Separable LED Light Source Module for Replaceable Emitters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
LED light source products, such as LED recessed lights and LED bulbs, require replacement of the entire unit when the LED chip or power module is damaged, leading to inefficiency and environmental pollution due to the non-detachable design.
Innovation Solution
A holder-and-emitting-member-separable light source module that allows for the replacement of only the damaged LED chips or power module by detachably connecting a light-emitting member to a light source holder, which includes a heat dissipation component, power contact, and circuit contact, with a push switch controlling the electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If LED light source products use a non-detachable one-piece design, then the structural integrity and simplicity are improved, but the ease of repair deteriorates
Solution Approach 1:
The LED light source module is divided into two separable parts: a light source holder (containing heat dissipation component, power contact, circuit contact, and push switch) and a light-emitting member (containing LED chips, light circuit board, and power management module). This segmentation allows the light-emitting member to be replaced independently when damaged, while the holder can be reused, thereby improving ease of repair without compromising structural integrity when assembled.
2Reliability
If the entire LED light source must be replaced when components are damaged, then reliability is improved, but loss of substance deteriorates
Solution Approach 1:
When the light-emitting member becomes damaged, only this component is discarded and replaced, while the light source holder (including the durable heat dissipation component, power contact, circuit contact, and push switch) is recovered and reused. This approach maintains system reliability by ensuring proper replacement of faulty components while significantly reducing material waste compared to replacing the entire light source.
3Reliability
If the entire LED light source must be replaced when components are damaged, then reliability is improved, but loss of time deteriorates
Solution Approach 1:
By segmenting the light source into a reusable holder and a replaceable light-emitting member, the repair process is streamlined to only require replacement of the damaged light-emitting member. This eliminates the time-consuming process of replacing the entire light source assembly, including functional components like the heat dissipation component and electrical contacts, thereby reducing repair time while maintaining system reliability.
4Ease of repair
If the light-emitting member is detachably fixed to the light source holder, then ease of repair is improved, but device complexity deteriorates
Solution Approach 1:
The light source module is segmented into two main components connected through a standardized interface: the light source holder with mounting structure and the light-emitting member with corresponding mounting features. This segmentation enables easy replacement of the light-emitting member while adding minimal complexity through the use of simple, standardized mechanical and electrical connection interfaces.
Solution Approach 2:
The mounting structure combines multiple functions into a unified interface: mechanical attachment (screw portions), electrical connection (circuit contacts), and actuation (push switch for power contact). This merging of functions into a single integrated interface simplifies the replacement process compared to having separate mechanisms for each function, thereby improving ease of repair without proportionally increasing device complexity.

AI summary
A holder-and-emitting-member-separable light source module, which is a recessed light, a track light or an LED bulb, including a light source holder and a light-emitting member. The light source holder includes a heat dissipation component, a power contact, a circuit contact and a push switch. The light-emitting member includes a plurality of LED chips, a light circuit board, a power management module and a corresponding circuit contact. The light-emitting member is detachably fixed to the light source holder. When the light-emitting member is fixed to the light source holder, the circuit contact is in contact with the corresponding circuit contact. Thus, when an electronic component such as an LED chip or a power module is damaged, only the light-emitting member of the light source module need to be replaced without replacing the light source holder.
