Auto-Adjustable Lens Light Fixture for Inclination Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wash lights with multiple focus lenses face operational issues when the mounting plate becomes inclined due to power failures or external forces, leading to compromised focusing and condensing effects, as existing systems lack automatic adjustment mechanisms to maintain perpendicularity.
Innovation Solution
A light fixture system with an auto-adjustable lens that utilizes a supporting arm, light head, and independent driving mechanisms, along with angle detectors and controllers, to automatically adjust the lens to a perpendicular position relative to the light source, ensuring proper alignment and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single mounting plate with multiple focus lenses is used, then the focusing function is achieved, but the system becomes vulnerable to inclination when power fails or external force acts, causing operational failure
Solution Approach 1:
The patent divides the single mounting plate into multiple independent mounting plates, each carrying one or more focus lenses. Each mounting plate is independently driven by its own motor, allowing individual adjustment and compensation when the system experiences inclination or power failure, thereby improving reliability without excessive complexity.
Solution Approach 2:
The system dynamically adjusts the position parameters of individual mounting plates along the optical axis based on detected inclination angles. By changing the axial positions of specific mounting plates independently, the system compensates for inclination effects and maintains proper focusing functionality.
2Ease of operation
If three or four motors are used to drive the mounting plate, then the focus lens can move along the outgoing direction, but the system cannot compensate for inclination when the mounting plate becomes tilted
Solution Approach 1:
The system incorporates angle detectors that continuously monitor the inclination angle of the mounting plate. This feedback information is used by the control system to automatically adjust the positions of individual mounting plates via independent motors, enabling the system to compensate for inclination and maintain proper operation.
Solution Approach 2:
The system transitions from a static mounting plate configuration to a dynamic one where individual mounting plates can move independently along the optical axis. This dynamic adjustment capability allows the system to adapt to changing inclination conditions and maintain focusing performance.
3Manufacturing precision
If the mounting plate is kept perpendicular to the outgoing direction, then normal operation is maintained, but the system fails when the head rotates and the mounting plate becomes inclined
Solution Approach 1:
By segmenting the mounting plate into multiple independently controllable units, the system can maintain perpendicularity of each segment relative to the outgoing light direction even when the overall head rotates. Each segment can be independently positioned to compensate for rotational-induced inclination.
Solution Approach 2:
The system dynamically adjusts the axial positions of individual mounting plate segments in response to head rotation. This dynamic repositioning maintains the perpendicular relationship between each lens and the outgoing light direction, enabling the system to adapt to rotational movements while preserving optical alignment.
Data Source
AI summary
A light fixture system with auto-adjustable inclination angle of a lens includes a case, a supporting arm pivotally connected to the case and rotatable in a first dimension, and a light head pivotally connected to the supporting arm and rotatable in a second dimension. The light head is provided with a light source, a light-transmitting lens, and at least three driving mechanisms for driving the light-transmitting lens to move along an outgoing direction of the light source, and the driving mechanisms are independent from each other and not located in the same line. An angle detector is used to monitor an included angle of the light-transmitting lens with respect to the outgoing direction of the light source, when the light-transmitting lens is not perpendicular to the outgoing direction of the light source, the light-transmitting lens is controlled to be perpendicular to the outgoing direction of the light source.
