Glare-Reduced Lamp With Segmented Light Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glare-reduced illumination technologies are limited in their ability to selectively illuminate different spatial areas independently of the lamp's orientation, leading to high glare when only one light segment is activated and restricting illumination to aligned areas.
Innovation Solution
A system comprising multiple switchable light sources assigned to specific spatial areas, activated by sensors detecting objects within those areas, which increases the active emission surface and reduces glare by using a control unit to adjust light intensity and position, with optical elements like reflectors or lenses to focus light on specific areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only one light segment is activated to illuminate a specific spatial area, then the illumination is selective and energy-efficient, but the effective emission surface is limited causing relatively high glare
Solution Approach 1:
The luminaire is divided into multiple independently controllable light segments, each with its own light sources and optical elements. This segmentation allows selective activation of specific segments while maintaining the option to activate multiple segments simultaneously to increase emission surface area and reduce glare when needed.
Solution Approach 2:
Multiple light sources within each light segment are optically combined through common optical elements (reflectors or lenses) to create a unified emission surface. This merging of multiple light sources increases the effective emission surface area while maintaining selective illumination capability, thereby reducing glare.
2Ease of operation
If light segments are permanently assigned to specific spatial areas, then spatial area illumination is simplified, but only those areas to which light segments are aligned can be illuminated
Solution Approach 1:
The system employs dynamic control of light sources within each light segment, allowing the illumination pattern to adapt in real-time based on detected object positions. The light sources can be independently adjusted to redirect light toward different spatial areas, enabling the same physical light segment to serve multiple areas dynamically.
Solution Approach 2:
Each light segment is designed with multiple light sources and optical elements that can be controlled to illuminate different spatial areas. This multi-functionality allows a single light segment to serve multiple purposes and illuminate various areas depending on the detected object position, eliminating the need for permanent alignment constraints.
3Device complexity
If the lamp orientation is fixed, then the structure is simplified, but illumination cannot adapt to different object positions independently of lamp orientation
Solution Approach 1:
The lamp structure is segmented into multiple independent light sources within each light segment, each capable of independent control. This segmentation allows the illumination pattern to be adjusted independently of the overall lamp orientation, as each light source can be directed toward its assigned spatial area without requiring physical reorientation of the entire lamp.
Solution Approach 2:
Each light source within a light segment has its own optical elements (reflectors or lenses) tailored to direct light toward specific spatial areas. This local optimization of light direction allows each light source to independently adapt to its assigned area's requirements, making the overall system adaptable to different object positions while maintaining a fixed, simple lamp structure.

AI summary
A method for glare-reduced illumination of a spatial area (1a, 1b) with a common emitting surface (2) consisting of grid-like adjacent luminaire segments (3) is described, wherein each luminaire segment (3) comprises a light source (4) and an optical element (6) downstream of the light source (4). To design a method of the type described above such that, selectively, different objects in active spatial areas are illuminated with reduced glare and largely independently of the orientation of a luminaire, it is proposed that the light source (4) comprises several light sources (7), which can be selectively switched and are each assigned to a spatial area (1a, 1b). A sensor (8) arranged in the area of the luminaire segments (3) detects an object (9) located in an active spatial area and activates the light sources (7) of the light source (4) assigned to the active spatial area to illuminate the object (9).
