LED lights are extremely small, point -shaped light sources, which often require optical lenses to spread the light forward in a useful way. LED technology and light yield has developed very rapidly , but is still not mature enough to be used in replacement to the stronger light bulbs at a reasonable price . There are many advantages of LEDs:
The lights are much more energy efficient than incandescent bulbs.
A life of up to 25 000 hours reduces maintenance costs and fewer lamps must be recycled .
LEDs can be manufactured so that they neither emit UV or IR radiation and therefore can be used to shed light on light-sensitive objects.
Luminaires with integratedgu10 led dimmable makes it possible to change color temperature as needed.
A disadvantage is that LED lighting with good color rendering and good color temperature so far is expensive.
LEDs have long been used as indicator lights on electronic equipment. In recent years, LED also begun to be used as accent lighting and floodlighting . They are also available as replacement for reflector lamps .
The trend is towards the use of LEDs in general lighting , mainly in offices and public places. LED is very interesting for street lighting because they can drastically lower the cost of relamping . The price of the purchase is still a limitation.
Common applications for LED lights are advanced optical communication equipment , electronics and appliances. Other applications are :
Thin , lightweight message boards ( information signs )
Fairy lights (like Christmas lights )
Status indicators (lights indicating on or off)
Bike lights , headlamps
Signal and emergency lighting
Replacement for reflector lamps
Small candle , for example, sconces and chandeliers
LED Christmas lights in
Energy Agency has tested Advent stars , fairy lights and Christmas tree lighting. The test showed that about one million households each have a window star, light strand and christmas ornaments , they can together save about 41 million kWh in choosing lighting with light emitting diodes, instead of incandescent bulbs. This corresponds to the defroster of 2700 homes for an entire year.
