Abstract

This invention describes a lighting device with low energy consumption, which is made up of light emitting diodes known by the English acronym of LEDs, that use the technique known as “scanning”; with the purpose of reducing the consumption of energy required for lighting. Said scanning is performed by an efficient circuit that determines the sequence and time required for the activation of each LED or group of LEDs. The invention does not limit itself to only using LEDs, other types of elements for control may be used that may be sequenced without altering its operation or useful life. In this case, the speed that may support the LEDs is taken advantage of and that is higher than can be seen by the human eye, where each LED or group of LEDs are turned on and off at a frequency that is imperceptible by the human eye.Solutions are also presented to reduce the voltage by electronic means and rectification of the current using the LEDs themselves that intervene in the lighting.
