Solution Overview
Problem
Current lighting solutions for refrigerators and showcases, such as incandescent and fluorescent lamps, are prone to damage from moisture and have inadequate light distribution, leading to shortened lifespan and inefficient lighting.
Innovation Solution
An LED lamp design featuring a strip housing with a sealing end cover and embedded sealing member, allowing for a sealing cavity to be filled with sealant, providing enhanced waterproofing and a secondary light distribution lens for improved illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If ordinary light sources (incandescent lamps and fluorescent lamps) are used in refrigerators and showcases, then the lighting can illuminate the interior, but the energy consumption is high and there is no light-sweeping function resulting in inadequate lighting or shadows
Solution Approach 1:
The patent replaces traditional mechanical lighting systems (incandescent bulbs, fluorescent tubes) with LED lighting technology. This substitution provides lower energy consumption while maintaining adequate illumination intensity and adding light-sweeping functionality through programmable LED control
Solution Approach 2:
The patent changes the lighting parameters by using LED technology with adjustable brightness, color temperature, and dynamic lighting patterns. The lighting system can vary intensity and distribution to eliminate shadows and provide comprehensive illumination without high energy consumption
2Reliability
If lamps without waterproof sealing structures are installed in refrigerators or showcases, then the installation is simple, but the lamps are easily damaged by moisture and water vapor generated due to temperature difference, shortening the using life
Solution Approach 1:
The patent uses a nested sealing structure where the sealing ring is embedded within the connection between the lamp housing and end cap. This nested design provides effective waterproof sealing without adding external complexity, protecting the lamp from moisture while maintaining a compact integrated structure
Solution Approach 2:
The patent employs a flexible sealing ring (thin film structure) that creates a waterproof barrier between the lamp housing and end cap. This flexible sealing element effectively prevents moisture penetration while maintaining a simple overall device structure
3Reliability
If a sealing cavity is formed by spacing the sealing member and sealing end cover apart, then the sealant can be injected to improve waterproofing, but the structure becomes more complex
Solution Approach 1:
The patent incorporates a sealing cavity design that is pre-formed during the assembly process. The spacing between the sealing member and end cap creates the cavity in advance, allowing sealant to be injected through existing openings without requiring additional structural complexity or post-assembly modifications

AI summary
The present invention relates to an LED lamp comprising a strip housing having an inner cavity for accommodating a lamp body and at least at one end forming a opening for loading the lamp body; and a sealing end cover for sealing the opening; a sealing member is embedded in the opening, and the sealing member and the inner space of the opening have the same cross section perpendicular to the length direction of the strip housing; the sealing member and the sealing end cover are spaced apart to form a sealing cavity for injecting the sealant. the LED lamp of the invention on the one hand realizes the first waterproof protection of the end part by the sealing member, and on the other hand realizes the second waterproof protection through the sealant layer formed by pouring sealant between the sealing member and the sealing end cover, so the LED lamp has higher waterproof rating than the existing lamps and can be conveniently applied to a humid device such as refrigerator, refrigerator, freezer and vending machine.
