Solution Overview
Problem
Conventional LED light sources face limitations in adjusting light angles, leading to light pollution and energy waste due to fixed emission modes and compatibility issues with different lamp housings.
Innovation Solution
A multi-angle light source device with a holder, housing, and power supply, featuring a rotating body with a fixing portion, connecting portion, and illuminants, allowing for flexible adjustment of light angles and independent rotation of components to accommodate various lighting directions, reducing light pollution and energy waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a full-angle electronic light source is selected to emit light in multiple directions, then the light emitting modes cover downward, obliquely downward, left and right, front and rear, obliquely upward directions, but extra light is generated by non-illuminated angles resulting in light pollution and waste of electric energy
Solution Approach 1:
The patent implements a rotatable connecting portion that allows the illuminant to dynamically adjust its emission angle. The connecting portion can rotate relative to the fixing portion, enabling the light source to change its luminous angle from full-angle to multi-angle modes, thereby directing light only where needed and eliminating waste from non-illuminated angles
Solution Approach 2:
The patent changes the emission parameter by allowing rotation of the connecting portion to different angles. This enables the system to switch between different luminous angles (full-angle, multi-angle, directional) based on actual lighting needs, optimizing energy utilization by matching light emission patterns to specific application requirements
2Ease of operation
If a conventional LED lotus lamp with uniformly arranged light modules is used, then the emitting light direction can be adjusted by rotating light modules, but the number of light modules and adjustable angle range limit compatibility with different complex lamp housings
Solution Approach 1:
The patent creates a universal light source device that can adapt to different lamp housing types (downward, obliquely downward, left and right, front and rear, obliquely upward directions) through the rotatable connecting portion. This single device structure replaces the need for multiple fixed-angle light modules, achieving multi-functionality and broad compatibility across various lighting applications
3Device complexity
If the power supply is integrated with the illuminant, then the structure is compact, but the heat dissipation performance is reduced due to proximity of heat source and power supply
Solution Approach 1:
The patent extracts the power supply from the illuminant assembly and places it in a separate housing. This separation removes the heat source (illuminant) from proximity to the power supply, enabling independent heat dissipation pathways and improving thermal management performance while maintaining structural compactness through modular design

AI summary
A multi-angle light source device includes a holder, a housing movably connected with the holder and rotated relative to the holder, a power supply received in the housing and electrically connected to the holder, and a body fixedly connected to the housing. The body includes a fixing portion fixedly connected to the housing, a connecting portion rotated relative to the fixing portion and at least one illuminant formed on a distal portion of the connecting portion to rotate relative to the connecting portion. The present structure can flexibly adjust its luminous angle so that it can be conveniently used in different lamp-housings, suppress light pollution, reduce waste of electric energy, and further improve its heat dissipation performance of the product by the power supply separating from its heat source of each illuminant.
