Do You Know LED Downlight Dimming Applications From:http://www.lgiled.com   Reporter:   Date:2013/6/12 13:17:00   Tags:led-downlight-prices led-strip-lights-china cheap-led-strip-lights

The led downlight can emit wide beam and white light for us. It is more suitable for the large rooms. With the development of the technology,the lights are already updated to suit more demand and applications. The fixture of it can be powerful as well to provide more functions.

In the common sense,the leds are more welcomed by consumers,as they are energy saving and suitable features. For the certain need,the lights can be adjusted on the angle and lighting level. The ways of dimming applications show in several aspects. The ways are pulse width modulation and the frequency modulation and bit angle modulation scheme as well.

When it is in the first condition,the led brightness can be adjustable. The working theory is changing the width of the rectangular pulse current applied to the led on that the average current on it can be changed. Therefore,there will be a a larger range of dimming effect.

When it comes to the frequency modulation,the ways to change the brightness is different. A rectangular pulse applied to the led by varying the unit time and how much the number of the current that the average current on the led in the larger range changes. It will result in a larger range of adjustment so that the led light fixtures are more brightness.

The last way is bit angle modulation scheme. Use bunch containing a binary sequence of pulses, and each of a width of the pulse sequences in accordance with the proportion of its bit value to stretch. By changing the unit time applied to the led on the rectangular pulse; occupy bit value of the current in extendible width, so that the average current on the led changes within a large range, in order to adjust the led brightness.

Not only the led downlight dimming applications,various ways to adjust the led brightness are provided to us as well. When you choose a light,you are told to select online. According to your demand,a certain type of leds are involved. Then you should have a further selection and choose the most suitable one at last.
