According to the Ming function can be divided into general lighting and local lighting two kinds.
General light
General lighting is normally arranged on average in the upper part of the working area or on the side wall, lighting the whole working face, the need to use larger power incandescent lamp, halogen tungsten lamp, high intensity gas discharge lamp or a larger number of fluorescent lamps, of course, there are more energy-saving high power LED mining lamp, mining lamps belong to the vast majority of departments. General lighting has higher requirements for the distribution of light, the use of direct lighting and semi-direct lighting two types of light distribution, especially the latter. The light that one department in half direct illume sends up illuminates ceiling, can increase ceiling brightness, create a more comfortable, brighter environment.
Local light
The local floodlight is a kind of lamps and lanterns that improve the illumination of a certain working part. Its function can be on the basis of general lighting to strengthen, add illume, also can be in a few do not need illume at ordinary times place (be like equipment inspect, maintain place) regard as temporary illume. The distribution of their light is not strictly defined. Local lighting is usually installed around the work area, with the use of safe extra-low voltage (≤50V, ac effective value) incandescent lamp, halogen tungsten lamp as the light source. There are (portable) line lamp, hanging lamp, working desk lamp, machine tool working lamp, etc. In a few tall workshop, also use cast light lamp to make local illume sometimes.
Mine lamp can be divided into traditional light source mine lamp (such as sodium lamp mine lamp, mercury lamp mine lamp, etc.) and LED mine lamp according to the light source. Compared with traditional mining lamp, LED mining lamp has a great advantage:
1 LED industrial and mining lamp display height RA>70
2 LED mine lighting efficiency is high, more energy saving, matching 100W LED mine lamp can replace the traditional 250W mine lamp.
3. Traditional light sources have the disadvantage of high lamp temperature, lamp temperature can reach 200-300 degrees. The LED itself is a cold light source, the lamp temperature is low, more safe, belong to the cold drive.
4 LED mining lamp in the continuous innovation, the latest finned radiator mining lamp more reasonable radiator design, greatly reduce the weight of mining lamps, so that the overall weight of 80W LED mining lamp down to less than 4KG, and can perfectly solve the problem of 80-300w LED mining lamp cooling.
