Angled Bracket Lamp Module for Downward Light Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional street lamps struggle to effectively direct light downward while preventing emission parallel to the ground or upward, especially with the transition from a pole, which can lead to inefficient lighting and glare issues.
Innovation Solution
A light fixture assembly with a housing and modular lamp units featuring angled brackets and optics that prevent light from being emitted parallel to the ground or upward, utilizing a stair-like pattern of brackets and a reflector to direct light downward, and an outer diffuser to manage light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional street lamps are mounted on poles, then elevated lighting position is achieved, but light emission occurs in unwanted directions (parallel to ground and upward) causing glare and inefficiency
Solution Approach 1:
The light fixture is divided into multiple lamp units, each with its own angled bracket and optical controls. This segmentation allows independent directionality control for each light source, enabling precise downward light emission while blocking unwanted directions.
Solution Approach 2:
Each lamp unit is equipped with specific optical components (reflectors, diffusers, and angled brackets) tailored to direct light downward. The housing and brackets are designed with specific angular geometries to control light distribution locally at each lamp unit, ensuring downward emission while preventing glare.
2Illumination intensity
If light fixtures use modular lamp units with angled brackets, then light directionality is improved, but device complexity increases
Solution Approach 1:
The modular lamp units are designed to be universal and interchangeable within the housing. Each lamp unit serves multiple functions: mounting via angled bracket, light emission, and glare prevention. This multi-functionality reduces the need for separate components and simplifies the overall system despite the modular structure.
Solution Approach 2:
The lamp units are nested within the housing structure, with each unit containing integrated components (bracket, reflector, diffuser) that work together. This nesting approach consolidates multiple functions into compact modular units, reducing overall system complexity while maintaining directionality control.

AI summary
A light fixture includes a housing defining a recessed cavity. The housing has a top, a first side, and a second side each extending at an angle from a first end of the housing to a second end of the housing, the first end being substantially orthogonal relative to a first plane. One or more lamp units are positioned in the housing to emit light therefrom, wherein the emitted light is prevented from leaving the housing in a direction parallel to the first plane.
