Light emitting bio-mimicry method

摘要

A system and method are provided for mimicking a bioluminescent signal from an animal or an insect, such as a firefly. A first version includes a controller, an electrical energy battery, a solar energy collector and a light emitting device. The solar energy collector receives sunlight and converts the sunlight to electrical energy that is stored in the battery. The electrical energy battery provides electrical energy to the light emitting device under management by the controller, and may comprise two or more battery cells or circuits. A time sequence for energizing the light emitting device may be applied to cause the light emitting device to mimic a bioluminescent lighting pattern generally exhibited by a selected species of insect or animal. A light emitting diode may be used with a voltage source and a voltmeter to detect the approximate intensity of light of an ambient environment surrounding the device.

1. A method for evaluating an energy intensity of ambient light comprising:
a. providing a controller coupled with a memory, an electrical power supply and a light emitting diode (“diode”), the memory storing a stored voltage value (VR2), and the controller is adapted to receive a detection of ambient light intensity from the diode, wherein the controller is programmed to couple the electrical power supply to the diode when the derived intensity of ambient light is less than a reselected ambient light intensity level; b. exposing the diode to an ambient light environment, the diode having a cathode and an anode; c. imposing a test voltage (Vt) at a time zero T0 between the cathode and the anode of the diode, wherein the test voltage (Vt) is less than a peak inverse voltage of the diode; d. the controller measuring a dynamic voltage (Vt) instantiated between the cathode and an anode over time and after the time zero T0; e. the controller determining a delay time (Td) extending between the time zero (T0) and a time mark (Tm), the time mark (Tm) determined when the dynamic voltage (Vd) is detected to be less than the stored voltage value (VR2); and f. the controller deriving the intensity of the ambient light from decay time (Td).
