The electric circular saw provided by the present invention uses the fixed shield to indirectly increase the heat dissipation area of the heat sink, and because the fixed shield is directly in contact with the outside air, the heat dissipation efficiency of the power board can be further improved, and there is no need to install a special cooling air The power board is dissipated through the circuit, so that the cooling air circuit can be simplified.

An efficient heat dissipating lamp comprises a heat dissipating base, a supporting table body, a heat dissipating rotary wing plate assembly and LED illuminating bodies. The supporting table body is arranged on the heat dissipating base. A heat dissipating containing groove is formed in the side edge of the supporting table body. The heat dissipating rotary wing plate assembly comprises a rotary shaft and a plurality of rotary wing plates. The rotary shaft and all the rotary wing plates are all contained in the heat dissipating containing groove. The two ends of the rotary shaft are fixed to the two opposite inner side walls of the heat dissipating containing groove correspondingly. The rotary shaft rotates in sequence and penetrates through one ends of the rotary wing plates, and the rotary wing plates are arranged at intervals. When the efficient heat dissipating lamp is in the transportation process, all the rotary wing plates are contained in the heat dissipating containing groove, thus, the surface of the overall structure is more flat, the number of protruding structures is smaller, the efficient heat dissipating lamp is easy to store and package in a concentrated mode, limitation to packaging operation is smaller, when the efficient heat dissipating lamp needs to be used, the ends, away from the rotary shaft, of the rotary wing plates are made to stretch out of the heat dissipating containing groove, the thermal radiation effect and the thermal convection heat dissipation effect can be improved, and the heat dissipating performance is better.
