LED high bay light may replace energy-saving lamps?
How about replacing energy-saving lamps with LED high bay lights? Let's take a look at the differences between them and see why?
1. The power consumption of ordinary energy-saving lamps is relatively large, which is more than 3 times that of LED high bay lamps. In terms of energy saving and environmental protection, energy-saving lamps have not kept up with the period.
2. Ordinary energy-saving lamps contain mercury, and if the bulb is damaged, it will affect people's safety.
3. The life balance of ordinary energy-saving lamps is only 1 year, while LED high bay lamps can reach 5W hours.
4. Ordinary energy-saving lamps only emit white warm colors, while LED high bay lamps are all solid luminous bodies, solid cold light sources, and the luminous colors are rich and colorful, 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, easy dimming and so on..
In the near future, the advantages of LED high bay lamps will be greatly developed without shame, and they will gradually replace energy-saving lamps.
LED high bay light has the following six characteristics:
1. The normal service life of environmental protection and energy-saving lamps is more than 30,000 hours.
2. Under the same brightness, the 70W LED high bay light saves 60% of electricity compared to 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. Good heat dissipation plan, and solder is used for solid crystal. 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, so with the increase of the power and integration of the LED, the fever 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 and even fatal impact on the peak wavelength, optical power, luminous flux and many other functional parameters of the LED. However, the currently used natural convection heat dissipation, forced heat dissipation by electric fans and various heat pipe heat dissipation techniques have very limited cooling capabilities, and it is difficult to obtain heat from the surface of the high-intensity LED light bulb in time and dissipate heat to the outside, so that the temperature is lowered to the desired limit. .
5. The lamp body part of the high bay lamp:
The cooling ability is very strong: the heat flux density has reached 400W/cm2, its ability 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 as small as 20% or less.
No power consumption cooling; passive heat dissipation, no fan or water pump, no cooling energy consumption.
6. High bay lights are 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.
