LED Lamp with Rotatable Light Sources for Adjustable Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elongated lamp products lack adjustable illumination angles, making it difficult to meet varying illumination requirements, especially with the increasing emphasis on energy conservation and carbon neutrality.
Innovation Solution
An LED lamp design featuring two movable light sources that can be rotated about the X, Y, and Z axes, allowing for adjustable illumination angles, comprising a lamp head assembly with rotatable parts and a pushable piece mechanism to secure the light sources in place, along with an infrared sensing module for control modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional elongated lamp structure is used, then manufacturing is simple, but illumination angle cannot be adjusted
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed lamp structure into a movable one. The light source assembly is made rotatable relative to the lamp body through a rotating shaft mechanism, allowing the illumination angle to be dynamically adjusted. The pushable piece provides selective positioning (fixed or movable state), enabling the system to switch between static and dynamic configurations as needed.
2Adaptability or versatility
If fixed illumination angle is used, then device complexity is low, but illumination requirements cannot be met
Solution Approach 1:
The pushable piece enables self-service operation by allowing users to directly manipulate and secure the light source assembly at desired positions without requiring tools or complex mechanisms. The user can freely adjust the illumination angle by pushing or releasing the piece, making the adjustment process simple and intuitive.
3Area of stationary object
If light source is fixed in position, then structural stability is high, but illumination area coverage is limited
Solution Approach 1:
The patent resolves this contradiction by making the light source position adjustable rather than fixed. The rotating shaft mechanism allows the light source assembly to be positioned at different angles to cover various illumination areas, while the pushable piece provides stability when a specific position is selected, combining both mobility and positional stability.

AI summary
An LED lamp with an adjustable space illumination angle comprises two movable light sources and a lamp head assembly. The two movable light sources are disposed on two sides of the lamp head assembly and spaced apart from each other in a length direction of the lamp head assembly. The two movable light sources are rotatably connected to the lamp head assembly. The two movable light sources are configured to be rotated about an X-axis or a Y-axis to change an included angle between the two movable light sources. The lamp head assembly comprises a first part connected with the two movable light sources and a second part connected with a lamp holder, and the first part is rotatably connected to the second part so as to enable the two movable light sources and the first part to rotate relative to the second part about a Z-axis.
