[0002] With the acceleration of modern life and the intensification of urbanization, people's demand for healthy lighting is growing, especially in indoor environments. Traditional lighting equipment often cannot provide sufficient brightness and comfortable color temperature, and also lacks adaptability to environmental changes and personalized adjustment capabilities. In order to solve this problem, intelligent lighting systems came into being, aiming to provide users with a healthy and comfortable lighting environment by precisely controlling the brightness, color temperature and other environmental factors of the light source. Intelligent lighting systems can not only automatically adjust the brightness and color temperature according to changes in ambient light, but also provide customized lighting solutions in different application scenarios.

[0003] However, despite technological advances, existing smart lighting systems still lack accuracy and convenience in terms of environmental monitoring and light source control. First, the existing lighting systems are often not precise enough in controlling ambient temperature, resulting in unstable comfort levels in the indoor light environment. For example, using warm white light at too high a temperature can make people feel bad and may affect their work efficiency, while using cold light at too low a temperature may cause physical discomfort. Lighting is an important factor that affects people's biological clocks and emotions, and different scenes or time periods have different requirements for light intensity and color temperature. Existing lighting systems generally lack an effective mechanism for adjusting light source intensity and color temperature, which limits the application of smart lighting systems in specific scenarios. In addition, existing technologies have not yet fully utilized environmental monitors to monitor and feedback temperature changes in the lighting environment, thereby optimizing lighting performance and product life.

[0004] As described in patent WO2016197880A1, it discloses a control method and device for an intelligent lighting system, which controls the color of the output light by adding an auxiliary detection unit and analyzing environmental information, thereby achieving a better lighting effect. However, although it involves personalized intelligent lighting, the technology does not solve the problems of environmental monitoring and real-time temperature feedback in the intelligent lighting system. In summary, the existing intelligent lighting system has deficiencies in the accuracy of environmental control, the flexibility of light source adjustment, and the comprehensive monitoring of environmental changes.

[0005] Therefore, the inventors of this application found that the above technology has at least the following technical problems in the process of implementing the technical solution of the invention in the embodiment of this application:

[0039] The embodiments of the present application provide an intelligent lighting system to solve the problems in the prior art that the lighting system cannot effectively integrate environmental monitoring functions, especially real-time temperature feedback, lacks precision and flexibility in light source control, and cannot meet the personalized needs for light intensity and color temperature in different scenarios.

[0040] The technical solution in the embodiment of the present application is to solve the above-mentioned crosstalk problem, and the overall idea is as follows:

[0041] By integrating environmental monitoring functions and precise light source control mechanisms, the intelligent lighting system of the present invention can automatically adjust the brightness and color temperature of the light source according to real-time ambient temperature feedback to adapt to the needs of different environments and scenes. Specifically, the present embodiment designs the intelligent lighting system to include a thin and flexible light guide (1), on which a two-dimensional pattern of light extraction microstructures is provided, and a light mixing area is formed between the first surface (2) and the second surface (3) of the light guide (1). At the same time, a side-emitting LED light strip (8) is provided on the second surface (3), which is composed of a plurality of LEDs of different color temperatures and is configured with a flexible printed circuit (7).

[0042] The intelligent lighting system in this embodiment also includes an environment monitoring meter (9), which is arranged at the upper end of the LED light bar (8), and includes a transmission element (11) and a thermosensitive indicating element (12). The indicating material in the thermosensitive indicating element (12) is a mixture of a synthetic polymer material and a wax material, and is configured to move along the transmission element (11) when melted. When the ambient temperature reaches a predetermined threshold (about 18°C ​​to about 25°C), the indicating material will melt and move along the transmission element (11), thereby monitoring the ambient temperature change of the backlight unit in real time and indicating the ambient temperature state of the backlight unit.

[0043] The control unit adjusts the brightness and color temperature of the LED light strip (8) according to the data provided by the environmental monitoring meter (9) to optimize the lighting performance and product life. In this way, when the ambient temperature changes, the intelligent lighting system can automatically adjust the color temperature of the light source to provide a more comfortable lighting environment. For example, a warmer light color temperature is provided in a warm environment, and a colder light color temperature is provided in a cold environment, which solves the problem that the existing lighting system cannot meet the personalized needs of light intensity and color temperature in different scenes.

[0044] In addition, the intelligent lighting system in this embodiment can monitor the temperature of the device in real time by integrating a thermal indicator, and timely adjust the power consumption through the intelligent temperature control system to prevent overheating and extend the life of the device. The thin and soft light guide (1) technology is combined with the design of the light extraction microstructure, the light emission area (5) and other light-emitting surfaces to achieve uniform distribution of light, provide a more comfortable lighting effect, reduce glare and shadows, and improve user experience.

