Recessed Refrigerator LED Lamp Layout for Uniform Cooling-Safe Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerator lamp apparatuses fail to provide uniform illumination throughout the storage space, especially the lower portions, and generate heat, increasing power consumption and temperature, which necessitates additional refrigeration cycles.
Innovation Solution
A lamp apparatus is designed with a light source unit comprising LEDs installed parallel to the rear wall, a recessed lamp receiving part, and a diffusing lamp cover, which ensures even illumination from top to bottom and reduces heat emission by using LEDs and a multi-duct cover with cold air discharge holes, along with a controller to manage light based on door openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional lamp apparatus is used, then illumination is provided, but heat is generated increasing temperature and power consumption
Solution Approach 1:
The light source is changed from conventional incandescent or fluorescent lamps to LEDs (Light Emitting Diodes). This parameter change in the light source technology fundamentally alters the energy conversion efficiency, with LEDs converting electrical energy directly to light with minimal heat generation, thereby maintaining illumination while preventing temperature increase and reducing power consumption.
2Illumination intensity
If the lamp emits direct light, then illumination is strong, but eye-dazzling occurs and aesthetic appeal is reduced
Solution Approach 1:
A translucent lamp cover is introduced as an intermediary between the LED light source and the storage space. This cover diffuses the direct light into scattered, soft illumination, eliminating eye-dazzling effects while maintaining adequate brightness. The diffused light also creates a more aesthetically pleasing environment within the refrigerator.

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 provides uniform illumination, reduces eye-dazzling direct light, minimizes heat and power consumption, and enhances aesthetic appeal while maintaining optimal storage conditions for food items.
Implementation Method 1
a lamp cover for diffusing light emitted from the light source unit
Implementation Method 2
a multi-duct cover having a plurality of discharge holes discharging cold air to the storage space

AI summary
A refrigerator having a lamp apparatus includes: a lamp receiving part formed at a recess portion of a rear wall surface of a storage space of the refrigerator; a light source unit installed at the lamp receiving part and being parallel to the rear wall surface of the storage space; and a lamp cover for diffusing light emitted from the light source unit. Because the light source unit and the lamp cover are provided at the lamp receiving part formed at a recess portion of the rear wall surface of the storage space of the refrigerator, both upper and lower ends of the storage space may be uniformly illuminated.
