The passive compatible light adjusting circuit in source.
Background technology
LED is the development direction of new century lighting engineering, compared to traditional electric filament lamp, fluorescent lamp etc.,
LED has that volume is little, life-span length, the advantage such as low in energy consumption, pollution-free, lucuriant in design.LED is as one
It is critically important for planting dimming light source.It is possible not only to obtain a environment the most comfortable, nowadays, reduces
Unnecessary non-light, realizes energy-saving and emission-reduction further and has become as a more importantly thing.For LED
For, it is achieved its light modulation is easier to realize for comparing other fluorescent lamp, electricity-saving lamp, high-pressure mercury lamp, institute
So that dimming function more should be added in all kinds of LED lamp.
The brightness of LED to be changed, is easily achieved.First it is envisioned that change its driving electric current,
Because the brightness of LED is almost the most proportional with its driving electric current.But the electric current of regulation LED
Simplest method is exactly to change and the current sense resistor of LED load series connection, nearly all DC-DC constant current
Chip has the interface of a detection electric current, is that the reference voltage of voltage and the chip internal detected compares,
Control the constant of electric current.But the value of this detection resistance is the least, only a little Europe of zero point, if wanted
The potentiometer filling an a little Europe of zero point on the wall is unlikely to regulate electric current, because lead resistance also can
There is several ohm of zero point.So some chip provides one to control voltage interface, just change the control voltage of input
Its output current value can be changed.
At present, LED meets 1-10V requirement of light regulation and also can accomplish, probably has a following several ways:
One, active dimmer adds modular converter scheme；Two, passive dimmer adds power supply module and adds modular converter
Scheme；Three, active or passive dimmer adds supply module plus modular converter scheme.
For scheme one (as shown in Figure 1), this scheme can use theoretically and just add a modular converter
Discernible 1-10V dimmer voltage signal can be exported, but owing to this scheme is defeated for different dimmers

Power supply cost, and it is only applicable to passive dimmer.
For scheme three (as shown in Figure 3), active or passive dimmer adds supply module plus modular converter
Scheme is similar to scheme two can realize compatible active passive 1-10V device light modulation, but due to the reason of power supply
With the reason of conversion, the volume of power supply and cost and processing technology both increase difficulty.
Understand based on above-mentioned analysis, a kind of small size of design, low cost, compatible LED1-10V good, high performance
Active passive compatibility light adjusting circuit is necessary.
