Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional LED lighting configurations suffer from glare issues and inefficient heat dissipation, limiting their effectiveness and making high-powered LEDs impractical due to inadequate shielding and light distribution.
Innovation Solution
The design incorporates a shade module with specifically positioned shades and a lens module to direct light outward, using a cup-shaped structure with heat sinks and a rotating ring to manage glare and enhance light distribution, while the shade module's axial height is calculated to obstruct stray light effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If LED light source is located at the center of a reflector with light emission directed outward, then the lighting coverage is improved, but glare increases and beam angle becomes too wide
Solution Approach 1:
The patent divides the lighting system into multiple LED modules arranged in a specific geometric configuration rather than using a single central LED. This segmentation allows each module to contribute to overall coverage while individual modules can be positioned to avoid direct line-of-sight glare paths.
Solution Approach 2:
The patent transitions from a two-dimensional planar reflector configuration to a three-dimensional spatial arrangement of multiple LED modules at different heights and positions. This dimensional change enables better control over light distribution patterns and glare reduction by utilizing vertical space.
2Power
If multiple LEDs are used with light emissions directed outward from reflectors, then lighting intensity is improved, but heat dissipation efficiency deteriorates
Solution Approach 1:
The patent segments the high-powered LED system into multiple lower-powered modules distributed in space, which improves heat dissipation by increasing surface area and reducing thermal concentration, while maintaining overall lighting intensity through combined output.
Solution Approach 2:
The patent utilizes three-dimensional spatial distribution of LED modules to improve heat dissipation by allowing heat to dissipate in multiple directions rather than being confined to a single plane, thereby maintaining lighting intensity without excessive heat accumulation.
3Object-affected harmful factors
If traditional halogen apparatus uses a metal shield in the line sight, then glare prevention is attempted, but light dispersion efficiency deteriorates
Solution Approach 1:
The patent uses specially designed reflectors and optical elements as intermediaries to redirect and distribute light from multiple LED modules, achieving glare prevention through controlled reflection paths rather than direct blocking, thereby maintaining light dispersion efficiency.

AI summary
A LED lamp includes a number of lenses each of which includes a light emitting surface and a plurality of shades mounted on the light emitting surface. Each of the shades includes a hole whose sectional area in radial direction is equal to that of the light emitting surface. An axial height of the hole follows the formulaHφ=ϕmaxtanθmax,wherein Hφ is the axial height of the hole, φmax is a diameter value of the light emitting surface, and θmax is an output angle of the lens. Accordingly, a work area of the anti-glare LED lamp can be extend the most thereof since the shades block the stray light of a glare area of the LED lamp and strictly separates the work area from the glare area, and no stray light shot into eye in any areas. Therefore, the anti-glare LED lamp can achieve light distribution as designed without glare under cooperation of the lenses and the shades.
