Uses of LED

The main use of LED (Light Emitting Diodes) is to illuminate objects and spaces as well. Its application is ubiquitous due to its small size, low energy consumption, long life cycle and flexibility for applications in various applications.

Uses of LED

  • TV Backlighting
  • Smartphone Backlighting
  • LED displays
  • Automotive Lighting
  • Dimming of lights

The backlight of the TV is the most energy efficient. LEDs can be used to reduce energy effectively. Using LEDs on the edges of TVs will be cost effective. Using LEDs directly behind the screen provides excellent contrast. When it comes to TV backlighting, CFLs and LCDs have been replaced by LEDs.

The design of backlights in smartphones can be compact and cost-effective thanks to the use of LEDs. The number of LEDs may vary depending on the size of the smartphone. They provide longer battery life due to lower discharge rates.

Nowadays, LED display panels are common and used outdoors as storage panels, billboards, road signs, etc. In signs that have multiple signal transmission languages, the use of multiple LEDs will be advantageous in terms of energy efficiency.

The use of LEDs in the automotive industry is growing. LEDs are energy efficient and improve visibility. These are typically used at the back and rear of the vehicle for a better fit. LED lights can improve both pedestrian and driver safety because they increase visibility when turned on, off, and slowing down during travel.

  • Some LED solutions involve dimming the lights to help reduce energy consumption.
  • This dimming function is also used for Devices with dual functions.
  • Global Dimming Where all LEDs dim together.
  • Local dimming with LEDs independently.
  • These were some of the functions of LEDs. For more information, download THE BYJU Learning App.
