1. Field of the Invention
The present invention is related to a projection alarm clock, and more particularly to a multimedia projection alarm clock with integrated illumination.
2. Description of the Prior Art
In general, a projection clock projects a clock image, dial or digital, on a surface such as a ceiling or a wall. Since the clock image, usually enlarged, can be viewed in the dark, a projection clock serves as a convenient bedside companion.
Conventionally, a projection clock projects an image of an actual mechanical dial clock or a digital clock constructed with 7-segment displays. In order to serve the purpose to be a bedside companion, a projection clock usually includes an alarm feature, which is appealing to be delightful and entertaining. However, conventional mechanisms for creating clock images do not allow much variation to be introduced to the alarm feature of the projection clock.
Besides a projection clock, a night light is usually required for bedside. Conventionally, the projection clock and night light are separate entities and as a result, a user usually has to identify the two in the dark.
Therefore, it is highly desirable to provide a multimedia projection alarm clock with integrated illumination as an ultimate bedside companion that uses a simple user interface for all the handy functions and provides a dynamically entertaining alarm feature.

FIG. 1 is a block diagram illustrating the multimedia projection alarm clock with integrated illumination 100 according to an embodiment of the present invention. As shown in FIG. 1, the multimedia projection alarm clock with integrated illumination 100 includes: a projector module 130 for projecting an animated image and an information on a surface; an illuminating light source 150 for emitting an illuminating light with adjustable color and/or brightness; a speaker 170 for outputting music or sound effects; a control unit 110 electrically connected with the projector module 130, the illuminating light source 150 and the speaker 170 so as to generate an alarm signal comprising the animated image, the music or sound effects, the illuminating light or combinations thereof when reaching a preset alarm time; a user interface 190 for a user to operate the multimedia projection alarm clock with integrated illumination 100; and a power supply module 210 for supplying power needed for the operations of the multimedia projection alarm clock with integrated illumination 100.
In the above-mentioned embodiment, the projector module 130 is controlled by the control unit 110, which may be a microprocessor control unit (MCU), so that it is possible to project an animated image such as a moving figure or object as the alarm signal. Not only so, the control unit 110 may also play music or sound effects with the animated image so that a vivid figure such as a vocalizing animal or a noisy vehicle such as an approaching UFO may be created. Besides, since the multimedia projection alarm clock with integrated illumination 100 of the above-mentioned embodiment is equipped with the illuminating light source 150 that is also under the control of the control unit 110, light effects may be added. A theme of the alarm signal may, therefore, be composed with the coordinated animated image, music or sound effects and illuminating light.
FIG. 2-1 and FIG. 2-2 are schematic diagrams illustrating the alarm signal of the multimedia projection alarm clock with integrated illumination according to an embodiment. In this embodiment, a theme of a person dancing happily with music is presented, wherein the alarm signal includes an animated image 142 of a dancing person who dances with the music 172 of brisk tempo, and the illuminating light 152 that varies the flashing frequency and/or color with the tempo of the music 172.
FIG. 3-1 and FIG. 3-2 are schematic diagrams illustrating the alarm signal of the multimedia projection alarm clock with integrated illumination 100 according to another embodiment. In this embodiment, a theme of a lively farm morning is presented, wherein the alarm signal includes an animated image 142 of a cock with a moving head and mouth, sound effects 172 of the cock-a-doodle-doo sound played when the cock raises its head and opens its mouth, and a white illuminating light 152 that lights up at least a portion of the room to signify the arrival of a bright day.
According to another embodiment, a theme of an approaching UFO that greets the user is presented, wherein the alarm signal starts with an illuminating light 152 that varies its color and intensity, and sound effects 172 of a high frequency and yet far away noise resembling that emitted by a far away UFO. When the user is awoke and disable the alarm signal, the animated image 142 shows an approaching UFO (a gradually enlarging object), and sound effects 172 mimicking the Doppler effect of an approaching UFO. When the animated image 142 stops moving, a greeting sound effect 172 saying, for example, “Good Morning!” may be played.
According to an embodiment, the control unit also controls the animated image 142, the music or sound effects 172 and the illuminating light 152 independently so that each function may be accessed separately, or as a group such as in the form of a bed mode, in which the illuminating light 152 changes its color slowly with the music 172 to provide a soothing effect for the user before bed.
