Description
Technical Field
The utility model relates to an optical communication device especially relates to a projection type optical communication device.
Background
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art for the purposes of describing the present disclosure.
Optical communication devices are also referred to as optical labels, and these two terms are used interchangeably herein. The optical label can transmit information through different light emitting modes, has the advantages of long identification distance and loose requirements on visible light conditions, and the information transmitted by the optical label can change along with time, so that large information capacity and flexible configuration capacity can be provided. Compared with the traditional two-dimensional code, the optical label has longer identification distance and stronger information interaction capacity, thereby providing great convenience for users.
The optical label may generally include a controller and at least one light source, and the controller may drive the light source through different driving modes to realize different light emitting modes, so as to transmit different information to the outside. Fig. 1 shows an exemplary optical label 100 comprising three light sources (first light source 101, second light source 102, third light source 103, respectively). Optical label 100 further comprises a controller (not shown in fig. 1) for selecting a respective driving mode for each light source in dependence on the information to be communicated. For example, in different driving modes, the controller may control the manner in which the light source emits light using different driving signals, such that when the optical label 100 is photographed using the imaging-capable device, the image of the light source therein may present different appearances (e.g., different colors, patterns, brightness). By analyzing the imaging of the light sources in the optical label 100, the driving pattern of each light source at the moment can be analyzed, so that the information transmitted by the optical label 100 at the moment can be analyzed. The optical label 100 may have a length dimension or a width dimension of, for example, several centimeters to several tens of centimeters.
The optical label identification device may be a mobile device carried by a user, such as a mobile phone with a camera, a tablet computer, smart glasses, a smart watch, and the like. In many cases, the identification device needs to acquire multiple images containing the optical label by continuously capturing images of the optical label through a camera thereon, and analyze the image of the optical label (or each light source in the optical label) in each image through a built-in application program to identify the information transmitted by the optical label.
When a user identifies an optical label using an identification device, it is often the case that the user first finds the optical label by the naked eye and then identifies the information conveyed by the optical label using the identification device. This situation is common when a user identifies an optical label using a cell phone. However, since optical labels typically have a large identification distance (e.g., for an optical label having a length dimension or width dimension of about 10 centimeters, it is possible to identify the optical label by an identification device within a range of at least 20 meters), sometimes a user cannot quickly find the optical label present in his field of view by the naked eye that can be identified by the identification device. For example, in an environment where ambient light is insufficient such as at night or in the evening, since the shape and color information of the optical label itself are hardly perceived by human eyes, the user mainly finds the optical label by the features such as the number, shape, and relative positional relationship of the light sources in the optical label. However, due to various light disturbances in the surrounding environment, it may be difficult for a user to quickly find the light labels in his field of view with the naked eye. This may affect the user's interaction with the optical label and thus the user's experience of use.
Therefore, there is a need for an optical label that is easily discovered by a user, particularly in low light environments.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the present invention is further described in detail by the following embodiments with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Fig. 2 shows a front view of a projection type optical label according to an embodiment of the present application, which comprises a housing, three data light sources 201, 202, 203 located on the housing, a projection light source (not shown in fig. 2) located in the housing. The three data light sources 201, 202 and 203 are used for transmitting data information outwards through different light emitting modes or working modes under the control of the controller. The controller can be used to control the data light source and/or the projection light source in the optical label, which may be integrated into the housing of the optical label, but it will be appreciated that the controller may also be another separate component located outside the optical label and may be coupled to the optical label. The projection light source is a light source for realizing a projection function, and is not used for transmitting data information to the outside.
In order to implement the projection function by means of the projection light source, the housing of the optical label can be designed with one or more transparent or hollowed-out portions at its rear side and/or edge. In the present application, the "front side" of the optical label or its housing refers to the side in the same direction as the light emitting direction of the optical label, i.e. the side where the data light source of the optical label is located; the "rear side" of the optical label or its housing refers to the side opposite to the light emitting direction of the optical label, which is also the side adjacent to the surface on which the optical label is mounted; the "edge" of the optical label or its housing refers to the connecting portion between the "front side" and the "rear side". When a projection light source disposed inside the optical label housing emits light, the light can pass through the transparent portion or the hollow portion and reach a surface (e.g., a wall surface) on which the optical label is mounted, thereby projecting a corresponding pattern on the surface.
FIG. 3 illustrates a side view of a projective optical label according to one embodiment of the present application. As shown in fig. 3, the housing of the projection type optical label includes a front case 302 made of an opaque material, a rear case 303 made of an opaque material, and a transparent portion 304 (appearing as a trapezoid in fig. 3) between the edges of the front case and the rear case. In the present application, the "front case" refers to the same side of the optical label case as the light emitting direction, and the "rear case" refers to the opposite side of the optical label case as the light emitting direction. The front shell 302 and the rear shell 303 may be two separable parts, but may also be two parts or two areas of the same part. In fig. 3, the transparent portion 304 is arranged at an upper edge of the housing of the optical label, but it will be appreciated that the transparent portion may also be arranged elsewhere, or at the entire edge of the housing of the optical label. The projection light source 301 is arranged inside the optical label housing and is configured to emit light towards the transparent portion 304 of the optical label housing so as to be able to illuminate the transparent portion 304. The projection light source 304 may be, for example, an LED lamp.
The optical label shown in fig. 3 also has a mounting bracket 306 and mounting screws 305. The optical label may be mounted to a surface, such as a wall surface, via mounting brackets 306 and mounting screws 305. It will be appreciated by those skilled in the art that any other feasible means (e.g., adhesive, snap) may be used to mount the optical label.
