ENERGY-SAVING LED-BASED LIGHTING DEVICE.

摘要

The invention relates to an energy-saving lighting device formed by light-emitting diodes (LEDs) which use a scanning technique in order to reduce the amount of energy required for lighting. Said scanning technique is performed by an efficient circuit which determines the lighting times and sequence of each LED or group of LEDs. The invention is not restricted to the use of LEDs, but can also be used to control other types of elements which can be sequenced without altering the useful life or operation thereof. This case involves the use of speeds that LEDs can withstand that are beyond that of the human eye, at which each LED or group of LEDs turns on and off at a frequency imperceptible to the human eye. The invention also relates to voltage reduction solutions using electronic means and current rectification using the LEDs that are also used for lighting.
