Advantage and disadvantage of LED

Nowadays, LED has attract more and more attention from all of the world, correspondingly, it arise some debates on it is good or not?As the saying goes "Every coin has two sides", everything has its advantage and disadvantage, LED is no exception.
LED's advantage: 1.Energy saving – LED is 10 to 50 times more energy efficient than incandescent light bulb and reduces operating costs up to 90%。 2.Long lifespan – While most incandescent light products are only rated up to 3,000 hours, LED luminaires are up to 100,000 hours, or more than 10 years of continuous use. 3.Safety – Low-voltage power consumption and low heat output enhance operational safety and make LED luminaire cool and safe to touch during use. 4.Durability – LED lumianires are more durable than conventional bulbs and more resistant to breakage, failure, vibration, shock and temperature extremes. 5.Small size – High intensity, low weight and small volume that make luminaire design more flexible. 6.Instant response – No flicker, just pure dramatic light. 7.Quality light output – Minimal ultraviolet or infrared radiation. 8.Flexible design – Compared to traditional lighting devices, the aesthetic design of LED luminaire are much more unlimited. 9.Modulization – Flexible in luminaire design. 10.Special application – Can be pulsed or flashed.
LED disadvantage:
1.LED is currently more expensive than conventional lighting technologies. This is partly due to the relatively low lumen output of LED. However, since LED technology keeps improving and the energy expense sharply increases, we can still save money by using LED luminaries in the long run. 2.Thermal dissipation is the most relevant to the lifespan of LED but few firms can deal with it. Conventionally, fin, fan or heat sink base are used to dissipate the heat but there are a lot of limits for high-power LED lighting applications. In order to solve this serious problem, ATD proposes an innovative thermal technology that is perfect to LED lighting. According to the 3 years field test data, LHP has been proved to be the best heat dissipation technology which keeps the junction temperature lower than 65℃.
