Abstract

The invention discloses an adaptive adjusting constant-power control method for an LED lamp. The method comprises the steps of wiring, total voltage measurement, comparison, current measurement, acquisition, primary adjustment, detection, calculation, secondary adjustment and feedback. The method is scientific and reasonable, and is safe and convenient to use; the number of working lamp beads of the LED lamp can be adjusted by adjusting acquired working power of the LED lamp, so that the LED lamp keeps constant-power work; a duty ratio of the LED lamp is adjusted and updated, so that the dutyratio can be adjusted to further adjust a current and a voltage in a circuit, and the adjustment is more accurate; the adjusted working power of the LED lamp is transmitted to a microprocessor throughdetection and feedback, so that the microprocessor can determine a current actual working state of a controlled object by continuously collecting control the process information; and performance criteria are optimized to adjust the structure or parameters of a controller in real time, so that a system can automatically work in an optimal or sub-optimal operation state all the time, the operationis simple, and the LED lamp works more intelligently.

Description

technical field

[0001] The invention relates to the technical field of LED lamps, in particular to an LED lamp self-adaptive adjustment constant power control method. Background technique

[0002] As a new and most potential light source, LED lighting has attracted more and more attention due to its advantages of energy saving and environmental protection; coupled with the policy encouragement of the national and local governments, my country's LED lighting industry has entered a stage of accelerated development. The market is growing rapidly. The LED lamp is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connected to the chip and the circuit board with silver or gold wires, and sealed with epoxy resin around it for protection. The role of the inner core wire.

[0003] During the working process of ordinary LED lights, because LEDs have the volt-ampere characteristics of diodes, that is, after applying...
