Description

Technical Field

[0001] This invention belongs to the field of home lighting technology and relates to a smart home lighting device. Background Technology

[0002] With increasing awareness of energy conservation and environmental protection, energy-saving lighting devices, represented by LEDs, have been widely used in home settings. LED lamps have advantages such as high luminous efficacy, long lifespan, and low energy consumption, but they are quite sensitive to operating temperature, and heat dissipation performance directly affects luminous efficacy and lifespan. Traditional chandeliers, ceiling lights, or floor lamps typically use a fixed structure. Lighting devices generate a lot of heat during prolonged operation, especially energy-saving lighting devices using LED light sources, whose light-emitting surfaces and internal electronic components have high requirements for heat dissipation. Most existing lamps rely on natural convection or simple ventilation holes for heat dissipation, which has low heat dissipation efficiency. Long-term high-temperature operation can easily lead to accelerated light decay and shortened lifespan. Traditional lamps still occupy a lot of space when not in use, especially chandeliers or large decorative lights, which are often hung in the center of the room or above the dining table. They are prone to collisions when moving large furniture or during indoor activities, causing damage to the lamps and even safety hazards.

[0003] To address the aforementioned problems, this invention proposes a smart home lighting device. Summary of the Invention

[0004] To address the problems existing in the background technology, the present invention proposes a smart home lighting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a smart home lighting device, comprising a first fixing block and a second fixing block, wherein the second fixing block is movable relative to the first fixing block; the first fixing block is connected to a first light-emitting unit, and the second fixing block is connected to a second light-emitting unit; the first light-emitting unit comprises a plurality of first lamp post assemblies hinged in sequence, and the second light-emitting unit comprises a plurality of second lamp post assemblies hinged in sequence; the first lamp post assembly and the second lamp post assembly correspond one-to-one, and the first lamp post assembly is hinged to the corresponding second lamp post assembly; the second fixing block moves closer to the first fixing block, causing the first light-emitting unit and the second light-emitting unit to change to a retracted state;

[0006] The first fixing block is fixedly connected to the upper housing, and the second fixing block is fixedly connected to the lower housing. Fans are installed inside both the upper and lower housings to dissipate heat from the first and second light-emitting units.

[0007] Furthermore, the first lamp post assembly includes a first light-emitting surface and a first support rod. The first light-emitting surface is disposed on the first support rod, and two adjacent first support rods are connected by a first connecting block; one of the first connecting blocks is fixedly connected to a first fixing block.

[0008] The second lamp post assembly includes a second light-emitting surface and a second support rod. The second light-emitting surface is disposed on the second support rod, and two adjacent second support rods are connected by a second connecting block; one of the second connecting blocks is fixedly connected to a second fixing block.

[0009] Furthermore, the second support rod is located outside the corresponding first support rod.

[0010] Furthermore, both the first and second lamp post assemblies are provided with air intakes, and both the first and second light-emitting units are provided with gas channels. When the upper and lower housings are pressed together, the space enclosed by the upper and lower housings is connected to the air intakes through the gas channels.

[0011] Furthermore, the gas channel includes a slot, a ventilation cavity, a connecting channel, an air duct, and a first ventilation hole;

[0012] Both the upper and lower housings are provided with slots;

[0013] Both the first fixing block and the second fixing block have ventilation chambers that communicate with the slot.

[0014] Both the second connecting block and the first connecting block are provided with connecting channels; the venting cavity is connected to the corresponding connecting channel;

[0015] Both the second support rod and the first support rod are provided with air ducts; the air ducts are connected to the connecting channel;

[0016] Both the second support rod and the first support rod have a first vent hole that connects the air intake to the air duct.

[0017] Furthermore, both the second support rod and the first support rod are fixedly connected to a guide plate, and the air intake is disposed on the guide plate.

[0018] Furthermore, the fan is used to exhaust the air between the upper and lower housings.

[0019] Furthermore, both the second support rod and the first support rod are fixedly connected to a hinge shaft at their ends. The hinge shaft has an annular groove and a second vent hole. The second vent hole connects the annular groove and the air duct. The annular groove is connected to the corresponding connecting channel.

[0020] Compared with the prior art, the present invention has the following beneficial effects: In use, the upper shell and the lower shell are separated, the fan is started, and external air enters from the gap between adjacent support rods, flows through the surface of the support rods and carries away heat, thereby achieving efficient heat dissipation, reducing the operating temperature and extending the service life.

[0021] In its stowed state, the first and second light-emitting units are folded horizontally and close to the ceiling, keeping the lighting device away from the ground, reducing space occupation and avoiding damage when moving large furniture.

