Hi, what are you looking for?

CleanTechnica
Light emitting diodes (LEDs) provide long-life lighting technology that powers flashlights, street signs and medical devices. LEDs have bright output with low input power, making them much more energy efficient than their incandescent predecessors. Hybrid capacitors, a combination of an ultracapacitor and a lithium-ion battery, are an ideal choice for LEDs because the low energy and power of LEDs allows hybrid capacitors to be a longer term energy source than alternative energy storage solutions on the market. Other benefits of LEDs to lighting include little to no required maintenance.

Light emitting diodes (LEDs) provide long-life lighting technology that powers flashlights, street signs and medical devices. LEDs have bright output with low input power, making them much more energy efficient than their incandescent predecessors. Hybrid capacitors, a combination of an ultracapacitor and a lithium-ion battery, are an ideal choice for LEDs because the low energy and power of LEDs allows hybrid capacitors to be a longer term energy source than alternative energy storage solutions on the market. Other benefits of LEDs to lighting include little to no required maintenance.

Hybrid capacitors offer an enhanced capability of energy storage in LEDs because they have an energy density up to 115 percent higher than standard electric double-layer capacitors (ELDCs). This allows for faster and more efficient power to applications such as LED lights used in medical devices. Compared with a nickel cadmium or lithium-ion battery, hybrid capacitors provide more than 20 times the cycle life and 60 times faster recharge rates, vastly improving LED lighting products for a variety of industries.

An LED device is brighter, lasts much longer and consumes less than one-third the power and energy of comparable halogen products. Device manufacturers can now design hybrid capacitors permanently into devices because capacitor cycle life generally matches or exceeds device life. Because LEDs use so little energy, hybrid capacitors can provide power for an extended amount of time, saving not only time, but also maintenance costs. For example, medical devices using hybrid capacitors to power the LED lights can charge in 60 seconds and last all day. The hybrid capacitor can last in the device for more than ten years, which often is longer than the device’s lifespan.

As LEDs are more widely adopted, we can expect to see an increase in hybrid capacitors being used to power the lights.
