Electronically Adjustable Solid-State Luminaire Beam Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional adjustable lighting fixtures rely on mechanical components and require manual adjustment by technicians, which is costly, complex, and poses safety risks, especially in hard-to-reach areas, and existing digital systems need manual addressing of each LED, complicating control.
Innovation Solution
A solid-state luminaire with electronically adjustable light beam distribution controlled through a user interface on a computing device, allowing wireless or wired control of light distribution without needing to know the luminaire's specifics, such as the number of LEDs or their addresses, using controllers and communication protocols like DMX, Wi-Fi, or Bluetooth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mechanical components (lenses, track heads, gimbal mounts) are used to adjust light direction, then light distribution can be adjusted, but device complexity and cost increase
Solution Approach 1:
The patent replaces mechanical adjustment systems (lenses, track heads, gimbal mounts) with an electronically controllable LED array system. Each LED can be independently controlled to change light distribution patterns, eliminating the need for complex mechanical components while maintaining adaptability in light direction and distribution.
Solution Approach 2:
The lighting system is divided into multiple independently controllable LED units, each capable of being adjusted individually. This segmentation allows the system to achieve complex light distribution patterns through electronic control of individual segments rather than requiring complex mechanical adjustment of a single light source.
2Ease of operation
If manual adjustment by technicians is required, then light distribution can be controlled, but safety risks and operational difficulty increase
Solution Approach 1:
The system enables self-service operation through automated electronic control interfaces. Users can control light distribution patterns without requiring manual physical adjustment, eliminating safety risks associated with technicians working in hard-to-reach areas. The electronic system automatically manages the complex coordination of multiple LEDs to achieve desired light patterns.
3Measurement precision
If individual LED addressing is required for digital control, then precise control is achieved, but ease of operation decreases
Solution Approach 1:
The patent introduces an intermediary control system that manages the addressing and coordination of individual LEDs. This intermediary layer translates simple user commands into precise control signals for multiple LEDs, maintaining exact control over each LED while shielding the user from the complexity of individual addressing. The intermediary handles the complex task of coordinating LED addresses and control signals automatically.

AI summary
Techniques and user interfaces (UIs) are disclosed for controlling a solid-state luminaire having an electronically adjustable light beam distribution. The disclosed UI may be configured, in accordance with some embodiments, to provide a user with the ability to control, by wireless and/or wired connection, the light distribution of an associated solid-state luminaire in a given space. The UI may be hosted by any computing device, portable or otherwise, and may be used to control any given light distribution capability provided by a paired luminaire. In accordance with some embodiments, the user may provide such control without need to know details about the luminaire, such as the quantity of solid-state lamps, or their individual addresses, or the address of the fixture itself. In some cases, the disclosed techniques may involve acquiring spatial information of the space that hosts the luminaire and/or providing user-selected distribution of light within that space.
