Description

Technical Field

[0001] The present invention relates to the technical field of lighting systems, and in particular to a ceiling landscape energy-saving lighting system. Background Art

[0002] Currently, lighting systems are installed on ceilings to provide lighting and cooperate with the scenery below the ceiling to achieve a better landscape effect. A variety of lighting devices for ceilings are disclosed in the prior art. For example, a large-area exhibition hall ceiling lighting device proposed in a Chinese invention application with the publication number CN118640438A includes a top frame, on which a lifting motor is installed. The lifting motor is connected to a lamp panel through a cable. A first LED lamp group is installed on the bottom surface of the lamp panel. A circular slot is provided at the center of the top surface of the lamp panel, and a light filter cylinder is inserted into the circular slot. A second LED lamp group is installed inside the light filter cylinder. Several reflector plates are pivotally connected to the top of the light filter cylinder, which is convenient for finely adjusting the illuminance in the exhibition hall.

[0003] However, both the first LED lamp group and the second LED lamp group of the above ceiling lighting device are directly installed on the ceiling, resulting in a relatively large overall volume and weight of the lighting device installed on the ceiling. The excessive volume and weight increase the risk of falling. Since the service life of the LED lamp group is limited, when the LED lamp group is damaged, the relatively high installation height makes the repair and replacement of the ceiling lighting device difficult. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a ceiling landscape energy-saving lighting system that uses an optical fiber to conduct light, separates the light source part and the lighting part, reduces the risk of falling, facilitates repair and replacement, and improves reliability.

A light source unit is installed inside the control box, and the light source unit is used for emitting light. The input end of the optical cable is optically 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. An light outlet communicating with the installation chamber is provided on the lower end surface of the light box. The lower light-emitting plate is installed on the light outlet. The lower end of the light guide column is optically connected to the lower light-emitting plate.

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-shielding layer. The lower surface of the lower light-emitting plate is arc-shaped, so that the lower light-emitting plate has a lens effect; when there is sufficient sunlight outside during the day, the sunlight shines on the light inlet ball and is conducted to the lower light-emitting plate through the light guide column, and is emitted downward from the lower light-emitting plate to supplement the lighting below the ceiling. At this time, the light source unit inside the control box is turned off to achieve the purpose of energy saving; when the external sunlight illumination is insufficient, the light source unit inside the control box is turned on, and the light source unit emits light. The emitted light is conducted to the upper light-emitting plate through the optical cable and emitted outward. The light emitted by the upper light-emitting plate is gathered after passing through the lens effect of the lower light-emitting plate and then emitted downward to the ceiling for lighting; compared with the prior art, the light source lamp group is no longer directly installed on the ceiling, but is centrally installed at a lower position, reducing the overall volume and weight of the lighting device installed on the ceiling, reducing the risk of falling.

Detailed implementation manners

[0018] For ease of understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided so that the disclosure of the present invention is more thorough and comprehensive.

[0019] Example 1, as shown in Figures 1 to 6As shown in the figure, 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 plate 4, a light guide column 5, a light inlet ball 6, and an upper light-emitting plate 7. A light source unit is installed inside the control box 1 for emitting light. The input end of the optical cable 2 is optically connected to the output end of the light source unit. The light box 3 is installed below the ceiling. An installation chamber is provided inside the light box 3. An light outlet communicating with the installation chamber is provided on the lower end surface of the light box 3. The lower light-emitting plate 4 is installed on the light outlet. The lower end of the light guide column 5 is optically connected to the lower light-emitting plate 4. The upper end of the light guide column 5 is provided with the light inlet ball 6. The light inlet ball 6 extends above the ceiling. The upper light-emitting plate 7 is installed in the middle of the installation chamber of the light box 3. The upper light-emitting plate 7 is located above the lower light-emitting plate 4. The output end of the optical cable 2 is optically connected to the upper light-emitting plate 7. It also includes a reflecting plate 8. The reflecting plate 8 is installed on the top of the installation chamber of the light box 3. The reflecting plate 8 is located above the upper light-emitting plate 7.

