Description

Technical Field

[0001] This utility model belongs to the field of LED lighting fixture technology, and more specifically, it relates to a solderless, quick-assembly lamp cup. Background Technology

[0002] With the rapid development of LED lighting technology, the performance and assembly efficiency of the lamp cup, as a core optical component, directly affect the market competitiveness of the product. Traditional LED lamp cups generally use welding processes for electrical connection and structural fixation, such as connecting the light source circuit board to conductive terminals with solder and relying on welding to fix heat dissipation components. However, this process has significant drawbacks: First, the welding process requires precise temperature control and operation, which is time-consuming, resulting in low assembly efficiency and difficulty in meeting the needs of large-scale production; second, high-temperature welding can easily cause thermal damage to LED chips or circuit boards, reducing component reliability and lifespan; third, welding residues may cause short circuit risks, affecting product safety.

[0003] Furthermore, in terms of optical performance, conventional lamp reflector anti-glare designs often rely on a single structure (such as a frosted surface or simple texture), resulting in low light efficiency and incomplete glare elimination. Especially in narrow beam angle applications, concentrated light sources can easily create glaring spots, and traditional diffuse reflection coatings, due to process limitations, struggle to achieve uniform light scattering, impacting the user experience.

[0004] To address the aforementioned pain points, the industry urgently needs a lamp cup structure that balances efficient assembly, reliable connection, and excellent anti-glare performance. Therefore, this invention provides a solderless, quick-assembly lamp cup. Utility Model Content
