Abstract: An energy saving light bulb is revealed. It comprises a lampstand having a conductive connector, a pyramid assembly having a plurality of assembly surfaces, a plurality of LEDs and a plurality of rectifier diodes disposed on the plurality of assembly surfaces, a choke inductor having a first and second terminals disposed on the pyramid assembly, and a lampshade for assembling on the lampstand to shelter the pyramid assembly, the plurality of LEDs, the plurality of rectifier diodes and the choke inductor, wherein the first and second terminals connect to the plurality of LEDs, the plurality of rectifier diodes and the conductive connector of the lampstand.

Abstract: A fluorescent lamp with a new LED tube is revealed herein to have at least one terminal socket at both sides of a lamp holder for terminals disposed at both sides of the LED tube to be plugged therein, wherein each terminal socket in the lamp holder is coupled with each of plural second substrates assembled with a filter inductor, and a rectifier diode disposed on a first substrate having light emitting diodes in the LED tube for output of a DC power with high or low voltage constant current suitably used in the light emitting diodes, so that the power efficiency for the light emitting diodes of the LED tube can be improved, the heating temperature of the light emitting diodes can be lowered and the life span for the LED tube can get longer.
