Abstract: A lighting device includes a prism plate, an anti-glare cup, a housing, a light source board, a heat dissipation assembly, and a lenses plate. The prism plate includes a refraction optical component. For example, make many micro-lenses on a surface of a transparent plastic material or a transparent plastic plate by compression molding, cutting, and injection molding. The combination of these optical lenses adjusts the beam angle of light to fulfill users' needs. The surface material of the anti-glare cup features on preventing visual glare. The housing is used to fasten the prism plate and the anti-glare cup. The light source board is for installation of a LED module. Besides, the heat dissipation assembly carries the light source board. The heat dissipation assembly is connected to the housing.

Abstract: An assembly structure for an embedded light device includes a detachable installation module and an outer ring of the embedded light device. The detachable installation module has sliding grooves extending along with an installation direction and a lock piece having one end abutting against a position recovery element. When the position recovery element is in an initial position, a lock portion at the other end of the lock piece is exposed in the sliding grooves along with a direction perpendicular to a direction of the sliding grooves. When the position recovery element is compressed, the lock piece is compressed along the direction perpendicular to the sliding grooves. The outer ring includes a sliding track for slidably engaging with the sliding grooves. The sliding track includes an engaging piece, the engaging piece including a pressing surface and a locking surface.
