Description

Technical Field

[0001] This invention relates to the technical field of lighting systems, and in particular to an energy-saving ceiling landscape lighting system. Background Technology

[0002] Modern ceilings are equipped with lighting systems to provide illumination and enhance the visual effect of the scenery below. Various ceiling lighting devices are disclosed in the prior art. For example, Chinese invention application CN118640438A discloses a large-area exhibition hall ceiling lighting device. This device includes a ceiling frame with a lifting motor mounted on it. The lifting motor is connected to a light panel via cables. A first LED light group is mounted on the bottom surface of the light panel. A ring-shaped slot is located at the center of the top surface of the light panel, and a filter tube is inserted into the slot. A second LED light group is installed inside the filter tube. Several reflectors are mounted on the top of the filter tube to facilitate fine adjustment of the illuminance within the exhibition hall.

[0003] However, the first and second LED light groups of the aforementioned ceiling lighting device are both directly installed on the ceiling, resulting in a large overall size and weight of the lighting device installed on the ceiling. The excessive size and weight increase the risk of falling. Since the lifespan of LED light groups is limited, the high installation height makes it difficult to repair and replace the ceiling lighting device when the LED light groups are damaged. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a ceiling landscape energy-saving lighting system that utilizes fiber optic light guiding, separating the light source and illumination components, reducing the risk of falls, facilitating maintenance and replacement, and improving reliability.

[0005] This invention discloses an energy-saving ceiling landscape lighting system, comprising a control box, an optical cable, and a light box; it also includes a lower light-emitting panel, a light guide column, a light-receiving sphere, and an upper light-emitting panel. A light source unit is installed inside the control box, and the light source unit emits light. The input end of the optical cable is connected to the output end of the light source unit. The light box is installed below the ceiling, and an installation chamber is provided inside the light box. A light outlet communicating with the installation chamber is provided on the lower end face of the light box. The lower light-emitting panel is installed on the light outlet. The lower end of the light guide column is connected to the lower light-emitting panel, and a light-receiving sphere is provided on the upper end of the light guide column, extending above the ceiling. The upper light-emitting panel is installed in the middle of the installation chamber of the light box, located above the lower light-emitting panel. The output end of the optical cable is connected to the upper light-emitting panel. The control box is installed in a control room at ground level or a lower location. The optical cable can be made of plastic optical fiber to reduce weight and cost. The outer wall of the optical cable is wrapped with a light-blocking layer. The lower light-emitting panel... The lower surface is arc-shaped, giving the lower light-emitting panel a lens effect. During the day, when there is ample sunlight, sunlight shines on the light-inlet sphere and is conducted through the light guide column to the lower light-emitting panel, which then emits light downwards from the ceiling, supplementing the lighting below. At this time, the light source unit inside the control box is turned off, achieving energy saving. When there is insufficient sunlight, the light source unit inside the control box turns on, emitting light. The emitted light is conducted through an optical cable to the upper light-emitting panel and emitted outwards. The light emitted from the upper light-emitting panel is focused by the lens effect of the lower light-emitting panel and emitted downwards from the ceiling for illumination. Compared to existing technologies, the light source assembly is no longer directly installed on the ceiling but is instead centrally installed at a lower position, reducing the overall size and weight of the lighting device installed on the ceiling, lowering the risk of falling. In case of damage, the lower and centrally installed light source assembly makes maintenance and replacement easier and improves reliability.

[0006] Preferably, it also includes a reflector, which is installed on the top of the mounting chamber of the light box and is located above the upper light-emitting panel; the reflector reflects the light emitted by the lower light-emitting panel and the upper light-emitting panel downwards to improve the lighting effect.

[0007] Preferably, it also includes an outer casing and a condensing lens. The outer casing has a light-receiving chamber inside, and the light-incoming sphere is located in the middle of the light-receiving chamber. The condensing lens is installed on the top of the light-incoming sphere. The position of the light-incoming sphere is adjusted so that it is within the focal range of the condensing lens, so that the condensing lens concentrates a large area of ​​sunlight onto the light-incoming sphere, increasing the amount of sunlight entering, thereby improving the lighting effect of the lower light-emitting panel.

