      (a) Field of the Invention  
      The present invention is related to an art of upgrading the illumination of a light emitting diode for providing a construction of the light emitting diode with the effects of high illumination performance.  
      (b) Description of the Prior Art:  
      Light emitting diode characterized by smaller size, lower power consumption, lower heat and longer service life has been gradually replaced the conventional tungsten lamp bulb of similar functions applied in Christmas decorative string lamps, signal lights on vehicles, traffic signs and other commodities. The light emitting diode is essentially comprised of a transparent insulator containing multiple conducting ends of different polarities and a carrier, a chip is fixed to the carrier, fluorescent material is applied to the peripheral of the chip, a gold plated wire connects the electrode of the chip and those conducting ends, and each conducting end extends through the transparent insulator to become a power source contact. When the conducting ends are conducted, the light generated from the chip emits through the fluorescent material and to become the visible light as expected by incorporating the wavelength of the fluorescent material. Therefore, given with the improved manufacturing process and technology, the light emitting diode may become a light-emitting device with performance of specific light color through the design of the fluorescent material to fast expand the application range of the light emitting diode.  
      However, the existing R&amp;D efforts on the light emitting diode focuses on the effects of the light color performance and promotion of the production capacity. Less attention is paid on how to increase the illumination of the light emitting diode.  
     SUMMARY OF THE INVENTION  
      The primary purpose of the present invention is to provide a high illumination light emitting diode to increase the illumination of the light emitting diode.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
      Referring to  FIG. 1  for the basic configuration of a light emitting diode of a first preferred embodiment of the present invention, a transparent insulator  10  contains multiple conducting ends  20  of different polarities and a carrier  30 ; a chip  40  is fixed to the carrier and a fluorescent material  60  is applied to the peripheral of the chip  40 ; a gold plated wire  50  connects an electrode  41  of the chip and those conducting ends  20 ; and each conducting end  20  extends through the transparent insulator  10  to become a power source contact. Accordingly, when the conducting ends  20  are conducted, the light emitted from the chip  40  has its wavelength incorporated with that from the fluorescence  60  as it passes through it to become visible light as expected.  
      As illustrated in  FIG. 2 , a reflector  70  is further fixed to the carrier  30  on the side adapted with the chip  40 . The carrier  30  is made in a bowl shape provided on one of those conducting end  20 , and the reflector  70  relates to a glass mirror adhered at where between the chip and the bottom of the carrier  30 . The fluorescent material  60  comprised of admixture of the adhesive material that bonds the chip  40  and the fluorescent material is adapted at where between the chip  40  and the reflector  70  so to adhere the chip  40  to the upper part of the reflector. The light emitted from the light source of the chip  40  is reflected by the reflector to project to the exterior of the transparent insulator  10  to effectively increase the illumination of the light emitting diode.  
      Furthermore, the type of the fluorescent material may vary depending on the spatial configuration and manufacturing process of the light emitting diode; and the reflector may be present in the form of mirror layer, glass mirror, metal plated layer, or baking varnished metal.  
      The light emitting diode of the first preferred embodiment of the present invention as illustrated in  FIG. 1  is completed with two times of baking during the manufacturing process. Wherein, the chip  40 , the reflector  70  and the carrier are combined in the baking process; the surface of the chip  40  is coated with a course of transparent glue  80  while having the gold plated wire  50  to connect the electrode  41  and those conducting ends before the diode is put into the baking process once again. The finished diode has the transparent insulation glue  80  formed on the surface of the chip  40 .  
      A construction of the diode of a second preferred embodiment of the present invention is completed with a single baking process as illustrated in  FIG. 3 . Wherein, reflector  70  all over the inside are of the bowl carrier  30 ; the chip  40  is directly placed on the reflector  70 ; the gold plated wire  50  connects the electrode  41  of the chip  40  and those conducting ends  20 ; and the carrier  30  is filled up with the fluorescent material  60  comprised of the transparent insulation glue and fluorescent powder. Finally, the diode is hardened in the second baking process. During the baking process, the fluorescent powder consistently covered up on the surface of the chip due to the central gravity and the transparent glue in the entire fluorescent material  60  turns into a clear light permeable construction.  
      A third preferred embodiment of the present invention as illustrated in  FIG. 4  has the diode directly provided on a circuit board  90 . Multiple pits are preset on the circuit board  90  to each define the carrier  30 ; the reflector is fixed on the bottom inside the carrier  30 ; and each conducting end (not illustrated) is directly arranged on the circuit contact of the circuit board  90 .  
      The present invention provides the art to effectively increase the illumination of the light emitting diode and this application for a patent is duly filed accordingly. However, that it is to be noted that the preferred embodiments and the accompanying drawings disclosed in the specification do not in any way restrict the present invention and that any structure, device and characteristics that are similar, or identical with those of the present invention shall be deemed as falling within the objective and the claims of the present invention.
