The bottom of described main casing shell is provided with back casing, and both fix by screw, and the back casing sidewall is provided with the streamlined projection of strip;
All be provided with optical lens on every lamp pearl of described led light source plate, fix by screw;
Described back casing is externally connected to bonnet, and the interior volume that both form is provided with constant-current supply.
Lamp body inside is provided with pressing plate, its be provided with the led light source plate on the fixing corresponding perforate of optical lens, the copper post that is provided with on the pressing plate passes pressing plate and the led light source plate is fixed on both on the main casing.
The contact-making surface that described protecgulum is connected with main casing is provided with the protecgulum sealing ring; The contact-making surface that described back casing is connected with bonnet is provided with the bonnet sealing ring.
The utlity model has following advantage:
The utility model uses single light source, adopts the optical lens of high pass light, and the lamp housing radiator structure of design hollow out cylinder, has improved the thermal diffusivity and the energy saving of explosion-proof lamp, has increased the service life of explosion-proof lamp; Built-in power is set, makes structure more concentrated, the lamp body volume is littler.
