LEDs offer a huge variety of benefits but at the same time they cannot be viewed as the optimum solution for every lighting-related application. Here, in no particular order, we list some of the main advantages of LEDs, together with some of the challenges faced by these devices.
As solid-state light sources, LEDs have very long lifetimes and are generally very robust.
Various standards relating to LEDs exist in areas such as automotive lighting and traffic signals.
- Low maintenance
The long lifetime of LEDs reduces the need to replace failed lamps, and this can lead to significant savings, particularly in the cost of sending out maintenance crews.
White LEDs with efficacies of 25 lm/W and up are commercially available, exceeding the performance of incandescent and some fluorescent sources.
- Low power consumption
The low power consumption of LEDs leads to significant energy savings that can often drive the installation of LED-based systems.
Although LEDs have high efficiency and consume a small amount of power, the devices produce a small total number of lumens.
LEDs don't produce heat in the form of infrared radiation, which makes incandescent bulbs hot to the touch.
LED manufacturers continue to work towards reducing their production costs while at the same time increasing the light output of their devices.
- Small form-factors
LEDs are very small - typical high-brightness LED chips measure 0.3 mm by 0.3 mm, while high-power devices can be 1 mm x 1 mm or larger.
- Instantaneous switch-on
LEDs switch on rapidly, even when cold, and this is a particular advantage for certain applications such as vehicle brake lights.
