Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED aquarium lights suffer from low total light output, large size, high cost, and inability to provide an attractive shimmering effect due to the use of widely-spaced, individually-packaged LEDs, which also result in uneven spectral distribution and heat issues.
Innovation Solution
A compact, high brightness LED aquarium light apparatus featuring a densely-packed array of multiple LED chips without individual packaging, where the chips are closely spaced and emit light in a direction transverse to a small area, combined with an optical lens and reflector to create a well-mixed, intense light source that mimics natural sunlight and promotes marine life growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If widely-spaced, individually-packaged LEDs are used, then heat dissipation is improved, but device size increases and manufacturing cost increases
Solution Approach 1:
Multiple LED chips are densely packed and integrated into a single compact array without individual packaging, merging what would traditionally be separate components into one unified structure. This reduces overall device size while the array design allows heat to dissipate across the entire surface area.
Solution Approach 2:
The LED chips are positioned in specific patterns within the array to optimize both heat dissipation pathways and light output characteristics. The local arrangement of chips creates efficient thermal zones while maintaining compact dimensions.
2Temperature
If widely-spaced, individually-packaged LEDs are used, then heat dissipation is improved, but manufacturing cost increases
Solution Approach 1:
By eliminating individual packaging for each LED chip and integrating them into a single array structure, the manufacturing process is simplified. This merging of components reduces assembly steps, material usage for packaging, and overall manufacturing cost while maintaining effective heat dissipation.
Solution Approach 2:
The individual packaging step is extracted and removed from the manufacturing process. The LEDs are mounted directly onto the array substrate without separate packaging, reducing manufacturing complexity and cost.
3Temperature
If widely-spaced LEDs are used, then heat dissipation is improved, but spectral distribution uniformity deteriorates
Solution Approach 1:
LED chips with different wavelengths are strategically positioned in specific locations within the array to create uniform spectral distribution across the entire light output. The local arrangement of different wavelength chips ensures that all regions of the aquarium receive balanced spectral content.
Solution Approach 2:
The array is segmented into multiple wavelength zones that are carefully distributed throughout the structure. This segmentation allows different spectral components to be evenly dispersed, creating uniform spectral distribution when viewed from the aquarium side.
4Illumination intensity
If densely-packed LED chips are used, then light intensity increases and device size decreases, but heat dissipation becomes more difficult
Solution Approach 1:
Multiple LED chips are merged into a densely-packed array where the combined surface area of all chips provides adequate heat dissipation capability. The heat from numerous closely-spaced chips dissipates collectively across the entire array surface, maintaining effective thermal management despite high density.
Solution Approach 2:
Heat dissipation is addressed by utilizing the two-dimensional surface area of the array rather than relying solely on vertical spacing. The dense packing in the horizontal plane is compensated by effective thermal pathways across the array surface, allowing high light intensity while managing heat through surface-area-based dissipation.
5Illumination intensity
If densely-packed LED chips are used, then light intensity increases and device size decreases, but device complexity increases
Solution Approach 1:
The densely-packed LED chips are integrated into a single array structure that functions as one unified light source. This merging approach simplifies the overall device architecture compared to managing multiple separate LED assemblies, reducing structural complexity despite the high number of individual chips.
Solution Approach 2:
The array structure serves multiple functions simultaneously: it provides high light intensity through dense packing, maintains compact dimensions, and enables uniform spectral distribution through strategic chip arrangement. This multi-functionality reduces the need for additional separate components, thereby reducing overall device complexity.

AI summary
A compact high-brightness LED aquarium light fixture is described for use in illuminating aquarium tanks artificial light. (18) The LED aquarium light uses a densely-packed array of high-brightness light emitting diodes (LEDs) that are not individually packaged, where the array behaves similarly to a point source of light. The LED chips are distributed laterally over an area, where the LED chips have light emitting surfaces for emitting light in directions transverse to said area, wherein the dimensions of the area do not exceed 25 mm. Adjacent chips of the array are preferably separated by less than about 0.2 mm. The extended point source LED array, with its lens and associated reflector, result in a concentrated light source that attractively illuminates the contents of the aquarium, and creates a desirable shimmering effect within the aquarium. A clamp-on, flexible gooseneck mounting arrangement allows for use with aquarium tanks of various sizes.
