Problems solved by technology

Therefore, if a large number of light-emitting diodes need to be used, additional large-scale voltage conversion components (such as large-scale transformers with high turn ratios) need to be used; however, large-scale voltage conversion components will have defects such as large volume and high price.

Embodiment Construction

[0059] In order to fully understand the purpose, features and effects of the present invention, the present invention will be described in detail by means of the following specific embodiments and in conjunction with the accompanying drawings, as follows:

[0060] figure 1 It is a schematic functional block diagram of an LED power supply circuit according to an embodiment of the present invention. see figure 1 . existfigure 1 Among them, the LED power supply circuit 1 converts a first electric energy E1 into a second electric energy E2. The second electric energy E2 is used to drive a light emitting diode 2 , and the light emitting diode 2 is converted into a light energy LE by means of the second electric energy E2 . Wherein, the first electric energy E1 is, for example, an alternating current, and the second electric energy E2 is, for example, a direct current. The voltage range of alternating current is between 50 volts and 380 volts. This embodiment does not limit the...

Abstract

The present invention provides an LED power supply circuit and a bulb with the same. The LED power supply circuit is used for converting alternating current into direct current, so as to drive at least one LED to output optical energy. The LED power supply circuit comprises an input unit, a current protection unit, a power supply adjusting unit, a rectifier module and an output unit; wherein the input unit is used for receiving the alternating current; the current protection unit is coupled to the input unit and is used for suppressing a current pulse and correspondingly outputting the alternating current; the power supply adjusting unit is coupled to the current protection unit and used for controlling and adjusting the current and the power of the alternating current; the rectifier module is coupled to the power supply adjusting unit and used for converting the alternating current into the direct current; and the output unit is coupled to the rectifier module and at least one LED, and used for outputting the direct current to the at least one LED. Through adoption of the LED power supply circuit and the bulb in the present invention, the service lives of the LED power supply circuit and the bulb can be prolonged.

Description

technical field [0001] The invention relates to a light emitting diode power supply circuit and a light bulb with the light emitting diode power supply circuit, in particular to a light emitting diode power supply circuit in the technical field of lighting control and a light bulb with the light emitting diode power supply circuit. Background technique [0002] At present, green energy lighting widely uses light-emitting diodes as light sources, and light-emitting diodes are driven by direct current to generate electro-optical conversion. [0003] Generally speaking, the LED obtains a DC voltage by means of a stabilized integrated circuit (IC). The function of the integrated voltage regulator circuit is to convert the alternating current into direct current to generate the voltage required to drive the light-emitting diodes. As an example, a voltage-stabilizing integrated circuit converts alternating current to approximately 5 volts direct current. [0004] However, during...
