Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If direct downward light emission is adopted, then assembly is simplified, but glare problems occur
Solution Approach 1:
A reflective plate is introduced as an intermediary component between the light source and the downward direction. The light source emits light upward, which then reflects off the reflective plate to achieve downward illumination. This mediator resolves the contradiction by separating the light source position from the light emission direction, eliminating glare while maintaining assembly simplicity.
2Object-affected harmful factors
If diffuse reflection is adopted to solve glare, then glare is eliminated, but light source assembly becomes difficult
Solution Approach 1:
The reflective plate serves as a mediator that enables diffuse reflection to eliminate glare while keeping the light source assembly simple. The light source can be positioned independently without complex integration, as the reflective plate handles the light redistribution function.
Solution Approach 2:
The lamp structure is segmented into distinct functional components: the light source assembly and the reflective plate assembly. This segmentation allows the light source to be assembled independently and simply, while the reflective plate separately provides the diffuse reflection function to eliminate glare.
3Ease of manufacture
If light source is positioned for direct downward emission, then assembly is easy, but heat dissipation is compromised
Solution Approach 1:
Instead of positioning the light source to emit light directly downward, the light source is inverted to emit light upward. The reflective plate then redirects this upward light to achieve the desired downward illumination. This inversion resolves the contradiction by decoupling the light source position from the effective light emission direction, enabling both easy assembly and proper heat dissipation.

Function Achieved in This Case
Facilitates assembly of the light source and heat dissipation components, improves heat dissipation, and ensures uniform light emission without glare, enhancing the overall performance of the lamp.
Implementation Method 1
the problem of glare may be caused by adopting direct downward light emission. In order to solve the problem of glare, light is generally emitted through diffuse reflection

AI summary
A light-emitting lamp structure with diffuse reflection includes: a reflector cup having a run-through mounting hole; a heat dissipation assembly, at least a part of the heat dissipation assembly being provided inside the reflector cup through the mounting hole; and a light source assembly provided inside the reflector cup along a side wall of the heat dissipation assembly. By providing the mounting hole in the reflector cup, a part of the heat dissipation assembly is provided inside the reflector cup through the mounting hole, so that the light source assembly is provided along the side wall of the heat dissipation assembly, thereby facilitating assembly between the light source assembly and the heat dissipation assembly while avoiding glare caused by direct downward light emission from the light source assembly.
