Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED lamps with point light sources suffer from glare, reflection glare, and uneven illumination due to poor light distribution, leading to a messy and dim line light source effect, which increases production costs and energy attenuation.
Innovation Solution
A strip light fixture with a lamp holder, circuit board, point light sources, and a strip-shaped convex lens array that converts point light sources into sub-point light sources, enhancing light distribution and uniformity by using a combination of focusing and diffusing lenses to create a coherent line light source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a diffusion lamp cover is added to replace point light source with line light source, then glare and reflection glare are reduced, but the linear light source imaging becomes messy and fuzzy with poor light distribution
Solution Approach 1:
The diffusion lamp cover is segmented into multiple diffusion units arranged along the length direction, with each unit corresponding to a point light source. This segmentation allows precise control of light distribution for each segment, transforming the messy fuzzy line light source into a clear defined linear light source while maintaining glare reduction benefits.
Solution Approach 2:
A lens array is introduced as an intermediary component between the point light sources and the diffusion lamp cover. The lens array focuses and directs the light from point light sources onto specific regions of the diffusion cover, enabling precise control over light distribution and eliminating the messy imaging problem while maintaining glare reduction.
2Manufacturing precision
If more LED lamps are used to achieve line source effect, then line light source imaging is improved, but production cost increases
Solution Approach 1:
Multiple point light sources are merged with a single lens array and diffusion lamp cover assembly to create a unified line light source. This combining approach allows the system to function as a single integrated unit rather than requiring separate LED lamps for each position, thereby improving line light source imaging quality while reducing production costs.
Solution Approach 2:
The lens array serves multiple functions simultaneously: it focuses light from multiple point light sources, directs light onto the diffusion cover, and creates the linear light source pattern. This multi-functionality eliminates the need for additional separate components, reducing production costs while achieving high-quality line light source imaging.
3Device complexity
If point light sources are used directly for illumination, then structure is simple, but light distribution is poor with high energy attenuation
Solution Approach 1:
A lens array is introduced as an intermediary component that captures light from point light sources and redirects it to achieve better light distribution. The lens array acts as a mediator that transforms the poor light distribution of direct point light sources into an improved distribution pattern, reducing energy attenuation while adding minimal structural complexity.
Solution Approach 2:
The optical parameters of the system are changed by introducing the lens array, which modifies light direction, concentration, and distribution characteristics. This parameter change enables the system to achieve better light distribution and reduce energy attenuation while maintaining relative structural simplicity through the use of a compact lens array design.
