advantage:

1. Small size. The LED is basically a small chip that is encapsulated in epoxy, so it is very small and very light.
2. Low power consumption. LED power consumption is very low, generally the operating voltage of the LED is 2-3.6V. The operating current is 0.02-0.03A. This means that it consumes no more than 0.1W.
3. Long service life. LEDs have a service life of up to 100,000 hours at the right current and voltage
4. High brightness and low heat. LED technology is advancing with each passing day, its luminous efficiency is making amazing breakthroughs, and prices are constantly decreasing.
5. Environmental protection. LEDs are made of non-toxic materials, unlike mercury-containing fluorescent lamps that can cause contamination, and LEDs can be recycled.
6. Sturdy and durable. The LED is completely encapsulated in epoxy, which is stronger than both the bulb and the fluorescent tube. There are no loose parts in the lamp body. These features make the LEDs hard to damage.

Disadvantages:

1, the price is expensive, need constant current drive, heat dissipation is not easy to light decay.
2, the lighting brightness is small, not suitable for large-area lighting.
3, led lights will also be hot, need heat.
4, in the initial stage, LED lighting is mainly used in large-scale landscape lighting, not suitable for high-use eye environment, currently based on experiments.
5, LED can not be used as a simple light source; its use to drive power, optical and thermal conduction.
6, LED small lamp beads, after a few years of use will slowly wear out and can not be replaced, it is easy to cause the entire table lamp to be scrapped.
LED is the abbreviation of English light emitting diode. Its basic structure is an electroluminescent semiconductor material chip. It is cured with silver or white glue to the bracket, and then connected to the chip and circuit board with silver wire or gold wire. Then, it is sealed with epoxy resin to protect the inner core wire. Finally, the outer casing is installed, so the seismic performance of the LED lamp is good.
