| titleOfInvention | Led unit and unitary regulating led lamp of constant-current type |
| abstract | Disclosed are an LED unit and a unitary regulating LED control circuit of constant-current type. The unitary regulating LED control circuit of constant-current type comprises a rectification bridge connected to a power source, at least one LED control unit series branch as mentioned above connected to the rectification bridge, and at least one current-limiting resistor. The solution plays the role of voltage stabilization for the whole unit using the characteristic of forward voltage drop of a regulating tube and a diode, the control thereof is cheaper and more practical, and higher in efficiency. In addition, when the voltage of the power source is lower than the normal voltage of the power supply, because the whole circuit operates in an operating state with a value lower than a regulating value and the lowered voltage is distributed evenly by all unitary regulating circuits, the brightness of all LEDs is decreased uniformly, thereby achieving a continuous dimming function within a certain voltage range. Practice has proved that the whole circuit can reliably operate within the voltage range of AC/DC 120V to 270V. |
