Description

Technical Field

[0001] The present invention relates to the field of lighting, specifically to the field of household lighting lamps, and in particular to an energy-saving smart household lighting lamp assembly. Background Art

[0002] Lamps are common lighting appliances in people's lives. They generally use electricity as energy to emit light, provide lighting in the dark at night, and provide supplementary lighting when there is insufficient light on cloudy days. In short, they provide a bright environment.

[0003] A search for energy-saving lamps revealed a Chinese utility model patent, with the authorization publication number CN217684737U. This patent discloses a self-powered fiber-optic sunlight-introduction lighting system. This system uses a sun position sensor and a sunlight intensity sensor to keep the light collector facing the sun. The light collector then directs sunlight into the room, where it generates photovoltaic power and stores energy through solar panels. This system achieves 100% clean energy utilization and energy savings. However, this system still has some shortcomings. Specifically, the solar panels are simply mounted on top of the controller, which occupies a large area and has low power generation efficiency. In daily life, people pursue a sense of warmth and comfort, which is reflected in lighting. During periods of alternating light and dark, such as evening, a certain indoor illumination level is required to ensure a smooth transition between light and dark. If the indoor brightness dims along with the ambient light during these periods, it can cause psychological and emotional discomfort to the occupants. While this patent document achieves energy savings, it fails to maintain the set indoor brightness during the alternating light and dark periods.

[0004] Based on the above, the present invention proposes an energy-saving smart home lighting assembly. Summary of the Invention

[0005] To solve the problems mentioned in the above background, the present invention provides an energy-saving smart home lighting assembly.

[0006] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows.

[0007] An energy-saving smart home lighting assembly includes an external lighting unit arranged outdoors, an internal lighting unit arranged indoors, and an optical fiber arranged between the external lighting unit and the internal lighting unit. The external lighting unit includes a housing, an end of the housing facing away from the exterior wall of a building is transparent, a mounting hole is provided on the end of the housing facing away from the exterior wall of the building, a convex lens is provided in the mounting hole, and a light guide is provided in the housing. The light guide comprises a cylindrical shell, which is open at one end facing the outer convex lens and is provided with an inner convex lens. The input end of the optical fiber extends into the cylindrical shell, and a reflective ring is provided between the input end of the optical fiber and the inner convex lens. The reflective ring is trapezoidal in shape and has an outer diameter that decreases from the open end to the closed end of the cylindrical shell. The outer surface of the reflective ring is provided with a first reflective layer, and a plurality of lamp beads are arranged in an array along the outer periphery of the reflective ring along its own circumferential direction. The external lighting unit also includes photovoltaic panels and batteries. The electricity generated by the photovoltaic panels is stored in the batteries, which power the lamp beads.

[0008] As a further improvement and optimization of the present invention, the external lighting unit includes a fixed base arranged on the outer wall of the building, a rotating frame is rotatably mounted on the fixed base and a first connecting axis formed at the rotating mounting position is perpendicular to the outer wall of the building, the cover shell is rotatably mounted on the rotating frame and a second connecting axis formed at the rotating mounting position is perpendicular to the first connecting axis, and the cover shell is in the shape of a cylindrical shell with an axis centerline perpendicular to the second connecting axis.

[0009] As a further improvement and optimization of the present invention, the photovoltaic panel is arranged in the cover and an avoidance hole for avoiding the light guide is provided on the photovoltaic panel.

[0010] As a further improvement and optimization of the present invention, the external lighting unit further includes a first motor for driving the rotating frame to rotate and a second motor for driving the cover shell to rotate.

[0011] As a further improvement and optimization of the present invention, a sun sensor is provided on the cover. The sun sensor cooperates with the first motor and the second motor to keep the end of the cover away from the outer wall of the building facing the sun.

[0012] As a further improvement and optimization of the present invention, the interior lighting unit includes a lampshade arranged on the indoor ceiling, the lower end of the lampshade is open and provided with a diffuser plate, and a light guide switch is provided in the lampshade.

[0013] As a further improvement and optimization of the present invention, the light guide switch includes a threaded shaft arranged vertically and fixedly disposed in the lampshade, the threaded shaft being in the shape of a hollow shaft and the output end of the optical fiber extending into the threaded shaft, and the light guided by the optical fiber irradiates vertically downward; The external threaded sleeve of the threaded shaft is provided with a sleeve shaft in the shape of a hollow shaft, and a third motor is provided in the lampshade, and the third motor is used to drive the sleeve shaft to rotate; A connecting rod is provided at the bottom of the sleeve shaft, and a reflective cone is provided at the bottom of the connecting rod. The reflective cone is in the shape of a cone with an outer diameter that first increases and then decreases from bottom to top. The reflective cone is coaxial with the threaded shaft. When the sleeve shaft moves upward, the reflective cone moves upward together with it, and the lower end of the threaded shaft can be blocked by the reflective cone.

