Why is the high quality LED lamp slightly expensive?
Do you like quality led lamp but competitive / low prices? YES. I believe that everybody say yes. We all known, the biggest advantage of LED lights is energy saving and durability, energy-saving is led chip essential characteristics, durability is mainly light decay control.
The key factors that affect light decay: Firstly led chip, high quality chip its light decay is small but price high, low quality chip its light decay is large but price low. Secondly led driver, LED lamp light-emitting diode chip fever is very sensitive by constant current drive. It must be constant current drive to control the chip heating, control the heat to control the light decay.Thirdly is the packaging process, especially high heat requirements, production process is also very important.
The above three factors achieved the quality of LED, but also decided its high price, the so-called "high quality high price, low price high light decline."
