Abstract

A LED lamp tube connectable to a conventional lamp holder is disclosed to include a circuit board, multiple arrays of LEDs (light emitting diodes) installed in the circuit board, an outer tubular shell that accommodates the circuit board and the LEDs, and two electric connectors provided at the two ends of the circuit board and extending out of the tubular shell for connecting the circuit board to respective connecting holes at a conventional lamp holder to obtain the necessary working voltage.

Claims

1. A LED lamp tube comprising a circuit board made subject to the size of a conventional lamp holder, multiple arrays of light emitting diodes installed in said circuit board, and two electric connectors for connecting said circuit board to respective connecting holes at said conventional lamp holder for enabling said light emitting diodes and said circuit board to obtain the necessary working voltage from said connected lamp holder.

2. The LED lamp tube as claimed in claim 1, wherein said two electric connectors of said LED lamp tube are respectively electrically connected to two opposite ends of said circuit board.

3. The LED lamp tube as claimed in claim 1, wherein said electric connectors are tube pin type electric connectors.

4. The LED lamp tube as claimed in claim 1, wherein said electric connectors of said LED lamp tube each are comprised of at least one plug member.

5. The LED lamp tube as claimed in claim 1, further comprising a tubular shell that accommodates said circuit board and said light emitting diodes.

6. The LED lamp tube as claimed in claim 5, wherein said tubular shell is transparent, translucent, partially transparent or any of a variety of other materials in any of a variety of colors.

7. The LED lamp tube as claimed in claim 5, wherein said tubular shell comprises a flat mounting base that supports said circuit board and said light emitting diodes on said circuit board, and a light permeable shade covered on said flat mounting base over said circuit board and said light emitting diodes, and said flat mounting base is formed integral with said light permeable shade.
