Abstract

A low voltage driven high brightness LED that applies the lower driving voltage than the known LED and has brighter than the known LED'"'"'s; the present invention is a packaging with a circuit board on bottom, a voltage regulation IC and a flashing control IC are on the bottom of the circuit board, at least one LED chips are on the top center of the circuit board, these LED chips can be driven with lower voltage and generate brighter light, a single LED packaging generates multiple color flashing function and achieves smaller physical size, stronger structure and convenient to apply effect.

Claims

1. A low voltage driven high brightness LED comprising:

a packaging in lamp shape with an LED chip, two or more connecting pins stretch out from said packaging;

a circuit board inside said packaging;

one or more LED chips are on the top center of said circuit board;

a voltage regulation IC applies the voltage regulation circuitry and the vibration circuitry to raise power voltage, and applies capacitor for voltage filtering to adjust the input power for the normal LED chip driving voltage; and

a flashing control IC is on the back of said circuit board.

2. The low voltage driven high brightness LED recited in claim 1, wherein said flashing control IC drives one or more said LED chips flash in turn or at the same time.

3. The low voltage driven high brightness LED recited in claim 1, wherein said LED chip is a die before packaging, said LED chip is fixed on said circuit board directly then is bonded with wires.

4. The low voltage driven high brightness LED recited in claim 1, wherein said LED chip is a packaged LED unit and is fixed on said circuit board with SMD technology.
