The circuit uses a switch to switch the conduction of the LED strings to change the color temperature of the light emission of the lamp, so that the control module will adjust the light emitting brightness of the lamp for better dimming range and work performance of the whole circuit if a driving voltage is in a mono sinusoidal voltage section greater than or equal to 129 volts and smaller than or equal to 135 volts.

Abstract: A solid-filled encapsulated LED bulb with a base, at least one LED light source and at least one power supply element includes a transparent solid-filled heat-dissipating light guide member attached and covered onto the LED light source and the power supply element. A side of the heat-dissipating light guide member is packaged with the base to form the LED bulb. The heat of the LED light source is conducted and dissipated to the outside through the heat-dissipating light guide member. A light of the LED light source is outputted with an intensity IA through the heat-dissipating light guide member. The intensity IA of the light and the intensity IB of the LED light source satisfy the condition of (IA/IB)>70%. The use of a conventional dissipating structure is skipped to reduce the production cost and expedite the assembling and packaging processes while maintaining excellent heat dissipation and light output effects.