[0022] When the device is folded down, the upper and lower housings fit together, the fan starts, and outside air enters the gas channel through the air intake, carrying away dust from the surface of the light-emitting surface, achieving automatic cleaning and ensuring the subsequent lighting effect.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1-11 As shown, the technical solution adopted by the present invention is as follows: A smart home lighting device includes a first fixing block 3, a second fixing block 4, a first light-emitting unit, and a second light-emitting unit. The second fixing block 4 is movable relative to the first fixing block 3. Specifically, in this embodiment, the first fixing block 3 is fixedly installed on the indoor ceiling, and an electric push rod 1 is fixedly connected to the first fixing block 3. The telescopic end of the electric push rod 1 is fixedly connected to the second fixing block 4, and the electric push rod 1 is used to drive the second fixing block 4 to move up and down relative to the first fixing block 3.

[0037] The first light-emitting unit is connected to the first fixing block 3. The second light-emitting unit is connected to the second fixing block 4. The first light-emitting unit includes multiple first lamp post assemblies that are hinged in sequence, and the second light-emitting unit includes multiple second lamp post assemblies that are hinged in sequence. The first lamp post assembly and the second lamp post assembly correspond one-to-one, and the middle part of the first lamp post assembly and the middle part of the second lamp post assembly are hinged to each other. When the second fixing block 4 moves closer to the first fixing block 3, the first light-emitting unit and the second light-emitting unit change to a retracted state, that is, both the first lamp post assembly and the second lamp post assembly change to a horizontal state.

[0038] The first lamp post assembly includes a first luminous surface and a first support rod 6, with the first luminous surface disposed on the outer surface of the first support rod 6. Two adjacent first support rods 6 are hinged together by a first connecting block 8. Each first support rod 6 is hinged to a corresponding first connecting block 8. One of the first connecting blocks 8 is fixedly connected to a first fixing block 3.

[0039] The second lamp post assembly includes a second luminous surface and a second support rod 5. The second luminous surface is disposed on the outer surface of the second support rod 5. Two adjacent second support rods 5 are hinged together by a second connecting block 7. One of the second connecting blocks 7 is fixedly connected to a second fixing block 4.

[0040] In this embodiment, six first support rods 6 and six second support rods 5 are provided. The six first support rods 6 are sequentially hinged together by the first connecting block 8 to form a closed loop. The six second support rods 5 are sequentially hinged together by the second connecting block 7 to form a closed loop.

[0041] The second support rod 5 is located outside the corresponding first support rod 6. That is, in each pair of corresponding first support rods 6 and second support rods 5, the second support rod 5 is located outside the first support rod 6, and the middle parts of the two are hinged to each other.

[0042] The first fixing block 3 is fixedly connected to the upper housing 2, and the second fixing block 4 is fixedly connected to the lower housing 9. Both the upper housing 2 and the lower housing 9 are equipped with fans 10.

[0043] The fan 10 is used to draw air outwards from between the upper housing 2 and the lower housing 9. Specifically, when the fan 10 inside the upper housing 2 is activated, the air inside the upper housing 2 flows upwards. When the fan 10 inside the lower housing 9 is activated, the air inside the lower housing 9 flows downwards.

[0044] When the first and second light-emitting units are in use, outside air flows into the space between the upper housing 2 and the lower housing 9 through the gaps between the first and second light pole assemblies, the gaps between two adjacent first light pole assemblies, and the gaps between two adjacent second light pole assemblies, and then flows out through the upper housing 2 and the lower housing 9. This process dissipates heat from the first and second light pole assemblies.

[0045] Both the second support rod 5 and the first support rod 6 are equipped with air intakes 18. The air intake 18 is located on one side of either the first or second light-emitting surface. Both the first and second light-emitting units have internal gas channels. When the upper housing 2 and the lower housing 9 are abutted together (in their retracted state), the space enclosed by the upper housing 2 and the lower housing 9 is connected to the air intake 18 through the gas channels. At this time, the fan 10 is activated, causing air from the air intake 18 to flow through the gas channels into the space enclosed by the upper housing 2 and the lower housing 9 and then be discharged. This cleans both the first and second light-emitting surfaces.

[0046] Specifically, the gas passage includes a slot 13, a ventilation chamber 12, a connecting channel, an air duct 16, and a first ventilation hole 17. Wherein:

[0047] Both the lower end face of the upper housing 2 and the upper end face of the lower housing 9 are provided with slots 13. When the upper housing 2 and the lower housing 9 are fitted together, the slots 13 of the two together form an airflow communication port.

[0048] Both the first fixing block 3 and the second fixing block 4 have ventilation chambers 12 that communicate with the corresponding slots 13. When the first fixing block 3 and the second fixing block 4 are fitted together, the two ventilation chambers 12 are aligned.

