1. LED Drivers Waste Energy
Problem: LED drivers are wasting energy
LED light fixtures (with integrated drivers that are receiving AC power) are most likely wasting energy, and this is largely due to their need to convert AC to DC power within drivers. AC to DC converters in LED drivers can be as inefficient as 50% for some recessed downlights, according to our own lab testing at Cence.
Solution: Centralized, efficient AC-DC conversions that distribute to multiple LED fixtures.
2. LED Fixtures Fail Prematurely
Problem: LED fixtures are failing prematurely
Inefficiencies in AC to DC conversions in LED applications ultimately shorten the lifespan of the LEDs themselves. To explain further, inefficiencies waste energy in the form of heat, this heat then causes thermal runaway, and this wears down drivers, causing them to fail prematurely. In fact, according to the U.S. Department of Energy (DOE) accelerated stress testing on LED drivers, 64% of devices failed as a result of AC-to-DC conversion circuitry in less than 4,800 hours of testing, with failure times ranging from 1,250 hours to 4,554 hours.
Solution: Energy efficient DC-DC drivers, which don't generate as much heat in comparison to AC-DC drivers, so they last longer.
3. Safety Concerns
Problem: Safety concerns when installing LED lighting
If installing lighting with an AC line-voltage electrical system, there is a risk of shock or fire.
Solution: Using low-voltage power is safer than using an AC line-voltage system.
With Cence, you can improve the efficiency of commercial and industrial lighting in low and high-voltage applications to reduce operating costs, and lengthen the lifespan of light fixtures.
