LED Insert with Movable Lens Housing for PARCAN Zoom and Focus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED inserts for parabolic aluminized reflector lights (PARCANs) are limited in providing multiple color options and adjustable zoom and focus, as they often require gel filters, which are time-consuming and restrictive, and dedicated LED units that offer color options lack the ability to produce white light.
Innovation Solution
An LED insert with a light housing, support rods, a control circuit, motor, gear system, and threaded rod mechanism that allows for adjustable focus and zoom of LED lights, enabling users to control color and sequence through a remote or wired control panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If gel filter screens are attached to the front of PARCANs to add color, then the PARCAN can produce colored light, but the process is time-consuming and only allows for one additional color
Solution Approach 1:
The patent implements a dynamic color selection system using an LED insert with multiple color LEDs that can be electronically switched between different colors. This allows the PARCAN to change colors dynamically without physical gel filter replacement, resolving the contradiction between color versatility and time consumption.
Solution Approach 2:
The patent replaces the mechanical gel filter system with an electronic LED color control system. Instead of physically attaching and detaching gel filters, the system uses electronic control to switch between different colored LEDs, eliminating the time-consuming mechanical process while maintaining color versatility.
2Adaptability or versatility
If gel filter screens are used to add color to PARCANs, then colored light is produced, but the zoom and focus properties cannot be adjusted
Solution Approach 1:
The patent creates a multi-functional system where the LED insert serves multiple purposes: it provides color variation through different colored LEDs, and simultaneously enables zoom and focus adjustment through the movable lens housing. This universal component achieves both color control and optical adjustment functions.
Solution Approach 2:
The patent implements dynamic adjustability by allowing the lens housing to move along guide rods, enabling real-time changes in focus and zoom. This dynamic mechanical adjustment works in conjunction with the electronic color control, providing versatile operation that combines color changeability with optical flexibility.
3Adaptability or versatility
If dedicated LED units are used to produce different colors, then multiple colors are available, but the units cannot produce white light and are very expensive
Solution Approach 1:
The patent merges different colored LEDs into a single insert assembly that can be installed in existing PARCANs. By combining multiple color LEDs with a movable lens housing in one unit, the system achieves color versatility while maintaining compatibility with traditional PARCAN designs and avoiding the need for expensive dedicated LED units.
Solution Approach 2:
The LED insert is designed to be universal, working with existing PARCAN fixtures while providing multiple color options and white light capability. The insert serves as an adaptable component that maintains the original PARCAN structure while adding enhanced color production and optical adjustment functions.
4Adaptability or versatility
If a movable lens housing is added to enable zoom and focus adjustment, then optical flexibility is improved, but the device complexity increases
Solution Approach 1:
The patent introduces guide rods as intermediary elements that simplify the mechanical connection between the lens housing and the LED insert. These guide rods provide a straightforward mechanical pathway for movement, reducing the complexity of the overall assembly while enabling smooth zoom and focus adjustment through the movable lens housing.
