Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If fins are used for heat dissipation in existing mining lights, then heat dissipation function is provided, but the fins do not fit well with the shell resulting in low structural strength and poor heat dissipation effect
Solution Approach 1:
The heat dissipating fins are integrated with the heat dissipating plate to form an integral structure, merging the heat dissipation function with the structural support function. This integration ensures that the fins are firmly attached and cannot detach, simultaneously improving both structural strength and heat dissipation effectiveness.
Solution Approach 2:
The heat dissipating plate serves multiple functions: it provides structural support for mounting the light source and power supply, acts as a heat conduction path from heat-generating components, and supports the heat dissipating fins for convective heat transfer. This multi-functionality resolves the contradiction by making the structure both strong and thermally efficient.
2Temperature
If conventional heat dissipation structures are used, then simple design is maintained, but heat dissipation efficiency is poor
Solution Approach 1:
The invention introduces a three-dimensional annular passage structure surrounding the heat dissipating plate, creating a dedicated air flow channel in the vertical dimension. This dimensional addition enables efficient convective heat transfer without complicating the overall design, as the annular passage naturally guides air flow from bottom to top.
Solution Approach 2:
The annular passage structure enables natural convection current to form automatically, where heated air rises through the passage and cooler air is drawn in from the bottom, creating a self-sustaining heat dissipation system without requiring external fans or complex control mechanisms.

AI summary
The present disclosure discloses a lighting lamp including a casing, a heat dissipating plate, heat dissipating fins, a light source plate, a power supply and a light transmitting member. The heat dissipating plate is spaced from the casing to form an annular passage. The heat dissipating fins are spaced along a circumference of a back side of the heat dissipating plate. A portion of each heat dissipating fin is located within the annular passage. The light source plate and the light transmitting member are located on a front side of the heat dissipating plate in sequence. The power supply is located above the back side of the heat dissipating plate. Heat generated by the light source plate and the power supply is conducted to the annular passage and is then carried away by air flow in the annular passage.
