How To Choose A Good LED High Bay Light?

Mar. 05, 2019

LED High Bay Lights are long lasting because they do not cause filaments to blow. The LED does not stop working directly, but it gradually degrades over time. Generally, LEDs can be used for more than 50,000 hours, and their luminous intensity will gradually drop from the nominal value to about 70%. The main reasons for the LED life are the following three components: light source, power supply and housing.

Light source

LED chip quality is an important reason for life, and the design and materials of the chip can affect the life of the LED. LED packaging technology is also an important reason for the LED life, a reliable packaging manufacturer has a great relationship to LED life.

2. LED Flood Light power supply design

Because the discreteness of the LED is extremely strong, the voltage drop, the wavelength, the color of the light, and the height are very different. Only the LEDs with the above-mentioned several indicators can be used in parallel, and the current with the reduced voltage is large, and the current with a high voltage drop is small. The color and height are uneven, and the life of the current is shortened. The life of the power supply itself is also an important reason. Generally, the electrolytic capacitor has an 8000-hour life at 105 °C, 15,000 hours at 40-60 °C, and 30,000 hours without electrolytic capacitors.

3. Design of heat dissipation

Heat dissipation is one of the important reasons that affect the life of LEDs. LEDs need to be driven by current. Only about 15% of the input LED energy is converted into light, and most (about 85%) are converted into heat due to inefficiency. The ambient temperature is very important, and the ambient temperature can affect the temperature of the LED lamp from 5 to 20 degrees.
