Technical Field
[0001] This utility model relates to the field of lighting technology, and in particular to a downlight that is easy to assemble. Background Technology
[0002] With social development and continuous advancements in science and technology, the variety of lighting fixtures on the market is increasing. Among them, downlights are a common type of lighting fixture in people's daily lives. Downlights are generally embedded inside the ceiling, emitting soft light from above, enriching the visual effect and creating a warm atmosphere, thus gaining popularity.
[0003] Modern downlights generally employ the following structure: an aluminum alloy housing, a light source substrate, and a driver power supply box. The aluminum alloy housing has an open-top cavity. An LED chip capable of emitting light when powered is mounted on the upper surface of the light source substrate. The light source substrate is fixed to the bottom of the cavity with screws, and the light emission direction of the LED chip faces the opening of the cavity. The driver power supply box is fixed to the bottom outer wall of the aluminum alloy housing with screws. The driver power supply box contains a driver power supply, which is electrically connected to the light source substrate through wires.
[0004] While the aforementioned downlights can meet users' lighting needs, the light source substrate is mounted at the bottom of the aluminum alloy housing. To avoid the risk of electrical leakage, the driver power supply needs to be installed separately inside an insulated driver power supply box. When the driver power supply is connected to the external mains power, it converts the 220V AC power into low-voltage DC power, which then powers the light source substrate. This structure necessitates the use of a driver power supply and a driver power supply box for the downlights, thus increasing their production cost.
[0005] In addition, during the production process of the aforementioned downlights, workers need to use screws to lock the power board and driver power box to the aluminum alloy housing, which makes the assembly relatively complicated and affects the production and processing of the downlights. Utility Model Content

[0037] Reference Figures 1 to 12 and mainly refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 9 and Figure 10A downlight that is easy to assemble, according to certain embodiments of the present invention, is sometimes simply referred to as a "downlight". The downlight includes an outer shell 100, an inner shell 200, and a light source substrate 300. The outer shell 100 has a first receiving cavity 110 inside, with an open upper portion. The inner shell 200 has a second receiving cavity 210 inside, and a light outlet 211 communicating with the second receiving cavity 210 is opened at the upper portion of the inner shell 200. The inner shell 200 is detachably fitted into the first receiving cavity 110, and a first snap-fit structure is provided between the inner shell 200 and the outer shell 100. Each set of first snap-fit structures includes a first elastic hook and a first slot that can engage with each other. In this embodiment, the first slot is formed on the inner wall of the first receiving cavity 110, and the first elastic hook is disposed on the outer peripheral wall of the inner shell 200. When the inner shell 200 is embedded in the first receiving cavity 110 of the outer shell 100, the first elastic hook engages with the corresponding first slot, thereby fixing the inner shell 200 in the first receiving cavity 110 of the outer shell 100. The upper surface of the light source substrate 300 is provided with a light source 310 that can emit light when energized. In this embodiment, the light source 310 is an LED light-emitting chip. The light source substrate 300 is snap-fitted to the lower part of the second receiving cavity 210, and the light emission direction of the light source 310 faces the light emission port 211.
[0038] In this embodiment, the downlight has one or more first snap-fit structures between the inner housing 200 and the outer housing 100. During assembly, the worker can insert the inner housing 200 into the first receiving cavity 110 of the outer housing 100. At this time, the inner housing 200 and the outer housing 100 are snapped together by the first snap-fit structures. The worker can also snap-fit the light source substrate 300 into the lower part of the second receiving cavity 210 of the inner housing 200. In this process, the worker does not need to tighten the screws to lock the various parts of the downlight together, which makes the assembly of the downlight simpler and faster, greatly improves the assembly efficiency of the downlight, and helps to reduce the production cost of the downlight.
[0039] It should be noted that in the above embodiments, a first snap-fit structure is provided between the inner shell 200 and the outer shell 100. However, in other embodiments of this utility model, multiple sets of first snap-fit structures are provided between the inner shell 200 and the outer shell 100. Multiple first slots of the multiple sets of first snap-fit structures are formed on the inner wall of the first receiving cavity 110. The multiple first slots are sequentially connected and form an annular groove arranged circumferentially around the inner wall of the first receiving cavity 110. Multiple first elastic hooks of the multiple sets of first snap-fit structures are arranged at intervals on the outer peripheral wall of the inner shell 200. When the inner shell 200 is fitted into the first receiving cavity 110 of the outer shell 100, the multiple first elastic hooks engage with the annular groove. Therefore, the multiple sets of first snap-fit structures can firmly lock the inner shell 200 and the outer shell 100 together.
[0040] It is understood that in the above embodiments, the first slot of the first snap-fit structure is opened on the inner wall of the first receiving cavity 110, and the first elastic hook is disposed on the outer peripheral wall of the inner shell 200. However, in other embodiments of this utility model, the first elastic hook and the first slot of the first snap-fit structure can also adopt other structures, such as the first slot being opened on the outer peripheral wall of the inner shell 200, and the first elastic hook being disposed on the inner wall of the first receiving cavity 110. When the inner shell 200 is embedded in the first receiving cavity 110 of the outer shell 100, the first elastic hook can also snap into the corresponding first slot, thereby fixing the inner shell 200 inside the first receiving cavity 110 of the outer shell 100.
