Double oscillator battery powered flashing superluminescent light emitting diode safety warning light

A portable flashing safety warning light, comprising:

• light source means comprising at least one superluminescent light emitting diode;
• high frequency oscillator means operably connected with the light source means for generating an oscillatory drive signal and providing said oscillatory drive signal to the light source means at a high frequency such as to cause the light source to be flashed thereby in accordance with said oscillatory drive signal at a visually imperceptible flash rate such that said light source when so driven with said oscillatory drive signal appears to be constantly illuminated;
• low frequency oscillator means operably connected with said high frequency oscillator means for providing a gating signal having periodic on and off states at a low visually perceptible frequency to the high frequency oscillator for causing the high frequency oscillator to generate and provide said oscillatory drive signal to said light source means only during periods of said gating signal when said gating signal has an on state and for causing generation of said oscillatory drive signal by said high frequency oscillator to be inhibited during periods of said gating signal when said gating signal has an off state, for thereby causing said light source to be illuminated and extinguished at a visually perceptible flash rate;
• power driving means operably connected between the high frequency oscillator means and the light source means for switching a drive current supplied to said light source means on and off in accordance with said oscillatory drive signal;
• switching means for selectively switching the high frequency oscillator means continuously on regardless of the state of the gating signal, for thereby continuously providing the oscillatory drive signal to the light source means;
• and
• housing means for enclosing the light source means, high frequency oscillator means, low frequency oscillator means, power driver means and a battery power supply source therefor, said switching means being mounted on said housing means.
