Abstract

The present invention provides an LED lamp structure, including a circuit board, a circular coil, and a lamp housing. The circuit board has one or more LED light bulb mounted thereon, and the circular coil includes an iron core, a primary winding and a secondary winding, wherein the primary winding of the circular coil is connected with the lamp housing for conducting an AC power, and then, the secondary winding, which is connected with the circuit board, is induced to produce a DC power for transmitting to the circuit board, thereby lighting up the LED light bulb on the circuit board.

Claims

1. An LED lamp structure, which is connected with an AC power source for converting thereof into a DC power so as to light up at least an LED light bulb, the LED lamp structure comprising:

a light reflection board, having through holes pre-mounted thereon for embedding at least an LED light bulb therein in a geometric pattern;

a circuit board, embedded under the light reflection board and having plural power connecting points for acquiring the DC power and for electrically connecting with the LED light bulb;

a circular coil, comprising an iron core which is wound by at least a primary winding and a secondary winding, wherein the secondary winding is connected with plural power connecting points of the circuit board so as to electrically connect the circuit board with the circular coil; and

a lamp housing, having a hollow accommodating space for accommodating the circular coil, wherein the circuit board and the LED light bulb are mounted at one end of the lamp housing, the lamp housing has two power connecting points mounted thereon for conducting the AC power, the primary winding of the circular coil is connected with the two power connecting points for acquiring the AC power via the lamp housing, and the secondary winding of the circular coil outputs non-harmonic power to the circuit board for lighting up the LED light bulb.

2. The LED lamp structure as claimed in claim 1, wherein the lamp housing further comprises a lampshade mounted at the end locating the circuit board.

3. The LED lamp structure as claimed in claim 1, wherein the lamp housing further comprises a screwing portion with threads at one end thereof for screwing with a lamp holder.

4. The LED lamp structure as claimed in claim 1, wherein plural power connecting points of the lamp housing are mounted at the screwing portion.

5. The LED lamp structure as claimed in claim 1, wherein the circular coil further comprises an inner tube located between the iron core and the primary winding, and a pair of covers symmetrically covered together for isolating the primary winding and the secondary winding.
