Rotating lamp, refrigerator, and control method for rotating lamp in refrigerator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerator lamps are fixed at the top, causing direct visual stimulation and inadequate lighting in the drawer area due to obstruction by shelves and items, making it difficult for users to find items.
Innovation Solution
A rotating lamp system with a driving device, transmission mechanism, and lamp box assembly that adjusts its light exiting surface position based on the door and drawer states, ensuring optimal lighting direction within the refrigerator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lamp is fixed at the top of the refrigerator, then the structure is simple, but the light directly stimulates the user's eyes and creates inadequate lighting in the drawer area
Solution Approach 1:
The lamp box assembly is made rotatable relative to the box, allowing the light exiting surface to dynamically adjust its orientation. When the door is opened, the driving device rotates the lamp box assembly to direct light inward rather than toward the user's eyes, eliminating visual stimulation while maintaining simple structural design
Solution Approach 2:
The system detects door opening in advance and pre-rotates the lamp box assembly to the appropriate position before the user fully opens the door. This preliminary adjustment ensures that light is already directed inward when the door is opened, preventing visual stimulation from the outset
2Illumination intensity
If the lamp is fixed at the top, then the device complexity is low, but the lighting in the drawer area is insufficient due to obstruction by shelves and items
Solution Approach 1:
The lamp box assembly can rotate to different positions to illuminate various areas. When the drawer is opened, the system rotates the lamp box assembly to direct light into the drawer area, overcoming obstructions from shelves and items. This dynamic adjustment provides intensive lighting where needed without requiring multiple fixed lamps or complex multi-position mechanisms
Solution Approach 2:
A single lamp box assembly serves multiple functions by rotating to different positions: illuminating the main compartment when the door is opened and illuminating the drawer area when the drawer is opened. This multi-functionality achieves adequate lighting in both areas without increasing device complexity

AI summary
The present disclosure provides a rotating lamp, a refrigerator, and a control method for a rotating lamp in a refrigerator. The rotating lamp is disposed in a box having a door and a drawer, the rotating lamp includes a driving device, a transmission mechanism and a lamp box assembly, and the driving device includes an output shaft; the lamp box assembly is rotatably arranged in the box and has a light exit surface; one end of the transmission mechanism is connected to the output shaft, and the other end is connected to the lamp box assembly. When the door is opened or when the drawer (30) is drawn out, the driving device drives the lamp box assembly via the transmission mechanism to rotate the lamp box assembly relative to the box.
