DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0025] See also Figure 1-4 The present invention provides the following technical solutions: an indoor unit of an air conditioner with a lighting system, comprising an indoor unit casing 001, an indoor unit control board 002, and a lighting system 003. The lighting system 003 is installed on the indoor unit casing 001 and is electrically connected to the indoor unit control board 002 via an electric wire 004. The indoor unit control board 002 comprises a power module, a control module, and a frequency conversion module. It can control the operation of various electrical components of the air conditioner and supply power to the lighting system 003. It can control the lighting mode of the lighting system 003 and control parameters such as the brightness, color temperature, and color of the lighting system 003. It can be a simple dimmer or switch, or a complex intelligent control system. The lighting system 003 is electrically connected to the power module and the control module of the indoor unit control board 002. The lighting system 003 comprises a light-emitting device 011, a lamp cover 012, and a light-regulating device 013.

[0026] The light emitting device 011 is installed inside the inner machine casing 001, and the number can be one or more; its components can be incandescent lamps, fluorescent lamps, LED lamps, xenon lamps, high pressure sodium lamps, metal halide lamps, lasers, etc., preferably LED lamps.

[0027] The lamp cover 012 is installed around the light emitting device 011 to adjust the direction of light propagation. The material can be metal, plastic, reflective glass, or a combination of materials with reflective effects. The structure can be U-shaped or spherical. A single-layer structure can be adopted: a simple U-shaped lamp cover 012 is composed of a layer of material, which can be flat or curved; a multi-layer structure can also be adopted. The U-shaped lamp cover 012 can be designed as a multi-layer structure to enhance the reflection effect of light and control the propagation of light. The multi-layer structure can adopt a combination of different materials, such as a combination of an inner layer of transparent material and an outer layer of reflective material. Surface treatment: The surface of the reflector can be specially treated, such as coating, spraying, etc., to enhance the reflection effect, improve durability or achieve specific optical properties.

[0028] The light shaping device 013 is installed in front of the light emitting device 011 and the lamp 012 to adjust the shape and direction of light. The light shaping device 013 can be a lens: a lens can adjust the focus and dispersion of light, thereby changing the shape and projection angle of light. For example, a convex lens can focus light to a point or form a concentrated spot, while a concave lens can disperse light to a wider angle. The light shaping device 013 can also be a concentrator or diffuser: concentrators and diffusers can adjust the shape of light by changing the dispersion angle of light. A concentrator can concentrate light into a smaller area, while a diffuser can spread light over a larger area. Alternatively, the light shaping device 013 can be a mirror or reflector: a mirror or reflector can change the direction and angle of light propagation, thereby projecting light in a specific shape. These can be plane mirrors, curved mirrors, or reflective surfaces with a specific curvature. The light shaping device 013 can also be a light blocker, which can block or limit the range of light propagation, thereby projecting light in a specific shape. This light blocker can be a fixed sunshade, partition, or adjustable light limiting device.

[0029] As a preferred implementation of this embodiment, Figure 3-4As shown, the light emitting device 011 adopts the lighting lamp 021 shown in the figure, and the light-shaping device 013 adopts the refractive reflective component 020 shown in the figure. The refractive reflective component 020 has a hemispherical surface 0201, a trapezoidal surface 0202, and a transition surface 0203. The trapezoidal surface 0202 has four surfaces, which together form a cover. The trapezoidal surface 0202 is connected to the hemispherical surface 0201 through the transition surface 0203. The transition surface 0202 is an annular arc surface structure, thereby forming a light-shaping device 013. A conical cavity 0204 is provided in the middle of the light-shaping device 013. The conical cavity 0204 is provided in the middle of the light-shaping device 013. 204 is used to refract and reflect light within the highly transmissive, highly refractive material, adjusting the direction of light emission. The hemispherical surface 0201 has a groove, into which the illuminating lamp 021 is placed. The hemispherical surface 0201, the trapezoidal surface 0202, and the transition surface 0203 are all coated with a reflective coating 023, but the conical cavity 0204 is uncoated. Light emitted by the illuminating lamp 021 undergoes multiple refractions and reflections within the light-adjusting device 013 before exiting from one side of the hood. If the hood is T-shaped, the emitted light will propagate forward in a gradually enlarging trapezoidal structure. Rotating shafts 022 are symmetrically positioned on either side of the hemispherical surface 0201. These connect the light-adjusting device 013 to the inner housing 001. Adjusting the rotating shafts 022 changes the position of the light-adjusting device 013, thereby adjusting the angle of the lighting system and, therefore, the position and shape of the light illuminating the roof. The rotating shaft 022 can be cylindrical or polyhedral, so long as it can realize the rotation function and the fixing function.

