Advantages Of LED Displays

  1. Energy-efficient - LED’s are actually capable of outputting 135 lumens/watt
  2. Extende lifetime - 50, 000 hours or higher if properly designed
  3. Rugged - LED’s may known as “Solid State Lighting (SSL) as they are manufactured from solid material without any filament or tube or bulb to-break
  4. No warm-up duration - LED’s light instantly – in nanoseconds
  5. Not suffering from cold weather - LED’s “like” low temperatures and certainly will startup even in subzero weather condition
  6. Directional - With LED’s you can easily direct the light where you are interested, hence no light is wasted
  7. Exceptional Color Rendering - LED’s never wash-out colors like other light sources including fluorescents, making them perfect for shows and retail applications
  8. Environmentally friendly - LED’s contain no mercury or any other dangerous substances
  9. Controllable - LED’s can be managed for brightness and color

The reason why LED's tend to be selected for most programs

  • LEDs tend to be ideal for used in applications being at the mercy of regular on-off cycling, unlike fluorescent lamps that burn up faster when cycled usually, or HID lights that require a long time before restarting.
  • LEDs can effortlessly be dimmed or strobed
  • LEDs light rapidly. A normal purple indicator LED will attain full brightness in microseconds.
  • LEDs mainly fail by dimming as time passes, rather than the abrupt burn-out of incandescent bulbs
  • LEDs, being solid-state components, tend to be hard to damage with additional surprise, unlike fluorescent and incandescent bulbs which are delicate.
  • LEDs can be quite tiny and are usually easily populated onto imprinted circuit panels.
  • LEDs try not to contain mercury, unlike lightweight fluorescent lamps

Disadvantages and challenges in making use of LEDs

  • LEDs are currently higher priced, price per lumen, on a preliminary money price basis, than even more traditional lighting effects technologies. However, when contemplating the total price of ownership (including energy and upkeep expenses), LEDs far exceed incandescent or halogen resources and commence to threaten compact fluorescent lamps.
  • The Chart Below compares different light sources based upon living regarding the light bulb and the electric expense at 10 cents per kWh (kilowatt hour). Note: installation expenses and installation prices are perhaps not included.
  • LED performance largely varies according to precisely engineering the installation to handle heat produced by the LED, which causes deterioration associated with the Light-emitting Diode chip itself. Over-driving the LED or otherwise not engineering the product to manage heat in high background temperatures may end up in overheating associated with LED bundle, in the course of time resulting in unit failure. Adequate heat-sinking is required to preserve endurance. The most typical design of a heat sink is a metal device with several fins, which conducts heat away from the Light-emitting Diode. To learn more about this, reference the Thermal control loss.
  • LEDs should be provided with the most suitable voltage and present at a consistent flow. This requires some electronics expertise to create the digital drivers.