[0020] The control box 1 is installed on the ground or in a control room at a lower position. 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-shielding layer. The lower surface of the lower light-emitting plate 4 is arc-shaped, so that the lower light-emitting plate 4 has a lens effect. The reflecting plate 8 reflects the light emitted by the lower light-emitting plate 4 and the upper light-emitting plate 7 downward to improve the lighting effect. When there is sufficient sunlight outside during the day, the sunlight shines on the light inlet ball 6 and is conducted to the lower light-emitting plate 4 through the light guide column 5, and is emitted downward from 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 to achieve the purpose of energy saving. When the sunlight illumination is insufficient outside, the light source unit inside the control box 1 is turned on. The light source unit emits light, and the emitted light is conducted to the upper light-emitting plate 7 through the optical cable 2 and emitted outward. The light emitted by the upper light-emitting plate 7 is gathered through the lens effect of the lower light-emitting plate 4 and emitted downward to the ceiling for lighting. Compared with the prior art, the light source lamp group is no longer directly installed on the ceiling, but is centrally installed at a lower position, reducing the overall volume and weight of the lighting device installed on the ceiling, reducing the risk of falling. When the light source lamp group is damaged, the lower and centrally installed light source lamp group makes maintenance and replacement more convenient.

[0021] Embodiment 2, as Figures 1 to 7 shown, on the basis of Embodiment 1, it further includes an outer box body 9 and a condenser lens 10. A light-receiving chamber is provided inside the outer box body 9. The light inlet ball 6 is located in the middle of the light-receiving chamber of the outer box body 9. The condenser lens 10 is installed on the top of the light inlet ball 6. The light-receiving chamber of the outer box body 9 is filled with a transparent fluorescent liquid. It also includes an expansion pot 11. The expansion pot 11 is installed outside the outer box body 9. The expansion pot 11 is higher than the condenser lens 10. The bottom of the expansion pot 11 is communicated with the light-receiving chamber of the outer box body 9.

[0022] When the light-receiving chamber of the outer casing 9 is filled with the fluorescent liquid, the liquid level of the fluorescent liquid in the expansion pot 11 is higher than that of the condenser lens 10. Thus, when the fluorescent liquid in the outer casing 9 contracts at low temperature, the fluorescent liquid in the expansion pot 11 supplements the outer casing 9. When the fluorescent liquid in the outer casing 9 expands at high temperature, the fluorescent liquid in the outer casing 9 enters the expansion pot 11 for buffering. Adjust the position of the light inlet ball 6 so that the light inlet ball 6 is within the focal range of the condenser lens 10, enabling the condenser lens 10 to concentrate a large area of sunlight onto the light inlet ball 6, increasing the amount of sunlight entering, and thus improving the lighting effect of the lower light-emitting plate 4. The fluorescent liquid absorbs ultraviolet rays for energy storage and excitation, which can reduce the ultraviolet intensity below the ceiling. At night, the fluorescent liquid emits light, and the fluorescence is conducted through the light inlet ball 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 below the ceiling, which is suitable for low-illumination usage scenarios such as when there is no one below the ceiling, and further saves energy and reduces consumption.

The light-emitting unit 12 includes a lamp group control board 15, a plurality of lamp groups 16, a lamp cover body 17, a beam splitter 18, a plurality of beam splitting columns 19, and an optical connector 20. The upper light-emitting plate 7 is composed of a plurality of small light-emitting plates arranged in a matrix. A plurality of optical fibers are arranged inside the optical cable 2, and the output ends of the plurality of optical fibers are respectively connected to the plurality of small light-emitting plates of the upper light-emitting plate 7. The lamp group control board 15 is electrically connected to the controller 13. A plurality of lamp groups 16 are installed in a matrix on the lamp group control board 15.

It further includes a plurality of small lenses 21, and the plurality of small lenses 21 are respectively installed in the plurality of installation grids of the lamp cover body 17. The plurality of lamp cover bodies 17 are respectively located between the plurality of beam splitting columns 19 and the plurality of lamp groups 16. The lamp group 16 is a multi-color LED lamp group. It further includes a cooler 22, and the cooler 22 is installed in the control box 1.

