Abstract

The invention provides a power supply driver automatically matched with various specifications of light source loads, a lamp and a drive method. The power supply driver comprises a digital power supply driver and a feedback circuit; the power supply driver comprises a detection mode and a normal working mode; in the detection mode, a first controller provides a first voltage for the feedback circuit through the driving circuit; the feedback circuit provides a feedback signal for the first controller through the first detection resistor; and after an obtained feedback signal conforms to a predefined format, the power supply driver enters a normal working mode, the first controller provides preset voltage for the feedback circuit through the driving circuit, the feedback circuit does not work, and a light source to be driven emits light. Therefore, the first controller knows the working requirement of the light source through the feedback information of the feedback circuit in the detection mode, and provides the voltage meeting the working requirement of the light source for the light source in the normal working mode, so that one power supply drive can be automatically matched withlight source loads of various different specifications.

Description

technical field [0001] The invention relates to the technical field of lamp driving, in particular to a power supply drive, a lamp and a driving method that automatically matches loads of multi-standard light sources. Background technique [0002] In traditional LED lamps, the driving power supply needs to match the current or power of the lamp one by one. Therefore, lamps with different specifications may need to match multiple driving power supplies with different specifications. Although the traditional digital driver can match a variety of lamps with different specifications, it needs to be manually set or added wiring to match with a variety of lamps with different specifications. Contents of the invention [0003] In view of the above problems, the present invention is proposed in order to provide a power supply drive, a lamp and a driving method for automatic matching of multi-standard light source loads that overcome the above problems or at least partially solve t...
