LED High Bay Lights

LED High Bay Light is a white light with bright LED as a light source, the use of passive cooling structure thermally efficient, suitable for workshop, factory, warehouse, highway toll stations, gas stations, supermarkets, exhibition hall, stadium, construction sites, mines and other places of lighting required. LED high bay light with respect to the current mining lamps use more incandescent, halogen, high intensity discharge lamps or fluorescent lamps have many advantages, the traditional mining lamps, light which they use high pressure mercury lamp or a metal halide high-power was light and a halogen lamp, etc., mining lamps made of relatively bulky, power consumption, high maintenance costs, environmental pollution, lighting effects in color changes were unsatisfactory. The traditional mining lamp for general lighting is the use of lighting, including ordinary mercury lamps, metal halide, fluorescent lamps, general lighting is AC voltage, operating frequency under 50Hz light, the resulting strobe easily cause eye fatigue; problems exist filament preheating startup, can not achieve quick start; and some general mining lamps using liquid mercury (mercury) and other harmful gases, is not conducive to environmental protection and working conditions.
In the modern fast-growing LED lighting, because LED lights energy-saving, long life and easy maintenance features people of all ages, more and more LED lighting will be applied to each part of the production and life, in factories, workshops, mines the extensive use of LED mining lamp. LED industrial lighting efficiency, more energy-efficient, equivalent to a 100W LED mining lamp can replace traditional 250W traditional mining lamp; traditional light fixtures have the disadvantage of high temperature, lighting temperature up to 200-300 degrees, while the LED itself is cold light, lamp temperature is low, more secure. Compared with the traditional mining lamp LED mining lamp with a long life, high luminous efficiency and low power consumption characteristics, energy saving effect is remarkable. Since workplace illumination needs work wattage is generally between tens of watts to several hundred watts. LED high bay light color is good, the color rendering of the kind more real, all kinds of light color options to meet the needs of different environments, eliminating the traditional lamp color temperature depression caused by low mood or make visual comfort to improve people’s working efficiency.
LED mining lamp housing includes a thermally conductive heat sink and the PCB, heat sink and the PCB is located inside the housing of the thermal conductivity, PCB board is provided with LED, LED is provided with a lens, LED light out through the lens, LED light source or the use of an integrated package COB package source, astigmatism lampshade with aluminum die casting, diffusers which are coated with a reflective material, so that high-power integrated light lamp beads, ground illumination equalization. Fin radiator die cast aluminum alloy, the middle is a hollow cylindrical shape and is surrounded by 24 fin spacing is equal, seamless, integral with each other, both ends of a mounting fin heat sink and power supply diffusers mounting holes chamber. Power supply room for the aluminum hollow cylindrical, hollow cylindrical wall surrounding a uniform distribution of 12 hollow vents for the whole lamp body, provides a good convection structure, excellent heat dissipation in the rear chamber has the power cord into the AC input line hole.
LED mining lamp operation is stable, the quality is good or bad, is critical heat lamp body itself, from the very nature of high-power LED lighting, LED chips are characterized by an extremely high heat in a very small volume, while the LED itself the heat capacity is small, so must be the fastest speed to the heat conduction out, otherwise you will have a very high junction temperatures, which seriously affect the life. Common LED mining lamp shapes are basically using sunflowers aluminum radiator heat treatment done, the structure of the basic material are sunflowers radiator install a chip connected to the other end of the power supply box, power supply box is installed inside the drive power. The heat source is conducted to the radiator, radiator fins surrounding air through natural convection of heat into the air, this convection cooling methods require good heat flow channel; its principle is, after working heat source, heat to the heat sink, to increase the contact area with the air, an appropriate array of radiator fins around the central axis, the radiator temperature will heat the air around the fin, begins to rise surface air is heated, a negative pressure is formed around the fins attract bottom of the radiator cold air coming up, coming up cold air is then heated to rise, a negative pressure and cold air coming up, so the cycle, thus requiring a good air convection radiator passages to facilitate hot air timely discharge, cold replenish.
LED high bay light application in the mining environment in general, this application scenario of LED high bay light dust and insulation are higher, there is a special explosion-proof lamps used in the environment and anti-corrosion lights. Mining lamp in accordance with the invention functions can be divided into general lighting and local lighting two categories: general lighting lamps are usually arranged uniformly on the work site above or the side walls, lighting the entire working area, you need to use high-power LED high bay light; partial lighting It is a way to improve a work site illumination lamps. The role of mining lamps is based on the strengthening of general lighting, supplemental lighting, it can be in some of the usual places of lighting is not required for temporary lighting.
