LED lamps and lanterns is really energy saving and long life, maybe we are wrong

Leds are now widely used in various fields, from traffic lights to car headlights, from the LCD back light to LED display, almost everywhere. As lighting device, in particular, are very popular with people, to replace incandescent lamp and fluorescent lamp. But the selling point of energy saving and long life LED lamps and lanterns, can actually deliver? The LED is light emitting diode ( 发光二极管) , is a common electronic devices, through composite release energy electrons and holes. Energy conservation is the most prominent feature of LED lights, its energy consumption is one over ten of the incandescent light bulb, is a quarter of the energy-saving lamps. Because of this, in this era of advocating energy conservation and environmental protection, LED lights by people. Businessmen often propaganda, however, said the service life of LED lights for ten years or 40000 hours, but I often heard within less than a year after purchase has been replaced. Due to the price of LED lights than incandescent lamp or fluorescent lamp is much higher, if in such a short time to replace it, even if deduct the cheaper electricity, is far from good. In fact the problem is out on the LED lamps and lanterns, heat capacity. Although leds luminous device for a very long life expectancy, but the heat lamp holder and circuit board design, the performance is good and bad are intermingled. To convert alternating current into direct current, the LED lamp circuit boards need to be equipped with electrolytic capacitor, electrolytic capacitor is similar to the structure of the battery, so prone to failure at high temperature. Especially for the bulb type LED, heat savings more easily in the socket components, causing malfunction. Even if the life of the LED itself is very long, but if the circuit board component fault, not electricity, also won't shine. On the LED lamps and lanterns of heat dissipation is an interesting phenomenon, if the LED heat dissipation body temperature is not high, does not mean that the cooling control well, because there is no conduction may be internal heat. If the LED lamps and lanterns of the cooling body temperature is high, also cannot treat STH lightly, because the internal temperature of the LED lights may be higher. Heat dissipation has become influence LED lights to choose and use the big problem. As a solution, we'd better choose to have heat performance of LED lamps and lanterns, though this will further raising cost, but after all, can guarantee a long service life, realize the cost sharing, in the long run, it will cost less than using common lamps and lanterns or without heat performance of LED lamps and lanterns. If you, how will choose?
