Description
Technical field:
The invention belongs to and relate to a kind of LED lamp flicker flasher circuit.
Background technology:
Existing LED lamp or light-emitting diode are normal when bright, and be eye-catching inadequately, or material object is too little, is difficult to see clearly and discovery.
Summary of the invention:
The invention provides a kind of LED lamp flicker flasher circuit.The flicker flash of light is convenient to observe, the indication good warning effect.
