Types of mining lamps and requirements for use

Source of information:yaorong  date:2017-08-22  

The industrial lamp is a general term for the lamps and lanterns used in the production areas of factories, mines, warehouses and highhouses. In addition to the various lighting lamps used in the usual environment, there are explosion-proof lamps and anti-corrosion light.

According to the lighting function can be divided into two kinds of general lighting and local lighting. General lighting general lighting is usually evenly arranged in the workplace above or on the side wall, lighting the entire face, the need to use more powerful incandescent, halogen, high-intensity gas discharge lamp or a large number of fluorescent lamps, of course , There are more energy-efficient high-power LED mining lamps, etc., the vast majority of mining lamps are such. General lighting on the distribution of light has a higher demand, widely used direct lighting and semi-direct lighting type of two types of light distribution, especially the latter. A part of the semi-direct lighting type illuminates the ceiling, which increases the ceiling brightness and creates a more comfortable and brighter environment. Local lighting local lighting is a kind of work to improve the illumination of the lamp. Its role can be based on the general lighting to strengthen, add lighting, it can be in some usually do not need lighting places (such as equipment maintenance, maintenance sites) as a temporary lighting. Most of their light distribution is not strictly regulated. Local lighting is usually installed near the work area to use the safety extra low voltage (≤ 50V, AC rms) of incandescent, halogen light for the light source. There are (portable) line lights, hanging lights, table lamp, machine work lights and so on. In some tall buildings, sometimes use the cast light for local lighting. Mining lamps can be divided into traditional light source according to light source (such as sodium lamp, mercury lamp, etc.) and LED mining lamp. Compared to the traditional mining lamp LED mining lamp has a great advantage: 1 LED mining lamp refers to the high RA> 702 LED mining lamp light efficiency, more energy efficient, the equivalent of 100W LED mining lamp can replace the traditional 250W traditional mining lamp. 3 traditional light source has the shortcomings of high temperature lamps, lighting temperature up to 200-300 degrees. The LED itself is a cold light source, low temperature lamps, more secure, are cold drive. 4 LED mining lamp in the constant innovation, the latest type of fin-type radiator mining lamp more reasonable radiator design, greatly reducing the weight of mining lamps, so that the overall weight of 80W LED mining lamp down to 4KG below, and Perfect solution 80-300W LED mining lamp cooling problem.


Application requirements for mining lamps

In order to meet the visual needs of different production operations and lighting installation conditions, the reflector of the mining lamp should be able to produce a wide range of light distribution. Surface painted, glazed to make white, and with aluminum, glass mirror, prism glass and other materials made of the reflector, can get a wide light distribution, suitable for large area, the face vertical or close to the vertical workplace The For tall buildings and places where there is a need for a single machine, a reflector made of prismatic glass, mirror glass, and polished aluminum can be used to obtain a narrow beam distribution.

In the dusty, humid and other environmental conditions in the poor long-term, reliable work, mining lamps in the structural design, shell and reflector, etc. have special requirements. Dusty environment should be used in closed lighting or uplift convection lamps (see photo); humid environment should pay attention to the shell of the closed and reflector surface treatment; general indoor commonly used open lighting, the use of enamel surface reflection Aluminum reflector with a thicker or coated oxide film on the surface of the oxide film; taking into account the unavoidable vibration in the production site, the fixed light source should be used for the release of the lamp holder.

There are a variety of fixed ways. General lighting has a ceiling, embedded, hoisting (using straight pipe or chain) and suction wall and other forms. The movable local lighting is equipped with a corresponding hook, handle, clip, etc .; fixed local lighting is generally fixed with a screw or fixing mechanism on the working machine.
