Down light structure

Abstract

Disclosed is a down light structure. The down light structure comprises a lamp holder and a lamp body; the lamp holder comprises a top plate and a circular ring seat; four grooves are formed in the upper end of the circular ring seat, and springs are arranged in the corresponding grooves; the top plate is placed in the circular ring seat, four convex points are arranged on the top plate, and the convex points are embedded in the corresponding grooves and are connected with the corresponding springs; two binding posts are arranged above the top plate, and a contact and a contact ring are arranged below the top plate; an annular bottom edge is arranged at the lower end of the circular ring seat; four round holes are formed in the bottom edge, bolts are correspondingly arranged in the round holes, and movable strips are correspondingly arranged on the bolts; a fixed piece is arranged on the outer side of the circular ring seat and beside the round holes; the lamp body is provided with a shell, an LED panel and a connecting seat; the connecting seat is cylindrical, two contacts are arranged at the top of the lamp body, and the two contacts are used for connecting the contact and the contact ring of the circular ring seat respectively; and a magnetic ring is arranged below the top plate of the lamp holder, and an annular iron sheet is arranged at the corresponding position above theconnecting seat of the lamp body. The down light structure has the main advantages that different lamp bodies can be mounted on the same lamp holder, and installation and replacement are convenient.

Description

technical field [0001] The invention belongs to a downlight structure for being installed on a suspended ceiling. Background technique [0002] Whether in shopping malls or at home, downlights are the most common lighting fixtures; with the development of technology, today's downlights are basically illuminated by LED SMD lamp beads, which have the advantages of energy saving, less space occupation, and less damage. LED downlights have different sizes depending on the power, usually 2.5 inches, 3 inches, 3.5 inches, 4 inches, 5 inches, 6 inches, etc. The LED downlight is installed on the ceiling, and the ceiling structure of the family is usually a gypsum board structure; a circular hole slightly smaller than the diameter of the downlight is opened in the ceiling, and the downlight is embedded in the ceiling; the size of the opening must be the same as that of the downlight. adaptation. [0003] LED downlights do not have independent lamp sockets; when changing the lamp, t...

AI Technical Summary

Problems solved by technology

There are the following defects when changing the downlight: first, due to the ceiling of the gypsum board structure, when the downlight is removed, the scratches with the gypsum board are likely to cause a lot of dust to fall off and easily damage the gypsum board; If the lamp is replaced with a high-power lamp, the hole must be re-dug to fit a larger downlight; Large ones cannot be made smaller, that is, the original high-brightness lamps cannot be replaced with low-brightness lamps
