     DETAILED DESCRIPTION 
       [0012]    Referring to  FIG. 1 , an LED lamp assembly  1  according to a first embodiment is shown. The LED lamp assembly  1  includes a lamp body  10 , a bracket  30  supporting the lamp body  10 , and a securing member  50  moveably engaging with the bracket  30  to press a part of the lamp body  10  thereby securing the lamp body  10  to the bracket  30 . 
         [0013]    Referring also to  FIG. 2 , the lamp body  10  includes an elongated supporting plate  11 , an LED module  13  mounted on a top surface of the supporting plate  11 , two legs  15  respectively extending down from opposite ends of a bottom surface of the supporting plate  11 , and a plurality of fins  17  extending down from the bottom surface of the supporting plate  11 . The fins  17  are located between the two legs  15 . 
         [0014]    The LED module  13  includes an elongated printed circuit board  131  fixed on the top surface of the supporting plate  11  and a plurality of LEDs  133  mounted on the printed circuit board  131  along a longitudinal direction of the printed circuit board  131 . 
         [0015]    Each leg  15  includes an extending part  151  perpendicularly extending from the supporting plate  11  and a contacting part  153  bended from a bottom end of the extending part  151 . The extending part  151  is elongated. The contacting part  153  is rectangular. 
         [0016]    The bracket  30  includes an elongated bottom plate  31  and two sidewalls  33  extending upwardly from opposite ends of the bottom plate  31  and perpendicularly connecting the bottom plate  31 . Two tabs  35  protrude from a top surface of one end of the bottom plate  31  (right end shown in  FIG. 2 ). The tabs  35  are spaced from and face each other. A through hole  351  is defined in each tab  35 . In this embodiment, the tab  35  is generally rectangular. An engaging plate  37  is formed on the other end (left end in  FIG. 2 ) of the bottom plate  31 . The engaging plate  37  is curved and edges thereof connect the top surface of the bottom plate  31 . The engaging plate  37  and the bottom plate  31  cooperatively define a receiving chamber  373  therebetween with an opening  371  facing the right end of the bottom plate  31 . 
         [0017]    The securing member  50  is fixed on the tabs  35 . The securing member  50  is generally U-shaped, and includes a rectangular pressing plate  53  and two connecting plates  51  perpendicularly extending from opposite ends of the pressing plate  53 . Each connecting plate  51  is rectangular with a guiding groove  511  defined therein. A distance between outer surfaces of the connecting plates  51  is equal to or slightly less than that between inner surfaces of the tabs  35  of the bracket  30 . In this embodiment, the guiding groove  511  is L-shaped and includes a straight first groove  5112  extending along a longitudinal direction of the connecting plate  51  and a straight second groove  5114  perpendicularly and downwardly extending from a top end of the first groove  5112 , as viewed from  FIG. 2 . 
         [0018]    Referring also to  FIG. 3 , the securing member  50  is arranged between the tabs  35  of the bracket  30  with the pressing plate  53  at the right side of the tabs  35 . The first grooves  5112  of the securing member  50  are aligned with the through holes  351  of the tabs  35 , respectively. Two pins  60  extend through the through holes  351  and the first grooves  5112  to assemble the securing member  50  and the bracket  30  together. 
         [0019]    The lamp body  10  is arranged on the bottom plate  31  of the bracket  30 . The contacting part  153  of the leg  15  at the left end of the lamp body  10  is inserted in the receiving chamber  373  through the opening  371 , and the contacting part  153  of the leg  15  at the right end of the lamp body  10  is arranged between the tabs  35 . Referring again to  FIG. 1 , the securing member  50  is then operated to rotate about the pins  60  to make the pressing plate  53  of the securing member  50  positioned above the contacting part  153 . In this state, the pressing plate  53  is spaced from the extending part  151 , and the pins  60  are located at the lowest ends of the first grooves  5112 , respectively. Then an elastic pad  55  is inserted between the contacting part  153  and the pressing plate  53 . Thereafter, the pressing plate  53  is pushed downwardly towards the contacting part  153  until the pins  60  reach the intersections between the first grooves  5112  and the second grooves  5114 , whereby the pressing plate  53  presses the elastic pad  55  downwardly against the contacting part  153 . Finally, the securing member  50  is moved leftward until the pressing plate  53  abuts the extending part  151  and the pins  60  are located in the rightmost ends of the second grooves  5114 , which are remote from the first grooves  5112 . Therefore, the lamp body  10  is assembled on the bracket  30  completely and securely. 