[0041] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9 A downlight that is easy to assemble according to certain embodiments of the present invention includes a diffuser plate 400 and a first reflector cup 410. The diffuser plate 400 is snapped into the interior of a second receiving cavity 210. The first reflector cup 410 is located inside the second receiving cavity 210. One end of the first reflector cup 410 is covered with the outer periphery of the light source 310, and the other end of the first reflector cup 410 abuts against the diffuser plate 400. The diffuser plate 400 covers the opening at the other end of the first reflector cup 410 away from the light source 310. By using a first reflector cup 410 to cover the outer periphery of the light source 310, and a diffuser plate 400 to cover the opening at the other end of the first reflector cup 410 away from the light source 310, the first reflector cup 410 can better reflect the light emitted by the power source 310 to the diffuser plate 400. After the light passes through the diffuser plate 400, it is emitted from the light outlet 211, which can enhance the light efficiency of the downlight and make the downlight brighter. Moreover, after the light emitted by the power source 310 passes through the diffuser plate 400, the light output of the downlight can be more uniform and softer, and it is not easy to form glare.
[0042] In some embodiments of this utility model, the first reflector 410 is constructed by folding reflective paper. By using folded reflective paper to construct the first reflector 410, not only can the light emitted by the light source 310 be more concentrated in illuminating the diffuser plate 400, but the cost of the first reflector 410 can also be reduced, thereby reducing the production cost of the downlight in this embodiment.
[0043] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9To facilitate the installation of the diffuser plate 400 into the inner housing 200, in some embodiments of this invention, the inner housing 200 is provided with a plurality of first snap-fit grooves 220. All the first snap-fit grooves 220 are located in the middle of the inner sidewall of the second receiving cavity 210, and are arranged circumferentially around the inner housing 200. When the diffuser plate 400 is installed inside the second receiving cavity 210, its outer periphery engages with all the first snap-fit grooves 220. By adopting the above structure, when the diffuser plate 400 is installed into the inner housing 200, it is only necessary to squeeze the diffuser plate 400 so that its periphery engages with all the first snap-fit grooves 220, which simplifies the operation and greatly improves the assembly efficiency of the downlight.
[0044] It should be noted that in the above embodiments, there are multiple first snap-fit slots 220, which are arranged at intervals in the middle of the inner wall of the second receiving cavity 210. In other embodiments of this invention, there is one first snap-fit slot 220, which is located in the middle of the inner wall of the second receiving cavity 210; or there are two first snap-fit slots 220, which are arranged at intervals in the middle of the inner wall of the second receiving cavity 210. The specific arrangement can be determined according to actual needs.
[0045] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 9One embodiment of the present invention provides an easily assembled downlight including a second reflector 420. A second snap-fit structure is provided between the inner housing 200 and the second reflector 420. The second snap-fit structure includes a second elastic hook 421 and a second slot 230 that can engage with each other. The second elastic hook 421 is disposed in the inner housing 200, and the second slot 230 is disposed in the second reflector 420; alternatively, the second elastic hook 421 is disposed in the second reflector 420, and the second slot 230 is disposed in the inner housing 200. When the second reflector 420 is embedded inside the second receiving cavity 210, one end of the second reflector 420 abuts against the surface of the diffuser plate 400 away from the light source 310, and the second elastic hook 421 of the second snap-fit structure engages with the corresponding second slot 230. By adopting the above structure, when the second reflector 420 is installed in the inner housing 200, it is only necessary to press the second reflector 420 into the second receiving cavity 210, and the second elastic hook 421 can engage with the corresponding second slot 230, thereby achieving the connection and fixation between the second reflector 420 and the inner housing 200. This makes assembly simpler and more efficient, helping to improve the assembly efficiency of the downlight. Furthermore, by setting the second reflector 420 inside the inner housing 200, the second reflector 420 can more concentratedly illuminate the target area with the light emitted from the diffuser plate 400, improving the light utilization rate of the downlight.
[0046] In some embodiments of this utility model, the number of second snap-fit structures between the inner housing 200 and the second reflector 420 is three sets. The second elastic hooks 421 of each of the three sets of second snap-fit structures are all located at the end of the outer peripheral wall of the second reflector 420 away from the diffuser plate 400. The three elastic hooks 421 are evenly spaced around the outer peripheral wall of the second reflector 420. The second slots 230 of the three sets of second snap-fit structures are evenly spaced on the upper part of the side wall of the inner housing 200. When the second reflector 420 is installed inside the second receiving cavity 210, the three elastic hooks 421 are snapped into the three second slots 230 in a one-to-one correspondence. By adopting the above structure, the connection between the inner housing 200 and the second reflector 420 can be made more secure.
