New technologies, new materials and new technologies are constantly applied to the design of high-power LED light sources, laying a solid foundation for the design of high-power LED lamps and lanterns. In LED lamps and lanterns, the important components are three parts: drive, light source and heat dissipation.
The power supply is a high quality, high efficiency and high stability LED water proof constant current driving power specially designed for LED. With quick start, wide compatible load range and complete protection function, the import voltage AC85-265V, high precision constant current control, high efficiency and reliable performance, and the appearance structure of all aluminum will make LED lamps more safe and stable.
2. Light source selection
At present, high power LED light sources are more famous brands: CREE, OSRAM, NICHIA, Lumileds (the earliest LED), in addition, the Taiwan manufacturer's crystal element, Addison and the domestic packaging plant Shenzhen Wan run, Zhuhai Ruifeng, Jiangxi LIAN and so on are also more popular brand.
3. Heat dissipation design
In high power LED, heat dissipation is a big problem. For example, if the 1 10W white light LED has the photoelectric conversion efficiency of 20%, the electrical energy of the 8W is converted into thermal energy. If no heat dissipation is used, the core temperature of the high power LED will rise rapidly, and when its junction temperature (TJ) rises above the permissible temperature of * * (generally 150), the high power LED will be damaged by overheating. Therefore, the heat dissipation design is also the most important content. The following are the two aspects of aluminum substrate and radiator to explore the heat dissipation design.
3-1, substrate selection
In the application of LED products, it is usually necessary to assemble multiple LED light sources on a circuit substrate. In addition to the role of the structure of the LED module, the circuit board, on the other hand, has to play the role of heat dissipation as the output power of the LED becomes higher and higher, so as to send out the heat generated by the LED crystal. Therefore, the material selection must take into account the requirements of the structural strength and heat dissipation. For substrates, we compare FR4, ceramic substrate and MCPCB. respectively.
(1) the thermal conductivity of FR4 is about 0.36W/m. K, which can not meet the heat dissipation requirements of high power LED lighting.
(2) the thermal conductivity of Ceramic is greater than 80W/m. K, which is expensive, poor workability and can not be used in large area.
(3) MCPCB thermal conductivity is greater than 2.0W/m. K, moderate price, strong processing, mature technology, mass production.
3-2 radiator design
The function of the radiator is to absorb the heat transferred from the substrate or chip, and then spread to the external environment to ensure the normal temperature of the LED chip. Most of the radiators are carefully designed for natural convection and forced convection. That is, the active radiator and the passive radiator.
4, the characteristics of LED industrial and mining lamps:
4-1, LED industrial and mining lamps use a single large power LED lamp as light source, using a unique multi chip set single mode group light source design, selected imported high brightness semiconductor wafers, with high thermal conductivity, light fading, pure color, no heavy shadow and other characteristics;
4-2, the unique design of heat dissipating body, combined with the electric box, effectively diffusion of heat, thus reducing the temperature in the lamp, effectively ensuring the life of the light source and power.
4-3. The surface of the radiator is anodized and anti-corrosive, and the structure is compact and beautiful.
4-4, green environmental pollution, no lead, mercury and other pollution elements, no pollution to the environment.
4-5. The color display is good, the color of the object is more genuine, the various light and color can be selected. It can meet the needs of different environment, eliminate the depressing emotion caused by the high or low color temperature of traditional lamps and lanterns, make the vision feel comfortable and improve the work efficiency of people.
4-6. Using constant current and constant pressure control, the voltage wide is applied to overcome the power grid, noise pollution and light instability caused by the ballast, so as to avoid the stimulation and fatigue in the eye.
4-7, the decorative effect is good, the special surface treatment technology is adopted, the appearance is novel, the installation is simple, the disassembly is convenient, and the application scope is broad.

