The first connection part 122 and the second connection part 123 are pivoted on two opposite ends of the rod 121 respectively so that they can rotate clockwise or counterclockwise around a first direction parallel to a central axis of the rod 121. Moreover, the lamp shade 110 and the base 130 are pivoted on the first connection part 122 and the second connection part 123 of the support arm 120 so as to be turned around a second direction perpendicular to the first direction respectively. In this way, the relative distance and the included angle between the lamp shade 110 and the base 130 may be adjusted.
The base 130 includes a casing 131 and a chassis 132. The casing 131 is pivotally connected to the first connection part of the support arm 120 and covers the chassis 132 to define an accommodating space 133 in which the input/output circuit board 140, the light control circuit board 150, the optical disk drive 160, the ballast 170, the speaker 180 and the modulation knob 190 are disposed. In addition, on the casing 131 is formed at least one through hole 1311, an opening 1312 and a speaker hole 131 all through to the accommodating space 133. The speaker hole 131 is located on the top of the casing 131; the through holes 1311 and the opening 1312 are respectively located on the side surface of the casing 131. A pressing part 1314 is formed on the top of the casing 131.
On the input/output circuit board 140 are electrically disposed a micro-controller unit (MCU) and one or more electric connectors such as a power connector 141, a universal serial bus (USB) connector 142, an audio input/output interface 143, a card reader connector 144 or a combination thereof. In the present embodiment, the power connector 141 is located on the casing 131 of the base 130 and is further electrically connected to the input/output circuit board 140 through an electric cable, while the USB connector 142, the audio input/output interface 143 and the card reader connector 144 are electrically inserted onto the input/output circuit board 140. It is noted that the aforementioned description is exemplified for illustration only; it should not be considered as a limitation to the present invention. In another embodiment of this invention, the power connector 141 can be independent of the input/output circuit board 140 in the casing 131 of the base 130. In this embodiment, preferably, the power connector 141 is electrically connected to a power shunt through a power line, and the input/output circuit board 140 and the light control circuit board 150 are powered by way of the power shunt.
Besides, in the first embodiment of the present invention, the input/output circuit board 140 can be fastened to the casing 131 by a fastener such as a screw and/or bolt for example. Furthermore, the aforementioned electric connector are positioned corresponding to and passes through the through hole 1311 of the casing 131 to thereby be exposed in part from the base 130. Hence, a person of ordinary skill in the art will appreciate that the number of the through hole 1311 formed on the casing 131 can be determined by the number of the electric connector located on the input/output circuit board 140.
The light control circuit board 150 is electrically connected to the input/output circuit board 140 and the illuminating unit 111 and serves as a power switch in connection with the pressing part 1314 for modulating the light emission of the illuminating unit 111. Although in this embodiment, the touch switch is realized by the light control circuit board 150 cooperating with the pressing part 1314 of the casing 131, the present invention is not limited thereto.
The optical disk drive 160, the speaker 180 and the modulation knob 190 are respectively connected with the input/output circuit board 140, in which the optical disk drive 160 is partially exposed from the opening 1312 of the casing 131 so that the disk tray of the optical disk drive 160 can be ejected through the opening 1312 of the casing 131 outside the base 130 or retrieved inside the base 130. The speaker 180 can be, but not limited to, a horn or a microphone; in addition, the speaker 180 and the modulation knob 190 are positioned respectively corresponding to the speaker hole 1313 and one through hole 1311 of the casing 131, in which the modulation knob 190 is totally or partially exposed from the base 130 via the through hole 1311 and is used to modulate the volume of the speaker 180. In particular, when the speaker 180 is a horn, it can work as a mobile speaker of a portable electronic device. If a decoder is electrically provided on the input/output circuit board 140 for reading and playing audio files in a computer or an external storage device (e.g. a storage card or a flash disk).
The ballast 170 is disposed between the chassis 132 of the base 132 and the optical disk drive 160 to lower the gravity center of the digital table lamp 10 and provide protection for the aforementioned components inside the base 130.
