Abstract
The utility model relates to a mining explosion-proof type LED (light emitting diode) light source roadway lamp, which is provided with a lamp holder with an upper cover, wherein a drive circuit board is arranged in the lamp holder, an LED light source which is electrically connected with the drive circuit board is arranged on a lower bottom panel of the lamp holder, and is encapsulated by a transparent lamp cover, a mining cable connecting hole is arranged in each of the two side walls of the lamp holder. In the roadway lamp, the high-power LED cold light source is used as a roadway lamp luminophor, so that the mining explosion-proof type LED light source roadway lamp has the advantages of small volume, light weight, high luminous efficacy, low energy consumption, long service life, long projection range, high illumination, good impact resistance, good vibration resistance and the like, the safe and reliable operation of the roadway lamp are ensured, and the roadway lamp is accordance with the national policy for energy saving and emission reduction.
Description
Technical field
The utility model belongs to field of illumination lamp technology; Relate to a kind of flame-proof mine led light source tunnel lamp; This tunnel lamp is mainly used in the walking and the operation illumination of development machine and other digging, Transport Machinery under the coal mine of gas and coal dust explosion hazard, also can be used for the illumination that oil, chemical industry etc. have damp hazardous area plant equipment.
Background technology
Along with the high speed development of China's economic construction, demands for energy is also being developed rapidly with surprising rapidity, for this reason a coal very important pillar in becoming Chinese national economy already.The flame-proof type light fixture of mine laneway illumination of in the past in the long duration, being used to mine all adopts traditional incandescent lamp; This light fixture is because power consumption is big especially, the life-span is extremely short, maintenance cost is high and illumination and light efficiency are all very low; Become restriction China coal mining industry and carried out a big obstacle of the low-cost policy of national energy-saving and emission-reduction, just abandoned for most of mine gradually.Present many mines have all adopted advanced mine explosion-suppression fluorescent lamp; But because mine laneway needs continuous illumination; And the life-span of fluorescent lamp is shorter; Annual mining area all will be dropped into lot of manpower and material resources the tunnel lamp is changed maintenance, and not only maintenance cost is very big, also has many unsafe factors in the attended operation process; In addition, fluorescent lamp has serious mercury, is not green illumination, still can not well satisfy the state basic policy requirement of the energy-saving and emission-reduction that country vigorously advocates.
The utility model content
The purpose of the utility model is to overcome the defective that prior art exists, and provides that a kind of volume is little, in light weight, light efficiency is high, energy consumption is low, long service life, projection distance is far away, illumination is big and the flame-proof mine led light source tunnel lamp shock-resistant, that anti-vibration performance is good.
For realizing that the technical solution that the foregoing invention purpose adopts is such: the flame-proof mine led light source tunnel light fixture that is provided has the lamp socket (power supply cavity) of a band loam cake; Drive circuit board is housed in lamp socket; The led light source that is connected with the drive circuit board circuit is housed on the panel of going to the bottom of lamp socket and is packaged with transparent (glass) lampshade, be provided with ore deposit cable connecting hole at the place, two side of lamp socket.
The technical solution of the utility model also is: lamp socket go to the bottom that one is packaged with the direct-cooling type radiator between panel and Transparent lamp shade, light source heat radiation and power supply heat sinking are separated.
Compared with prior art; The described flame-proof mine led light source of the utility model tunnel light fixture has high, the characteristics such as energy consumption is low, long service life, projection distance is far away, the big thermal diffusivity of illumination is good of light efficiency; Simultaneously this light fixture have also that volume is little, in light weight, shock-resistant, vibration resistance etc. point, place and environment temperature≤+ 40 ℃ of gas and coal dust explosion hazard, the place work of relative air humidity≤95% (+25 ℃) can be arranged under coal mine.The utility model adopts great power LED cold light source (illuminance intense light source), and average life, luminous flux reached 40Lm greater than 50000 hours; Exceed more than 5 times than incandescent lamp; Its light is soft, illumination is high, and mine lamp illumination reaches as high as 1300Lx, is higher than the requirement of national standard illumination 800Lx; This lamp light source adopts constant current driving device, and the operating current of LED is not changed with battery terminal voltage, thereby the illumination of king light in specified light a lamp hour is remained unchanged; Harmful substances such as in addition, led light source has no radiation pollution, and is not mercurous have guaranteed the safe and reliable operation of tunnel lamp, thereby the utility model is a kind of ideal green environmental protection flame-proof type tunnel lamp, meet the state basic policy requirement of energy-saving and emission-reduction.
