A LED light bulb adopts ceramic lining wings, and with a glass stem, it is high than the cost of plastic and metal products.
Second, each model of the LED light bulb is equipped with a small printed circuit boards, greatly improve the reliability of the leds coefficient, however, under the condition of the hot work, the service life of electrolytic capacitors can have how long? The led driver IC is different is the LED light bulb one of the biggest differences. Have a LED light bulb adopted four IC, 40 resistance and 16 capacitance, plus a transformer and multiple diode, can be used in the LED light bulb dimmer.
Again, the led 40 WCFL photosynthetic efficiency and 50 lm/W ~ 60 in lm/W, LED light bulb of 40 WCFL of photosynthetic efficiency, and CFL light efficiency is usually 560 lm/W; Price a few dollars’ worth of CFL bulbs can be used for eight years. 1 LED light bulb and save electric energy, equivalent to 25 years in the future to buy 2 or 3 CFL bulbs. Fortunately, CFL bulb with 2 or 4 a set packing. However, for CFL, we avoid the mercury pollution at the expense of the energy consumption. And lamps and lanterns of led ball bubble has double attraction: first it without preheating time, can light up immediately; Secondly it does not contain mercury, led the low toxicity of rare earth elements, and the quantity of rare earth elements and rarely used.
Over time, the price of the LED light bulb will decline gradually, it will become the CFL substitute cleaner, safer, has a longer service life and can be expected. In addition, we also can expect led ball bubble lamp, all kinds of new features; In terms of these, LED light bulb on indoor lighting potential still can continue to grow.
