1. Field of the Invention
The present invention relates to display apparatus, and particularly to a monitor having illuminating function.
2. Description of Related Art
Flat panel displays are more and more popularly used in offices. The relative lightness and compactness of flat panel displays (particularly in terms of front to back depth) make them particularly suitable for narrow workspaces. The characteristics of flat panel displays are particularly attractive in a small office/home office setting, because the relatively shallow front to back depth means that the display can be pushed back further from a user than would be possible with an equivalent cathode ray tube (CRT) monitor in many situations, taking up less precious desktop space in a user's work area. Additionally, falling prices of flat panel displays over the last several years, make them even more attractive to SOHO entrepreneurs.
Typically, other office equipment, such as desk lamps, telephones, printers, and so on, take up premium space on a desktop, to the point of being intrusive or at least inconvenient, adversely affecting work mood and efficiency in a SOHO. Though flat panel displays are increasingly selected for use in offices, desktop space is still at a premium, so desk lamps can particularly exacerbate the problem.
An exemplary display apparatus comprising a monitor having a frame and a built-in power transforming module; a support module having a terminal mounted on the frame of the monitor and another terminal; a luminescence module mounted on the another terminal of the support module, having an anode power cord and a cathode power cord coupled to the power transforming module; and a switch connected to the power transforming module to turn on/off the power transforming module.
Other advantages and novel features will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:
Referring to
In this embodiment, the power transforming module 20 includes a transformer U1, three resistors R1˜R3, an inductance L, and a Schottky diode D8. The transformer U1 includes an input pin VIN, an output pin SW, a feedback pin FB, a ground pin GND, and a control pin
When the switch 30 is opened, the power transforming module 20 is turned off. When the switch 30 is closed, the power transforming module 20 is turned on, and the transformer U1 outputs 36 volts via the output pin SW to drive the luminescence module.
Referring to
The foregoing description of the exemplary embodiments of the invention has been presented only for the purposes of illustration and description and is not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to explain the principles of the invention and their practical application so as to enable others skilled in the art to utilize the invention and various embodiments and with various modifications as are suited to the particular use contemplated. Alternative embodiments will become apparent to those skilled in the art to which the present invention pertains without departing from its spirit and scope. Accordingly, the scope of the present invention is defined by the appended claims rather than the foregoing description and the exemplary embodiments described therein.