[0024] The cooler 22 cools down and dissipates heat from the light-emitting unit 12 and the controller 13 in the control box 1, improving the reliability of the light-emitting unit 12 and the controller 13. Multiple light-emitting units 12 can be provided. The multiple light-emitting units 12 are respectively connected through multiple optical cables 2, and multiple light boxes 3 are provided. The multiple light boxes 3 are respectively arranged at different positions on the ceiling to achieve distributed overall lighting below the ceiling. The receiving unit 14 is connected to the upper-level control system through the communication module. Staff can remotely send a control program to the receiving unit 14, and the controller 13 executes the control program to control the multiple light-emitting units 12, turning on or off the specified multiple light-emitting units 12. The light emitted by the light-emitting unit 12 is output through the optical cable 2, so that the upper light-emitting plate 7 in the specified light box 3 emits light, achieving different lighting effects.

[0025] Furthermore, after receiving the control electrical signal from the controller 13, the lamp group control board 15 controls the specified multiple lamp groups 16 to turn on or off. When the multiple lamp groups 16 are turned on and emit light, the multiple installation grids and multiple small lenses 21 of the lamp cover body 17 will respectively gather and separate the light emitted by the multiple lamp groups 16, so that the light emitted by the multiple lamp groups 16 is input into the optical fiber of the optical cable 2 through the corresponding optical paths of the multiple light splitting columns 19 and the light splitting plate 18 and the optical connector 20, so that the light is input along the corresponding optical fiber to the specified multiple small light-emitting plates on the upper light-emitting plate 7, causing the specified small light-emitting plates to emit light, achieving different lighting effects, and regularly causing the multiple small light-emitting plates on the upper light-emitting plate 7 to emit light, capable of displaying characters, pictures, etc., achieving an advertising effect, or cooperating with the scenery below the ceiling, the multiple small light-emitting plates form different shapes, improving the landscape effect. By adjusting the light-emitting colors of the multiple lamp groups 16, the multiple small light-emitting plates on the upper light-emitting plate 7 emit light of different colors, thus forming color patterns and characters, further improving the advertising and landscape effects.

[0026] Such as Figures 1 to 10As shown in the figure, in a ceiling landscape energy-saving lighting system of the present invention, during operation, first, the control box 1 is installed on the ground or in a control room at a lower position. When there is sufficient sunlight outside during the day, the sunlight passes through the condenser lens 10 and irradiates onto the light inlet sphere 6, and is conducted to the lower light-emitting plate 4 through the light guide column 5, and is emitted downward from 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 to achieve the purpose of energy conservation. At the same time, the fluorescent liquid absorbs ultraviolet rays for energy storage and excitation, which can reduce the ultraviolet intensity below the ceiling. Then, at night, the fluorescent liquid emits light, and the fluorescence is conducted to the lower light-emitting plate 4 through the light inlet sphere 6 and the light guide column 5, so that the lower light-emitting plate 4 emits fluorescence to illuminate below the ceiling, which is suitable for low-light usage scenarios such as when there is no one below the ceiling. Then, when the outside sunlight illumination is insufficient, the staff can remotely send a control program to the receiving unit 14, and the controller 13 executes the control program to control multiple light-emitting units 12, so that the specified multiple light-emitting units 12 are turned on or off.

The fluorescent liquid absorbs ultraviolet rays for energy storage and excitation, which can reduce the ultraviolet intensity below the ceiling. At night, the fluorescent liquid emits light, so that the lower light-emitting plate 4 emits fluorescence to illuminate below the ceiling, which is more energy-saving and consumption-reducing. 4. By controlling the emission of different upper light-emitting plates 7, words, pictures, etc. can be displayed to achieve an advertising effect, or cooperate with the scenery below the ceiling, and multiple small light-emitting plates form different shapes to improve the landscape effect.
