LED lights can save energy up to 48%
Important info for those of you who do not know that the use of lamp type LED (Light Emitting Diode) to save on electricity bills and also reduce indoor heat compared to using ordinary lamps (fluorescent, bulb or other).
LED lights
A company in North Carolina, United has made the building they use LED lights instead of ordinary light.
As a result, they can save the energy used to 48% (mean savings on electricity bills) plus a little heat generated by LEDs, making them do not need to set the air conditioner (AC) in their maximum position, which means there is a savings again.
So, if you want to save on electricity bills, replace your lamp type LED dengnan, maybe a little pricey but for a long time, you can gain a lot more of course. Read also the article on LED lights: save on electricity bills LED lights.
The current/voltage characteristic of an LED is similar to other diodes, in that the current is dependent exponentially on the voltage (see Shockley diode equation). This means that a small change in voltage can cause a large change in current. If the maximum voltage rating is exceeded by a small amount, the current rating may be exceeded by a large amount, potentially damaging or destroying the LED. The typical solution is to use constant current power supplies, or driving the LED at a voltage much below the maximum rating. Since most common power sources (batteries, mains) are not constant current sources, most LED fixtures must include a power converter. However, the I/V curve of nitride-based LEDs is quite steep above the knee and gives an If of a few milliamperes at a Vf of 3 V, making it possible to power a nitride-based LED lights from a 3 V battery such as a coin cell without the need for a current limiting resistor.