[0008] Preferably, the light-receiving chamber of the outer casing is filled with transparent fluorescent liquid; the fluorescent liquid absorbs ultraviolet light to store energy and excite, which can reduce the intensity of ultraviolet light below the ceiling. At night, the fluorescent liquid emits light, and the fluorescence is conducted to the lower light-emitting plate through the light-inlet sphere and light guide column, so that the lower light-emitting plate emits fluorescence to illuminate the area below the ceiling. This is suitable for low-light usage scenarios such as when there is no one under the ceiling, and further saves energy and reduces consumption.

[0009] Preferably, it also includes an expansion vessel, which is installed on the outside of the outer casing. The expansion vessel is higher than the condenser lens, and the bottom of the expansion vessel is connected to the light-receiving chamber of the outer casing. When the light-receiving chamber of the outer casing is filled with fluorescent liquid, the level of the fluorescent liquid in the expansion vessel is higher than the condenser lens. Thus, when the fluorescent liquid in the outer casing contracts at low temperatures, the fluorescent liquid in the expansion vessel replenishes the outer casing. When the fluorescent liquid in the outer casing expands at high temperatures, the fluorescent liquid in the outer casing enters the expansion vessel for buffering, thereby improving reliability.

[0010] Preferably, the light source unit includes a light-emitting unit, a controller, and a receiving unit. All three units are installed inside a control box. The output of the light-emitting unit is connected to the input of the optical cable. The controller controls the operation of the light-emitting unit, and the receiving unit is installed on the controller to input the control program for the light-emitting unit. Multiple light-emitting units can be set up, connected by multiple optical cables, and multiple light boxes are set up, arranged in different positions on the ceiling to achieve distributed overall lighting below the ceiling. The receiving unit is connected to the upper-level control system via a communication module. Operators can remotely send control programs to the receiving unit. The controller executes the control programs to control the multiple light-emitting units, turning designated units on or off. The light emitted by the light-emitting units is output through the optical cable, causing the upper light-emitting panel in the designated light box to emit light, achieving different lighting effects.

[0011] Preferably, the light-emitting unit includes a lamp control board, multiple lamp groups, a lamp housing, a beam splitter, multiple beam splitting columns, and optical connectors. The upper light-emitting board is composed of multiple small light-emitting panels arranged in a matrix. Multiple optical fibers are internally arranged in the optical cable, and the output ends of these fibers are respectively connected to the multiple small light-emitting panels on the upper light-emitting board. The lamp control board is electrically connected to a controller. Multiple lamp groups are matrix-mounted on the lamp control board. Multiple mounting grids are provided on the lamp housing, and the multiple lamp groups are located at the rear ends of the mounting grids on the lamp housing. Multiple optical path channels are internally arranged in the beam splitter. Optical connectors communicating with the multiple optical path channels are provided on the back of the beam splitter. The optical connectors are respectively connected to the input ends of the multiple optical fibers in the optical cable. Multiple beam splitting columns are mounted on the beam splitter, and each beam splitting column is connected to multiple optical paths on the beam splitter. The light extends into the front of multiple mounting grids in the lampshade. After receiving the control signal from the controller, the lamp control board controls multiple designated lamp groups to turn on or off. When multiple lamp groups are turned on, they emit light. The multiple mounting grids in the lampshade will focus and separate the light emitted by the multiple lamp groups, so that the light emitted by the multiple lamp groups passes through the corresponding optical paths of the multiple beam splitters and beam splitters and optical connectors into the optical fibers of the optical cable. The light then enters the multiple small light-emitting panels on the upper light-emitting panel along the corresponding optical fibers, causing the designated small light-emitting panels to emit light and achieve different lighting effects. The multiple small light-emitting panels on the upper light-emitting panel can be made to emit light in a regular manner to display text and pictures, etc., to achieve advertising effects, or to form different shapes with the multiple small light-emitting panels of the scenery under the ceiling to enhance the landscape effect.

