Solution Overview
Problem
Conventional solar ground lamps have inefficient solar energy absorption due to fixed solar panels, leading to short lighting times and safety hazards from exposed ground nails when not in use.
Innovation Solution
An outdoor lighting lamp design featuring a rotatable lighting module with an inclined solar panel and a storage mechanism for the ground nail, allowing adjustable solar panel positioning and secure nail storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the solar panel is arranged horizontally at the top of the ground lamp, then the structure is simple and easy to manufacture, but the light receiving position cannot be adjusted and the absorption efficiency of solar energy is poor
Solution Approach 1:
The solar panel is made rotatable relative to the ground lamp body through a rotation mechanism, allowing it to dynamically adjust its orientation to track the sun's movement throughout the day. This dynamic adjustment capability enables the solar panel to maintain optimal light reception angles, significantly improving solar energy absorption efficiency while preserving the basic structural simplicity of the ground lamp.
2Ease of operation
If the ground nail is exposed to the outside for easy installation, then the installation is quick and convenient, but it causes accidental injury to people when the ground lamp is not in use
Solution Approach 1:
The ground nail is stored within a storage cavity formed in the ground lamp body, creating a nested structure where the nail is kept inside the lamp housing when not in use. This nesting approach eliminates the safety hazard of exposed ground nails while maintaining quick installation capability, as the nail can be easily accessed and inserted through the assembly opening when needed.
3Stability of the object's composition
If the solar panel is fixed in position, then the device structure is stable and simple, but the lighting time at night is short due to insufficient electric power
Solution Approach 1:
The rotatable solar panel enables dynamic tracking of sunlight throughout the day, maximizing the amount of solar energy absorbed and converted to electrical energy. This increased energy absorption extends the charging duration and capacity, thereby extending the nighttime lighting duration while maintaining structural stability through the defined rotation axis and limiting pieces.

AI summary
The present invention provides an outdoor lighting lamp comprising a ground inserted base including an assembly opening and a ground nail, and a lighting module including a first shell, a light projection gap, a light emitting component, and a solar panel connected with the light emitting component. The light generated by electrifying the light emitting component is only projected by the light projection gap. One end of the first shell is mounted at the assembly opening, and the first shell is forced to rotate relative to the ground inserted base based on an axis of the ground nail to be a rotation axis. The solar panel is arranged at one end of the first shell where is in an opposite direction of the ground inserted base and not in horizontal. The solar panel adjusts a light receiving position by rotating the first shell relative to the ground inserted base.
