Description

LED lamp module and lamp

Technical Field

The application relates to an assembly structure of a lens and a reflecting cup, in particular to an LED lamp module and a lamp.

Background

The traditional LED lighting module is generally composed of an LED light source, a reflecting cup and a lens. The light emitted by the LED is firstly subjected to primary light distribution and light mixing through the lens, and then is finally emitted after being reflected by the inner surface of the reflecting cup. The structure is widely applied to scenes such as spot lamps, down lamps, stage lamps and the like, and the optical performance and the aesthetic property of the structure directly influence the competitiveness of products.

Currently, opaque materials or metal coating processes are adopted for the reflective cup and the lens, and the appearance is single white or metal color. Under the non-working state of the lamp, the whole module lacks visual layering sense, and the requirements of high-end decorative lighting on stealth and artistic devices are difficult to meet. After the LED light is refracted and mixed by the lens, the angle of part of the light beam is changed, and when the LED light reaches the curved surface of the reflecting cup, the reflecting path is deviated from the original design, so that bright and dark stripes appear on the light emitting surface. Secondary reflection of the lens output light by the light cup can destroy the existing light mixing uniformity.