[0014] As a further improvement and optimization of the present invention, a driven gear is provided on the outside of the sleeve shaft, and a driving gear meshing with the driven gear is provided inside the lampshade, and the axial length of the driving gear is greater than the axial length of the driven gear. In the process of the sleeve shaft rotating and moving, the driving gear and the driven gear remain meshed, and the third motor and the driving gear form a power connection.

[0015] As a further improvement and optimization of the present invention, the outer surface of the reflective cone is provided with a second reflective layer, the inner wall of the lampshade is provided with a third reflective layer, and a lamp is further provided in the lampshade, and the lamp is connected to the household circuit.

[0016] As a further improvement and optimization of the present invention, a light sensor for detecting light intensity is provided indoors; In the evening, as the light outside the building gradually weakens, the light introduced into the room through the optical fiber gradually weakens. At this time, the light guide switch is turned on, and the light intensity in the room is monitored in real time through the light sensor. If the indoor light intensity is lower than the set value, the lamp beads are started, and the light emitted by the lamp beads passes through the first reflective layer to the input end of the optical fiber, and finally shines into the room through the optical fiber, providing more light for the room. The brightness of the lamp beads can be adjusted steplessly. Therefore, as time goes by, the light emitted by the lamp beads continues to increase, so that the indoor brightness remains at the set value.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. This solution can play the following roles through the integrated structure of lamp beads and optical fibers: In the evening, as the light outside the building gradually weakens, the light introduced into the room through the optical fiber gradually weakens. At this time, the light guide switch automatically opens, and the light intensity in the room is monitored in real time by the light sensor. If it is lower than the set value, the lamp beads are activated, and the light emitted by the lamp beads passes through the first reflective layer to the input end of the optical fiber, providing more and stronger light for the room. It should be noted that the lamp beads use stepless brightness adjustment technology, that is, the lamp beads can adjust the light they emit according to the light intensity in the room. For example, if the indoor light becomes weaker, the light emitted by the lamp beads will become brighter, and if the indoor light becomes stronger, the light emitted by the lamp beads will become weaker. The significance is to ensure that the indoor light intensity is close to the set value and will not fluctuate greatly. In this way, the indoor light can be kept at the set value in the evening, making the residents feel more warm and comfortable, which is more in line with the concept of smart home lighting. It should be noted that in the evening, as the sun sets and the sky darkens, the transition between light and shadow can trigger a sense of loneliness in people and cause a certain degree of visual discomfort. Therefore, it is necessary to make residents feel more warm and comfortable. Furthermore, optical fibers do not require energy consumption, and the lamp beads use electricity generated by photovoltaic panels as energy, thus achieving energy conservation. It should be emphasized that the present invention essentially constructs an integrated energy-saving lighting system that combines light introduced into the room through optical fibers with stepless adjustment of the light from lamp beads. When one light is enhanced, the other light will adaptively weaken. The two cooperate with each other to achieve coupled collaborative lighting, ensuring that the indoor lighting is always maintained within a comfortable range and does not flicker, especially in the evening / dawn, thereby improving the comfort of all-weather indoor lighting.

[0018] 2. Since the photovoltaic panel is set in the cover, it can prevent dust and ash and occupy a small area. In addition, the setting of the daily sensor can not only maximize the power generation efficiency of the photovoltaic panel, but also make the incident angle of the light of the convex lens close to zero, that is, the light is incident on the convex lens in parallel. The advantage is that, on the one hand, the optical fiber light guidance can be carried out smoothly, and on the other hand, the light focused by the convex lens can be irradiated into the cylinder shell and will not deviate to the photovoltaic panel. If it deviates to the photovoltaic panel, the focused light will easily cause damage to the photovoltaic panel, which plays a role in protecting the photovoltaic panel.

[0021] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0022] Reference Figures 1-8 An energy-saving smart home lighting assembly includes an external lighting unit 100 arranged outdoors and an internal lighting unit 200 arranged indoors (such as a living room or bedroom).