[0012] Preferably, it also includes multiple small lenses, which are respectively installed in multiple mounting grids of the lamp cover body, and the multiple lamp covers body are respectively located between multiple beam splitters and multiple lamp groups; the multiple small lenses respectively focus the light emitted by the multiple lamp groups towards the multiple beam splitters to improve the lighting effect.

[0013] Preferably, the light group is a multi-color LED light group; by adjusting the light emission color of multiple light groups, multiple small light-emitting panels on the upper light-emitting panel emit light of different colors, thereby forming colorful patterns and text, and improving the advertising and landscape effects.

[0014] Preferably, it also includes a cooler, which is installed in the control box; the cooler cools and dissipates heat from the light-emitting unit and the controller in the control box, thereby improving the reliability of the light-emitting unit and the controller.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the light source assembly is no longer directly installed on the ceiling, but is centrally installed at a lower position, which reduces the overall volume and weight of the lighting device installed on the ceiling, reduces the risk of falling, and makes maintenance and replacement easier and improves reliability when the light source assembly is damaged.

[0027] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0028] Example 1, such as Figures 1 to 6 As shown, a ceiling landscape energy-saving lighting system includes a control box 1, an optical cable 2, and a light box 3; it also includes a lower light-emitting panel 4, a light guide column 5, a light-inlet sphere 6, and an upper light-emitting panel 7. A light source unit is installed inside the control box 1, which emits light. The input end of the optical cable 2 is connected to the output end of the light source unit. The light box 3 is installed below the ceiling, and an installation chamber is provided inside the light box 3. A light outlet communicating with the installation chamber is provided on the lower end face of the light box 3. The lower light-emitting panel 4 is installed on the light outlet. The lower end of the light guide column 5 is connected to the lower light-emitting panel 4, and the upper end of the light guide column 5 is provided with the light-inlet sphere 6, which extends above the ceiling. The upper light-emitting panel 7 is installed in the middle of the installation chamber of the light box 3, and is located above the lower light-emitting panel 4. The output end of the optical cable 2 is connected to the upper light-emitting panel 7. It also includes a reflector 8, which is installed on the top of the installation chamber of the light box 3, and is located above the upper light-emitting panel 7.

[0029] The control box 1 is installed in a control room on the ground or at a lower location. The optical cable 2 can be made of plastic optical fiber to reduce weight and cost. The outer wall of the optical cable 2 is wrapped with a light-blocking layer. The lower surface of the lower light-emitting plate 4 is arc-shaped, giving it a lens effect. The reflector 8 reflects the light emitted by the lower light-emitting plate 4 and the upper light-emitting plate 7 downwards, improving the lighting effect. During the day when there is sufficient sunlight, sunlight shines on the light-inlet sphere 6 and is conducted through the light guide column 5 to the lower light-emitting plate 4, which then emits light downwards through the lower light-emitting plate 4 to supplement the lighting below the ceiling. At this time, the light source unit inside the control box 1 is turned off. This achieves energy conservation. When there is insufficient sunlight, the light source unit inside the control box 1 is turned on, and the light source unit emits light. The emitted light is transmitted through the optical cable 2 to the upper light-emitting plate 7 and emitted outward. The light emitted by the upper light-emitting plate 7 is focused by the lens effect of the lower light-emitting plate 4 and emitted downward to the ceiling for illumination. Compared with the existing technology, the light source group is no longer directly installed on the ceiling, but is concentrated in a lower position, which reduces the overall volume and weight of the lighting device installed on the ceiling and reduces the risk of falling. When the light source group is damaged, the lower and concentrated installation of the light source group makes maintenance and replacement easier.

[0030] Example 2, as Figures 1 to 7 As shown, based on Embodiment 1, it also includes an outer housing 9 and a condensing lens 10. The outer housing 9 has a light-receiving chamber inside, and a light-entering sphere 6 is located in the middle of the light-receiving chamber of the outer housing 9. The condensing lens 10 is installed on the top of the light-entering sphere 6. The light-receiving chamber of the outer housing 9 is filled with transparent fluorescent liquid. It also includes an expansion vessel 11, which is installed on the outside of the outer housing 9. The expansion vessel 11 is higher than the condensing lens 10, and the bottom of the expansion vessel 11 is connected to the light-receiving chamber of the outer housing 9.

