Snap-Positioned Lens Plate for Adjustable Parking Lot Light Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking lot lamps support only single power and single color temperature, lacking flexibility in light pattern adjustment, leading to high inventory costs and maintenance challenges.
Innovation Solution
A parking lot lamp design featuring a detachable lens plate with snaps for multiple light patterns (T2, T3, T4, T5) and adjustable power/color temperature, allowing easy switching and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single lens is used for each light pattern, then the structure is simple and low-cost, but the inventory backlog increases and maintenance costs rise
Solution Approach 1:
The lens plate is divided into multiple independent lens units that can be selectively positioned. Each lens corresponds to a specific light pattern (T2, T3, T4, or T5), and the lenses are arranged in a 2x2 grid on the lens plate. By segmenting the lens functions across multiple positionable units rather than requiring separate complete lens plates for each pattern, the system achieves light pattern flexibility while maintaining structural simplicity and reducing inventory requirements.
2Stability of the object's composition
If the lens plate is fixed to the lamp board assembly, then the structure is stable, but the light pattern cannot be adjusted
Solution Approach 1:
The lens plate is designed with movable lens units that can be dynamically repositioned between different snapping positions on the lamp board assembly. The lenses are mounted on a lens plate that can slide or shift to align different lenses with the LED light sources below. This dynamic positioning mechanism allows the system to switch between fixed stability (when positioned) and adjustable flexibility (when repositioning), enabling light pattern changes without compromising structural integrity.
Solution Approach 2:
A positioning mechanism serves as an intermediary between the lens plate and the lamp board assembly. This intermediary system includes guide rails, positioning holes, or snapping features that enable the lens plate to be easily moved and securely fixed at different positions. The intermediary mechanism decouples the stability function (provided by the snapping fixation) from the adjustability function (provided by the movable positioning system), allowing both requirements to be satisfied simultaneously.
3Adaptability or versatility
If multiple lens plates are provided for different light patterns, then all light patterns can be achieved, but the inventory cost and complexity increase
Solution Approach 1:
A single lens plate design serves multiple functions by incorporating all necessary lens types (T2, T3, T4, T5) in a 2x2 grid arrangement. The universal lens plate can be positioned in four different configurations, each configuration activating a specific light pattern. This multi-functional design eliminates the need for separate specialized lens plates for each light pattern, significantly reducing inventory complexity while maintaining full light pattern coverage capability.

AI summary
A parking lot lamp supporting multiple light patterns includes a lamp body, a lamp board assembly provided in the lamp body, and a lens plate snapped onto the lamp board assembly. A detachable cover plate is further provided on the lamp body for enclosing the lens plate in the lamp body. A plurality of LED light sources is provided on the lamp board assembly, and the lens plate is provided with lenses one-to-one corresponding to the LED light sources. The lenses are configured to form at least two LED light patterns when the lenses are aligned with and misaligned with the LED light sources. The lamp board assembly and the lens plate are provided with corresponding snaps. By means of the snaps, the lens plate and the lamp board assembly form at least two types of snapping positions, and the snapping positions correspond to the LED light patterns.
