Small, Wide Input Voltage Range LM2842 Keeps LEDs Cool

The world seems to be poised to make the leap to LED lighting. Incandescent has been deemed too inefficient, which it is, and fluorescent lighting often does not achieve the lifetime it claims. Fluorescent also has another set of baggage, dangerous chemicals. So the logical choice that most people believe can take the crown is HB (high brightness) LEDs. HBLEDs are becoming more attractive as the manufacturers of such devices are making great strides in increasing the lumens per watt that they can produce which improves the efficiency. It will not be long before LEDs produce significantly more lumens per watt than current fluorescent lamps.
