LED Driver
A light-emitting diode driver, or LED driver, is an electronic component that controls the power to a single LED component or a series of LED bulbs or devices. These drivers are particularly useful in applications where the power needs of the LED components vary. They are also a good solution to keep the LED components' power levels consistent when the needs vary due to temperature variances that are commonly associated with LED components.
Importance of a Quality LED Driver in Your Electronic Product
Without a quality LED driver in your electronic product, you risk the product burning out prematurely. Not only is this bad for business since no one wants to spend their hard-earned money on a product that won't last long, but it is also a safety hazard because of the risk of the component catching fire when it gets overheated.
A quality LED driver can also help to prevent the electronic device from consuming an unusually large amount of energy because of unregulated power consumption by the LED. The reason why these drivers can help to conserve electricity is because an LED is a power-driven component in which the brightness of the LED is directly controlled by the amount of power supplied to the LED. Without regulation, the LED becomes something akin to a power-sucking vacuum that will pull power without limit.
Overall, you have to choose an LED driver that offers the functionality you need for your electronic devices without having to spend too much on the drivers. Consumers want the most bang for their buck, so you have to come to a suitable compromise between cost and quality according to the needs of your customer base and the desire you have regarding the longevity of use for the products.
Types of LED Drivers for Your Electronic Components
The exact type of LED driver you need depends on the specifications of your electronic components. Larger drivers are suitable for applications such as televisions, while smaller drivers are suitable for applications like smart phones. You also have to consider the weight of the driver. You don't want a heavy driver for an electronic application that is handheld, such as a handheld video game.
You have to determine the type of current you need. LED drivers are available in AC/DC models or DC/DC models. An AC/DC LED driver is the more efficient of the two. It is suitable for applications where dimming of the light is desirable. A DC/DC LED driver is best used for wide-input and output ranges in a variety of applications.
Another consideration you must think about is the control module for the LED driver. You can opt to use a microprocessor or a one-wire control, depending on your application. The microprocessor option gives you a little more control over the function of the driver, but the one-wire control offers a compact solution for micro-applications.
