Rotatable Light Directing Members for Directional Lamp Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional lamps lack the ability to precisely control light direction, resulting in inefficient light distribution and limited flexibility in creating aesthetically pleasing or functionally effective lighting arrangements.
Innovation Solution
A lamp design featuring an elongate support with rotatable light directing members and light sources positioned along its length, allowing each light directing member to independently direct light in specific directions by rotating around the support, with each member having an interior passage to channel light away from the lamp in two opposite directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional lamps emit light in all directions, then the light distribution is simple and the structure is simple, but the light direction control is poor and light distribution efficiency is low
Solution Approach 1:
The lamp divides the light directing function into multiple independent light directing members (first, second, third light directing members) that can be individually rotated and positioned. Each light directing member independently controls the direction of light from specific light sources, enabling precise directional control without requiring complex centralized control mechanisms.
Solution Approach 2:
The light directing members are designed to be rotatable about the elongate support, transforming the static light distribution of traditional lamps into a dynamic system where users can adjust light directions in real-time. This rotational capability provides operational flexibility while maintaining a relatively simple structural framework.
2Productivity
If light directing members are added to control light direction, then light direction control improves, but the device complexity increases
Solution Approach 1:
Multiple light sources and light directing members are integrated along a single elongate support structure, merging the support function with the light distribution function. This consolidation reduces the need for separate mounting structures and simplifies the overall device architecture while maintaining efficient light distribution capability.
Solution Approach 2:
The elongate support serves multiple functions: it supports all light sources, supports all light directing members, provides an axis for rotation, and acts as a structural framework. This multi-functionality reduces the number of separate components needed, improving light distribution efficiency without proportionally increasing device complexity.
3Adaptability or versatility
If light sources are positioned along the elongate support with light directing members, then light can be directed to specific areas, but the manufacturing complexity increases
Solution Approach 1:
The lamp is designed as a modular system where light sources and light directing members are independent segments that can be separately manufactured and then assembled along the elongate support. This segmentation allows each component to be optimized and manufactured independently, reducing overall manufacturing complexity despite the system's versatility.
Solution Approach 2:
Different light directing members can be positioned at different locations along the elongate support and rotated to different angles, allowing each zone of the lamp to be optimized for specific lighting needs. This localized control provides high adaptability for different lighting scenarios while maintaining a standardized modular structure that simplifies manufacturing.

AI summary
A lamp (10, 30) comprises: an elongate support (14, 34), a plurality of light directing members (18, 38), and a light generating unit (16, 36). The light directing members (18, 38) are supported by the elongate support (14, 34) at respective different positions along the length of the elongate support (14, 34). Each light directing member (18, 38) is rotatable at least partially around the elongate support (14, 34) to select a rotational position of the light directing member (18, 38) from a respective range of rotational positions of the light directing member; Each light directing member (18, 38) cooperates with the light generating unit (16, 36) so that at any rotational position within said respective range of rotational positions of the light directing member, the light directing member receives light from the light generating unit and directs the light away from the lamp in a direction dependent on the selected rotational position of the light directing member.
