Title: Led illumination apparatus for spot lighting

Description:
FIELD OF THE INVENTION 
     The present invention relates to an LED illumination apparatus for spot lighting, and in particular to an LED lamp capable of increasing the brightness of the LED illumination. 
     DESCRIPTION OF THE RELATED ART 
     Since light emitting diodes (LEDs) feature the high brightness, power saving and long life expectancy advantages, they have been used extensively for the illumination of lamps. Several LED lamps are usually connected to form an LED lamp set, and the position of each lamp can be adjusted to achieve an illumination effect to meet the requirements for a large projecting area and a high brightness. These LED lamp sets are used as illuminating devices indoors and outdoors. However, it is necessary to plan the LED lamps and the layout of different projecting areas, so as to differentiate the projecting area for each LED lamp with a different distance from the LED lamp and the projecting area, and prevent an uneven brightness of the light projected front the LED lamps onto the projecting areas. Therefore, it is an important subject for manufacturers in the related field to design an LED lamp with good directionality and even brightness. 
     As is generally known in the art, use has been made of varying kinds of illumination lamps for lightening or illuminating objects at night or indoors. Such illumination lamps are supplied with electric energy from a power source and convert the electric energy to light energy, thereby producing a beam of light for illumination. Typical examples of the illumination lamps include a glow lamp and a fluorescent lamp. 
     Widely used in recent years is a Light Emitting Diode (LED) illumination lamp that has a benefit of providing illumination of different colors, although higher in price than the typical lamps referred to above. However, the LED illumination lamp poses a drawback in that it tends to be heated up and shows decreased efficiency when used for more than a predetermined time period. Use of the LED lamp for a prolonged period of time may result in excessive heat generation, thus shortening the life span of the lamp. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide an LED illumination apparatus for spot lighting capable of assembling easily to reduce the assembling cost. 
     An object of the present invention is to provide an LED illumination apparatus for spot lighting capable of increasing the brightness of the LED illumination. 
     To achieve the above-mentioned object, the present invention includes a first base body, a first fixed element, a set of LED illumination module, and a second base body. The first base body has a first fixed portion. The set of first fixed element is mounted at the set of first fixed portion of the first base body, and has two relative first inclined faces. The set of LED illumination module has two light sources, which has a first end, that is fixed at the inclined faces of the first base and a second end. And second base body has a set of second fixed portion, wherein the second end of the light source is fixed at the second fixed portion.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to  FIG. 1-FIG .  7 , an LED illumination apparatus  100  for spot lighting of the present invention includes a first base body  10 , two set of first fixed element  20 , a set of LED illumination module  30 , a second base body  40 , two set second fixed element  50  and a set of shade  60 . 
     The first base body  10  has two set of first fixed portion  11 . 
     The two first fixed elements  20  are mounted at correspond to the first fixed portion  11  of the first base body  10 , wherein the two first fixed elements  20  have two relative first inclined faces  21 . Please referring to  FIG. 3B , the first fixed element  11  and the first base body  10  are integrally. 
     The LED illumination module  30  has two light sources  31 , which has first end  311  mounted at the inclined surfaces  21  and second end  312 , and the light sources  31  is formed with heat sink sheet  313 . 
     The second base body  40  has two set of second fixed portion  41 , as shown in  FIG. 6A . The second end  312  of the light source  31  is fixed at the second fixed portion  41  of the second base body  40 . 
     The two set of second fixed element  50  are mounted at the second fixed portion of the second base body  40 , and has two relative second inclined faces  51 , as shown in  FIG. 6A , wherein the second end  312  of the tight sources  31  is fixed at the second inclined faces  51  of the second base body  40 . Please referring to  FIG. 6B , the second fixed element  50  and the second base body  40  are integrally. And 
     The shade  60  is arranged between the first base body  10  and the second base body  40  for covering the LED illumination module  30 . The shade  60  is formed with heat dissipation holes  63  and has a left shade  61  and a right shade  62 , as shown in  FIG. 5 . 
     Therefore, according to the above-mentioned structure, after the LED lamp has been assembled, and the LED illumination module may spot lighting through the inclined faces  21  of the first fixed element  20 . 
     While the present has been described by way of an example and in terms of a preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiment. To the contrary, it is intended to cover various modifications. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modification.
