Voltage: LED using low-voltage power supply, supply voltage between 6-24V, depending on the product varies, so it is a more secure power supply than the use of high-voltage power supply, especially suitable for public places.
Efficiency: 80% reduction in energy consumption compared to incandescent lamps with light efficiency
Applicability: Very small, each unit LED small piece is 3-5mm square, so can be prepared into a variety of shapes of devices, and suitable for the variable environment
Stability: 100,000 hours, light decay for the initial 50%
Response Time: The response time of its incandescent lamp is millisecond, and the response time of the LED lamp is nanosecond level
Environmental pollution: No harmful metallic mercury
Color: Light emitting diode easily through the chemical modification method, adjust the material's energy band structure and band gap, to achieve red and yellow green basket orange multi-color luminescence.
Price: LED Price is more expensive, compared to incandescent lamps, the price of an LED can be comparable to the price of a few incandescent lamps, and usually each set of signal lights need to be made up of 300~500 diode.
