Description

Technical Field

[0001] This invention relates to the field of lighting, specifically to the field of household lighting, and particularly to an energy-saving smart home lighting component. Background Technology

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

[0003] Based on a search for energy-saving lighting fixtures, a Chinese utility model patent was found, with authorization announcement number CN217684737U, which discloses a self-powered fiber optic sunlight-guiding lighting system. This system uses a combination of a solar position sensor and a sunlight intensity sensor to ensure the light-collecting device always faces the sun, guiding sunlight into the room. Solar panels then generate photovoltaic power and store the energy, achieving 100% clean energy usage and thus energy saving. However, it still has some shortcomings: 1. The solar panels are simply mounted on top of the controller, resulting in a large footprint and low power generation efficiency; 2. People seek warmth and comfort in their lives. In lighting, this translates to maintaining a certain level of indoor illumination during periods of transition, such as in the evening, to ensure a smooth transition between light and dark. Conversely, if the indoor brightness dims along with the external environment during these transition periods, it can cause psychological and emotional discomfort for the occupants. While this patent achieves energy saving, it cannot maintain the set brightness during these transitions.

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

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

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows.

[0007] An energy-saving smart home lighting component includes an outdoor light-collecting unit installed outdoors, an indoor lighting unit installed indoors, and an optical fiber installed between the two. The outdoor light-collecting unit includes a housing, the end of the housing facing away from the building's exterior wall being transparent, a mounting hole being provided at the end of the housing facing away from the building's exterior wall, an external convex lens being provided in the mounting hole, and a light guide being provided inside the housing.

[0008] The light guide includes a cylindrical shell, which is open at one end facing the external convex lens and is provided with an internal convex lens. The input end of the optical fiber extends into the cylindrical shell. A reflective ring is provided between the input end of the optical fiber and the internal convex lens. The reflective ring is frustum-shaped and its outer diameter decreases from the open end of the cylindrical shell to the closed end. A first reflective layer is provided on the outer surface of the reflective ring. Several LED beads are arranged in an array around the periphery of the reflective ring along its own circumference.

[0009] The external lighting unit also includes photovoltaic panels and batteries. The electricity generated by the photovoltaic panels is stored in the batteries, which in turn power the LED chips.

[0010] As a further improvement and optimization of the present invention, the external lighting unit includes a fixed seat set on the exterior wall of the building, a rotating frame rotatably mounted on the fixed seat and a first connecting shaft formed at the rotatable mounting point perpendicular to the exterior wall of the building, a cover rotatably mounted on the rotating frame and a second connecting shaft formed at the rotatable mounting point perpendicular to the first connecting shaft, and the cover is a cylindrical shell shape with its axis perpendicular to the second connecting shaft.

[0011] As a further improvement and optimization of the present invention, the photovoltaic panel is disposed inside the housing and the photovoltaic panel is provided with a clearance hole for avoiding the light guide component.

[0012] As a further improvement and optimization of the present invention, the external light-collecting unit also includes a first motor for driving the rotating frame to rotate and a second motor for driving the housing to rotate.

[0013] As a further improvement and optimization of the present invention, a daily sensor is provided on the cover. The daily sensor, together with the first motor and the second motor, enables the end of the cover that is away from the building's exterior wall to keep facing the sun.

[0014] As a further improvement and optimization of the present invention, the interior lighting unit includes a lampshade installed on the interior ceiling, the lower end of the lampshade being open and equipped with a diffuser plate, and a light guide switch being installed inside the lampshade.

[0015] As a further improvement and optimization of the present invention, the light guide switch includes a threaded shaft arranged vertically and fixedly installed inside the lampshade. The threaded shaft is hollow and the output end of the optical fiber extends into the threaded shaft, so that the light guided by the optical fiber shines vertically downward.

[0016] The threaded shaft is fitted with a hollow shaft sleeve on its outer thread, and a third motor is installed inside the lampshade to drive the sleeve to rotate.

