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 1):
A lifestyle LED security light, comprising:\n a light-emitting unit, including an LED load configured with a plurality of LEDs; a loading and power control unit; a light sensing control unit; a motion sensing unit; and a power supply unit; wherein the loading and power control unit comprises a controller and a switching circuitry, wherein the controller is electrically coupled with the switching circuitry, wherein the switching circuitry is electrically connected between a power source and the LED load of the light-emitting unit, wherein the LED load is switched on or switched off by the light sensing control unit and controlled by the loading and power control unit, wherein the switching circuitry comprises at least a semiconductor switching device for controlling transmission of different electric powers delivered to the LED load, wherein the controller outputs control signals to control the switching circuitry for delivering different electric powers from the power source to drive the light-emitting unit for generating different illuminations characterized by different light intensities according to signals received from the light sensing control unit and the motion sensing unit; wherein the power source configured in the power supply unit outputs a DC power for operating the LED lighting device; wherein the semiconductor switching device is an unidirectional semiconductor switching device, wherein the control signals are pulse width modulation signals; wherein a time setting unit is further installed for adjusting and setting a time duration for each of the different illumination modes, wherein when an ambient light detected by the light sensing control unit is lower than a first predetermined value, the loading and power control unit operates to switch on the LED load to perform a first illumination mode to generate a first level illumination for a first predetermined time duration preset by the time setting unit, wherein when a motion intrusion is detected by the motion sensing unit, the loading and power control unit manages to increase the electric power transmitted to the LED load to perform a second illumination mode to generate a second level illumination for a second predetermined time duration preset by the time setting unit, wherein the light intensity of the second level illumination is higher than the light intensity of the first level illumination, wherein when the ambient light detected by the light sensing control unit is higher than a second predetermined value, the loading and power control unit operates to switch off the LED load; wherein the first level illumination is a low level illumination and the second level illumination is a high level illumination, wherein during the performance of the first illumination mode, the low level illumination creates three advantages for performing a lifestyle lighting solution, wherein a first advantage is a creation of an aesthetic night scene when people are outside of a detection area of the motion sensor, wherein a second advantage is the creation of a navigation capacity similar to a light house for guiding people to safely walk to a destination in an outdoor living area, wherein a third advantage is a prevention of a hardship of light being unexpectedly and completely shutoff while a person is still in the detection space due to expiration of a timer and a simple motion by the person can immediately bring the LED security light back to the high level illumination.
