Description

LED intelligent power

Technical field

The utility model relates to a kind of LED intelligent power.

Background technology

Along with people's quality of the life improves constantly, fixed light source cannot meet the requirement of people to environmental protection and living environment.Use existing technology platform, by plug-in device or mobile device, LED driver is controlled, change brightness and the colour temperature of LED, build more warm comfortable environment.

The TRIAC dimming power source majority used in the market adopts pure hardware circuit to form, circuit structure is complicated, the compatibility of dimmer and the linear of light modulation are not all very desirable, still it is bad to there is dimmer compatibility in the scheme being supplied to client, the problem such as the collocation of dimmer and light adjusting circuit and load is bad, the problems such as during main manifestations light modulation, subregion has flicker, and noise is obvious.Meanwhile, it is corresponding with it that the dimmer for different manufacturers model often needs different driving powers, and this not only needs when lighting system construction layout the stock buying Multiple Type, very bothers, and cannot form general implementation criteria.

Utility model content

For problem mentioned in background technology, the utility model proposes a kind of LED intelligent power, solve the dimming behavior of existing LED dimmer and the problem of compatible performance, conveniently upgrading on the basis of existing lamp wiring, its technical scheme adopted is as follows:

A kind of LED intelligent power, comprises power unit and control section,

Described power unit comprises the prime module primarily of ac-dc converter circuit composition, and primarily of the post-module that constant current chip and peripheral circuit thereof form, described post-module has the one group of output being connected to controllable silicon dimmer;

Described control section comprises single-chip microcomputer and peripheral circuit thereof, and this single-chip microcomputer is provided with the control output end to described constant current chip, and corresponding peripheral control unit, operating key some inputs of panel, this some input is connected to external binding post.

In the middle of one or more embodiment of the present utility model, described single-chip microcomputer is also provided with the detection input of the output to described post-module, for obtaining the signal of telecommunication exporting controllable silicon dimmer to.

In the middle of one or more embodiment of the present utility model, described single-chip microcomputer is also connected with a toggle switch, for being arranged the output current of described post-module by described constant current chip.

In the middle of one or more embodiment of the present utility model, the Enable Pin being connected to and connecting described external binding post also put by described single-chip microcomputer, for receiving the enable signal controlling mains switch.

In the middle of one or more embodiment of the present utility model, described prime module also comprises pfc circuit.

The utility model is compared with existing product, and its superiority is:

1) by coordinating with existing controllable silicon dimmer the brightness adjusting LED light source, more than 95% can be reached to controllable silicon dimmer compatibility;

2) single-chip microcomputer detects the voltage exporting controllable silicon dimmer to, utilizes its disposal ability to control to improve dimming effect;

3) utilize single-chip microcomputer to receive process DALI1-10V, button dim signal, make power supply can compatible multiple light-modulating mode, be applicable to more light adjusting systems and occasion, such that the control of LED illumination is more intelligent, networking and hommization;

4) power unit adopts single-stage PFC scheme, effectively improves power factor and reaches more than 0.9, reduces supply harmonic;

5) support that multiple current exports, use toggle switch to get final product multiple output current, to adapt to the constant current light fixture of different output current specification.
