Where are the obvious advantages of LED high bay lights?

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 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 lamps can reach 5W hours.
4. Ordinary energy-saving lamps emit only 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, led high bay lights, yellow, blue, etc.
5. LED high bay light is energy-saving and environmentally friendly, shockproof, waterproof, miniature, high brightness, easy dimming and other advantages...
It is not difficult to see that the advantages of LED high bay lamps will be greatly developed in the near future, slowly replacing energy-saving lamps.

LED high bay light has the following six characteristics:
First, environmental protection, energy saving, normal service life of lamps and lanterns, more than 30,000 hours.
Second, under 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 LED high bay 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. Solder, small thermal resistance, low operating temperature of the chip, the actual junction temperature is less than or equal to 50 ℃, thus ensuring the stability of the work and long life.
What are the classifications of commonly used electric light sources for LED high bay lights? All equipment that can convert other forms of energy into light energy to provide luminous flux are collectively referred to as light sources, and among them, electrical energy can be converted into light energy, thereby Equipment and appliances that provide luminous flux are called electric light sources. Commonly used electric light sources are: ① thermoluminescent electric light sources (such as incandescent lamps, tungsten halogen lamps, etc.), ② gas discharge luminous electric light sources (such as fluorescent lamps, mercury lamps, sodium lamps, Metal halide lamps, etc.), ③ solid luminescent electric light sources (such as LED and electroluminescent devices, etc.), among these three types of electric light sources, the luminous efficiency of various electric light sources is quite different, and thermoluminescent electric light sources such as incandescent light sources Lamp, it uses the Stephen-Boltzmann law: the higher the temperature of the object, the more energy it radiates.
This can be expressed by the formula E=μξT4, where E is the total radiation energy per unit area and unit time of the object at temperature T, μ is the Stephen-Boltzmann constant (μ=5.6697×10-12W/(cm2· K4)), ξ represents the specific emissivity, that is, the ratio of the surface radiation power of the object to the black body radiation power, T represents the absolute temperature of the object, the electric light source made by the principle of thermoluminescence is simple to manufacture and low cost, but the luminous efficiency is low, The rest of the energy is dissipated as heat.