[0017] 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 a cone shape with an outer diameter that increases first and then decreases from bottom to top. The reflective cone is coaxial with the threaded shaft. When the sleeve shaft moves upward, it moves upward with the reflective cone. The reflective cone can seal the lower end of the threaded shaft.

[0018] 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 is provided inside the lamp cover to mesh with the driven gear, and the shaft length of the driving gear is greater than the shaft length of the driven gear. During 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.

[0019] As a further improvement and optimization of the present invention, a second reflective layer is provided on the outer surface of the reflective cone, a third reflective layer is provided on the inner wall of the lampshade, and a lamp is also provided inside the lampshade, which is connected to the household circuit.

[0020] As a further improvement and optimization of the present invention, a light sensor for detecting light intensity is installed indoors;

[0021] As dusk falls and the light outside the building gradually dims, the light entering the building through the optical fiber also gradually weakens. At this time, the light guide switch is turned on, and the light intensity inside the building is monitored in real time by the light sensor. If the indoor light intensity is lower than the set value, the LED beads are activated. The light emitted by the LED beads passes through the first reflective layer and shines on the input end of the optical fiber, and finally shines into the room through the optical fiber, providing more light to the room. The brightness of the LED beads can be steplessly adjusted. Therefore, as time goes by, the brightness emitted by the LED beads continuously increases, thereby keeping the indoor brightness at the set value.

[0022] Compared with the prior art, the beneficial effects of this invention are as follows:

[0023] 1. This solution, through the integrated structure of LED chips and optical fibers, can achieve the following functions:

[0024] As evening approaches and the external light gradually dims, the light entering the building through fiber optic cables also weakens. At this time, the light guide switch automatically turns on, and the light sensor monitors the indoor light intensity in real time. If it falls below the set value, the LEDs activate, emitting light that passes through the first reflective layer to illuminate the input end of the fiber optic cable, providing more and stronger light into the room. It's important to note that the LEDs employ stepless brightness adjustment technology, meaning they can adjust their emitted light according to the indoor light intensity. For example, if the indoor light dims, the LEDs emit brighter light, and vice versa. This ensures that the indoor light intensity remains near the set value without significant fluctuations, maintaining the set level of indoor brightness in the evening, creating a more warm and comfortable atmosphere for residents, aligning with the concept of smart home lighting. However, it's also important to note that as the sun sets and the sky darkens in the evening, the changing light and shadow can trigger feelings of loneliness and visual discomfort. Therefore, creating a warm and comfortable environment for residents is essential.

[0025] Furthermore, optical fibers require no energy consumption, and the LED chips use electricity generated by the photovoltaic panel as their energy source, thus achieving energy-saving goals.

[0026] It should be emphasized that the present invention essentially constructs an integrated energy-saving lighting system that combines the light introduced into the room through optical fiber with the stepless adjustment of the light from the LED beads. When one light is enhanced, the other light will be adaptively weakened. The two work together to achieve coupled and coordinated lighting, ensuring that the indoor lighting is always maintained within a comfortable range and does not fluctuate in brightness. Especially at dusk / dawn, it improves the comfort of indoor lighting throughout the day.

[0027] 2. Since the photovoltaic panel is installed inside the casing, it can effectively prevent dust and ash accumulation and has a small footprint. In addition, the daily sensor not only maximizes the power generation efficiency of the photovoltaic panel, but also ensures that the incident angle of light from the convex lens is close to zero, that is, the light is incident parallel to the convex lens. This has the advantage of ensuring that the optical fiber can guide light smoothly and that the light focused by the convex lens can illuminate the inside of the casing without deviating from the photovoltaic panel. If the light deviates from the photovoltaic panel, the focused light can easily damage the photovoltaic panel, thus protecting the photovoltaic panel. Attached Figure Description

Detailed Implementation

[0038] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0039] Reference Figures 1-8 An energy-saving smart home lighting component includes an outdoor lighting unit 100 installed outdoors and an indoor lighting unit 200 installed indoors (e.g., in a living room or bedroom).

