DESC:FIELD OF THE INVENTION

The present disclosure relates to lighting devices and more particularly, relates to a modular cylindrical downlighting apparatus.

BACKGROUND

Cylindrical downlights are a type of lighting device that are installed on a ceiling and have both the residential and commercial applications. A typical cylindrical downlight includes an outer cylindrical structure with a light source enclosed within the outer cylindrical structure. The lighting source includes different kinds of down lights, like lens type, reflector type, honeycomb type, etc. For each lighting device, there is a different type of outer cylindrical structure and hence a different cylindrical downlight. For instance, the honeycomb type light and the lens type down light have different housings and to change the honeycomb down light with other down light, the housing is also changed. The replacement of a whole cylindrical down light increases the monetary burden due to total replacement cost, new assembly cost, etc. Additionally, the cylindrical down lights are not easily maintained due to the compact design that demands total replacement.

Therefore, there is a need to provide a modular cylindrical downlighting apparatus that can overcome the at least above-mentioned shortcomings of the existing switch regulator assemblies.
