Abstract
The utility model belongs to the technical field of mining lamps, disclosing a petrochemical explosion-proof platform lamp. The utility model adopts the main technical scheme that a shell of an explosion-proof glass cover is arranged on the front end, and a panel with a plurality of lamp holes, a LED light source base plate corresponding to the lamp holes and a circuit board for controlling an LED light source are arranged inside the shell in turn, wherein LED light sources corresponding to the lamp holes are installed on the light source base plate, and a plurality of separate slots are arranged on the circuit board to divide the circuit board into a plurality of circuits for controlling the LED light source, and the LED light source control circuits 12, 13 are connected with a power bus of the circuit through a switch. The petrochemical explosion-proof platform lamp adopts the LED light source as the light source, and has the characteristics of small power consumption and long service life.
Description
Technical field
The utility model belongs to mining technical field of lamps, discloses a kind of petrochemical industry explosion-proof platform lamp specifically.
Prior art
At present, the structure of various petrochemical industry explosion-proof platform lamps all is that an incandescent lamp bulb, metal halide bulb, mercury lamp bulb or fluorescent tube and single channel power patch panel formation are set in lamp casing.The petrochemical industry explosion-proof platform lamp of this kind structure, one, because employed light source power is big, light efficiency is low, and the temperature height that produces, and the humidity of employed environment is abominable, very easily produces water smoke and have a strong impact on illuminating effect in its lampshade; Its two because terminal plate is the single channel power supply architecture,, just exist the defective that makes that whole petrochemical industry explosion-proof platform lamp is scrapped as long as there are electronic devices and components to damage in the power circuit; Its three, this petrochemical industry explosion-proof platform lamp also exists the defective of function singleness.
The content of utility model
The purpose of this utility model is exactly, and provides that a kind of power consumption is little, the petrochemical industry explosion-proof platform lamp of long service life.
For realizing that the technical scheme that the utility model purpose is adopted is:
A kind of petrochemical industry explosion-proof platform lamp, its structure comprise that front end is provided with the housing of cloche,
Described enclosure interior front end be disposed with panel with several lamp holes,
The circuit board of the light source substrate that be provided with light source corresponding with described lamp hole and control light source cuts off slot with it separation by at least one on this circuit board,
The led light source corresponding with described lamp hole is installed on described light source substrate,
On the circuit board that described slot is separated, be respectively arranged with the circuit of control led light source.
Petrochemical industry explosion-proof platform lamp provided by the utility model compared with prior art has the following advantages: one because the light source that this petrochemical industry explosion-proof platform lamp adopts is a led light source, therefore has the characteristics of the little and long service life of power consumption; They are two years old, owing to cut off slot with it separation by at least one on this petrochemical industry explosion-proof platform lamp circuit board, and on the circuit board that slot is separated, be respectively arranged with the circuit of control led light source, one road circuit damages can in time switch another circuit, can effectively guarantee the operate as normal of petrochemical industry explosion-proof platform lamp;
Description of drawings
Fig. 1 is the structural representation of petrochemical industry explosion-proof platform lamp;
Fig. 2 is the structural representation of panel, light source substrate and the circuit board of above-mentioned petrochemical industry explosion-proof platform lamp.
The specific embodiment
Be described in further detail below in conjunction with the structure and the operation principle of accompanying drawing petrochemical industry explosion-proof platform lamp provided by the utility model:
As illustrated in fig. 1 and 2, be the structural representation of petrochemical industry explosion-proof platform lamp provided by the utility model.Its structure comprises that front end is provided with the housing 1 of protection network 2 and explosion-proof glass cover 16 cloches, is disposed with panel 5 with several lamp holes 4, the led light source substrate 7 corresponding with lamp hole and the circuit board of control led light source in enclosure interior; The led light source corresponding with lamp hole 3 is installed on light source substrate 7; The foregoing circuit plate is provided with partition slot 9 it is separated into two parts 10 and 11, be fixed with the circuit 12 and 13 of controlling led light source respectively at this two-part circuit board 10 and 11 that is divided into, this led light source control circuit 12 is connected with the power bus 14 of circuit by the change-over switch 15 that is fixed on the housing with 13.This petrochemical industry explosion-proof platform lamp only need be connected the simple functions that power bus can be realized mining platform, because the light source that adopts is a led light source, therefore has the characteristics of the little and long service life of power consumption.Can realize switching between two-way circuit 12 and 13 in use by change-over switch, effectively guarantee the operate as normal of petrochemical industry explosion-proof platform lamp.
Cut off slot 9 on the foregoing circuit plate and can several be set as required, be about to circuit board and be divided into needed fritter, the circuit power of control led light source is installed on each fritter then, and is switched, to improve its utilization rate by change-over switch 15 controls of being fixed on the housing.
Claims (1)
1, a kind of petrochemical industry explosion-proof platform lamp, its structure comprise that front end is provided with the housing of cloche, is characterized in that:
Described enclosure interior front end be disposed with panel with several lamp holes,
The circuit board of the light source substrate that be provided with light source corresponding with described lamp hole and control light source cuts off slot with it separation by at least one on this circuit board,
The led light source corresponding with described lamp hole is installed on described light source substrate,
