Energy saving has always been a global concern. It accounts for around 19-20% of total global energy consumption. If you use LED purification lights, you can give full play to the advantages of power saving and longevity. Therefore, in recent years, the LED purification lamp market, like bamboo shoots in the spring rain, has rapidly become the world's leading industrial, commercial space lighting, street lamps, lamps, plants and other kinds of applications, rather than various traditional lighting applications. The government promotes carbon reduction policies in the direction of energy conservation.
However, what about the problem of low lamp life caused by the use of electrolytic capacitors in LED purification lamps? This is a controversial and controversial issue. Eucalyptus for LED purification lamps is generally divided into isolation and non-isolation. In the application of prefabricated lamps in the mains, due to concerns about safety issues, most customers choose isolated LED drive power and the production of LED drive power market is almost all with electrolytic capacitors In the design, we have been focusing on the development and quality continuity of switching power supply products, especially the electrolytic capacitors that play a role in LED purification lamps and performance life in further research.
Life factors of LED purification lamps
The key factor affecting the life of LED purification lamps is not only the electrolytic capacitors used in the light source and driving power supply, but also directly related to temperature. Current commercial lighting signs have a lifespan of less than 15,000 hours and more than 50,000 hours. According to the data of LED purification lamp factory, the average life of general high-power LED is about 50,000 hours or tm-21 based on LM-80 test results. The inset shows Cree's life test and calculation examples of LEDs. The life of the LED driver depends on the grade and temperature of the electrolytic capacitors used in the design, and is usually not less than the life of the LED, which is a reasonable design choice.
The life of LED purification lamp
Junshuo Lighting verifies that LED purification lamps are always recommended for tests and calculations based on the electrolytic capacitors provided by an internationally renowned manufacturer based on the hlg-150h-24 model as an example, with electrolytic capacitors 10000 hours @ 105 C level the highest output capacitance Due to its efficiency as high as 93%, the test environment temperature is 60°C, and the temperature rise of electrolytic capacitors with a low temperature of no more than 80°C is as high as more than 70,000 hours. The actual calculation of product life, if used at 50°C ambient temperature, Life expectancy is estimated to double. Therefore, the design of the electrolytic capacitor of the LED driving power supply is actually no problem for the life of the lighting effect. It is very important in the procurement and supply of lamps. The high-efficiency circuit design of the configuration should be used and some LED purification lamps adopt high-quality The design of electrolytic capacitors pushes the basic solution to the lifespan of the lamp road.
