Light Source Module Housing with Integrated Sealing Recess
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vapor proof lighting fixtures with traditional lamps and seals are prone to breakage, leading to shortened lifespan and exposure to environmental elements, and they are inefficient and have a short life span, making them unsuitable for demanding environments.
Innovation Solution
A light source module with a housing and a sealing material that encapsulates a solid-state light source, such as LEDs, within a globe, providing a secure and flexible seal to prevent environmental intrusion and protect against physical damage, allowing for retrofitting and improved energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a glass or plastic globe with a non-integrated seal is used to seal the lamp and electrical components, then the fixture can be used in problematic environments, but the globe is susceptible to being easily broken by accident or vandalism, exposing the lamp and electrical components to the environment
Solution Approach 1:
The invention divides the sealing function into two parts: the globe provides physical protection while a separate integrated seal at the base provides environmental sealing. This segmentation allows each component to optimize its function without compromising the other, solving the contradiction between protection and breakage resistance.
Solution Approach 2:
The invention uses composite construction combining the globe material (glass or plastic) with a separate seal material that has different properties optimized for sealing and durability. This composite approach allows the fixture to maintain both environmental protection and resistance to physical damage.
2Illumination intensity
If traditional lamps (A-lamp, HID, or fluorescent) are used, then the fixture can provide adequate illumination, but the lamps have a relatively short life span and are relatively inefficient light sources
Solution Approach 1:
The invention changes the fundamental parameter of the light source from traditional discharge or fluorescent lamps to LED technology. This parameter change results in dramatically improved lifespan and energy efficiency while maintaining adequate illumination intensity, directly resolving the contradiction between light output and duration of action.
3Reliability
If a separate non-integrated seal is used in the fixture, then the lamp and electrical components are sealed from environmental elements, but the seal does not provide adequate protection once the globe is broken
Solution Approach 1:
The invention segments the protection system so that the seal is integrated into the housing structure rather than relying solely on the globe. This creates a secondary containment system that remains effective even when the globe is compromised, solving the contradiction between initial sealing effectiveness and continued protection after breakage.
Solution Approach 2:
The integrated seal design provides a backup protection mechanism that is already in place before the globe breaks. This prior cushioning ensures that even if the primary protection (globe) fails, the secondary seal continues to protect the lamp and electrical components from environmental elements.
4Strength
If a globe is used to protect the light source, then the light source is protected from physical damage, but the globe is susceptible to being easily broken by accident or vandalism
Solution Approach 1:
The invention segments the protection function between the globe (providing physical barrier) and the integrated seal system (providing environmental containment). This allows the fixture to maintain physical protection while compensating for the globe's vulnerability through the redundant seal system.
Solution Approach 2:
The integrated seal provides a backup protection mechanism that is prepared in advance. When the globe breaks, this pre-positioned seal immediately activates to prevent environmental intrusion, effectively cushioning against the harmful effects of globe failure.

Data Source
AI summary
A light source module that includes a light source and a housing, the housing having a top portion for receiving the light source and an upper portion extending from the top portion to form a recess. A first sealing material provided inside the recess to form a seal that at least partially encapsulates the light source.
