Lamp Housing Integral Profiling for Springless Cover Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting devices with lamp housings require expensive mounting springs for attaching lamp covers, which are costly and require separate installation steps.
Innovation Solution
A lamp device design featuring a lamp housing with integral profiling that allows the lamp cover to be mounted without additional mounting elements, using a compressive force for attachment and a tool for removal, with flexible wall and support element profiles for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mounting springs are used to attach the lamp cover to the lamp housing, then the lamp cover can be securely fastened, but the production cost increases and additional assembly steps are required
Solution Approach 1:
The mounting function is merged into the lamp housing structure itself through the profiling (embossing) formed integrally with the wall. This eliminates the need for separate mounting springs or additional mounting elements, as the housing structure directly provides the attachment mechanism for the lamp cover.
Solution Approach 2:
The lamp housing structure serves its own mounting function through the integrally formed profiling. The embossing in the wall creates the attachment feature without requiring external mounting components, allowing the housing to attach the lamp cover using its own structural features.
2Reliability
If mounting springs are used to attach the lamp cover, then the lamp cover can be fastened to the lamp housing, but the number of assembly operations increases
Solution Approach 1:
The mounting function is combined with the lamp housing structure through the integrally formed profiling. This eliminates separate mounting elements and reduces the number of assembly operations required to attach the lamp cover to the housing.
3Reliability
If additional mounting elements are used, then the lamp cover can be attached, but the device complexity and production cost increase
Solution Approach 1:
The mounting function is merged into the lamp housing structure itself through the profiling. This eliminates the need for separate mounting elements or additional components, reducing device complexity while maintaining secure attachment capability.
Solution Approach 2:
The lamp housing structure provides its own mounting capability through the integrally formed profiling, eliminating the need for external mounting elements and reducing the total component count.
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 solution enables cost-effective production by eliminating the need for expensive springs, allowing for easy and secure attachment of the lamp cover using integral profiling and flexible materials, ensuring a defined position and easy removal.
Implementation Method 1
The second profiling engages behind the first profiling when the lamp cover is in place... the first profiling being formed as an embossing in a lamp housing made at least partially of sheet metal
Implementation Method 2
flexible wall and support element profiles for secure engagement

AI summary
The invention relates to a lamp device (10), comprising: a lamp housing (20) having an interior (I) for accommodating lighting means, wherein the lamp housing (20) has an opening (O) at one end, has a carrier plate (21) at a further end opposite the opening (O), and comprises a wall (22) that extends away from the carrier plate, which wall defines the opening (O) of the lamp housing (20) and bounds the interior (I) of the lamp housing (20) together with the carrier plate (21); and a lamp cover (50) for covering the opening (O) in an installed state, wherein the lamp cover (50) has an emission surface (51) and a supporting element (52), which is connected to the emission surface (51) and extends in the direction of the interior (I) of the lamp housing (20) in the installed state. According to a first aspect, the wall (22) of the lamp housing (20) has a first profile (31, 41) formed integrally with the wall (22), which first profile protrudes toward the interior of the lamp housing (20), wherein the supporting element (52) has a second profile (63, 73) that corresponds to the first profile (31, 41), and wherein in the installed state of the lamp cover (50), the second profile (63, 73) engages behind the first profile (31, 41), as viewed perpendicularly to the opening (O), on a side of the first profile (31, 41) facing the carrier plate (21). According to a second aspect, the wall (22) of the lamp housing (20) has a first profile (31, 41) formed integrally with the wall (22), which first profile protrudes away from the interior of the lamp housing (20), wherein the supporting element (52) has a second profile (63, 73) that corresponds to the first profile (31, 41), and wherein in the installed state of the lamp cover (50), the first profile (31, 41) engages behind the second profile (63, 73), as viewed perpendicularly to the opening (O), on a side of the second profile (63, 73) facing away from the carrier plate (21). The invention further relates to a lamp system, comprising a lamp device (10) according to the invention having at least one lighting means, which lighting means is provided on the side of the carrier plate (21) facing the interior (I).
