Disclosed are a lamp radiator and an LED lamp for mining use having the lamp radiator. The lamp radiator comprises a heat source plate (1), a fixed ring (2), a fixed plate (3) and a plurality of heat dissipation fins (4), wherein the plurality of heat dissipation fins (4) form a circular array and there are gaps among the heat dissipation fins (4). The upper end of each heat dissipation fin (4) is fixed to the fixed ring (2) and the fixed plate (3), and the lower end of each heat dissipation fin (4) is fixed to the heat source plate (1) and is in direct contact with the heat source plate (1). The lamp radiator is provided with the plurality of heat dissipation fins (4) and there are gaps among the heat dissipation fins (4), which are beneficial for the hot gas circulation and able to accelerate the heat dissipation; and in addition, the lamp radiator is not a single component and can significantly reduce the weight of the lamp. |