[0031] When the fluorescent liquid fills the light-receiving chamber of the outer casing 9, the level of the fluorescent liquid in the expansion vessel 11 is higher than that of the condensing lens 10. Therefore, at low temperatures, when the fluorescent liquid in the outer casing 9 contracts, the fluorescent liquid in the expansion vessel 11 replenishes the outer casing 9. At high temperatures, the fluorescent liquid in the outer casing 9 expands, causing it to enter the expansion vessel 11 for buffering. This adjusts the position of the light-receiving sphere 6, placing it within the focal range of the condensing lens 10. This allows the condensing lens 10 to concentrate sunlight onto the light-receiving sphere 6, increasing the amount of sunlight entering and thus improving the illumination effect of the lower light-emitting plate 4. The fluorescent liquid absorbs ultraviolet light for energy storage and excitation, reducing the intensity of ultraviolet radiation below the ceiling. At night, the fluorescent liquid emits light, which is conducted through the light-receiving sphere 6 and the light guide column 5 to the lower light-emitting plate 4, causing the lower light-emitting plate 4 to emit fluorescence to illuminate the area below the ceiling. This is suitable for low-light applications where there are no people below the ceiling, further saving energy and reducing consumption.

[0032] Example 3, as Figure 1 , Figure 2 , Figures 8 to 10 As shown, based on Embodiment 1, the light source unit includes a light-emitting unit 12, a controller 13, and a receiving unit 14. The light-emitting unit 12, controller 13, and receiving unit 14 are all installed inside the control box 1. The output end of the light-emitting unit 12 is connected to the input end of the optical cable 2 via optical path. The controller 13 is used to control the operation of the light-emitting unit 12. The receiving unit 14 is installed on the controller 13 and is used to input the control program of the light-emitting unit 12. The light-emitting unit 12 includes a lamp group control board 15, multiple lamp groups 16, a lamp shade 17, a beam splitter 18, multiple beam splitters 19, and an optical connector 20. The upper light-emitting plate 7 is composed of multiple small light-emitting plates arranged in a matrix. Multiple optical fibers are installed inside the optical cable 2, and the output ends of the multiple optical fibers are connected to the multiple small light-emitting plates of the upper light-emitting plate 7. The lamp group control board 15 is electrically connected to the controller 13. The lamp group control board 15 is rectangularly arranged in a matrix. The system includes multiple lamp groups 16, with multiple mounting grids on the lamp cover 17. Each lamp group 16 is located at the rear end of one of the mounting grids on the lamp cover 17. A beam splitter 18 has multiple optical path channels inside, and an optical connector 20 connected to these channels is located on the back of the beam splitter 18. The optical connector 20 is connected to the input ends of multiple optical fibers in the optical cable 2. Multiple beam splitting columns 19 are mounted on the beam splitter 18, each connected to one of the optical paths on the beam splitter 18. The beam splitting columns 19 extend into the front ends of the mounting grids on the lamp cover 17. The system also includes multiple small lenses 21, each installed in one of the mounting grids on the lamp cover 17. The lamp covers 17 are located between the beam splitting columns 19 and the lamp groups 16. The lamp groups 16 are multi-color LED lamp groups. Finally, a cooler 22 is installed in the control box 1.

[0033] Cooler 22 cools and dissipates heat from the light-emitting unit 12 and controller 13 in control box 1, improving their reliability. Multiple light-emitting units 12 can be set up, and they are connected by multiple optical cables 2. Multiple light boxes 3 are also set up and arranged in different positions on the ceiling to achieve distributed overall lighting below the ceiling. Receiver 14 is connected to the upper-level control system through a communication module. Staff can remotely send control programs to receiver 14. Controller 13 executes the control programs to control multiple light-emitting units 12, turning designated units 12 on or off. The light emitted by the light-emitting units 12 is output through optical cables 2, causing the upper light-emitting panel 7 in the designated light box 3 to emit light, achieving different lighting effects.

