Description

A kind of LED downlight

technical field

The utility model relates to an LED downlight.

Background technique

Downlight is a kind of downlight embedded in the ceiling, which is generally used in hotels, homes, and coffee shops. Its biggest feature is that it can maintain the overall unity and perfection of architectural decoration, and will not destroy the perfect unity of ceiling art because of the setting of lamps. This kind of hidden lamp embedded in the ceiling projects all the light downwards, which belongs to direct light distribution.
