Six characteristics of LED high bay light
2022-03-11
High Bay Lights are an important part of urban industrial lighting. Traditional high bay lights often use 250W and 400W metal halide lamps. Metal halide lamps emit light at 360 degrees, and the shortcomings of large light loss cause a huge waste of energy. LED High Bay Light has gradually entered people's field of vision with the advantages of directional light emission, low power consumption, good driving characteristics, fast response speed, high shock resistance, long service life, and green environmental protection. LED High Bay light has the following characteristics: 1. Environmental protection, energy saving, normal service life of lamps; more than 30,000 hours. 2. On the premise of the same brightness, the 70W LED high bay light saves 60% of electricity than the 175W high pressure sodium lamp. 3. For the light source part of the high bay light, the light source adopts the chip of the American company, which has high efficiency, low light decay and large current margin. The rated current of the chip is 700mA, but only 310mA is actually used. The thermal resistance is small, and the operating temperature of the chip is low. The actual junction temperature is less than or equal to 50℃, thus ensuring the stability and long life of the work. 4. About 80% of the energy in the LED lamp in the heat dissipation part of the high bay lamp is converted into heat energy. Therefore, with the increase of the power and integration of the LED, the heat flux density of the LED increases rapidly, and the heat dissipation problem becomes more and more serious. . Excessive LED junction temperature not only makes the life of the LED attenuate sharply, but also has a serious or even fatal impact on many performance parameters such as the peak wavelength, optical power, and luminous flux of the LED. However, the natural convection heat dissipation, fan forced heat dissipation and various heat pipe heat dissipation methods currently used have very limited cooling capacity, and it is difficult to obtain heat from the surface of the high-heat-intensity LED wick in time and dissipate heat to the outside, so that the temperature is reduced to an ideal range. . 5. The lamp body part of the high bay lamp: Super cooling capacity: the heat flux density of heat extraction has reached 400W/cm2, its capacity is 1000 times higher than that of water cooling, and about 100 times higher than that of heat pipes. Low LED chip temperature: LED chip operating temperature can be lower than 60 ℃. Light weight and small size: the weight is less than 25% of the existing radiator, and the volume can be reduced to less than 20%. No power consumption cooling; passive cooling, no fan or water pump, no cooling energy consumption. 6. Application occasions of high bay lights, suitable for shipyards, mines, workshops, workshops, warehouses, highway toll stations, gas stations, large supermarkets, exhibition halls, gymnasiums and other places that require industrial and mining lighting.