         [0020]    In disassembly, the above process is reversed. The securing member  50  is moved rightwards. The elastic pad  55  is then removed. Finally, the securing member  50  is rotated clockwise as viewed from  FIG. 3  to leave the extending part  151 . 
         [0021]    In this embodiment, the lamp body  10  is secured to the bracket  30  without using any screws. The assembly and disassembly of the LED lamp assembly  1  can be easily achieved. 
         [0022]    Referring to  FIGS. 4-5 , an LED lamp assembly la of a second embodiment is shown. In this embodiment, the securing member  50   a  is different from the securing member  50  of the first embodiment. The securing member  50   a  includes two spaced and parallel mounting plates  51   a,  a linking plate  53   a  located between and connecting with the mounting plates  51   a,  and a handle  55   a  extending upwardly from a right side of the linking plate  53   a.  Each mounting plate  51   a  is a rectangular sheet. The two mounting plates  51   a  are aligned with each other. The linking plate  53  is a U-shaped sheet and opposite ends thereof connect with the mounting plates  51   a,  respectively. The handle  55   a  is a semicircular sheet and located at a top of the mounting plate  51   a  for facilitating users to operate the securing member  50   a.    
         [0023]    Two spaced clips  70  are formed on the bottom plate  31  and engage with the securing member  50   a.  Each clip  70  includes a rectangular connecting sheet  71  extending upwardly from the top surface of the bottom plate  31 , a rectangular extending sheet  73  bended rightward from a top end of the connecting sheet  71 , and an arc-shaped restricting sheet  75  extending downwardly from an outer side of the extending sheet  73 . The extending sheet  73  is parallel to the bottom plate  31 . The restricting sheet  75  is convex. The largest distance between the two restricting sheets  75  is slightly larger than or equal to a distance between outer edges of the mounting plates  51   a.    
         [0024]    Two elastic arms  80  protrude from the top surface of the bottom plate  31  and between the clips  70  and the right sidewall  33 . The elastic arms  80  are aligned with the clips  70 , respectively. A rightmost end of the elastic arm  80  is away from the clip  70  and connects the bottom plate  31 , and the other part thereof is spaced from the bottom plate  31  and located over a top of the bottom plate  31 . A distance between a bottom surface of the elastic arm  80  and the top surface of the bottom plate  31  generally gradually increases from right to left. A left end of the elastic arm  80  which is adjacent to a right end of the clip  70  is slightly bended towards the bottom plate  31  of the bracket  30 . A slit  313  is defined in the bottom plate  31  and below the elastic arm  80  to receive the elastic arm  80  therein when the elastic arm  80  is pressed. 
         [0025]    When the lamp body  10  is assembled on the bracket  30 , the left leg  15  engages with the engaging plate  37 , firstly. The contacting part  153  of the right leg  15  contacts the top surface of the bottom plate  31  and is located between the two clips  70 . Then the securing member  50   a  is assembled to the bracket  30  to press the contacting portion  153  of the right leg  15 . The mounting plates  51   a  are arranged on the elastic arms  80 . The securing member  50   a  is pressed downwardly and slides along the elastic arms  80  in a direction parallel to the bottom plate  31  until the mounting plates  51   a  are inserted in the two clips  70 , respectively. In this state, right and left ends of each mounting plate  51   a  respectively abut the connecting sheet  71  and the left end of the corresponding elastic arm  80 , and a lateral side of each mounting plate  51   a  abuts the corresponding restricting sheet  75 . The linking sheet  53   a  presses the contacting part  153  of the right leg  15 . 
         [0026]    When the lamp body  10  is disassembled from the bracket  30 , the elastic arms  80  are pressed toward the bottom plate  31  of the bracket  30 , and the securing member  50   a  is pulled rightwards away from the clips  70  until the securing member  50   a  separates from the contacting part  153  of the right leg  15 . Thereafter, the lamp body  10  is pulled rightward to be disassembled from the engaging plate  37 . Thus, the lamp body  10  is disassembled from the bracket  30 .