As shown in FIGS. 1-3, based on the aforementioned structure, the power connector 141 of the input/output circuit board 140 can be connected to an external power supply via the through hole 1311 of the base 130 by a power cable, thus allowing the digital table lamp 10 to be powered externally. Besides, when the digital table lamp is placed on a working bench such as an office desk or a studying desk, an electric wire can be connected with the USB connector 142 of the input/output circuit board 140 to form a connection with a computer under the working bench. Accordingly, the digital table lamp 10 can be regarded as a computer peripheral by way of the USB connector 142, the audio input/output interface 143 and the card reader connector 144 provided by the digital table lamp 10. For instance, the user can treat the USB connector 142, the audio input/output interface 143 and/or the card reader connector 144 may serve as a hub port, an audio transmission interface and/or a card reader.
As a result, the present invention allows a user to connect an electronic device such as a portable hard disk, a keyboard or a mouse to the digital table lamp 10 on the working bench without stooping for a socket of the computer under the working bench. Additionally, the user can access the computer through the digital table lamp 10 or operate the optical disk drive 160 on the working bench easily and conveniently. Moreover, regarding an electronic device such as a notebook computer or a tablet computer having no optical disk drive, the optical disk drive 160 connected with the digital table lamp 10 can serve as an external optical disk drive for the electronic device, which is helpful in improving the convenience.
Referring to FIG. 4 illustrating the second embodiment of the present invention, a digital table lamp 10 includes a lamp shade 110, a support arm 120, a base 130, an input/output circuit board 140, a light control circuit board 150 and an optical disk drive electrically connected to the input/output circuit board 140.
The support arm 120 includes a rod 121, a first connection part 122 and a second connection part 123. The first connection part 122 and the second connection part 123 are pivoted on the opposite two ends of the rod 121 respectively and can rotate clockwise or counterclockwise around a first direction parallel to a central axis of the rod 121. Moreover, the lamp shade 110 and the base 130 are pivoted on the first connection part 122 and the second connection part 123 of the support arm 120 respectively and can rotate around a second direction perpendicular to the first direction to allow an adjustment of the relative distance and included angle between the lamp shade 110 and the base 130. In addition, the lamp shade 110 has an illuminating unit 111 therein, that can be, but not limited to a fluorescent lamp or an LED lamp.
The base 130 includes a casing 131 and a chassis 132 and an accommodating space 133 is defined therebetween. The casing 131 is pivoted on the first connection part 121 of the support arm 120 and covers the chassis 132. A plurality of through holes 1311 and an opening 1312 through to the accommodating space 133 are formed on the casing 131 of the base 130 together with a pressing part (not shown)
The input/output circuit board 140, the light control circuit board 150 and the optical disk drive 160 are located in the accommodating space 133 of the base 130. The input/output circuit board 140 is electrically connected to the power connector 141 of the casing 131 of the base 130; meanwhile, a micro-controller unit (MCU) and a USB connector 142 are electrically disposed on the input/output circuit board 140. When the input/output circuit board 140 are fastened to the casing 131, the power connector 141 and the USB connector 142 are positioned corresponding to the through holes 1311 of the casing 131 to be partially exposed from the base 130.

The light control circuit board 150 and the pressing part 1314 of the casing 131 constitute a power switch for triggering the light generation from the illuminating unit 111. A user pushes the pressing part 1314 to connect with the light control circuit board 150 and further trigger the illuminating unit 111 to emit light. For instance, when the pressing part 1314 of the casing 131 is touched for the first time, the light control circuit board 150 is conductive and the illuminating unit 111 emits light. The light intensity may be increased in proportion to the number of the pressing. In case the pressing part 1314 of the casing 131 is pressed for a longer time, the illuminating unit 111 is stopped from being powered.
The optical disk drive 160 located between the chassis 132 of the base 130 and the input/output circuit board 140, and partially exposed from the opening 1312 of the casing 131 so that the disk tray of the optical disk drive 160 can be ejected or retrieved through the opening 1312 of the casing 131.
Besides, in the first and second embodiments of the present invention, a non-skid pad can be optionally provided on the base 130 of the digital table lamp 10 for improving the stability of the digital table lamp 10 when placed on a working bench.
In view of the above, the digital table lamp of the present invention is advantageous since it can function as a lighting apparatus and a computer peripheral. Thus, the space can be spared for other computer peripherals such as a card reader, an outer optical disk drive or a hub port, and the available space on the working bench is relatively increased.
Moreover, an external electronic device can be connected further with the computer under the working bench through the digital table lamp. A user can also operate the optical disk drive of the digital table lamp on the working bench in a convenient way.
The aforementioned descriptions represent merely the preferred embodiment of the present invention, without any intention to limit the scope of the present invention thereto.
