Abstract:
A two-level LED security light includes a light-emitting unit comprising at least an LED load which may be turned on or turned off by a light sensing control unit. A motion sensing unit upon an intrusion detection activates the LED load to generate a high level illumination for a time length adjustable by a time setting unit. The LED load is operated in compliance with a power supply unit wherein a voltage V across each LED is confined in a range V th <V<V max , with V th  a threshold voltage and V max  a maximum voltage. The light-emitting unit may be configured with two LED lighting loads emitting lights with different color temperatures, wherein a power allocation circuitry may be installed to respectively distribute different electric powers to the two LED loads to manage a color temperature tuning scheme thru a light diffuser.

Claim (Index 32):
A method of dimming an LED load powered by an AC power, comprising:\n using a phase controller electrically coupled between an AC power and an LED load to control a transmission of an average electric power delivered to the LED load; using a zero crossing point detection circuit to identify a zero crossing point information in each AC half cycle; using a controller incorporating with the zero-crossing point detection circuit to output a time delay pulse with a delay time t D  lagging behind the zero-crossing point in each half cycle of the AC power to control a conduction rate of the phase controller for delivering an average electric power to drive the LED load for generating an illumination, wherein in order to ensure a successful conduction of the phase controller the delay time t D  is confined to operate in a time phase domain between t 0  and 1/2 f\u2212t 0 , wherein f is the frequency of the AC power source, and t 0  is a corresponding time phase of a cut-in voltage of the LED security light due to the LED load at which the LED load starts to emit light in each positive and negative half cycle of the AC power; and using an external control device usable by an user to output an external control signal to the controller to accordingly output the time delay pulse to control the conduction rate of the phase controller; wherein the phase controller contains a bidirectional semiconductor switching device, wherein the LED load is a DC LED module comprising a plurality of light emitting diodes, wherein the DC LED module is electrically connected to a full wave rectifier, wherein the full wave rectifier converts the AC power delivered by the phase controller into a DC power to drive the LED load for generating an illumination.
