Electric current drives luminescent device.The drive circuit being connected with power supply and luminescent device, easily high current by when produce electric spark,
Its explosive-proof grade is higher.Individually be disposed in the first explosion-proof chamber 313, can with amplitude peak by its with the lantern external world every
From will fire odds and bottom out.
As shown in accompanying drawing 2, accompanying drawing 3, in the present embodiment, the first explosion-proof chamber 313 and second of connection is offered on dividing plate 312
The cable intake 315 of explosion-proof chamber 314；Charging inlet 316 is additionally provided with dividing plate 312, charging inlet 316 penetrates sealing tail
Lid 32, make the first explosion-proof chamber 313 and the ft connection of lamp tail 3.Above-mentioned cable intake 315 and charging inlet 316, without using
When, using gluing or seal and closed in the form of Capsule.Specifically, dividing plate 312 and tubular flame proof layer 311 are one
Body structure, to ensure the sealing between the first explosion-proof chamber 313 and the second explosion-proof chamber 314.
As shown in accompanying drawing 2, accompanying drawing 3, in the present embodiment, the second explosion-proof chamber 314 is provided with the control of control drive circuit
Circuit, control circuit are connected by cable intake 315 with drive circuit.The voltage and current grade that control circuit typically uses
Tell somebody what one's real intentions are, it is produced, and the probability of electric spark is relatively small, and therefore, its explosive-proof grade is low than drive circuit.Meanwhile control circuit
Due to being related to the interaction extraneous with lantern, when opening such as operator, close or adjust luminescent device brightness, it is required to
Control element in control circuit is manipulated, be disposed at the second explosion-proof chamber 314 be isolated with drive circuit to be formed it is double
The effect of weight flame proof.Its double flame-proof is advantageous to avoid that the reduction of lantern body seal performance may be caused during operation, so as to shadow
Ring the sealing of drive circuit.
As shown in Figure 4, in the present embodiment, operating key is provided with control circuit, external operation to be changed
The drive circuit being attached thereto is controlled for electric signal, is allowed to open, closes and carry out the brightness adjustment of luminescent device.Sealing
Tail-hood 32 be provided with the region corresponding to operating key can deformation unit 321, can the shape according to caused by external force of deformation unit 321
Become triggering operating key.Lid can deformation unit 321 technology of covering and transmission is realized using the epithelium of the material such as rubber or silica gel
Effect.
In a preferred embodiment, this can deformation unit 321 be opened in sealing tail-hood 32 on through hole and be located in this
Pass through upper elastic component.The periphery of elastic component is with being moved the operation of operator by elastic deformation by sealed connection, its body
It is delivered on operating key.