[0034] After receiving the control signal from the controller 13, the further lamp control board 15 controls the multiple designated lamp groups 16 to turn on or off. When the multiple lamp groups 16 are turned on, they emit light. The multiple mounting grids and multiple small lenses 21 of the lamp cover 17 will respectively focus and separate the light emitted by the multiple lamp groups 16, so that the light emitted by the multiple lamp groups 16 passes through the corresponding optical paths of the corresponding multiple beam splitters 19 and beam splitters 18 and the optical connectors 20 and is input into the optical fiber of the optical cable 2. The light is then input along the corresponding optical fiber to the multiple small light-emitting panels designated on the upper light-emitting panel 7, so that the designated small light-emitting panels emit light, achieving different lighting effects. The multiple small light-emitting panels on the upper light-emitting panel 7 can emit light in a regular manner, displaying text and pictures, etc., to achieve advertising effects, or they can be combined with the multiple small light-emitting panels under the ceiling to form different shapes, improving the landscape effect. By adjusting the light emission color of the multiple lamp groups 16, the multiple small light-emitting panels on the upper light-emitting panel 7 emit different colors of light, thereby forming colored patterns and text, further improving the advertising and landscape effects.

[0035] like Figures 1 to 10As shown, this invention provides an energy-saving ceiling landscape lighting system. During operation, the control box 1 is installed on the ground or in a control room at a lower location. During the day, when there is sufficient sunlight, sunlight shines through the focusing lens 10 onto the light-injecting sphere 6 and is conducted through the light guide column 5 to the lower light-emitting plate 4. The lower light-emitting plate 4 then emits light downwards from the ceiling, supplementing the lighting below. At this time, the light source unit inside the control box 1 is turned off, achieving energy saving. Simultaneously, the fluorescent liquid absorbs ultraviolet light for energy storage and excitation, reducing the intensity of ultraviolet light below the ceiling. Then, at night, the fluorescent liquid emits light, and the fluorescence is transmitted through the light-injecting sphere 6 and the light guide column 5. The light is directed to the lower light-emitting panel 4, which emits fluorescence to illuminate the area below the ceiling. This is suitable for low-lighting scenarios where there is no one under the ceiling. When there is insufficient sunlight, staff can remotely send a control program to the receiving unit 14. The controller 13 executes the control program to control multiple light-emitting units 12, turning the designated units on or off. Finally, the light emitted by the light-emitting units 12 is output through the optical cable 2, causing the upper light-emitting panel 7 in the designated light box 3 to emit light. The light emitted by the upper light-emitting panel 7 passes through the lower light-emitting panel 4 and is emitted to the area below the ceiling for illumination.

[0036] The main functions achieved by this invention are:

[0037] 1. The light source assembly is no longer directly installed on the ceiling, but is centrally installed at a lower position, which reduces the overall size and weight of the lighting device installed on the ceiling and reduces the risk of falling;

[0038] 2. When the light source assembly is damaged, the lower and more centralized installation of the light source assembly makes maintenance and replacement easier and improves reliability;

[0039] 3. The fluorescent liquid absorbs ultraviolet light to store energy and excite it, which can reduce the intensity of ultraviolet light below the ceiling. At night, the fluorescent liquid emits light, causing the lower light-emitting plate 4 to emit fluorescence to illuminate the area below the ceiling, which is more energy-efficient and reduces consumption.

[0040] 4. By controlling the light emission of different upper light-emitting panels 7, text and images can be displayed to achieve advertising effects, or multiple small light-emitting panels can be combined with the scenery below the canopy to form different shapes and improve the landscape effect.

[0041] The ceiling landscape energy-saving lighting system of the present invention uses common mechanical methods for installation, connection, or setting. Any method that can achieve its beneficial effects can be implemented. The control box 1, optical cable 2, light box 3, lower light-emitting plate 4, light guide column 5, light-receiving ball 6, upper light-emitting plate 7, reflector 8, outer casing 9, focusing lens 10, expansion tank 11, light-emitting unit 12, controller 13, receiving unit 14, lamp group control board 15, lamp group 16, lamp cover 17, beam splitter 18, beam splitter column 19, optical connector 20, small lens 21, and cooler 22 of the ceiling landscape energy-saving lighting system of the present invention are commercially available. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0042] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
