Description

MODULAR LIGHTING SYSTEM TECHNICAL FIELD
The present disclosure generally relates to modular lighting system, and more particularly to an installation and assembly methods comprising one or more downlights.
BACKGROUND
A downlight is a light fitting and is exceptional for many uses in both domestic and commercial built environments. The downlights are significantly effective to create zones, navigate around the space and highlight the key pieces such as art. The downlights can provide in-fill light as well as task lighting and hence are effective when used with a combination of other architectural and decorative fittings in a layered lighting schemes. These light fittings are popular due to their aesthetics and further due to the divergent ways they can be employed to create a variety of lighting effects.
The assembly of wide variety of downlights from a common sub-assembly is a challenge and not an easy task. Conventional downlights available in market are manufactured in such a way that, all the parts of it are integrated. As a result, such downlights are not customizable in nature.
Another challenge is the creation of downlight with different installation types as well as different appearances and multi material assemblies. Due to creation of such downlight with different installation types as well as different appearances and multi material assemblies, a wide variety of finished assembled products are stocked in a warehouse. Such finished assembled products take up more warehousing space and has a higher stocked material value. Another problem for creation of such downlight, is slow production time for non-common line items and need of skilled labour to do the final assembly at dispatch warehouse rather than at production/fabrication.
Conventional downlights available in market has lights being manufactured at component level and hence it is difficult to breaks lights, down into easy to assemble sub assembly levels, which imposes another challenge for modular and customizable downlights.
Existing solutions for the above-mentioned problems, for downlights or the surface mount lights utilising LEDs use a light engine, without any housing incorporated in the engine.
Existing solutions for the above-mentioned problems, for downlights or the surface mount lights utilising LEDs are configured in such a way, that they mount the LED directly to the surface mount housing. Such solutions, have long lead time to make the lights and produce the final lights from component level at the manufacturing factory.
Thus, there exists a need for a solution to overcome above-mentioned deficiencies.
SUMMARY OF THE INVENTION