[0030] The user sends a light-on command through the air conditioner wired controller or air conditioner remote control: the indoor unit control board 001 receives the command, starts the power module to power the light-emitting device 011, and projects the light onto the roof; the user sends a shut-down command: after receiving the shut-down command, the indoor unit control board 001 will immediately execute the operation of shutting down the power module to turn off the light.

[0031] Users can also set the brightness, color, and timer switch functions of the lights through the air conditioner wired controller or remote control. The control module of the indoor control board 001 controls the brightness, color, and switch time of the lights according to the instructions received.

[0032] The air conditioner can also automatically adjust the lighting tone based on the ambient temperature and humidity detected by the air conditioner, changing the user's perception of temperature and providing a more comfortable living environment and air conditioning experience. For example, when the detected ambient temperature is greater than a and the humidity is greater than b, the lighting is controlled to a cool tone, with a color temperature c proportional to the ambient temperature a: c = ta. Here, a can be 30°C, b is 50%, c can be 6000K, and t is a coefficient, which can be 200. When the detected ambient temperature is less than d and the humidity is less than e, the lighting is controlled to a warm tone, with a color temperature f inversely proportional to the ambient temperature d: f = d / m. Here, d can be 20°C, e is 30%, f can be 3000K, and m is a coefficient, which can be 150. When the detected d is greater than or equal to the ambient temperature ≤ a, and f is greater than or equal to the humidity ≤ e, the lighting is controlled to a normal tone with a color temperature g, which can be 4000K. Example 2

[0033] The lighting system 003 in this embodiment is a separate module that can be attached to the inner housing 001. Fixing components secure the lighting system 003 to the inner housing 001, and electrical wiring can be connected to the power supply. The lighting system 003 can be secured to the inner housing 001 using any fixing method, such as screws, and the power supply can be connected using any connection method, such as plugging. The lighting system 003 includes a control module and a power module. The control module controls the on / off switching of the light-emitting devices, and the power module connects to the light-emitting devices to provide power. The control module enables remote control, enabling operations such as turning the lighting on and off, dimming, and adjusting the color temperature.

[0034] Remote control methods are as follows:

[0035] First, a remote connection must be established, connecting the control device (such as a smartphone, tablet, or computer) to the controlled lighting system 003. This can be achieved via a wireless network (such as Wi-Fi, Bluetooth), the internet, or other communication protocols. Sending remote commands: The control device sends control commands to the control module of the lighting system 003 via the remote connection. These commands can be for operations such as turning lights on and off, dimming, or adjusting the color temperature. Commands can be sent via dedicated applications, web interfaces, or communication protocols. Transmission and Reception: Control commands are transmitted to the lighting system 003 via the remote connection. Upon receiving the commands, the lighting system 003 interprets and processes them. Lighting Control: The lighting system 003 performs the corresponding operations based on the received commands, such as turning lights on or off, adjusting brightness, or adjusting color temperature. Once the control module receives these commands, it can also implement control through a connection to an external control device. Status Feedback: The lighting system 003 can provide feedback on execution results or current status to the control device to ensure the accuracy and reliability of remote control. This can be achieved by sending response messages, status updates, or data feedback.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
