OLED Illuminant Rear Connection Device for Modular Lamp Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing planar lamps with semiconductor lighting elements, such as LEDs and OLEDs, face challenges in accurate alignment and easy mounting/replacement, particularly when multiple units are arranged in rows or columns, and lack effective protection against accidental electrical contact.
Innovation Solution
A planar semiconductor lighting element is integrated into a carrier element with a plate-like or foil-like form, housed in an electrically insulating enclosure with a rear connection device that allows for easy mechanical and electrical connection to a socket, providing protection against accidental contact and enabling simple orientation and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If bracket-shaped sockets enclosing the substrate are used, then mechanical connection is achieved, but the illuminant must be inserted from one side making replacement laborious and time-consuming
Solution Approach 1:
The connection device is divided into separate functional elements: a connection element on the illuminant and a corresponding socket element. This segmentation allows the illuminant to be connected and disconnected independently without requiring complex bracket structures, enabling easy replacement from either side while maintaining secure mechanical connection.
2Manufacturing precision
If substrates are connected to sockets with electrical conductors, then electrical contact is established, but exact alignment on a common plane cannot be accomplished with desired accuracy
Solution Approach 1:
The connection device incorporates self-aligning features where the connection element and socket element automatically position themselves relative to each other during insertion. This self-service mechanism ensures exact alignment on a common plane without requiring complex external alignment structures or procedures.
3Object-affected harmful factors
If the illuminant housing completely encloses the carrier element, then protection against accidental contact is provided, but the connection device must be accessible creating potential exposure
Solution Approach 1:
The connection device is nested within the illuminant housing structure, with the connection element positioned such that it becomes accessible only when the illuminant is properly mounted in the socket. The housing encloses the carrier element for protection while the connection element extends or opens to allow connection access during installation and maintenance.

AI summary
The invention relates to an illuminant (23) and a socket (20) for a lamp (15). The features of the socket (20) can be implemented also independently of the features of the illuminant (23). The illuminant (23) has a preferably planar illumination surface (24). One or more semiconductor lighting elements are arranged within an illuminant housing (30). The illuminant connection device (70) required for mechanical and electrical connection to the socket (20) is provided on the rear face (66) of the illuminant (23), said rear face (66) lying opposite the illumination surface (24). The dimensions of the illuminant are preferably greater than the dimensions of the socket (10) such that the illuminant (23) fully covers the socket when looking onto the illumination surface (24), resulting in a particularly appealing look. Said socket and illuminant (23) modularly achieve large total illumination surfaces in a lamp (15) and an appealing overall appearance in a very simple manner.
