Description

MINER'S LAMP
Field of Application
The utility model refers to a Miner's lamp, which finds application in the mining industry and tunnel construction.
Former State of the Equipment
We are familiar with a Miner's lamp whose battery is separated from the lighting fitting. The battery is carried on a belt, in a pocket or around the neck and the lighting fitting is attached to the helmet. The lighting fitting has a filament electric light bulb. The two parts of the Miner's lamp are connected with a cable /1/.
A different type of Miner's lamp is known as well. It also consists of two separate parts, battery and lighting fitting, connected with a cable, but the lighting fitting has two filament electric light bulbs. This type of Miner's lamp provides illumination at two levels. Its advantage in comparison with the previously described lamp is that if the fast electric light bulb burns out, the second one can still be used 121,
So far Miner's lamps which use light-emitting diodes as a source of light are not known.
The disadvantages of the currently existing Miner's lamps are that they consist of two parts connected with a cable, which is inconvenient for work. These Miners' lamps are heavy, have a short duration and burn out suddenly so the life of the filament electric light bulbs gets shorter every time they're switched on. The purpose of the utility model is to create a Miner's lamp, which is light, convenient for work, long-lasting, does not burn out suddenly, economical of electrical energy and characterized by minimal heat loss. Its battery and lighting fitting are combined into a compact unit, which is easily attached to the helmet.
Technical Details of the Utility Model
The utility model offers a Miner's lamp that uses an energy saving lamp with light- emitting diodes and a battery built into its body. The number of the light-emitting diodes determines the intensity of the light flux. The battery and the lighting fitting are combined into a compact unit, which is easily attached to the helmet.
The task is performed by a Miner's lamp, which includes a body with a reflector, lamp socket, and a two-level switch attached to it A resistor, charging pins and a plate, which attaches to the helmet, are connected with the two-level switch for an economical operation mode. A diode is connected with one of the pins to avoid a short circuit.
An energy saving lamp with light-emitting diodes, which is installed in the lamp socket, is connected through cables with the battery and the two-level switch.
The advantages of the utility model are that the Miner's lamp does not burn out suddenly arid if one of the light-emitting diodes stops operating, this does not impede the operation of the others. The Miner's lamp is shock, water and dust resistant. It is light and convenient, and its operation time span is more than 22 hours between two chargings. It also saves electrical energy due to the minimal heat loss.
Short description of the enclosed figures
An example of the utility model implementation is shown at the enclosed figures:
Figure 1 - outline of the Miner's lamp
Figure 2 and figure 3 - outward appearance of the Miner's lamp The utility model can be illustrated by an example of the following implementation: Example 1. The Miner's lamp in accordance with the utility model includes body 4, with a firmly attached to it reflector 1, lamp socket 6, two-level on-and-off switch 3. A resistor 11 is connected with the two-level switch for an economical operation mode. The Miner's lamp also includes charging pins 5 and a plate 10, which attaches to the helmet. A diode 9 is connected with one of the charging phis 5 to avoid a short circuit. An energy saving lamp with light-emitting diodes 2 are installed into the lamp socket 6 and is connected through cables 7 to the battery 8 and the two-level switch 3.
The Miner's lamp in accordance with the utility model functions in the following way: By means of the two-level on-and-off switch 3 of the Miner's lamp the electrical circuit is closed and an electrical current begins to flow from the battery 8 through the cables 7, the lamp socket 6 and the energy saving lamp with light-emitting diodes 2. The two-level switch 3 allows the Miner's lamp to operate at two degrees of intensity. At the first position of the switch the energy saving lamp with light emitting diodes 2 is connected in series to a resistor 11, which decreases the intensity of the electrical current flowing through it. In this way an economy of electrical energy is achieved at the expense of the intensity of the light flux and a longer operation time span of the miner's lamp between two chargings. At the second position of the two-level switch 3 the energy saving lamp with light emitting diodes 2 is switched on directly to the power supply. The battery 8 is charged through the charging pins 5 and the diode 9 which protects the battery from a reverse turning on of the charging device and a short circuit between the two charging pins.
The Miner's lamp operation time span is more than 22 hours between two chargings.
