BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The invention pertains to the field of container. More particularly, the invention pertains to improved container for electronic components. Yet more specifically, the invention pertains to improved container for ballasts with its associated electronics relating to a lighting device.  
         [0003]     2. Description of Related Art  
         [0004]     Enclosures for electronics are known. U.S. Pat. No. 4,903,167 to Lichtensperger discloses a casing for accommodating electronic components mounted on a printed circuit board, a lower box has a substantially U-shaped cross section, and includes a floor and at least two side walls. Each of the side walls has a horizontal slot proximate an upper edge thereof. At least one of the side walls has a resilient snap nose formed therein which is biased inwardly in the casing. A lid is also provided for closing the lower box, and the lid may have a closing edge thereon formed as a cross-sectionally double obtuse-angled stop tongue. A bead may be provided on a lower portion of the snap nose to orient a pc board in the casing.  
         [0005]     U.S. Pat. No. 6,225,559 to Hubner et al discloses a heat transfer housing for a printed circuit board, which has an electrical component having a thermal contact area. The housing includes an extruded section having a contact area and contours for receiving the printed circuit board. One of the walls of the housing that is initially formed displaces outwardly through an angle. When the printed circuit board is installed in the housing, the outwardly displaced wall is rotated inwardly and held in place by a cover. The wall includes a portion which bears against the printed circuit board and forces the thermal contact area of the electrical component to bear against the contact area of the housing for efficient heat transfer.  
         [0006]     U.S. Patent Application 20040184245 to Satoshi et al. discloses an electronic apparatus with a housing having one end, components contained in the housing, and a door which is lockable at a closed position to hide one end of the housing. The housing has a base to support the door, and a cover connected removable to the base. The cover is removed from the base by sliding toward the door, and hooked on the base by sliding away from the door. The door prevents the cover from sliding in the direction of separating the cover from the base, as long as being locked at the closed position.  
         [0007]     The known containers for electronics tend to use a plurality of parts. Also, the parts tend to possess elaborate shapes or forms that are complicated and expensive to make. Therefore, there is a need to have an enclosure that uses fewer parts, which are simple in structure. Further there is a need to have an enclosure that can be easily and securely assembled. Still further there is a need to have an enclosure that can be easily disassembled.  
       SUMMARY OF THE INVENTION  
       [0008]     An enclosure that uses fewer parts that are simple in structure is provided.  
         [0009]     An enclosure that can be easily and securely assembled is provided.  
         [0010]     An enclosure that can be easily disassembled is provided.  
         [0011]     An enclosure that can securely place electronics therein is provided.  
         [0012]     An enclosure for electronic device is provided.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0018]     Referring to  FIGS. 1-4 , an enclosure  10  for ballasts relating to a light device with a cover  12  and a base  14  is provided. Base  14  is formed out of a single piece having a bottom member  14   a  and a pair of opposite perpendicular members  14   b  formed substantially perpendicular to bottom member  14   a . On the inside of the perpendicular members  14   b , a pair of notches  22  are formed for receiving a circuit board  24  having electronic component thereon. Notches  22  may be a single groove form on the entire length of the inside of the perpendicular members  14   b , or alternatively only on selected locations along a pair of straight lines on the inside surface of perpendicular members  14   b . On the outside of bottom member  14   a , a pair flanges is formed or defined by the pair of opposite perpendicular members  14   b . The flanges may be used to affix enclosure onto a third member.  
         [0019]     Enclosure  10  relating to a lighting device further has a pair of side members  16  positioned opposite to each other, on the sides of enclosure  10  relating to a light device. Side member  16  is disposed to be rigidly affixed onto the unified whole of the cover  12  and base  14 . The affixing of the unified whole is achieved by forming a tongue  18  substantially along the edges of the entire length of cover  12  and a corresponding groove  20  along the edges of base  14 . Cover  12  may have a pair of flanges  12   a  bending with an angle or perpendicular to its main body having the edges for forming the tongue  18 . On the outside surface of the unified whole, there may be grooves or protrusions for such purposes as heat dissipation.  
         [0020]     At the corners of enclosure  10  relating to a light device, threaded receiving elements  26  are formed on the unified whole of both cover  12  and base  14 . Matching holes  28  are interposed between  26  and fixing members such as screws  30  for letting screws  30  to rigidly affix side member  16  onto the other members of enclosure  10  relating to a light device, i.e. cover  12  and base  14 .  
         [0021]     As can be seen, the preferred embodiment of the present invention has only limited number of parts to achieved the unified whole of enclosure  10  relating to a light device. In other words, cover  12 , base  14 , a pair of side members  16  and eight screws  30  may be the only parts used to form enclosure  10  relating to a light device. Additionally a pre-assembled circuit board  24  having electronic elements thereon has a pair of opposing edges disposed to slide into the inside of the unified whole via groove or receiving track  22  formed on the inside surface of perpendicular members  14   b.    
         [0022]     To assemble the present invention, cover  12  is gently pressed against base  14  whereby the tongue of cover  12  is meshed or engaged into the groove of base  14 . The two side members  16  are affixed onto the unified whole of cover  12  and base  14  by matching hole  28  of side member  16  with their corresponding receiving element  26  and using screws  30  for the resultant rigid affixation.  
         [0023]     The parts of the present invention may be formed of metal such as aluminum. Cover  12  and base  14  may be formed by extrusion, injection molding, or other type of pressurized forming means using such melted metal as aluminum. Alternatively, cover  12  and base  14  may be formed by sintering using powder metal.  
         [0024]     In an alternate embodiment, cover  12  may have the grooves and base  14  the tongues. Additionally, circuit board  24  may have edges with sufficient elasticity to be securely fit or squeezed into groove  22 . Through apertures may be formed on the parts of the present invention such as side  16  for letting such thing as electric wirings to pass therethrough.  
         [0025]     Accordingly, it is to be understood that the embodiments of the invention herein described are merely illustrative of the application of the principles of the invention. Reference herein to details of the illustrated embodiments is not intended to limit the scope of the claims, which themselves recite those features regarded as essential to the invention.
