Title: Wall lamp

Description:
FIELD OF THE INVENTION 
     The present disclosure relates to a technical field of lightings, and more particularly relates to a wall lamp. 
     BACKGROUND OF THE INVENTION 
     As one type of lightings, wall lamp is extensively applied to public places such as residential areas, tourist attraction, park, plaza, private garden, and courtyard corridor. However, the conventional wall lamp has an immobilized structural design, and a light emission angle or a light emission orientation of the wall lamp cannot be adjusted accordingly, thus it possesses a single function and a poor flexibility. 
     SUMMARY 
     Accordingly, it is necessary to provide a wall lamp which can realize an adjustment of a light emission angle or a light emission direction. 
     A wall lamp includes a main frame including a first side portion, a second side portion, a third side portion, and a fourth side portion that are connected to each other successively; a luminous component located in the main frame; a first blocking plate, a second blocking plate, a third blocking plate, and a fourth blocking plate positioned on the first side portion, the second side portion, the third side portion, and the fourth side portion, respectively; an upper blocking plate positioned on a top portion of the main frame; and a base assembled to a bottom portion of the main frame; wherein at least one of the first blocking plate, the second blocking plate, the third blocking plate, the fourth blocking plate, and the upper blocking plate is a detachable shielding plate. 
     The details of one or more embodiments of the invention are set forth in the accompanying drawings and the description below. Other features, objects, and advantages of the invention will be apparent from the description and drawings, and from the claims.

The top portion of the main frame  100  defines a fifth light emitting outlet  151 , the upper blocking plate  350  is configured to seal the fifth light emitting outlet  151 . 
     At least one of the first blocking plate  310 , the second blocking plate  320 , the third blocking plate  330 , the fourth blocking plate  340 , and the upper blocking plate  350  is a detachable shielding plate, the residual can be detachable transparent plates, or can be transparent plates which are fixed assembled, or can be detachable shielding plates. 
     In an embodiment, all of the first blocking plate  310 , the second blocking plate  320 , the third blocking plate  330 , the fourth blocking plate  340 , and the upper blocking plate  350  are detachable shielding plate. In another embodiment, the upper blocking plate  350  is a transparent plate which is detachably assembled, and the first blocking plate  310 , the second blocking plate  320 , the third blocking plate  330 , and the fourth blocking plate  340  are detachable shielding plates. It should be noted that aforementioned shielding plates can be glass sheets with a lower light transmittance, and also can be opaque plastic sheets or wood sheets. Aforementioned transparent plates can be glass sheets or plastic sheets with a higher light transmittance. Specifically, an edge of the upper blocking plate  350  defines a plurality of assembly holes which are configured for threaded fasteners to extend through to assembly the upper blocking plate  350  to the top portion of the main frame  100 . 
     According to requirements in different scenarios, any one or several of the first blocking plate  310 , the second blocking plate  320 , the third blocking plate  330 , the fourth blocking plate  340 , and the upper blocking plate  350  are reasonably configured to adopt a detachably assembly mode or a fixed assembly mode, and is reasonably configured to be a shielding plate or a transparent plate, causing an light emission angle or a light emission direction of the luminous component  200  can be adjusted by virtue of a shifting operation between the shielding plate and the transparent plate. 
     The luminous component  200  includes a light transmissive lampshade  210  and a light emitting unit  225 , the light transmissive lampshade  210  covers the base  360 , the light emitting unit  225  is positioned on the base  360  and is received in the light transmissive lampshade  210 . The light emitting unit  225  includes a circuit plate  221  and a plurality of LED lamps  222  soldered to the circuit plate  221 . The wall lamp  10  further includes a cover plate  400  detachably assembled to the base  360 , a bottom portion of the base  360  which is opposite to the light transmissive lampshade  210  defines a containing groove  361 , the cover plate  400  seals the containing groove  361 , an electronic component is provided in the containing groove  361  and is electrically connected to the circuit plate  221 . The electronic component in the containing groove  361  can be repaired or replaced by a disassembly of the cover plate  400 . 
     As shown in  FIG. 4  through  FIG. 7 , in the embodiment, the top portion of the main frame  100  defines a latching groove  152 , the bottom portion of the main frame  100  are provided with a plurality of bending buckles  162 . An edge of each of the first blocking plate  310 , the second blocking plate  320 , the third blocking plate  330 , and the fourth blocking plate  340  defines a positioning hole for the bending buckle  162  to detachably latch in, the other edge extends into the latching groove  152 . Each of the first blocking plate  310 , the second blocking plate  320 , the third blocking plate  330 , and the fourth blocking plate  340  has an L-shaped structure, includes a vertical plate and a lateral plate extending perpendicular to the vertical plate, the positioning hole is defined on the lateral plate, an edge of the vertical plate away from the lateral plate extends into the latching groove  152 . The bottom portion of the main frame  100  is provided with a convex edge  163  which is positioned toward the bending buckle  162 , when the bending buckle  162  is latched in the positioning hole, the convex edge  163  compresses the lateral plate. 
     Taking the fourth blocking plate  340  for example, the fourth blocking plate  340  includes a vertical plate  341  and a lateral plate  342  perpendicular to the vertical plate  341 . The lateral plate  342  defines a plurality of positioning holes  343 , an edge of the vertical plate  341  which is away from the lateral plate  342  extends into the latching groove  152 . The bending buckle  162  is latched in the positioning hole  343 , to realize a firmly and detachably assembly of the fourth blocking plate  340  to the fourth side portion  140 . Further, the bottom portion of the main frame  100  is provided with the convex edge  163  positioned toward the bending buckle  162 , the convex edge  163  compresses the lateral plate  342 , thus when the bending buckle  162  is latched in the positioning hole  343 , the convex edge  163  can limit a shaking of the lateral plate  342 . The structures and assembly modes of the first blocking plate  310 , the second plate  320 , and the third blocking plate  330  can be obtained by referring to the fourth blocking plate  340 , and are not specifically described herein. 
     In the embodiment, an edge of the light transmissive lampshade  210  is bended outwardly to form a bending portion  211 , the bending portion  211  extends into a limiting region  510  formed between the base  360  and the main frame  100 . 
     In aforementioned wall lamp  10 , by virtue of reasonably configured at least one of the upper blocking plate  350 , the first blocking plate  310 , the second blocking plate  320 , the third blocking plate  330 , and the fourth blocking plate  340  to be a detachable shielding plate, a light emission angle or a light emission direction of the luminous component  200  in the main frame  100  can be adjusted, and it meets requirements of different scenarios, thereby obtaining multi-functions and a better flexibility. 
     The above are several embodiments of the present invention described in detail, and should not be deemed as limitations to the scope of the present invention. It should be noted that variations and improvements will become apparent to those skilled in the art to which the present invention pertains without departing from its spirit and scope.