LED industrial and mining lights and driving power must be installed in an open space, which is conducive to heat dissipation.2., we must regularly clean up the LED industrial and mining lights and the dust of the driving power, so as to ensure good heat dissipation.The Shang hung lighting industrial and mining lamp is divided into three parts in the packaging box, the lamp body, lampshade and accessories (several screws, convex lens, fixed hanging ring).1, after taking out the items in the package, first check the items.2, fix the convex lens on the lamp body, pay attention to the hole position. When placing the correct position, the COB light source should be in the middle position of the convex lens, and the screw should be tightened.3. The lamp shade is fixed on the lamp body. For the sake of convenient operation, the lamp body can be inverted on the table first, and then the lamp shade is picked up to position the hole on the lamp body. Tighten with the screw!4. Hang the ring on the lamp body. The fixed hook is threaded and can be directly fasten on the lamp body.5. The assembly steps are completed. Next, the hanging rings of the LED industrial and mining lamps are aligned to the reserved hooks.6, the wiring of the remaining LED industrial and mining lights has been worked. Attention should be paid to the distinction between zero line and fire line. To ensure safety, please install by professional electricians.Generally speaking, the installation procedure of LED industrial and mining lamps is like this. After installation, remember the electricity detection.Shang Hong lighting

The power of LED industrial and mining lamp is only 20% of sodium lamp, equivalent to 100W's LED industry and mine. The lamp can replace the 500W sodium lamp, especially in line with the "green low carbon" proposed by the state.Knowing above, I believe that when you choose LED industrial and mining lights, you will take comprehensive consideration. Hangzhou Shang hung lighting serves you wholeheartedly.
Industrial and mining lamps are the full name of lamps used in the production area of factories and mines. The LED lamp is an important part of urban lighting, and it is gradually replacing the status of traditional industrial and mining lamps. The LED industrial and mining lamps are gradually beginning to permeate in the life. The effect of the unique LED light source is the dust of the traditional industrial and mining lights.Traditional industrial and mining lamps often use 250W and 400W metal halide lamps. The 360 degree luminescence of metal halide lamps and the large loss of light cause huge waste of energy. Therefore, the development of new high efficiency, energy-saving, long life, high color index, environmental protection of the LED industrial and mining lights for national industrial lighting energy saving is of great significance.LED industrial and mining lamps are used to replace the traditional industrial and mining lights. Why do you use the LED lamp to replace it? Because the LED light source has its unique advantages: energy saving, mercury free pollution, long life, fast response time and safety.Industrial and mining lamps can be divided into traditional light industrial and mining lamps and LED industrial and mining lamps according to the light source. Compared with traditional industrial and mining lamps, LED industrial and mining lamps and lanterns have great advantages:1 LED industrial and mining lights show high RA>702 the LED mine has higher efficiency and more energy saving. The equivalent of 100W's LED industrial and mining lamp can replace the traditional 250W lamp.3 the traditional light source has the disadvantage of high temperature of lamps and lanterns, and the temperature of lamps can reach 200-300 degrees. LED itself is a cold light source, lamps and lanterns are low and safer.4 LED industrial and mining lamps in the continuous innovation, * * type fin type radiator industrial and mineral lamps more reasonable radiator design, greatly reduced the weight of industrial and mining lamps and lanterns, the overall weight of the 80W LED industrial and mining lamps down to below 4KG, and can solve the 280-300W LED industrial and mining lights heat dissipation.Compared with the brightness of 100 watt LED, the brightness of the industrial halogen lamp is equal to 250 watts, and the average illumination does not weaken.Compared with energy saving, with 100 lamps and lanterns as an example, the average daily use of 10 hours, electricity charges 1 yuan / degree, LED industrial and mining lamps daily electricity 100 yuan.The electric cost of the gold halogen lamp is 250 yuan per day. Replacing the 250 Watt gold halide lamp with 100 watt LED industrial and mining lamps can save electricity by 4500 yuan per month, saving electricity by 54750 yuan per year.The life span of the life gold halogen lamp is 8000 hours, the LED lamp can reach 30 thousand hours - the equivalent of 10 hours a day for the light. It can be used for 8 years, greatly reducing the cost of changing the light. The cost performance is really high.It contains mercury in ordinary lamps, including gold halogen lamps, and the mercury contained in dozens of gold halogen lamps can pollute the whole of West Lake, and the LED industrial and mining lamps have no mercury, xenon and other pollution elements, which are typical green light sources.Compared with the healthy gold halogen lamp, the light will produce ultraviolet and infrared light, the heat is large, the air is dry, and the LED lamp does not radiate. It protects the eyes and health of the body.Therefore, the emergence of LED industrial and mining lamps has gradually replaced the traditional industrial and mining lamps.Shang Hong lighting
