Description

Technical Field

[0001] The invention belongs to the technical field of starry sky lamps, and in particular relates to a projector starry sky lamp. Background Art

[0002] As people's quality of life continues to improve, smart home products have gradually become a part of daily life, and the emergence of various intelligent devices has greatly improved the user's living experience. Among the many smart home devices, projector starry sky lights have become one of the important products in modern home entertainment, leisure and relaxation, and education scenes due to their unique atmosphere creation capabilities. However, the existing projector starry sky lights still have many deficiencies in technical implementation, which affects their performance, user experience and market competitiveness.

[0003] Existing starry sky lights mainly use traditional light sources and physical projection technology to display starry sky patterns, usually relying on simple LED light sheets or physical hardware image cards. The limitations of this technology lead to a single projection effect, making it difficult to display delicate image details and diverse dynamic effects. At the same time, many devices cannot support precise focal length adjustment, and the projection pattern is prone to blur, affecting the overall visual effect and user experience.

[0004] The existing starry sky lamp projection effects mostly rely on traditional light sources and projection technology, with low image clarity, poor detail performance, and a single image effect, which cannot provide high-quality projection effects. Most starry sky lamps cannot achieve precise focal length adjustment, resulting in blurred projected starry sky patterns, affecting visual effects.

[0005] Many projector star lights lack flexible brightness adjustment functions and cannot automatically adjust the brightness according to different ambient light to adapt to different usage scenarios. At the same time, the contrast adjustment is often not fine enough to truly restore the starlight effect of the night sky.

[0006] Many projector starry sky light devices only provide basic visual effects, but ignore the matching of audio, which greatly reduces the entertainment value of the device. Even if some products provide audio playback function, the sound quality and sound effect performance are often not ideal, which cannot complement the projection effect, and the user experience is greatly reduced.

[0007] Projector star lights usually contain multiple high-power electronic components, such as projection modules, sound systems, LED light sources, etc. These components will generate a lot of heat during long-term operation. Most existing devices are not designed with effective heat dissipation systems, which causes the device to overheat after long-term use, affecting its performance and service life. In some cases, overheating may also cause device failure and reduce user experience.

[0008] Although some modern starry sky light devices are equipped with remote controls or smart control functions, their operation interfaces and interaction methods are still cumbersome and cannot meet the growing demand for intelligence among users. For example, they lack compatibility with smart home systems, and users cannot achieve convenient control through voice assistants or mobile phone applications.

[0009] Existing starry sky lights usually only have simple projection functions, but lack the ability to work in conjunction with other home appliances. They lack personalized control options, such as automatically adjusting projection patterns, light-emitting sheet cards, brightness, sound, etc. according to changes in the user's mood, time, ambient light, etc., resulting in a relatively simple user experience that cannot meet the needs of different scenarios. Summary of the invention

[0010] In view of the technical problems mentioned in the background technology, the purpose of the present invention is to provide a projector starry sky lamp to solve the technical problems mentioned in the above background technology.

[0011] To achieve the above-mentioned purpose, the technical solution provided by the present invention is: a projector starry sky lamp, which includes a mounting shell, a mounting shell groove is recessed inside the mounting shell, a mounting bracket is installed inside the mounting shell groove, a projection component is installed in the middle of the mounting bracket, an intelligent driving component is installed in the front of the mounting bracket, audio components are respectively installed on both sides of the mounting bracket, a rechargeable battery is installed at the rear of the mounting bracket, a mounting cover is installed on the top of the mounting shell, a light emitting opening is opened in the middle of the mounting cover, the upper part of the projection component extends through the light emitting opening, a heat dissipation component is installed on the inner side wall of the mounting shell groove, and the intelligent driving component is electrically connected to the projection component, the audio component, the rechargeable battery and the heat dissipation component, respectively.

[0012] The present invention mainly has the following beneficial effects: it includes components such as an installation shell, an installation bracket, a projection component, an intelligent drive component, an audio component and a rechargeable battery. An installation shell groove is recessed inside the installation shell, and the installation bracket is installed in the shell groove. The projection component and the intelligent drive component are respectively installed on the bracket. The projection component includes a light-emitting lamp head, a projection shell, a liquid crystal display panel, a light-transmitting lens, etc. The projection lamp projects a starry sky image through liquid crystal display technology, and the user can adjust the brightness, focal length, and projection mode. The audio component provides surround sound effects to enhance the starry sky atmosphere, and the intelligent drive component controls functions such as projection, audio and heat dissipation. The heat dissipation component reduces the temperature of the device through the heat dissipation fan blades to ensure stability. The intelligent drive component includes an intelligent control panel and a drive button panel, which has voice control, Bluetooth connection and Wi-Fi remote control functions. Users adjust the lights and music through APP or voice control to create an atmosphere.
