Description
Affiliated technical field
The utility model content belongs to the semiconductor lamp technical field, relates to a kind of mine locomotive flame-proof type semi-conductor lighting lamp.
Background technology
Mine locomotive all adopts 24V 35W incandescent lamp to make lighting usually at present, and the disadvantage of this light fixture is that power consumption is big, and the life-span is extremely short.Because locomotive needs continuous illumination in the down-hole, and the service time of incandescent lamp is very short, therefore the mining area all will be dropped into lot of manpower and material resources locomotive light is changed maintenance every year, maintenance cost height not only, also there are many unsafe factors in the attended operation process, have a strong impact on the normal operation of locomotive.In addition, because the supply voltage of mine is 127V, in order to give the locomotive light power supply of 24V down-hole, on locomotive, just a switching mode DC-DC converter apparatus must be installed specially, so not only increased cost of equipment, and after the DC-DC converter apparatus broke down, even the underground power supply system normal power supply, locomotive light also can't throw light on.
In recent years, along with the fast development of semiconductor lighting technology, white light emitting diode (WLED) has been widely used in mining safety helmet lamp and flame proof tunnel illuminating lamp.The power consumption of this novel illumination lamp is minimum, luminous flux is (80Lm/w) greatly, life-span extremely long (theoretical 100000 hours life-spans), and WLED is powered by DC low-voltage, along with development of electronic technology, adopt the wide power scope 24V～220V AC-DC conversion control circuit is directly controlled the WLED lamp very feasible, therefore also need on locomotive, dispose the DC-DC converter apparatus that aims at the locomotive light power supply, so the WLED lamp has become the optimal light source that throws light under the mine.At present, because the rated power of single WLED is less, still can not reach the requirement of normal illumination, therefore generally all adopt the form of many WLED arrays, its most frequently used method is to arrange that on a planar circuit board many WLED form the lamp array.But this lamp array remain major defect be that illumination range is narrower, can not satisfy the lighting requirement of many real work occasions, in addition, when power supply interrupts, can not guarantee emergency lighting, therefore aspect applying, also have big difficulty.
The utility model content
The purpose of this utility model is the problem that prior art exists is solved, so provide a kind of rational in infrastructure, easy to operate, power consumption is little, long service life, good illumination effect and can guarantee the wide power scope continuous illumination flame proof mine WLED locomotive light of emergency lighting.
Be used to realize that the technical solution of foregoing invention purpose is such: the wide power scope continuous illumination flame proof mine WLED locomotive light that is provided is by the flame proof lampshade, the integrated control circuit that is encapsulated in the electroluminescence body in the flame proof lampshade and is provided with lamp body, reserve lithium battery group and charge-discharge circuit thereof are formed, wherein said electroluminescence body has a column type radiator by at least three coaxial lamination suits of aluminum-base printing circuit board sheet, lower surface at column type radiator bottom circuit board wafer evenly is laid with many semi-conductor lighting lamp pearls (WLED) that connect with control circuit, evenly is laid with many semi-conductor lighting lamp pearls that connect with control circuit in the periphery of remaining circuit plate.
Compared with prior art, the utility model adopts after on the aluminum-base printing circuit board WLED being installed, again multilayer circuit board is combined into column type electroluminescence body, though the luminous flux of single WLED is less, irradiating angle is also less, after but many WLED formed array, the irradiating angle of locomotive light and irradiation distance all can satisfy the locomotive lighting requirement.Because each WLED is by 24V～220V wide power scope power supply, therefore need on locomotive, not dispose the expensive DC-DC converter apparatus that aims at the locomotive light power supply again, and can also realize locomotive light brightness, temperature, driving voltage and drive current Comprehensive Control, prolong the service life of WLED locomotive light greatly.In addition, in the past under the situation of underground power supply used power interruptions, in order to guarantee the locomotive light continuous illumination, must dispose the energy storage battery on the locomotive, when adopting the bigger incandescent lamp of power to make lighting, battery must have very big capacity, be about 1.5A such as 24V 35W incandescent lamp supply current, incandescent lamp was lighted 10 hours, and the minimum capacity of battery should be 24V 15Ah (360wh), and jumbo like this battery can't be installed in the locomotive light.And adopt WLED locomotive light described in the utility model, power demand to be about 3W, and supply current is 1A, and the WLED lamp was lighted 10 hours, and the minimum capacity of battery is 3.6V 10Ah (36wh).What the ferric phosphate lithium cell that security performance is fabulous was successful in recent years uses under mine, only needs the lithium battery of 1 10Ah can guarantee continuous illumination in 10 hours.

The specific embodiment
Referring to accompanying drawing, electroluminescence body (bulb), WLED lamp integrated control circuit, lithium battery group and charge-discharge circuit, flame proof lampshade etc. that wide power scope continuous illumination flame proof mine WLED locomotive light described in the utility model mainly is made up of WLED lamp array are partly formed.The electroluminescence body is encapsulated in the flame proof lampshade, as shown in Figure 1, it is made up of three layers of aluminum-base printing circuit board 1 closed assembly that is provided with many super brightness semi-conductor lighting lamp pearls (WLED) 2, wherein the lower surface at bottom printed circuit board (PCB) 1 evenly is laid with many WLED, and 1 of all the other two-tier circuit plate are evenly to lay many WLED in periphery.During assembling, each layer aluminum-base printing circuit board 1 usefulness metal screw is coupled together, constitute an integral heat sink device, the heat that WLED is produced leaves rapidly.For guaranteeing when power supply interrupts, locomotive light still can emergency lighting, in the semi-conductor lighting lamp pearl 2 that constitutes the electroluminescence body, the secondary light source semi-conductor lighting lamp pearl (be standby lighting lamp) of lamp pearl for connecting with reserve lithium battery group charge-discharge circuit that a no more than half is arranged, remaining most of lamp pearl are the main light source semi-conductor lighting lamp pearl (the promptly main illuminating lamp of using) that connects with the control power circuit.