[0045] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0047] The intelligent lighting system of the present invention is provided with a light guide plate, and further comprises a first surface (2), that is, the light emitting surface of the lighting element, having a plurality of light extraction microstructures distributed in the area. The light extraction microstructure can be any optical element designed for light propagation in the light guide plate and gradually extracts light from the light guide plate so that the light emission area (5) can emit light. The light extraction microstructure can be formed by light scattering white paint or pigment dots on ink randomly or quasi-randomly distributed on the light emitting surface.

[0048] The light extraction microstructure can also be formed by surface microstructure or light scattering texture. The light scattering extraction points or patterns can be applied to the first surface (2), i.e. the light emitting surface. The light extraction microstructure can also be formed by microscopic volume scattering particles embedded in the substrate material.

[0049] The light emitting area (5) of the first surface (2) may have any two-dimensional shape, which may in turn include a plurality of smaller light emitting areas (5) arranged and shaped in any suitable manner. For example, the first surface (2) may include any geometric shape, symbol, character, letter, word, mark, image and pattern. The first surface (2) may also be configured not to represent a specific shape or visible pattern, and may simply provide uniform or non-uniform light emission for lighting or visual effect functions.

[0050] The light emitting region (5) of the first surface (2) may include a layer of photoluminescent material or phosphor material. Such a material may be configured to absorb light of a first wavelength and re-emit light of a second wavelength different from the first wavelength, preferably the second wavelength being greater than the first wavelength. For example, such a material may absorb at least a portion of blue light emitted by certain types of LEDs and re-emit the energy of such blue light in the form of observable white light.

[0051] The first surface (2) of the present intelligent lighting device can further incorporate various color filters, inks, dyes or other devices or substances that change the color of the extracted light. It can also incorporate polarizing elements, fluorescent elements, fluorescent elements, light scattering or diffusing elements, etc., which can be provided as a separate layer or incorporated into the bulk material of the optical element of the LED source, such as on the light coupling device (4).

[0052] As attached Figure 1 As shown, light is emitted by the LED light bar (8), enters the optical coupling device (4) according to the optical path shown in the figure, is coupled into more concentrated light, and is emitted to the inner side of the first surface (2). Obviously, a reflection device (6) is provided on the inner side of the second surface (2), and then the light is uniformly reflected to the light emission area (5), and then uniform illumination light is emitted to the first surface (2), that is, the light emitting surface. The uniform area illuminated by the light is the light emission area (5).

[0053] Embodiment 2

[0054] The light-emitting element of the intelligent lighting system is provided with an environmental monitoring meter (9), which is arranged at the upper end of the LED light bar (8), and comprises: a transmission element (11) and a thermal indicator element (12). The thermal indicator element (12) is a solid indicator material, which is a mixture of a synthetic polymer material and a wax material, and is configured to move along the transmission element (11) when melted.

[0055] The synthetic polymer material herein comprises a blend of two or more polymers having side chain crystallinity (SCC). A polymer having side chain crystallinity (SCC) may also be used in combination, selected from the following polymers or copolymers of crystallizable side chains: a group consisting of C4-30 aliphatic groups; a C6-30 aromatic group; a straight chain aliphatic group having at least 10 carbon atoms; a combination of at least one aliphatic group and at least one aromatic group, the combination having 7 carbon atoms to about 30 carbon atoms; a C10-C22 acrylate; a C10-C22 methacrylate; acrylamide; methacrylamide; vinyl ether; vinyl ester; a fluorinated aliphatic group having at least 6 carbon atoms; and a para-alkylstyrene group, wherein the alkyl group has about 8 carbon atoms to about 24 carbon atoms.

[0057] Embodiment 3

[0058] In this embodiment, we propose a control method for an intelligent lighting system, which achieves a more comfortable and energy-saving lighting effect by monitoring the ambient temperature in real time and adjusting the output of the lighting module accordingly. The core of the system is the temperature detection module, which is responsible for capturing the temperature changes of the surrounding environment and transmitting these data to the information processing module in real time. The information processing module then analyzes these temperature data to determine whether the current temperature falls within a specific range we preset, namely the low temperature threshold of 18℃ to 20℃ and the warm temperature threshold of 21℃ to 30℃. This judgment process is crucial to the automatic adjustment function of the system because it determines what color temperature of light the lighting module should emit next.

[0059] The information processing module determines the state of the ambient temperature and sends this judgment information to the control module. The control module, as the command center of the system, sends corresponding working signals to the lighting module based on the received temperature status information. The lighting module then responds to these signals and adjusts the light color it emits to adapt to the current ambient temperature. For example, when the ambient temperature is low, the lighting module will emit a warmer light color - 2700K to 3000K to create a warm atmosphere; when the ambient temperature is high, it will emit a cooler light color - 5000K to 6500K to help reduce the heat sensation in the space.

[0060] The system also includes an environmental indicator that can intuitively display the current ambient temperature. This indicator reflects temperature changes by indicating the movement of the material, and the user can intuitively see the rise and fall of the temperature. More importantly, when the ambient temperature exceeds the preset threshold of 65°C, the temperature detection module will automatically control the lighting module to stop working to prevent overheating from causing damage to the circuit (7) and the lamp.
