Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamps have a fixed illumination range, requiring multiple lamps and increased equipment, construction, and electric costs to achieve broader coverage, especially in applications like large building outlining, interior design, medical, cultural, and entertainment spaces.
Innovation Solution
A lamp design featuring a lighting and cooling module with fins, a reflective cup with a polyhedron inner wall for light refraction, and a diffuser plate with oblique circular arc and vertical riser elements to diffuse and refract light, expanding the illumination range through multiple refraction and diffusion stages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a conventional lamp projects light in a fixed angle, then the lamp structure is simple, but the illumination range is limited and multiple lamps are required
Solution Approach 1:
The lampshade is divided into multiple segments: a reflective cup with polyhedral inner wall for light refraction, a diffuser plate with oblique circular arc and vertical riser portions, and a wash wall cup with front and rear arc walls. Each segment performs a specific function in the light manipulation sequence, collectively expanding the illumination range from a fixed angle to a broad area suitable for wall washing effects.
2Area of stationary object
If multiple lamps are added to expand illumination range, then the coverage area increases, but equipment costs, construction costs, and electric bills increase significantly
Solution Approach 1:
The lamp is designed to perform multiple functions within a single device: the lighting element provides illumination, the reflective cup refracts light in multiple directions, the diffuser plate further disperses light, and the wash wall cup shapes the light distribution. This multi-functional design allows one lamp to replace multiple conventional lamps, achieving broad illumination coverage without increasing the quantity of lamps needed.
3Illumination intensity
If the lampshade wraps the lighting element and projects light in a predetermined direction, then the lamp structure is simple, but the light cannot be sufficiently refracted and diffused to provide a thorough wall washing effect
Solution Approach 1:
The lampshade incorporates curved surfaces including an oblique circular arc portion and a vertical riser portion in the diffuser plate, as well as front and rear arc walls in the wash wall cup. These curved geometries are specifically designed to refract and diffuse light effectively, creating a thorough wall washing effect that cannot be achieved with simple planar lampshade structures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a thorough wall washing effect with a single lamp, significantly reducing the need for multiple lamps and associated costs while providing a broader illumination area.
Implementation Method 1
the inner wall of the reflective cup being designed as a polyhedron for completely refracting the light diffused by the lighting element
Implementation Method 2
a diffuser plate, being a translucent plate, and further divided into an oblique circular arc plate and a vertical riser

AI summary
A lamp capable of expanding illumination range includes a lighting and cooling module, a reflective cup, a lampshade, a diffuser plate and a wash wall cup. The reflective cup and lampshade are connected to the lighting and cooling module; the lampshade surrounds the reflective cup; the diffuser plate is divided into an oblique circular arc plate and a riser; the circular arc plate has rule gratings formed by convex and concave embossed marks. A front arc wall is built on a side of the wash wall cup, and a rear arc wall is built on the other side. An inlay seam is formed between the front and rear arc walls; the circular arc plate is mounted onto the front arc wall; edges of the riser are plugged into the inlay seam; and the wash wall cup is plugged from the bottom of the lampshade to form the lamp.
