need for separate components and seams that can obstruct light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a carrier divides the envelope into multiple compartments to support the light source, then heat transfer is improved, but light distribution becomes uneven and aesthetic appearance deteriorates
Solution Approach 1:
The patent merges the carrier and envelope into a single integrated component made of thermally conducting material. This eliminates the compartment division that caused uneven light distribution while maintaining effective heat transfer from the light source to the envelope surface, resolving the contradiction between heat management and optical uniformity.
2Temperature
If separate components are used for heat transfer, then heat management is achieved, but device complexity increases and assembly becomes more difficult
Solution Approach 1:
The invention combines multiple functions (light source support, heat conduction, and envelope structure) into a single integrated component. This eliminates the need for separate heat sink components and adhesive attachments, reducing device complexity and assembly steps while maintaining effective heat evacuation.
3Ease of manufacture
If adhesive is used to attach the cover to the heat sink, then assembly is simplified, but heat transfer efficiency is reduced and reliability deteriorates
Solution Approach 1:
By integrating the carrier and envelope as a single component, the invention eliminates the need for adhesive attachment entirely. This removes the thermal barrier introduced by adhesive layers while maintaining structural integrity, simultaneously preserving heat transfer efficiency and simplifying manufacturing.
4Temperature
If multiple compartments are created within the envelope, then heat management is improved, but optical obstructions occur and light distribution becomes inadequate
Solution Approach 1:
The patent creates a unified single-compartment design where the integrated carrier-envelope structure provides heat transfer pathways without creating internal partitions. This allows light to distribute uniformly in all directions from the central light source while heat is conducted through the thermally conducting material to the envelope surface.

AI summary
An illumination device comprising a light source (110). The illumination device comprises a thermally conducting carrier (130) arranged to support the light source. Furthermore, the illumination device comprises an envelope (120),wherein the carrier and the envelope together form a single compartment (140) at least partially enclosing the light source. The carrier is arranged to transfer heat (160) away from the light source to the envelope, and the envelope is arranged to dissipate heat (170) away from the illumination device. The carrier and the envelope of the illumination device may further form a single integrated part.
