A motion activated and light sensitive multi-purpose safety light, having a housing for supporting: a motion sensor; a light emitting diode which serves as both a light source and a light detector; an electronic circuit which further comprises; a motion sensor amplifier to condition the motion signal received from the motion sensor, a driver for illuminating the light emitting diode in a flashing manner, a timer enabling the operation of the driver and a photo-amplifier providing amplification of the input signal received from the light emitting diode. A user-selected control components for providing parameters relating to the conditioning and the flash rate. A printed circuit board providing an area to mount the electrical components and electric circuit and a system power source.
A motion activated and light sensitive multi-purpose safety light, comprising:
A motion activated and light sensitive multi-purpose safety light, comprising:
A motion activated and light sensitive multi-purpose safety light, comprising:
A signal emitting device, comprising a signal emitting component and a motion sensor for activating said signal emitting component, said motion sensor comprising, a piezoelectric crystal element, said piezoelectric crystal element being attached to a mass at a first point and to a support structure at a second point, said support structure being attached to a body whose motion is to be detected, said first point being positioned relative to said second point to result in the application of a positive or negative compression to said piezoelectric crystal element when said body whose motion is to be detected moves, causing said piezoelectric crystal element to respond to such compression with an electrically detectable change in characteristics.
