What’s the LED Dimming Accomplished and How It's Work?

Image
The light output of LEDs can be controlled by varying the amount of current flowing through the LED( within defined limits) or by turning the LED on and off via pulse width modulation( PWM). LED drivers like the ALD6 series can provide “ dimming ” by both of these popular methods. The drawing above shows the two light-dimming styles included in the ALD6 LED driver. It's permitted to use a combination of both of these methods simultaneously in  Opto Electronics . The “ Rbr ” is an external variable 10kohm resistor input. By varying this potentiometer from 1k to 10k ohms, analog dimming control is achieved. In this case, the maximum LED brightness occurs when the pot is set to 10k ohms. This same input can operate with variable analog voltage ranging from1.6 to3.8- volts. In some applications this input can be connected to a temperature sensing device which could reduce the current inflow through the LEDs as the temperature rises, providing a means for temperature compensation. The ...

What Is a Microcontroller?

Image
A microcontroller is an integrated circuit( IC) device used for controlling other portions of an electronic system, generally via a microprocessor unit( MPU), memory, and some peripherals. These devices are optimized for embedded operations that require both processing functionality and agile, responsive interaction with digital, analog, or electromechanical components. The most common way to refer to this order of integrated circuits is “ microcontroller" but the abbreviation “ MCU ” is used interchangeably as it stands for “ microcontroller unit ”. You may also occasionally see “ µC ”( where the Greek letter mu replaces “ micro ”). “ Microcontroller ” is a well-chosen name because it emphasizes defining characteristics of this product category. The prefix “ micro ” implies smallness and the term" regulator" then implies an enhanced ability to perform control functions. As stated over, this functionality is the result of combining a digital processor and digital memory ...

What’s the Difference Between Passive and Active Components?

Image
Do you know what passive devices are? While engineers and designers within your association know, procurement personnel may not be up to speed with passive devices. However, you’ve come to the right place! If you’ve been involved with-procurement or supply chain processes and your curiosity about passive electronic components is anything but passive. At Rabyte, we empower purchasing departments and procurement specialists every day. And a little extra knowledge about those items on a Bill of Material( BOM) or invoice benefits everyone. Passive vs. Active Understanding Electronic element Functionality Most electronic devices and parts are distinguished by how they interact with electricity. In this regard, there are two main types Active components- Active electronic devices are suitable to manipulate electricity, plain and simple. suppose of diodes( basically, one-way electricity conduits) and LEDs as active electronic components. Transistors are another great example of an active de...
