Problems solved by technology

[0002] Traditional lighting technology has disadvantages such as low luminous efficiency, high power consumption, and short service life. LED lighting has the advantages of long life, energy saving, safety, and environmental protection, and is rapidly replacing traditional lighting.
The traditional dimming realizes the switching of the brightness of the light source by turning on and off the power switch. Every time the switch is turned on and off, the light source can only choose one state, which not only complicates the dimming process, but also and turn-off times, affecting the life of the light source

Embodiment approach

[0074] According to a specific implementation manner, the converter includes a decoder and a multiplexer, wherein,

[0075] The decoder is configured to decode the turn-on logic level signal and / or the turn-off logic level signal;

[0076] The multiplexer is used to select a corresponding output reference voltage signal according to the control signal obtained after decoding.

[0077] preferred, such as image 3 As shown, the first embodiment of the converter 202 includes a decoder 310 and a multiplexer 311; the input signal of the decoder 310 is the output signals N34 and N35 of the detector 201; the decoder 310 decodes N34 and N35, and outputs a first control signal N40, a second control signal N41, a third control signal N42, and a fourth control signal N43;

[0078] The input signals of the multiplexer 311 are the first reference voltage signal N45, the second reference voltage signal N46, the third reference voltage signal N47 and the fourth reference voltage signal N48...

Abstract

The invention provides an adjusting device of an LED (Light-Emitting Diode) light source. The adjusting device comprises a detector, a converter and a driver, wherein the driver is used for detecting the Nth on time of a power switch of the LED light source and / or the Nth off time of the power switch of the LED light source, comparing the Nth on time with a preset on time to generate an on logic level signal, and comparing the Nth off time with a preset off time to generate an off logic level signal; the converter is used for converting the on logic level signal and / or the off logic level signal into a reverence voltage signal; the driver is used for adjusting the brightness of the LED light source according to the reference voltage signal after the power switch of the LED light source is on for the (N+1)th time; and N is a positive integer. According to the invention, on the basis of not increasing peripheral circuits and extra cost, the LED light source can be adjusted conveniently, simply and rapidly.

Description

technical field [0001] The invention relates to an adjusting device, in particular to an adjusting device for an LED light source. Background technique [0002] Traditional lighting technology has disadvantages such as low luminous efficiency, high power consumption, and short service life. LED lighting has the advantages of long life, energy saving, safety, and environmental protection, and is rapidly replacing traditional lighting. The traditional dimming realizes the switching of the brightness of the light source by turning on and off the power switch. Every time the switch is turned on and off, the light source can only choose one state, which not only complicates the dimming process, but also And the number of shutdowns will affect the life of the light source. Contents of the invention [0003] The main purpose of the present invention is to provide an LED light source adjustment device, which can realize convenient, simple and rapid adjustment of the LED light sou...
