Solution Overview
Problem
The risk of accidental contact with high-voltage LED circuit boards in lighting modules is not adequately addressed in existing designs, posing a safety hazard.
Innovation Solution
A lighting module arrangement featuring a protective optical element designed as a profile body, integrated with the carrier element via snap-in connections and positioned to enclose the circuit board, preventing accidental detachment and providing secure protection without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the circuit board is exposed for electrical connection, then ease of assembly and maintenance is improved, but safety against accidental contact is worsened
Solution Approach 1:
The lighting module is divided into separable components: the circuit board assembly and the optical element. The optical element acts as a protective cover that can be detached for maintenance but provides safety during operation, resolving the contradiction between exposed connections and protection.
Solution Approach 2:
The optical element serves as an intermediary protective barrier between the high-voltage circuit board and users. It allows electrical connections to remain accessible while preventing direct contact with dangerous components.
2Object-affected harmful factors
If the optical element is securely fixed to prevent detachment, then safety is improved, but ease of maintenance is worsened
Solution Approach 1:
The fixation mechanism transitions from a permanently fixed state to a dynamically reversible state. Snap-in connections provide secure fixation during operation but can be easily released by applying lateral force, allowing the optical element to be removed for maintenance when needed.
Solution Approach 2:
The mechanical state of the optical element changes from locked (during operation) to unlocked (during maintenance). The snap-in connection design allows parameter change from a secure fixed position to a removable position through simple lateral displacement.
3Object-affected harmful factors
If additional protective components are added, then safety is improved, but device complexity is worsened
Solution Approach 1:
The optical element performs multiple functions simultaneously: it provides optical functionality for light emission/direction and serves as a protective safety cover. This eliminates the need for separate protective components, reducing device complexity while maintaining safety.
Solution Approach 2:
The protective function is merged with the optical element rather than being a separate component. The optical element is both the light-emitting component and the safety protection, combining two functions into one element.

AI summary
The invention relates to a light module arrangement for a light. Said light module arrangement comprises at least one LED (2) and at least one circuit board (4), the at least one LED (2) being arranged on the at least one circuit board (4). Said light module arrangement also comprises a support element (6) on which the at least one circuit board (4) is maintained and an optical element (8) for optically influencing light emitted by at least one LED (2). Said optical element (8) is embodied as a protection element for protecting the at least one circuit board (4) against contact. As a result, the at least one circuit board (4) and/or the at least one LED (2) is reliably protected against accidental contact, in particular without having to form an additional component, which can cause damage based on the high electrical tension.