Fig. 4 illustrates an exploded view of a projected optical label according to one embodiment of the present application. From this exploded view, the positional relationship among the projection light source 301, the front case 302, the rear case 303, and the transparent portion 304 of the optical label can be more clearly understood.
By making the projection light source 301 emit light after the optical label is mounted on, for example, a wall surface, a corresponding projection pattern can be presented on the wall surface via the transparent portion 304, which can be easily found by human eyes in an environment where light is insufficient. Further, depending on the distance and angle of the projection light source 301 from the transparent portion 304, the distance of the optical label from the wall on which it is mounted, etc., the size of the projection pattern may even be larger or even much larger than the size of the optical label itself, thereby facilitating easy discovery of the optical label in the field of view by the user.
FIG. 5 illustrates an exemplary projected pattern presented using a projected optical label according to one embodiment of the present application on a mounting surface located on a rear side of the projected optical label. The shaded portion of the projection pattern shown in fig. 5 indicates a portion that cannot be illuminated by the projection light source 301 due to the shielding of the rear case 303, and outside the shaded portion, is a portion that is illuminated by the light emitted by the projection light source 301 through the transparent portion 304.
In some embodiments, a cutout may be employed in place of a transparent portion in the optical label housing, and the transparent portion or cutout in the optical label housing may be located at any suitable location on the back side and/or edge of the optical label housing, so long as at least a portion of the generated projected pattern is not obscured by the optical label.
In one embodiment, a hollowed-out or transparent pattern, such as a ring pattern, may be provided on the back side of the optical label housing, and a projection light source may be provided near the center of the ring. When the projection light source is started, the projection light source can project a bright circular ring on the surface of the wall where the optical label is installed through the hollowed or transparent circular ring pattern. FIG. 6 illustrates an exemplary annular projection pattern presented using a projected optical label according to one embodiment of the present application, where the shaded portions represent portions not illuminated by the projection light source and the annular portions represent portions illuminated by the projection light source.
In the optical label shown in fig. 3, there is one projection light source, but in other embodiments, the optical label may have two or more projection light sources, which may be arranged at different locations within the optical label housing to achieve more complex projection patterns. For example, for a hollowed-out or transparent ring pattern disposed on the rear side of the optical label housing, if two projection light sources are used, a projection pattern having two intersecting rings can be presented.
In one embodiment, the controller may be configured to control the projection light source to blink, for example, at a certain frequency (e.g., 1 Hz). The blinking may be, for example, blinking that is achieved by controlling the projection light source to be turned on and off, or blinking that is achieved by controlling the projection light source to alternately emit light of different colors (e.g., controlling the projection light source to alternately emit blue light and red light). In this way, the user can be made to find the light label in his field of view more easily, since a dynamically blinking pattern is more easily perceived by the human eye than a static pattern.
In one embodiment, the projection optical label may further include one or more light sensitive elements located on the front side of the optical label. The photosensitive element is used for sensing the ambient light of the environment where the optical label is located, so that the optical label can automatically adjust the intensity and/or wavelength of the light emitted by the projection light source and/or the data light source according to the intensity and/or wavelength of the ambient light and the like, thereby being convenient for the human eye to find the optical label and being convenient for the equipment to identify the optical label, and being also helpful for realizing energy saving in some cases. For example, if the photosensitive element detects strong ambient light, the controller in the optical tag or a controller coupled to the optical tag may increase the intensity of the light emitted by the projection light source and/or the data light source of the optical tag according to the detection result to better distinguish from the ambient light; on the contrary, if the photosensitive element detects weak ambient light, the controller in the optical tag or the controller coupled to the optical tag may reduce the intensity of light emitted by the projection light source and/or the data light source of the optical tag according to the detection result, so as to save electric energy consumed by the optical tag as much as possible on the premise of being distinguishable from the ambient light, and avoid the optical tag emitting too strong light that may stimulate human eyes.
In one embodiment, the optical label may include one or more light sensitive elements located on a back side of the optical label. The light sensor on the rear side of the optical label is used for sensing the ambient light from the rear side of the optical label, so that the optical label can automatically adjust the intensity and/or wavelength of the light emitted by the projection light source and/or the data light source of the optical label according to the intensity and/or wavelength and the like of the ambient light on the rear side of the optical label, and discovery and identification of the optical label are facilitated. For example, if a light sensitive element located on the rear side of the optical label detects that the surface on which the optical label is mounted is red, a controller in the optical label or a controller coupled to the optical label may set the projection light source and/or the data light source of the optical label to emit light of another color according to the detection result, thereby improving the discovery and identification of the optical label.
In one embodiment, the projection light source may be activated when insufficient ambient light is detected by the light sensitive element (e.g., the ambient light intensity is below some predetermined threshold), and deactivated when the ambient light is sufficient.
In one embodiment, the rear side of the projection optical label (i.e., the side facing the surface on which the optical label is mounted) has an adjustable mounting mechanism by which the distance of the projection optical label from the surface on which it is mounted can be adjusted, thereby adjusting the size and brightness of the projected pattern of the projection optical label on the surface on which it is mounted. Generally, a longer distance corresponds to a larger projected pattern and lower brightness. For example, the mounting bracket 306 or mounting screw 305 of the optical tag shown in FIG. 3 may be adjustable, by which the distance of the projected optical tag from the surface on which it is mounted may be adjusted.
So, through the utility model discloses a scheme has realized a projection formula optical label who possesses projection function, and it can demonstrate specific projection pattern to easily by user discovery, be convenient for realize user and optical label's good interaction, improved user's use and experienced. The utility model discloses a projection formula optical label specially adapted light not enough environment.
