Adjustable Landscape Lamp Shade for Light Direction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pathway and landscape lights have fixed top covers, limiting the ability to adjust light patterns, and lack adjustable side shades to control light emissions, which restricts the flexibility in lighting distribution.
Innovation Solution
The introduction of vertically adjustable top covers and raiseable/lowerable side shades allows for the control of light patterns by enabling the light source to emit light in different directions, with the top cover moving between down and raised positions to alter the light distribution, and side shades opening or closing to adjust peripheral light emissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed top cover is used on pathway lights, then the structure is simple and manufacturing is easy, but the ability to adjust light patterns is limited
Solution Approach 1:
The top cover is transformed from a fixed structure to a movable one, allowing it to rotate between different positions (e.g., covering the light source completely, partially covering, or removing entirely) to dynamically adjust light distribution patterns from omnidirectional to directional
2Adaptability or versatility
If fixed top covers are used without side shades, then the device complexity is low, but the control over light emissions in different directions is insufficient
Solution Approach 1:
The light shielding function is divided into two independent segments: a top cover for controlling upward light emission and side shades for controlling lateral light emission. Each segment can be independently adjusted to achieve precise control over light distribution in different directions
3Adaptability or versatility
If adjustable top covers and side shades are added to pathway lights, then light pattern control flexibility is enhanced, but the ease of operation decreases
Solution Approach 1:
The top cover and side shades are integrated into a unified adjustment system where both components can be manipulated together to achieve coordinated light distribution control, combining multiple adjustment functions into a single operational framework
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution provides enhanced flexibility in light pattern control, allowing for directed light distribution that can be adjusted to suit various applications, improving the functionality and aesthetic appeal of pathway and landscape lighting.
Implementation Method 1
The upper moveable assembly can include an upper cylinder with translucent sides having an upper diameter, and a lower cylinder with translucent sides having a lower diameter being smaller than the upper diameter.

AI summary
The pathway/landscape lamps include an elongated fixture body having an upper end and a lower end; at least one light source mounted to the upper end of the fixture body; a ground engaging post provided at the lower end of the fixture body; and a telescoping shade with a reflective top cover provided over the light source and translucent sides at least partially surrounding the light source. The telescoping shade configured to move from a lowered position allowing light from the light source to be directed downward, to a raised position allowing for light to be emitted both sideways and downward from the light source. A second embodiment of the telescoping shade include at least one vertically adjustable side shade configured to selectively block light to be emitted in a sideway direction.
