Description

COMPOSITE STRUCTURE FOR POLYGONAL LIGHT-EMITTING
DIODE
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention provides a polygonal LED (light-emitting diode), and more particularly provides a composite structure for polygonal LED which enables multivaried assembly of a plurality of polygonal LED modules, providing high expansionability and high variability, and further achieving saving in time and cost.
(b) Description of the Prior Art
Because the light-emitting diode (LED) is a solid-state semiconductor element, thus, interoperability of electron holes is used to release energy in light form, and belongs to luminescence. Moreover, advantages of the LED include small size, fast response speed, long serviceable life, low power consumption, superior shock resistance and non-polluting. Light-emitting elements are presently already widely utilized in many areas, including electric appliances, information billboards, communication products, and the like, in particular, current lighting equipment which use light-emitting diodes as light-emitting elements. Although the efficiency of the first light-emitting diodes was lower than anticipated compared with traditional lighting equipment, however, subsequent improvements in technology and material have brought about substantial progress in the luminance brightness of light-emitting diodes currently manufactured, which has affected the gradual replacement of traditional light-emitting elements.
Manufacturing processes of LED modules of the prior art involve first separately encapsulating the LED5 to form LED encapsulated structures, after which the electrodes of the LED5 are welded to a baseplate using surface mounting technology (SMT) to form electrical circuits, thereby producing the LED module, in which the baseplate is normally a printed circuit board (PCB).
However, expansion of such LED modules cannot be carried out, and, after fixedly welding, connective expansion of most of such LED modules cannot be increased. Hence, the LED modules must be completely replaced when a user wants to increase the number of LED modules, which places enormous demands on cost, thus, insufficient expansionability increases cost, as well as requiring time to replace the LED modules. Thus, there are a multitude of reasons preventing advancement in industrial competitiveness.
Moreover, one module among the set of LED modules cannot be singularly replaced if there is a fault or operating efficiency is poor in the one module, and the entire set of modules must be replaced. Thus, such LED modules are extremely ineffective with respect to cost and time.
Hence, it is the strong desire of the inventor and manufacturers engaged in related art and purpose of the present invention to research, improve and resolve the problems and shortcomings of the
aforementioned prior art.
SUMMARY OF THE INVENTION
Hence, in light of the shortcomings of the aforementioned prior art, the inventor of the present invention, having collected related data, and through evaluation and consideration from many aspects, as well as having accumulated years of experience in related arts, through continuous testing and improvements, has designed a new composite structure for polygonal LED (light-emitting diode) as disclosed in the present invention which enables multivaried assembly of a plurality of polygonal LED modules, providing high expansionability and high variability, and further achieving saving in time and cost.
The primary objective of the present invention lies in the composite structure comprising a transformer and a LED module assembly, in which the transformer is electrically connected to the LED module assembly to enable controlling the LED module assembly, and the LED module assembly is structurally assembled from a plurality of polygonal LED modules. The lengths of sides of the LED modules enable corresponding combination thereof, thereby enabling the LED modules to be mutually connected together from any one of the sides.
Accordingly, when a user wants to expand the LED modules, then the sides of the LED module are used to mutually connect to the sides of another of the LED modules. Connecting means can use screw tightening, solder joining, insertion fastening, drive fitting or adhesive affixing to fixedly connect the LED modules together. According to the art described above, the present invention provides a breakthrough in solving the existing problems of advancement in industrial competitiveness because of a multitude of reasons, including the inability to carry out expansion of LED modules of the prior art, and, after fixedly welding, connective expansion of most of such LED modules cannot be increased, thus, requiring the LED modules to be completely replaced when a user wants to increase the number of LED modules, thereby placing enormous demands on cost, and increasing cost because of insufficient expansionability, as well as requiring time to replace the LED modules; moreover, one module among the set of LED modules cannot be singularly replaced if there is a fault or operating efficiency is poor in the one module, and the entire set of modules must be replaced; hence, such LED modules of the prior art are extremely ineffective with respect to cost and time. The present invention achieves the breakthrough by using the lengths of the sides of the LED modules to enable corresponding combination thereof, thereby enabling the LED modules to be mutually connected together from any one of the sides.
Hence, the user is able to carry out assembly or fixedly joining together of the LED modules according to needs or preference, thereby achieving advancement in a LED module assembly providing high expansionability, high luminance, superior area light source, low cost and the ability to be controlled using one transformer.
