Abstract

An improved arrangement of light-emitting diodes of a LED lamp includes a circuit board and a plurality of light-emitting diodes. The surface of the circuit board is provided with a layer of conductive circuit, so that the light-emitting diodes can be arranged on the circuit board and electrically connected to the conductive circuit. On the surface of the circuit board provided with the conductive circuit, an imaginary circle is defined. Further, the light-emitting diodes are distributed on the circuit board along the imaginary circle to form a circular arrangement.

Claims

1. An arrangement of light-emitting diodes of a LED lamp, comprising:

a circuit board provided on one surface thereof with a layer of conductive circuit; and

a plurality of light-emitting diodes respectively provided on the circuit board to be electrically connected to the conductive circuit,

wherein on the surface of the circuit board provided with the conductive circuit, an imaginary circle is defined, and the light-emitting diodes are distributed on the circuit board along the imaginary circle to form a circular arrangement.

2. The arrangement of light-emitting diodes of a LED lamp according to claim 1, wherein positive and negative contacts of the conductive circuit are located at an outer periphery of the light-emitting diodes.

3. The arrangement of light-emitting diodes of a LED lamp according to claim 1, wherein a plurality of imaginary circles are further defined, each imaginary circle is arranged in a concentric way, and the light-emitting diodes are distributed on each imaginary circle.

4. The arrangement of light-emitting diodes of a LED lamp according to claim 3, wherein each light-emitting diode on inner and outer imaginary circles is staggered.

5. The arrangement of light-emitting diodes of a LED lamp according to claim 1, wherein a position in which each light-emitting diode is arranged on the circuit board is provided with a recess for receiving each light-emitting diode.

6. The arrangement of light-emitting diodes of a LED lamp according to claim 1, wherein each light-emitting diode is formed with a first-ordered lens thereon.
