Three kind LED dimmer analysis

More information from www.euchipsonline.com

    Nowadays the common use LED dimmer : Triac/ELV dimmer,Led 0/1-10v dimmer,PWM 

dimmer,The working principle of other dimmer is to achieve LED dimming function through 

control of the output current and voltage,frequency size. 

  Pls see the detailed principle under various dimming mode

1 LED triac dimming  is used in incandescent lamp and energy saving lamp,is one of the most 

widely used  dimming modes in Led dimming.

Its working principle is that the input voltage waveform generates a tangential

output voltage waveform  by conducting angle shear wave,The application of the principle of 

tangential, can reduce the effective value of the output voltage.so as to reduce the common 

load  (resistive load) power.The advantages of triac dimmer is high efficiency, stable 

performance.

2 LED 0/1-10V dimmer ,the power supply design with control chip.0-10V dimmer,

 through the 0-10V voltage change, change the output current of the power source

when 0-10V dimmer modulate to 0V, down to current 0,the brightness of the light is

closed ( a switch role),when the 0-10V dimmer tune the maximum 10V, the output current will 

reach 100% power output, the brightness will also 100%.output voltage is constant

 1-10V dimming principle: as noted that, just a dimmer is 1-10V: when the resistance dimmer to 

minimum 1V,change the output current is 10%,as to 10V (at maximum), the output current will 

reach 100%power output, the brightness will also 100%. (output voltageis constant)

   Note: 1-10V has no a switching function.

3 PWM dimming power  digital dimming is also called PWM dimming, through the PWM wave to open 

and close the LED forward current to change the conduction time, in order to achieve the effect 

of brightness adjustment.The method is based on properties that  human eye is not sensitive to 

brightness scintillation. If the bright and dark  frequency exceeds 100Hz,the average brightness

 is seen by the human eye, instead of LED in the blink. PWM can adjust brightness by adjusting 

the proportion of time of dark and light,because the human eye to  more than 100Hz in the flicker 

of light, the perception of brightness is a cumulative process.

  

Led fluorescent lamp power supply mode

    Led fluorescent lamp power supply generally divided into two kinds:built-in

and external.

    The built-in type refers to the power supply can be placed inside the tubes.

  The biggest advantage of this built-in is can be made directly replace the

exsisting fluorescent lamp tube,without the need for any change.

    So the shape of build in is made into strip to be filled into

semicircular tube.

    Analysis of non isolated and isolated .

    Non isolated constant current power supply, non isolation refers to the 

load end and the input end is connected directly,so the risk of electric shock

load is touch.At present, the most used is non isolated buck type power supply.

       

      Alternating current rectification after DC high voltage

then the direct use of buck circuit for Buck and constant current control.Advantages of non isolated

constant current source is simple, index is high, its output current can be a number according to LED 

series parallel decision. But in most cases, the output current for it cannot be too large, the output 

voltage can not be too high.The advantage of  built-in power is the ability to directly  replace the 

existing fluorescent lamp using the inductance ballast, without the need to remove anything.

     Centralized external power  in order to get the maximum performance .It's best to

use centralized external power supply. The promotion of LED fluorescent lamp power 

supply places are government agencies, offices, shopping malls, schools, underground 

parking, subway and other places.

   Centralized refers to the AC/DC switching powersupply,,the use of a large power unified power 

supply, and eachfluorescent lamp using the constant current moduleseparate DC/DC. 

You can get the bet efficiency.

The choice element of LED power

  Led is a kind of environmental friendly power.It is believed that every one

is

familiar with it.So,Do you know what is the choice factors? Let's look into the

Euchips LED dimming power .The following are the details

    Led is a kind of environmental friendly power.It is believed that every one

is

familiar with it.So,Do you know what is the choice factors? Let's look into the

Euchips LED dimming power .The following are the details.

  Leakage power -- LED is a one-way conductive light- emitting body.If there is

reverse current.It is called leakage.The leakage current of LED ,short 

service,Low price.

       Light angle--the light emitting angle is not the same according to various uses of Led power

Light emitting angle is special, the price is higher

The service life - different quality is the key of life.Life is decided by the

light fades.

      Chip: Chip is illuminant of LED , the price varies great according to different chip.

The length of chip indicate the size of the chip.  the quality of bigger LED chips is better than small. 

The price of the  chip size is proportional to it's size.

     
      Colloid: General epoxy resin,LED is more expensive with UV and fire retardant

, high-quality outdoor LED lighting should be UV and fire resistant.

Brightness - The price is different with different Led brightness. For the LED lamp LED should 

meet grade I standard laser.

Anti static ability : the stronger anti static ability of the LED, the longer service life of LED ,and higher 

prices.

The Endless Possibilities Of DMX Lighting Control Software

The DMX lighting control software  control a lighting atmosphere intelligently  that has several lighting gadgets. These gadgets are digitally controlled through a controller. The lighting gadgets applied in top notch stage performances, shows, openings of events etc, are controlled by the DMX lighting controller now. What does this precisely mean? To fully grasp this let us get much more familiar with what DMX means. DMX is an acronym used for a Digital Multiplex. What does this precisely do and how is it linked to the a number of lighting elements in a disco?
The DMX lighting controller powered system has the following components that are 1) a DMX lighting control software controller, 2) a DMX cable, 3) a DMX decoder and 4) a lighting product. The DMX lighting control software transmits signals to the lighting elements linked to it through 512 channels. The lighting element acts based on the instruction from the decoder that is in turn connected to the DMX lighting controller panel through the DMX cable. The lighting components, these days are capable of taking, simultaneously commands from five different channels. Let us consider an example of a lighting device and fully grasp this set up.

The DMX lighting control software that connects a moving electric light in a discotheque might have several features like movement, lights, colors and intensity of light etc., the DMX lighting control| software transmits 512 different signals at a time. However, say the moving light is set to accept the signal from channels seventeen, 18, nineteen, 20 wherein each number corresponds to the components like movement, number of lights to be switched on or off, coloration, intensity respectively and afterwards the corresponding numbers could only be interpreted by the DMX lighting control software decoder. All the rest of the channels transmitted through the DMX lighting control software controller, are disregarded by the decoder installation in the moving light.

The DMX lighting control software transmits electronic signals 44 times in every second through all its 512 channels. Incredible isn't it? Well, that is the sophistication of this software. Lighting carried out by this method offers great effects and the visible glory is absolutely indefinable. The signal transmitted through 512 channels through DMX lighting wires is called a DMX lighting control software universe. When there is a need of more than 512 channels for operating a particular lighting device or a group of gadgets, one may go for several DMX control software universes.
