In explosion-proof type LED roadway lamp for mine provided by the present invention, described light-emitting device comprises on LED, the LED drive board be connected with described LED and fixture thereof, the insulating screw be connected with described LED drive board and cable entry, described LED lens is housed.
In explosion-proof type LED roadway lamp for mine provided by the present invention, there is 1 light-source chamber in described lamp housing front, there are 2 cavitys (wire connection cavity and electric apparatus chamber) at the lamp housing back side, wire connection cavity is connected with light-source chamber by 2 insulating screws, electric apparatus chamber is connected with light-source chamber by 4 binding posts, so forms 3 completely independently cavitys.
In explosion-proof type LED roadway lamp for mine provided by the present invention, electric apparatus chamber and wire connection cavity divide left and right side by side, and are formed two-layer up and down with light-source chamber.And one deck light-source chamber, two layers of completely independent and electric apparatus chamber arranged side by side and wire connection cavity.
In explosion-proof type LED roadway lamp for mine provided by the present invention, described light-source chamber is equipped with copper pad and safety glass; Described electric apparatus chamber is equipped with LED drive board; Described wire connection cavity is equipped with external cable; Described wire connection cavity and electric apparatus chamber coordinate assembling by bonnet 9 and bonnet 11.
In explosion-proof type LED roadway lamp for mine provided by the present invention, described copper pad and safety glass are assembled by panel and screw in compression; LED drive board fixed bit is provided with in electric apparatus chamber; The screw thread that insulating screw coordinates is provided with in wire connection cavity.
In explosion-proof type LED roadway lamp for mine provided by the present invention, described lamp housing front edge has a groove, coordinates with mounting and fixing support for during installation by adhering.
In explosion-proof type LED roadway lamp for mine provided by the present invention, described lamp housing, bonnet 9, bonnet 11 material are by ADC12 die cast.
The invention has the beneficial effects as follows, providing under the prerequisite meeting national colliery product explosion-proof performance, electric apparatus chamber and wire connection cavity divide left and right side by side, and are formed two-layer up and down with light-source chamber, and reduce light fixture height, light fixture whole height is low, is beneficial to down-hole installation by adhering.Thering is provided under the prerequisite meeting national colliery product explosion-proof performance, electric apparatus chamber is connected by 4 binding posts with light-source chamber, be in complete separate state, the heat of light-source chamber can not enter electric apparatus chamber, ensure that the temperature of electric apparatus chamber is in minimum state (environment temperature), thus effectively ensure that the useful life of electric capacity and components and parts in LED drive board.
