Abstract
The utility model relates to an electronic miner lamp for underground mining workers use. The utility model is characterized in that: a shell is provided with a storage battery inside and a spotlight cover at the front port; the spotlight cover is positioned with a transparent cover and a high brightness white LED inside; the pin of the LED is arranged on a circuit board inside the shell body and a storage battery is electrically connected with the circuit board. By adopting the white LED as the light emitting component, the utility model features lower electric consumption and longer service life and can use a lithium battery or a nickel hydrogen battery as the power source. The miner lamp has light weight and small volume, thus being able to be fixed on the helmet cap by a hook to realize convenient in carrying along. The utility model will not ignite coal mine gas in particular under the condition that the miner lamp is damaged accidentally, thus greatly enhancing the safety performance.
Description
Technical field
The utility model relates to the mine lamp that a kind of down-hole cutter uses, specifically a kind of Subminiature electronic mine lamp.
Technical background
Nowadays the used mine lamp of coal miner still is traditional lead-acid accumulator Explosion-proof miner's lamp.Its structure is that the front port at housing is connected to the optically focused lampshade, splendid attire battery in the housing, and the prosopyle of optically focused lampshade is connected to translucent cover, in the optically focused lampshade incandescent lamp bulb is housed, and this bulb is electrically connected with battery and switch.This mine lamp weight is about about 1.5kg, and carrying and wearing all has inconvenience.In addition, the service life of bulb is shorter, and Chang Yin extinguishes and delays work.Particularly security performance is relatively poor, because the luminance temperature of tungsten filament is far above the ignition temperature of gas in the bulb, in case cloche and bulb fragmentation, very easily explosion caused accident.According to statistics, the mine safety accidents that causes because of mine lamp accounts for more than 10% of sum.
The utility model content
The purpose of this utility model just provides a kind of Subminiature electronic mine lamp, to improve the service life and the security performance of mine lamp, reduces accident potential, ensures production safety.
The utility model is achieved in that the front port at housing is connected to the optically focused lampshade, splendid attire battery in the housing, the prosopyle of optically focused lampshade is connected to translucent cover, in the optically focused lampshade, be provided with the high brightness white light-emitting diode, the pin of light emitting diode is connected on the circuit board that is positioned at housing, and battery is electrically connected with circuit board.
As light-emitting component, its brightness is higher than the common osram lamp that uses in the existing mine lamp to the utility model with the white light-emitting diode of super brightness.Because light emitting diode is the cold light source electronic component, power consumption is low, and service life can be more than 10,000 hours.In addition because the operating voltage of light emitting diode is direct current 3V, so but lithium battery in the existing mobile phone of adapted or Ni-MH battery etc. as power supply.Like this, the weight of whole mine lamp just can be reduced to below 300 grams, and volume also can obviously dwindle, and directly hook is fixed on the miner's safety helmet, has reached portable purpose.Particularly when mine lamp is unexpected damaged, the light emitting diode coal mine gas that can not ignite, therefore the security performance of mine lamp increases substantially, and has avoided the security incident that causes thus.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the circuit theory diagrams of a kind of custom circuit of adopting of the utility model.
The specific embodiment
As shown in Figure 1, lithium battery 1 is housed in housing 4, lithium battery can have 1 to 2, decides as required.Be connected to circuit board 5 in housing 4, the circuit on the circuit board 5 is electrically connected with lithium battery 1.At the front port of the housing 4 parabolical optically focused lampshade 2 that spins, the lampshade prosopyle transparent organic glass cover 9 that spins.Be provided with high brightness white light-emitting diode 3 on the focus point in optically focused lampshade 2, its pin passes the front port of housing 4, is connected on the circuit board 5 insulation of filming of the exposed part of pin.
Can finish the charging task for lithium battery 1 in the mine lamp need not be taken out in housing, built-in safe charging joint 7 also is housed on housing 4.External special charger adopts the roughly the same mode of cell-phone charging, when inserting in the housing 4 in the joint end, can join with safe charging joint 7, finishes charging work.A kind of knob safety switch 8 of in housing 4, preferably packing into.The knob of knob safety switch is located at outside the housing 4, and the column type switch body and after safety switch 8 is rotating through different positions, can be electrically connected with lithium battery 1 and safe charging joint 7 respectively in housing.Be that safety switch 8 can be provided with third gear, two open and close shelves that gear is a power supply wherein, the 3rd gear opened shelves for charging.
For guaranteeing the brightness of mine lamp, 2-3 high brightness white light-emitting diode 3 can be set in optically focused lampshade 2.In mine lamp shown in Figure 1, two white light-emitting diodes are housed.
Between the interface of optically focused lampshade 2 and housing 4, also can be provided with insulating plug 6, with battery 1 and the circuit board 5 in the isolated housing 4.At this moment, the pin of white light-emitting diode 3 can pass insulating plug 6, joins with circuit board 5.Be provided with hook 10 at the rear portion of housing 4, in order to the miner's safety helmet hook is fixed.
A kind of adoptable circuit structure of this Subminiature electronic mine lamp as shown in Figure 2, IC chip LM wherein
2791Be a kind of voltage-multiplying type charge pump converter, the current source of two white light-emitting diodes can be provided.After the K switch closure, supply voltage is through diode D
1To capacitor C
3Charging is started working internal oscillator, two white luminous pipe LED state that can maintaining lights.The operating current of luminous tube and resistance R
1Relevant.