Embodiments of the present disclosure, disclose utilising the downlight as the light engine. Further, the use of existing heatsink, lens, and assembled LED module for the disclosed modular lighting system allows for using existing downlight stock for lower volume surface light stock. The driver and LED are most expensive part of the assembly and hence using the existing parts, results in saving stock that is held in that area is paramount.
The difference from the existing solutions, is that the traditional lighting system in the surface mount are completely made from scratch and no parts such as heatsink, lens, and assembled LED module are utilized. Further, the traditional lighting system use a light source or a light engine with different attachment method. That light engine is still separate to the main downlight range. Embodiments of the present disclosure, disclose the main downlight as the light engine and thereby cutting down the stock in warehouse. Furthermore, the ability of keeping the LED module attached in the downlight to the downlights heatsink means no complex rework is required.
Referring again to Figure 1, the circular driver as shown is configured to fit into the tube housing. The circular driver has a slimline connector and thereby enables to quickly connect to mounting sub assembly wiring. In one embodiment, the circular driver can be swapped between different dimmable and driver types easily with easy connectors between the downlight and driver and the driver and mounting subassembly.
In one embodiment, the downlight is held into the outer housing tube via use of a front retaining ring as shown in Figure 1. This front retaining ring may also allow additional filters or additional beam changing optics to be applied to the assembly.
Referring to Figure 2, a schematic diagram indicative of fascia ring that is required for standard recessed ceiling use, which is removable in nature, and downlight springs removed for tube insertion. Embodiments of the present disclosure, disclose a downlight, that has a design such that the springs and lip of the fascia are easily removed. In one example embodiment, the downlight as disclosed are of different brightness, different CCT and different fascia colour.
The mounting sub assembly is inserted and fixed to the tube. The mounting sub assembly can be of different mounting type. Examples of the mounting type include, but not limited to track mounted, adjustable surface mount, non-adjustable surface mount, and pendant mount. The mounting sub assembly can be easily swapped from one tube to another tube.
Embodiments of the present disclosure, disclose the modular lighting system and such disclosed system can create a large range of several finished options from holding small quantity of parts and sub-assemblies on hand. The modular lighting system disclosed allows for greater variety of customizable lights by using less and existing parts such as drivers, rings, heatsink, lens, and assembled LED module.
In accordance with embodiments discussed herein, the exemplary modular lighting system is configured to be able to take existing downlights to be installed as a key component into a surface mount assembly.
In accordance with embodiments discussed herein, the exemplary modular lighting system is configured for utilising the existing downlights driver, heatsink and LED module without any complex electrical or mechanical rework required.
In accordance with embodiments discussed herein, the exemplary modular lighting system comprises downlights that can be of different output power, CCT or may have a different type of dimmable driver.
In accordance with embodiments discussed herein, the exemplary modular lighting system discloses a Surface mount assembly that can be changed to a variety of mounting options such as Track mounted assembly, adjustable surface mount assembly, non-adjustable surface mount assembly, and pendant mount assembly.
Figure 3 illustrates different visual appearance that can be easily configured for the modular lighting system, in accordance with an embodiment of the present invention.
In accordance with embodiments discussed herein, the exemplary modular lighting system discloses a surface mounted downlight that can utilise different tube lengths and finishes to change appearance of finished light.
In accordance with embodiments discussed herein, the exemplary modular lighting system discloses a surface mounted downlight that can be assembled with multiple materials without affecting assembly or output.
In accordance with embodiments discussed herein, the exemplary modular lighting system discloses a surface mounted downlight that is able to easily add secondary beam changing components to the assembly such as filters or other fascias.
Figure 4 illustrate several components/parts/items of the modular lighting system and its description, that is configured for utilizing and converting the existing fully finished recessed downlight into different innovative surface mount assembly products. Each part is labelled with reference numeral 1-11. The part number 1 is the ceiling mount plate which is configured to attach the assembly to surface (part of mounting sub assembly). The part number 2 is hinge RT 100, which is the part of mounting sub assembly. The part number 3 is the hinge mount plate which is the part of mounting sub assembly. The part number 4 illustrates the mount assembly screws, which are M4 socket drive button to fix mounting sub assembly to tube. The part number 5 illustrates a tube which is a surface mount tube.

The part number 6 illustrates a circular driver which is a part of downlight subassembly to be used in downlight assembly. The part number 7 illustrates a heatsink expander which is inserted into the downlight subassembly and tube to transfer thermal energy to tube (parts).
The part number 8 illustrates a JST 2 Pin connector which is a DC connector part of downlight subassembly.
The part number 9 illustrates a downlight heatsink which is a part of downlight sub assembly used to transfer thermal energy away from LED chip.
The part number 10 illustrates a downlight front bell/fascia which is a part of downlight subassembly used for downlight mounting into ceiling, variety of colour and surface finished are available.
The part number 11 illustrates a retaining ring for surface tube assembly and part threads into tube and hold downlight in place by locking the downlight front fascia against the tube.
The advantage of the disclosed modular lighting system is that the system allows a wide variety of downlights to be assembled from common sub-assemblies. The modular lighting system allows for a creation of a light with different installation types as well as different appearances and multi material assemblies. This solves the problem of holding stock of a wide variety of finished assembled products which takes up more warehousing space and has a higher stocked material value. Further, the disclosed modular lighting system solves the problem of slow production time for non-common line items as this method allows for faster dispatch by using non-skilled labour to do the final assembly at dispatch warehouse rather than at production/fabrication. The modular lighting system breaks lights down into easy to assemble sub-assembly levels, rather than the light being manufactured at component level.
While certain present preferred embodiments of the disclosure have been illustrated and described herein, it is to be understood that the disclosure is not limited thereto. Clearly, the disclosure may be otherwise variously embodied, and practiced within the scope of the following claims.
