Solution Overview
Problem
Existing lamps and lanterns face limitations in heat dissipation efficiency, leading to inadequate performance when attempting to provide multi-directional lighting, as excessive light sources generate higher heat dissipation requirements that current systems struggle to manage effectively.
Innovation Solution
A multi-angle lighting lamp design featuring a lamp holder, multiple lamp boards, protective covers, and a heat dissipation part that forms a convection channel within the lamp cavity, allowing air flow to effectively remove heat through strategically positioned heat sinks and vents, enhancing cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light sources are used to achieve multi-directional lighting, then the lighting coverage is improved, but the heat dissipation requirements increase and heat dissipation efficiency deteriorates
Solution Approach 1:
The lamp is divided into multiple independent lamp boards, each with its own light sources and heat dissipation structures. This segmentation allows heat to be distributed across multiple localized dissipation points rather than concentrating thermal energy in a single area, improving overall heat dissipation efficiency while maintaining multi-directional lighting coverage.
Solution Approach 2:
Heat dissipation fins are introduced as intermediary structures between the light sources and the surrounding environment. These fins act as thermal intermediaries that facilitate heat transfer from the lamp beads to the air, enhancing heat dissipation efficiency without requiring additional active cooling components.
2Loss of energy
If heat dissipation structures are added to improve cooling, then heat dissipation efficiency is improved, but the structural complexity increases
Solution Approach 1:
The heat dissipation fins are merged with the lamp board structure itself, forming an integrated assembly. This combination eliminates the need for separate heat dissipation components and simplifies the overall structure, achieving improved heat dissipation efficiency without significantly increasing structural complexity.
Solution Approach 2:
The lamp board serves multiple functions: it provides structural support for the light sources, acts as a mounting platform for electrical components, and functions as a heat dissipation structure through its integrated fins. This multi-functionality reduces the need for additional dedicated heat dissipation structures, maintaining structural simplicity.

AI summary
The utility model discloses a multi-angle lighting lamp, which comprises: a lamp holder, a plurality of lamp boards and a plurality of protective covers; a plurality of protective covers are connected to the lamp board one by one, and the protective covers are covered on the lamp beads; there is a heat sink between two adjacent protective covers, and the heat sinks are communicated with the lamp cavity, so that the convection channel can be formed inside the lamp cavity, so that the air flow can directly and effectively blow the heat dissipation part, and then the air flow can better take away the heat of the dissipation part, thus, the heat on the lamp board is effectively discharged through the heat dissipation part, so the overall heat dissipation efficiency of the lamp has been greatly improved.
