Description

A kind of intelligent lamp controller

1, technical field:

The utility model relates to a kind of intelligent lamp controller, relates in particular to the intelligent lamp controller that has multistage dimming function.

2, background technology:

At present, very big variation has taken place in the tungsten lamp source based on incandescent lamp, come out one after another in the lamp source of arising at the historic moment, wherein the high-pressure halogen lamp of G9, G10 series begins to be extensive use of, this class lamp source is advantage such as low and warm light and long the Sheng with price, but its shortcoming is: useful life is shorter, elder 1000 hours; Weak point person 400 hours.Particularly general lighting device and auxiliary switch thereof all are the complete bright states that just promptly enters when electric power starting at present, if filament is closed and is in temperature when low in outage, enter that complete bright state enters a higher temperature and the electric current that passes through when big suddenly, filament is subjected to bigger impact and burns easily, has caused the waste of direct economic loss and maintenance resources.In addition, the lamp decoration product of using this type of lamp source mainly is: pendent lamp, ceiling light, desk lamp etc., the used bulb quantity of this type of light fixture does not wait to hundreds of is individual by one, pendent lamp, the installation site of ceiling light is than higher, it is difficult that bulb burns the back replacing, realize that the light control of this type of light fixture also must install special-purpose dimmer, present dimmer is that separate independent made and installed with the mains switch of light fixture, dimmer just works after only opening the mains switch of light fixture, common dimmer can only be done continous way light modulation and the light modulation of stepping formula, general dimmer is by manual mode of operation light fixture to be realized by dark to bright variation, but send a telegram in reply again in case grid cut-off occurs, when perhaps using the mains switch of light fixture is turn-offed and the gear of dimmer is not transferred to extreme lower position, when reopening the mains switch of light fixture again, light fixture is understood moment equally and is entered complete bright state, thereby can influence the life-span of bulb.That present dimmer has is rotary, drag singly-key type directly is operating as the master on dimmer, its volume is bigger, must install side by side with the mains switch of light fixture during installation, take the effect that certain metope space and influence are decorated, for installing but do not have the light fixture of dimmer to rethink dimmer is installed to bother very much, must rewiring and dimmer is installed on the wall, install very inconvenient.

Use aspect: under the environment of dark, open light fixture, light fixture enters complete bright state immediately, light is stronger, and the high light line that comes can bring dazzling bad reaction to human eye suddenly, and in fact regular this class situation that occurs can cause to a certain degree infringement to human eye.

3, summary of the invention:

The purpose of this utility model provides a kind of intelligent lamp controller, it by at the mains switch of light fixture when opening, light fixture is in by secretly slowly rising to certain brightness, utilize the fast quick-break of the mains switch/logical signal that measures light fixture simultaneously, make light fixture be in certain brightness and slowly rise to stronger brightness, realize the gear shift function, bulb is operated under the good state, working life prolongs greatly, save the expense of safeguarding, gear-change operation is simple simultaneously, and is convenient with the mains switch connection of light fixture, need not take the metope space.

The utility model is achieved by the following technical solution: it is by step-down rectifying circuit, the synchronizing signal sampling, reset samples, luminosity logic control and electronic switch are formed, the input of step-down rectifying circuit is connected with the AC power input, the step-down rectifying circuit output is luminosity logic control power supply, the input of synchronizing signal sampling links to each other with the AC power input, the input of reset samples is connected with the step-down rectifying circuit output, the synchronizing signal sampling is connected with the input of luminosity logic control with the output of reset samples, the output of luminosity logic control is connected with the control end of electronic switch, and electronic switch is connected with the AC power input with bulb load series connection back.

Also be provided with filter circuit between above-mentioned described step-down rectifying circuit and the AC power input.

The utility model compared with prior art has following advantage: 1) open by the mains switch of light fixture, light fixture is in by secretly slowly rising to certain brightness, utilize the fast quick-break of the mains switch/logical signal that measures light fixture simultaneously, make light fixture slowly rise to the maximum brightness of corresponding gear by darker brightness, suppressed of the impact of the big electric current of transient state effectively to bulb, realize that light modulation gear shift function always works under the steady good state bulb, working life prolongs greatly, failure rate greatly reduces, and saves the expense of safeguarding; Two lines were connected with AC power input by the mains switch of light fixture when 2) intelligent lamp controller was installed, two wires are connected with bulb load in addition, wiring is simple, the intelligence lamp controller not necessarily is installed on the wall with the mains switch of light fixture, do not take the metope space, volume is less, and installation is placed very convenient; 3) by the fast quick-break of the mains switch of pushing light fixture/logical operation, realize the light modulation gear shift, simple to operate easily, need not direct control intelligence lamp controller; 4) when the mains switch of light fixture was opened, light fixture was in by secretly slowly rising to certain brightness, even the people opens light fixture under the environment of dark, because light is more weak and soft, human eye was had no adverse reaction, and effectively protected people's eyes; 5) for installing but there is not the light fixture of dimmer to rethink the installation light modulating device, need not rewiring and light modulating device is installed on the wall, install and place very conveniently, do not influence the decorative effect of the mains switch of original light fixture.