[0047] Reference Figure 1 , Figure 2 , Figure 4 , Figure 8 , Figure 11 and Figure 12A downlight with easy assembly according to certain embodiments of the present invention includes two side spring members 500. The side spring members 500 have a first torsion arm portion 510 and a second torsion arm portion 520. The lower outer sides of the left and right sides of the inner housing 200 are provided with limiting grooves 240 that can be adapted to the first torsion arm portion 510. The left and right side walls of the outer housing 100 are provided with communication openings 120 that correspond one-to-one with the two limiting grooves 240. The two side spring members 500 are arranged one-to-one on the left and right sides of the outer housing 100. The first torsion arm portion 510 of the side spring member 500 located on the left side passes through the communication opening 120 on the left side of the outer housing 100 and is engaged with the limiting groove 240 on the left side of the inner housing 200. The first torsion arm portion 510 of the side spring member 500 located on the right side passes through the communication opening 120 on the right side of the outer housing 100 and is engaged with the limiting groove 240 on the right side of the inner housing 200. By adopting the above structure, the two side springs 500 can be snapped into the limiting grooves 240 on the left and right sides of the inner housing 200 in a one-to-one correspondence. This eliminates the traditional installation method of fixing the two side springs 500 to the opposite side walls of the downlight with bolts, which helps to further improve the assembly efficiency of the downlight.
[0048] Reference Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 10 To facilitate better installation of the light source substrate 300 into the second receiving cavity 210 of the inner housing 200, in some embodiments of this invention, the inner housing 200 is provided with two substrate engaging slots 250 located inside the second receiving cavity 210. The two substrate engaging slots 250 are arranged correspondingly on the lower parts of opposite side walls of the second receiving cavity 210. When the light source substrate 300 is installed inside the second receiving cavity 210, both ends of the light source substrate 300 are engaged with the two substrate engaging slots 250. By adopting the above structure, when installing the light source substrate 300, the manufacturer only needs to press the light source substrate 300 into the second receiving cavity 210 and ensure that both ends of the light source substrate 300 are engaged with the two substrate engaging slots 250. This simple and convenient operation helps improve the assembly efficiency of the downlight.
[0049] Reference Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 and Figure 10In some embodiments of this utility model, the inner shell 200 is an insulating component, and the outer shell 100 is a metal component. Specifically, the inner shell 200 is a plastic component integrally injection molded from plastic, while the outer shell 100 is an aluminum alloy shell component formed by die casting of aluminum alloy with good thermal conductivity. A connecting hole 260 is provided at the bottom of the inner shell 200, and the outer shell 100 has an abutment portion 130 located at the bottom of the inner wall of the first receiving cavity 110. The abutment portion 130 and the outer shell 100 are an integral structure. The inner shell 200 is installed inside the first receiving cavity 110, and the abutment portion 130 passes through the connecting hole 260 and abuts against the lower surface of the light source substrate 300. By adopting the above structure, the insulating inner shell 200 can isolate the light source substrate 300 and the outer shell 100, achieving good leakage prevention. Moreover, the heat generated when the light source 310 is powered on can be transferred to the light source substrate 300, which then transfers the heat to the contact part 130. Finally, the contact part 130 transfers the heat to the entire outer shell 100, which can quickly dissipate the heat to the outside. Thus, the downlight of this embodiment can dissipate heat to the light source 310 through the outer shell 100, greatly improving the heat dissipation performance of the downlight of this embodiment. This ensures that when the light source 310 is powered on for a long time, it will not experience light decay or damage due to excessive temperature, thus extending the service life of the light source 310.
[0050] In some embodiments of this utility model, an insulating and heat-conducting component 600 is provided between the lower surface of the light source substrate 300 and the abutment portion 130. Specifically, the insulating and heat-conducting component 600 is a PET film made of PET material. By providing an insulating heat-conducting element 600 between the lower surface of the light source substrate 300 and the abutment portion 130, insulation between the light source substrate 300 and the abutment portion 130 can be achieved, preventing leakage current from the light source substrate 300 and its conduction to the abutment portion 130 and the outer casing 100. Therefore, the light source substrate 300 in this embodiment can directly use 220V AC mains power as its power supply without the need for a separate drive power supply to convert 220V AC mains power into low-voltage DC power, which helps reduce the production cost of the downlight. Furthermore, the light source substrate 300 can transfer the heat generated when the light source 310 is powered on to the insulating heat-conducting element 600, which then transfers the heat to the abutment portion 130 and the outer casing 100. This allows the downlight in this embodiment to still dissipate heat from the light source 310 through the outer casing 100, thus ensuring good heat dissipation.
[0051] It should be noted that in the above embodiments, the insulating heat-conducting component 600 is a PET film made of PET material. However, in other embodiments of this utility model, the insulating heat-conducting component 600 can also be made of insulating heat-conducting material, such as an insulating heat-conducting silicone pad. The specific choice can be made according to actual needs.
[0052] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
