Review of mine luminaires

APPLICATION OF MINE LUMINAIRE

The luminaires are approved as personal luminaires of workers for illumination at the areas with an explosion risk and they fulfil requirements for the devices classified in the group No. I. Luminaire T1005.01A is approved for M2 category of environment and luminaire T1005.01AM1 is approved for M1 category of environment according to the regulation No. 94/9/ES. The luminaires can be used for workers of all professions in the underground coal mines working in this environment.

They are suitable for utilization even in the most demanding condition of coal mines because of their design. They are made from special plastic materials. NiMh accumulator is used as energy source. LEDs are used as light sources that secure sufficient lighting for the time of 14 hours minimum.

The device that secures an optimal charging of the accumulator at any operating conditions after the connection to 10-15 Vss voltage. Head part of the luminaire contains two main and two signal LEDs. The bottom main LED shines so-called “to the point”, it means by narrow beam of light to the big distance, while the upper LED shines so-called “to the area” by a wide beam of light. Red signal LED indicates charging and green signal LED indicates that the luminaire is ready for application completely.

APPLICATION:

The luminaire is approved as personal luminaire of workers for illumination at the areas with an explosion risk and it fulfils requirements for the devices classified in the group No. I., category M2 according to the Code No. 23/2003 Coll. It can be used by the workers of all professions in the underground mines working in this environment.

DESCRIPTIO:

Mine luminaire T1005.01 is suitable for application even in the most demanding conditions of the coal mines because of its design. It is even capable to work in water. It is made from special plastic materials. NiMh accumulator is used as energy source. LEDs with high illuminating power are used as light sources that secure sufficient lighting for the time of 14 hours minimum. The device that secures an optimal charging of the accumulator at any operating conditions after the connection to 10-15 Vss voltage is a part of luminaire control module. Green signal LED in the head part indicates charging by blinking and readiness of the luminaire for operation by permanent shining. The main LED shines so-called “to the point” and auxiliary LED shines so-called “to the area”.
