Removable Pool Light Cartridge for Wall-Mounted Fixture Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool lighting fixtures require the entire fixture to be removed for bulb replacement, which is cumbersome due to the need for long power cables and involves removing the housing from the pool wall, making maintenance and servicing inefficient.
Innovation Solution
A removable pool lighting assembly with a light cartridge that includes a light emitting diode, circuitry, and a heat sink, which can be exchanged without removing the light fixture body from the pool wall, along with interchangeable lenses providing different lighting patterns, and a method for installing, maintaining, and servicing the assembly without the need for excess power cord or removing the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the entire light fixture is removed from the pool wall for bulb replacement, then the light bulb can be accessed and replaced, but the maintenance process becomes cumbersome and time-consuming due to the need to remove the housing and handle long power cables
Solution Approach 1:
The lighting assembly is divided into separate functional modules: a fixed housing that remains installed in the pool wall, and a removable light cartridge containing the bulb and electrical components. This segmentation allows the light cartridge to be extracted and replaced independently without disturbing the housing or power cable connections, enabling quick bulb replacement while eliminating the need to handle the entire fixture and long power cables during maintenance.
2Ease of repair
If the entire light fixture is removed from the pool wall for servicing, then internal components can be accessed, but the process becomes complex and inefficient due to the need to disconnect power cables and reinstall the housing
Solution Approach 1:
The light cartridge is extracted as a complete serviceable unit from the housing. The cartridge contains the bulb, socket, and associated electrical components, all accessible through a single removal action. This extraction approach allows technicians to access and service internal components without the complexity of disconnecting power cables or manipulating the housing, reducing the service procedure to a simple insert-remove operation.
3Ease of operation
If long power cables are used to position the fixture away from the pool wall, then the fixture can be removed for bulb replacement, but the cable management becomes cumbersome and aesthetically unpleasing
Solution Approach 1:
The power cable connection is merged with the fixed housing rather than being attached to the removable light cartridge. The housing contains the electrical interface and power cable connections, which remain stationary and connected to the power source. The light cartridge connects to this interface during installation, eliminating the need for long external power cables and complex cable management during bulb replacement operations.

AI summary
Pool lighting assemblies, lens and methods of installing, maintaining and servicing are disclosed. A pool lighting assembly can include a light fixture body forming an elongated housing with a generally open interior, where the light fixture body constructed for insertion into a structure, such a pool wall. Additionally, a light cartridge can be provided. The light cartridge can have an illumination portion with a light emitting diode, a circuitry portion for controlling the light emitting diode, and a heat sink in proximity of the light emitting diode and the circuitry portion. A lens assembly, attachable to the light fixture body, can also be provided. The lens of the lens assembly can be interchangeable with a different lens. Also, the light cartridge can be removable from the light fixture body without removing the light fixture body from the structure.
