[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] This utility model is a clock digital display projection ambient light, such as... Figures 1 to 7 As shown, including The clock housing 10 has an internal mounting cavity formed inside it; A backlight module, disposed in an inner cavity, includes a spherical light-reflecting surface disposed at the bottom of the inner cavity and a backlight source. The backlight source is arranged along the radial direction of the spherical light-reflecting surface, and the focal point of the backlight source is located at the midpoint of the radius. The light source of the backlight module is an LED lamp bead 20, an OLED light source, or a Mini LED array. The digital display unit is a light-transmitting display panel 30, which is disposed in the mounting cavity and located in the light propagation path of the backlight module. It is used to receive the light transmitted from the backlight module and form an electronic light signal carrying projection information. The imaging observation surface is an acrylic panel 40, which is disposed on the top surface of the clock housing 10 and is located on the electronic light signal propagation path of the digital display unit, and is used to receive the electronic light signal to form an observable projected image on the observation surface. An ambient light source is installed inside the mounting cavity, with its light-emitting surface facing the imaging observation surface.
[0021] In use, the backlight source emits light, which is reflected by the spherical light-reflecting surface to form reflected light. The digital display unit is positioned on the propagation path of the reflected light from the backlight module. This reflected light projects the display information for different occasions onto the imaging observation surface in a front-view manner, forming a clear and observable projected image. Users can then easily observe information such as the time projected. Simultaneously, the ambient light source is controlled to emit light, which shines directly onto the imaging observation surface and blends with the projected image to present various lighting effects. Compared to traditional clocks that use high-brightness, always-on digital tubes to adapt to daytime conditions and cause light pollution that affects sleep at night, this device intelligently integrates clock display, projection functions, and ambient lighting. The projection is clearly visible, and with the ambient light, the imaging observation surface is illuminated in full screen. This satisfies the needs for time viewing and projection at different times of day, while also creating a comfortable environment through controllable lighting effects.
[0022] Furthermore, in some embodiments of this utility model application, such as Figure 3 , 4 As shown in Figures 5, 6, and 7, the backlight module includes a base box 50 disposed at the bottom of the mounting cavity. A curved reflector 60 is disposed inside the base box 50. The spherical light reflecting surface is the reflecting surface of the curved reflector 60. The backlight source is disposed on the upper part of the inner sidewall of the base box 50, and the light emitting surface of the backlight source faces the curved reflector 60. The curved reflector 60 converges the light emitted by the backlight source and guides it to the direction of the digital display unit.
[0023] In this embodiment, the base box 50 provides a stable mounting reference for the curved reflector 60 and the backlight source. The backlight source is located on the upper part of the inner side wall of the base box 50 and faces the curved reflector 60. The light from the backlight source can be directly projected onto the reflective surface. The curved reflector 60 can efficiently converge and diverge the light, and direct it to the digital display unit, so that the light is concentrated on the effective area of the digital display unit, improving the utilization rate of the light source. At the same time, it ensures that the incident light is uniform, providing a stable and sufficient lighting basis for the digital display unit to form a clear electronic light signal, thereby optimizing the clarity and brightness uniformity of the projected image.
[0024] Furthermore, in some embodiments of this utility model application, such as Figure 3 , 4 As shown in Figures 5, 6, and 7, the ambient light source is an LED light source panel 70 disposed on the outer periphery of the base box 50. The LED light source panel 70, located on the outer periphery of the base box 50, allows for convenient installation and positioning, improving structural compactness. Its surrounding layout creates omnidirectional illumination, with light uniformly and directly illuminating the imaging observation surface, naturally blending with the projected image from the digital display unit. This not only supplements the lighting on the observation surface to optimize the projection viewing experience but also creates rich and layered ambient lighting effects, adapting to the lighting and shadow requirements of different scenes.
[0025] Furthermore, in some embodiments of this utility model application, a lens is provided on the top surface of the bottom box 50, which can re-regulate the light guided by the backlight module, reduce light scattering, improve light concentration and uniformity, and ensure that the digital display unit receives stable illumination.
[0026] Furthermore, in some embodiments of this utility model application, such as Figure 5 , 6 As shown in Figure 7, a control board 80 is provided in the installation cavity. The control board 80 is connected to the digital display unit, the backlight source, and the ambient light source respectively to achieve centralized control. It can synchronously coordinate the working status of each component, accurately respond to commands, ensure the orderly linkage of projection and lighting functions, and improve the stability and ease of operation of the device.
[0027] Furthermore, in some embodiments of this utility model application, such as Figure 2 , 3 As shown in Figures 4, 5, 6, and 7, a control button 90 is connected to the front side of the control board 80, and a button slot is provided on the clock housing 10. The control button 90 is exposed on the outside of the clock housing 10 through the button slot, making it convenient for users to operate directly to set the time and adjust the light effect.
[0028] Furthermore, in some embodiments of this utility model application, such as Figure 4 , 5As shown in Figures 6 and 7, a storage battery 100, a switch 110, and a voice broadcasting device 120 are respectively connected to the control board 80 in the installation cavity. The voice broadcasting device 120 can broadcast the time as needed, enriching its functions.
