Description

A type of suspended wall washer downlight Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a suspended wall washer downlight. Background Technology

[0002] Wall washer downlights are recessed ceiling-mounted lighting fixtures that emit downward-facing light. They are directional lighting, meaning only the opposite surface of the light source receives illumination. The beam angle is focused, resulting in concentrated light, strong contrast between light and shadow, highlighting the illuminated object, and high luminous efficacy, creating a quiet atmosphere. Wall washer downlights are generally used as decorative lighting. However, existing wall washer downlights consist of an outer ring and an inner ring. Adjusting the beam angle requires swinging the inner ring, and the beam angle can only be adjusted left or right. This inflexible adjustment, high manufacturing cost, and inconvenient installation hinder mass production and widespread adoption. Therefore, to overcome the shortcomings of existing technology, it is necessary to improve it. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and provide a suspended wall washer downlight with low manufacturing cost and easy-to-adjust illumination angle.

[0004] This utility model is achieved through the following technical solution:

[0005] A suspended wall washer downlight includes an outer ring, a heat sink mounted on the top of the outer ring, a downward-emitting light source mounted on the inner side of the bottom of the heat sink, a suspended middle ring mounted on the inner side of the suspended middle ring, a suspended inner ring mounted on the inner side of the suspended inner ring, a lens mounted on the inner side of the suspended inner ring, an inner arc surface provided on the inner side of the suspended middle ring, and an outer arc surface corresponding to the inner arc surface provided on the outer side of the suspended inner ring.

[0006] Furthermore, the inner arc surface is evenly provided with several arc-shaped protrusions, and both the suspended middle ring and the suspended inner ring are plastic parts.

[0007] Furthermore, a light source bracket for mounting the light source is installed on the inner side of the bottom of the heat sink, and the light source bracket has a slot for mounting the light source.

[0008] Furthermore, the outer side of the suspended ring is provided with several locking blocks, and the inner side of the bottom of the radiator is provided with a slot for installing the locking blocks.

[0009] Furthermore, the outer side of the bottom of the lens is provided with a mounting flange, the inner side of the suspended inner ring is provided with a mounting platform for mounting the mounting flange, and the inner side of the suspended inner ring is provided with a first hook that abuts against the mounting flange.

[0010] Furthermore, the lens has an entrance cavity at its top, and the light source is a COB light source.

[0011] Furthermore, a reflector is installed on the inner side of the outer ring.

[0012] Furthermore, the outer side of the reflector cup is provided with several second hooks, the inner side of the outer ring is provided with a locking strip corresponding to the second hooks, the outer side of the bottom of the reflector cup is provided with a flange, and the inner side of the outer ring is provided with a platform for mounting the flange.

[0013] Furthermore, a mounting spring is installed on the outer side of the outer ring via rivets.

[0014] Furthermore, the upper part of the radiator is provided with several longitudinal heat dissipation fins, and several heat dissipation channels are formed between the heat dissipation fins. The lower part of the radiator is provided with heat dissipation holes that communicate with the heat dissipation channels.

[0015] Compared to existing technologies, this invention features a suspended inner ring installed inside the suspended middle ring, with a lens installed inside the inner ring. The inner side of the suspended middle ring has an inner arc surface, and the outer side of the suspended inner ring has an outer arc surface corresponding to the inner arc surface.