[0023] 1. External lighting unit 100: Reference Figure 2-Figure 4 The exterior lighting unit 100 includes a fixed base 101 provided on the exterior wall of the building, a rotating frame 102 is rotatably mounted on the fixed base 101, and a first connecting shaft formed at the rotating mounting position is perpendicular to the exterior wall of the building. Furthermore, the rotating frame 102 is driven to rotate by a first motor 103. Furthermore, the first motor 103 can be directly provided on the fixed base 101 and connected to the connecting shaft to form a power connection (not shown in the figure), or as shown in FIG. Figure 2 As shown, the motor housing of the first motor 103 is set on the rotating frame 102, and the output shaft is connected to the connecting shaft. In this way, when the first motor 103 is running, since the output shaft is restricted from rotating, the motor housing can rotate and rotate with the rotating frame 102. This is achievable with the existing technology and will not be elaborated on.

[0024] The cover 104 is rotatably mounted on the rotating frame 102 , and a second connecting shaft formed at the rotating mounting position is dynamically connected to a second motor 105 provided on the rotating frame 102 . The first connecting shaft and the second connecting shaft are perpendicular to each other.

[0025] The cover 104 is in the shape of a hollow cylindrical shell, and its axis is perpendicular to the second connecting axis.

[0026] One end of the cover 104 facing away from the outer wall of the building is configured to be transparent, for example, open and inlaid with glass.

[0027] An installation hole is provided at one end of the cover 104 facing away from the outer wall of the building, and a convex lens 107 is provided in the installation hole. A light guide 108 is provided in the cover 104, and the light guide 108 is used to receive the light focused by the convex lens 107 and guide the light to the optical fiber 300. Furthermore, there are multiple mounting hole arrays, and there are multiple convex lenses 107, so there are also multiple light guides 108, and there are multiple input ends of the optical fiber 300.

[0028] Specifically, the light guide 108 includes a cylindrical shell 1081, which is open at one end facing the external convex lens 107 and is provided with an internal convex lens 1082, and the other end of the cylindrical shell 1081 is closed. The input end of the optical fiber 300 extends into the cylindrical shell 1081, and a reflection ring 1083 is provided between the input end of the optical fiber 300 and the internal convex lens 1082. The reflection ring 1083 is trapezoidal and the outer diameter decreases from the open end to the closed end of the cylindrical shell 1081. The outer surface of the reflection ring 1083 is provided with a first reflection layer, and the outer periphery of the reflection ring 1083 is provided with a plurality of lamp beads 1084 in an array along its own circumferential direction.

[0029] In addition, a photovoltaic panel 109 and a battery 110 are also provided in the cover 104. The photovoltaic panel 109 is provided with an avoidance hole for avoiding the light guide 108. The electricity generated by the photovoltaic panel 109 is stored in the battery 110. This can be achieved with the existing photovoltaic power generation technology and will not be elaborated. The battery 110 supplies power to the lamp beads 1084.

[0030] In addition, a sun sensor 106 is provided on the cover 104, which is used to cooperate with the first motor 103 and the second motor 105 to keep the end of the cover 104 facing away from the outer wall of the building facing the sun. It should be noted that this technology is equivalent to the sun position sensor, horizontal rotation motor and pitch rotation motor in the patent literature mentioned in the background technology, which make the light collector always face the sun. It can be achieved with existing technology and will not be elaborated on.

[0031] 2. Internal lighting unit 200: Reference Figure 5-Figure 8 The interior lighting unit 200 includes a lampshade 201 disposed on the indoor ceiling. The lower end of the lampshade 201 is open and provided with a light diffusion plate 202 . A light guide switch 204 is provided in the lampshade 201 .

[0032] Specifically, the light guide switch 204 includes a threaded shaft 2041 arranged vertically and fixedly set in the lampshade 201. The threaded shaft 2041 is in the shape of a hollow shaft and the output end of the optical fiber 300 extends into the threaded shaft 2041. The light guided by the optical fiber 300 is irradiated vertically downward.

[0033] The external threaded sleeve of the threaded shaft 2041 is provided with a sleeve shaft 2042 in the shape of a hollow shaft. In addition, a third motor 2043 is provided in the lampshade 201. The third motor 2043 is used to drive the sleeve shaft 2042 to rotate. The sleeve shaft 2042 rotates and moves at the same time, thereby changing the position of the sleeve shaft 2042 on the threaded shaft 2041. Furthermore, a driven gear is provided on the outside of the sleeve shaft 2042, and a driving gear meshing with the driven gear is provided in the lampshade 201, and the axial length of the driving gear is much larger than the axial length of the driven gear. In the process of the sleeve shaft 2042 rotating and moving at the same time, the two remain meshed, and the third motor 2043 forms a power connection with the driving gear.