In the following, embodiments with further details of the components or additional features of the multimedia projection alarm clock with integrated illumination are disclosed.
Referring to FIG. 1, the projector module 130, according to an embodiment, comprises a transmissive type image panel 134 for displaying the animated image and the information; a projecting light source 132 configured on one side of the image panel 134 so as to emit a projecting light 138 to pass through the image panel 134 to produce a projected image on a surface such as a wall; and a set of projecting lenses 136 configured on the optical path of the projected image on the other side of the image panel 134 so as to focus or adjust the size of the projected image.
According to another embodiment, the projector module comprises a reflective type image panel for displaying the animated image and the information; a projecting light source emitting a projecting light to be reflected by the image panel to produce a projected image on a surface such as a wall; and a set of projecting lenses configured on the optical path of the projected image so as to focus or adjust the size of the projected image. The configuration of the above embodiments for the projector module may be modified with additional optical elements such as prisms or mirrors as one skilled in the art may understand.
The image panel, as indicated above, may be transmissive type or reflective type. The transmissive type image panel can be but not limited to a liquid crystal display (LCD) panel. The reflective type image panel can be but not limited to a Liquid Crystal on Silicon (LCoS) panel.

Referring to FIG. 1, the pattern that the image panel 134 displays may include information such as time, week, date, and so on, and an animated image as described above. The resolution of the image panel 134 should be sufficient to differentiate numbers and portray the shape of figures or objects, e.g. around 96×64 dots. The size of the image panel 134, according to one embodiment, can be fairly small, e.g. around 1 inch; as a result, it is possible to pack the projector module into a compact shape such as the pyramid in FIG. 2-1, and the flower bud in FIG. 3-1, an advantage which the prior art projection clocks are unlikely to have, since an actual mechanical clock or digital clock are required to be positioned. According to different embodiments, the angle at which the projector module 130 projects the image may be fixed as shown in FIG. 2-1, or variable as shown in FIG. 3-1, where the stem of the flower is bendable.
Referring to FIG. 1, the projecting light source 132 is strong enough to project the patterns on the image panel 134 onto the wall clearly. Also, the image not only may be viewed in the dark like during the night time, but also may be seen with light such as in the day time. According to different embodiments, the projecting light source can be but not limited to including high power white light emitting diodes (LED), halogen light bulbs, HID (High Intensity Discharge) light bulbs or UHP (Ultra High Performance) light bulbs or the combinations thereof.
Referring to FIG. 1, the illuminating light source 150, according to one embodiment, can be but not limited to including red, green and blue light emitting diodes (RGB LEDs) and/or white LEDs, so that the illuminating light 152 of adjustable color and/or brightness may be provided.
Referring to FIG. 1, the user interface 190 is connected with the control unit 110, allowing the user to set the settings such as time, week, date, alarm time, alarm signal etc., and to disable the alarm signal. The user interface 190 may also allow the user to, separately or as a group, turn on/off the projector module 130, the speaker 170 and the illuminating light source 150, and/or select the animated image 142, the music or sound effects 172, the color or brightness of the illuminating light 152.
The user interface 190, according to an embodiment, includes a key set on the housing of the multimedia projection alarm clock with integrated illumination 100. The key set may be touch-sensing, such as a capacitive touch-sensing key set. According to an embodiment, the user interface may also include, on the housing of the multimedia projection alarm clock with integrated illumination 100 such as at the top of the flower pot in FIG. 3-1, a touch-sensing switch, e.g. a capacitive touch-sensing switch, for the illuminating light source 150, so that the multimedia projection alarm clock with integrated illumination 100 may also be used as a night light or lamp. The clock image may also be projected together if desired, and the alarm signal may be disabled in the same manner, i.e. by slightly tapping the surface at the top of the flower pot shown in FIG. 3-1.
FIG. 4 is a block diagram illustrating the multimedia projection alarm clock with integrated illumination 100 with another embodiment of the user interface 190. The user interface 190 here includes a remote control on which a key set is disposed. The key set may be touch-sensing. With the remote control, the size of the multimedia projection alarm clock can be more compact, and the user does not have to turn back and forth between the multimedia projection alarm clock with integrated illumination 100 and the projected image to adjust the settings.
