Detailed ways

Embodiment one

The inside of the car door is the most concerned position for elevator passengers, but due to elevator safety reasons, commonly used flat-screen TVs cannot be placed in this position. The use of micro-projection as a playback method is not only energy-saving and environmentally friendly, but also can display the image on the inside of the car door where the elevator passengers have the most eyes, thereby increasing the attention of the playback content and providing flexible advertising services for merchants.

Using the front projection technology to install the projector inside the elevator can display the image at the position of the car door. This embodiment provides an elevator image system, including an image playback device and a projector, wherein: the image playback device is used to play images, and the images can include pictures or video content; the projector is arranged in the car of the elevator, and The image playback device is connected to project the image to the inner side of the car door. In this embodiment, the projector may be a miniature projector using light emitting diodes as light sources.

In this embodiment, the projector may be located at the front or rear of the inner roof of the car, or above the rear wall of the car. Taking the projector located behind the inner roof of the car as an example, FIG. 1 is a schematic diagram of Embodiment 1 of the elevator imaging system of the present invention, where the projector is located behind the inner roof of the car. As shown in FIG. 1 , the projector 101 is installed obliquely, and projects an image onto the inner side of the car door 103 of the elevator. The situation that the projector 101 is located in other positions in the car is similar to this, so no repeated description will be given.

In this embodiment, a special projection screen 105 can be set inside the car door 103 at the same height as a normal person's eye-level, that is, about 165 cm vertically from the bottom of the car, to improve the brightness and quality of the picture. In addition, the projection screen 105 can also be made by coating materials that increase reflectivity, such as titanium dioxide nanopowder, or by performing appropriate treatment on the corresponding position inside the car door, such as forming a microstructure with enhanced forward diffuse reflection.

In this embodiment, the elevator image system can also be provided with a deflection device 107 in front of the projector, such as a deflection lens group, for projecting the image onto the projection screen. By setting the deflection device 107, the flexible setting of the position of the projector 101 can be realized. In addition, the deflection device 107 may further perform size adjustment and/or keystone correction on the projected image.

Fig. 2 is a schematic diagram of an embodiment of the elevator imaging system of the present invention, a projector installed above the rear wall of the elevator. As shown in FIG. 2 , an image or video is projected onto a projection screen 105 through a deflection device 107 , that is, a set of optical lenses. Fig. 3 is a schematic diagram of an embodiment of the elevator imaging system of the present invention, a projector installed behind the inner roof of the elevator. Fig. 4 is a schematic diagram of a projector installed in front of the inner roof of the elevator according to an embodiment of the elevator imaging system of the present invention. As shown in FIG. 4 , by installing the projector 101 in front of the inner roof of the elevator, it is possible to prevent the people taking the elevator from covering the projected image, thereby further improving the projection quality.

For the sake of clarity, no video playback device is shown in FIGS. 1-4. In this embodiment, the image playback device may include an image content storage medium for storing the image content to be played.

In this embodiment, the projector should meet the following requirements: (1) small in size to meet the narrow requirements of the interior space of the car; (2) low in noise so that the environment for the passengers of the elevator is comfortable; Fast, so that the projection light source can be quickly turned off when the car door is opened so as not to affect the entry of elevator passengers, and the light source is turned on as soon as possible when the elevator door is closed to effectively use the running time of the elevator; (4) Long life, to reduce system maintenance costs.

In this embodiment, the projector adopts a miniature projector using light-emitting diodes as light sources. The micro-projector with light-emitting diodes as the light source reduces the high-power projection bulbs, thereby avoiding the noise caused by the heat dissipation of the fan, and achieves the effect of low noise; because it does not need preheating and cooling, it can work in real time, thus achieving The switching effect is fast, and the lifespan of the miniature projector using light-emitting diodes as the light source is longer than that of the traditional projector, and the maintenance cost is lower.

The core components of the micro-projector include a light-emitting diode light source, a light modulator, and a lens system. The light source may be, but not limited to, a white light-emitting diode light source or a light-emitting diode light source of red, green and blue three-color light sources. The light modulator is connected to the light-emitting diode light source, and may be, but not limited to, a light modulator based on Liquid Crystal on Silicon (LCoS for short) or a microstructured Digital Light Processor (DLP for short). The lens system is connected with the light modulator, and includes a size adjustment subsystem and a keystone correction subsystem, which are used for adjusting the size of the image projection and performing keystone correction on the image projection.

In this embodiment, a technical solution of using a micro-projector to project images inside the car door is proposed, which achieves the effect of improving the attention of the image content without affecting the appearance of the car door while ensuring the safety of the elevator.
