This application claims the priority benefit of Taiwan application serial no. 99133377, filed Sep. 30, 2010. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
1. Field of the Invention
The invention relates to a lamp and more particularly to a light emitting diode (LED) lamp.
2. Description of Related Art
Light emitting diodes (LEDs) are semiconductor devices. Light emitting chips are mainly fabricated using compounds of group III-V elements, for example, gallium phosphide (GaP) or gallium arsenide (GaAs). Moreover, LEDs emit light by converting electric energy into light energy. In details, LEDs apply currents to compound semiconductors so as to release excess energy in the form of light through the binding of electrons and holes. Since illumination of LEDs does not result from heating or discharging, the lifespan of LEDs could be longer than one hundred thousand hours. LEDs further include advantages such as fast responding speed, small volume, energy saving, low pollution, high reliability, suitable for mass production, and so on. Thus, LEDs could be widely applied in various fields, for instance, large display boards, traffic lights, cellular phones, scanners, light sources of fax machines, flat lamps and the like.
As for flat lamps, currently, the installation of a flat lamp requires screwing the base to a wall and then installing the flat lamp to the base, or screwing a lamp board directly on a wall. These installations consume more time and labor and it is unable to install when lack of installation components occur. In Taiwan Patent No. TWM386437, a lighting device adopting a magnet disposed thereon for adhering to a metal surface is disclosed. A side-lighting illumination device having a magnetic connector is disclosed in U.S. Pat. No. 7,766,502.
The invention is directed to a light emitting diode lamp with simple installation.
The advantages of the invention are further illustrated from the technical characteristics disclosed in the invention.
One of the embodiments of the invention provides an LED lamp to achieve one or a part of or all of the objectives above-mentioned or other objectives. The LED lamp includes a back plate, at least one cover, a light guide plate, at least one magnetic element, and an LED light source. The cover is fixed to the back plate. The light guide plate is disposed on the back plate and a part of the light guide plate is sandwiched between the back plate and the at least one cover. The at least one magnetic element is disposed on the back plate and sandwiched between the back plate and the at least one cover. The light emitting diode light source is disposed at a side of the light guide plate.
In light of the foregoing, the embodiment aforementioned has at least one following advantage. The LED lamp is fixed to the surface through the magnetic element without screwing so that the installation and un-installation of the lamp become more convenient. In addition, the cover configured to fix the magnetic element also functions to fix the light guide board, such that the entire structure is more stable and the assembly of the components could be simplified.
Other objectives, features and advantages of the invention will be further understood from the further technological features disclosed by the embodiments of the present invention wherein there are shown and described preferred embodiments of this invention, simply by way of illustration of modes best suited to carry out the invention.
The accompanying drawings are included to provide further understanding, and are incorporated in and constitute a part of this specification. The drawings illustrate exemplary embodiments and, together with the description, serve to explain the principles of the disclosure.
In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part hereof, and in which are shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology, such as “top,” “bottom,” “front,” “back,” etc., is used with reference to the orientation of the Figure(s) being described. The components of the present invention can be positioned in a number of different orientations. As such, the directional terminology is used for purposes of illustration and is in no way limiting. On the other hand, the drawings are only schematic and the sizes of components may be exaggerated for clarity. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention. Also, it is to be understood that the phraseology and terminology used herein are for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Unless limited otherwise, the terms “connected,” “coupled,” and “mounted” and variations thereof herein are used broadly and encompass direct and indirect connections, couplings, and mountings. Similarly, the terms “facing,” “faces” and variations thereof herein are used broadly and encompass direct and indirect facing, and “adjacent to” and variations thereof herein are used broadly and encompass directly and indirectly “adjacent to”. Therefore, the description of “A” component facing “B” component herein may contain the situations that “A” component directly faces “B” component or one or more additional components are between “A” component and “B” component. Also, the description of “A” component “adjacent to” “B” component herein may contain the situations that “A” component is directly “adjacent to” “B” component or one or more additional components are between “A” component and “B” component. Accordingly, the drawings and descriptions will be regarded as illustrative in nature and not as restrictive.
As shown in
Referring to
In summary, the embodiment or the embodiments aforementioned may have at least one following advantage. The LED lamp is fixed to the surface through the magnetic element without screwing, so that the installation and un-installation of the lamp become more convenient. In addition, the cover configured to fix the magnetic element also functions to fix the light guide board, such that the entire structure is more stable and the assembly of the components could be simplified. Furthermore, a power outlet configured to connect a power device could be disposed between the cover and the back plate, so that the LED lamp and the power device are separable to each other and thus more convenient of carrying and packaging.
The foregoing description of the preferred embodiments of the invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form or to exemplary embodiments disclosed. Accordingly, the foregoing description should be regarded as illustrative rather than restrictive. Obviously, many modifications and variations will be apparent to practitioners skilled in this art. The embodiments are chosen and described in order to best explain the principles of the invention and its best mode practical application, thereby to enable persons skilled in the art to understand the invention for various embodiments and with various modifications as are suited to the particular use or implementation contemplated.