[0034] A connecting rod 2044 is provided at the bottom of the sleeve shaft 2042, and a reflecting cone 2045 is provided at the bottom of the connecting rod 2044. Furthermore, the reflecting cone 2045 is in the shape of a cone with an outer diameter that first increases and then decreases from bottom to top. The reflecting cone 2045 is coaxial with the threaded shaft 2041. When the sleeve shaft 2042 moves upward, the reflecting cone 2045 moves upward together with it. The reflecting cone 2045 can block the lower end of the threaded shaft 2041, so that the light guided by the optical fiber 300 is confined to the threaded shaft 2041 and cannot be irradiated into the room, that is, the light guidance of the optical fiber 300 is controlled on and off.

[0035] Furthermore, the outer surface of the reflective cone 2045 is provided with a second reflective layer, and the inner wall of the lampshade 201 is provided with a third reflective layer. When the light guide switch 204 is turned on, the light guided by the optical fiber 300 is irradiated on the reflective cone 2045. Through the cooperation of the second reflective layer and the third reflective layer, the light can be guided to pass through the diffuser 202 and irradiate into the room. The diffuser 202 has the effect of uniformly scattering the light, so the light is evenly irradiated into the room.

[0036] Furthermore, a lamp 203 is provided in the lampshade 201 , and the lamp 203 is connected to a household circuit, that is, the household circuit supplies power to the lamp 203 .

[0037] Furthermore, a light sensor for detecting light intensity is also provided indoors, for example, an illumination sensor or an ambient light sensor is used, which is achievable with existing technologies and will not be described in detail.

[0038] How this solution works: When the light guide switch 204 is turned on, light from outside the building is guided into the lampshade 201 by the convex lens 107, the light guide 108, the optical fiber 300, and the light guide switch 204. With the cooperation of the second reflective layer, the third reflective layer, and the diffuser 202, the light is evenly irradiated into the room. On the contrary, when the light guide switch 204 is turned off, the light from outside the building cannot irradiate into the room. Therefore, during the day, the light intensity in the room is monitored in real time by the light sensor. If the light intensity in the room is greater than or equal to the set value, the light guide switch 204 is turned off, otherwise it is turned on to keep the room bright. In addition, the electricity generated by the photovoltaic panel 109 is stored in the battery 110. In the evening, as the light outside the building gradually weakens, the light introduced into the room through the optical fiber 300 gradually weakens. At this time, the light guide switch 204 is turned on, and the light intensity in the room is monitored in real time through the light sensor. If it is lower than the set value, the lamp bead 1084 is started, and the light emitted by the lamp bead 1084 is irradiated to the input end of the optical fiber 300 through the first reflective layer, providing more light for the room. It should be noted that the lamp bead 1084 adopts a stepless brightness adjustment technology, that is, the lamp bead 1084 can adjust the light it emits according to the light intensity in the room. For example, if the indoor light becomes weaker, the light emitted by the lamp bead 1084 will be stronger, and if the indoor light becomes stronger, the light emitted by the lamp bead 1084 will be weaker. The significance is to ensure that the indoor light intensity is near the set value and will not fluctuate greatly. In this way, the indoor light can be kept at the set value in the evening, making the residents feel warmer and more comfortable, which is more in line with the concept of smart home lighting.

[0039] It should be noted that in the evening, as the sun sets and the sky darkens, the transition of light and shadow will trigger a sense of loneliness in people. Therefore, it is necessary to make the residents feel warmer and more comfortable.

[0040] In addition, since the photovoltaic panel 109 is arranged in the cover 104, it can be dust-proof and occupies a small area. In addition, the setting of the daily sensor 106, in addition to maximizing the power generation efficiency of the photovoltaic panel 109, can also make the incident angle of the light of the convex lens 107 close to zero, that is, the light is incident on the convex lens 107 in parallel. The advantage is that, on the one hand, the optical fiber 300 can guide the light smoothly, and on the other hand, the light focused by the convex lens 107 can be irradiated into the cylindrical shell 1081 and will not deviate to the photovoltaic panel 109. If it deviates to the photovoltaic panel 109, the focused light will easily cause damage to the photovoltaic panel 109, which plays a role in protecting the photovoltaic panel 109.

[0041] It should be noted that the circuit control between the above-mentioned sensor technology, controller, lamp beads 1084, etc. can be realized by existing technology and will not be elaborated on.

[0042] In addition, the lamp 203 is provided for lighting at night.

[0043] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
