LED light features
1. LED characteristics
The inherent characteristics of LED determine that it is the most ideal light source to replace the traditional light source, and it has a wide range of uses.
1. Small size
The LED is basically a small chip encapsulated in epoxy, so it is very small and very light
2. Low power consumption
The power consumption of LED is not low, generally speaking, the working voltage of low-power LED is 2-3. 6y. The working current is 0 02-0.03Aen
That is to say: it consumes no more than 0.1W of electricity. The working voltage of high-power LED is 3-3. 5V, the working current is 300- 360mA,
The power is about 1 watt.
3. Long service life
Under the proper current and voltage, with good heat dissipation, the life of the LED can reach 100,000 hours.
4, high brightness, low heat
The same lighting effect saves more than 80% energy than traditional light sources, and has less heat radiation than HID or incandescent lamps.
5. Environmental protection
LEDs are made of non-toxic materials, unlike fluorescent lamps that contain mercury, which can cause pollution, and LEDs can also be recycled and reused.
Red LEDs contain a large amount of As (arsenic), which is highly toxic
6. Sturdy and durable
LEDs are completely encapsulated in epoxy resin, which is stronger than light bulbs and fluorescent tubes. The lamp body is not loose
part, these characteristics make the LED can be said to be not easy to damage.
7. Strong controllability
Various color changes can be achieved. Changing the current can change color, light-emitting diodes are easily modified by chemical methods,
Adjust the energy band structure and band gap of the material to achieve multi-color emission of red, yellow, green, blue and orange. Such as the red led when the current is small, with the current
The flow increases, which can turn orange, yellow, and finally green in sequence
