Could LED High Bay Lights Replace Energy-saving Lights?
According to research data, the energy consumption of most advanced LED high bay lights can be as low as one-twentieth of that of ordinary light bulbs, but the durability is 10 times and 100 times that of fluorescent lamps and incandescent lamps respectively, and the lighting effect is more stable. Now the whole world is calling for the use of LED high bay lights, but the price of LED high bay lights is much higher than that of ordinary energy-saving lamps. Why use LED high bay lights to replace energy-saving lamps? Let's take a look at the difference between them and see why?
Ⅰ. The difference between LED high bay lights and energy-saving lamps
1. The power consumption of ordinary energy-saving lamps is relatively large, which is more than 3 times that of LED high bay lights . In terms of energy saving and environmental protection, energy-saving lamps have not kept up with the times.
2. Ordinary energy-saving lamps contain mercury. If the bulb is damaged, it will affect people's safety.
3. The average lifespan of ordinary energy-saving lamps is only 1 year, while LED high bay lights can reach 5W hours.
4. Ordinary energy-saving lamps only emit white and warm colors, while LED high bay lights are all solid luminous bodies, solid cold light sources, and have colorful luminous colors, such as: white, yellow, blue, etc.
5. LED high bay light has the advantages of energy saving and environmental protection, shockproof, waterproof, miniature, high brightness and easy dimming.
It is not difficult to see that the advantages of LED high bay lights will be greatly developed in the near future, gradually replacing energy-saving lamps.
Ⅱ. LED high bay light has six characteristics
1. The normal service life of environmental protection and energy-saving 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. LED high bay light source part: The light source adopts imported chips, which have high efficiency, low light decay, and large current margin. The rated current of the chip is 700mA , but only 310mA is actually used. Good heat dissipation design, and soldering is used for crystal bonding. 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 of operation and long life.
4. Heat dissipation part of industrial and mining lamps: About 80% of the energy in LED lamps is converted into heat energy, so with the increase of LED power and integration, the heat flux density of LEDs 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:
(1) 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.
(2) Low LED chip temperature: LED chip operating temperature can be lower than 60 ℃. Light weight and small size: less than 25% of the weight of the existing radiator , the volume can be reduced by 20%.
(3) No power consumption cooling; passive heat dissipation, no fan or water pump, no cooling energy consumption.
6. Application of LED high bay light : 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.
