Lighting Assembly Reflector System Narrow Beam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting assemblies that produce narrow light beams rely on expensive lens elements, which increases costs and complexity.
Innovation Solution
A lighting assembly with a reflector system featuring two concave surfaces of different radii of curvature, configured to direct light without a separate lens element, utilizing a fin system to reduce lateral reflections and a protection element to manage light output, achieving a narrow beam with high light transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a lens element is used to produce a narrow light beam, then the light beam narrowness is achieved, but the manufacturing cost increases
Solution Approach 1:
The patent removes the lens element from the lighting assembly, extracting the expensive optical component while replacing its function with a reflector system that shapes the light beam through reflection geometry rather than refraction
Solution Approach 2:
The patent replaces the optical refraction mechanism of the lens with a mechanical reflection system using precisely angled reflector surfaces, substituting one physical principle for another to achieve the same functional outcome with different cost characteristics
2Shape
If a lens element is used to produce a narrow light beam, then the light beam narrowness is achieved, but the device complexity increases
Solution Approach 1:
The patent merges the light-shaping function into the reflector system itself, combining the illumination and beam-shaping functions into a single integrated component rather than requiring separate lens and reflector elements
Solution Approach 2:
The reflector system performs multiple functions simultaneously: it redirects light from the LED, shapes the beam to achieve narrowness, and defines the optical path, making a single component serve multiple purposes that previously required separate elements

AI summary
A lighting assembly comprising a housing (2), a lighting system and a reflector system. The housing (2) has a longitudinal direction, a lateral direction and a height direction which are perpendicular to each other. The lighting system is installed in the housing (2) and configured to produce light and emit the light out from the housing (2), the lighting system comprising a first light source (61). The reflector system is configured for reflecting the light produced by the lighting system out from the housing (2) and comprises a first reflector (41) including a first reflector surface (411) which is a concave surface with a first radius of curvature (r1). The first reflector (41) is also provided with a second reflector surface (412) which is a concave surface with a second radius of curvature (r2) which is larger than the first radius of curvature (r1), a centre of curvature (cc2) of the second reflector surface (412) being spaced from a centre of curvature (cc1) of the first reflector surface (411) . The lighting assembly is configured to be such that most of the light emitted by the lighting system out from the housing (2) passes via the reflector system.
