BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure generally relates to lamps and, more particularly, to a light emitting diode (LED) lamp, wherein the LED lamp can be easily assembled and disassembled. 
         [0003]    2. Description of Related Art 
         [0004]    LEDs have many advantages, such as high luminosity, low operational voltage, low power consumption, compatibility with integrated circuits, easy driving, long term reliability, and environmental friendliness, which have promoted the wide use of LEDs as a light source. 
         [0005]    Conventionally, an LED lamp includes a light source having a plurality of LEDs, and a frame covering the light source. The frame is fixed on the LED lamp with screws. However, it is necessary to dissemble the frame from the LED lamp when one or more of the LEDs is broken and needs to be replaced or maintained. Both the dissembling and assembling require rotating the screws by using a screwdriver. These operations are laborious and time-consuming. In addition, in the process of disassembling or assembling the LED lamp, the screwdriver needs to be carefully operated; the LED lamp may be damaged due to a careless operation of the screwdriver to the screws. 
         [0006]    What is needed, therefore, is an LED lamp having a light source which can be easily assembled and disassembled.

     DETAILED DESCRIPTION 
       [0013]    Referring to  FIGS. 1 to 3 , an exemplary embodiment of an LED lamp  10  includes a shell  11 , a driver module  12  received in the shell  11 , a light source  12  received in the shell  11 , a fence  14  arranged on the light source  12 , and a plurality of locking members  15  mounted on the shell  11 . 
         [0014]    The shell  11  includes a bottom plate  111 , two first side plates  112  extending upwardly from two opposite sides of the bottom plate  111 , and two second side plates  113  extending upwardly from two ends of the bottom plate  111 . The bottom plate  111 , the first side plates  112  and the second side plate  113  cooperatively define a cavity  114  thereamong. An opening  115  is defined in a top of the cavity  114  opposite to the bottom plate  111 . The LED lamp  10  is fixed on a supporting member such as a ceiling via the bottom plate  111 . Each first side plate  112  defines a plurality of clasp holes  1121 , a plurality of locating holes  1122 , and a plurality of latch holes  1123 . Each one of the clasp holes  1121 , a corresponding one of the locating holes  1122  and a corresponding one of the latch holes  1123  are used to match with a corresponding locking member  15 . The clasp hole  1121  and the corresponding locating and latch holes  1122 ,  1123  are arranged in a line perpendicular to the bottom plate  111 , wherein the latch hole  1123  is located between the clasp hole  1121  and the locating hole  1122 . In other words, each locating hole  1122  is located below a corresponding clasp hole  1121 , and each latch hole  1123  is located between a corresponding clasp hole  1121  and a corresponding locating hole  1122 . The positions of the clasp holes  1121 , the locating holes  1122  and the latch holes  1123  at one of the first side plates  112  are the same as those at the other first side plate  112 . 
         [0015]    The driver module  12  is mounted on the bottom plate  111  and received in the cavity  114 . The driver module  12  is provided for supplying power to the light source  13 , whereby the light source  13  can obtain the required electrical power for generating light. 
         [0016]    The light source  13  is received in the cavity  114  of the shell  11 . The light source  13  is mounted on the bottom plate  111  via a holder  131 . In the present embodiment, the light source  13  includes a base  132 , and a plurality of LEDs  130  arranged on the base  132 , and a lens  133  spaced from the LEDs  130  and located at the light output path of the LEDs  130 . The holder  131  has a U-shaped configuration with a horizontal bottom portion and two vertical legs extending from two ends of the bottom portion. The bottom portion of the holder  131  is mounted on the bottom plate  111  of the shell, and the base  132  is arranged on the legs of the holder  131 ; therefore, the base  132  is spaced from the bottom plate  111 . 
         [0017]    A shape of the fence  14  is such configured that the fence  14  is fittingly received in the opening  115 . The fence  14  is fixed on the shell  11  via the locking members  15 . The fence  14  can protect the light source  13  and the driver module  12 . The fence  14  includes two side walls  142  inclined toward each other along a direction toward the base  132  of the light source  13 , and a plurality of spaced partitions  143  connected to and arranged between the two side walls  142 . The side walls  142  extend along a longitudinal direction of the base  132  of the light source  13 . The partitions  143  are parallel to each other, and each partition  143  is perpendicular with the side walls  142 . In other words, the partitions  143  extend along a transverse direction of the base  132  of the light source  13 . Inner surface (not labeled) of the side walls  142  and the outer surface (not labeled) of the partitions  143  can reflect light emitted from the LEDs  130 . Each side wall  142  defines a plurality of fixing holes  141 , and each fixing hole  141  corresponds to one of the clasp holes  1121  of the first side plates  112  of the shell  11 . 
         [0018]    Referring to  FIG. 4  also, the locking member  15  includes a securing portion  151  and a free elastic portion  152 . The elastic portion  152  includes a first portion extending from an end of the securing portion  151  and towards an inside of the shell  11 , and a second portion extending from the first portion of the elastic portion  152  and towards an outside of the shell  11 ; therefore, the elastic portion  152  has a substantially V-shaped configuration with an opening facing towards the outside of the shell  11 . The securing portion  151  defines a through hole  1511  at the other end away from the elastic portion  152 . The through hole  1511  corresponds to the latch hole  1123  of the shell  11 . An arced limiting protrusion  1512  is formed on the other end of the securing portion  151  away from the elastic portion  152 . The limiting protrusion  1512  locates at a position corresponding to a corresponding locating hole  1122  of the shell  11 , extends horizontally and is bent inwardly. 
         [0019]    Referring to  FIGS. 5 and 6  also, in assembly of the LED lamp  10 , each screw  153  is extended through a corresponding through hole  1511  of the locking member  15  and a corresponding latch hole  1123  of the shell  11  to fix the securing portion  151  on an outer surface of the first side plate  112  of the shell  11 . The limiting protrusion  1512  is engagingly received in the locating hole  1122  of the shell  11 ; therefore, the locking member  15  cannot rotate relative to the shell  11  about the corresponding screw  153 . The elastic portion  152  inserts into a corresponding clasp hole  1121  of the first side plate  112  and extends through the first side plate  112  to locate in the cavity  114  of the shell  11 . The fence  14  is located at the opening  115  of the shell  11  and pressed downwardly whereby the side walls  142  of the fence  14  abut the elastic portions  152  to make the elastic portions  152  deform. When the fence  14  reaches a predetermined position, the elastic portions  152  resume and each latch is in a corresponding fixing hole  141  of the fence  14 ; therefore, the fence  14  is fixed on the shell  11  via the clasp of the elastic members  15 . Light emitted from the LEDs  130  travels through the lens  133  and then radiates through the fence  14  to an outside for lighting. 
         [0020]    When the fence  14  needs to be detached from the shell  11 , the elastic portion  152  of the locking member  15  is pressed and elastically deformed towards the outside of the shell  11  to cause the elastic portion  152  to disengage from the fixing hole  141 ; therefore, the fence  14  is able to be pulled up from the shell  11 . 
         [0021]    By utilizing the locking member  15 , the fence  14  can be easily assembled and detached from the shell  11 .