[0040] I. External lighting unit 100:

[0041] Reference Figures 2-4 The external lighting unit 100 includes a fixed base 101 mounted 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 rotatable mounting point is perpendicular to the exterior wall of the building. Furthermore, the rotating frame 102 is driven to rotate by a first motor 103. Even further, the first motor 103 can be directly mounted on the fixed base 101 and connected to the connecting shaft in a power connection (not shown in the figure), or as... Figure 2 As shown, the motor housing of the first motor 103 is mounted 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, the output shaft is restricted from rotating, so the motor housing can rotate and rotate together with the rotating frame 102. This is achievable with existing technology and will not be described in detail.

[0042] A cover 104 is rotatably mounted on the rotating frame 102, and a second connecting shaft formed at the rotatable mounting point is connected to a second motor 105 mounted on the rotating frame 102. The first connecting shaft and the second connecting shaft are perpendicular to each other.

[0043] The cover 104 is a hollow cylindrical shell with its axis perpendicular to the second connecting shaft.

[0044] The end of the enclosure 104 facing away from the building's exterior wall is made transparent, for example, open and fitted with glass.

[0045] The end of the housing 104 facing away from the building's exterior wall has a mounting hole. A convex lens 107 is installed inside the mounting hole. A light guide 108 is installed inside the housing 104. 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, multiple convex lenses 107, multiple light guides 108, and multiple input ends of the optical fiber 300.

[0046] Specifically, the light guide 108 includes a cylindrical shell 1081. One end of the cylindrical shell 1081 facing the external convex lens 107 is open and an internal convex lens 1082 is provided. The other end of the cylindrical shell 1081 is closed. The input end of the optical fiber 300 extends into the cylindrical shell 1081. A reflective ring 1083 is provided between the input end of the optical fiber 300 and the internal convex lens 1082. The reflective ring 1083 is frustum-shaped and its outer diameter decreases from the open end to the closed end of the cylindrical shell 1081. A first reflective layer is provided on the outer surface of the reflective ring 1083. A plurality of LED beads 1084 are arranged in an array around the periphery of the reflective ring 1083 along its own circumferential direction.

[0047] In addition, a photovoltaic panel 109 and a battery 110 are also provided inside the housing 104. The photovoltaic panel 109 is provided with a clearance hole for avoiding the light guide 108. The electricity generated by the photovoltaic panel 109 is stored in the battery 110. This is achievable with existing photovoltaic power generation technology and will not be described in detail. The battery 110 supplies power to the lamp beads 1084.

[0048] In addition, a daily sensor 106 is provided on the housing 104 to work with the first motor 103 and the second motor 105 to keep the end of the housing 104 away from the building's outer wall facing the sun. It should be noted that this technology is equivalent to the combination of a solar position sensor, a horizontal rotating motor and a pitch rotating motor in the patent documents mentioned in the background art to keep the light collector always facing the sun. This is achievable with existing technology and will not be elaborated further.

[0049] II. Internal lighting unit 200:

[0050] Reference Figures 5-8 The interior lighting unit 200 includes a lampshade 201 installed on the interior ceiling. The lower end of the lampshade 201 is open and has a diffuser 202. A light guide switch 204 is installed inside the lampshade 201.

[0051] Specifically, the light guide switch 204 includes a threaded shaft 2041 arranged vertically and fixedly installed inside the lamp cover 201. The threaded shaft 2041 is hollow and the output end of the optical fiber 300 extends into the threaded shaft 2041. The light guided by the optical fiber 300 shines vertically downward.

[0052] The threaded shaft 2041 is externally threaded with a hollow shaft sleeve 2042. In addition, a third motor 2043 is installed inside the lamp cover 201. The third motor 2043 is used to drive the sleeve 2042 to rotate. The sleeve 2042 rotates and moves at the same time, thereby changing the position of the sleeve 2042 on the threaded shaft 2041. Furthermore, a driven gear is provided on the outside of the sleeve 2042, and a driving gear is provided inside the lamp cover 201 to mesh with the driven gear. The shaft length of the driving gear is much larger than the shaft length of the driven gear. During the process of the sleeve 2042 rotating and moving, the two remain meshed. The third motor 2043 and the driving gear form a power connection.

