As a commercial lamp, industrial and mining lamp is widely used. Its main advantage is local lighting, which is a kind of lamp to improve the illumination of a certain working position. Its function can be to strengthen and supplement lighting on the basis of general lighting, or it can be used as temporary lighting in places that do not need lighting at ordinary times (such as equipment maintenance places). There are no strict regulations on their light distribution. Local lamps are usually installed near the working area, with incandescent lamps and tungsten halogen lamps with safety extra low voltage (< 50V, AC effective value) as the light source. There are (portable) running lights, hanging lights, work table lights, machine tool work lights, etc. In some large factory buildings, projection lamps are sometimes used for local lighting.
According to the light source, industrial and mining lamps can be divided into traditional light source industrial and mining lamps (such as sodium lamp industrial and mining lamp, mercury lamp industrial and mining lamp, etc.) and led industrial and mining lamps. Compared with the traditional industrial and mining lights, led industrial and mining lights have great advantages:
1 led industrial and mining lamp indicator height RA > 70
2 led industrial and mining lights are more efficient and energy-saving, equivalent to 100W led industrial and mining lights can replace the traditional 250W industrial and mining lights.
The traditional light source has the disadvantage of high lamp temperature, which can reach 200-300 ℃. The LED itself is a cold light source, the lamp temperature is low, more safe, belongs to the cold drive.
In the continuous innovation of led industrial and mining lights, the latest fin type radiator industrial and mining lights have more reasonable radiator design, greatly reducing the weight of industrial and mining lights, reducing the overall weight of 80W led industrial and mining lights to below 4kg, and perfectly solving the heat dissipation problem of 80-300W led industrial and mining lights.
