     As shown in  FIG.  1   , a multi-angle lighting lamp, including: lamp holder  170 , lamp boards  200  and protective covers  300 ; a plurality of lamp boards  200  are connected with the lamp holders  170 , and a plurality of lamp boards  200  are situated around the center of the lamp holder  170  and thus forming the lamp cavity, and lamp boards  200  are provided with the lamp bead  210  and heat dissipation part  250 , and the heat dissipation part  250  is bent and extended into the lamp cavity relative to the lamp broad  200 ; a plurality of protective covers  300  is connected to the lamp board  200  one by one, and the protective covers  300  are covered on the lamp beads  210 ; there is a heat sink  150  between two adjacent protective covers  300 , and the heat sinks  150  are communicated with the lamp cavity. After the lamp holder  170  is connected to the scene, the lamp beads  210  on the lamp board  200  will be able to emit light to achieve the lighting effect. The surrounding distribution of multiple light boards  200  relative to the lamp holder  170  enables multiple light boards  200  to cooperate with different directions of the lamp holder  170  to achieve multi-angle lighting effect. And the protective cover  300  can not only protect the lamp bead  210 , but the heat dissipation  150  between the two adjacent protective covers  300  can make the outside air flow pass through the heat dissipation mouth  150  and flow to the lamp cavity, so as to drive the heat of the heat dissipation part  250  through the other heat dissipation mouth  150 , so as to cooling the heat dissipation part  250 . By setting the heat dissipation part  250  on the lamp board  200  in the lamp cavity, and by configuring the heat dissipation mouth  150  to form a convection channel inside the lamp cavity, the air flow can directly and effectively blow the heat dissipation part  250 , so that the air flow can better take away the heat of the heat dissipation part  250 . Thus, the heat on the lamp board  200  is effectively discharged through the heat dissipation part  250 , so the overall heat dissipation efficiency of the lamps and lanterns will be greatly improved. Also, multiple hollowed heat dissipation mouth  150  and lamp cavity can greatly reduce the overall weight, thus facilitating the transportation and assembly process.