[0053] A connecting rod 2044 is provided at the bottom of the sleeve shaft 2042, and a reflective cone 2045 is provided at the bottom of the connecting rod 2044. Furthermore, the reflective cone 2045 is a cone shape with an outer diameter that increases from bottom to top and then decreases. The reflective cone 2045 is coaxial with the threaded shaft 2041. When the sleeve shaft 2042 moves upward, it moves upward along with the reflective cone 2045. The reflective cone 2045 can block the lower end of the threaded shaft 2041, thereby restricting the light guided by the optical fiber 300 to be confined within the threaded shaft 2041 and preventing it from shining into the room. This enables on / off control of the optical fiber 300's light guiding.

[0054] Furthermore, a second reflective layer is provided on the outer surface of the reflective cone 2045, and a third reflective layer is provided on the inner wall of the lampshade 201. When the light guide switch 204 is turned on, the light guided by the optical fiber 300 shines on the reflective cone 2045. Through the cooperation of the second and third reflective layers, the light can be guided through the diffuser 202 and shine into the room. The diffuser 202 has the effect of uniformly scattering the light, so the light shines into the room evenly.

[0055] Furthermore, a lamp 203 is installed inside the lamp shade 201. The lamp 203 is connected to the household circuit, meaning that the household circuit supplies power to the lamp 203.

[0056] Furthermore, the room is also equipped with a light sensor for detecting light intensity, such as an illuminance sensor or an ambient light sensor, which is feasible with existing technology and will not be elaborated upon.

[0057] How this solution works:

[0058] 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 shines evenly into the room. Conversely, when the light guide switch 204 is turned off, light from outside the building cannot shine into the room.

[0059] Therefore, during the daytime, the light intensity of the room is monitored in real time by a light sensor. If the indoor light intensity is greater than or equal to the set value, the light guide switch 204 is turned off, and 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.

[0060] As evening approaches and the external light gradually dims, the light entering the building through fiber optic cable 300 also weakens. At this time, light guide switch 204 turns on, and the light sensor monitors the indoor light intensity in real time. If it falls below the set value, LED 1084 is activated. The light emitted by LED 1084 passes through the first reflective layer and illuminates the input end of fiber optic cable 300, providing more light into the room. It is important to note that LED 1084 uses stepless brightness adjustment technology, meaning that LED 1084 can adjust its emitted light according to the indoor light intensity. For example, if the indoor light dims, LED 1084 emits brighter light, and if the indoor light brightens, LED 1084 emits weaker light. The purpose is to ensure that the indoor light intensity remains near the set value without significant fluctuations. In this way, the indoor light level is maintained 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.

[0061] It is important to note that as evening approaches, the setting sun and darkening sky can trigger a sense of loneliness due to the changing light and shadow. Therefore, it is essential to make residents feel warmer and more comfortable.

[0062] In addition, since the photovoltaic panel 109 is located inside the housing 104, it can prevent dust and ash and has a small footprint. Furthermore, the daily sensor 106 not only maximizes the power generation efficiency of the photovoltaic panel 109, but also makes the incident angle of the light from the convex lens 107 close to zero, that is, the light is incident parallel to the convex lens 107. The advantage is that, on the one hand, the light guiding of the optical fiber 300 can be smooth and stable, and on the other hand, the light focused by the convex lens 107 can illuminate the inside of the housing 1081 and will not deviate from the photovoltaic panel 109. If it deviates from the photovoltaic panel 109, the focused light will easily damage the photovoltaic panel 109, thus protecting the photovoltaic panel 109.

[0063] It should be noted that the circuit control between the aforementioned sensor technology, controller, and LED 1084 is achievable with existing technology and will not be elaborated upon.

[0064] In addition, the lamp 203 is installed for nighttime illumination.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
