Where can be application for LED in lighting field?
Grow lights composed of LEDs are more efficient, both because LEDs produce more lumens per watt than other alternatives, and also because they can be tuned to the specific wavelengths plants can make the most use of.
Light bulbs
Lanterns
Streetlights
Large scale video displays
Architectural lighting like led wall washer, led rope light, led tube light, led panel light and so on…
Light source for machine vision systems, requiring bright, focused, homogeneous and possibly strobed illumination.
Motorcycle and Bicycle lights
Flashlights, including some mechanically powered models.
Emergency vehicle lighting
Backlighting for LCD televisions and displays. The availability of LEDs in specific colors (RGB) enables a full-spectrum light source which expands the color gamut by as much as 45%.
Stage lights using banks of LED’s as replacement for incandescent bulbs. LED’s produce less heat so LED stage lighting is cheaper to operate and reduces the risk of fire considerably.
LED-based Christmas lights have been available since 2002, but are only now beginning to gain in popularity and acceptance due to their higher initial purchase cost when compared to similar incandescent-based Christmas lights. For example, as of 2006, a set of 50 incandescent lights might cost US$2, while a similar set of 50 LED lights might cost US$10. The purchase cost can be even higher for single-color sets of LED lights with rare or recently-introduced colors, such as purple, pink or white. Regardless of the higher initial purchase price, the total cost of ownership for LED Christmas lights would eventually be lower than the TCO for similar incandescent Christmas lights since the LED requires much less power to output the same amount of light as a similar incandescent bulb. More to the point, LEDs have practically unlimited life and are hard-wired rather than using unreliable sockets as do replaceable bulbs. So a set of LED lights can be expected to outlive many incandescent sets, and without any maintenance.