[0049] Both the second connecting block 7 and the first connecting block 8 have connecting channels. Specifically, the first connecting block 8 has a first connecting channel 14, and the second connecting block 7 has a second connecting channel 15. The venting cavity 12 on the upper housing 2 communicates with the first connecting channel 14. The venting cavity 12 on the lower housing 9 communicates with the second connecting channel 15.

[0050] Both the second support rod 5 and the first support rod 6 have internal air ducts 16. The air duct 16 on the second support rod 5 is connected to the second connecting channel 15. The air duct 16 on the first support rod 6 is connected to the first connecting channel 14.

[0051] Both the second support rod 5 and the first support rod 6 are provided with a first vent hole 17. One end of the first vent hole 17 is connected to the ventilation channel 16, and the other end is connected to the air intake 18.

[0052] Furthermore, a guide plate 11 is fixedly connected to one side of both the second support rod 5 and the first support rod 6. An air intake 18 is disposed on the guide plate 11 and is connected to the air duct 16 through the first vent 17. The guide plate 11 is located on one side of the first light-emitting surface or the second light-emitting surface, and the air intake 18 is used to guide the airflow to clean the light-emitting surface.

[0053] like Figure 9 , Figure 10 as well as Figure 11 As shown, both the second support rod 5 and the first support rod 6 are fixedly connected to hinge shafts at their ends. The second support rod 5 is hinged to the second connecting block 7 via the hinge shaft, and the first support rod 6 is hinged to the first connecting block 8 via the hinge shaft. An annular groove 19 and a second vent hole 20 are provided on the hinge shaft. The second vent hole 20 connects the annular groove 19 and the air duct 16. The annular groove 19 is connected to the corresponding connecting channel. The annular groove 19 remains connected to the connecting channel, thereby ensuring unobstructed gas passage.

[0054] Working principle: such as Figure 1 , Figure 2 As shown, the electric push rod 1 drives the second fixed block 4 to move downwards away from the first fixed block 3, causing the first and second lamp post assemblies to change to a vertical position, and the upper housing 2 to separate from the lower housing 9. The first luminous surface of the first support rod 6 and the second luminous surface of the second support rod 5 illuminate outwards. The electric push rod 1 can drive the second fixed block 4 to stop at different heights, thus achieving different lighting states.

[0055] At this time, the fans 10 inside the upper housing 2 and the lower housing 9 can be activated. The fan 10 inside the upper housing 2 draws air upwards, and the fan 10 inside the lower housing 9 draws air downwards. External air enters the area between the upper housing 2 and the lower housing 9 through the gaps between the first support rod 6 and the second support rod 5, the gaps between two adjacent first support rods 6, and the gaps between two adjacent second support rods 5. It flows over the surfaces of the first support rods 6 and the second support rods 5, carrying away the heat generated by the first light-emitting surface, the second light-emitting surface, and the internal electronic components. This achieves heat dissipation for the first and second light-emitting units, thereby extending their service life.

[0056] When storage is required, the electric push rod 1 drives the second fixing block 4 to move upwards closer to the first fixing block 3. Both the first and second lamp post assemblies shift towards a horizontal position, causing the first and second light-emitting units to gradually fold to a near-horizontal state, close to the ceiling. This continues until the first fixing block 3 is attached to the second fixing block 4, and the upper housing 2 and lower housing 9 are joined together. Figure 5 , Figure 6 As shown.

[0057] At this time, the slot 13 on the lower end face of the upper shell 2 aligns with the slot 13 on the upper end face of the lower shell 9, forming an airflow communication port. Simultaneously, the ventilation chamber 12 on the first fixing block 3 aligns and connects with the ventilation chamber 12 on the second fixing block 4.

[0058] The fan 10 inside the upper housing 2 and lower housing 9 is activated, drawing air outward from between them and creating negative pressure in the area. Under this negative pressure, external air enters the gas channel through the intake port 18. Specifically, outside air enters the air duct 16 through the intake port 18 and the first vent 17. Air in the air duct 16 enters the connecting channel through the second vent 20 and the annular groove 19, and then flows into the corresponding air duct 16 or vent chamber 12. Air in the first connecting channel 15 within the first connecting block 7 connected to the upper housing 2 and air in the second connecting channel 14 within the second connecting block 8 connected to the lower housing 9 flow into the upper housing 2 or lower housing 9 through the vent chamber 12 and slot 13, and is finally discharged by the fan 10.

[0059] During this process, the airflow carries away the dust from the surfaces of the first and second light-emitting surfaces, achieving automatic cleaning and ensuring subsequent lighting effects.

[0060] When folded up, the first and second light-emitting units are far from the ground, reducing space occupation and avoiding damage when moving large furniture.

[0061] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
