Embodiment Construction

[0015] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0016] Reference figure 1 with figure 2 , An embodiment of the stepless dimming LED lamp of the present invention is proposed. The stepless dimming LED lamp includes an AC / DC constant current driving power supply 10, an LED light source 1, and is used for stepless dimming of the LED light source 1. The SCR dimming module 30, a main control chip for controlling the SCR dimming module 30, and a main control switch 40 connected to the main control chip.

[0017] The main control chip is a PIC16F1933 single-chip microcomputer 20 with a flash program, including a flash program memory 22 that can store any brightness lighting code and a PWM output module 21; the thyristor dimming module 30 includes a zero-crossing detection circuit 31 and a phase shift circuit 32 And the thyristor 33. The zero-crossing detection circuit...

Abstract

The invention discloses a stepless dimming type LED lamp which comprises a silicon controlled dimming module, a main control chip and a main control switch. The main control chip is a single chip microcomputer with a flash program and comprises a flash program storage and a PWM output module, the silicon controlled dimming module comprises a zero cross detection circuit, a phase shift circuit and silicon controlled, the zero cross detection circuit is connected with the main control chip, the silicon controlled is connected with an LED light source, and the PWM output module is connected with the silicon controlled through a PWM output port. The main control switch is turned on, the single chip microcomputer is in the initial working state, and the LED light source slowly lights from 0%-100%. During lighting of the LED light source, the LED light source can be rated at the current illumination by turning off the main control switch and turning on the main control switch again in 1.5 second, and continuous stepless dimming without flashing can be easily achieved. The stepless dimming type LED lamp has the remote control dimming function, the delay light turning-off function and the wall switch turning-on and turning-off function. Practicality is reinforced for a user.

Description

Technical field [0001] The present invention relates to the field of LED lighting, in particular to a stepless dimming LED lamp that can be remotely controlled. Background technique [0002] At present, LED light sources are gradually replacing incandescent lamps and fluorescent light sources with long life, pollution-free, and high luminous efficiency. Therefore, LED lamps using LEDs as light sources have appeared. Users are accustomed to using lights with different brightness at different times, so according to the different requirements of customers, the lights need to have brightness adjustment function. The existing dimmable LED lamp does not have a brightness memory function, and the brightness is fixed every time when the lamp is turned on, and the brightness needs to be readjusted, which brings inconvenience to the user. [0003] Therefore, how to design a stepless dimming LED lamp with brightness memory function is the technical problem to be solved by the present inventi...
