New description: [New technical field] This creation is about a light-emitting diode device, especially a dimmable light-emitting diode device. [Prior Art] Since the invention of incandescent bulbs such as tungsten filament bulbs or dentate bulbs, although the demand and desire of human light have been solved, it has also opened up humanity's further requirements for light's in order to meet the different needs of users, nowadays It has been possible to manufacture incandescent bulbs with various brightnesses. In addition, in order to achieve the purpose of adjusting the brightness of incandescent bulbs, the technology of driving incandescent bulbs with dimming circuits has been developed and applied. 'Controlling incandescent bulbs by dimming circuits Luminous brightness. A conventional dimming circuit for an incandescent light bulb includes a switching element and a trigger circuit, wherein the switching element can be a solid state semiconductor element, such as a triac (TRAIC), which controls the switching phase of the switching element by a trigger circuit or Time to control the amount of power delivered to the incandescent bulb. However, in recent years, due to breakthroughs in the manufacturing technology of light-emitting diodes which have better luminance and luminous efficiency, they have gradually replaced conventional incandescent bulbs and become new lighting elements, and are widely used, for example, in household lighting devices. However, the traditional dimming circuit is only suitable for purely resistive incandescent bulbs. When applied to a light-emitting diode whose operating characteristics are completely different from those of an incandescent bulb, the LED may not operate properly or even burn out. Occurs, so the traditional dimming circuit does not actually dim the LEDs. Therefore, for example, M435557 develops a lighting driving system capable of being dimmed by improving the above-mentioned conventional technology, and adjusting the brightness of the light-emitting diode is an urgent problem to be solved by the related art.

The AC power source performs the modulation of the conduction phase and the voltage, and the modulation affects the power supply specification of the power conversion circuit, thereby achieving the dimming effect.
