Description

technical field [0001] The invention relates to a power supply device, in particular to a constant-voltage dimming power supply device compatible with multiple dimming methods. Background technique [0002] LED is a display device with excellent performance, which has the advantages of long life, energy saving, high brightness, various luminous colors, fast response speed and low driving voltage. While saving energy, it can also adjust the LED luminous intensity, change the luminous color, and realize various display effects. Now it is widely used in urban lighting, architectural landscape lighting, stage lighting design and other fields. [0003] In the dimming application of LEDs, dimmable power supplies are classified from the perspective of dimmer types: AC phase-cut dimming power supplies, 0-10V (1-10V) dimming power supplies and other dimming power supplies. Because the traditional LED dimmable power supply cannot solve the above dimming methods at the same time, the...
