A modular lighting fixture that is capable of receiving interchangeable functional modules includes a body having a main portion and a second portion. The main portion has a hollow interior defining an interior space extending in a longitudinal direction from a first open end of the main portion to a second end of the main portion. The second portion is provided at the first end and extends outwardly in a transverse direction, wherein the interior space is configured to receive and retain a functional module configured to provide non-light emitting function. A light emitting means is provided on the second portion of the body and configured to emit light.

A baffle component for a luminaire includes a portion of opaque material that forms a front surface and a back surface as major surfaces. The front surface includes multiple ridges. The material also includes a top surface and a bottom surface, and a first end surface and a second end surface. The first end surface includes a first coupling feature, and the second end surface includes a second coupling feature that is configured to engage the first coupling feature of a second baffle component that is substantially identical to the baffle component. A baffle for a luminaire includes a plurality of such components. The baffle components engage with one another, with the first coupling feature of each of the baffle components engaging with the second coupling feature of another of the baffle components, to form a shape that surrounds a central opening of the luminaire.

A spotlight lamp includes a housing, a light emitting module, a lens, and an anti-glare ring. The housing has an opening. The light emitting module and the lens are both arranged inside the housing. The anti-glare ring is connected to the housing by a detachable snap-fit structure, and blocks an edge of the opening. The lens abuts between the light emitting module and the anti-glare ring. The disassembly and assembly process of the spotlight lamp provided by the embodiments of the present disclosure is very simple so that it is convenient for users to replace the lens to adjust the light emitting range.

The present disclosure discloses a light fixture, which includes a light body and elastic mounting members. The light body includes a light housing and a limiting element, the limiting element is connected to the light housing, a limiting space is enclosed by the light housing and the limiting element, one end of the limiting space is provided with a mounting opening, the limiting element has a matching notch, the matching notch is formed by extending from the mounting opening to an inside of the limiting element, and the light housing recesses to be provided with a limiting slot that communicates with the limiting space; and each elastic mounting member includes a clamping portion and a mounting portion, the clamping portion includes a base body and an elastic clip, the elastic clip is elastically connected to the base body.

A non-glare luminaire includes a toroidal-shaped light engine having light emitting diodes (LEDs) disposed about the light engine in a radial pattern. The light engine has an axial direction that is at least substantially orthogonal to the surface of the light engine. An anti-glare ring is disposed proximate the light engine and includes reflectors arranged in a radial pattern. Each reflector is configured to reflect tangentially oriented light from at least one of the LEDs substantially along the axial direction. The luminaire also includes a toroidal integrated optic (TIO), which is made up of a total internal reflectance (TIR) lens that is coupled with a light guide. The TIO optic has a toroidal lens portion having a light entrance side that receives light from the LEDs and the reflectors. The optic collimates the light received from the LEDs and the reflectors and emit the light via a light exit side.
